session variables in vbscript

[blexman]

I am comparing session variables to null. I am getting different results dependending on how I code the if statement below :
<%....

if isempty(session(&quot;x&quot) then ... ;this seems to work INcorrectly if x is null

if isempty(response.write(session(&quot;x&quot)) then ... ;this works correctly if x is null

or what about

if session(&quot;x&quot=nothing then ...

or

if session(&quot;x&quot=&quot;&quot; ...

%>

Any suggestions on how to check for null strings in session variables.

thanks

Try changing this

if isempty(session(&quot;x&quot) then

To this

if isNull(Session(&quot;x&quot) or Session(&quot;x&quot = &quot;&quot; Then

This should do it for you

I usually use if session(&quot;x&quot=&quot;&quot; because it can only be null if you expressly set it to null - which I never do. If the variable has never been set, it will return an empty string (&quot;&quot Get the Best Answers! faq333-2924

the isNull works....for whatever reason &quot;&quot; does not work.
