    You coud define a RECT and blt (whichever blt method you prefer) your button pic there. Then on WM_LBUTTONDOWN assign the current mouse coord's to a POINT and if the user clicks, use PtInRect to check to see if they clicked on your button. To add "realism" to it, you can have a pic of multiple stages of your button. So for instance when the mouse moves over your button but they haven't clicked, a highlighted button pic will be displayed (reset if the mouse isn't over the button), and another pic to blt when they click to show a "pushed" state.

    I haven't messed with MFC very much, but here's a way to create a simple button:

    Code:
    //in your global declares
    HWND Btn1=NULL;
    
    //in your message handler
    
     //Create the Button
     //in this case "hwnd" is the HWND param passed to your
     //message handler, and "hInstMain" is the hInstance of your
     //parent window.
    case WM_CREATE:
     Btn1=CreateWindow(0,"Button","Button 1",WS_CHILD |
    WS_VISIBLE | BS_DEFPUSHBUTTON,10,10,100,30,hwnd,NULL,
    hInstMain,NULL);
    
    //See if the button was pushed
    case WM_COMMAND:
     if((HWND)lParam==Btn1)
      { 
          //your function goes here
       }
    This will create a standard Window's push button.

    To do it the
    way that I described earlier, you would define a RECT that would
    cover the area that your button covers. Then in your message
    handler check for cursor movement (WM_MOUSEMOVE). Then use
    the cursor coords ((LOWORD)lParam=x,(HIWORD)lParam=y) and
    put these into your POINT structure. Then use PtInRect to see if
    the POINT structure is within the RECT structure. If so, highlight
    the button.

    To check for mouse clicks use the same method except instead
    of checking with WM_MOUSEMOVE you'd check with
    WM_LBUTTONDOWN, etc..

    Also a non MFC jockey, but I do know MFC provides a CBitmapButton class which may well do what you want.

    Thanks for the back-up, Adrian.

    :: hides in shame at my lack of MFC knowledge ::

    monkeymon, sorry if my examples don't help. As I said I have
    very little experience with MFC. If either of my examples aren't
    what you're looking for I'll search for some good MFC
    CBitmapButton tutorials/articles and post the links.

    >>> :: hides in shame at my lack of MFC knowledge ::

    Nothing to be ashamed of. I bought Jeff Prosise's MFC bible as a little gift to myself the Christmas before last, and have read the first three chapters!

    It is supposedly the definitive work, but it is an MS book. "Programming Windows with MFC" make sure you have the second edition.

    I recently finished that book and I liked it alot. Although I dont think it is a great book if you are a beginer in Mfc. I would rather recomend "Teach yourself VC++ in 21 days" because in that book you write apps from the first page. The Prosise's book is the true Mfc bible and it is open on my desk 90% of the time I program, a great reference.
