Problem creating DataSet structure from xsd: The same table (...) cannot be the child table in two nested relations.

Suppose we have an object hierarchy in XSD.
For example, let us take Control, Label, TextBox and LinkLabel windows
Each control has some properties which are represented as elements.
Some of the elements are of complex types as well, like bounds - of type
(See full example in the bottom of the letter.)

DataSet.ReadXMLSchema fails to parse such XSD file.
The problem is caused by complex type as an element of the base type of
(In the example this type is called rectangle.)
More specifically, when parsing the example XSD file DataSet.ReadSchema
1. Create table for "allowedObject" complex type.
2. Create table named "label" for label complex type.
3. Create table "bounds" for bounds element of complex type "rectangle".
4. Create table "textBox" for textBox complex type.
5. Try to create "bounds" table for bounds element of complex type
"rectangle" and fail because this table already exists.

From my point of view is a serious restriction of functionality.
I am using Visual Studio 2002 and .NET Framework 1.0.
Is it fixed in Framework 1.1?

Can you think of a workaround for this problem?
Please do not suggest to inherit control from rectangle, because in real
schema I have more then one complex property.
I can add "font" to this example to illustrate it.

Thank you.

How do I link data workbooks to a create a graph?

I want the final result to be charts that show the relationship between staffing levels, incoming call volume, and time of day. hi Andrea, Many things are possible in Excel & I'd say that you could probably find a way of linking all the workbooks.

Hi, I have 20 million (5 type record ids -- 2-3gb)records need to be loaded into a table daily. Is it a good idea to have a a patiotion table seperated by reciord type id. 1. It will be faster for retrieval in performance? 2. What is the drawbacks ot have a partitioned table instead of regular table? Thanks, Mecn My opinion is 1) It will be fatser if the user searches on particular typeid , if he/she searches on typedid 1 and 5 then it will 'scan' two partitions 2) You have to have some experience to maintain partitons "Mecn" <> ...
