I have a C# application and a VB6 application that need to share a dialup
connection to the internet. Don't ask why, this is one of those corporate "do
or die" things.
The only way I can see to do this is by using the combination of a MUTEX to
create a Cross-application Singleton for the Dialing operation and a Named
Semphore that can keep a count of how many processes are currently sharing
the connection from the client's workstation into our corporate VPN extranet.
I am trying to find an example of how to manage semaphores in C# in a class.
I will have to translate the same into the VB6 for the legacy app.
Using .NET 2.0 is not an option, they won't let me use a BETA. Neither is
remoting. I have to make the access sharable between executables modules.
Does any one have any ideas.

Again, I don't think any one understands that these are 2 spearate
executables. Monitor won't do it. It has to be something similar to MUTEX but
will allow a certain number of executables to share the Connection to the
internet and will prevent which ever one completes first from hanging up on
the second one. The MUTEX would only prevent one from dialing while the other
one is dialing. The Semaphore tracks how many active transfers are going on
simultaneously.
Please any more ideas.

A week ago, I posted a sample implementation of semaphore using Win32 API.
This solution can be adjusted so the semaphore handle can be shared among
processes, which will suit your needs, if I understand what you need to
accomplish.
This is were the implementation is posted http://www.pcreview.co.uk/forums/pri....php?t=2099193
have a look at MSDN for settings you need to change when handle should be
shared among processes.

I guess you should consider me dumb as dirt, because I can't see how I can
implement this in such a way that all processes will have access to the same
named semaphore when the only constructor that implements the name is
protected in your example. I am not being factious, I just don't understand.
Most of this is brand new to me and I seem to keep getting thrown the
projects that would even give MSDN MVP's pause for thought.
Would you please explain this a little further, Lebesgue, so that even a
clod like me could understand.
Thanks.

Semaphores in Perl are provided by the (obsolete?) "Thread" module, which has been replaced by the "threads" module in recent versions. But in the latter, there are only locks, no...
