Show wxDialog without taskbar/task switch icon from hidden wxFrame?

[Volker Bartheld]

Hi!

Subject says it all. As a kind of "progress notification" my app operates
a hidden wxFrame. Depending on its state, this frame shows a stacked pile
of "bare" dialogs growing from the right bottom of the screen. See below [1]
for some source code.

Problem is, that I can't keep the default icons from being shown in the task
switch popup (wxMSW, ALT-TAB) - 10 in case of the sample.

Is there a way to have a hidden app and show a window that is neither listed
in the taskbar nor with the task switch menu?

Any help appreciated.

Thanks in advance,
Volker

P.S.: No, I don't think this is a nice way to behave for an app either.
But as the design department wants it, I try to deliver...
