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

对话框功能实现画图板功能，可以绘制直线，矩形，三角形的等不同形状不同颜色的图形，可以拖动，支持清空换背景。-The dialog features drawing board, you can draw lines, rectangles, triangles of different shapes in different colors graphics can drag support empty for background.

这是JAVA写的画图板，建立输入输出流、按钮数组，存放以下名称的功能按钮、创建基本操作按钮，定义铅笔画，也就是用鼠标拖动着随意绘图、绘制以指定颜色填充的实心矩形、实心椭圆、指定颜色填充的实心圆角矩形、橡皮擦-This is written in JAVA drawing board, the input and output streams, button array storage following the name of the function button to create a ba

这个多文档程序能实现在多文档界面中用鼠标的拖动来画矩形-This multi-document program can achieve in a multi-document interface using the mouse and drag to draw a rectangle
