ADO.NET: Tackle Data Concurrency Exceptions Using the DataSet Object

  

ADO.NET provides many techniques for improving the performance of data-intensive applications and for making them easier to build. The DataSet, the hallmark of the ADO.NET object model, serves as a miniature, disconnected facsimile of a data source. While using the DataSet improves performance by reducing expensive trips to the database server, it also introduces the possibility of multiple users attempting to change the same data simultaneously, thereby generating data concurrency exceptions. This article examines the common causes behind data concurrency exceptions and presents techniques for overcoming them.

SSRS 2008 R2 Dataset Field Value Property Data Type not numeric

  
We're building SSRS 2008 R2 reports using SSAS as data sources.  There are several occaissions where the data types of certain dataset field values that represent cube measures are not numeric.  As such, when these fields are used in an aggregate function they throw an error.  Is there a way to remedy this in the dataset? Thanks for your help.

Is there a way to manually or programmatically set the dataset field's data type?  The reason I am asking this question is that I am trying to sum a column of data in a report.  I noticed it is possible to sum a column of data if the datatype of a field in the .rdl file is of type <rd:TypeName>System.Int32</rd:TypeName>. Whereas it is not possible to sum a column of data in an .rdl file when the datatype of a field is <rd:TypeName>System.String</rd:TypeName> . When I create a dataset in BIDS 2008, by default, the dataset gives a field a type System.String.  I need to be able to change the field type to System.Int32 in order to sum the column. My datasource is a web service.  The results returned by the web service method has a datatype of int as follows: <xs:element name="Dollars" type="xs:int" minOccurs="0" /> So it seems the dataset created by the reporting services is giving my webservice a type of System.String. Is there some way of manually changing the type? thanks, Lloyd

Append changes to list data not showing in customised edit form

  
Sharepoint version 3.0 running on Sql Server 2005

My Notes field in a list has the append changes to list ticked so that we can see who added notes and when. This works fine until I attempt to customise the edit form, at this point the previous notes (which had appeared underneath the field) vanish.  How do I get them back? I know they are still there as I can see them when I use the DispForm.aspx view, they dont appear when ever I cuistomise the EditForm.aspx

Assuming I must be missing something obvious as everything else is easy to configure.. Any help or guidance appreciated.
