拖动winform无边框
作者:互联网
当winForm窗体FormBorderStyle属性改为None时,winForm窗体就会变成无边框。但此时会出现鼠标无法拖动winForm窗体现象,这个时候添加以下代码和事件就能恢复正常,具体代码如下:
[DllImport("user32.dll")]
public static extern bool ReleaseCapture();
[DllImport("user32.dll")]
public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);
private const int VM_NCLBUTTONDOWN = 0XA1;
private const int HTCAPTION = 2;
private void Form_MouseDown(object sender, MouseEventArgs e) //窗体事件(鼠标按下按钮时发生)
{
ReleaseCapture();
SendMessage((IntPtr)this.Handle, VM_NCLBUTTONDOWN, HTCAPTION, 0);
}
