Making DLL's

Can you create dlls in B3D?

I'm afraid not :o) You can create them in purebasic though.

purebasic? is there a website for it I could check out?

First item on the search list.

Are there any other programs (besides C++)

Well, C++ isn't a program.... But you can make DLLs in tons
of languages...

Like:
C
C#
C++
BlitzMax (With this MakeDLL thingie by someone I forget :/)
And more!

Delphi can aswell
D can probably do it too

Pure Basic would be the easiest of all of them for making .dll's.

I meant C++ as in a language. sorry for the misunderstanding.
