How to modify only one form in an application having many forms

Posted on 2004-10-20

I have developed an MDI application that now consists of nearly 30 forms. When any of the forms has a bug, I need to fix and recompile and then save the exe to shared application path. But very often it is not easily to disconnect all the users whenever I want the changes to immediately released. What is the best way in application development to modify only one interface and update the changes while other interfaces are running from the main application?

I think you can do this only if you application is organized in different modules (Exe DLL or OCX)
if you compile your modules with binary compatibility option you can recompile only one module without changing the others

Obviously you can't change a module while a user still using it (but you can change modules that aren't used at the moment)

How do you make the application binary compatible? Within an application how it is intergrated as units so that one can modify the desired dll or ocx and later transfer the changes to users.

You can read here about binary compatibility

you can set it from the project properties/Component panel (only for ActiveX projects)
