这个是个公共模块。但是图片是固定在资源文件里面，还没有想到其他办法，
如果有谁想到其他解决方法，请告诉我，大家可以互相学习哦。^_^
其中：
'LoadResPicture(101,
0).Handle
是资源文件中ID为101的图片。
也可以换成某个窗体的图片框中的图片。
例如：Form1.Picture1.Picture.Handle

Answer 2

自己做个form窗口来调用比较好。。。

追问

关键是我有好多这个，而且我已经做完了，就差修改颜色了。

追答

你只需要重新弄个窗体，然后修改调用的语句而已，工作量不会很大的，找其他办法更加麻烦。
可以用查找功能来定位这些要修改的语句。
