Developer Studio does this when loading a project. You can implement this by using CStatusBar and CProgressCtrl. MORE INFORMATION ================ A default AppWizard-generated MFC application has a class (CMainFrame) that contains a member variable m_wndStatusBar of type CStatusBar. The following sample code uses this member variable as the parent of a CProgressCtrl, which will be positioned over the first pane of m_wndStatusBar. First, the CProgressCtrl is created. Then, the sample code simulates a lengthy process using the Sleep function in a for loop. Sample Code ----------- /* Compile options needed: default */ // This is a menu option handler that takes a long period of time void CMainFrame::OnLengthyProcess() { // Create the CProgressCtrl as a child of the status bar positioned // over the first pane. RECT rc; m_wndStatusBar.GetItemRect (0, &rc); CProgressCtrl wndProgress; VERIFY (wndProgress.Create(WS_CHILD | WS_VISIBLE, rc, &m_wndStatusBar, 1)); wndProgress.SetRange(0, 50); wndProgress.SetStep(1); // Perform some lengthy process, simulated here with a for loop // and the Sleep function. for(int i=0;i<50;i++) { Sleep(50); wndProgress.StepIt(); } } Additional query words: ====================================================================== Keywords : kbMFC _IK11590 kbStatBar KbUIDesign kbVC400 kbVC500 kbVC600 kbGrpDSMFCATL kbMFCCtrlBar Technology : kbAudDeveloper kbMFC Version : :4.0,5.0,6.0 Issue type : kbhowto ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
