下面的代码显示了如何按文件名关闭应用程序。它在不保存文档的情况下关闭它，如果我在记事本中指向一个文件名，它不会直接关闭，而是询问是否保存。我想通过直接保存文档来关闭应用程序。

有什么想法可以更正代码吗？

Const WM_Close As UInteger = &H10
    Const WM_KEYDOWN = &H100
    Const WM_COMMAND = &H112

Private Sub searchnclosedoc(ByVal noextfilename As String, ByVal ms_appname As String)
    For Each wproc As Process In Process.GetProcessesByName(ms_appname)
        If wproc.MainWindowTitle.Contains(noextfilename) Then
            If PostMessage(wproc.MainWindowHandle, WM_Close, WM_KEYDOWN, Keys.Enter) Then
                'MessageBox.Show("not closed, dialog asked")
                'PostMessage(wproc.MainWindowHandle, WM_KEYDOWN, WM_COMMAND, Keys.Enter)
                MyThreadedControl(lbltest, "Text", noextfilename & " was SAVED and CLOSED to Prevent Conflict")
            Else
                MyThreadedControl(lbltest, "Text", noextfilename & " was CLOSED to Prevent Conflict")
            End If
        End If
    Next
    End Sub

这会关闭 msword 而不询问是否保存。这不会在关闭后保存文档。但我希望在关闭之前保存文档。在记事本中会出现一个对话框，询问是否保存。我想关闭应用程序并直接保存编辑的文档而不显示对话框。

    PostMessage(wproc.MainWindowHandle, WM_Close, WM_KEYDOWN, Keys.Enter)

这就是我使用该程序的方式，

           searchnclosedoc(dfilenamewithoutextension, "MSWORD")
           searchnclosedoc(dfilenamewithoutextension, "notepad")

这个我也试过

Private Sub searchnclosedoc(ByVal noextfilename As String, ByVal ms_appname As String)
    For Each wproc As Process In Process.GetProcessesByName(ms_appname)
        If wproc.MainWindowTitle.Contains(noextfilename) Then
            If PostMessage(wproc.MainWindowHandle, WM_Close, 0, 0) Then
                'MessageBox.Show("not closed, dialog asked")

                Dim h, h2, h3, h4 As IntPtr
                If ms_appname = "notepad" Then
                    h = FindWindowA(h, "Notepad")
                ElseIf ms_appname = "Foxit Reader" Then
                    h = FindWindowA(h, "Foxit Reader")
                Else
                    h = FindWindowA(h, ms_appname)
                End If

                If h = 0 Then Exit Sub

                If ms_appname = "notepad" Then
                    h2 = FindWindowEx(h, IntPtr.Zero, "Button", "&Yes")
                ElseIf ms_appname = "Foxit Reader" Then
                    h2 = FindWindowEx(h, IntPtr.Zero, "Button", "&No")
                Else
                    h3 = FindWindowEx(h, IntPtr.Zero, "Button", "&Save")
                End If

                If h2 <> 0 Then h4 = h2 Else h4 = h3
                If h4 <> 0 Then
                    PostMessage(h4, &HF5, 0, 0)
                End If

                MyThreadedControl(lbltest, "Text", noextfilename & " was SAVED and CLOSED to Prevent Conflict")
            Else
                MyThreadedControl(lbltest, "Text", noextfilename & " was CLOSED to Prevent Conflict")
            End If
        End If
    Next
End Sub

记事本不好，它保存，有时它还用对话框询问，福昕阅读器是好的，不保存为NO，msWORD不保存并直接关闭我想关闭，保存，关闭。

使用此代码解决：（我更改代码）在下面。

Private Sub searchnclosedoc(ByVal noextfilename As String, ByVal ms_appname As String)
    For Each wproc As Process In Process.GetProcessesByName(ms_appname)
        If wproc.MainWindowTitle.Contains(noextfilename) Then
            SetForegroundWindow(wproc.MainWindowHandle)
            SendKeys.SendWait("^(s)")
            Thread.Sleep(100)
            SendKeys.SendWait("%{F4}")
            Thread.Sleep(100)
            SendKeys.SendWait("{ENTER}")
            MyThreadedControl(lbltest, "Text", noextfilename & " was SAVED and CLOSED to Prevent Conflict")
        End If
    Next
End Sub

暂时使用此代码：并且工作正常。

Private wordApp as New Word.Application
Private Sub searchnclosedoc(ByVal noextfilename As String, ByVal ms_appname As String)
    For Each wproc As Process In Process.GetProcessesByName(ms_appname)

        If ms_appname.Contains("WINWORD") Then
            If wproc.MainWindowTitle.Contains(noextfilename) Then
                wordapp = DirectCast(GetObject(, "Word.Application"), Word.Application)
                AddHandler wordapp.DocumentBeforeClose, AddressOf WordClose
                PostMessage(wproc.MainWindowHandle, WM_Close, 0, 0)
                MyThreadedControl(lbltest, "Text", noextfilename & " was SAVED and CLOSED to Prevent Conflict")
            End If
        End If

    Next
End Sub

谢谢

您是否尝试在发送 WM_Close 之前发送 Ctrl-S？
