I am working on a distributed web service, local client, database app in C# 
..NET 2.0. I have limited experience in the technology, but I am an 
experienced engineer.

I have a data set with a table 'SUMSGroup' In the db I have added two new 
columsn to the table and manually added them to the dataset using the 
designer.

I have rebuilt the app, updated web references and published the web site.

When I run the app, the generated data structures are missing the two new 
columns so that the db stored procedure returns an error. When I examine the 
object from the generated class 'SUMSGroupDataTable' with quick watch at run 
time, the two new columns are missing. But if I use the IDE to go to the 
definition of the data table class, I can see the 2 columns listed in the 
generated code.

What explanation could there be for the inconsistency? My working assumption 
is that I have somehow failed to publish the changes to the web service 
properly.

Thanks,

Andrew

Hi Andrew,

Welcome to MSDN Managed Newsgroup!

Based on my understanding, you first created a strong typed DataSet using 
the DataSet Designer and you're returning the DataSet to your client via 
Web Service. After you added two new columns to the table, you found the 
new columns are not in the DataSet returned to client. 

Please feel free to correct me if I've misunderstood anything.

You once mentioned that you "added two new columns to the tble and manually 
added them to the dataset", do you mean that you simply created two new 
fields in the DataTable's fields list? 

Would you please try following actions to see if they help:

1) Delete the two fields that you manually added previously.
2) Right-click on the table in the DataSet Designer, select "Configure...", 
this will bring up the "TableAdapter Configuration Wizard" dialog again;
3) If you are using SQL statements: if you're using "Select * from ...", 
then you don't have to do anything, simply click Finish; otherwise, you can 
manually edit the SQL to include those two new fields.
4) If you're using Stored Procedures, then you can either create new stored 
procedures or you need to use the DBMS management tool to edit the stored 
procedures there, then choose "Use existing stored procedures" and select 
them.

Hope this helps. Please feel free to let me know if there's anything 
unclear. Thanks.


Sincerely,
