Getting Started with .net and a few questions
Hello I've done some asp and php programming along with various other languages in the past and slowing getting my head around .net.I have a small project of creating a Holiday Booking system on our Intranet and just trying to get the first part to work properly will hopefully get me sorted for the whole project. The Intranet is running on .net 2 and I prefer to use the VB code rather than C#. This is connecting to an SQL server.My initial page that I am trying to create is just for an admin user to view which dates in a table have been specified as Bank Holidays and be able to add ...Try/Catch/Finally Question

I have a new project which has just started. One of the requirements is to generate XML files. Do I have to create schema files?
Does anyone have a tutorial or sample code to help me get started. I have some background using XML, but not in .NET.
How to create a new xml file with XmlDocument? More examples hereSonu Kapoor [MVP] Feel free to ask me any .NET question | Ajax Data Controls Forum
Thanks, this is very helpful.
What do I need to do extra to setup the schema for this xml file? Is the schema really necessary as well?

I am using VS.NET 2005. In previous version of VS.NET, we have Try, Catch & Finally, but why in VS.NET 2005 the Finally omit in VB.NET and it is still using in C#.
I am asking in VB.NET as if we type Try and enter then only Try & Catch came but bydefault Finally not came and we required to manually enter it but but in C# when we type Try, the Catch & Finally byself come.
Thanks in Advance.

When Error accured. Process will run to the CATCH clause then run Finally
But When Error not accured, Process will run to Finally Clause.
So, Error accured or not, Finally Clause certain will to be run it.
I don't know, if this, script in Finally Clause or after Finally's script,
I don't understand the question...
but Finally is executed if the exception is thrown or not.

Can any one tell me if the finally block would be executed in the following example (assuming that dbReader.read() returned false because no records were found).
dbCon = New SqlConnection(myconnectionstring)
dbCom = dbCon.CreateCommand()
strSQL + "SELECT * FROM bookings WHERE ID > 9000"
dbCom.CommandText = strSQL

It'll throw an exception - being in the finally block doesn't exclude your code from throwing exceptions.You can put another try/catch block inside the finally block if you want to trap exceptions there.
Then the exception that is generated in the Finally block will propagate up the call stack until a Catch block is found

http://msdn.microsoft.com/en-us....NET 2005 TRY..CATCH with SQL RAISERROR Not Catching
Is there a reason why the following code does not raise an error in my .NET 2005 application? Basically I have a try..catch in my stored procedure. Then I have a try...catch in my .NET application that I want to display the error message.
But, when the stored proc raisses the error, the .net code doesn't raise it's error. The .NET code DOES raise an error if I remove the try..catch from the SQL proc and let it error (no error handling), but not if I catch the error and then use RAISERROR to bubble-up the error to .NET app. (I really need to catch the error in my SQL proc and rollbac...Getting "Problem in Mapping Fragment starting at line ..." error when trying to create table mappings for table associations in ADO.NET Entity Framework
