vb.net 从进程获取窗体

问题：

请问 vb.net 2008 
如何将 一个 指定  窗口  定义为 一个窗口..
比如说,一个记事本窗口,定庑为 一个窗口form
然后,我就可以用 form.top  来得到这个记事本窗口的纵坐标了.

其实说简单点.我只是想获取指定窗口的位置

答案：

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String,ByVal lpWindowName As String) As Integer
Private Declare Function GetWindowRect Lib "user32" (ByVal hwnd As Integer,lpRect As RECT) As Integer
Structure RECT
Dim Left As Integer
Dim Top As Integer
Dim Right As Integer
Dim Bottom As Integer
End Structure
Private Sub Form1_Load(ByVal sender As System.Object,ByVal e As System.EventArgs) Handles MyBase.Load
Dim h As Integer,r As RECT
h = FindWindow(vbNullString,"记事本") 
GetWindowRect h,r
MsgBox "左上角坐标(" & r.Left & "," & r.Top & ")" & vbCrLf & "右下角坐标(" & r.Right & "," & r.Bottom & ")" & vbCrLf & "窗口高" & r.Bottom - r.Top & "窗口宽" & r.Right - r.Left
End
End Sub
