debug compiled code
Hi,
I run an online app using classes in a dll that i wrote to execute business logic and data access. The thing is, whenever there is an error in the code inside the dll, it only shows the error on the line in my aspx that calls the method in the dll. Is there an easier way to debug, and get the specific error out of the compiled dll? I realize the original code isn't actually inside the dll, but I'm wondering if any of you experts have a better method of debugging?
Thanks,
Trevor

how are you handling the errors? try/catch code please (especially the catch part) :-)

I'm not handling the errors.. there shouldn't be errors in the code that i'm writing, but of course WHILE i'm writing it, I make mistakes and need to debug...
I take from your post that you arent using Visual Studio or some other IDE that allows you interactive debugging?
As raterus suggests you could use try/catch code (you probably should have error-handling code in there anyway).
You could also enable tracing within the application to assist you.

maybe i need to start using visual studio.. i'll use this as another reason to do so, and maybe i'll be able to convince my boss :)
as far as try catch goes, i do things like float.Parse(mySqlParamter.

how do you throw an error up to the application level?
Here is a MS link with example code about throwing exceptions
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconthrowingexceptions.asp
If you dont have error handling then the error will automatically filter up to the next level. If there isnt eny error handling to catch the error then the error is thrown to the browser.
