If u need an Open File Common Dialog, u can do this

          OPENFILENAME ofn;
            TCHAR  szFile[5000] = "\0";
          strcpy(szFile, "");

          memset(&ofn, 0, sizeof (ofn));
          ofn.lpstrFile          = szFile;
          ofn.lStructSize          = sizeof(OPENFILENAME);
          ofn.hwndOwner          = NULL;
          ofn.nMaxFile          = 5000;
          ofn.lpstrFilter          = "Text Files (*.txt)\0*.txt\0Document Files (*.doc)\0*.doc\0All Files (*.*)\0*.*\0\0";
          ofn.lpstrTitle          = "Open a File";
          ofn.lpstrDefExt         = "txt";
          //ofn.lpfnHook          = (LPOFNHOOKPROC)OFNHookProc1;
          ofn.lpfnHook          = NULL;

               if(NULL != ofn.lpstrFile)
                    // to do
