Multithreaded App to send admin messages

Basically i need a multithreaded app using ([login to view URL]) thread factory if u need a good one.. with flexible number of threads (using a slider or something) to message all admin on network of a class "B" ex.. 192.168.x.x (from [login to view URL] to [login to view URL]) .. message is on a form as well as ip range.. a start stop and reset button is needed... I need to message all admins on our network of upcoming router changes or downtime schedules.. etc.. the [login to view URL] library ocx has already a progress demo app witch does it all (almost) ..just need to use net send to send message. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform xp , 2000 , nt
