It is good practice to handle exceptions as close to the source as possible. This gives you the opportunity to handle the exception in an intelligent way and resume work if appropriate. If you wait to catch it at the page or applicaiton level it may be too late.

Agreed. As with anything the trick is know when and how to use the tools you have. What I meant was not to just bubble the exception back up the call stack when it can be handled at the source, especially in the case of a class library. If I can recover from an exception in my library I don't want to make it the responsibility of the calling application.

Lets say if you accessing a webservice to retrieve party information and that causes an exception what is the most logical thing to do once it is caught? Im logging them at page and application level. Do I just revert the customer back to that same page where the error occurred and lot it or do I transfer the user back to the homepage and log it. Excuse my ignorance Im a novice with regard to error handling. Thank you

How you handle it depends on the application. Without know how your app is desinged to function I would say to return the user to the page with some message indicating what has happened, i.e "Invalid data", "No record found", etc. Give them a chance to correct any entries. If there is nothing for them to correct, then possibly it would be appropriate to return the to the home page.

With the try/catch exception handling you can provide 'alternate' solutions to any problem that you anticipate in advance... for example, if the db connection fails, or if the page dosn't load, etc. you can do something else for the user so that they don't see some error page or message... my 2-cents

instead of loading into an xmldoc ,
append it to a string and write it to response like
Response.Write(string)
you can handle the responsetext
as
responsetext[0]

What is this error and what should i do,pls help me? (I have VS.net 2003)
VS.Net has detected that the web server is running asp.net version 1.0.The web application you are creating or opening can be configured to be compliant with asp.net 1.0.
However, the application will not be able to use new features from asp.net 1.1.
|
|
|
|
|
You could install the .net framework 1.1...
The project you are opening must have been created under 1.1. For some reason you only have 1.0 on your machine. If you do have 1.1 installed, you may just need to register it with IIS.

Thank you for help.
I have installed the IIS server but i need to upgrade into 1.1 as u think so how can i upgrade .net framework 1.0 into version 1.1.
Thank you

Hi
Sometimes, I get the following problem:
I create WebForms in VS.net.
I drag & drop a button on the WebForm. Then I double click it to write the event code in the code-behind file.
Then I test the button event on localhost and it works.
Then I deploy the project on a Live shared server. I click on the same button, and nothing happens.
If I include the onclick= "Button1_Click" to the html code , then the button event works on both: localserver & live server.
So please tell me why I get this problem for some Button controls and how I get solve this problem ?
(As I said I dont get this problem all the time)

Hi there,
Are sure that the code in the local dev box is the same as that in the live server? You might want to double check the web page with the button that does not work properly.
From my experience, this phenomenon happens with the ASP.NET 1.x, are you using this version? So you may consider using your own code to wire up the event handlers in code-behind instead of using the generated code. Another option is to use the inline code to register the event handler like you have tried, and it's also used by default in the ASP.NET 2.0

Hi,
Is this a bug of ASP.NET 1.x? Because i too have faced the same problem sometime ago. But it got working once i removed the event handler code and again getting it by double clicking that.

I'm not sure if it is actually a bug as I didn't see Microsoft claims about it or I just miss that. But they said, you might have the postback event problem, when you run your ASP.NET on multiple load-balanced servers and the .Net framework 1.1 SP1 has not been installed on all servers. Also when I found that VS 2003 sometimes deletes the auto-generated code containing the event handler registration, I managed to put it on my own.

Probably because it is happening on quite rare occassions that hasn't got the much of attention.

how can i use timer control in asp .net page. my project is question bank management system. i need the question will move after few seconds. how can i set this. plz help me.
|

You have to use javascript, because asp.net can operate only on server side. Once server sends a generated page to a client, then it have no control over page behavior. Javascript function can cause postback after each few seconds or simply display another question.
