powershell-3.0

问题 Background Info : I have an application that makes several SQL connections to multiple databases which currently takes a very very long time to execute. Powershell (.NET) will wait for each proceeding " SQL-GET " function to finish before it can fire off the next. I am under the impression I can speed this app up dramatically by firing each " SQL-GET " function in their own background job simultaneously!I will then retrieve the data from each job as they finish. Ideally as a DataSet system

问题 So I'm still fairly new to Powershell and I'm trying to write a script that allows the user to select a file or folder and then get back the security permissions for said folder/file. The problem is, I can't seem to get the file path to record as a variable to be used later. Here's what I have so far: Function Get-Folder($initialDirectory) { [System.Reflection.Assembly]::LoadWithPartialName("System.windows.forms") $foldername = New-Object System.Windows.Forms.FolderBrowserDialog $foldername

Required? false Position? 1 Default value Current directory Accept pipeline input? true (ByValue, ByPropertyName) Accept wildcard characters? true I created a function with a Path parameter that

问题 How do you implement the parameter tab completion for PowerShell functions or cmdlets like Get-Service and Get-Process in PowerShell 3.0? I realise ValidateSet works for a known list, but I want to generate the list on demand. Adam Driscoll hints that it is possible for cmdlets but unfortunately hasn't elaborated. Trevor Sullivan shows a technique for functions, but as I understand it, his code only generates the list at the time the function is defined. 回答1: Check the TabExpansionPlusPlus

问题 I would like to use PowerShell 2 as the default PowerShell version on Windows 8 without specifying the -Version switch. I started using Windows 8 RTM which comes with PowerShell 3, and I have scripts that are not compatible with PowerShell 3. 回答1: Powershell uses a publisher policy (see here also) to automatically redirect hosts built against Powershell 2 onto the Powershell 3 runtime if it's available. Most of the time this is exactly what you want, however you can explicitly disable the
