: 如何送一字串至某一视窗<p>希望下面的程式能帮到你。<p>You can use the FindWindow and PostMessage API functions to find a window and then close it. This example show how you can close down a Window with a caption of "Calculator".<p>Dim winHwnd As Long<br>Dim RetVal As Long<br>winHwnd = FindWindow(vbNullString, "Calculator")<br>Debug.Print winHwnd<br>If winHwnd <> 0 Then<br>    RetVal = PostMessage(winHwnd, WM_CLOSE, 0&, 0&)<br>    If RetVal = 0 Then<br>        MsgBox "Error posting message."<br>    End If<br>Else<br>    MsgBox "The Calculator is not open."<br>End If<br>                    <br>For this code to work, you must have declared the API functions in a module in your project. You must put the following in the declarations section of the module. <p>Declare Function FindWindow Lib "user32" Alias _<br>"FindWindowA" (ByVal lpClassName As String, _<br>ByVal lpWindowName As String) As Long                    <br>Declare Function PostMessage Lib "user32" Alias _<br>"PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, _<br>ByVal wParam As Long, lParam As Any) As Long                   <br>Public Const WM_CLOSE = &H10                    <br>
