高手帮忙看看这段代码为什么不执行？谢谢！

Private Sub Command1_Click()
Dim Handle As Long
Handle = FindWindow(vbNullString, "a - 记事本")

If Not Handle = 0 Then
SendMessage Handle, WM_CHAR, vbKeyReturn, 0
End If

End Sub

（API已声明）
能返回句柄，但是Sendmessage没用~

解决拉~~

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 Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long
Private Const WM_CHAR = &H102


Private Sub Command1_Click()
Dim fHwnd, iHwnd As Long

fHwnd = FindWindow(vbNullString, "a - 记事本")

If fHwnd <> 0 Then
iHwnd = FindWindowEx(fHwnd, ByVal 0&, "Edit", vbNullString)
End If

If iHwnd <> 0 Then SendMessage iHwnd, WM_CHAR, vbKeyA, 0
End Sub

你的handle找到了吗？
你可以print handle如果为零则未找到
