　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 makes the plane graphic images become easier, this paper, a dialog-based clock program as an example, VC6.0 call*. png image to achieve gradient translucent window, the program achieved a pointer two kinds of clocks and digital display. Achieved a translucent window, gradient window, drag the window without moving a rectangular box, hide the taskbar buttons and so on form.
