That's great, Tobi. So then Martin can do something like: Dim hForm As Form Dim hControl As Control Dim hTextBox As TextBox If Panel1.Parent Is Form Then hForm = Panel1.Parent hControl = hForm.Controls["TextBox1"] If hControl Is TextBox Then hTextBox = hControl Print hTextBox.Text Endif Endif I tried it. It works. > As for the hijacking, my bad. But I didn't understand Martin's question > either way, so let's pretend I thought this was relevant to the thread :-) Lol.
