Hi, I have an application that does long processing and shows that progress in a progress bar in the statusbar area. Everything works and get's updated until I "Alt+Tab" to an other application while processing continues. When I switch back to my processing application, the progress bar or the whole client area doesn't get updated until the processing is complete? How can I force the screen update within the loop? I have tried following without any luck: --- ((CMainFrame*)AfxGetMainWnd())->m_wndProgCtrl.RedrawWindow(NULL, NULL, RDW_INVALIDATE | RDW_UPDATENOW | RDW_ERASE | RDW_ALLCHILDREN); ((CMainFrame*)AfxGetMainWnd())->RedrawWindow(NULL, NULL, RDW_INVALIDATE | RDW_UPDATENOW | RDW_ERASE | RDW_ALLCHILDREN); --- Any suggestions? |

Hi, This "makes more" than just a window update happening  .Hope there would be a method to just force the current view to be re-freshed during the run.... This is a database app that processes in a loop "something" and updates the progressbar when progressing... |

Hi, At the moment I don't want to start learning threading implementations. I'm fine with the current, except that the window update problem. It should be solvable somehow without threads. Sorry my ignorance but what the "ftw" stands for? |

ftw = "for the win".
From experience I know that a progress bar cannot be updated when performing CPU intensive operations unless you run the lengthy operation in another thread!
I've posted this link before. You should read it!
