VB.NET 控件移动
Public Class Form1Dim x As Double
Dim y As Double
Private Sub Form1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseClick
x = e.X
y = e.Y
Timer1.Enabled = True
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Button1.Left = x - (Button1.Width \ 2)
Button1.Top = y - (Button1.Height \ 2)
Timer1.Enabled = False
End Sub
现在控件可以移动到鼠标点击的位置，但是我想实现动画的那种效果，控件慢慢的移动到鼠标点击的位置，不要一下就移动过去，我要看移动的过程.

Public Class Form1
'鼠标点击时的坐标
Dim x1 As Integer
Dim y1 As Integer
''鼠标点击时button的坐标
Dim x2 As Integer
Dim y2 As Integer
Private Sub Form1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseClick
x1 = e.X
y1 = e.Y
x2 = Button1.Location.X
y2 = Button1.Location.Y
Timer1.Enabled = True
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If x1 < x2 Then
x2 -= 1
ElseIf x1 > x2 Then
x2 += 1
End If
If y1 < y2 Then
y2 -= 1
ElseIf y1 > y2 Then
y2 += 1
End If
Button1.Left = x2
Button1.Top = y2
If y2 = y1 AndAlso x2 = x1 Then
''到达目标地方,停止工作
Timer1.Enabled = False
End If
End Sub
End Class
改变x2,y2的变化规律可以得到不同的移动路线. --------------------编程问答-------------------- 先谢谢xingyuebuyu的回复 但是如果改变移动速度BUTTON 上下跳动 以前我写出过这个的 在timer计时器里用了两行代码 但是忘了算法 很模糊了 我写下
button1.left=button1.left+(x-(me.Width -button1.Width ))\2
button1.top=button1.top+(x-(me.Height -button1.Height ))\2
虽然写的不对 但是 就用了两行这样的代码 最后加上了
Timer1.Enabled = False
我会加分数 直到结贴 有多少分 送多少 送给回答正确的 --------------------编程问答--------------------

测试代码
Private Sub Form1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseClick
MoveTo(Button1, e.Location, 100, 2)
End Sub
--------------------编程问答-------------------- c.Left = l.X + i * xspeed
c.Top = l.Y + i * yspeed
不要用c.Left+=……去代替，因为Left是个整数，会导致移动速度的浮点被舍入，终点与目标点不吻合。 --------------------编程问答--------------------
就是这个了。 --------------------编程问答-------------------- Public Class Form1

学习了 --------------------编程问答-------------------- 举一个无边框窗体移动的例子
private Point mouseOffset; //坐标
private bool isMouseDown = false; //是否鼠标落下
public BaseForm()
{
InitializeComponent();
}
//窗体移动事件
private void BaseForm_MouseMove(object sender, MouseEventArgs e)
{
if (isMouseDown)
{
Point mousePos = Control.MousePosition;
mousePos.Offset(mouseOffset.X, mouseOffset.Y);
Location = mousePos;
}
}
//鼠标放下事件
private void BaseForm_MouseUp(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
