拖动窗体MOUSEUP怎么写
-------
不明白你要的是什么?拖动窗体,是移动窗体,还是高速大小,还是都是.
为什么要写MouseUp事件,而不用MouseMove或MouseDown事件呢?
------解决方案--------------------
//参考如下代码：
//客户区拖动窗体

[DllImport( "User32.DLL ")]
public static extern int SendMessage(IntPtr hWnd, uint Msg, int wParam, int iParam);
[DllImport( "User32.DLL ")]
public static extern bool ReleaseCapture();
public const uint WM_SYSCOMMAND = 0x0112;
public const int SC_MOVE = 61456;
public const int HTCAPTION = 2;

private void Form1_MouseDown(object sender, MouseEventArgs e)
{
ReleaseCapture();
SendMessage(Handle, WM_SYSCOMMAND, SC_MOVE | HTCAPTION, 0);
}
------解决方案--------------------
把如下代码粘入窗口试试:
internal static int WM_NCHITTEST = 0x84; //移动鼠标，按住或释放鼠标时发生的系统消息
internal static IntPtr HTCLIENT = (IntPtr)0x1;//工作区
internal static IntPtr HTCAPTION = (IntPtr)0x2; //标题栏
protected override void WndProc(ref Message m)
{
if (m.Msg == WM_NCHITTEST)
{
base.WndProc(ref m);
if (m.Result == HTCLIENT)
{
m.HWnd = this.Handle;

System.Drawing.Rectangle rect = this.RectangleToScreen(this.ClientRectangle);
Point C_Pos = Cursor.Position;
m.Result = HTCAPTION;//模拟标题栏,移动或双击可以最大或最小化窗体
}
}
else if (m.Msg == 0xa3)
{
return;
}
else
{
base.WndProc(ref m);
}
}
