只要条件成立就SHOW出一个消息框，可是不知怎么的SHOW出两个。
还有从论坛上下载的皮肤控件有个毛病，就是PictureBox控件有图的情况下不能更改皮肤。所以我就SHOW消息框。

以下是引用pacocai在2007-9-13 5:14:27的发言：
还有就是你说的PictureBox控件有图的情况下不能更改皮肤。这个情况我也没发现，我这里PictureBox有图的情况下一样能更换皮肤。你还是先找你机子的原因吧……因为现在发的这个皮肤控件确切的说是商业版的。这种问题通常不太可能会出现。

我试了，有图的情况下确实可以。不过我按你说的更改了代码Message窗口还是出现两个，有图也不能换肤。
我把项目打包发上来你帮我看看！
