Common Dialog Box in WinCE (evc++ API)

Hi People,

I'm trying to load a common dialog box on a Pocket PC, but my Common Dailog fails to load. when i call the GetLastError function it display 120 what does this mean???

I have list my code below so that you can get a better understand

      int rnet;
      OPENFILENAME ofn;
      TCHAR szFile[MAX_PATH+1] = {0};
      memset(&ofn, 0, sizeof(ofn));
      // Fill out data structure
      ofn.hInstance         = GetModuleHandle(NULL);
      ofn.lpstrCustomFilter = 0;
      ofn.lpstrInitialDir   = 0;
      ofn.lStructSize = sizeof(ofn);
      ofn.lpstrFilter = TEXT("Image Files (*.Log)\0*.log\0All Files (*.*)\0*.*\0");
      ofn.lpstrFile = szFile;
      ofn.nMaxFile = MAX_PATH;
      ofn.lpstrTitle = TEXT("Open Squeak image ...");
      ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
      ofn.lpstrDefExt = TEXT("image");
      ofn.hwndOwner = hDlg;

      // Show dialog
      if (!GetSaveFileName(&ofn))
      {
                   rnet = GetLastError();
            Printf(L"Failed to Display Dialog BOX");
            Printf(L"GetLastError = %d",rnet);
            return FILE_ERROR;
      }

      return FILE_OK;

120 means "This function is not supported on this system".

Here is an old example of how to use Formatmessage. Notice it uses GetLastError(); This may help you in determining other errors you run into.

Although with CE I do not know if it will work because of the limmitted API.

RJ

LPVOID lpMsgBuf;
FormatMessage(
FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_SYSTEM |
FORMAT_MESSAGE_IGNORE_INSERTS,
NULL,
GetLastError(),
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
(LPTSTR) &lpMsgBuf,
0,
NULL
);

// Process any inserts in lpMsgBuf.
// ...
// Display the string.
::MessageBox( NULL, (LPCTSTR)lpMsgBuf, "Message is...", MB_OK | MB_ICONINFORMATION );
// Free the buffer.
LocalFree( lpMsgBuf );
