<font face='Verdana'><font color=navy>Hi all,

Info: DWMX - ASP VB

I am trying to build a site that requires a session control. I am new to sessions and I am trying to work out how to check if the session has been started.

My question is:

= ""

the same as

= Null

If I set my session variable to Null in order to reset it, does it make my variable = "" ?

Any advise most welcome.

Cheers,

Hi Barry,

This might not answer your question directly but I was also looking for the same thing... I came across a DW Extension created by Tom Muck (www.tom-muck.com) its called "remember me". Creates a cookie to validate the session with a check box to tick to remember the cookie values. Hope it helps... here is the source of the extension. As to your question if Null and "" is the same? Well he has used "" without any representation of the Null statement.

&lt;%
If cstr(Request.Form("textfield")&lt;&gt;"" Then
If Request.form("checkbox" ="1" Then
Response.Cookies("myusername" = Request.Form("textfield"
Response.Cookies("mypassword" = Request.Form("textfield2"
Response.Cookies("rememberme" = "1"
Response.Cookies("myusername".expires = Date + 60
Response.Cookies("mypassword".expires = Date + 60
Response.Cookies("rememberme".expires = Date + 60
Else
<b>Response.Cookies("rememberme" = ""</b>
Response.Cookies("myusername" = ""
Response.Cookies("mypassword" = ""
End If
End If
%&gt;

Hi Barry

Just to add to Allan's comments, NULL and "" are not the same.

"" is a zero length string

NULL is an unknown value
