winform 如何屏蔽窗体双击事件

很简单吧！！把双击事件弄出来，里面写不会出现错误，有不会执行的东西就OK了，比如写一个不可能的判断句，赋值i=0判断在i==1时出提示框

把你窗体的FormBorderStyle改为FixedDialog试试

关键在于为什么双击之后你的窗体会移动，默认情况下它会移动吗，这是一个需要额外处理的行为。如果你指的是双击标题栏后窗体会放大的话，去掉标题栏就是了：form.FormBorderStyle=FormBorderStyle.None;

把窗体的MaxinizeBox和MixinizeBox设为false

继承的这个窗体类楼上朋友们说的不行呵呵不过还是谢谢你们

不会啊指教就是png透明效果图片哪里透明窗体就哪里透明
前辈急啊
我这个也是网上下的

        protected override void WndProc(ref Message m)
        {
          base.WndProc(ref m);
          if(m.Msg == 0x84 && m.Result == (IntPtr)2) // 不让拖动标题栏
          {
            m.Result = (IntPtr)1;
          }
          if (m.Msg == 0xA3)                         // 双击标题栏无反应
          {
            m.WParam = System.IntPtr.Zero;
          }
        }

重寫窗體雙擊事件，直接把裏邊的的base.ondoublick()屏掉就行了

B M W 是正解！
顶下！
