[TUTORIAL] Restrict alt-codes from character names

This is also usefull i think:
it will create an function, that checks if the entered string contains only letters and numbers

First execute this to your DB

Code:

---

USE [GunzDB]
GO
/****** Object:  UserDefinedFunction [dbo].[fnCheckString]    Script Date: 11/21/2008 05:23:55 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE FUNCTION [dbo].[fnCheckString](@P_String VARCHAR(500))

RETURNS BIT

AS

BEGIN


DECLARE @V_RetValue BIT

DECLARE @V_Position INT

 

SET @V_Position = 1

SET @V_RetValue = 0 


WHILE @V_Position <= DATALENGTH(@P_String)

          AND @V_RetValue = 0

BEGIN


    IF ASCII(SUBSTRING(@P_String, @V_Position, 1))

            BETWEEN 48 AND 122

        SELECT @V_RetValue = 0

    ELSE

      SELECT @V_RetValue = 1     
  SET @V_Position = @V_Position + 1

END

RETURN @V_RetValue

 

END

---

After that execute this to edit the SpInsertchar stored procedure.

Code:

---

USE [GunzDB]
GO
/****** Object:  StoredProcedure [dbo].[spInsertChar]    Script Date: 11/21/2008 05:26:24 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

/****** Object:  Stored Procedure dbo.spInsertChar    Script Date: 5/10/2007 3:42:11 PM ******/

Not that this is just an edited spInsertChar, if you have you own items/exp/bounty or what ever you need to change it youself.

Finally you got the an spInsertChar that only allow :

Code:

---

This key codes are allowed

0048 = 0 0049 = 1
0050 = 2 0051 = 3
0052 = 4 0053 = 5

Thank me if you found this helpfull

Ty! But if people still use something which is restricted it still gets created but then as NULL?

thanks

DELETE FROM Character WHERE Name = '';

Yep! Thx ^^

Nice Tutorial! :D!

ty, nicee

lol...

I will update the function, soon, the make it better and add an way to allow or disallow some characters.

awesome tutorial Rotana :D

Thanks Rotana, Your rule :).

Nice Tutorial! ;D

wow its hard so many codes

Why does anyone want to restrict it? It makes your name look cool

Offtopic: Why in every thread I see you in, NIRVANAdylan, do you either always go directly against the thread, have to prove someone wrong, or gloat about something that you know?
