C# Conversion - AddressOf Delegate

I am looking for help converting the following block of C# code to VB.Net:

public static void CloseSplash()
{
frmSplash formSplash = SplashInstance();

if (formSplash.InvokeRequired)
formSplash.Invoke(new CloseDelegate(CloseSplash), null);
else
formSplash.Close();
}

I have used various C# to VB Converters... They return the following:

Public Shared Sub CloseSplash()
Dim FormSplash As frmSplash = SplashInstance
If FormSplash.InvokeRequired Then
FormSplash.Invoke(AddressOf CloseSplash, Nothing)
Else
FormSplash.Close()
End If
End Sub

However this code generates a " 'AddressOf' expression cannot be converted to 'System.Delegate' because type 'System.Delegate' is declared 'MustInherit' and cannot be created." error.

MSDN says I need to "Assign the AddressOf expression to a specific delegate type", but I guess I don't understand this Any pointers would be appreciated.

C# Conversion - AddressOf Delegate

johnconstantine

you need to declear a delegate

Public Class Form1

Private Delegate Sub CloseDelegate()

Public Shared Sub CloseSplash()

Dim FormSplash As frmSplash = SplashInstance

If FormSplash.InvokeRequired Then

FormSplash.Invoke(New CloseDelegate(AddressOf CloseSplash), Nothing)

Else

FormSplash.Close()

End If

End Sub

End Class

Already had the delegate declaration, however I did not have "New CloseDelegate" part in my FormSplash.Invoke statement. That took care of it. Thanks for your help!

Use a better C# to VB converter.

Adding the C# delegate declaration included in the original sample, we get the following from Instant VB:

Private Delegate Sub CloseDelegate()
Public Shared Sub CloseSplash()
Dim formSplash As frmSplash = SplashInstance()

If formSplash.InvokeRequired Then
formSplash.Invoke(New CloseDelegate(AddressOf CloseSplash), Nothing)
Else
formSplash.Close()
End If
End Sub
