MFC/C++ Bring window to top no longer works

Question

I have a 32-bit application built on MFC/C++. It was ported from Visual C++ (6.0) to Studio 2015.

The application needs to come to the top when new data appears. On a couple of my customer systems the window does not come to the front as another application seems to want to stay on top. This code (in MainFrm.cpp) was working fine prior to the 2015 port (same "topmost" source code).

...

HWND hCurrWnd;
int iMyTID;
int iCurrTID;

hCurrWnd = ::GetForegroundWindow();
iMyTID   = GetCurrentThreadId();
iCurrTID = GetWindowThreadProcessId(hCurrWnd,0);

::AttachThreadInput(iCurrTID, iMyTID, TRUE);
::SetWindowPos(m_hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE);
::SetWindowPos(m_hWnd, HWND_NOTOPMOST, 0, 0, 0, 0, SWP_SHOWWINDOW | SWP_NOSIZE | SWP_NOMOVE);
::SetForegroundWindow(m_hWnd);
::SetFocus(m_hWnd);
::SetActiveWindow(m_hWnd);
::AttachThreadInput(iCurrTID, iMyTID, FALSE);

...

Is there another, more robust method for forcing a window to the top in MFC?

Answer 1

Use MFC functions direct, not the underlying WinApi. I tested this in Win10 with VS2019.

RESULT CMainFrame::OnNewDataReceived_UM( WPARAM wParam, LPARAM lParam )
{
    :  
    if (IsIconic())
        ShowWindow(SW_RESTORE);
    SetForegroundWindow();
    :
  } 

   returen TRUE;
}
