Re: Toolbar doesn't react on first click.

Hello everyone. I create program with one toolbar and few CWnd objects =

in CFrameWnd. Only one window (CWnd) is shown at time. When I start =

action on this window (OnLButtonUp and OnlButtonDown) program makes =

expensive calculation, next he hides window (SW_HIDE), and shows =

(SW_SHOW). But sometimes when I make double-click on window, =

show OK, but toolbar freeze (doesn't react on first click and I must
click him once more). I try to override OnLButtonDblClk but my
application never goes in to. I thing the problem are messages that =

pushed to queue when program makes this calculation. I must fix this =

as fast as possible, so I try to override Run method. Before program
start calculation I set semaphore up, then I start calculation, clear
message queue, and after calculations semaphore goes down. I don't =

it is good solution anyway I probably making something wrong because
i.e. WM_SETFOCUS messages are still received by window even when
semaphore is up. Any help will be great. This is my override Run =

 
 
volatile bool someFocus = false;
// semaphore
volatile bool youCanPump = true;
 
int CDodaApp::Run()
{
  youCanPump = true;
  someFocus = false;
 
  if (m_pMainWnd == NULL && AfxOleGetUserCtrl())
  {
    // Not launched /Embedding or /Automation, but has
    no main window!
      TRACE0("Warning: m_pMainWnd is NULL in CWinApp::Run
          - quitting application.\n");
    AfxPostQuitMessage(0);
  }
  ASSERT_VALID(this);
 
  // for tracking the idle time state
  BOOL bIdle = TRUE;
  LONG lIdleCount = 0;
 
  // acquire and dispatch messages until a WM_QUIT message
  is received.
    for (;;)
    {
      if(youCanPump == true)
      {
        // phase1: check to see if we can do idle work
        while (bIdle && !::PeekMessage(&m_msgCur, NULL,
              NULL, NULL, PM_NOREMOVE))
        {
          // call OnIdle while in bIdle state
          if (!OnIdle(lIdleCount++))
            bIdle = FALSE; // assume "no idle" state
        }
 
        // phase2: pump messages while available
        do
        {
          if(m_msgCur.message == WM_SETFOCUS ||
              m_msgCur.message == WM_KILLFOCUS)
            someFocus = true;
 
          // pump message, but quit on WM_QUIT
          if (!PumpMessage())
            return ExitInstance();
 
          // reset "no idle" state after pumping
          "normal" message
            if (IsIdleMessage(&m_msgCur))
            {
              bIdle = TRUE;
              lIdleCount = 0;
            }
 
        } while (::PeekMessage(&m_msgCur, NULL, NULL,
              NULL, PM_NOREMOVE));
      }
      else
      {
        while(::PeekMessage(&m_msgCur, NULL, NULL, NULL,
              PM_REMOVE))
          if(m_msgCur.message == WM_SETFOCUS ||
              m_msgCur.message == WM_KILLFOCUS)
            someFocus = true;
      }
    }
  ASSERT(FALSE); // not reachable
