Writing to SharePoint Unified Log
Writing to Windows EventLog sometimes causes issues in SharePoint, especially if using NTLM security. In this situation you might have to allow anonymous write access to the Event log by adding information to a specific registry key (Google if you wish more info on the matter).
As an alternative you can write to SharePoint own log, Unified Log, as described here on msdn.
Btw - I wonder why people in other blogs copy the content from MSDN and place it on their own blogs. What's the idea? It doesn't add any value - it only created confusion as I tend to ask myself. What is the difference?

Office - There has been a network or file permission error
Some of our clients are occationally experiencing the following error in Office "There has been a network or file permission error".
It's hard to find an explanation for the issue but I found this blog quite interesting. Indexing services on Windows Vista could cause the problem.
Another great blog describes ways to solve it for Windows XP SP2 and Office 2007.

ItemAdded - setting values - Microsoft recommendation
If you wish to set property values in an ItemAdded event in SharePoint - you need to create a separate thread that sleeps 10 seconds and then set the value. SharePoint is obviously not a transactional system. Read more in this blog.

More on SharePoint 2010
Doing research on Microsoft SharePoint 2010 I came across various articles and I found this from Lars Fastrup quite useful. Brief and to the point.

SharePoint 2010
The MOSS acronym is going away as Office will be referred to as the client product only. Not certain I buy the reason for this. In fact I view Office as the whole lot - editing as well as storing and managing. But obviously Microsoft don't have the same view - or their customers don't.

MOSS Performance considerations
I just read this blog about performance considerations in MOSS 2007. Especially the section about SPList object is worth reading in detail.
Using the List.Items.Count should be avoided at any costs. It basically send a very complex and expensive SQL query, especially on large lists. If you need statistics use the List.ItemCount instead which uses the statistics information from SQL Server about the list to provide data. No absolutely correct though.

RunWithElevatedPrivileges
We have developed a series of business web services leveraging SharePoint. However, some of our users sometimes ran into security issues when their security level was Contributor.
Luckily I read this article from MSDN which describe that the
new SPSite()
requires privileges above Contributor to work. Running the code in the context of RunWithElevatedPrivileges sovles the problem. Fantastic.

Content Type is still in use
Despite the fact that no files has the a specified content type I still get the error content type is still in use when I try to delete the content type.
I came across this blog that stated that you also needed to look into previous versions of the files as well as files hidden.
Despite the fact that I have done this I cannot delete the ContentType.
I therefore looked into the SQL database in the AllUserData table in the Content database with the following SQL
SELECT *
FROM AllUserData
WHERE (tp_DirName LIKE '%')
AND ((tp_ContentType = ''))
ORDER BY tp_DirName
Then I got a list of files using the content type.
The main issue now is that I cannot figure out how to get rid of the content type from these files. Ideas very much appreciated.

I have
- Checked in documents
- Published them all - i.e. major version
- Previous versions has been deleted
- Emptied recycle bin
- Ensured the content type I wish to delete is not default content type (apart from the fact that SharePoint suggest it to be the new default when uploading documents - which is strange. Maybe this is the reason?)
So what do I do?
Even if I DELETE the files and REMOVE them from recycle bin they still appear in the SQL search. No wonder I cannot get rid of the content type!
Even if I go through all files in the Document Library and explicitly set
oFile.Item("ContentType") = <...>
I cannot DELETE the content type afterwards. Very strange.

Other documents works just fine but a few documents fails. Ideas very much appreciated. Googling find various ideas:
- Open document in Excel, Press Save As, and re-upload - don't help
- MS XML 6.0 de-installed on SharePoint Server - MSXML 6.0 SP2 installed
- Filesize - no relevant - file size is 54Kb
- Save as Excel 2007, then Excel 2003 Fixes the problem - unbelievable

Delete a file from SharePoint
Deleting a file from SharePoint should be fairly easy, i.e. invoking the
SPFile.Delete()
method.
But when invoking this code from a custom web service I get "access denied" error.
Rather than creating my own web service I investigated using standard SharePoint web services. Files can be deleted using web services - as described in the blog where files are deleted from InfoPath.
This MSDN article also describes how to delete files.
Web services are just so much easier to use :-)
