设置窗体颜色渐变，了解窗体颜色的设置。（基于对话框编程）-Setting form color gradient to understand the form the color settings. (Based on Dialog Programming)

基于MFC对话框的编程：一个动态的渐变的椭圆形对话框。-MFC dialog-based programming: a dynamic gradient of the oval-shaped dialog box.

GDI+的应用使得平面图形图象编程变的更加容易，本文以一个基于对话框的时钟程序为例，在VC6.0中调用*.png图片实现半透明渐变窗口，该程序实现了指针式和数字式两种时钟显示方式。窗口实现了半透明渐变窗口、窗口拖动无移动矩形框、隐藏了任务栏窗体按钮等。-GDI+ application programming graphic image makes the plane easier to change, this clock is a dialog-based program, for exam
