文件夹选取器不加载ISE

Question

之外我有一个文件夹选择对话框启动脚本，但是据我所知，POSH不能ISE像（STA与MTA）外执行脚本，所以我有一个单独的脚本点源它。

我在的情况下，用户按下取消的第一个脚本错误处理：

if ($Show -eq "OK") { 
    return $objForm.SelectedPath 
} else { 
    Write-Error "Operation cancelled by user." 
    exit 
} 

现在我需要为第二个脚本（在一个调用第一个脚本）来检测同样取消。

这是我到目前为止有：

"Choose a folder containing the items to be moved..." 
"" 
try { 
    powershell -STA -File "C:\Test\Script.ps1" 
    "" 
    "Operation completed. An event log has been created:" 
    (Resolve-Path .\).Path +"\log.txt" 
    "" 
    "Press any key to continue..." 
    "" 
    $x = $Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown") 
} catch { 
    if ($LastExitCode -ne 0) { exit $LastExitCode } 
    Write-Host "User cancelled the operation." 
    "" 
    "Press any key to continue..." 
    "" 
    $x = $Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown") 
} 

这给了我以红色文字讨厌看多线写入错误异常。

 
At C:\Test\Script.ps1:27 char:30 
+ $folder = Select-FolderDialog <<<< #contains user's selected folder 
    + CategoryInfo   : NotSpecified: (:) [Write-Error], WriteErrorException 
    + FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,Select-FolderDialog 

我不知道为什么它生成错误消息引用其他脚本，因为其他脚本运行良好（从ISE当然）。

所需的输出：

如果用户取消文件夹选择器，我只是想要一个干净的错误消息显示：

用户取消了操作。
按任意键继续。

编辑

这里是文件夹选择器脚本我有。它在ISE中工作正常，但是当您右键单击并选择Run with Powershell时，它只会启动一个空白提示窗口。为防止最终用户意外编辑脚本，我希望它能从ISE外部运行。顺便说一句，我使用POSH 2.

# Function for folder picker dialog 
Function Select-FolderDialog 
{ 
[System.Reflection.Assembly]::LoadWithPartialName("System.windows.forms") | Out-Null  

$objForm = New-Object System.Windows.Forms.FolderBrowserDialog 
# Default location is script's location 
$objForm.SelectedPath = (Resolve-Path .\).Path 
$objForm.Description = "Select Folder" 
$Show = $objForm.ShowDialog() 
If ($Show -eq "OK") 
{Return $objForm.SelectedPath} 
    Else 
    { 
    Write-Error "Operation cancelled by user." 
    Exit 
    } 
} 
$folder = Select-FolderDialog #contains user's selected folder 

Answer 1

保持只是你在你的第二个脚本函数，点源文件来加载功能，然后将$folder = Select-FolderDialog呼叫你的主脚本，一拉：

"Choose a folder containing the items to be moved..." 
"" 
try { 
    . "C:\Test\Script.ps1" # this dot sources the function from the second file (no need to call a separate Powershell process to do this, as data from that process won't be returned to the primary process calling it) 

    $folder = Select-FolderDialog # this runs the function in your original script, storing the result in the $folder variable 

    "" 
    "Operation completed. An event log has been created:" 
    (Resolve-Path .\).Path +"\log.txt" 
    "" 
    "Press any key to continue..." 
    "" 
    $x = $Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown") 
} catch { 
    if ($LastExitCode -ne 0) { exit $LastExitCode } 
    Write-Host "User cancelled the operation." 
    "" 
    "Press any key to continue..." 
    "" 
    $x = $Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown") 
}
