Critical Sections of code

[Sid Price]

I have a multi-threaded VB.NET application and I need to be able to access a
shared set of variables from multiple threads. In CE.NET there are objects
called critical section objects that a thread can acquire on entry to a
section manipulating such variables and release when done. Any other thread
trying to acquire the same object will suspend until the object is released.

Is there such a mechanism in VB.NET please?

Thanks,
Sid.

Its a bit difficult to describe it all here, but yes it does. Look up the
"Synclock" keyword on the net.

In addition to Ken's information you may find the Mutex useful.

Check out the 'SyncLock' statement and the .NET Framework's 'Monitor' class.
