Disabling the Back Button of IE is bad idea as it is of Client browser you should not change its setting .......
If you do it another way i think it will help you more
BTW why do u want to disable both ?
Thanks and Regards

have a table in sqlserver2005 named emp.
where the coloumns of the emp table are as follows.
empid char(3),
empname varchar(20),
empaddrs varchar(20),
empDOB dateandtime,
emp_no varchar(10)
i want to genertae emp_no as autogenertaed sequencitial number.
where the format of the auto genertaed number for emp_no will be - "id-yyyy-nnnn"
where 1st 2 places are the no of his emp_id i.e 01 or 02 like that
2nd four palces are the year of DOB i.e 2001,or 20005 like this
next four places are the numbers i.e 0001 ,0002 like this(it should be sequential number).
example of auto generated number are-0120010001,0219990002, 0320000003.and so on..
how will i generate this type of sequential no in asp .net (backend vb.net.)
when ever i save a record for a particular employee after giving the data in the front end of their corresponding textboxes, the emp_no should be generated in the database and stored in the emp_no coloumn of emp table.
(i know only how to generate auto num.by setting its identity to true.but dont know what to write in the formula filed so that i can genrate the above type of auto generated number)
ya i have taken emp_id as char(3) so that while i entry the value 01 in the front end it should be taken as 01 not1. if i will take emp_id as int then if i input 01 it wil take 1 only. thats why i have taken as char.
No emp_id is not a sequential no..it can be any number..
thanks in advance

I would seriously suggest that you re-think your approach to this. Make your empid an autogenerated integer, and then use the ToString() methods to write this with leading zeroes to create an emp_no string

Hi
I am trying to access a dll in asp.net/c# but when i try to initialize the object of the class in that dll, i get the following error:
"Object reference not set to an instance of an object"
I have added the assembly using this line:
using assemblyname;
I am creating object with statement like that:
ReportAccess ra = new ReportAccess(); // i get error on the same line.
Can someone help me please by providing me the solution of that problem or by letting me know why i am getting this error or what are the reasons for that error.
Regards

(1) Common mistake when working with code behind classes.
Remember! Codebehinds arn't handled the same way as inline/ pages!
You need to declare EVERY control you want to interact with in the codebehind class
Do this just after the Inherits statement:
<code>Public Class PageOne
Inherits System.Web.UI.Page
Protected WithEvents litOne As System.Web.UI.WebControls.Literal
...</code>
(2) Bad Scoping.
<code>Sub Page_Load(ByVal e As System.EventArgs) Handles MyBase.Load
Private strHello As String
End Sub
Sub Button1_Click(ByVal e As System.EventArgs) Handles Button1.Click
strHello = "Hello!"
End Sub</code>
(3) bad inits and constructs:
Remember, some classes have constuctors
Consider DirectoryInfo:
<code>Sub Page_Load() ....
Dim dirInfo As System.IO.DirectoryInfo
dirInfo.GetDirectory("C:\")
End Sub</code>
In the above example, we've only defined dirInfo *AS* a DirectoryInfo class, we haven't actually created it
So we need to do this instead:
<code>Sub Page_Load() ....
Dim dirInfo As System.IO.DirectoryInfo
dirInfo = New System.IO.DirectoryInfo("C:\")
End Sub</code>
That should do it....
Remember, ALWAYS refer to the MSDN Library when enquiring about classes and their initilisation (sp?) methods.... why trust some "1337 script kiddie!" site when you've got the official reference at http://www.msdn.com ? Or better yet, get the compiled version on CD, don't need to worry about long download times or the constant "was this article of any use to you?" screen.

Hi
I'm trying to create a website with a logon screen and two parts, a public area and a member area. The first page will be the public area. The user then clicks login and is directed to a login page which checks logins with a database. Once the user is logged in they need to be directed to a sharepoint site. Here is my problem...I need the Sharepoint site to use the login info from the login page. I would imagine Sharepoint uses session variables to store the login info, does anybody know what these are?
Thanks

Request.ServerVariables("REMOTE_ADDR")
or
Request.ServerVariables("REMOTE_HOST")
should both give this.

Hi Fred_Smith
i already tried this.If i am running application from localhost
then is shows me default ip address 127.0.0.1.if i am runnign
application using my system name like http://mysysname//add.asp then it
shows me correct ip address. If i am upload the application on my
server then it shows me server ip address but i need user machine access
not server host ip address on which application is running. if i am
running same applcation from different machine it shows me same address
as before.if i am accessing application from different machine then it

OK.. try using:
Dim ip as string = Request.UserHostAddress
|
|
|
|
|
HI
I tried this it gives me following error.
Microsoft VBScript runtime error '800a01b6'
Object doesn't support this property or method: 'UserHostAddress'

Well this is an ASP.NET forum, not VBScript... I suggest you try Googling "client ip address vbscript" and follow up some of the results...
|
|
|
|

I know this is asp.net forum i have implemented same application using asp.net also when i run the application on local machine it gives me correct ip address
and when i am upload this to server and run the page then it also show me
server ip address and server name insted my machine name.
Ok thanx for u r help.

Ths may help: (you'll ned to convert ot VB)
string ip;
ip=Request.ServerVariables("HTTP_X_FORWARDED_FOR");
if(ip==string.Empty)
{
ip=Request.ServerVariables("REMOTE_ADDR");
}
REMOTE_ADDR does not always provide the users IP but rather the ISPs' IP address so first test HTTP_X_FORWARDED_FOR as this one is the real user IP.
|
|
|
|
|
Thanx
I tried that but the result is same as before.Is there
any server setting required for that purpose.
Thanks.
Rahul

Try this code:
Request.ServerVariables["REMOTE_ADDR"].ToString();
