Question

我在另一个网站上找到了这个gui进度条。它解释的方式，应该解决我的问题，当工作运行时不要让gui冻结。

然而，由于我处理批处理文件（安装应用程序），我需要做一个foreach应用程序并逐个安装它们，而不是让gui冻结。

以下是网站link

EDIT: UPDATE the SCRIPT. so far this works but all batch files install at the same time which is causing them to fail. I have more applications but for testing I just added 3.

我假设您要么从某个地方复制它并将其修改为适合您的工作，或者您使用PowerGUI或Sapien之类的东西为您生成脚本，因为在我看来这很难读取代码。 / p>

如果我理解正确，您可以将$JobTrackerList创建为ArrayList个对象。然后，对于要安装的每个应用程序，向PSCustomObject添加ArrayList，其中包含3个属性，一个是在后台运行的Job，一个是在此时运行的脚本已完成，其中一个是更新进度条的脚本。因此每个对象都有一个正在运行的后台作业，这是此时的根本问题。但是等等，我们还没有完成，你有一个计时器正在运行（实际上没有在你给我们的代码中定义）运行，并且它停止的每1000个滴答，检查每个作业，如果它完成它运行＆＃34;完成＆＃34;您为该对象定义的scriptblock，然后从ArrayList中删除该对象。如果仍未完成，则使用＆＃34;更新＆＃34;更新进度条。脚本块。然后它再次启动计时器。

以下我认为需要发生的事情就像你想要的那样......你需要继续制作你的ArrayList，并为你想要的每个应用程序添加对象跑，但不要为他们创造就业机会！创建所有对象后，为第一个应用程序启动作业（并将其作为对象的成员添加，就像之前一样）。然后，当您的脚本检查已完成的作业时，在删除正在查看的对象之前，它应该为下一个对象启动作业。

所以，这需要重新编写代码。我不知道从哪里开始这个，因为你所拥有的代码与我编写代码的方式非常不同，所以我已经给了你我的建议，现在我来了让你从这里运行它。如果您需要帮助编写代码（至少先尝试一下），请告诉我，我会看到我能做些什么。可能不是今天，我已经厌倦了，而不是在我的A游戏中，但是如果你最终需要帮助，我相信明天我能拿出一些东西。

编辑：好的，我认为我的代码可以做你想做的事情，并使用你现有的代码：

$formJobProgress_Load={
    #TODO: Initialize Form Controls here
    $timer1.Interval = 1000
    $timer1.Tag = 0
    $timer1.Start()
    [System.Windows.Forms.Application]::DoEvents()
}

$timerJobTracker_Tick={
    $timerJobTracker.Stop() #Freeze the Timer
    for($index =0; $index -lt $JobTrackerList.Count; $index++){
        $psObject = $JobTrackerList[$index]
        if($psObject -ne $null -AND $psObject.Job -ne $null -AND $psObject.Job.State -ne "Running"){
            #Perform old 'Complete' scriptblock to update progressbar
            $ProgressBarOverlay1.PerformStep()

            #Check if this is the only job, and if not start the next one
            If($JobTrackerList.count -gt 1){
                $NextJob = $JobTrackerList[($index+1)]
                $NextJob.Job = Start-Job -ScriptBlock $NextJob.JobScript
            }
            $JobTrackerList.RemoveAt($index)
            Remove-Job -Job $psObject.Job
            $index-- #Step back so we don't skip a job
        }Else{
            $results = Receive-Job -Job $Job | Select-Object -Last 1
            if ($results -is [int]){
                $progressbaroverlay1.Value = $results
            }
        }

$formMain_FormClosed=[System.Windows.Forms.FormClosedEventHandler]{
    #Stop the timer
    $timerJobTracker.Stop()

    #Remove all the jobs
    while($JobTrackerList.Count -gt 0){
        $job = $JobTrackerList[0].Job
        $JobTrackerList.RemoveAt(0)
        Stop-Job $job
        Remove-Job $job
    }
}


$Appname = @("Adobe_FlashPlayer", "Acrobat_Reader", "Microsoft_RDP_8.1")

$JobTrackerList = New-Object System.Collections.ArrayList

$buttonStartJob_Click= {
    $progressbaroverlay1.Value = 0

    $progressbaroverlay1.Maximum = $Appname.Count

    ForEach($App in $Appname){

        $install = "C:\pstools\Update\cmd\$app\install.cmd"
        $run = "C:\Windows\System32\cmd.exe"

            Set-Location $env:windir
            & $install

        [void]$JobTrackerList.Add((New-Object PSObject -Property @{

}

$timer1_Tick={

    #TODO: Place custom script here

    #if ([timespan]::FromSeconds($timerUpdate.Tag) -ge     [timespan]::Fromminutes(1))
    IF($progressbaroverlay1.Value -eq 100)
    {

        $timerUpdate.stop()
        $formSampleTimer.Close()
    }
    else
    {
        [System.Windows.Forms.Application]::DoEvents()
        $label1.Text = [timespan]::FromSeconds($timer1.Tag++)
    }

}

我希望这适合你。
