Validating data in vb net
If ANSI_NULLS is turned on (the default), the IS NULL operator must be used in expressions when testing for null values. Write Line(" Two nulls=", String Equals(a, b)) ' Make them empty strings.
For example, the following comparison always yields unknown when ANSI_NULLS is on: Use the IS NULL or IS NOT NULL predicate to test for a null value. For example, the Territory ID column in the Adventure Works Customer table allows null values. a = "" b = "" ' When comparing two empty strings (""), both the shared/static and ' the instance Equals methods evaluate to true.
Private Sub Compare Nulls() ' Create two new null strings.
Dim a As New Sql String Dim b As New Sql String ' Compare nulls using static/shared Sql String.
NET was developed in direct response to the problems that developers had with classic ASP. NET: Client-Side Validation: When validation is done on the client browser, then it is known as Client-Side Validation.
Since ASP is in such wide use, however, Microsoft ensured that ASP scripts execute without modification on a machine with the . We use Java Script to do the Client-Side Validation.Server-Side Validation is a secure form of validation.The main advantage of Server-Side Validation is if the user somehow bypasses the Client-Side Validation, we can still catch the problem on server-side. NET: Answer: View State is the method to preserve the Value of the Page and Controls between round trips. View State is turned on by default and normally serializes the data in every control on the page regardless of whether it is actually used during a post-back. That means that a new instance of a page is created every time when we make a request to the server to get the page and after the round trip our page has been lost immediately Answer: Caching is one of the most interesting concept and operation in ASP. If you can handle it, you can run any web application by applying the caching concept depending on the requirements. If we get the user input with validation, then chances are that we are sending the wrong data. Whenever the user gives the input, it must always be validated before sending it across to various layers of an application.Global Theme A Global theme is a theme that is applied to all the web sites on a web server and includes property settings, and graphics.
