VS2005 Exception Handling

[RG]

I understand how an exception handling occurs using try/catch when a single
statement or a block of statements are being executed. How do you handle
exceptions when you have managed code. For instance, you have databound
control and you need to catch a particular condition. How do you handle
that?

Thanks in advance

Your second and third sentences seem to contridict the first?

Try Catch Finally is a structured exception handling construct particular to
managed code. So i dont know what you mean by

How do you handle
exceptions when you have managed code. "

For instance, you have databound

control and you need to catch a particular condition.

It depends if by condition you mean event or exception? If the control
itself is throwing an undocumented exception then you have a bug on your
hands.
If it is throwing a documented exception then you wrap the method of the
control that might throw the exception in a try catch block specifically set
up to catch an exception of that type.

If by condition you meant event then you handle the event.

Thanks for your time and help.

I am talking about exception. Specifically, the framework was coming up
with exception when I would for instance use control incorrectly or have
datatype mismatch on databound controls. Considering that databound
controls are dropped into the application, how do you catch the exception?
as I am not writting a line of code.
In other words, I am not supplying that code. In fact, it appears that any
code that vb generates should left untouched as it would overlay the changes
on subsequent compiles.

Thanks again

In order to catch bubbled up exceptions lookup

AddHandler Application.ThreadException ...

Put that in your Sub Main... though I would wrap it in a
#IF DEBUG
conditional because during debugging it'll get in your way.
