How to syncronize threads

[bdani82]

Hi!

I have a program with a FileSystemWatcher. Everytime a new file is created in my folder I create a new thread to read him.

Private Sub fSysWatcher_Changed(...) Handles oSysWatcher.Changed
oTh = New Thread(AddressOf ReadFile)
oTh.Name = e.Name
oTh.Start()
end sub

But I have a limit: if there are already 5 thread and a new file is created I want wait the end of one existing thread? How to di it?

Tks!

You can create a shared property that will count the number of threads you have running and test this property before creating a new one.

Ok. And if there are already 5 threads (shared property is 5) , how to wait the end of one of them before start the new thread? This is the problem.
