powershell-2.0

We were trying to parallelize our build with dependency graph and topological sorting. All our build logic is written in Msbuild and we are using powershell to call it. Has any one implemented dependency graph and topological sorting using powershell? I know that in unix there is a utility called tsort available. Is there any thing similar available in powershell? This article gives good idea but it is done in C# " http://msdn.microsoft.com/en-us/magazine/dd569760.aspx" I did a quick translation of Wikipedia's Topological Sort Algorithm : function Get-TopologicalSort { param( [Parameter

I am trying to assign an array as a value to a dictionary entry as follows but its throwing exception. $sd = New-Object 'System.Collections.Generic.SortedDictionary[int, string[]]' $sd[0] = "Data1a", "asda"; Any idea? Use cast to [string[]] : $sd = New-Object 'System.Collections.Generic.SortedDictionary[int, string[]]' $sd[0] = [string[]]("Data1a", "asda") Another options is to change the dictionary value type to object[] : $sd = New-Object 'System.Collections.Generic.SortedDictionary[int, object[]]' $sd[0] = "Data1a", "asda" 来源： https://stackoverflow.com/questions/4658759/assigning-an-array

I am writing the following code to close all explorer windows with PowerShell: (New-Object -comObject Shell.Application).Windows() | ? { $_.FullName -ne $null} | ? { $_.FullName.toLower().Endswith('\explorer.exe') } | % { $_.Quit() } But it does not close out all the open windows. Instead, it closes only RoundDown(N/2)+1 windows, and leaves RoundUp(N/2)-1 windows open. Can anyone help with this? I think there's something in the pipeline that goes wrong. This code works: $a = (New-Object -comObject Shell.Application).Windows() | ? { $_.FullName -ne $null} | ? { $_.FullName.toLower().Endswith('

I want to set a time limit on a PowerShell (v2) script so it forcibly exits after that time limit has expired. I see in PHP they have commands like set_time_limit and max_execution_time where you can limit how long the script and even a function can execute for. With my script, a do/while loop that is looking at the time isn't appropriate as I am calling an external code library that can just hang for a long time. I want to limit a block of code and only allow it to run for x seconds, after which I will terminate that code block and return a response to the user that the script timed out. I

Documentation states: Adds a user-defined custom member to an instance of a Windows PowerShell object. What "Windows PowerShell object" stands for? This works fine: $obj = new-object system.object $obj | add-member -membertype noteproperty -name Name -value "OK" $obj.name But this does not: $obj = @{} Actually, I am trying to add property to $error[0]. PowerShell has what's called a PSObject that is a wrapper around any .NET object (or it can be a totally custom object) and when you call Add-Member, PowerShell is implicitly wrapping the real .NET object with a PSObject. The way Add-Member
