使用Powershell GUI +刷新

Question

我在这里挣扎。

把这个示例代码：

[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing") 
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") 

$objForm = New-Object System.Windows.Forms.Form 
$objForm.Text = "Data Entry Form" 
$objForm.Size = New-Object System.Drawing.Size(500,400) 
$objForm.StartPosition = "CenterScreen" 

$objForm.KeyPreview = $True 
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Enter") 
    {$output1=$objTextBox.Text}}) 
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Escape") 
    {$objForm.Close()}}) 

$OKButton = New-Object System.Windows.Forms.Button 
$OKButton.Location = New-Object System.Drawing.Size(100,90) 
$OKButton.Size = New-Object System.Drawing.Size(75,23) 
$OKButton.Text = "Merge" 
$OKButton.Add_Click({$output=$objTextBox.Text}) 
$objForm.Controls.Add($OKButton) 

$CancelButton = New-Object System.Windows.Forms.Button 
$CancelButton.Location = New-Object System.Drawing.Size(300,90) 
$CancelButton.Size = New-Object System.Drawing.Size(75,23) 
$CancelButton.Text = "Cancel" 
$CancelButton.Add_Click({$objForm.Close()}) 
$objForm.Controls.Add($CancelButton) 

$objLabel = New-Object System.Windows.Forms.Label 
$objLabel.Location = New-Object System.Drawing.Size(160,20) 
$objLabel.Size = New-Object System.Drawing.Size(280,20) 
$objLabel.Text = "Please enter the target machine: " 
$objForm.Controls.Add($objLabel) 

$output = new-object System.Windows.forms.label 
$output.location = new-object System.drawing.size(30, 140) 
$output.size = New-Object System.Drawing.Size(300,300) 
$objform.controls.add($output) 

$objTextBox = New-Object System.Windows.Forms.TextBox 
$objTextBox.Location = New-Object System.Drawing.Size(115,40) 
$objTextBox.Size = New-Object System.Drawing.Size(260,20) 
$objForm.Controls.Add($objTextBox) 

$objForm.Topmost = $True 

$objForm.Add_Shown({$objForm.Activate()}) 
[void] $objForm.ShowDialog() 
$output 

我不能为我的生命弄清楚为什么当我输入文本框，然后单击OKButton（合并）没有happns。它应该输出到$输出，或者至少，这就是我想要发生的事情。

我只是试图让代码接受文本框的输入并将其输出到名为$ output的标签形式。

我已经得到它的工作原理，当我把输入文本框并按'合并'，它会输出到Powershell_ISE控制台，但只有在窗口关闭并运行一秒后时间（当我按'合并'时不会刷新$输出标签，只有在关闭程序时才输出）

请帮忙！

谢谢

修改

$OKButton.Add_Click({$output=$objTextBox.Text}) 

到

$OKButton.Add_Click({$output.text=$objTextBox.Text})
