I don't see what the problem is.
Is it that the session expired early? Did you not get a session at all? Is it something else?

I'm going to hazard a guess that powerpoint is not installed on the server.
|

Hi Paddy,
Thank you for your response.
I just checked on the Server, but PowerPoint 2007 is installed there.
Looks like something related to permissions, but I am not sure what the solution is.

Hi all.
We have an asp.net web email app. Intermittently when a user logs in, it shows the inbox for another user. After you refresh or login and logout, it show the correct inbox.
Has anyone ever experienced something like this? What could possibly be the cause? Went through the code, etc and everything seems fine. Perhaps the server setup?
Any help would be greatly appreciated.
Thanks
M

I think it can be cause of Session Variable, May be previous user session didn't clear properly .

Yes I get you, we ruled this out as a possibility though.
It's a mystery to us

You haven't told us what login mechanism you are using.

Few companies that installed computers to reduce the employment of clerks have realized their expectations.... They now need more and more expensive clerks even though they call them "Developers" or "Programmers."

Just one suggestion Raj kumar, If this is your final/ production code, Please be aware of SQL Injection
BTW : "Re: dont be smart Vuyiswa Maseko" what was the reason to write this subject and why did you change that ?.

Don't be rude. If this is your attitude, I am sure you are not going to get any replies.
Good luck!

This can be done by WebConfigurationManager Class . WAT also using the same class for its operation .
Here[^] is some example. I believe you can now go ahead !!
