I have to navigate from one screen to another. The first dialog should appear for 30 seconds and then go to second dialog. How can i achieve this in MFC? If i use Sleep(30000)the desired result is not achieved.

Sleep(mlsec) will wait mlsec miliseconds before implementing next code, so it is not suitable for using in InitDialog and other message handlers.

More suitable is to use SetTimer(timerID,mlsec), which initializes the timer with ID=timerID. It sends WM_TIMER message to the window each mlsec. You can kill the timer using KillTimer(timerID).

How to use:


1. Add WM_TIMER Windows Message Handler to your window. This will add OnTimer(UINT nIDEvent ) function.

2. Add the code in it

  static int nRestTime = 1;

  if ( nRestTime-- == 0 )
  {
     KillTimer(nIDEvent);
//   And here add the code to
//   Destroy the first dialog
//   and create the second one
  }

3. Put
   
  SetTimer(1, 30000);

  into the window initialization function, where the first
  dialog is created. For example, If your first dialog
  is the main window, you can put it into its InitDialog
  function.
