高手请进！在list box插入并显示bmp图片

[chenping198]

问题描述：
dialog中有两个list box控件，两个button，四张bmp图片（自己截的图，存放在工程同个目录下的）。
将实现的功能：
当点击button1时，list box1和list box2中分别显示图片1、图片2；点击button2时，list box1和list box2中显示图片3和图片4。

请教：如何实现以上功能？请给出具体的实例及代码，谢谢

建立两个自绘的列表框，初始化时向两个列表框中分别加入一项字符串。当单击按钮时，设置位图ID到列表框项目上的数据,然后刷新列表框来重绘。
#define ID1 4
#define ID2 5
#define BTNID 123
#define BTNID1 124
