  1. Powershell not interpreting spaces correctly

    I am running a powershell script in the Post-Build event in Visual Studio (VS). Here is a simplified version of the command command

    powershell -ExecutionPolicy remotesigned -File "%SampleDir%\update.ps1" "$(ProjectDir)" "$(TargetName)" "$(TargetExt)" "$(Configuration)"

    I want you to understand that I have no control of these macro's $(ProjectDir) ... VS will fill these in.

    To simplify things I've eliminated VS. Here is a script that simply echo's the input given to it. This will show the problem copy the below script to a file called echo-args.ps1
    #===================================
    "The number of parameters passed in is $($Args.Count)"
    $i = 0
    foreach ($arg in $Args)…

    • Timing Invoke-WebRequest Is Slower in Console than ISE

      We are running a home-grown internet speedtest using a PowerShell script. When running the script in ISE on fast network connections (100mbps+), the Invoke-WebRequest commands run fast enough to reflect 100mbps. However, when the script is run through console, the Invoke-WebRequest is restricted and reports speeds of only 25mbps. How can the console be configured to run with the same resources as ISE?

      FYI, this is not an issue for slower networks. Only fast networks seem to expose the console bottleneck.

        • write-host -NoNewline parameter is ignored with powershell 5.1

          Starting with WMF 5.0 and WMF 5.1 the -NoNewLine option for Write-Host is essentially ignored.

          Simple example:
          PS C:\> Write-Host "no newline test " -NoNewline

          Current Behaviour:
          no newline test
          PS C:\>

          Expected Behavior
          no newline test PS C:\>

          PS version Table is as follows.

          Name Value
          ---- -----
          PSVersion 5.1.14409.1012

          • switch break

            Switch should allow for implied breaks.

            I think it would be useful, if it doesn’t exist to have an additional option, e.g.

            switch -ImplyBreak ($variable) {
            ‘red’ { ‘r’ }
            ‘green’ { ‘g’ }
            }

            Where -ImplyBreak would make the code above equivalent to:

            switch ($variable) {
            ‘red’ { ‘r’; break }
            ‘green’ { ‘g’; break }
            }

            • Please modify clause ($var -in 1..3)

              Please modify clause ($var -in 1..3) not to use a list in memory.

              The code becomes unusable when using long ranges like 1..20000000

              Thanks

              • Powershell write-progress memory leak in remote sessions

                Hello, I have noticed some strange behavior with Powershell when run in a remote session, it seems as if there is a memory leak with write-progress when run in a remote session.

                Take the following code for example:

                $MaxVal = 10000000

                for ($x=1;$x -le $MaxVal;$x++)
                {
                Write-Progress -Activity "Writing a progress event" -PercentComplete ($x / $MaxVal * 100) -Status "$($x / $MaxVal * 100)% complete"
                }

                If I run this locally, powershell.exe runs normally and does not take up much memory.

                However, if I run it on the same computer from a remote session (as in, I do an enter-psesssion…

                  • Allow custom message when using the confirm parameter

                    Although PowerShell creates a message describing the action about to take place when using the confirm parameter, it would be helpful to have the ability to create a custom message in order to make the dialog more user friendly or provide more detail about what action is about to take place.

                    • Fatal error when using a class when the script is in the folder containing a single quote

                      Create a script called "C:\Temp'Test\Test.ps1" and add the following lines:

                      Write-Host "Test"
                      Class MyClass {}

                      Execute this script and you get this error:

                      The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047) At line:1 char:1 + & 'C:\Temp''Test\Test..ps1' + ~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : OperationStopped: (:) [], FileLoadException + FullyQualifiedErrorId : System.IO.FileLoadException

                      Rename the folder as simply C:\Test and it runs without an error.

                      • Terminating error in if statement script block generates duplicate errorvariable entries

                        Consider the following 2 functions (contrived to illustrate the issue).

                        function 1error { [CmdletBinding()] Param(); throw "This produces 1" }
                        function 2error { [CmdletBinding()] Param(); if($true) {throw "This produces 2"} }

                        If you call the function 1error with an error variable, the error variable will act as expected.

                        1error -ErrorVariable +1var
                        $1var.count #results in 1

                        If you call function 2error with an error variable, the error variable will have 2 identical errors.

                        2error -ErrorVariable +2var
                        $2var.count # results in 2

                        PSVersion is 5.1.14393.2189

                        • Using DontShow for a parameter should not hide all CommonParameters from auto-complete

                          Using "DontShow = $true" for a parameter has the unexpected side effect of hiding all CommonParameters from auto-complete. The function below demonstrates the issue.

                          function Get-Foo {

                          [CmdletBinding()]

                          [Parameter()]
                          [string]
                          $Visible,

                          $NotVisible
                          )

                          process {
                          Write-Verbose 'foo'
                          }

                            When sending code to someone, I don't want to have to qualify the post with "if it doesn't work, try the *other* PowerShell...". I know there will be OS-specific modules/commands, but there should *not* be two code bases for the shell itself, or two product names.

                            • Import-Module does not work with binary modules in exe files

                              I've tried putting my commands in an exe module, but could not get this module loaded in PowerShell.

                              1) If I try to load my module as-is, e.g. an .exe file I get "The extension '.exe' is not a valid module extension. "

                              2) If I create a .psd1 manifest and put RootModule = 'MyModule.exe' there I get Object reference not set to an instance of an object.

                              • Add 'StopExisting' as a valid argument for New-ScheduledSettingsSet -MultipleInstances

                                Only Parallel, Queue, and IgnoreNew are supported right now. One would expect that the option available from the Task Scheduler GUI would be available in the powershell interface.

                                Steps to reproduce

                                $a = New-ScheduledTaskSettingsSet -MultipleInstances StopExisting

                                Expected behavior

                                The task's multiple instances policy is set to kill existing tasks before starting another instance.

                                • PowerShell does not fully convert a hashtable passed to a PSCustomObject parameter

                                  When passing a hashtable to a function parameter that expects a PSCustomObject, PowerShell does not fully convert the hashtable to a PSCustomObject type.

                                  function Test-1 {
                                  param(
                                  [PSCustomObject] $Foo
                                  )

                                  Write-Host "`$Foo's type is: $( $Foo.GetType().Name )" -Fore Green
                                  Write-Host "`$Foo is a PSCustomObject: $( $Foo -is [PSCustomObject] )" -Fore Green
                                  Write-Host "`$Foo has these properties:" -Fore Green

                                  foreach ($prop in ($Foo | Get-Member -MemberType NoteProperty| Select -ExpandProperty Name))
                                  {
                                  Write-Host "`t$prop" -Fore Green
                                  }
                                  }

                                  PS C:\Users\dabelc> Test-1 -Foo ( @{ "CustomProp" = "Value" } )
                                  $Foo's type is: Hashtable
                                  $Foo is a PSCustomObject: True
                                  $Foo has these properties:

                                  • Inconsistent Array Initialization Behaviour

                                    Creating an array of arrays as below works well:

                                    $myArray = @(
                                    @(1,2,3),
                                    @(4,5,6)
                                    )
                                    $myArray[0] #outputs 1, 2, 3
                                    $myArray[1] #outputs 4, 5, 6

                                    $myBuggyArray = @(
                                    @(1,2,3)
                                    ,@(4,5,6)
                                    )
                                    $myBuggyArray[0] #outputs 1
                                    $myBuggyArray[3] #outputs 4, 5, 6

                                    I wouldn't expect the order of line break & comma to impact the behaviour of the command / can't find any documentation stating that it should.

                                    • Graphical bug in PSVersion 5.1.16299.248

                                      Hi there

                                      I've never used the powershell very much. Today I discovered this graphical bug in the rendering of the console text output:
                                      https://i.imgur.com/H40F15W.png
                                      This bug was very confusing at first. Then it just kept getting more irritating.
                                      The bug appears when I scroll up and down, at the bottom of the window. Sometimes text gets cut off at the sides too, but only if I change the window width.
                                      I think I remember I had similiar issues years ago on a different computer.

                                      I couldn't find anything related on google. Maybe I used the wrong search terms?

                                      Although totally…

                                      • Remote powershell should not return error for FileSystem validation

                                        SCENARIO
                                        On Machine1:
                                        SCHTASKS /Create /RU SYSTEM /SC ONSTART /TN "Map I drive" /TR "net use I: \\someServer\someShare somePassword /user:someDomain\someUser"

                                        On Machine2 run:
                                        $Script = { Write-Output "Hello world!" }
                                        Invoke-Command -ComputerName Machine1 -ScriptBlock $Script

                                        As a result you get "Hello world!" but also an error
                                        "Attempting to perform the InitializeDefaultDrives operation on the 'FileSystem' provider failed."

                                        The error belongs to I drive which should have been returned as a warning and not error. The invoke does not even use the I drive so why fail on it (we in this case dont even want the invoke to have access…

                                        • BUG: Is it an error or not an error; Inconsistent output and error message

                                          The following codes were extracted to test a simple $arrayName += $NewObject code that kept replacing the entire array with each new $NewObject.
                                          # *** START
                                          $dataArray = @() # Array to store data
