Bring your code 2 life

I recently tried so set some HTML content in a SharePoint list column of type SPFieldMultiLineText. My first approach was this piece of code: SPFieldMultiLineText field = item.Fields.GetFieldByInternalName( "Associated Documents" ) as SPFieldMultiLineText; StringBuilder docList = new StringBuilder(); docList.Append( " " ); foreach (DataRow docRow in addDocs) { DataRow[] parent = dr.Table.DataSet.Tables[0].Select( "DOK_ID=" + docRow[ "DOK_MGD_ID" ].ToString()); if (parent != null && parent.Length > 0) { docList.AppendFormat( " {1} " , parent[0][ "FilePath" ].ToString(), parent[0][ "Title" ].ToString()); } } if (docList.Length > 0) { // remove trailing tag docList.Remove(docList.Length-5, 5); } docList.Append( " " ); string newValue = docList.ToString(); item[field.Title] = newValue; What this code does is to get all associated documents to the main document and to add these docu...

In my *.bdcm BDC-model file I have a section: < Actions > < Action Position ="1" IsOpenedInNewWindow ="true" Url ="http://demo:5555/Company/userdefined/edit.aspx?id={0}&amp;etc=10022#" ImageUrl ="http://demo:5555/_imgs/ico_18_4002.gif" Name ="Projekt in MSCRM bearbeiten" > < ActionParameters > < ActionParameter Index ="0" Name ="ProjectID" /> </ ActionParameters > </ Action > < Action Position ="2" IsOpenedInNewWindow ="true" Url ="{0}" ImageUrl ="http://demo:5555/_imgs/ico_18_4002.gif" Name ="Projektportal öffnen" > < ActionParameters > < ActionParameter Index ="0" Name ="PortalUrl" /> </ ActionParameters > </ Action ...

Recently I was really confused about which type of web part deployment file extension I should use. After some research I figured the following out (which might be interesting for all SharePoint newbies): .dwp is a web part description xml file used prior and up to SharePoint 2007/2010, therefore is still supported .webpart is the newer extension which came with MOSS 2007 So whats the true difference: .DWP: It uses the following namespace xmlns=http://schemas.microsoft.com/WebPart/v2 by default. The markup looks something like: <? xml version ="1.0" ? > < WebPart xmlns ="http://schemas.microsoft.com/WebPart/v2" > < Assembly > AssemblyName(with no .dll extension), Version=VersionNumber, Culture=Culture, PublicKeyToken=PublicKeyToken </ Assembly > < TypeName > WebPartNamespace.WebPartClassName </ TypeName > < Title > DefaultWebPartTitle </ Title > < Description > WebPartDescr...

Today I tried to get a custom Sharepoint web part to work. It was no fun because I had a pretty simple (once you figured it out) and tedious error. I added my custom web part on a standard SharePoint web part page and tried to edit the web part properties. I tried to just click on OK, Apply or Cancel I always got the following annoying message: A Web Part you attempted to change is either invalid or has been removed by another user. After spending a couple of hours, even with an experienced collegue, I finally found an interesting article: http://williamvanstrien.blogspot.com/2010/01/alluserswebpart-and-spwebapplicationapp.html William pointed out that it is a really bad thing to set the ID of a webpart control: "... When you add a control within an .aspx file, Visual Studio automatically add a default 'ID' property to the control. For the default WebPart however this is not needed, the property is actually set when creating a publishing page off this PageLayout. But ...

Today during a debug session this error occurred: Server was unable to process request. 0x80040220 SecLib::CheckPrivilege failed. Returned hr = -2147220960, User: 393528ec-10e4-de11-9707-000c29359a20, PrivilegeId: a3311f47-2134-44ee-a258-6774018d4bc3 Platform It looks like the user with id 393528ec-10e4-de11-9707-000c29359a20 does not have the privilege to do some action on an entity. How do we figure out what privilege it is? Answer is very easy: Open up the MS SQL Server Management Studio and go to the database "ORGNAME_MSCRM", open the table "dbo.PrivilegeBase" and shoot off the following SQL statement: SELECT [Name] FROM [ORGNAME].[dbo].[PrivilegeBase] where [PrivilegeId] = 'a3311f47-2134-44ee-a258-6774018d4bc3' The result was: prvReadEntity Now you know that user with id 3935.... requires the right to read an entity that was used in the request which caused this error.

A customer had the requirement to develop his solution with .NET 3.0 framework. I was already used to the new and nice features of .NET 3.5 framework, especially the class extension feature. A simple example for a class extension would be like this: public class ReverseString { public static void Main() { string s = "Hello World!" ; string r = s.Reverse(); } } static class StringHelpers { public static string Reverse( this string s) { char [] c = s.ToCharArray(); Array.Reverse(c); return new string (c); } } In order to use the same feature under .NET 3.0 you can use the following trick: First create an empty class file (e.g. AttributeExtension.cs) and add this class to your project. Secondly put the following code in that class: using System; namespace System.Runtime.CompilerServices { /// <summary> /// Indicates that a method is an extension method, /// or that a class or assembly contains ex...

As I created a VS2008 Web Setup project I always had to specify the .Net Framework launch condition. I found no way to deactivate this on the UI. To work around this problem I used Orca 3.1 (which also enables support and correct handling of x64 application files). Open up your MSI file and go to Edit->Find and search for: VSDCA_VsdLaunchConditions Delete all rows that contain this word and save the MSI file. Now you should have gone rid of this annoying behavior/feature.

This error occured as I tried to install a custom installer web project, built with VS2008 in 32-Bit or 64-Bit mode on my 64-Bit target system. To get more details on that error, I tried the following command in my console window: msiexec /i /l*vx install.log The log file pointed out the following error: MSI (c) (60:54) [17:00:43:240]: Attempting to enable all disabled privileges before calling Install on Server MSI (c) (60:54) [17:00:43:240]: Connected to service for CA interface.
