Question

I have a powershell script that I am trying to add webparts to a sharepoint page automatically. The script below is wrapped in a FOREach-Object and it works fine on the first iteration however on the second itereation it is returning some unwanted information to the powershell screen (and logs I am creating).

I am looking for a way to prevent that from returning anything other than the write-host statements. I originally thought it might be an exception however It looks like the web parts are still being added with no issue and I can’t find any reference to an exeption in the return info.

Here is what I have thus far:

$addCsv | ForEach-Object{

            $tempwebURL = $_.'SiteURL'
            $pageUrl = $_.'Page'
            $varWebPartZone = $_.'WebPartZone'
            $varChrome = $_.'Chrome'
            $varTitle = $_.'Title'          
            $varPosition = [int]$_.'Position'

            #get current site
            $tempweb= Get-SPWeb -Identity $tempwebURL
            Write-Host ("Adding Web Part to :"+ $tempweb.Title)

            #add webpart
            [System.Xml.XmlTextReader]$oxmlReader = new-object System.Xml.XmlTextReader("Path removed");
            $webpartmanager=$tempweb.GetLimitedWebPartManager( $pageUrl,  [System.Web.UI.WebControls.WebParts.PersonalizationScope]::Shared)    
            [System.Web.UI.WebControls.WebParts.WebPart] $oWebPart
            $err = ''
            $oWebPart = new-object $webpartmanager.ImportWebPart($oxmlReader,[ref]$_.Exception.Message)
            $oWebPart.Title = $varTitle
            $oWebPart.ChromeType=$varChrome
            $webpartmanager.AddWebPart($oWebPart, $varWebPartZone, $varPosition)| Out-Null 
            $oWebPart.Dispose() 
            $oxmlReader.Close()
            $webpartmanager.Dispose()
            $tempweb.Dispose()
            $num++

}

Below is the information being printed to the screen which I do not want:

I also welcome any “you could do this better by…” comments. Thanks again.

Answer 1

My guess would be that the following line is the culprit:

[System.Web.UI.WebControls.WebParts.WebPart] $oWebPart

In the first iteration this won’t do much, it’s just a cast of $null. But in later iterations it retains the value of the previous iteration and outputs it. You don’t need that line anyway as it does nothing.
