How to dsiplay next image on dialog by using Direct Draw


I am displaying BMP on dialog window  by using DirectDraw. I am trying to show next image after i click the mouse. After i click the mouse next image is displaying, but it is on first image.  How can i remove the first image after the next image loads. First image i am calling in OnInitDialog() function. And the next images are calling in Mouse event finction.

Thanking you.
