Look at TJVPlugin for dynamic packages

I am just learning it myself but it looks very powerful. It makes the dynamic loading/unloading of packages just like what you're looking for quite easy and intuitive. To obtain the full benefit you will have to use runtime packages in all modules. This can be tricky if you have a lot of 3rd party packages in your code. I still like it though; I think modularized programming is the way to go.

I forgot to mention: TJVPlugin is part of the Jedi component packages. I don't have the URL handy but a google search should get you there pretty quick.

I am currently looking into the TJVPlugin components documentation …
I did manage to figure out the problem I had …which was when I load the form the package it would give an error about coinitialize not called.

The fix was to include the Activex unit and do co Initialize () before the function I used to create the form and couninitialize after the function.

I have gotton over the initial problems of calling the form from both a dll and a package
No I am just trying to figure the quirkes as I go along… paclages will load MDIchild forms dll will not. Well as far as I know anyway..

That’s tip should provent you from going thought what I had to…
