When you use a relative path, it is based off the currently location (obtained via Get-Location) and not the location of the script.  Try this instead:

    $ScriptDir = Split-Path -parent $MyInvocation.MyCommand.Path
    Import-Module $ScriptDir\..\MasterScript\Script.ps1

In PowerShell v3, you can use the automatic variable `$PSScriptRoot` in scripts to simplify this to:

    # PowerShell v3 or higher

    #requires -Version 3.0
    Import-Module $PSScriptRoot\..\MasterScript\Script.ps1

The new Method for this is `$PSScriptRoot`

    Import-Module $PSScriptRoot\Script1.ps1

Nice little one liner.

This worked for me:

&lt;!-- language: lang-powershell --&gt;

    $selfPath = (Get-Item -Path &quot;.&quot; -Verbose).FullName
    $dllRelativePath = &quot;........&quot;
    $dllAbsolutePath = Join-Path $selfPath $dllRelativePath
    Import-Module $dllAbsolutePath

I am working in a small organisation, only two developers and we use Mercurial version control `tortoisehg-2.2.2-hg-2.0.2-x86`. I am new to mercurial.

Consider `programmerA`, `programmerB`.

In `programerA` machine I created a repository and a client with name `&quot;EFSL&quot;`.
`programmerB` is simply a client with name `&quot;Uthaya Kumar&quot;` pointing at `programmerA` machine repository.

When I am pulling change set in `programmerA` machine it creates a new branch,
and it also shows `&quot;Not a head revision!&quot;` error in both working directory and repository.

In `programmerB` it is fine.

Please see the screenshots below.

Thanks in advance.

&quot;Not a head revision!&quot; in Mercurial Hg

I have a Spring project for a small web app set up in Intellij IDEA.

It uses JPA on top of Hibernate for the persistence layer. The datasource (MySQL) is defined in Spring application context :

&lt;!-- language: xml --&gt;

        &lt;!-- Values are configured via the property override --&gt;
        &lt;bean id=&quot;myDataSource&quot; class=&quot;org.apache.commons.dbcp.BasicDataSource&quot; &gt;
            &lt;property name=&quot;driverClassName&quot; value=&quot;&quot;/&gt;
            &lt;property name=&quot;url&quot; value=&quot;&quot;/&gt;
            &lt;property name=&quot;username&quot; value=&quot;&quot;/&gt;
            &lt;property name=&quot;password&quot; value=&quot;&quot;/&gt;
        &lt;/bean&gt;

The actual value are read from a properties file and injected at runtime by Spring using the property-override mechanism.

And then the datasource is injected into the entity manager factory in the same application context:

&lt;!-- language: xml --&gt;

        &lt;bean id=&quot;entityManagerFactory&quot; class=&quot;org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean&quot;&gt;
            &lt;property name=&quot;dataSource&quot; ref=&quot;myDataSource&quot;/&gt;
        &lt;/bean&gt;

Finally the entity manager injected into the DAOs using an annotation:

    /**
     * Shared, thread-safe proxy for the actual transactional EntityManager
     */
    @PersistenceContext
    private EntityManager em;

It all works fine when I build and deploy it to Tomcat, but Intellij&#39;s JPA validation doesn&#39;t seem to understand where to get the datasource from. 

In my entities, the tables&#39; names and columns&#39; names are underlined in red and the validation message is &quot;cannot resolve table&quot; or &quot;cannot resolve column&quot;:

    @Entity
    @Table(name = &quot;domain&quot;)
    public class Domain extends AbstractAgendaEntity {

Int this example, it&#39;s the `&quot;domain&quot;` part that is not considered valid.

I have manually configured my database in the &quot;Database&quot; tool window, I can see my tables and perform SQL queries in the console.

How can I tell Intellij to use this datasource to resolve table names for my JPA entities?

I have directory structure that looks like this:

    C:\TFS\MasterScript\Script1.ps1
    C:\TFS\ChildScript\Script2.ps1

What i want to do is specify the relative path in Script2.ps1 to look for Script1.ps1 in the directory hirearchy.

This is what i tried in Script2.ps1:

    Import-Module ../MasterScript/Script1.ps1

but it does not work and says it cannot find the module.

If i say `Import-Module C:\TFS\MasterScript\Script1.ps1`, it works fine.
What am i missing here?

In PowerShell, how do you get an object&#39;s property value by specifying its name (a string)? I want something like the following:

    $obj = get-something
    
    # View the object&#39;s members:
    $obj | gm
    
    # I could retrieve a property by doing so:
    write-host $obj.SomeProp
    
    # But for many purposes, I would really want to:
    write-host $obj | Get-PropertyByName &quot;SomeProp&quot;

Is there something similar to &quot;Get-PropertyByName&quot; in PowerShell?

I&#39;ve found some interesting behaviour in PowerShell Arrays, namely, if I declare an array as:

    $array = @()

And then try to add items to it using the `$array.Add(&quot;item&quot;)` method, I receive the following error:

&gt; Exception calling &quot;Add&quot; with &quot;1&quot; argument(s): &quot;Collection was of a fixed size.&quot;

However, if I append items using `$array += &quot;item&quot;`, the item is accepted without a problem and the &quot;fixed size&quot; restriction doesn&#39;t seem to apply.

Why is this?

Array.Add vs +=

According to [get-help about_Functions_CmdletBindingAttribute][1] 

&gt; The CmdletBinding attribute is an attribute of functions that makes them operate like compiled cmdlets

We can use it on the top of our scripts.  What is the function in this case? An internal implicit &quot;main&quot; function called by the PowerShell engine for all its inputs?

Regarding this syntax:

    [CmdletBinding(ConfirmImpact=&lt;String&gt;,
                         DefaultParameterSetName=&lt;String&gt;,
                         HelpURI=&lt;URI&gt;,
                         SupportsPaging=&lt;Boolean&gt;,
                         SupportsShouldProcess=&lt;Boolean&gt;,
                         PositionalBinding=&lt;Boolean&gt;)]

What are we doing?  Instantiating a `cmdlbinding` object and passing an argument list to its constructor?  This syntax can be found in `param()` - for example: `[Parameter(ValueFromPipeline=$true)]`. Does this syntax have a particular name, and can it be found elsewhere?

Lastly, are we able, as simple PowerShellers, to mimic this functionality and modify the behavior of scripts by setting an attribute?

I have a folder where I need to delete all files and folders except a small list of files and folders.

I can already exclude a list of files, but don&#39;t see a way to exclude a folder and its contents.

Here is the folder structure:

    |-C:\temp
     \-C:\temp\somefile.txt
     \-C:\temp\someotherfile.txt
    | |-C:\temp\foldertodelete
       \-C:\temp\foldertodelete\file1.txt
    | |-C:\temp\foldertokeep
    |  \-C:\temp\foldertokeep\file2.txt

I want to keep somefile.txt and the folder foldertokeep and its content.

This is what I have right now:

    Get-ChildItem -Path  &#39;C:\temp&#39; -Recurse -exclude somefile.txt | Remove-Item -force -recurse

This really does not delete somefile.txt. Is there a way to exclude folder foldertokeep and its content from the delete list?

How can I open up a file in Notepad++ from the Powershell command line?

Open Notepad++ from PowerShell

I&#39;m trying to write a very simple PowerShell script to give me the total number of items (both files and folders) in a given folder (`c:\MyFolder`).  Here&#39;s what I&#39;ve done:

    Write-Host ( Get-ChildItem c:\MyFolder ).Count;

The problem is, that if I have 1 or 0 items, the command does not work---it returns nothing.

Any ideas?

I need to create a new local user account, and then add them to the local **Administrators** group. Can this be done in PowerShell? 

EDIT:

    # Create new local Admin user for script purposes
    $Computer = [ADSI]&quot;WinNT://$Env:COMPUTERNAME,Computer&quot;
    
    $LocalAdmin = $Computer.Create(&quot;User&quot;, &quot;LocalAdmin&quot;)
    $LocalAdmin.SetPassword(&quot;Password01&quot;)
    $LocalAdmin.SetInfo()
    $LocalAdmin.FullName = &quot;Local Admin by Powershell&quot;
    $LocalAdmin.SetInfo()
    $LocalAdmin.UserFlags = 64 + 65536 # ADS_UF_PASSWD_CANT_CHANGE + ADS_UF_DONT_EXPIRE_PASSWD
    $LocalAdmin.SetInfo()

I have this, but was wondering if there is anything more PowerShell-esque.

I am writing a script to use multiple plink (PuTTY) sessions as a Windows version of clusterssh.  I am stuck however because I want to open multiple Powershell windows from powershell.  When I type the command for powershell, it opens a new session.  This is similar to typing bash in bash. I want multiple physical windows opening.

I tried -windowstyle as well as the other args to no avail.  I was wondering if there is a way you know of.  I really appreciate your help.  I looked and didn&#39;t find anything already here.  Thanks for your time.
