Question about thread safety...

I have a question about thread safety in a VB application written using Visual
Studio.Net 2003.

Here is the situation...

I am running a process thread in a modal dialog. I have written it so the user
cannot exit the dialog until the thread completes (unless they click a button
to explicitly interrupt and destroy the thread).

My question...

How concerned should I be about accessing the dialog's member variables from
within the process thread? These are variables that cannot themselves be
changed anywhere on the dialog window.

Thanks,

Dennis

You really need to try a dotnet group, this is for classic
VB.

Sorry, I guess I don't understand the difference (since this is a VB
application - emphasis on application).

Can you give me the full newsgroup name where I should post? I did a search
for newsgroups containing "dot" on my ISP and did not find any microsoft
newsgroups. Maybe my ISP is missing these groups.

Thanks,

Dennis

Yes but MS took the name 'VB' and applied it to a new language that has
little in common with what was called 'VB' before. They created new
'dotnet.vb' newsgroups for the new language while the existing newsgroups
were left to continue providing peer support for vb 'classic'. Blame MS for
creating a world of confusion by not giving their new language a new name.

try the new server msnews.microsoft.com

<response type="generic" language="VB.Net">
This newsgroup is for users of Visual Basic version 6.0
and earlier and not the misleadingly named VB.Net
or VB 200x. Solutions, and often even the questions,
for one platform will be meaningless in the other.
When VB.Net was released Microsoft created new newsgroups
devoted to the new platform so that neither group of
developers need wade through the clutter of unrelated
topics. Look for newsgroups with the words "dotnet" or
"vsnet" in their name. For the msnews.microsoft.com news
server try these:

microsoft.public.dotnet.general
microsoft.public.dotnet.languages.vb

I will check with my ISP and see if they can get these. If not I will try
msnews.

When did you last refresh your newsgroup list? You may have
them already, if not the msnews servers works just fine.

I refresh weekly. I am waiting for a reply from my ISP to see if they can pick
up these additional microsoft newsgroups. If that fails I will try msnews.

Thanks,

If all else fails, there's always the web based group browser....

I'd try msnews first and the ISP only as a last resort. If you can connect
directly to the msnews servers why wait for whatever propagation delays are
introduced by going through the ISP?

The only time I've used ISP-based servers is when the ISP blocked direct
connection attempts and they certainly weren't my ISP for long.

If you are using Outlook Express, then go to Tools|Accounts|News|Add, and
then add the server. Or just click on the following

news://msnews.microsoft.com
