I am not able to add rows n values to data gridview programmatically(without binding to datasource)..I think the problem is because the rows are assigned 'databound' property...Any alternative for 'databound' so that i can add values programmatically?

Hi,

if (FileUpload1.HasFile == true)
{
FileUpload1.SaveAs(Server.MapPath("~/AdminSection/Attachment/Emp/" + FileUpload1.FileName.ToString()));

}

If file is not blank, then this code work fine.

but if the file is blank then it doesn't.

Is there any Solution for this.

or tell me how to check whether file (File can be of any type) is blank or not.

Thanx. Smile | :)

Check FileUpload1.FileBytes.Length or FileUpload1.FileContent.Length for validating the file size. Big Grin | :-D

AFAIK Normal AdRotator dont allow you to do...

You need to add javascript addbanner to your site I think. Check this:

How to Avoid Session hijacking

Hi All,

I have a requirement from one client to change the sessionid for each user to avoid session hijacking.

So i did that as suggested by below link.

http://palisade.plynt.com/issues/2007Feb/asp-session-cookies/

Now they asking to binding the session id to the client machine ip.

My application developed using classic ASP.

How can i achieve that, please help me....

What is the problem with this. Each computer generates its own session with different session id.

If you want to allow the IP based authentication including user id and password, so that the user id is not valid in any other computer, try to store the IP in the user table, and check whether the call is from the same client. Cool | :cool:

thanks for your reply...

I have implemented using following steps.

1) i have create one more database table to store clientip and aspsessionid...

2) Create the function to store ASPSessionid and client ip to the table when user logged in successfully

3) Create the function called "validateUserSession()" to Validate sessionid and clientid

4) Whenever user requesting the authenticated page i am calling function "validateUserSession" with current sessionid and clientip

5) if the record exists in the table login success otherwise failed

is that correct approch..

Now problem is i am having nearly 80 to 100 parameters in each form and I feel it is cumbersome to add in each form that many no of parameters manualy.

Is there any function/routine to read the parameters from the properties and add it to the stored procedure and make a commad text?

Try passing it as xml and use OPENXML in SQL query to process that.
