}




an example usage of this class:    

CMFileDlg dlgFile(TRUE);
     CString strPath = GetDocument()->GetPathName();
     int start = strPath.ReverseFind('\\') + 1;
     CString strDir( strPath.Left(start) );
     dlgFile.m_ofn.lpstrTitle = strTitle;
     dlgFile.m_ofn.lpstrInitialDir = strDir;
     dlgFile.m_ofn.lpstrDefExt = "bmp";
     dlgFile.m_ofn.lpstrFilter = "Bitmap Files (*.bmp)\0*.bmp\0Gif Files (*.gif)\0*.gif\0Jpeg Files (*.jpeg)\0*.jpeg\0All Files (*.*)\0*.*\0\0";
     dlgFile.m_ofn.hwndOwner = AfxGetMainWnd()->GetSafeHwnd(); //in case of MDI/SDI application only

     if ( dlgFile.DoModal() != IDOK )
          return;


cheers

Sorry, some of that stuff

if(ext!="MAS" && ext!="EST")

didn't belong. I used that for my code, but I didn't mean to copy it in. The general idea is still right though. Simply change the "MAS" or "EST" to be whatever you filtered the dialog for.

gar,

you may reject tvanceplus's answer and post your code so we can tell you what's wrong with your code.
