VB 引用API就是超麻烦啊“hwnd”不是“System.Windows.Forms.TextBox”的成员。该如何处理

VB 引用API就是超麻烦啊，“hwnd”不是“System.Windows.Forms.TextBox”的成员。
Private Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long, ByVal lpString As String, ByVal cch As Long) As Long
  Private Sub Command1_Click()
  Dim sBuffer As String
   
  sBuffer = Space(255)
  GetWindowText Text1.hwnd, sBuffer, 255
   
  Text2.Text = sBuffer
  End Sub







错误1“hwnd”不是“System.Windows.Forms.TextBox”的成员。X:\vb\getwindowtext\WindowsApplication1\WindowsApplication1\Form1.vb1823WindowsApplication1

  一个在VS2010下就这么麻烦，要怎么改。出手吧。

句柄應該是
.handle
[解决办法]
Private Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As intptr, ByVal lpString As String, ByVal cch As int32) As int32
Private Sub Command1_Click()
Dim sBuffer As String

sBuffer = Space(255)
GetWindowText Text1.handle, sBuffer, 255

Text2.Text = sBuffer
End Sub

楼住api声明错误。vb6的long数据类型在vb。net为int32

其他的就不说了。6楼正解
