Hi everbody,
          I have a handle of an icon(HICON) which i got using SHGetFileInfo. I want to save this handle as an Icon file(.ico). I am using following procedure:

int  SaveMyIcon( HICON hIcon)
{
  int       fh, i, iResult;
  UINT      uiSize;
  DWORD     dwSize;
  OFSTRUCT  of;
  LPSTR lpGMem;

    if (!hIcon)
      return FALSE;

    dwSize  = GlobalSize(hIcon);
    lpGMem  = (LPSTR)GlobalLock(hIcon);
    fh = OpenFile ("myicon.ico", &of, OF_WRITE | OF_CREATE);

    if (fh == -1)  // If NOT opened successfully.
    {
     MessageBox(NULL, "Unable to create file", NULL, MB_OK );
     return FALSE;
    }

    uiSize = _lwrite(fh, (LPSTR)lpGMem, (UINT)dwSize);
    _lclose(fh);

    if (uiSize == -1 || uiSize < (UINT)dwSize)
    {
       MessageBox(NULL, "Unable to read file", NULL, MB_OK );
      GlobalUnlock(hIcon);
       return FALSE;
    }
    else // Everything worked, return hGMem.
    {
      GlobalUnlock(hIcon);
      return TRUE;
    }
}


This procedure is not working. I am unable to create a ico file of the handle using the above procedure. How to save an icon file using the handle of an icon?

Thanks in advance.
