如何使用脚本将输出写入 powershell GUI

Question

Powershell 新手在这里。我正在尝试编写一个有用的工具，它有 3 个按钮和一个文本窗口。每个按钮调用一个不同的 powershell (.ps1) 脚本来执行各种操作。如果可以的话，我想将这些脚本的输出写入 GUI 文本窗口，但这似乎比人们想象的要难。如果这太多了，那么至少我想在文本窗口中显示脚本已经运行完成。类似“脚本已运行”。

这是我目前所拥有的。

Add-Type -AssemblyName System.Windows.Forms

function call_Clean 
{
      # Here the path to call your script
      . "C:\Scripts\Script1.ps1"     
}

function call_CreateTestLabConfig 
{
      # Here the path to call your script
      . "C:\Scripts\Script2.ps1"   

}

function call_LocalDeploy 
{
      # Here the path to call your script
      . "C:\Scripts\Script3.ps1"     
}

function CreateFormButton ( $locationheight, $locationwidth, $sizeheight, $sizewidth, $fieldname, $functionname ) {
  $Button = New-Object System.Windows.Forms.Button 
  $Button.Location = New-Object System.Drawing.Size($locationheight, $locationwidth) 
  $Button.Size = New-Object System.Drawing.Size($sizeheight, $sizewidth) 
  $Button.Text = $fieldname 
  $Button.Add_Click( $functionname ) 
  $Form.Controls.Add($Button) 
}

function CreateStartPosition ( $FormSize, $FormLocation ) {
 $Form.Size = New-Object System.Drawing.Size ($varFrmMSizeWidth, $varFrmMSizeHeight)
 $Form.Location = New-Object System.Drawing.Point($varFrmMLocationX, $varFrmMLocationY)
  $Form.Controls.Add($TextWindow) 
}


function CreateTextWindow ( $locationHeight, $LocationWidth, $TextBoxHeight, $TextBoxWidth ) {
  $TextWindow = new-object System.Windows.Forms.ListView
  $TextWindow.Size = New-Object System.Drawing.Size($textBoxHeight,$textBoxWidth)
  $TextWindow.location = new-object system.drawing.point($locationHeight,$LocationWidth)
  $Form.Controls.Add($TextWindow) 
}


$Form = New-Object system.Windows.Forms.Form
$Form.Text = "Test Lab Tool"
#$Form.TopMost = $true
$Form.Size = New-Object System.Drawing.Size (475, 600)
$Form.Location = New-Object System.Drawing.Point(4000, 300)


CreateFormButton 20 100 120 40 'Clean' ${function:call_Clean}
CreateFormButton 170 100 120 40 'Create TestLab Config' ${function:call_CreateTestLabConfig}
CreateFormButton 315 100 120 40 'Local Deploy'
CreateTextWindow 20 160 415 375 'Test'

$Form.ShowDialog()

Answer 1

我建议将这些脚本的输出分配给一个变量并解析该信息（或者如果您知道输出，则仅实现逻辑）以发送到 GUI。例如，如果您使用 Write-Output，它将在分配给变量时被捕获，例如

$Out = & "Script.ps1"

然后你可以做类似的事情

ForEach ($o in $Out)
{
    $str[] += $o
    $TextWindow.Text = $str
    Update()
}

注意：我没有 WindowsForms 经验

Powershell 非常线性。当你调用一个脚本时，它会冻结 GUI 直到它完成。您可以使用基于脚本返回的信息更新 GUI，或者，只需等待脚本完成，然后使用脚本完成的信息更新 GUI。

例如：

function call_Clean 
{
      # Here the path to call your script
      . "C:\Scripts\Script1.ps1"
      $TextWindow.Text = "Call Clean Script Completed"
}

或者：

脚本完成后，您可以在按钮的单击事件中使用相同的 GUI 更新 $TextWindow.Text = "Call Clean Script Completed"。

我已经稍微更新了您的代码，以展示如何访问文本窗口的文本属性。 ==================================================== ==========================

Add-Type -AssemblyName System.Windows.Forms

function call_Clean 
{
      # Here the path to call your script
      . "C:\Scripts\Script1.ps1"
        $Form.Controls | % {
            if($_ -is [System.Windows.Forms.TextBox] -and $_.Name -eq "TestTextBox")
            {
                $_.Text = "test"
            }
        }
}

function call_CreateTestLabConfig 
{
      # Here the path to call your script
      . "C:\Scripts\Script2.ps1"   

}

function call_LocalDeploy 
{
      # Here the path to call your script
      . "C:\Scripts\Script3.ps1"     
}

function CreateFormButton ( $locationheight, $locationwidth, $sizeheight, $sizewidth, $fieldname, $functionname ) {
  $Button = New-Object System.Windows.Forms.Button 
  $Button.Location = New-Object System.Drawing.Size($locationheight, $locationwidth) 
  $Button.Size = New-Object System.Drawing.Size($sizeheight, $sizewidth) 
  $Button.Text = $fieldname 
  $Button.Add_Click( $functionname ) 
  $Form.Controls.Add($Button) 
}

function CreateStartPosition ( $FormSize, $FormLocation ) {
 $Form.Size = New-Object System.Drawing.Size ($varFrmMSizeWidth, $varFrmMSizeHeight)
 $Form.Location = New-Object System.Drawing.Point($varFrmMLocationX, $varFrmMLocationY)
 $Form.Controls.Add($TextWindow) 
}


function CreateTextWindow ( $locationHeight, $LocationWidth, $TextBoxHeight, $TextBoxWidth, $name) {
  $TextWindow = new-object System.Windows.Forms.TextBox
  $TextWindow.Size = New-Object System.Drawing.Size($textBoxHeight,$textBoxWidth)
  $TextWindow.location = new-object system.drawing.point($locationHeight,$LocationWidth)
  $TextWindow.Name = $name
  $TextWindow.Multiline = $true
  $Form.Controls.Add($TextWindow) 
}


$Form = New-Object system.Windows.Forms.Form
$Form.Text = "Test Lab Tool"
#$Form.TopMost = $true
$Form.Size = New-Object System.Drawing.Size (475, 600)
$Form.Location = New-Object System.Drawing.Point(4000, 300)


CreateFormButton 20 100 120 40 'Clean' ${function:call_Clean}
CreateFormButton 170 100 120 40 'Create TestLab Config' ${function:call_CreateTestLabConfig}
CreateFormButton 315 100 120 40 'Local Deploy'
CreateTextWindow 20 160 415 375 'TestTextBox'
