VB 如何获取外部程序文本框内容

我用GetWindowtext只能获文本框名称，不知道怎样获得文本框的内容？

Answer 1

'获取控件的内容
Option Explicit
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Const WM_GETTEXT = &HD
Private Const WM_GETTEXTLENGTH = &HEPublic Function GetTextString(ByVal lyHwnd As Long) As String
Dim GetS As String
Dim SLen As Long
SLen = SendMessage(lyHwnd, WM_GETTEXTLENGTH, 0, 0)
If SLen = 0 Then Exit Function
SLen = SLen + 1
GetS = Space(SLen)
SLen = SendMessage(lyHwnd, WM_GETTEXT, SLen, ByVal GetS)
GetTextString = Left(GetS, SLen)
End Function 控件的句柄你应该能获取到,所以不说了
