如何在代码执行期间禁用Powershell GUI按钮?

我无法在功能操作期间禁用按钮。如果我在单击按钮时将其禁用,则从外观上看它是禁用的,但它仍然可以工作(或更确切地说,它使单击排队)。

这是我正在测试的有效演示代码:

Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.Application]::EnableVisualStyles()

$Form                            = New-Object system.Windows.Forms.Form
$Form.ClientSize                 = '400,400'
$Form.text                       = "Form"
$Form.TopMost                    = $false
$Button1                         = New-Object system.Windows.Forms.Button
$Button1.text                    = "button"
$Button1.width                   = 100
$Button1.height                  = 25
$Button1.enabled                 = $true
$Button1.location                = New-Object System.Drawing.Point(214,59)
$Button1.Font                    = 'Microsoft Sans Serif,10'

$Form.controls.AddRange(@($Button1))

Function Test {
    Write-Host "Clicked"
    $Button1.Enabled = $false
    Start-Sleep -Seconds 2
    $Button1.Enabled = $true
}

$Button1.add_Click(
    {
        Test
    }
)
[void]$Form.ShowDialog()

I have tried putting in [System.Windows.Forms.Application]::DoEvents() and button1.Update() in the function.

我尝试在初始功能中禁用按钮,然后在与按钮单击不同的单独功能中调用需要花费较长时间的部件,但该部件也不起作用。即:

Function DisableBtn1 {
    $Button3.Enabled = $false
}

Function DoStuff {
    Write-Host "Bt1 Clicked"
    Start-Sleep -Seconds 2
    $Button3.Enabled = $True

}

$Button1.add_Click(
    {
        DisableBtn3
        DoStuff
    }
)

在脚本运行时正确禁用GUI元素方面,我是否缺少明显的东西?

做这个简单的测试将显示我的意思:

Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.Application]::EnableVisualStyles()

$Form                            = New-Object system.Windows.Forms.Form
$Form.ClientSize                 = '400,400'
$Form.text                       = "Form"
$Form.TopMost                    = $false
$Button1                         = New-Object system.Windows.Forms.Button
$Button1.text                    = "button"
$Button1.width                   = 100
$Button1.height                  = 25
$Button1.enabled                 = $true
$Button1.location                = New-Object System.Drawing.Point(214,59)
$Button1.Font                    = 'Microsoft Sans Serif,10'

$Form.controls.AddRange(@($Button1))

Function Test 
{
    Write-Host 'Clicked'
    $Button1.Enabled = $false
    $Button1.IsAccessible = $false
    Start-Sleep -Seconds 2
    $Button1.Enabled = $true
}

$Button1.add_Click(
    {
        Test
    }
)
[void]$Form.ShowDialog()

只是不要使用启用线

Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.Application]::EnableVisualStyles()

$Form                            = New-Object system.Windows.Forms.Form
$Form.ClientSize                 = '400,400'
$Form.text                       = "Form"
$Form.TopMost                    = $false
$Button1                         = New-Object system.Windows.Forms.Button
$Button1.text                    = "button"
$Button1.width                   = 100
$Button1.height                  = 25
$Button1.enabled                 = $true
$Button1.location                = New-Object System.Drawing.Point(214,59)
$Button1.Font                    = 'Microsoft Sans Serif,10'

$Form.controls.AddRange(@($Button1))

Function Test 
{
    Write-Host 'Clicked'
    $Button1.Enabled = $false
    Start-Sleep -Seconds 2
}

$Button1.add_Click(
    {
        Test
    }
)
[void]$Form.ShowDialog()
