I have an MFC client application that is partly converted from a  Win32 SDK
based application. The application consists of several modeless and modal
dialogs.
To be able to handle dialogmessages (Tab-key, dialog accellerators etc.) a
global HWND (hWndCurrent) has been created. This HWND is set equal to the
current windows HWND (or NULL) in response to WM_ACTIVATE (in the non MFC
dialogs). In my CWinApp::PreTranslateMessage i call IsDialogMessage() using
hWndCurrent.
This works fine in all cases exept when i open a non MFC modal dialog
(DialogBoxParam() function). If the user switches to a modeless dialog when
the modal dialog is still open CWinApp::PreTranslateMessage is not called.
The result is that the Tab-key, dialog accellerators etc stops working for
the modeless dialog. When the user closes the modal dialog the Tab-key,
dialog accellerators etc work fine.
With MFC based modal dialogs there is no problem.

Will I have to rewrite every non MFC modal dialog or can someone help me
with this?

I use:
Visual C++ 5.0
MFC 4.21

You will have to override Run, but I suggest that you, even if the task
might be dreary, convert the dialogs. If they are developing, the
productivity gains in the future will be non-trivial - speaking from
experience of this kind of situation.
