hi friends,

This may be a childish question that i am asking but please help me out.
In symbian there are mainly 2 types of executables.

1) exe. (console based application)
2) dll.
They are again divided into:
a) static dll. (shared library [.lib] extension).
b) polymorphic dll. (.app,.fep etc).

Now here are my questions:
------------------------
1) In Symbian,s60 2nd edition sdk, all GUI applications have a (.app) extension , so can I say that every gui application in a second edition sdk is a polymorphic dll???

2) In Symbian,s60 3rd edition sdk, all GUI applications have a (.exe) extension , so what i want to know is that what is the type of gui application in s60 3rd edition????

eagerly waiting for your reply,
Thanks

Hi,

I think you are new to symbian. Ok let me clear your doubts.

1] In s60 2nd edition the applications had .app extensions ( .app and .exe are same ) but from 3rd editions the app is removed and all are exe.

2]you are confused about dll and exe i suggest you to go through them once.

Re: symbian binaries : exe and dll's

hi friends,

I got the info regarding my doubt.

1)
As of Symbian 9, since the privilege boundary is between processes, applications are .exe files that run in their own process,
whereas - in Symbian 8 and earlier - they were DLLs - .app extension - and loaded by apprun.exe.

2) In case of 3rd edition, GUI executables have no special attributes (though the 2nd UID usually remains to be 0x100039CE - I am not sure if it is mandatory or not). The code becomes a "GUI" one, if it invokes the EikStart::RunApplication method.

Thanks.
