foreach循环的写入进度问题

Question

可能是这个问题的一个非常简单的答案。我无法使写入进度工作。我很确定问题出在我的变量上，但我似乎无法弄清楚究竟是什么。

它现在所做的是在没有任何输出文件存在时第一次运行的炸弹。它会告诉我：

Write-Progress : Cannot validate argument on parameter 'PercentComplete'. The 300 ar gument is greater than the maximum allowed range of 100. Supply an argument that is less than 100 and then try the command again.

的“300说法”它提到是每次不同的随机数。

现在，如果我再次运行脚本，并且现在存在livepcs.txt，它可能会起作用，它可能无法正常工作。即使这样做，进度条也会启动一半。

这是我第一次尝试写入进度的工作，所以它可能是非常简单的东西，但我不太确定要查找的内容。任何建议，你可以提供将不胜感激。

最终代码：

#Import active directory module 
Import-Module active* 

#Query AD for all computers by name filter, AND that have an IP listed in AD, store in variable (use line 10) 

$PCs = Get-ADComputer -Properties * -Filter {name -like "PCNameDomainPrefix*"} | Where-Object {$_.Ipv4Address -ne $null} | select name,ipv4address 

#Dump list of PCs into CSV 
$PCs | Export-Csv c:\script\pcs.csv 

#Begin foreach loop to see which servers are alive 

$i = 0 

$livePCs = ForEach($name.name in $PCs) #specify the name string using .name after the variable 
    { 
    $entry = Test-Connection $name.name -count 1 -quiet #Test-connection pings. The -quiet parameter forces a boolean result (True/False). 
    if ($entry -eq "True") {out-file -InputObject $name.name -Encoding ASCII -Width 50 -Append c:\script\livepcs.txt ; Write-Host "$name.name pings"} 
    else { write-host "server $name could not be contacted"} 
    $i++ 
    Write-Progress -activity "Pinging servers . . ." -status "Pinged: $i of $($PCs.Count)" -percentComplete (($i/$PCs.Count) * 100) 
    } 


#Announce WMI portion of script, clear host to get rid of status bar  
Clear-Host 
Write-Host 
Write-Host 
Write-Host 
Write-Host "Beginning WMI scans. Please wait..."

$livePCs = Get-Content C:\script\livepcs.txt 

#Begin foreach loop to query each live machine using WMI. 

$i = 0  

foreach($livePC in $livePCs) 
{ 
    $entry = Get-WmiObject win32_product -computername $livePC -Filter "Name LIKE '%db2%'" 

    # do the work 
    if ($entry -ne $null) 
    { 
    $livePc,$entry | out-file c:\script\db2pcs.txt -Encoding ASCII -Width 50 -Append 
    Write-Host "$livePC has DB2 installed" 
    } 
    else 
    { 
    write-host "$livePC does not have DB2 installed" 
    } 

    # update counter and write progress 
    $i++ 
    Write-Progress -activity "Scanning WMI . . ." -status "Scanned: $i of $($livePCs.Count)" -percentComplete (($i/$livePCs.Count) * 100) 
}

在最后的循环，你需要每一个WMI查询之后增加你的柜台，然后利用更新值调用Write-Progress。

清理，很好地格式化：

$i = 0  

foreach($livePC in $livePCs) 
{ 
    $entry = Get-WmiObject win32_product -computername $livePC -Filter "Name LIKE '%db2%'" 

    # do the work 
    if ($entry -ne $null) 
    { 
    $livePc,$entry | out-file c:\script\db2pcs.txt -Encoding ASCII -Width 50 -Append 
    Write-Host "$livePC has DB2 installed" 
    } 
    else 
    { 
    write-host "$livePC does not have DB2 installed" 
    } 

    # update counter and write progress 
    $i++ 
    Write-Progress -activity "Scanning WMI . . ." -status "Scanned: $i of $($livePCs.Count)" -percentComplete (($i/$livePCs.Count) * 100) 
}
