AI Tools for VB.NET – Dr. Trippers Stuff

Visual Basic.net is there an AI that I can access specifically for programming?
I am building a very simple video viewer using VB.Net and VS Community 2022. I will be using webview2. I have a form with webview2 control already. I need the control to be droppable so I can drag link from a browser and drop it on the control, it should load but not play until commanded. I want a tabbed control so that I can drop several links onto the form with each link adding a new tab. Each should have separate volume controls and play independently of each other. List the step by step instructions and then code for each step

Sure, here are the step-by-step instructions for achieving your goal:

Step 1: Create a new project in Visual Studio Community 2022 and add a form to it.

Step 2: Add a WebView2 control to the form. You can do this by dragging and dropping it from the toolbox onto the form.

Step 3: Set the AllowDrop property of the WebView2 control to True to enable dropping of links onto it.

Step 4: Create a new tabbed control. You can use the TabControl control provided by Visual Studio for this purpose.

Step 5: Add a new tab to the tabbed control whenever a link is dropped onto the WebView2 control. You can do this by handling the DragDrop event of the WebView2 control.

Step 6: When a link is dropped onto the WebView2 control, load the link into a new instance of the WebView2 control and add it to the newly created tab. You can use the Navigate method of the WebView2 control to load the link.

Step 7: Add a volume control to each tab. You can use the TrackBar control provided by Visual Studio for this purpose.

Step 8: Add a play/pause button to each tab. You can use the Button control provided by Visual Studio for this purpose.

Step 9: When the play/pause button is clicked, play or pause the video in the corresponding WebView2 control. You can use the Play or Pause method of the WebView2 control for this purpose.

Here is the sample code for achieving this functionality:

“`
‘ Step 3
webView2.AllowDrop = True

‘ Step 5
Private Sub WebView2_DragDrop(sender As Object, e As DragEventArgs) Handles WebView2.DragDrop
Dim link As String = e.Data.GetData(DataFormats.Text)
Dim newTab As New TabPage(link)
Dim newWebView2 As New WebView2()
newWebView2.Dock = DockStyle.Fill
newWebView2.Tag = link
newWebView2.Source = New Uri(link)
newTab.Controls.Add(newWebView2)
TabControl1.TabPages.Add(newTab)
End Sub

‘ Step 7
Private Sub TabControl1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles TabControl1.SelectedIndexChanged
Dim selectedTab As TabPage = TabControl1.SelectedTab
Dim webView2 As WebView2 = selectedTab.Controls.OfType(Of WebView2)().FirstOrDefault()
Dim volumeControl As New TrackBar()
volumeControl.Minimum = 0
volumeControl.Maximum = 100
volumeControl.Value = webView2.Volume * 100
volumeControl.Dock = DockStyle.Bottom
AddHandler volumeControl.Scroll, AddressOf VolumeControl_Scroll
selectedTab.Controls.Add(volumeControl)
End Sub

‘ Step 8
Private Sub TabControl1_Selected(sender As Object, e As TabControlEventArgs) Handles TabControl1.Selected
Dim selectedTab As TabPage = e.TabPage
Dim webView2 As WebView2 = selectedTab.Controls.OfType(Of WebView2)().FirstOrDefault()
Dim playButton As New Button()
playButton.Text = “Play”
playButton.Dock = DockStyle.Top
AddHandler playButton.Click, Sub()
If webView2.IsPlaying Then
webView2.Pause()
playButton.Text = “Play”
Else
webView2.Play()
playButton.Text = “Pause”
End If
End Sub
selectedTab.Controls.Add(playButton)
End Sub

‘ Step 9
Private Sub VolumeControl_Scroll(sender As Object, e As EventArgs)
Dim selectedTab As TabPage = TabControl1.SelectedTab
Dim webView2 As WebView2 = selectedTab.Controls.OfType(Of WebView2
How do I make webview2 droppable so I can drag link and drop them on the control and have it navigate to that link?
please continue with step 9
To make the WebView2 control droppable, you can handle the DragOver and DragDrop events of the control. Here’s an example code snippet that demonstrates how you can achieve this:

“`vb.net
Private Sub WebView2_DragOver(sender As Object, e As DragEventArgs) Handles WebView2.DragOver
If e.Data.GetDataPresent(DataFormats.Text) Then
e.Effect = DragDropEffects.Link
End If
End Sub

Private Sub WebView2_DragDrop(sender As Object, e As DragEventArgs) Handles WebView2.DragDrop
Dim url As String = e.Data.GetData(DataFormats.Text).ToString()
WebView2.CoreWebView2.Navigate(url)
End Sub
“`

In this code, the `DragOver` event handler checks if the dragged data is in the form of text, and if so, sets the `Effect` property of the `DragEventArgs` to `DragDropEffects.Link` to indicate that a drop operation is allowed. In the `DragDrop` event handler, we retrieve the URL from the dragged data and navigate the WebView2 control to that URL using the `Navigate` method of the `CoreWebView2` object.

With this code in place, you should be able to drag and drop links onto the WebView2 control to navigate to them.
)().FirstOrDefault()
Dim volumeControl As TrackBar = TryCast(sender, TrackBar)
If webView2 IsNot Nothing AndAlso volumeControl IsNot Nothing Then
webView2.Volume = volumeControl.Value / 100.0F
End If
End Sub
“`

This code sets up the necessary functionality for your video viewer application. You can customize the code further to suit your specific requirements.
error saying webview2 is not declared? Public Class Form1
Public Property AllowExternalDrop As Boolean
Private Sub WebView21_Click(sender As Object, e As EventArgs)

End Sub
Private Sub WebView2_DragOver(sender As Object, e As DragEventArgs) Handles WebView2.DragOver
If e.Data.GetDataPresent(DataFormats.Text) Then
e.Effect = DragDropEffects.Link
End If
End Sub

Private Sub WebView21_Click_1(sender As Object, e As EventArgs) Handles WebView21.Click

End Sub
End Class

Should this code go in form load?
It looks like you may not have added the `WebView2` control to your form, or you may not have imported the necessary namespaces.

To add the `WebView2` control to your form, you can follow these steps:

1. Open the Toolbox window in Visual Studio by selecting “View > Toolbox” from the menu.
2. Right-click in the Toolbox and select “Choose Items”.
3. In the “Choose Toolbox Items” window, select the “.NET Framework Components” tab.
4. Scroll down and select the “Microsoft.Web.WebView2.WinForms” component, then click OK.
5. The `WebView2` control should now be added to the Toolbox. You can drag it onto your form to add it to your user interface.

In addition, you need to import the following namespaces at the top of your code file:

“`vb.net
Imports Microsoft.Web.WebView2.Core
Imports System.Windows.Forms
“`

With these changes, the error saying `WebView2 is not declared` should be resolved.
The code for setting the `AllowDrop` property of the `WebView2` control to `True` should be added in the `Form_Load` event. You can add the rest of the code to their respective event handlers.

So, the code for Step 3 should be added to the `Form_Load` event handler, like this:

“`
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
webView2.AllowDrop = True
End Sub
“`

The code for Steps 5, 7, 8, and 9 should be added to their respective event handlers, like `WebView2_DragDrop`, `TabControl1_SelectedIndexChanged`, `TabControl1_Selected`, and `VolumeControl_Scroll`.
The code works but when I drop a link on it this happen A new window open up.
I don’t see the webview2 control on the toolbox and no option to install it
If a new window is opening up when you drop a link onto the WebView2 control, it’s likely because the default behavior of the control is to open links in a new window. To change this behavior and have links open in the same WebView2 control, you can handle the `NewWindowRequested` event and navigate to the requested URL in the current control.

Here’s an updated code snippet that handles the `NewWindowRequested` event to prevent new windows from opening:

“`vb.net
Private Sub WebView2_DragOver(sender As Object, e As DragEventArgs) Handles WebView2.DragOver
If e.Data.GetDataPresent(DataFormats.Text) Then
e.Effect = DragDropEffects.Link
End If
End Sub

Private Sub WebView2_NewWindowRequested(sender As Object, e As CoreWebView2NewWindowRequestedEventArgs) Handles WebView2.NewWindowRequested
e.Handled = True
WebView2.CoreWebView2.Navigate(e.Uri)
End Sub
“`

In this code, the `NewWindowRequested` event handler sets the `Handled` property of the `CoreWebView2NewWindowRequestedEventArgs` parameter to `True` to prevent the default behavior of opening a new window, and then navigates to the requested URL in the current control using the `Navigate` method of the `CoreWebView2` object.

With these changes, dropping a link onto the WebView2 control should now navigate to the link in the current control, without opening a new window.
It sounds like the `AllowWebBrowserDrop` property of the `WebView2` control may not be set to `True`. When this property is set to `False`, dropping a link on the control can cause a new browser window to open instead of navigating to the dropped URL.

To fix this issue, you can set the `AllowWebBrowserDrop` property of the `WebView2` control to `True`. Here’s an updated example code snippet:

“`vb.net
Private Sub WebView2_DragOver(sender As Object, e As DragEventArgs) Handles WebView2.DragOver
If e.Data.GetDataPresent(DataFormats.Text) Then
e.Effect = DragDropEffects.Link
End If
End Sub

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
WebView2.AllowWebBrowserDrop = True
End Sub
“`

In this code, we added a `Form1_Load` event handler that sets the `AllowWebBrowserDrop` property of the `WebView2` control to `True`. With this property set, dropping a link on the control should now navigate to the dropped URL without opening a new window.
If you can’t see the `WebView2` control in the Toolbox, you may need to install the WebView2 Runtime and SDK components from the Microsoft Edge Developer website.

Here are the steps to install the WebView2 components:

1. Go to the Microsoft Edge Developer website: https://developer.microsoft.com/en-us/microsoft-edge/webview2/
2. Click the “Get WebView2” button.
3. Scroll down to the “Stable channel” section and download the appropriate runtime installer for your system.
4. Install the WebView2 Runtime by running the installer you downloaded.
5. Scroll down to the “SDK” section and download the appropriate SDK installer for your system.
6. Install the WebView2 SDK by running the installer you downloaded.

After installing the WebView2 components, restart Visual Studio and open your project. You should now be able to see the `WebView2` control in the Toolbox.

If you still can’t see the `WebView2` control in the Toolbox, you can try adding it manually. To do this, right-click on the Toolbox and select “Choose Items…”. In the “Choose Toolbox Items” dialog, select the “.NET Framework Components” tab and click the “Browse…” button. Navigate to the “Microsoft.Web.WebView2.WinForms.dll” file in the “bin” folder of your project and click the “OK” button. The `WebView2` control should now be added to the Toolbox.
How do I set the control to automatically resize to fill the container
can I do this through nuget
To make the `WebView2` control automatically resize to fill its container, you can use the `Dock` property of the control.

Here’s how you can set it up:

1. Select the `WebView2` control on your form.
2. In the Properties window, locate the `Dock` property and set it to `Fill`.

Alternatively, you can set the `Dock` property programmatically in your code:

“`vb.net
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
WebView2.Dock = DockStyle.Fill
End Sub
“`

In this example code, we set the `Dock` property of the `WebView2` control to `DockStyle.Fill` in the `Form1_Load` event handler. This will cause the control to fill its container and automatically resize as the container is resized.
Yes, you can also install the WebView2 control using NuGet.

Here are the steps to install the WebView2 control using NuGet:

1. Right-click on your project in the Solution Explorer and select “Manage NuGet Packages…” from the context menu.
2. In the “NuGet Package Manager” dialog, select the “Browse” tab.
3. In the search bar, type “Microsoft.Web.WebView2” and press Enter.
4. Select the “Microsoft.Web.WebView2” package from the list of search results.
5. Click the “Install” button to install the package.
6. After the installation is complete, you should be able to see the `WebView2` control in the Toolbox.

Note that installing the WebView2 control using NuGet will also install the necessary runtime and SDK components.
Drop link still open a new window even with AllowExternalDrop = True?
webview2 uses microsoft technology. Is it based on edge or chromium?
If you have set the `AllowExternalDrop` property of the `WebView2` control to `True` and you are still experiencing issues where dropping a link on the control opens a new window, there may be a couple of other things you can try.

1. Set the `AllowNavigation` property of the `WebView2` control to `True`. This property allows the control to navigate to new pages.

“`vb.net
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
WebView2.AllowExternalDrop = True
WebView2.AllowNavigation = True
WebView2.Dock = DockStyle.Fill
End Sub
“`

2. Handle the `NewWindowRequested` event of the `CoreWebView2` object and set the `Handled` property of the event arguments to `True` to prevent the new window from opening.

“`vb.net
Private Sub WebView2_CoreWebView2_NewWindowRequested(sender As Object, e As CoreWebView2NewWindowRequestedEventArgs) Handles WebView2.CoreWebView2.NewWindowRequested
e.Handled = True
End Sub
“`

In this code, we added an event handler for the `NewWindowRequested` event of the `CoreWebView2` object. This event is raised when the web page requests to open a new window. By setting the `Handled` property of the event arguments to `True`, we prevent the new window from opening and force the link to be opened in the existing control.

Try adding these changes to your code and see if they resolve the issue.
WebView2 is a web control library developed by Microsoft that allows developers to embed web content in their applications. WebView2 is based on the Chromium engine, which is the same engine used by the Microsoft Edge browser.

Microsoft Edge switched to the Chromium engine in 2019, and WebView2 was introduced in 2020 as a replacement for the legacy WebView control. WebView2 allows developers to embed web content in their applications using the same engine that powers Microsoft Edge, which offers better compatibility with modern web standards and improved performance compared to the legacy WebView control.
getting error that AllowNavigation ios not a member of webview2
DO it come with built in security?
I apologize for the confusion. The `AllowNavigation` property does not exist in the `WebView2` control. Instead, you can set the `IsWebMessageEnabled` property to `True`. This property enables the `WebView2` control to navigate to new pages.

Here’s an updated example:

“`vb.net
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
WebView2.AllowExternalDrop = True
WebView2.IsWebMessageEnabled = True
WebView2.Dock = DockStyle.Fill
End Sub
“`

With this change, you should be able to drop links on the `WebView2` control and navigate to the dropped URLs without opening a new window.
Yes, WebView2 includes built-in security features that are designed to help protect your application and its users from various security threats.

Here are some of the security features provided by WebView2:

1. Sandboxing: WebView2 runs web content in a sandboxed environment, which helps prevent malicious code from affecting the rest of your application or the user’s system.

2. Isolation: WebView2 isolates web content from the rest of your application, which helps prevent cross-site scripting (XSS) and other types of attacks.

3. Same-origin policy: WebView2 enforces the same-origin policy, which prevents web content from accessing resources on a different domain.

4. Certificate validation: WebView2 validates the digital certificates presented by web servers to ensure that they are valid and issued by a trusted authority.

5. Content security policy (CSP): WebView2 supports the use of CSP headers, which allow web developers to specify which types of content can be loaded by their web pages.

6. Automatic updates: WebView2 is updated automatically along with the Microsoft Edge browser, which helps ensure that security vulnerabilities are patched quickly.

It’s important to note, however, that WebView2 is just one part of your application’s security posture. You should also take other steps to secure your application, such as validating user input, using secure communication protocols, and implementing strong authentication and authorization mechanisms.
Same error: IsWebMessageEnabled is not a member of webview2
Is this correct
I apologize for the confusion. The `IsWebMessageEnabled` property is only available in WebView2 version 1.0 or higher.

If you are using an older version of WebView2, you can try setting the `AreBrowserAcceleratorKeysEnabled` property to `False`. This property disables the default accelerator keys of the control, which can sometimes interfere with drag-and-drop operations.

Here’s an example:

“`vb.net
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
WebView2.AllowExternalDrop = True
WebView2.AreBrowserAcceleratorKeysEnabled = False
WebView2.Dock = DockStyle.Fill
End Sub
“`

With this change, you should be able to drop links on the `WebView2` control and navigate to the dropped URLs without opening a new window.
I’m sorry, I’m not sure what you’re referring to. Could you please provide more context or clarify your question?
BC31412 ‘Handles’ in classes must specify a ‘WithEvents’ variable, ‘MyBase’, ‘MyClass’ or ‘Me’ qualified with a single identifier.

Friend WithEvents TabControl1 As TabControl
Friend WithEvents TabPage1 As TabPage
Friend WithEvents TabPage2 As TabPage
Friend WithEvents WebView2 As Microsoft.Web.WebView2.WinForms.WebView2
The error message you received indicates that the `Handles` clause in your method signature is not correctly specifying the object that raises the event. To fix this error, you need to add the `WithEvents` keyword to your declaration of the `WebView2` control.

Here’s an updated example:

“`vb.net
Public Class Form1
Private WithEvents WebView2 As New WebView2

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
WebView2.AllowExternalDrop = True
WebView2.AreBrowserAcceleratorKeysEnabled = False
WebView2.Dock = DockStyle.Fill
Me.Controls.Add(WebView2)
End Sub

Private Sub WebView2_DragOver(sender As Object, e As DragEventArgs) Handles WebView2.DragOver
If e.Data.GetDataPresent(DataFormats.Text) Then
e.Effect = DragDropEffects.Link
End If
End Sub

Private Sub WebView2_NewWindowRequested(sender As Object, e As CoreWebView2NewWindowRequestedEventArgs) Handles WebView2.CoreWebView2.NewWindowRequested
e.Handled = True
End Sub
End Class
“`

In this code, we added the `WithEvents` keyword to the declaration of the `WebView2` control, which allows us to handle its events using the `Handles` clause in our method signatures. We also added an event handler for the `NewWindowRequested` event of the `CoreWebView2` object to prevent new windows from opening.

With these changes, you should be able to drag and drop links onto the `WebView2` control without opening new windows.
This code appears to be a declaration of the `TabControl` and `TabPage` controls, as well as the `WebView2` control, in a VB.NET form.

The `TabControl` control is used to create a tabbed interface, where each tab represents a different view or content. The `TabPage` control is used to define the content that appears in each tab.

The `WebView2` control is the Microsoft implementation of the Chromium-based WebView control, which allows you to embed web content in your application. The `Microsoft.Web.WebView2.WinForms.WebView2` namespace contains the `WebView2` control for use in Windows Forms applications.

By declaring these controls in the form’s code, you can use them to build the desired user interface and implement the necessary functionality.
error says this should be ‘with events’: Private Sub WebView2_CoreWebView2_NewWindowRequested(sender As Object, e As CoreWebView2NewWindowRequestedEventArgs) Handles WebView2.CoreWebView2.NewWindowRequested
e.Handled = True
End Sub
Error saying webview2 type not defined
The error message you received indicates that the `Handles` clause in your method signature is not correctly specifying the object that raises the `NewWindowRequested` event. To fix this error, you need to add the `WithEvents` keyword to your declaration of the `WebView2` control.

Here’s an updated example:

“`vb.net
Public Class Form1
Private WithEvents WebView2 As New WebView2

Private Sub WebView2_DragOver(sender As Object, e As DragEventArgs) Handles WebView2.DragOver
If e.Data.GetDataPresent(DataFormats.Text) Then
e.Effect = DragDropEffects.Link
End If
End Sub

Private Sub WebView2_CoreWebView2_NewWindowRequested(sender As Object, e As CoreWebView2NewWindowRequestedEventArgs) Handles WebView2.CoreWebView2.NewWindowRequested
e.Handled = True
End Sub
End Class
“`

In this code, we added the `WithEvents` keyword to the declaration of the `WebView2` control, which allows us to handle its events using the `Handles` clause in our method signatures. We also updated the method signature for the `NewWindowRequested` event handler to specify that the `WebView2` control is the object that raises the event.

With these changes, you should be able to drag and drop links onto the `WebView2` control without opening new windows.
This error typically occurs when the required `Microsoft.Web.WebView2` namespace is not properly referenced in your VB.NET project.

To resolve this error, you need to add a reference to the `Microsoft.Web.WebView2` assembly in your project. Here are the steps to do this:

1. Right-click on your project in the Solution Explorer and select “Add” > “Reference…” from the context menu.

2. In the “Reference Manager” dialog, select the “Browse” tab.

3. Navigate to the directory where WebView2 is installed (e.g., “C:Program Files (x86)Microsoft SDKsWebView2NuGetPackagesMicrosoft.Web.WebView2.0.9.579libnetstandard2.0”) and select the `Microsoft.Web.WebView2.WinForms.dll` file.

4. Click the “Add” button to add the reference to your project.

5. Save your changes and rebuild your project.

After adding the reference to the `Microsoft.Web.WebView2` assembly, you should be able to use the `WebView2` control in your VB.NET code without any errors.
I cannot find it in references, but it is in dependencies
If you cannot find the `Microsoft.Web.WebView2` reference under the “Assemblies” tab of the “Reference Manager” dialog in Visual Studio, but it appears in the “Dependencies” section of your project, it’s possible that your project is configured to use the WebView2 NuGet package instead of the assembly reference.

In this case, you can add the WebView2 NuGet package to your project by following these steps:

1. Right-click on your project in the Solution Explorer and select “Manage NuGet Packages” from the context menu.

2. In the “NuGet Package Manager” dialog, select the “Browse” tab.

3. Search for “Microsoft.Web.WebView2” in the search box.

4. Select the latest version of the package from the list of search results and click the “Install” button.

5. Accept the license agreement and wait for the package to be downloaded and installed.

After installing the WebView2 NuGet package, you should be able to use the `Microsoft.Web.WebView2` namespace in your code without any errors.
what does scope to this do?
“Scope to this” is an option that is available when you right-click on a file in the Solution Explorer in Visual Studio.

When you select “Scope to this” for a file, the Solution Explorer will only show the items related to that file, hiding everything else in the project. This can be helpful when working with large projects or when you want to focus on a specific area of code.

For example, if you select “Scope to this” for a code file in a project, the Solution Explorer will only show the related code files, namespaces, classes, and methods, hiding any other files or resources that are not directly related to that code. This can make it easier to navigate the project and find what you’re looking for.

It’s important to note that “Scope to this” does not actually change the structure of your project or modify any of the files. It simply changes the way that Visual Studio displays the project in the Solution Explorer to make it easier to work with.
In the project what should currently be inside the form1_load sub now?
Based on the code we have discussed so far, the `Form1_Load` sub should contain the following code:

“`vb.net
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
‘ Initialize the WebView2 control
WebView2.EnsureCoreWebView2Async(Nothing)

‘ Create a new tab and add it to the TabControl
Dim newTab As New TabPage()
TabControl1.TabPages.Add(newTab)

‘ Create a new WebView2 control and add it to the new tab
Dim newWebView2 As New WebView2()
newTab.Controls.Add(newWebView2)

‘ Set the properties of the new WebView2 control
newWebView2.Dock = DockStyle.Fill
newWebView2.Source = New Uri(“about:blank”)
newWebView2.AllowDrop = True

‘ Add an event handler for the Drop event of the new WebView2 control
AddHandler newWebView2.DragDrop, AddressOf WebView2_DragDrop

‘ Select the new tab
TabControl1.SelectedTab = newTab
End Sub
“`

This code initializes the WebView2 control, creates a new tab and adds it to the TabControl, creates a new WebView2 control and adds it to the new tab, sets the properties of the new WebView2 control, adds an event handler for the DragDrop event, and selects the new tab.

Note that the `WebView2_DragDrop` event handler referenced in the code has not been implemented yet. We will add that code in the next step.
lets add the dragdrop event
Sure! Here’s how you can add the `WebView2_DragDrop` event handler to your code:

“`vb.net
Private Sub WebView2_DragDrop(sender As Object, e As DragEventArgs)
‘ Get the URL that was dropped onto the WebView2 control
Dim url As String = TryCast(e.Data.GetData(DataFormats.Text), String)

‘ If a URL was dropped, navigate to it in the WebView2 control
If Not String.IsNullOrEmpty(url) Then
Dim webView As WebView2 = DirectCast(sender, WebView2)
webView.CoreWebView2.Navigate(url)
End If
End Sub
“`

This code gets the URL that was dropped onto the WebView2 control, navigates to that URL if one was dropped, and does nothing if no URL was dropped.

Now that we have added the `WebView2_DragDrop` event handler, the `Form1_Load` sub should contain the following code:

“`vb.net
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
‘ Initialize the WebView2 control
WebView2.EnsureCoreWebView2Async(Nothing)

‘ Create a new tab and add it to the TabControl
Dim newTab As New TabPage()
TabControl1.TabPages.Add(newTab)

‘ Create a new WebView2 control and add it to the new tab
Dim newWebView2 As New WebView2()
newTab.Controls.Add(newWebView2)

‘ Set the properties of the new WebView2 control
newWebView2.Dock = DockStyle.Fill
newWebView2.Source = New Uri(“about:blank”)
newWebView2.AllowDrop = True

‘ Add an event handler for the Drop event of the new WebView2 control
AddHandler newWebView2.DragDrop, AddressOf WebView2_DragDrop

‘ Select the new tab
TabControl1.SelectedTab = newTab
End Sub

Private Sub WebView2_DragDrop(sender As Object, e As DragEventArgs)
‘ Get the URL that was dropped onto the WebView2 control
Dim url As String = TryCast(e.Data.GetData(DataFormats.Text), String)

This code should allow you to drag and drop a URL onto a WebView2 control and navigate to that URL in a new tab.
Imports Microsoft.Web.WebView2.WinForms

Public Class Form1
Private Sub TabPage1_Click(sender As Object, e As EventArgs) Handles TabPage1.Click

‘ Create a new tab and add it to the TabControl
Dim newTab As New TabPage()
TabControl1.TabPages.Add(newTab)

‘ Create a new WebView2 control and add it to the new tab
Dim newWebView2 As New WebView2()
newTab.Controls.Add(newWebView2)

‘ Set the properties of the new WebView2 control
newWebView2.Dock = DockStyle.Fill
newWebView2.Source = New Uri(“about:blank”)
newWebView2.AllowDrop = True

‘ Add an event handler for the Drop event of the new WebView2 control
AddHandler newWebView2.DragDrop, AddressOf WebView2_DragDrop

‘ Select the new tab
TabControl1.SelectedTab = newTab
End Sub

Private Sub WebView2_DragDrop(sender As Object, e As DragEventArgs)
Dim link As String = e.Data.GetData(DataFormats.Text)
Dim newTab As New TabPage(link)
Dim newWebView2 As New Microsoft.Web.WebView2()
newWebView2.Dock = DockStyle.Fill
newWebView2.Tag = link
newWebView2.Source = New Uri(link)
newTab.Controls.Add(newWebView2)
TabControl1.TabPages.Add(newTab)
End Sub

‘ Step 7

Note that the `TabControl1_SelectedIndexChanged` event

Error BC30456 ‘Volume’ is not a member of ‘WebView2’.

The `WebView2` control doesn’t have a `Volume` property, which is why you’re getting an error. Instead, you can use the `CoreWebView2` property to access the underlying `CoreWebView2` object and set the volume using its `AudioVolume` property.

Here’s the updated `VolumeControl_Scroll` method with the changes:

“`vb
Private Sub VolumeControl_Scroll(sender As Object, e As EventArgs)
Dim selectedTab As TabPage = TabControl1.SelectedTab
Dim webView2 As WebView2 = selectedTab.Controls.OfType(Of WebView2)().FirstOrDefault()
Dim volumeControl As TrackBar = TryCast(sender, TrackBar)
If webView2 IsNot Nothing AndAlso volumeControl IsNot Nothing Then
webView2.CoreWebView2.AudioVolume = volumeControl.Value / 100.0F
End If
End Sub
“`

It looks like you are trying to access a member called `AudioVolume` that belongs to the `CoreWebView2` class, but you are trying to access it through the `WebView2` class. To fix this error, you can try changing `webView2.CoreWebView2.AudioVolume` to `webView2.AudioVolume`. The `AudioVolume` property should be a member of the `WebView2` class.
can we use the CoreWebView2 class or create it?

The `CoreWebView2` class is part of the WebView2 runtime and is created automatically when you initialize the `WebView2` control.

In your code, you can access the `CoreWebView2` instance by calling the `WebView2.CoreWebView2` property. For example, to set the audio volume, you can use:

“`vb.net
webView2.CoreWebView2.AudioVolume = volume
“`

where `webView2` is an instance of the `WebView2` control and `volume` is a float value between 0 and 1.
