download progress (threads)

hi there..

i have a function in my Dialog-based MFC app that checks for updates

void CExDlg::CheckForUpdates()
{
      //...
      //pUpdateDlg is the child dialog has the progress bar

      for (int x = 0; x < num_updatedfiles; x++)
      {
            //function that downloads the updated file
            m_Ftp->GetFile(strFile[x], strFile[x], FALSE, ...);
            pUpdateDlg->m_MyProgressBar.SetPos(x); //<==
      }
}

well problem is =\ the progress bar doesn't move (the whole dialog doesn't refresh) so i'm gonna have to use Threads so the progress bar moves after each file download.

i don't know much about how to use um.. anyone got any ideas?

tried using the ones on CodeProject but i guess i'm just a newbie n dunno how to use them =p

pUpdateDlg->m_MyProgressBar.SetPos(x); //<==
pUpdateDlg->UpdateWindow(); //force it to redraw

tried that before, AndyAinscow, didn't work =(

and, not really sure what the DoEvent() function does, AlexFM, but it works GREAT! =p

Thanks both of you =)

DoEvents handles all Windows messages in the queue, including WM_PAINT. This is a reason dialog is redrawn. Without DoEvents messages remain in queue and handled only when function CheckForUpdates exits.

AndyAinscow

Your right. I had a look at an older app that had exactly the same probelm with a prgress control. I forgot I had a fn to do what Alex suggested in it.
