Hey Friends

Any idea of how i can draw a text using CDC with Transparency / Opacity ?

Something like Watermarking[^] in MFC ?

On Windows there is option of making Windows Alpha Blend / Transparent using something like
static PSLWA pSetLayeredWindowAttributes = NULL;
static BOOL initialized = FALSE;

BOOL MakeWindowTransparent(HWND hWnd, unsigned char factor)
   /* First, see if we can get the API call we need. If we've tried
    * once, we don't need to try again. */
   if (!initialized)
      HMODULE hDLL = LoadLibrary ("user32");
      pSetLayeredWindowAttributes = 
         (PSLWA) GetProcAddress(hDLL, "SetLayeredWindowAttributes");
      initialized = TRUE;
   /* ... elided ... */

Is there any related way for Text ?
