I want to migrate my application from VC++ 6.0 to MS Visual studio 2010.
I am thinking to compile my old code(VC++ 6.0) in Visual 2010 and resolve the compiler errors. Is it ok? Or I need to do any modification.

My application is having one exe and all other modules are dlls.

I believe that I need to compile exe as well as dlls in visual studio 2010.
Is it ok? Or I can only compile exe and dlls can be used as it is.
Because dlls are created in old VC++6.0.

Depends, you can't know until you've tried :)

Recompiling it all would probably be the most sensible option

If the dll's exposes a c api, and resource management, like memory management, is strictly encapsulated inside the dll's this may work. If that the case you probably spent some time on this during your initial desing.

Your best option is probably to recompile it all using Visual C++ 2010.
