Dealing with win forms when breaking up the app

Hey All, Hows stuff

Right here goes, I've got my application so far and have decided to restart using more OOP methods.

I would like advice on the following

I was wondering, on how to break my app down into seperate installable modules, i.e. I have my main App which does certain things mostly handles data input & output.

however i would like to break this main app int chunks (modules) so when you install it your have the main app and then have to install seperate modules for those sections of the program to work,

Q1, would it be possible to have say 1 main app and 3 small apps example Human Resources module and when you click the menu item from the main up it loads hr.exe into the MDI child space
-IF SO
Q2, how would you open a certain form within the hr module.??

If any one can inform or advise me, how best to break the application up, into installable module, it would be great

Many Thanks

Carl

If you go the module route then I think it'd be best to use the same kind of structure as plugins. There have already been some great discussions on plugins if you want to search and decide to go that way. Note: other than knowing the type there is nothing much different about loading a form from a dll or an exe.
