As I wrote in this thread (which wasn’t fully answered)

we have a problem with our Dialog based application, that uses a wide range of the ProfUIS controls. As mentioned in the above thread, all other controls work, except when I press a CExtButton. The app hangs, and when I pause debugging, it sits at the CWinApp::PreTranslateMessage

This is the debug call stack:

The issue is not present with 2.83, only with 2.84 and 2.85.

The project is ported to using ProfUIS, and ProfUIS is not installed on my computer, I use the source files and the libs (ymd-libs) I built using the workspaces provided with the full source code.

Best regards,

Is it possible to create a stripped version of your project with UI code only that reproduces this issue?

Carsten Pedersen Jun 17, 2009 - 1:00 AM

We will try to strip the project down as much as possible. Where should I send the zip?

Carsten Pedersen Jun 16, 2009 - 2:09 AM

I can inform you that we have a dialog class that contains a CExtTabWnd. Inside each tab is a child dialog that is created runtime. It is inside this child dialog that the CExtButton resides.

Best regards
