After some time, I was making a query to the SharePoint webservice, for some reports I was making – by the way, I’m using Enesys RS Data Extension for this job, I can recommend that product, it makes it much easier to write queries to SharePoint lists.
So I noticed that the columns made with Chris’s approach was not included in the response!…. Strange…

I was able to access the fields via the Object Model without problems. 

It took me quite some time to figure out, but eventually ended up compairing the SchemaXML to a regular lookup column, made in the SharePoint UI.
And there were some differences.

On my custom made lookup columns there was a namespace attribute.
After removing the attribute in the FeatureActivated method everything is running as it should.

Thanks to Frederic from Enesys for pointing me in the right direction!

I made a typed dataset for my tables, defining the date columns as ‘xs:date’
To remove the timestamp in the report, I used FormatDateTime(Fields!OrderDate.Value, 2), and everything was fine….. Untill the users start complaining, that the date columns where not formatted as date in the exported excel sheet.

The solution is to use the ‘Format’ property of the field, here you can specify the formatting for dates.
For example =”dd/MM/yyyy”. Here you can also make an expression to handle different language options etc.
This approach preserves the date format in exorted excel sheets.

The project is still in it’s starting fase, but it’s simple and nice.

Pretty fast you will discover, that some of the often used characters when coding, are not available right away.
For example curly brackets, square brackets and other shortcuts connected to the ‘Alt Gr’ key.

Fortunately you can use Ctrl + Alt – and you’re ready to go…. almost…

So far, I haven’t been able to use backslash (on my danish keyboard, that involves Alt Gr)
If anyone has found a solution – please leave a comment!

But by default Windows Mobile won’t let you install custom certificates.
So we need to do a little registry hack (remember – this is just a windows box).

• Download the utility RegEditSTG – a registry editor for Windows mobile.
• Change the registry key: HKLM\Security\Policies\Policies0001017 = 144
  And remember the original setting – we must revert i later 
• Now you will be able to install your custom certificate.
• Now change the registry key to it’s original value.

Stramit SharePoint Caml Viewer lets you create a view via the SharePoint GUI, and then you can go behind the scenes with Stramit SharePoint Caml Viewer, and see the xml markup query.

I downloaded the trial, and spend about 10 minutes installing it, and it worked right away.

Very easy, and really powerfull tool…

The tricky thing is that SharePoint site is public available to known users, but how to handle authentication with Reporting Services??

Well – Microsoft fixed that for you in SP2 for SQL Server 2005, where they introduced a feature called Reporting Services in SharePoint Integration Mode

I’m still in the early adoption fase, but it looks pretty promising to me – decide for your self…

When you use the DataReader, you usually end up with a lot of places where you access the content of your datareader like this: ‘dr.GetString(8)’
The problem is that after some time you can’t remember which fields actually had number 8 in the array, and you have to go to your SQL statement to find out.

I came across the method “GetOrdinal” on the DataReader object and wondered what was the purpose for that, and after a little googling, I found out, that it actually solved one of my everyday problems (a small one, but anayway;))

So here is how it works.
In the scope of ‘while(dr.Read())’, you call the method with the DB2 field name, and it returns an integer telling the index of the field in the datareader array: 

int db2CustomerNo = dr.GetOrdinal(“ODKUND”);

and then in your code, you can access the field using your assigned integer like this:

dr.GetString(db2CustomerNo)

No rocket science – just a little trick, that makes your day a little bit easier;)
