I've heard a lot of talk on the forum about memory managment in .NET and
disposing things, finalizing them, garbage collection, etc. My question is
which managed types need to be disposed after being used, and for which is
it OK to simply let the garbage collector do its work, without worrying
about calling Dispose? Is there a general rule that most don't need to be
explicitly disposed, with an exception here and there? Or the other way...

If anyone can figure out how to implement the following C++ function in C#
using interop, I'd be very appreciative.
I have not been successful in getting it to work correctly using interop
(without using unsafe code) because of the pointer issues of the structure.
Thanks,
Chris

Hello,
I have question regarding disposing objects in aspx/cs pages. If I create
some objects/Arrays/ListArrays in pageLoad do I have to dispose them (by
assigning the null value for objects that doesn't have dispose method). If
so then where should I do this? I need to use those objects in scripts in
aspx page (they are created in cs PageLoad) - so I have to dispose them
after they are not needed any more.
Cheers

I am trying to take a working VB.NET program (the SHOW HTML program
from the Halvorson book) and pass in parameter values which are used to
build the URL that IE looks up.
The original program works with a fixed URL, such as
"http://www.microsoft.com". Interop.SHDocVw is part of the original
program.
However, when I bring in values from outside the program, the url
string is built correctly, but the program crashes saying:

I'm rather confused as to whether something should be disposed of, or not.
What is the general rule? How can you be sure of doing the right thing? I've
heard about disposing unmanaged resources but what is an unmanaged resource?
Does everything need disposing?
I've been using Webrequest, Webresponse, Streamreaders etc. How can I be
sure of what needs disposing?
Do these get automatically get disposed of at the end of the procedure...

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.

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...
