如何获得vb中鼠标在窗口的坐标

当鼠标在窗口中某一点单击时，显示鼠标坐标数值！

Answer 1

方法一: 直接用 MouseDown事件
举例：（这种方法获取的是点的位置在窗体中，却该对象有MouseDown事件才行，其坐标值为所在容器的相对坐标值）
Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
If Button = 1 Then
Cls
Print "X:"; X, "Y:"; Y
End If
End Sub

方法二：用API函数GetCursorPos来获取位置，用GetAsyncKeyState来获取是否按下左键
这种方法在任何时候都可以获取，哪怕鼠标不在应用程序内也行
在窗体上添加一个计时器，设置Interval属性为10
获取的位置的数字，是屏幕中的位置（不是相对窗体的）
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer
Private Declare Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long

Private Type POINTAPI
X As Long
Y As Long
End Type

Private Sub Timer1_Timer()
Dim P As POINTAPI
X = GetAsyncKeyState(1)
If X = -32767 Then 'x返回的是16位整数，最高位为1，表明按下
Cls
Print "左键按下",
GetCursorPos P
Print " 鼠标x位置：" & P.X & " 鼠标y位置：" & P.Y
End If
X = GetAsyncKeyState(2)
If X = -32767 Then
Cls
Print "右键按下",
GetCursorPos P
Print " 鼠标x位置：" & P.X & " 鼠标y位置：" & P.Y
End If
End Sub

Answer 2

两钟方法:

1..在MouseDown()或者MouseUp()事件里直接用参数X，Y
2..在Click()事件里用API取: GetCursorPos()

此函数声明如下:
Declare Function GetCursorPos Lib "user32" Alias "GetCursorPos" (lpPoint As POINTAPI) As Long

类型:
Type POINTAPI
x As Long
y As Long
End Type

Answer 3

这么简单的问题，楼上不回就别光给个API完事！

直接复制到vb中运行，顺便给你一个显示坐标的代码，需要添加两个 label~呵呵，满意的话，给分哦~

Private Declare Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long

Private Type POINTAPI
X As Long
Y As Long
End Type

Private Sub Form_Click()
Dim firendless As POINTAPI

GetCursorPos firendless
MsgBox " 鼠标x位置：" & firendless.X & " 鼠标y位置：" & firendless.Y

End Sub

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Label1.Caption = (X)
Label2.Caption = (Y)
End Sub
