WM_NCHITTEST消息问题【已解决】

我系统是xp,找了另一台xp也是这样
但在win7上试就没问题
这是为啥啊?郁闷。。。

哦，是的，没仔细看。

弄不懂啊...

还是不懂!.............

难道没人知道这到底是什么原因吗

我自己想到的解决办法就是不注册WM_NCHITTEST和WM_MOVING，但这样窗体就不能移动了，所以再放一个跟hGUI上的png图片一样大的透明label，当$CursorInfo[4]=label并且$CursorInfo[2]=1就用相应的代码去移动窗体。。。。。不过这样感觉不爽。。。蛋疼。。。

只注册WM_MOVING，_SendMessage($hGUI, $WM_SYSCOMMAND, $SC_MOVE + $HTCAPTION, 0)搞定
