Question

我一直在努力寻找答案，但是我的研究并未提出很多对我的情况有所帮助的东西。我需要在创建的批处理文件中模拟Windows密钥。这是为了帮助我最大化窗口，以及在不使用鼠标的情况下轻松地在监视器之间移动窗口。这批工作站将自动运行，无法访问鼠标或物理键盘。

这是我正在使用的代码。

    @if (@CodeSection == @Batch) @then

    @echo off

    rem Use %SendKeys% to send keys to the keyboard buffer
    set SendKeys=CScript //nologo //E:JScript "%~F0"

    rem Start the other program in the same Window
    Start "Progam"

    rem the script only works if the application in question is the active window. Set a timer

    timeout /t 10

    rem use the tab key to move the cursor to the login and password inputs.

    %SendKeys% "This would be the username{TAB}"
    %SendKeys% "this would be the password{ENTER}"

    rem I then have a timer to let the login happen

    timeout /t 10

    rem this where I am now trying to maximize and move the active window around.


    goto :EOF


    @end
    // JScript section

    var WshShell = WScript.CreateObject("WScript.Shell");
    WshShell.SendKeys(WScript.Arguments(0));

好问题！是的，我前段时间不得不为此战斗。我想在启动时自动启动从Microsoft Store安装的应用程序，由于这个原因，最简单的方法是将其固定到任务栏，然后模拟命中 ⊞ + 1 启动它。我认为现在是这种情况，但是没有办法SendKeys() Windows元密钥。但是感谢LandOfTheLostPass on reddit，我发现了SendKeys()的另一种选择：发送键盘扫描代码。

我修改了reddit中的代码，使我可以模拟按下多个键，然后释放它们。如果我没记错的话，reddit上的代码只会模拟按下，然后一次释放一个键。我只修改了多键组合的扫描代码功能。现在重新检查代码，看来我可能已经破坏了SendChars()函数。但是我还是没用过。

请参见Virtual-Key Codes on Microsoft Docs查找其他按键的扫描代码。

顺便说一句，Windows API提供了other ways，可以在不模拟键盘快捷键的情况下最大化和移动窗口。（请不要太严厉地判断。在学习如何编写批处理+ PowerShell混合脚本或在PowerShell中包含.NET代码之前，我曾写过该hack。）
