Seth,

In VB.NET the following snippet code makes the form to be part of Excel:

Dim frm As New AboutBox1
Dim appWindow As New NativeWindow

Try

appWindow.AssignHandle(Process.GetCurrentProcess() .MainWindowHandle)
frm.ShowDialog(appWindow)
Catch ex As Exception
MessageBox.Show(ex.ToString, My.Application.Info.Title.ToString)
Finally
appWindow.ReleaseHandle()
End Try


Is this what You want?
