Experiments with XNA. Just finished trying to build coverflow, with animation, inertia etc…

Quicknote: Equivalent to SPSecurity.RunWithElevatedPrivileges in standard asp.net (4.0)

Rob Nowik — 08/02/2012 21:57:09

I have an asp.net web app that must execute code under the context of the current user (via identity impersonate, as it needs to call out to various resources). There are some blocks of code, such as writing exceptions to the event log that must run as the app pool account.

In SharePoint, (which has asp.net set up very similar to my web app), there is SPSecurity.RunWithElevatedPrivileges. This ensure a block of code runs as the app pool account. The equivalent in asp.net is as follows:

using (System.Web.Hosting.HostingEnvironment.Impersonate())
{
}

I’m currently debugging WCF, as a reminder, here is an article on how to configure tracing and logging. I simply just put the relevant entries into my web.config and created the folder for my log file to be place in. http://msdn.microsoft.com/en-us/library/aa702726.aspx

Also, here is a link to force self-signed certificates to appear as trusted on a development environment. http://www.robbagby.com/iis/self-signed-certificates-on-iis-7-the-easy-way-and-the-most-effective-way/

SharePoint 2010: Synchronously Deploying Solutions (WSPs)

Rob Nowik — 27/04/2011 18:53:16

When developing larger SharePoint solutions (with multiple developers and environments), we normally write a series of PowerShell scripts to ensure that all our custom functionality and structure can be repeatedly deployed. The problem that commonly arises with this is that SharePoint solution files (wsps) are deployed asynchronously, meaning that later operations in PowerShell scripts can fail. A while ago, i posted a rough article on execadmsvcjobs with SharePoint 2010 (click here to view the original article). I have experimented polling the “Deployed” property of a WSP in PowerShell, however I did not find this robust in some cases.

I have recently hardened my mechanism to ensure that my PowerShell scripts wait synchronously for solutions to deploy / retract as follows (based on a excellent post by Gary LaPointe (see here))

Note that this example assumes a solution to be activated globally (i.e. not at a specific webapp), and that also deploys to the GAC.

        1: Add-PSSnapin "Microsoft.SharePoint.Powershell"

       2: $ErrorActionPreference = "stop"

       3:  

       4: $solutionPath = "C:\DummySolution\DummySolution\bin\Debug\DummySolution.wsp"

       5: $solutionName = "DummySolution.wsp"

       6: $featureName = "DummyWebPart"

       7: $urlToActivateFeature = "http://mywebsite/sites/test"

       8: $webAppUrl = "http://mywebsite"

       9:  

      10: Add-SPSolution -LiteralPath $solutionPath

      11: Install-SPSolution -Identity $solutionName -GacDeployment -WebApplication $webAppUrl

      12:  

      13: do 

      14: { 

      15:     Write-Host "Sleeping for 2 seconds to allow wsp to deploy"

      16:     Start-Sleep 2 

      17:     $solution = Get-SPSolution $solutionName

      18:     if ($solution.LastOperationResult -like "*Failed*") { throw "An error occurred deployment." }

      19:     if (!$solution.JobExists -and $solution.Deployed) { break }

      20: } 

      21: while ($true)

      22: sleep 5  

      23:  

      24: Enable-SPFeature -Identity $featureName -Url $urlToActivateFeature

Quicknote: SharePoint / VS 2010 – Ensuring features activate in the correct order

Rob Nowik — 11/10/2010 18:23:35

Just a quick one – when you have feature dependencies in SharePoint features, the order in which they are activated when F5ing in VS2010 is not controlled by feature dependencies, but the order the features appear in the package (see

Quicknote – Windows 7 Zoom Tool

Rob Nowik — 01/08/2010 15:52:04

It’s been around since release, but i’ve only just started using the Windows 7 zoom tool (windows key and “+” or “-“ key). Pretty cool, although it would be even better if it worked with the mouse scroll wheel.
