Questioncreating threads for parametrised methods Pin

I have a query related to multithreading.
I developed an application in 2005.
In this application i am calling some method in my code for every user
suppose for 50 users. but it will become slow if user increases.
so, i need to define threads which will handle task for particular number of users.
I have written the following code
'Delegate to parametrised method
delegate sub TaskMethod(byref o as object)
'In another method for particular users creating thread and calling method as
for i=0 to 10 'say 10 users and next will begin from 11 to another 10 like so
dim delobj as taskmethod= addressof Mymethod
'Implement mymethod
sub mymethod(byref o as object)
'task to do write here
end sub

problem i am facing is that all threads are using same resource( i mean connection to database here). so not executing properly. And i need to synchronised tthe threads.So defined the threadpool as
' replace delobj statement with
threadpool.<placing in="" queueevent="">(new waitcallback(addressof mymethod)

all other similar ways also tried but getting error in mymethod(as underlined by blue line)
i am stuck to it and not getting wheres the error lies.
So, anyone who knows please correct it and tell how to call a parametrised method inside some other method using synchronised threads.

Any help will be highly appreciated.
