'Suppose in the dataset ds you have three tables
'Customer, Order and Supplier. If you want to save
'the Customer table. Below is the code
'Duplicate the table and add it to a DataSet<br />
Dim datatb As DataTable = ds.Tables("Customer")<br />
Dim datatbTmp As DataTable = datatb.Copy()<br />
Dim dsTmp As DataSet = New DataSet()<br />
dsTmp.Tables.Add(datatbTmp)<br />
<br />
'Save data to xml file and schema file<br />

That's a bit of a vague request. What type of applications are you writing? This is a user interface question - so, please, let us know what you technologies you are using for your presentation layer. Are you using ASP.NET or WinForms?

Say suppose I have developed a small application by vb.net, which will insert new record and modify existing record and delete existing record. At the time of inserting new record then primary key, index, unique key, check key can violate for reason like duplicate record, like null value. So how could I capture those errors separately and show proper message for different type of errors to user. At the time of deletion relation can violate say suppose user are trying to delete record from parent table where references are in the child table, at that time foreign key will violate and I want to capture that and show proper message to user.
Please solve my problem giving me the proper exception handling code with comment implement by vb.net.

Since SQLServer is generating the errors, your SQL procedures can return codes to your VB.NET code so you can determine what to do with the errors there.
But, if your code is written properly, your SQL database is setup and the stored procedures that do the actual work are written properly, you should never have to deal with foreign key violations like what your talking about. The only way a user can delete a record from a parent table and violate the child relations is if your code lets them do it in the first place.

I always rely on the old task manager. If you watch closely you'll be able to see how much you are muncing (It works for me in C++,VB and C#) I managed to find memory leaks and so. Other of that I dont know any tools to do the job. I hope this helps.

What it sounds like your looking for is this:
Application Center Test is designed to stress test Web servers and analyze performance and scalability problems with Web applications, including Active Server Pages (ASP) and the components they use.
Application Center Test simulates a large group of users by opening multiple connections to the server and rapidly sending HTTP requests.
It comes with Visual Studio.NET, but I don't know which editions...
