I need to pass a delegate with a parameter to the thread manager, however, the threadmanager does not take a pure delegate and requires MicroFour.StrataFrame.Threading.ThreadManager.Delegate_ExecutionMethod which does not allow parameters. Is there anyway to get around this?





Public Delegate Sub GetData(ByVal passedInt As Integer)

Dim myMethod As MicroFour.StrataFrame.Threading.ThreadManager.Delegate_ExecutionMethod

myMethod = AddressOf GetDataSub



This obviously does not work since :



Method 'Public Sub GetDataSub(passedInt As Integer)' does not have the same signature as delegate 'Delegate Sub Delegate_ExecutionMethod()'

Sorry...messed that code up a little ignore the delegate totally. It's just a normal sub with an integer param

I didn't realize that the ThreadManager had its own delegates... thought it used ThreadStart and ParameterizedThreadStart, but looks like it doesn't...

So, since you can't pass a parameter, looks like your best bet is going to be to store off that value within a shared variable somewhere and then access it from the other thread.  Don't forget to use a SyncLock if you end up accessing that variable from more than one thread at the same time

What are the pros/cons of using threadmanager vs. backgroundworker? Been reading up on the bgw control and seems to do a lot of what the threadmanager does but allows passing an object through RunAsync and also seems to allow updating user interface controls. The downside I see is that if I want multiple bgw I need to drop several of these on my form where with threadmanager I can just add another thread through AddProcess. New to this world of multi-threading so forgive my ignorance...

This is a topic that we cover in depth in the training class.  There is a lot of detail that surrounds threading, events, and delegates.  As for your question, you basically understand it.  You would have to create a unique background worker thread for each threaded method that you wanted to call.  Using the ThreadManager, you can fire off as many threads as you need through a single control while managing the events associated with the ThreadManager in a thread-safe manner.
