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".

From Windows CE API Reference:

This API is part of the complete Windows CE OS package as provided by Microsoft. The functionality of a particular platform is determined by the original equipment manufacturer (OEM) and some devices may not support this API.

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 );
