VB.NET想用GetWindowRECT获取某窗口的坐标，但测试结果是L,T,R,B显示都是0,0,0,0

很简单，原因有二。第一，VB里long是32位，但是VB.NET里是64位，Dim ksWND As Integer才对。第二，VB在API里默认传址，而VB.NET默认传值，所以API里要添加Private Declare Function GetWindowRect Lib "user32" (ByVal hwnd As Long,添加"ByRef" lpRect As RECT) As Integer

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long

Private Declare Function GetWindowRect Lib "user32" (ByVal hwnd As Long,byref lpRect As RECT) As Integer

Private Structure RECT

Dim Left As Integer

Dim Top As Integer

Dim Right As Integer

Dim Bottom As Integer

End Structure

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

Dim ksWND As integer

Dim ksTitle As String

Dim winS As RECT

If TextBox1.Text "" Then

ksTitle = TextBox1.Text

ksWND = FindWindow(vbNullString, ksTitle)

GetWindowRect(ksWND, winS)

MsgBox("左上角坐标(" winS.Left "," winS.Top ")" vbCrLf "右下角坐标(" winS.Right "," winS.Bottom ")" vbCrLf "窗口高" winS.Bottom - winS.Top "窗口宽" winS.Right - winS.Left)

Else

MsgBox("请填写窗口名称")

End If

End Sub

在VB点虐 中怎么获取 鼠标在屏幕中的坐标

Private Declare Function GetCursorPos Lib "user32" (ByRef lpPoint As POINTAPI) As Long '全屏坐标声明

Private Declare Function ScreenToClient Lib "user32.dll" (ByVal hwnd As Int32, ByRef lpPoint As POINTAPI) As Int32 '窗口坐标声明

Private Structure POINTAPI '声明坐标变量

Public x As Int32 '声明坐标变量为32位

Public y As Int32 '声明坐标变量为32位

End Structure

'以上是声明部分

'以下是窗口部分

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick '用时钟控件来取坐标,窗口上放个Timer组件,Enabled为允许,周期为10到100毫秒均可

Dim P As POINTAPI '声明坐标变量

Dim xx, yy '声明转换要用到的变量

GetCursorPos(P) '获取鼠标在屏幕中的位置

ScreenToClient(Me.Handle.ToInt32, P) '转换为本窗体的坐标

xx = P.x.ToString '把X转换成能显示到文本框的字符串格式

yy = P.y.ToString '把Y转换成能显示到文本框的字符串格式

TextBox1.Text = xx + "和" + yy '文本框的内容为X坐标和Y坐标

End Sub

vb点虐 怎么判断文本框 失去焦点 ？ 怎么在代码中定义控件的坐标

（1）失去焦点，拖一个文本框到页面上，选择该文本框，查看一下该文本框的事件，里面应该有文本框的焦点事件，自己查查看。

（2）如果是winform的话在控件的属性里应该有坐标的属性项可以填写。web的话需要html的布局来确定该文本框的位置。
