我的代码如下，可就是生成后没有办法移动
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private Point mouseOffset;
private bool isMouseDown = false;
private void Form1_Load(object sender, EventArgs e)
{
button1.Text = "X";
}
private void Form1_MouseDown(object sender,System.Windows.Forms.MouseEventArgs e)
{
int xOffset;
int yOffset;
if (e.Button == MouseButtons.Left)
{
xOffset = -e.X - SystemInformation.FrameBorderSize.Width;
yOffset = -e.X - SystemInformation.CaptionHeight - SystemInformation.FrameBorderSize.Height;
mouseOffset = new Point(xOffset,yOffset);
isMouseDown = true;
}
}
private void Form1_MouseMove(object sender,System.Windows.Forms.MouseEventArgs e)
{
if(isMouseDown)
{
Point mousePos = Control.MousePosition;
mousePos.Offset(mouseOffset.X,mouseOffset.Y);
Location = mousePos;
}
}
private void Form1_MouseUp(object sender,System.Windows.Forms.MouseEventArgs e)
{
if(e.Button==MouseButtons.Left)
{
isMouseDown = false;
}
}
private void button1_Click(object sender, EventArgs e)
{
this.Close();
}
}
}

大神快来~

xOffset = -e.X - SystemInformation.FrameBorderSize.Width;
yOffset = -e.X - SystemInformation.CaptionHeight - SystemInformation.FrameBorderSize.Height;
两个e.x ？

Point p;
mousedown leftbutton
p=e.location
mousemove leftbutton
设置窗体Location=Control.MousePosition向左上角平移p

2.重写WinProc
截获WM_LButtonDown消息
然后RelaseCapture
接着SendMessage()
WM_SYSCOMMAND
wParam SC_MOVE+HTCAPTION
lParam 0

方便一点你就在点击窗体空白处时算个坐标偏移值出来，然后加上去location属性既可，麻烦点就要考虑一下标题栏的矩形区域。

加上一句this.refresh试试

打开方式不对？

混脸熟！

public class NoBorderMove

control.MouseDown += new MouseEventHandler(MouseDownHandler);

}
private void MouseDownHandler(object o,MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
this._mouseIsDown = true;
this._x0ffset = e.X;
this._yOffset = e.Y;
}
}
private void MouseMoveHander(object o, MouseEventArgs e)
{

{

private void MouseUpHandler(object o, MouseEventArgs e)

正好写过这个，把这个对象New出来就可以了

搜索
[DllImport("user32.dll")]
public static extern bool ReleaseCapture();
[DllImport("user32.dll")]
public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);

Point point; //定义变量存储坐标值
//鼠标指针在组件上方并按下鼠标按钮时引发事件
private void FrmRegister_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left) //如果获取鼠标左键按下
{
Point pt = new Point();
pt = MousePosition; // 获取鼠标指针坐标
pt.Offset(point); //把组件移到指定坐标位置
this.Location = pt;
}
}
//鼠标指针移过组件时引发事件
private void FrmRegister_MouseDown(object sender, MouseEventArgs e)
{
point = new Point(-e.X, -e.Y); //记录鼠标指针移过的坐标
}

就像截图里一样，最好是在窗体上方添加一个Panel控件，大小控制在窗体上面和关闭那些按钮相同宽度的地方，两个代码引发事件加载到Panel控件的属性里，不要直接选择在窗体的属性，这样可以和有边框的时候一样，只有单击窗体上方（也就是panel控件的范围）才可以移动

[DllImport("user32.dll")]
public static extern bool Rese();
protected override void WndProc(ref Message m)
{
switch (m.Msg)
{
case 0X84:
base.WndProc(ref m);
if (m.Result == (IntPtr)0X1)
{
m.Result = (IntPtr)2;
return;
}
break;
}
base.WndProc(ref m);
}
加在构造函数前面。

我是不是发现错别字了！

你可以不同意我的观点，但我有揍你的权利。
