I’m using a modeless CExtResizableDialog and want to float it over other application (such as Excel) to drag and drop data.  I’m using this call:

      SetWindowPos(&wndTopMost, 0, 0, 0, 0, SWP_NOMOVE|SWP_NOSIZE);

This worked fine when I derived from CDialog but doesn’t work with CExtResizableDialog

We can create some test project which invokes the same line of code, but we would like not to guess how your real project really created dialog, which window styles are used by this dialog and so on. Could you please modify some simple Prof-UIS sample project like SDI, make it displaying dialog like your real project do and send this modified project to us.

I created different projects using variations of ProfUIS/non-ProfUIS dialogs and found that the problem isn’t related to your library.  Unfortunately I haven’t figured out what IS causing it.

After a long struggle...

The problem is caused by something the toolbar does AFTER sending the command.  In processing the command, I use SetWindowPos() to make it topmost.  But sometimes it works, sometimes it doesn’t.

My work-around was to post another message to the window.  The toolbar command processing then completes before I get the 2nd command message.  When I process the 2nd command message, I call SetWindowPos() and everything works fine.

CDlg::OnBtnFloat()
{
PostMessage(WM_COMMAND, ID_BTN_FLOAT2);
}
CDlg::OnBtnFloat2()
{
SetWindowPos(...);
}
