C# Automation

Howdy, I need a simple C# alternative to using VB COM objects, i presume they would be done using interop, but I leave that to you. The aim is to have a excel .xla addin call c# and do the following tricks from XLA Addin using c#: - Run a windows form made in c# in modal mode - Pass worksheet to c# and manipulate/automate it there and return control. - I will require a demo with a [login to view URL] dataset retrieved into Excel via a call to c# with paramters from excel (select * from ". It must be possible todo automation/manipulation similar to that of VBA on active worksheet passed to code (look at at <[login to view URL]>) .. for help on making the automation server, you can lookup here: <[login to view URL]> but i cant get it to work in MSVC. Demo should be a xla macro that is run modally and pass active sheet to c# for manipulation and passes usercontrol back when done as if it was a normal VBA macro being run. Secondary sample should pass some form of paramter to c#. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.

Process _MUST_ be started from excel and not from C# similar to that of VBA using COM objects.
