What are the condition to validate a phone number?
Well firstly it has to be a numerical value, can include the following numbers 0123456789 and the plus symbol. +
But what about the following conditions, where do you get this data?
-It has to be in the format [country dial code + area code + phone number]
-It has to be a min and max length
EDIT: also what is the min and max length of a mobile/cell phone number?

View 4 RepliesI'm trying to make filters on gridview. Gridview is bound to SqlDataSourceControl.
The problem is when there is NULL value in DB.
Parameters
Code:
[code]....
Select Statement
Code:
SELECT Name, Phone, email FROM suragch WHERE (firstname LIKE @firstname + '%') AND (phone LIKE @phone + '%') AND (email LIKE @email + '%')
Above example works fine if there is no NULL.
When users want to find email they leave phone field empty and enters the firstname. But my example doesn't displaying email of given user if phone is NULL in db.
I have to make a login form using vb.net. The login form should either accept
Username ID or
Email ID or
Phone number
---- either of one ,and match it with the password of the corresponding record in the user table.
The user table has following column:- U_ID(varchar),mail(varchar),Phone(Number),Password(Varchar)
The form has two textfields - 1. Username
2.Password
And a submit button. If combination is correct I should be redirected to the Index page.
But I don't have to scan through all the columns of the user table to match the password.
(a)If the user enters user_id say- ID 10012 then we should be able to search only the record in the user_id column as it has alphanumeric or varchar data type and match with corresponding password.
(b)If the user enters Email id we should be able to search through the email id column as email id contains "@ and ." sign.
(c)If the user enters phone number then we should search only the phone column as it has numeric datatype.
I have been attempting to find a solution for my phone number formatting problem for 2 hours now and I am not getting any closer. My 10 digit phone number is stored as a varchar(14) without any formatting (just 10 digits).

why the formatting won't work? It just displays the 10 numbers with no formatting.
Is there any solution to retrieve phone no using this dll [URL] ....

Dim s as string = Session("s")
I get a string value for s from the web session. If there is no value in the web session, I get a blank string.However, AFAIK, in C#, I have to have something like the code below to do the same thing.
string s;
try { s = Session["s"].ToString(); }
catch { s = ""; }
