Textbox transparent in Remote Desktop

[Dale M.]

Greetings.

I have a WinForms app in VB.Net that opens a second form
via the ShowDialog() method. The controls (radio button,
textbox, frame lines, etc) all have their backgrounds
transparent when viewed through Remote Desktop. I have
tried just the Show() method, set the background for the
control explicitly to white, and still no joy. The
opacity for the form is set to the default 100%. It works
normally when run directly on a machine.

Has anybody else run into this or know how to fix it? It
is very difficult to read stuff when the form underneath
is showing through the controls.

Thanks.

It looks like the TransparencyKey got set somehow in my
dialog form. It was 224,224,224, which appears to be the
gray used in forms. Even though the form was set to 100%
opacity, it still messed up the controls. Getting rid of
that property for the form cleared it all up.
