Example (which is faster or best practice): Dim result1 As String = 10 & "em" Dim result2 As String = 10.ToString() + "em"

• What's the Microsoft Ajax equivalent to jquery.ajaxSetup() or .ajaxError()?

  - by Seth Petry-Johnson

  I have an ASP.NET MVC site that uses both Microsoft Ajax [Ajax.BeginForm()] and jQuery to make asynchronous requests. I want to configure both frameworks such that a generic error handler is automatically attached if the developer does not explicitly specify a failure callback. In jQuery I can accomplish this with either .ajaxSetup() or .ajaxError(). What is the equivalent in the Microsoft Ajax client library?

  I have 2 integer fields that represent dates in the YYYYMMDD format. What is the best way to subtract 2 of these fields to get the correct # of days between them?

I know I need to convert the integer fields into date formats but everything I have tried either throws an exception or doesn't work correctly. What am I missing? Answers in vb.net please

How do I check the existance of fields in web.config, and in case of not finding it, how do I add it permanently to the web.config ? Thank you
