Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
Dim sClassName As New StringBuilder("", 256)
'pass in the handle of the object for which to get
'the class name; for example, the form's handle
Call GetClassName(Me.Handle, sClassName, 256)
MessageBox.Show(sClassName.ToString)
End Sub
Alternative Managed API:
The ManagedWindowsApi project (http://mwinapi.sourceforge.net) provides a
class ManagedWinapi.SystemWindow that has a ClassName property.
