Thread: Get a string from a modal dialog box

Hi,
I have a dialog based application. I want to pop up a little dialog box asking for a serial number before starting the main application. I used the following code in the constructor of the main dialog window:

Code:

CDialog serialDlg(IDD_SERIAL);

	// Create and show the dialog box
   INT_PTR nRet = -1;
   nRet = serialDlg.DoModal();
CString newValue;
	

   // Handle the return value from DoModal
   switch ( nRet )
   {
   case -1: 
      AfxMessageBox("Dialog box could not be created!");
      break;
   case IDABORT:
      // Do something
      break;
   case IDOK:
      m_serial.GetWindowText(newValue);
      break;
   case IDCANCEL:
      // Do something
      break;
   default:
      // Do something
      break;
   };

DDX_Control(pDX, IDC_EDITSERIAL, m_serial);

m_serial is a CEdit variable in my main dialog class.
Alas it is giving me an exception error. Anybody would know how to go about doing that. Thanks

Try moving that code from the constructor to the WM_INITDIALOG message handler.
