List of what type of exceptions thrown? [Resolved]

Another general question. Is there a list of what type of exceptions can be thrown by controls, or do you have to look up individual methods? I.e., a list of all exceptions that can be thrown by combobox methods, another for ado connection objects, etc?

I don't believe there is a list but all Exceptions should inherit from the Exception object. The closest thing is to do a search in the ObjectBrowser. Pull up the ObjectBrowser from the View menu and click the search icon (it has a pair of binoculars on it). Then search for 'Exception' with the 'Match Substring' option and in 'Selected Components'. That should give you most exception types.

Thanks again. If I catch all the listed exceptions, do I still need a generic catch statement?

If you catch Exception then it will catch all since they all derive from Exception. You really only need to list other types if you want to handle them differently.

Yes, that's what I'm doing. Do I still need the generic in that case?

If you are using Exception then you are using the generic since Exception is the generic type.

Sorry, guess I'm not being clear.
Say I have:

VB Code:

Try
'...some code here, maybe opening a connection
catch ex as oledbexception
'...handling code
catch ex as invalidoperationexception
'...handling code
end try

and those are the only two exceptions listed in help for opening the connection, do I still need
catch ex as exception
after the first two.

Its not a must but it is always good to have a catch all.
