文件夾選取器不加載ISE

Question

之外我有一個文件夾選擇對話框啓動腳本，但是據我所知，POSH不能ISE像（STA與MTA）外執行腳本，所以我有一個單獨的腳本點源它。

我在的情況下，用戶按下取消的第一個腳本錯誤處理：

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

現在我需要爲第二個腳本（在一個調用第一個腳本）來檢測同樣取消。

這是我到目前爲止有：

"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") 
} 

這給了我以紅色文字討厭看多線寫入錯誤異常。

 
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 

我不知道爲什麼它生成錯誤消息引用其他腳本，因爲其他腳本運行良好（從ISE當然）。

所需的輸出：

如果用戶取消文件夾選擇器，我只是想要一個乾淨的錯誤消息顯示：

用戶取消了操作。
按任意鍵繼續。

編輯

這裏是文件夾選擇器腳本我有。它在ISE中工作正常，但是當您右鍵單擊並選擇Run with Powershell時，它只會啓動一個空白提示窗口。爲防止最終用戶意外編輯腳本，我希望它能從ISE外部運行。順便說一句，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個腳本函數，點源文件來加載功能，然後將$folder = Select-FolderDialog呼叫你的主腳本，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") 
}
