    Help With Rectangle,

    as some of you might already know I am learning programming on my own for now, I've bumped into the function that draws a rectangle (I think) but I don't know how to implement it.......could anybody please show me an example of it?


    This is all the book says.......

    BOOL Rectangle ( HDC hdc, int nleftrect, int ntoprect, int nrightrect, int nbottomrect );

    return nonzero on failure.....



    could you please show me an example of how this could be used on a win32 program?

    After the window is passed the WM_PAINT message have the window do something similar to the following:

    PAINTSTRUCT ps;
    HDC hDc;
    HPEN hpen;

    hDc=BeginPaint([handle of window to draw to], &ps);
    //Create a pen to draw with
    hpen=CreatePen(PS_SOLID, 1, RGB(0,0,0));
    //Select pen into the device context
    SelectOjbect(hDc, hpen);
    //draw the rectangle (using current pen)
    Rectangle(hDc, 0, 0, 25, 25);
    ......
    EndPaint([window handle], &ps);
    DeleteObject(hpen);

    Hope this helps.
