How to display CLabel transparent on picture control

C++

I would like to display the image files and some text ..
Actually I would like to make a tool for image-parody..

like that..
1. draw one back-ground image (User selectable)
2. draw some part foreground image
3. draw some text

so, I used cximage for drawing image because of variable-format image
and then for text, I used the CLabel class.

But CLabel not transparent..
if I didn't draw image, CLabel transparent..

Could you give a tip for me?
