DLL vs Units

[kristof]

Hi all,

When should I use a DLL instead of additional units?

I'm a bit reluctant to use a DLL because getting it registered on the client computers seems tough.

Any tips about this?

Gtz,

I personally keep my units until i am very sure the functions in them are running perfectly. This is very helpful for debugging. When my program appears complete, I convert my units to DLL's. When many users are using your software, it is much easier to send them an updated DLL than to recompile the program (using the units). As long as the function headers remain the same, you need only replace the DLL file. Another advantage of a DLL, other developement tools, example C++, can access those function in the DLL's.

On the flip side of the argument, if you want to distribute less files with your applications you may want to stick to units as these will be compiled into you .EXE

So choose what is best for you less files or upgradability and reusability
