设置 Powershell 窗口的位置。

Question

我正在尝试生成一个特定大小和位置的新 PowerShell 窗口，目前我有以下代码：

Start-Process powershell -ArgumentList "-noexit", "-command [console]::windowwidth=50; [console]::windowheight=10;","python myscript.py";

但是我找不到一种使用参数或命令来设置窗口位置的方法。

控制台内的缓冲区窗口可以轻松地通过[console]::SetWindowPosition()重新定位，但对于桌面窗口，您需要调用user32.dll!MoveWindow()。 - Mathias R. Jessen

如果您将此函数复制并粘贴到一个文件中，并使用 Import-Module -Path MYPATH 进行导入，您将能够调用它来调整您指定进程的窗口大小。

Function Set-Window {
    <#
        .SYNOPSIS
            Sets the window size (height,width) and coordinates (x,y) of
            a process window.
        .DESCRIPTION
            Sets the window size (height,width) and coordinates (x,y) of
            a process window.

        .PARAMETER ProcessName
            Name of the process to determine the window characteristics

        .PARAMETER X
            Set the position of the window in pixels from the top.

        .PARAMETER Y
            Set the position of the window in pixels from the left.

        .PARAMETER Width
            Set the width of the window.

        .PARAMETER Height
            Set the height of the window.

        .PARAMETER Passthru
            Display the output object of the window.

                $Object            
            }
        }
    }
}

最好的方法是将其作为命令传递到新的PowerShell进程中：

Start-Process powershell -ArgumentList "-noexit","-command (Set-Window -ProcessName $pid -X 1911 -Y '-369' -Width 266 -Height 113)"

希望这有所帮助！
