I am trying to understand multi threading. frmDetailProgress is a "please wait " kind of form. and i have a animated gif on it. Plus it has a check box to close automatically after completion. Well the form is frozen till the process is done. I am trying to get the piesthreadedtabletest to run in another thread. I have read allot on this but i just don't understand the concept. I don't understand the await function enough to make this work. i get that await is designed to stop processing until something happens. But i want that form freed up to work. I get an error saying that the function will run synchronously unless i have an await - Why?

Answer 1

I got it working. It was a lack of understanding and i probably still need to learn more. I hope this will help someone in the future.
i created a class to call functions in the other class running in the second thread.
imports system.threading
public sub callThreadedProcedure()
dim tp as system.threading.thread ' this will be for the object running in the other thread
dim objectToRun as myclass ' this is the object you want to run in the thread
'this gets the object and puts it into the new thread
tp = new thread(sub() objectToRun.FunctionToRun(<put your parameters here if any>))
' start execution of the object in a new thread.
tp.start()
' that will get it to run in a separate thread. It works, there might be a better way
' and might not work in all situations, but for now it fixed my problem.
end sub
if you are trying to run functions in the original thread you need to pass a
reference to that object to the one in the second thread. you must then use invoke to run a function or sub from the second thread.
Invoke(sub() obj.function(<parameters>))
thanks Idle_mind invoked worked like it should.
I appreciate all that helped me along.
