How can I make a modeless topmost for the desktop ?
-
I've got an application where I want a modeless dialog to stay on top of other applications. When I call SetWindowPos for the main window, this window stays on top of the others but when I try the same code for the modeless it just stay on top of its parent. The code is just basic SetWindowPos:
SetWindowPos(m_hWnd, NULL, 0, 0, 0, 0, HWND_TOPMOST);Is there a trick or a way to make that modeless topmost ? or is it a problem from my program ? :) Yarp http://www.senosoft.com/ -

You can se the *owner* of your dialog to be your main window... Iain.

Sure, this is a good idea. If I can't find a clean solution I will try this. Doesn't mean your solution is a dirty one, just looking for the perfect one if any ;) Yarp http://www.senosoft.com/

Try this instead. SetWindowPos(&wndTopMost, 0, 0, 0, 0, SWP_NOSIZE); CWnd::SetWindowPos[^]

void CfrmImg::EnableStayOnTop(bool bDesktop) { // Desktop topmost if (bDesktop) { ::SetWindowLongPtr(m_hWnd, GWL_HWNDPARENT, NULL); ::SetWindowPos(m_hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE); } // Application topmost else { if (::GetParent(m_hWnd)==NULL) ::SetWindowLongPtr(m_hWnd, GWL_HWNDPARENT, (LONG_PTR)frmMain->m_hWnd); ::SetWindowPos(m_hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE); } }I recall this is for a modeless dialog - don't know if it makes sense for modals. The SetWindowLongPtr with GWL_HWNDPARENT parameter is a dirty hack. MSDN says SetParent should be used instead, but with SetParent it didn't work (I presume I have to change the windows style as suggested by MSDN - this is a later clean up work). At the moment I'm happy with my stay on top function. Thanks all for your assistance. Yarp http://www.senosoft.com/
