Powershell-函数调用在add_click方法中不起作用.请提供建议

Question

我试图在点击事件中调用函数OKButtonEvent，但每当我点击OK按钮时，都不会发生任何事情。我已经创建了复选框，在选中的复选框上，我调用了不同的powershell脚本，但似乎不起作用。我尝试过两种不同的方法，但都无效。一个问题是，如果我确实选择了3个复选框，那么在OK按钮的点击事件中，基于3个所选复选框的所有条件都将执行？

下面是我的脚本：

function Test-AnyButtonChecked
{
if ($checkbox1.Checked -or $checkbox2.Checked -or $checkbox3.Checked -or $checkbox4.Checked) 
{
$OKButton.Enabled = $true
}
else 
{
$OKButton.Enabled = $false
}
}
function OKButtonEvent
{
if ($checkbox1.Checked)
{
echo "hi CB1"
& ((Split-Path $MyInvocation.InvocationName)+"abc.ps1")
}
if ($checkbox2.Checked)
{
write-host "hi CB2"
& ((Split-Path $MyInvocation.InvocationName)+"bcd.ps1")
}
if ($checkbox3.Checked)
{
& ((Split-Path $MyInvocation.InvocationName)+"cde.ps1")
}
if ($checkbox4.Checked)
{
& ((Split-Path $MyInvocation.InvocationName)+"def.ps1")
}
}

function checkbox_test
{
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")

所以我为工作中的扫描仪制作了这个应用程序。它读取条形码并列出它们。然后当你想把标签打印出来的时候。。。。应用程序通过自动执行来帮助我们，。。。

试试看…在里面放一些数字、单词或字母。。。

#$aNewSheet = [autoPrintForm]::new() 
$aNewSheet = [autoPrintForm]::new(185)

或者看看这个。。。

$this.autoButton is of a type
[object]$autoButton in a powershell class...think
$this.autoButtonX as
[int]$autoButtonX or as
$this.SautoButtonX
is the X size while
$this.PautoButtonX
is the X point on the form. 

在你的班级

class someFormWithBoxes
{
[object]$OformP
[object]$autoButton
[int]$SautoButtonX
[int]$SautoButtonY
[int]$PautoButtonX
[int]$PautoButtonY
#.....keep going
#you can list as many things as you want...any object in c# 
#usually have some functionality in powershell code as types

[void]startForm()
{...#create a form}
[void]addAutoButton()
{



$this.autoButton = New-Object System.Windows.Forms.Button
$this.autoButton.Location = New-Object System.Drawing.Point($this.autoButtonX,$this.autoButtonY)
$this.autoButton.Size = New-Object System.Drawing.Size($this.RbuttonSizeX,$this.RbuttonSizeY)
$this.autoButton.Text = 'AUTO'
$this.autoButton.backcolor = "indianred"
$this.formP.Controls.Add($this.autoButton)

$thisAUTOBUTTON = $this 
$this.autoButton.add_click({
$thisAUTOBUTTON.autoClick()
}.GetNewClosure())
}
autoclick()
{#your code here referencing the objects defined in the class}
}

并使用类似的工作流来控制整个表单及其属性变量。由于您使用的是复选框，因此您应该查找这些复选框并遵循类似的工作流程。检查此页面左栏上的构造函数、属性、方法和事件，以便更深入地了解操作系统使用的项和对象。
