如何实现鼠标步进移动?

[dylike]

想要实现鼠标指针从A点缓慢移动到B点,请问有何思路?

[wuyq11]

[DllImport( "user32.dll ", EntryPoint = "SetCursorPos ", CharSet = CharSet.Auto)]
static extern bool SetCursorPos(int X,int Y);
timer中设置

dylike问这么简单的问题？还是我没理解对？

是这样的,我的思路是用三角函数来实现鼠标的移动,比如鼠标从A点一点点移动到B点.但我数学不好.所以上来求助了.鼠标移动用cursor.posion就可以,主要是实现一点点移动,也就是每个点的坐标计算....

斜边每次步进长度定义为step，移动角度假设为r则

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
	Dim r As Double = 30 * Math.PI / 180
	Dim s As Double = 5
	Dim dx As Double = Math.Cos(r) * s
	Dim dy As Double = Math.Sin(r) * s

	While TextBox1.Left < Me.Width And TextBox1.Top < Me.Height
		TextBox1.Left += dx
		TextBox1.Top += dy
		Application.DoEvents()
		Thread.Sleep(20)
	End While
	MessageBox.Show("move done")
	TextBox1.Location = New Point(12, 12)
End Sub

for 循环

Cursor.Poistion = new Point(x, y);

还是没能解决实质问题.....角度怎么算?比如我要从A点步进移动到B点,要如何实现呢?

谢谢了.我通过百分比的方式实现了.比起三角来更方便些,才几句代码.呵呵
