最佳答案
感谢@TinMan 和@Remy 为我指明了正确的方向。感谢您没有给我答案并允许我研究..
以下代码完美运行,将完全替换我以前的代码。
请注意,下面的代码更加简洁明了。
Option Explicit
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" _
(ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Const WM_COMMAND = &H111
Private Const IDNO = 7
Public Declare PtrSafe Function SendMessage Lib "user32.dll" Alias "SendMessageW" ( _
ByVal hwnd As LongPtr, _
ByVal wMsg As Long, _
ByVal wParam As LongPtr, _
ByVal lParam As LongPtr) As LongPtr
Sub PressNo_SAPTimeout_Wnd()
Dim hwnd As Long
hwnd = FindWindow(vbNullString, "SAP GUI for Windows 740")
If (hwnd <> 0) Then
SendMessage hwnd, WM_COMMAND, IDNO, ByVal 0&
Else
MsgBox "Error finding message box!", vbOKOnly
End If
End Sub
