vb 2010在面板中找不到鼠标位置的表格 [英] vb 2010 find mouse position in the panel not the form

问题描述

这个问题的标题问了所有这些，我想知道我的鼠标在面板中的位置，而不是例如

我知道了

well the title of the this question asks it all, I wanna know my mouse location in the panel not the form like eg

I get this

If (Windows.Forms.Cursor.Position.X < 30) Then
        Me.Close()
    ElseIf (Windows.Forms.Cursor.Position.X > 30) Then
        Me.WindowState = FormWindowState.Minimized
    End If

但是我想要这个

But I want this

If ( Panel.MousePosition.X  < 30) Then
        Me.Close()
    ElseIf ( Panel.MousePosition.X  > 30) Then
        Me.WindowState = FormWindowState.Minimized
    End If

但是代码总是想更改

but the code always want to change

Panel.MousePosition.X 

回到

back to

Windows.Forms.Cursor.Position.X

并且代码不起作用，只是找到整个表单中的光标位置，而不是我放下的面板

and the code doesn''t work it just find the cursors location in the whole form not that panel I put down

推荐答案

使用方法:

Using:

If ( Panel.MousePosition.X  < 30) Then

您应该得到警告:通过实例访问共享成员；合格表达式将不被评估[ ^ ]

使用事件:

you should get a warning: Access of shared member through an instance; qualifying expression will not be evaluated[^]

Use an event:

Private Sub Panel1_MouseMove(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Panel1.MouseMove
    Me.Text = "X: " & e.X.ToString & " Y: " & e.Y.ToString
End Sub
