What is the purpose of a finally block in try-catch-
finally? I am confused because, if I am reading the
definition correctly, this block seems unnecessary.
Consider the following from the Visual Studio
documentation. In the first foo(), the statement in the
finally block will execute even though there is an
exception in the try block. In the second foo(), I took
the statement out of the finally block but it should still
execute since it...

Is it possible to have more than one try/catch/finally
block within a method? Also, if the code never enters the
try block of code, is the finally block executed? I have
a try block in a branch of a switch statement and I only
want the finally to execute if the branch of the switch
statement is executed.

Hi,
I was wondering what's the point of "finally" is in a try..catch..finally
block?
Isn't it the same to put the code that would be in the "finally" section
right after the try/catch block? (ie, forget the finally block and just end
the try/catch and put the code after the try/catch block).
Or does the "finally" construct add some additional functionality?

Hi,
regarding exception-handling :
why put code in a 'finally' block, and not just after a 'catch'-block -->
Example using 'finally ' :
try
{
OpenFile();

I was just pondering about what the Finally in an exception actually
does. Well, I realise that it always gets called regardless of whether
the exception is thrown or not, but isn't that the same as the next
lines of code? What's the difference between these two bits of code:
try
{
WriteFile();
}
catch

Variable scope doesn't make sense to me when it comes to Try Catch Finally.
Example: In order to close/dispose a db connection you have to dim the
connection outside of the Try Catch Finally block. But, I prefer to dim them
"on the fly" only if needed (save as much resources as possible). A little
further... I may wish to create a sqlcommand and datareader object ONLY if
certain conditions are met. But, if I want to clean these up in the...

I got caught with my pants down the other day when trying to explain
Try...Catch...Finally and things didn't work as I had assumed. Perhaps
someone can explain to me the purpose of Finally. I've looked at several
texts that I have and none of them address this specific point.
If I call some method that throws an exception in my routine Foo,
sub foo
call bar <- throws an exception
do something else <- never get here

Hello,
I've been looking in the archives but found no interesting answer to
my problem.
I was wondering why the following code does not work in IE 5; I'd
expect an alert showing 'In finally!', but I keep getting an IE error
dialog..
Has anyone any idea why that is so?
(the code works in mozilla :) )

Another wish of mine. I wish there was a way in the Try Catch structure
to say if there wasn't an error to do something. Like an else
statement. Try Catch Else Finally.
Also because I understand Finally runs whether an error was caught or
not, I haven't found a use for finally yet.

Howdy,
I ran into a very interesting issue and I'm curios as to how this is suppose
to work. I am using Try...Catch...Finally statements for all database
connectivity in my ASP.NET 2.0 web application. I'm connecting to IBM's
Universe 10.2 using UniObjects.Net. Anyway, if the connection errors, the
Finally closes the connection. What I see happening is that the function in
the Finally statement either isn't running or doesn't apply what...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
