Powershell procedures/cmdlets - MS Project client/Project Server

Powershell is becoming part of any IT-Administrator inventory. If you worked with Project Server 2013 or SharePoint 2013 you are properly avare of many of the many cmdlets available.


Project Server - Powershell cmdlets

For a list of the Project Server cmdlets see this Technet article: http://technet.microsoft.com/en-us/library/ee890097(v=office.15).aspx


MS Project - Powershell cmdlets

Untill recently I was not aware you can access the MS Project client though Powershell. There is actally quite a big API available as you are simply attaching into the VBA/VSTO API.
To connect to the MS Project client simply start up the Powershell ISE and use the following command.
 $Project = New-Object -ComObject msproject.application  

After you are connected the commands are very similar to the VBA counterpart, if you for example want to find the name of all the tasks.
 $Project.Visible = $True  
 $tsks = $Project.ActiveProject.Tasks  
 Foreach ($tsk in $tsks)  
 {  
   Write-Host $tsk.Name  
 }  

Or if you want to open and edit the enterprise calendar.
 $cal_guid = [GUID]"32E5163F-8F5C-472E-9497-F905B3A81E2D"  
 $Project.EditEnterpriseCalendar($cal_guid)  

Basically any VBA call can be migrated into Powershell, see this site for great VBA axamples.

General Powershell Problems

If you get the following error:
 file.ps1 cannot be loaded because the execution of scripts is disabled on this system  
Use the following command to allow the execution policy:
 set-executionpolicy unrestricted  
Note: the above command migth result in the following error:
 set-executionpolicy : Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied. To chang  
 e the execution policy for the default (LocalMachine) scope, start Windows PowerShell with the "Run as administrator" option. To change the execution p  
 olicy for the current user, run "Set-ExecutionPolicy -Scope CurrentUser".  
 At line:1 char:1  
 + set-executionpolicy unrestricted  
 + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
   + CategoryInfo     : PermissionDenied: (:) [Set-ExecutionPolicy], UnauthorizedAccessException  
   + FullyQualifiedErrorId : System.UnauthorizedAccessException,Microsoft.PowerShell.Commands.SetExecutionPolicyCommand  
In this case it can be resolved by adding you account to the permission in a regestry key.
- Click start and run: regedt32
- Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell
- Right-Click the key and select Permissions 
- Select, and add your account, 
- Grant it "Full Control" privileges

Error occurred in deployment step 'Add Solution': Attempted to perform an unauthorized operation.

Received this error today when trying to create a SharePoint solution against a newly created site.


My first problem was the site was configured to use a port which was already used by another web site. Therefore the site could not start at all.

In my case both Default Web Site and SharePoint - 2000 was both using port 2000. Changing the port of Default Web Site and I was able to start the site.

However now I still received the same error message. When browsing the site I realized I did not have access to the site.

Giving access to my user and I was able to deploy the solution.

To sum up this post:
 - Check the site can start
 - Check the site can be browsed
 - Check your user have access to the site

SharePoint 2013 : Cannot connect to the targeted site.

On my Contoso environment I was trying to create a sandboxed solution. I have already configured my app domain and app management services. But when I tried to validate the site I got the following error message.
Error

Cannot connect to the targeted site. This error can occur if the specified site is not hosted on the local system. SharePoint solutions work only with locally-installed versions of SharePoint Foundation or SharePoint Server. Remote development is supported only for apps for SharePoint 2013.
If you search around the internet you will find many people suggesting to change your host file from 127.0.0.1 to the actual IP.

Solution However the solution, at least on a Contoso environment, is to type in the actual IP address in the host file.
(the IP 192.168.150.1 is the special IP for Contoso, I have 2 network adapters)
And do not forget to clear/flush the DNS cache. Now the solution can be created and validates.


PowerShell results size unlimited/truncated - $FormatEnumerationLimit/Width

Ever experienced the problem where you run a Powershell command and you cannot see the whole result because the result is truncated.

Problem: If you for example run the Test-SPsite command you might see something like the following:


Site : SPSite Url=http://atlas/pwa Results : { SPSiteHealthResult Status=Passed RuleName="Conflicting Content Types" RuleId=befe203b-a8c0-48c2-b5f0-27c10f9e1622, SPSiteHealthResult Status=FailedWarning RuleName="Customized Files" RuleId=cd839b0d-9707-4950-8fac-f306cb920f6c, SPSiteHealthResult Status=Passed RuleName="Missing Galleries" RuleId=ee967197-ccbe-4c00-88e4-e6fab81145e1, SPSiteHealthResult Status=Passed RuleName="Missing Parent Content Types" RuleId=a9a6769f-7289-4b9f-ae7f-5db4b997d284, SPSiteHealthResult Status=FailedError RuleName="Missing Site Templates" RuleId=5258ccf5-e7d6-4df7-b8ae-12fcc0513ebd, …
