Please help me with this code - ASP.NET Discussion Boards

You need to add a catalog zone to your page. When switching the WebPartManager to catalog mode it will display and you can add any closed webparts back to the page.

There is no such thing as a webpartpagemenu control.

Do yourself a favor and do some research on the subject before trying to use it.

Does anyone know if I can use Ajax with VS2003 & ASP.Net 1.1 ?

Thanks

AJAX is a programming technique, not a tool. It is independent of VS and ASP.NET and has been around for years.

OK - I meant MS Atlas.

What line is causing the exception? Have tried stepping through it with a debugger? It should be evident what is causing the object null exception if you did.

Have tried stepping through it with a debugger? Roll eyes | :rolleyes:

You should see which object is causing the exception and be able to figured it. Roll eyes | :rolleyes:

Yes I have tried but still giving me that error message from that line.

To be honest I really don't understand what might be the problem

I'll give you a hint

Object reference not set to an instance of an object

Which object are trying to access that is NULL?

Sounds like you have NOT stepped through your code with a debugger. Do that before asking again.

I think they are referring to the objects that are inside the repeater because,I have used a repeater to hold my control,and I can use(capture from textbox,select from dropdown) all control inside my repeater(so when I click Add Entry buttton doesn't add my information inside my table,it gives me that error.

Hello,

I have a Web application running on ASP .NET 1.1 / Windows 2003 Server
with IIS 6.0.

We have been noticing our DefaultAppPool crashing occasionally. We
have installed the Debug Diagnostics Toolkit 1.0 and were logging the
IIS Processes. Last Sunday our IIS Crashed again (03/25/2007 7:23PM).

Appreciate your guidance,
Thanks

Srinu

If you look in the event viewer you should see the reason for the crash. Right click on My Computer then Management then go to the event viewer look in the application log. You should see an entry.

If you don't see an entry, then it might be that your application pool is recycling it self. By default it is set up to recycle every 27 hours or something weird like that. If you go to the properties of your app pool you can see what it is set at. I would suggest you don't recycle every so many minutes, but instead pick a time early in the morning 2am or something and recycle then.

Hope that helps.
Ben

Hello Ben,

Thanks for replying.

I could not find any info in event viewer regarding application pool crash.
As you said we are recycling at early hours (ie at 4am). And i dont think this might raise a issue.

But my client is unable to view the default page of the application i.e., whenever he connects to application he gets "Page not found error" and to solve this we use to restart the system. This issue come up 1-2 times a week.

Please reply regarding the same.

Srini

Srinu

So when you say your application pool crashes, it isn't actually stopped, but when you stop and restart the app pool it fixes your site? I would suggest you create a new application pool just for this web site. Just to make sure the problem isn't something else on the default app pool.

Hope that helps.
