performance problem after porting .net 1.1 to 2.0

porting .net project to .net 2.0 cause lot of performance issues .

Server become down because of cpu usage, memory usage.

thanks

You are going to have to supply more details for anyone to be able to offer suggestions. Typically we see sites run much faster moving to 2.0.

hai

we have application which contains

1. client application

2. web application

These application use samewebservice which contains methods that returns datasets.
Dataset contains 7-8 tables (tables are merged in dataset using merge method)
Crystal reports arealso used.

In Web application ,expoted to pdf format

In Client application Crystal reports10 is used.

Aso session and view state is used .

porting .net project to .net 2.0 cause lot of performance issues .

Server become down because of cpu usage, memory usage.

thanks

permissions creating web application

The following error seems to plague a lot of people. Who has encountered this and what solutions did you find.

"Unable to create web project <name>. The UNC share <UNC> does not exist or you do not have access.

One suggestion I have seen a few times is create the app on the local machine and then publish to the server. I want to create the app on my develoment server, not on my local machine and then publish to a production box.

I noticed a post from one of this forums "ASP.net team" users stating something along the lines of "creating a web application is a snap just go to New Project --> .net web application". I laughed big time at that. I am in my fourth day of attempting this "snap" process.It works fine, but you have to make sure you have the correct privelages.. From the error it seems you don't have write permissions maybe?
yeah it is a permissions issue. The question is permissions for who? You have my local machine with VS.net installed. I log into a domain so I am assuming that the VS application is running with that account information.

I then try to create an application on a server outside a firewall and not part of the domain. That IIS server is running the show as far as the virtual directory and web application is concerned so I assume the account is IUSR_machine.

That to me seems to be a potential source of this problem.
Check if you have permissions on the directory you are trying to write to. I believe this is just directory permissions you are dealing with here.

Permissions Problem?

Hello All,
I can't seem to get my project to run in debug mode. When I run the web
application it says, "Error while trying to run project: Unable to start
debugging on the web server."
Any ideas?

I have already tried the iis restart, and have already reinstalled ASP and
checked that the server components were installed also. Still no joy.
Any other ideas?

This issue seems to be when I am running the IDE on the local machine (the

Persistent Forms Authentication - and Session Variables

Hi All!
I'm doing an ASP.NET project which uses Persistent Forms Authentication
(i.e. once user logged in, they don't have to log in again). However Session
variables are erased after Session has timed out. So I need to re-populate
user specific session variables (such as user email, DOB, Full Name...etc)
when Session has ended.
But strangely, when I tried to do something like...
Dim strArrayUserInfo(10) as String
strArrayUserInfo(0) = drDataReader("FName").ToString
strArrayUserInfo(1) = drDataReader("LName").ToString
strArrayUserInfo(2) = drDataReader("Email").ToString
Session("UserInfoArray") = strArrayUserInfo
I get System.StackOverflowException. If I comment out that line, application
runs correctly but fail at the point where Session("UserInfoArray") is
accessed (i.e. Null Exception). So I de-comment the above code and I was
thrown System.StackOverflowException again.
What could be the problem? I was merely assigning a variable to Session
variable collection. Why ASP.NET throws System.StackOverflowException'
Thank you all in advance!!!!

I bet you have something else called "Session". Change the line to refer to
HttpContext.Current.Session and see if that's any better.

Several ideas, none brilliant.
1) Simplify, simplify, simplify
1a) Instead of filling from the datareader, try setting the array elements
to constants. It's simpler.
1b) Try using Session("a"). It's simpler.
2) Are you setting all 10 elements of the array?
3) Turn Options Strict On.

Persistent Forms Authentication - and Session Variables

Hi All!

I'm doing an ASP.NET project which uses Persistent Forms Authentication
(i.e. once user logged in, they don't have to log in again). However Session
variables are erased after Session has timed out. So I need to re-populate
user specific session variables (such as user email, DOB, Full Name...etc)
when Session has ended.

But strangely, when I tried to do something like...

Dim strArrayUserInfo(10) as String

strArrayUserInfo(0) = drDataReader("FName").ToString
strArrayUserInfo(1) = drDataReader("LName").ToString
strArrayUserInfo(2) = drDataReader("Email").ToString

Session("UserInfoArray") = strArrayUserInfo

I get System.StackOverflowException. If I comment out that line, application
runs correctly but fail at the point where Session("UserInfoArray") is
accessed (i.e. Null Exception). So I de-comment the above code and I was
thrown System.StackOverflowException again.

What could be the problem? I was merely assigning a variable to Session
variable collection. Why ASP.NET throws System.StackOverflowException??

Thank you all in advance!!!!

Did you try using an array filled with constants? Did you try using
Session("a")? Have you turned Options Strict On?
