typically I only use exceptions for rare happened errors.
Althrough MS said using exceptions would not bring too much performance penalty,
I doubt it. Java will have performance penalty when using exceptions especially
for JIT VMs. You can find infromation from IBM.
If the error is really a "wrong opertions", just use exceptions for good code
management. But don't abuse exceptions. I have seen some guy used exceptions
for the situation that would happen > 20% probability. That's really not

Do you plan what exceptions and how many exceptions
before you start coding?
Thx.

depends on how many function models you have.
I like to classify exceptions from their models.
And I always give a way that when end-user administrator
reports us the error message, we can find the exact palce
of that code.
I also wrote exceptions manual in my formal company. :)

1) MSDN 上有个关于EXCEPTION MANAGEMENT的APPLICATION BLOCK
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnbda/html/emab-rm.asp
2) Also, an old but good guide on EXP MGMT
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnbda/html/exceptdotnet.asp
3) A list of references :
http://www.dotnet247.com/247reference/guide/39.aspx
4) 这本书的第二章,有一段对于EXCEPTION,TRACING,LOGGING比较精辟的论述:
碰巧,AW上的SAMPLE CHAPTER就是这一章.
