推荐答案

是的，可以使用PostMessage。我使用了Spy ++程序（它在Visual Studio中，或者您可以下载它 http://mdb-blog.blogspot.com/2010/11/microsoft-spy-or-spyxx-for-download.html ）我运行notepad.exe和Spy ++，并使用了Function FindWindow处理此记事本。然后我使用了Spy-> LogMessages，在Tab Messages中清除了所有内容并保持为复选框，在Keyboard和输出中检查了Raw Message Parameters。

Yes, it's possible using PostMessage. I used program Spy++ (it's inside Visual Studio or you can download it http://mdb-blog.blogspot.com/2010/11/microsoft-spy-or-spyxx-for-download.html) I runed notepad.exe and Spy++, and used Function FindWindow to handle this notepad. Then I used Spy->LogMessages, in Tab Messages I cleared all and stay checkbox Keyboard and in output I checked Raw Message Parameters.

然后在记事本中按alt + 1我注意到了窗口消息中的值。我现在知道了，在哪里使用WM_KEYDOWN，WM_KEYUP，WM_SYSKEYUP等，值分别为lParam，wParam。

Then in notepad i pressed alt+1 and I noted values from Window Messages. I known now, where use WM_KEYDOWN, WM_KEYUP, WM_SYSKEYUP etc. and value lParam, wParam.

我的函数：

    public void PressKeyWithAlt(uint key, uint lParamDown, uint lParamUp)
    {
        PostMessage(hWindow, WM_KEYDOWN, VK_CONTROL, 0x001D0001);
        PostMessage(hWindow, WM_KEYDOWN, VK_MENU, 0x21380001);
        PostMessage(hWindow, WM_KEYDOWN, key, lParamDown);
        Delay(1000);
        PostMessage(hWindow, WM_KEYUP, key, lParamUp);
        PostMessage(hWindow, WM_SYSKEYUP, VK_CONTROL, 0xE01D0001);
        PostMessage(hWindow, WM_KEYUP, VK_MENU, 0xC1380001);
    }

例如alt + 1

PressKeyWithAlt(VK_1, 0x20020001, 0xE0020001);
