The user does not exist or is not unique.

I saw this problem a few times but when I went to user profile, I can see the user is there and all the information is right. But if you go to WSS_Content db and run

select * from userinfo where tp_title like ‘user%’

I found the tp_login data is different from the user who has problem. The problem with this, is that the tp_Login column in the UserInfo table for every site collection in which Margie has permissions, is cached with her previous NT Login Name. There is also no way to update this information with a SPUser object from the SharePoint object model, and SharePoint does not synchronize this from Active Directory once the users is added to a web in the Site Collection.

The only time that SharePoint will automatically update the tp_Login column, is if the users is completely removed from the site collection. The tp_Deleted column is then set for the user in that site collection. On the next occurrence of the user being added to a web, we gather the current information from the domain. You can however, re-sync SharePoint with the current information without removing them completely from the site collection by using SPUserUtil

For a single user you can use
stsadm.exe -o migrateuser -oldlogin MYDOMAIN\prhranki -newlogin MYDOMAIN\LUHRANKI -ignoresidhistory

If you need to do a batch of users, I personally think WSSUserUtil and SPSUserUtil is the way to go.

Inserting line breaks into text using Rules in InfoPath

If you are using solution from http://blogs.msdn.com/infopath/archive/2005/03/04/385577.aspx. You need to make sure that your textbox is formatted to be able to display paragraph breaks. To do this double-click on the text box control, go to the Display tab, and check the checkbox labeled “Allow paragraph breaks”.

After this, your code should work, but if it still doesn’t try using “\n” instead of the System.Environment.Newline.

There is another way to do that.

SharePoint Cascading Drop Down List

A very good solution to have. Check the following blog, describing how to configure the list correctly http://sharepointsircar.blogspot.com/2009/02/cascading-dropdownlist-custom-field.html.

Hide Advanced Search Link from SmallSearchInputBox

Search Box in the chrome works differently then any other place in the product. If you look at default.master(%Program Files%\Common Files\Microsoft Shared\Web Server Extensions\12\TEMPLATE\GLOBAL) file you can find the following

So basically the search box is hosted by delegate control. Essentially the idea here is that WSS comes with a search box which supports certain features. When you install MSS or MOSS a newer Search box feature is installed with higher priority) and the delegate control know to pick this up. You can read more about the delegate controls here:

Create a new feature that will put the search box with correct properties that you want: Follow the steps in

http://msdn2.microsoft.com/en-us/library/ms470880.aspx

In step 3 in the linked article instead of using what is specified in the article use this

<?xml version="1.0" encoding="utf-8" ?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
    <Control
        Id="SmallSearchInputBox"
        Sequence="21"

ControlClass="Microsoft.SharePoint.Portal.WebControls.SearchBoxEx" ControlAssembly="Microsoft.SharePoint.Portal, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c">

      <Property Name="GoImageUrl">/_layouts/images/gosearch.gif</Property>

      <Property Name="GoImageUrlRTL">/_layouts/images/twg/goRTL.gif</Property>

      <Property Name="GoImageActiveUrl">/_layouts/images/gosearch.gif</Property>

      <Property Name="GoImageActiveUrlRTL">/_layouts/images/goRTL.gif</Property>

      <Property Name="SearchResultPageURL">/_layouts/osssearchresults.aspx</Property>

      <Property Name="UseSiteDefaults">true</Property>

      <Property Name="FrameType">None</Property>

      <Property Name="DropDownModeEX">ShowDD</Property>

      <Property Name="ShowAdvancedSearch">false</Property>

    </Control>
</Elements>

You do not need to do step 4 and 5 in the linked article. Note that I have changed the sequence number to 24 which will ensure that your control is what the delegate control render. It should be between 0-25 as the OOB search box has a sequence 25.

The property that I added is highlighted in green.

The value is ShowDD by default if nothing is set.

Use “Velocity” Session

In .Net 4.0, there is a new way to store the cache. It is Velocity and current on CTP.

Velocity is a custom session provider that can replace the ASP.NET default session provider. See this blog for more details

Unable to see default Silverlight control in Toolbox
