为 Powershell 脚本中的按钮分配键盘快捷键

Question

我想做的是将按钮分配给快捷键，例如 $TurnOnButton 作为键 "Q"，以及 $TurnOffButton 作为键 "W" 在我的键盘上。

基本上，在我下面的示例中。当脚本是运行ning 并且表格存在时，我可以按下键盘上的按钮 "Q" 到运行计算器，然后按下按钮 "W" 终止它.

这可以用 PowerShell 实现吗？

代码示例：

Add-Type -AssemblyName System.Windows.Forms

function Return-TurnOff
{
    $x = Stop-Process -ProcessName calc
    $x
}

function Return-TurnOn
{
    $x = Start-Process calc
    $x
}

$form = New-Object System.Windows.Forms.Form 
$form.Text = "Title of the form"
$form.Size = New-Object System.Drawing.Size(300,200) 
$form.minimumSize = New-Object System.Drawing.Size(300,200) 
$form.maximumSize = New-Object System.Drawing.Size(300,200) 
$form.StartPosition = "CenterScreen"

$TurnOffButton = New-Object System.Windows.Forms.Button
$TurnOffButton.Location = New-Object System.Drawing.Point(10,125)
$TurnOffButton.Size = New-Object System.Drawing.Size(55,25)
$TurnOffButton.Text = "Turn Off"
$TurnOffButton.Add_Click({Return-TurnOff})
$form.AcceptButton = $TurnOffButton
$form.Controls.Add($TurnOffButton)

$TurnOnButton = New-Object System.Windows.Forms.Button
$TurnOnButton.Location = New-Object System.Drawing.Point(10,65)
$TurnOnButton.Size = New-Object System.Drawing.Size(55,25)
$TurnOnButton.Text = "Turn On"
$TurnOnButton.Add_Click({Return-TurnOn})
$form.AcceptButton = $TurnOnButton
$form.Controls.Add($TurnOnButton)

$CancelButton = New-Object System.Windows.Forms.Button
$CancelButton.Location = New-Object System.Drawing.Point(215,125)
$CancelButton.Size = New-Object System.Drawing.Size(55,25)
$CancelButton.Text = "Cancel"
$CancelButton.DialogResult = [System.Windows.Forms.DialogResult]::Cancel
$form.CancelButton = $CancelButton
$form.Controls.Add($CancelButton)

$label = New-Object System.Windows.Forms.Label
$label.Location = New-Object System.Drawing.Point(10,15) 
$label.Size = New-Object System.Drawing.Size(280,20) 
$label.Text = "Label for textbox:"
$form.Controls.Add($label) 

$textBox = New-Object System.Windows.Forms.TextBox 
$textBox.Location = New-Object System.Drawing.Point(10,35) 
$textBox.Size = New-Object System.Drawing.Size(260,20) 
$form.Controls.Add($textBox) 

$form.Topmost = $True

$form.Add_Shown({$textBox.Select()})
$result = $form.ShowDialog()

如果您不介意按钮上的标签包含与按钮对应的字母并按下 Alt 键，那么这很简单，只需在按钮文本中的字母前加上“&”即可想成为加速器：

$TurnOnButton.Text = "Turn O&n"
$TurnOffButton.Text = "Turn O&ff"

将使 Alt-N 执行开启，Alt-F 执行关闭。

一个更复杂的解决方案是注册键盘按下，但无论是否按下 Alt，它都会让您处理任何击键。 $form|gm -MemberType event key* 将显示名称以 "Key" 开头的事件。然后，您可以 google 了解如何使用 WinForms 处理来自 Powershell 的事件。
