Custom favicon
It is easy to use a custom favicon, put a ico image into a mapped folder Images and then locate this line in your master page:
<SharePoint:SPShortcutIcon runat="server" IconUrl="/\_layouts/images/favicon.ico" />
```And replace it with your ico:<SharePoint:SPShortcutIcon runat=“server” IconUrl="/_layouts/images/CONTOSO/favicon.ico" />
Increase performance while retrieving data with LINQ to SP
If you are just intrested in getting data, not writing to the source like SubmitChange, you can disable ObjectTracking and increase the performance.
context.ObjectTrackingEnabled = false;
```I found this tip on page 248 in the book "[Sharepoint 2010 as a development platform](http://www.apress.com/9781430227069)"Do an unsafe update in a unified manner
Recently I talked about a WithWeb-pattern as described in Jonas Nilssons blog where you can isolate the disposal logic in one place. Another thing is to isolate unsafe updates:
public static class SPWebExtension
{
public static void UnsafeUpdate(this SPWeb web, Action<SPWeb> action)
{
try
{
Log.Info("Trying to do an unsafe update on a web: " + web.Title);
web.AllowUnsafeUpdates = true;
action(web);
}
catch (Exception e)
{
Log.Error(e);
}
finally
{
web.AllowUnsafeUpdates = false;
}
}
}
```The Log class is my own class which I presented in [my previous post](https://sharepointkunskap.wordpress.com/2011/09/19/a-simple-log/).comments from wordpress

Show Title on Page
If you want to show the page title in another part than defined in your master page just add this tag to your page layout.
<SharePoint:ProjectProperty
Property="Title"
runat="server" />It must be within <asp:Content> tag
Show a presence bubble
There is no built-in sharepoint control for the presence bubble. If you want to add this functionality on your pages you have to add it as html. Here is a sample:
private static int \_COUNTER = 0;
private const string PresenceBubble =
"<a class='ms-imnlink' href='javascript:;'>" +
"<img width='12' height='12' id='imn\_pawn\_{0}' onload=\\"IMNRC('{1}')\\" alt='My SID' " +
"src='/\_layouts/images/imnoff.png' border='0' " +
"showofflinepawn='1' sip='{2}'></a> {3}";
private static string FormatUser(SPUser user)
{
\_COUNTER++;
return string.Format(PresenceBubble, \_COUNTER, user.Email, user.GetSipAddress(SPContext.Current.Web), user.Name);
}Get role assignments of a web or a list
In Powershell you can easily get the permissions in a web or in a list:
$web = get-spweb http://contoso.com
$web.Groups | select Name, Roles > .\\Desktop\\webgroups.txt
$list = $web.Lists.TryGetList("Assets");
$list.RoleAssignments | select Member, RoleDefinitionBindings > .\\Desktop\\assets-roleassignements.txt
```To get all users in all groups run:$web.Groups | Foreach { Write $_.Name; Write “————-”; $_.Users | Select Name; Write “”; Write "" }
Windows 8 preview
I have tested the Windows 8 developer preview. VMWare player 3 didn’t manage it, so I installed VirtualBox and it ran very well. One thing I did was to enable full screen on VirtualBox. Here is the list of features you get if you install the developer preview:
- Windows SDK for Metro style apps
- Microsoft Visual Studio 11 Express for Windows Developer Preview
- Microsoft Expression Blend 5 Developer Preview
- 28 Metro style apps including the BUILD Conference app
Singleton vs static
Have you wondered what to use a singleton object or a class with static methods. Well, here is an awesome comparision of these techniques. Static methods and classes are easy to use, but you can’t them as objects, implement interfaces and have constructors with parameters.

A simple Log for ULS
Here is a simple log which has been inspired of Android Log. It logs to ULS which you can open with ULSViewer, SharePoint Log Viewer.
using System;
using Microsoft.SharePoint.Administration;
namespace Contoso.Intranet.Portal.Utilities
{
public class Log
{
private static readonly string \_CATEGORYNAME = "CONTOSO";
private static readonly SPDiagnosticsCategory \_ERROR\_CATEGORY =
new SPDiagnosticsCategory(\_CATEGORYNAME, TraceSeverity.Unexpected, EventSeverity.Error);
private static readonly SPDiagnosticsCategory \_WARNING\_CATEGORY =
new SPDiagnosticsCategory(\_CATEGORYNAME, TraceSeverity.High, EventSeverity.Warning);
private static readonly SPDiagnosticsCategory \_VERBOSE\_CATEGORY =
new SPDiagnosticsCategory(\_CATEGORYNAME, TraceSeverity.Verbose, EventSeverity.Verbose);
private static readonly SPDiagnosticsCategory \_INFO\_CATEGORY =
new SPDiagnosticsCategory(\_CATEGORYNAME, TraceSeverity.Medium, EventSeverity.Information);
private static void WriteTrace(SPDiagnosticsCategory category, string message, string trace)
{
SPDiagnosticsService.Local.WriteTrace(0, category, category.DefaultTraceSeverity, message, trace);
}
public static void Error(Exception ex)
{
WriteTrace(\_ERROR\_CATEGORY, ex.Message, ex.StackTrace);
}
public static void Warning(string message)
{
WriteTrace(\_WARNING\_CATEGORY, message, "");
}
public static void Verbose(string message)
{
WriteTrace(\_VERBOSE\_CATEGORY, message, "");
}
public static void Info(string message)
{
WriteTrace(\_INFO\_CATEGORY, message, "");
}
}
}A possible improvement can be a custom Area. See an example of ThorstenHans on Github: CustomLogger.cs EDIT: I found an interesting article: How to log to the SharePoint ULS Logs: Clean Debugging and Error Logging broken down into steps written by Philip Stathis.
