My Software Engineering Universe


clock October 1, 2011 02:56 by author Jeroen Derde

Found out today that the behaviour of the PublishingWebControls:EditModePanel changed between MOSS2007 and SP2010.

Apparently,now in SP2010, you need the EditItem Permission to be able to see what is in an EditModePanel even if the PageDisplayMode attribute is set to "Display".

So basically it works like a SPSecurityTrimmedControl


<SharePoint:SPSecurityTrimmedControl PermissionsString="EditListItems" runat="server"> 

This behaviour has been changed back to 2007 behaviour as of SP1 for Sharepoint 2010

Visio 2010 XSD

clock June 6, 2011 23:28 by author Jeroen Derde

About a week ago Microsoft published the XML Schema Definition (XSD) files for the Microsoft Visio 2010 XML Drawing (.vdx) format. This schema is also known as DatadiagramML.
This should make it alot easier to use the visio file to generate code based in the visio file.

The DatadiagramML Schema for Visio 2010 consists of three .XSD files:

  • visio.xsd is the core schema used by Visio 2003 and later
  • visio12.xsd is the set of extensions used by Visio 2007 and later
  • visio14.xsd is the set of extensions used by Visio 2010

More information about the schema is available in the Visio 2010 XML Schema Reference on MSDN.

New job at e-office

clock April 9, 2011 00:23 by author Jeroen Derde

April 1st I started my new job at e-office.  e-office focusses on Human software, and does this using Microsoft, IBM and Google technology.
Human sofware can be seen as 'messaging', 'collaboration', 'enterprise 2.0', 'unified communications', 'user experience' and 'mobile'.
It does however not stop at the technology, because at e-office we believe that people and organisations are an equal part of the equation.

I've joined the SharePoint team at e-office, and I'm already very excited about the upcoming projects that I have seen.

You can follow e-office on:





Sharepoint and the iPad

clock February 9, 2011 21:29 by author Jeroen Derde


I've been using the iPad for a while now, and regulary find myself accessing my companies SharePoint intranet.
First I just used the iPad's browser, but found that touch input is a bit cumbersome at times and the screen realestate is a bit small on the iPad.
The screen realestate issue could be fixed with some nice orientation enhancements for SP2010 (, but that would still leave me with my navigational issues.

To make my life a bit easier I did some research into the available iPad apps that make navigating and using SharePoint easier.

I currently use SharePlus lite. This is the free version of SharePlus.
The Pro version will currently set you back:
 - USD 14,99 or
 - EUR 11,99

SharePlus features I really like are:

  • Big buttons that make for easy navigation
  • Pro version is a 1 time buy for all your iOS devices
  • ISA and ForeFront authentication support
  • Add, edit & delete list items, such as: tasks, pictures, contacts, custom lists, discussion boards and documents while connected. Edit includes Check In, Check Out & Discard CheckIn support (pro only).
  • Send documents by email.
  • Browse data by view in online mode, respecting server defined list views, with ordering and filtering settings.
  • SSL Support
  • Connects to WSS 3.0, MOSS 2007, SP2010, and all editions of SharePoint Online (BPOS included), as long as they use windows based authentication and not forms based. Form based is now supported

Other iPad applications for SharePoint I found are:

Fillament (this is the next one I will be trying)

Haven't tried this yet, so no actual experience

  1. Also has a lite and a pro version
  2. Pro version is USD 12,99 or EUR 10,49
  3. Pro: bit cheaper, supports form based authentication, SSL self signed certificate support
  4. Con: irritating music in demo video :), data editting only in pro version
  5. Site:
  6. Video:



  1. Free
  2. Pro: Free, Dashboard function
  3. Con: version 1.0, not as advanced as the other two

UserControls in WSPBuilder Project

clock May 13, 2010 02:14 by author Jeroen Derde

WSPBuilder extensions for Visual Studio are great. If you use WSPBuilder to create webparts however, you might have run into the fact that by default Visual Studio does not allow you add Web User Controls to a WSPBuilder project.

At the project I'm currently working on, we use WSPBuilder and usercontrols for the visual part of the webparts we create. To make life a bit easier we altered the projectfile of our webparts project.

If you change:




Visual Studio wil think it is now a WebApplication, and will allow you to add usercontrols by using Add --> New Item on your WSPBuilder project.

MOSS .net Framework 3.5 SP1 upgrade issue

clock March 15, 2010 23:00 by author Jeroen Derde

Today at a client, we stumbled upon a problem when updating MOSS2007 SP2 with .Net Framework 3.5 SP1. Everything seemed to work fine, but Search & indexing was not working anymore. The error log showed the following: EventID 6482 - Application Server Administration job failed for service instance Microsoft.Office.Server.Search.Administration. SearchServiceInstance
Indexing and serving search queries is handled by diffetent servers in the clients environment.

After a bit of googling and bingging we foud this exelent post by Andera Glaser that decribes the problem and the solution to the problem.

First Sharepoint 2010 NEN 2082 certified project

clock March 5, 2010 00:50 by author Jeroen Derde


Together with 3 colleagues from QNH Business Integration I am currently finishing implementing a already NEN 2082 certified project based on SharePoint 2010.
When SharePoint 2010 hits RTM there will be another audit for this version of SharePoint, because currently the pre release version has been certified.

NEN 2082 is a Dutch standard which is similar the DoD5015 and MoReq standards.

This project was done for the Gemeente Nieuwegein, which is a Dutch local Government.

For this project we have also been nominated for the “Innovation of the year” award:

SharePoint 2010 Workflow

clock February 25, 2010 20:24 by author Jeroen Derde


A collegue created a SP2010 workflow in visio, and imported it into SharePoint Designer 2010.
His flow used the following actions: 

  • AddListItemPermission
  • InheritListItemPermissions
  • RemoveListitemPermission
  • ReplaceListItemPermissions

SharePoint Designer 2010 throws an error when he validates the workflow (check for errors) or tried to deploy it.

The error (for searchablility):
This workflow action is not supported in this region of the workflow.
It can only be inserted in certain types of blocks.


SharePoint Designer does not show the actions as available.
After a bit of searching we found that these actions can only be added when inserted in an Impersonation Step.
This is logical as the impersonation step runs as the author of the document, in stead of the workflow starter.

Hope this is helpful.

Click the contenttype together in MOSS and copy the xml from this tool into your sharepoint solution.

This tool works with SP2010 beta.


Don't set your SharePoint trustlevel to full

clock November 10, 2009 00:29 by author Jeroen Derde

A really nice (and funny) article why you should not do this, by Tyler Holmes.

I came across this article because we had an assembly containing a feature reciever that would cause an error when executed.
Assemblies containing feature recievers should always go in the GAC (by design), but we where creating a custom policy.

So, I agree with Tyler that custum policies are still preferable, but when you have a dll that contains a feature reciever, you should just put it in the GAC.
