I’ve been playing around with PoshRSJob and have run into an obstacle that I was hoping someone 

might have some insight into.

I’ve created a function in powershell which manages my downloads from a git (bitbucket) repository, since there can oftentimes be pulls of hundreds of files, I’m using PoshRSJob to improve my download experience. Everything works great, except I can’t seem to figure out how to pass the results from the various runspaces to update my WPF xaml form Progress bar.

Is there something I’m missing when it comes to PoshRSJob that enables this kind of functionality? Here’s an example I tried to put together to see if you wouldn’t mind looking at it?

#if(!(Get-Module -ListAvailable | Where-Object Name -eq "PoshRSJob")){Install-Module -Name PoshRSJob -MaximumVersion 1.7.2.7 -Force}

$AppFiles = 1..100 | ForEach-Object{ New-Object PSObject -Property @{ FileName="File_$_"; Size=$(Get-Random -minimum 2000 -maximum 30000) } }

Hi, 

I need to get the list of groups that a user is a member of within Active Directory. However I need to retrieve the specific set of groups characterised by "zz_' written before the name of the group. I.e. its like a filter for groups.  How do i do this?

So ideally I need something that will allow me to input a username and upon running will output all groups the user is a member of starting with 'zz_'

I am very new to Powershell and what be really appreciative if someone could help me out!

Thanks!

I am attempting to process an Analysis Services tabular model via PowerShell... well, we've tried other methods but none of them worked so this is getting to our last resort and as with everything Microsoft, not going well.

My attempt is to follow this guide

Hello,

I am need to add appointments in other user mailboxes frequently. I need to achieve this using powershell script. 

What is the best way to automate this process using PS ?

Thanks You.

I have a script that searches through multiple XML files for a tag and displays it to the user. Now for two of the files that tag name is the same, so writing a script to display it's contents has been easy. However the remaining few all use different tag names and the tag is not in the same place within the hierarchy. This makes things a little difficult. Now I could manually type in this, but I'm expecting this change over time, so a dynamic approach would be better. 

The tag for these files is "agVal". In the test case it is located in three nodes locations within the xml document.

$xmlDocLoc.base.comp.status.dbsm

$xmlDocLoc.base.comp.statusModeConf.mgiw

$xmlDocLoc.base.comp.statusModeConfCont.mgiw

Is there a way to search the whole of an XML Node hierarchy to find the "agVal" tag?

Hello everybody,

Hi All,

I would like to get help here on setting corporate wallpaper through GPO. Following are the requirement.

• We do have different sized images for corporate wallpaper, which needs to set for different resolution.
• Most users are having dual monitors. Correctly sized wallpaper needs to be set for both monitors.
• All clients are running Windows 7 and servers are running Windows 2012 R2, which means PowerShell scripts can be set as logon script.

I did check many forum topics, but none seems to matching my exact requirement. So, please help.

Thank you 🙂

Hi Friends,

I am very new to Powershell DSC and I would like to implement and test it, so I would like to know more on below points :

1. Why do we need PowerShell DSC ? 

2. What are the PowerShell DSCs advantages over other automation tools ? or any unique property or functionality is highlighted ?

3. When i explored about some tasks using PowerShell DSC, I can do the same with help of GPOs. Example : I can create a good windows patch management environment using DSC (something like automating the patching on servers) This same job can be done by defining policies on GPO. So what would the advantage over this ?

Your answers/suggestions/feedbacks are most welcome

Thanks

I am creating a cmdlet that has 2 different parameter sets.  One parameter set uses a single positional parameter, another uses two positional parameters, all integers.  For some reason powershell doesn't recognize this and errors on me.

Here is some pseudo code that (I think) should work, but doesn't.

Function foo {
    [CmdletBinding(DefaultParameterSetName="A", PositionalBinding=$false)]
    param(

        [Parameter(Mandatory=$true, ParameterSetName="A", Position=0)]
        [int]$varA,

        [Parameter(Mandatory=$true, ParameterSetName="B", Position=0)]
        [int]$varB1,

        [Parameter(Mandatory=$true, ParameterSetName="B", Position=1)]
        [int]$varB2


    )

    process {

        switch ($PSCmdlet.ParameterSetName) {

            "A" {
              Write-Host "Parameter Set A chosen"
            }"B" {
               Write-Host "Parameter Set B chosen"
            }

        }

    }

}

Here is some output, showing that using a second positional parameter doesn't cause it to use set B:

> foo 1
Parameter Set A chosen> foo 1 2
foo : A positional parameter cannot be found that accepts argument '2'.
At line:1 char:1+ foo 1 2+ ~~~~~~~+ CategoryInfo          : InvalidArgument: (:) [foo], ParameterBindingException+ FullyQualifiedErrorId : PositionalParameterNotFound,foo

If I change the default Parameter Set to B, then here is what I get:

> foo 1
cmdlet foo at command pipeline position 1
Supply values for the following parameters:
requiredB2:> foo 1 2
Parameter Set B chosen

If I remove the default Parameter Set, then I get:

> foo 1
foo : Parameter set cannot be resolved using the specified named parameters.> foo 1 2
foo : Parameter set cannot be resolved using the specified named parameters.

What this tells me is that powershell doesn't pay any attention to the number of positional parameters when choosing a parameter set.  It seems like it should be trivial to do so, perhaps there is an option I am overlooking?

I set PositionalBinding to $false because in my script, there are other parameters in each set, and I suspected that it would be necessary to disable PositionalBinding to prevent those parameters from entering the position count.

Just so you understand a use case for doing this... imagine a cmdlet to grab users from a database.  You can either:

1. get-DBUser username
2. get-DBUser firstname lastname

It would be nice not to have to type "get-dbuser -firstname foo -lastname bar" 

Does anyone know how I can make this work?

Hello,

I have a simple script which sets a VM to have an availability set if one is specifies, and does not if there isn't one specified.  The script works, but it throws and error.  I have tried using -erroraction runsilent but I still see an error. I would imagine there is a much better way to accomplish this but I'm new to PowerShell:

#Check to see whether or not an Availability Set will be used.
    $AVstatus = Get-AzureRmAvailabilitySet -ResourceGroupName $RGname -Name $AVset -ErrorAction Ignore
    if ($AVStatus -eq $null)
    {"No Availabilty set was specified.  This VM will be deployed without one."
        $vm = New-AzureRmVMConfig -VMName $vmName -VMSize $vmsize
    }
    else
    {"Machine will be deployed to the following Availability set: $AVset "
        $vm = New-AzureRmVMConfig -VMName $vmName -VMSize $vmsize -AvailabilitySetID "/subscriptions/$subscriptionID/resourceGroups/$RGname/providers/Microsoft.Compute/availabilitySets/$AVset"
    }

When there is no AVset specified in the excel spreadsheet I receive the error below, but ultimately the script works in either case:

Get-AzureRmAvailabilitySet : Cannot validate argument on parameter 'Name'. The argument is null or empty. Provide an argument that is not null or empty, and then try

Hello!

I am trying to bulk delete computers from Active Directory using a PowerShell script. The list I have, however, only has partial names. 

e.g. my list is like this: 

199255 

326955 

128793

but the full computer names are like "BLDG199255ROOM" or "BLDG326955ROOM"

I am trying to use this list to delete the machines from active directory. Here is what I've mustered so far (I'm very new to PowerShell, and really wanting to learn):

$computers = get-content C:\computers.txt | Get-ADComputer -Properties ProtectedFromAccidentalDeletion
$computers | Set-ADObject -ProtectedFromAccidentalDeletion $false
$computers | Remove-ADComputer

I need to do the following.    Machine abc does not have Office installed locally.   A user who is logged into machine abc goes to a network share and double clicks on an Office doc (.xlsx, docx etc....)   I need that document to launch in Office.Live.com

Now, I can modify the File Association and point any .xlsx or docx file to run a custom PowerShell Script.  This PowerShell script looks like this:  

(if an Excel file was clicked on.......)

if (Test-Path  "C:\Program Files\Microsoft Office 15\root\office15\Excel.exe"){start-sleep -m 1}
ELSE {cmd.exe /c "C:\Program Files\Internet Explorer\iexplore.exe" "https://office.live.com/start/Excel.aspx?"}

My issue is this does not open the document that was actually clicked on.    How would that be done?   So the file could be something like this:    \\Server\Share\SubFolder\SubFolder2\Expense Report for January 2017.xlsx

How would you launch that in Office.Live?
