Question

I want to upgrade an ActiveX control from VB6 to VB.NET. I’m having trouble upgrading this code:

If CanPropertyChange("Text") Then
    Text1.Text = Value
    RaiseEvent TextChange()
End If

I get the error: “Name ‘CanPropertyChange’ is not declared.“

Answer 1

VB.Net does not support anything similar to the CanPropertyChange(“Text”) method. The easiest way around this is to do the assignment within a Try…Catch block.

Try
  Text1.Text = Value
  RaiseEvent TextChange()
Catch ex As Exception

End Try

If the property cannot be written to an exception will be thrown which you can access in the Catch block.
