解决方案
解决方案二：
哎，粘了这么长的代码，不知道什么意思~！接分
解决方案三：
代码有点长了！你加点描述就好了！
解决方案四：
//SetWindowLong(newHandleRef(this,this.Handle),-16,GetWindowLong(newHandleRef(this,this.Handle),-16)|WS_SYSMENU);//这里加上这段后下面的caseWM_NCHITTEST:就没反应了请问这儿怎么写这段有问题
解决方案五：
[DllImport("user32.dll")]publicstaticexternboolReleaseCapture();[DllImport("user32.dll")]publicstaticexternboolSendMessage(IntPtrhwnd,intwMsg,intwParam,intlParam);publicconstintWM_SYSCOMMAND=0x0112;publicconstintSC_MOVE=0xF010;publicconstintHTCAPTION=0x0002;privatevoidbutton1_MouseDown(objectsender,MouseEventArgse){ReleaseCapture();SendMessage(this.Handle,WM_SYSCOMMAND,SC_MOVE+HTCAPTION,0);}
这是无边框拖动
解决方案六：
发的东西很好很完整放到VS2008里新建一个窗体就行了就能看到是什么意思就是//SetWindowLong(newHandleRef(this,this.Handle),-16,GetWindowLong(newHandleRef(this,this.Handle),-16)|WS_SYSMENU);//这里加上这段后下面的caseWM_NCHITTEST:就没反应了请问这儿怎么写这段有问题把注释去掉就不能响应caseWM_NCHITTEST:的功能了
解决方案七：
hhc123你的我试过了不好用privatevoidForm12_MouseDown(objectsender,MouseEventArgse){ReleaseCapture();SendMessage(this.Handle,WM_SYSCOMMAND,SC_MOVE+HTCAPTION,0);}
解决方案八：
接分，接分，接分，接分，
解决方案九：
解决方案十：
学习。。。
解决方案十一：
有没有牛人可以解决这个问题啊？急！！！呵呵~
解决方案十二：
同求答案。。加上任务栏左右键功能后不能改变大小，可以改变大小的时候却不能使用任务栏左右键功能。。
