Re: Progress Dialog Box

Hi All,

  I'm very new to VC++ , MFC programming. I have a Button in a
property page. On clicking this button i want a "Progress Dialog Box"
to pop up and run as a seperate thread. The problem is i'm not able to
see the "Progress Dialog Box" and the application goes to hang state.
Please help.

Here's the part of the code..

********** In the property page*******************

void FlashDlg::OnDownloadButton()
{

abort_flag = FALSE;
thread_finished_flag = FALSE;

cpd.Create( );

CWinThread * dl_thread = AfxBeginThread(::DownLoadFunction, this);//
Start downloading thread

while (thread_finished_flag == FALSE)
if (cpd.CheckCancelButton()) abort_flag = TRUE;

AfxMessageBox(result_str);

}

UINT DownLoadFunction(LPVOID lParam)
{
FlashDlg * p = (FlashDlg *)lParam;

p->cpd.SetUpper(25);

for(int i=0 ; i < 25 ; i=i+2)
{
p->cpd.SetPos(i);
Sleep(100);
}
p->thread_finished_flag = TRUE;
return 0;
}

***************** In the ProgressDialog*****************

BOOL CProgressDlg::Create(CWnd *pParent)
{
   // Get the true parent of the dialog

   m_pParentWnd = CWnd::GetSafeOwner(pParent);

   if((m_pParentWnd!=NULL) && m_pParentWnd->IsWindowEnabled())
   {
     m_pParentWnd->EnableWindow(FALSE);
     m_bParentDisabled = TRUE;
   }

   if(!CDialog::Create(CProgressDlg::IDD,pParent))
   {
     ReEnableParent();
     return FALSE;
   }

   return TRUE;
}
