I have related question:

The code below works ok if when I draw transparent pict in the child window.
When I use it to draw pict on the menu it does not draw at all.

it is called like this:
 draw_transparent_picture_hwnd(lpdis->hwndItem, PICT_SAVE, &menu_rect, 
RGB(0, 128, 128));



void draw_transparent_picture(
     HWND hwnd,
     int  pictid,
     RECT *rct,
     COLORREF picture_background_color
     )
{
 BITMAP bitmap;
 COLORREF crOldBack   = 0;
 HDC dcImage     = NULL;
 HDC dcTrans     = NULL;
 HBITMAP pOldBitmapImage  = NULL;
 HBITMAP bitmapTrans   = NULL;
 HBITMAP pOldBitmapTrans  = NULL;
 HBITMAP hBitmap    = NULL;
 HDC hDC      = NULL;
 HDC hMemDC     = NULL;

 hDC = GetDC(hwnd);

 if ((hMemDC = CreateCompatibleDC(hDC)) == (HDC) NULL)
  return ;

 hBitmap = LoadBitmap(res_lib, MAKEINTRESOURCE(pictid));

 if (hBitmap == NULL)
  return ;

 crOldBack = SetBkColor(hDC, RGB(255, 255, 255));

 // Create two memory dcs for the image and the mask
 dcImage=CreateCompatibleDC(hDC);
 dcTrans=CreateCompatibleDC(hDC);

 // Select the image into the appropriate dc
 pOldBitmapImage = (HBITMAP)SelectObject(dcImage, hBitmap);

 // Create the mask bitmap
 GetObject(hBitmap, sizeof(BITMAP), &bitmap);
 bitmapTrans=CreateBitmap(bitmap.bmWidth, bitmap.bmHeight, 1, 1, NULL);

 // Select the mask bitmap into the appropriate dc
 pOldBitmapTrans = (HBITMAP)SelectObject(dcTrans, bitmapTrans);

 // Build mask based on transparent colour
 SetBkColor(dcImage, picture_background_color);
 BitBlt(dcTrans, 0, 0, bitmap.bmWidth, bitmap.bmHeight, dcImage, 0, 0, 
SRCCOPY);

 // Do the work - True Mask method - cool if not actual display
 BitBlt(hDC, rct->left, rct->top, bitmap.bmWidth, bitmap.bmHeight, dcImage, 
0, 0, SRCINVERT);
 BitBlt(hDC, rct->left, rct->top, bitmap.bmWidth, bitmap.bmHeight, dcTrans, 
0, 0, SRCAND);
 BitBlt(hDC, rct->left, rct->top, bitmap.bmWidth, bitmap.bmHeight, dcImage, 
0, 0, SRCINVERT);

 // Restore settings
 SelectObject(dcImage, pOldBitmapImage);
 SelectObject(dcTrans, pOldBitmapTrans);
 SetBkColor(hDC, crOldBack);


 DeleteDC (hMemDC);
 DeleteDC (dcImage);
 DeleteDC (dcTrans);

 ReleaseDC(hwnd, hDC);

}


Thank you
