Collage

Collage is a little game that let users to rearrange pictures according to the given order. The main logic is as follows:
void canvasFrame::OnLButtonDown(UINT nFlags, CPoint point) 
{
    CClientDC dc(this);
    xx = yy = -1;

    //判断鼠标点击的位置
    if(point.x > 0 && point.x < 100)
    {

if(point.y > 0 && point.y < 100)
        {
            xx = 0;
            yy = 0;
        }
        if(point.y > 100 && point.y < 200)
        {

        }
        if(point.y > 200 && point.y < 300)
