Bug with DataSet.ReadXMLSchema
Apparently when using the DataSet.ReadXMLSchema, if you want a string field to have a DefaultValue of "" this is not interpreted correctly when the table is built. The DefaultValue for the field ends up being DBNull.
Here's a sample segment (which was written originally by DataSet.WriteXMLSchema):
Code:
<xs:element name="Bonus" msdata:CaseSensitive="True">
<xs:complexType>
<xs:sequence>
<xs:element name="Name" type="xs:string" />
<xs:element name="Value" type="xs:string" default="" minOccurs="0" />
</xs:sequence>
</xs:complexType>
</xs:element>
Irritating as I will have to go change a bunch of code to cope with this! Heads up!

Well it's a known issue that is fixed in Framework 1.1.

By the way where are you getting the information that this is an acknowledged bug, much less that it is fixed?

Thanks for the info. Sure enough I seem to have version 1.0 installed. I had thought that the service pack took you to 1.1, guess it does not. grumble!
