I am pondering a large application with different modules and several hundred screens, etc.
My question is:  How do I develop this large of an application?  Do I create multiple .exe's and a calling form?  I'm looking for how to develop large application and manage the project in the project window with multiple programmers, etc.

Hi Joey,

As you've nominated this as an easy question I assume you're after a fairly high level answer.  I would say that the best to develop a large application like you are describing is by using the same structure that Microsoft use.  If you look at any MS application they usually have a single .EXE file which is very small and is basically just an entry point and then a whole series of .DLLs which contain the serious code.

The beauty of this is that if that each logical component can be designed, implemented and tested separately (by different people) as long as the design of the overall app has been done.

Of course this means that there actually has to be an overall design of what components are required and how they should relate.  This should include a detailed description of the functions that each .DLL will export etc.

As to further management of people and code this a significant issue but basically comes down to your management strategy (i.e. its a WetWare issue not a SoftWare issue).  There are tools to help, however, like MS SourceSafe and other version and code management systems.

Hope this helps,

James
