Dynamically load ActiveX at runtime

[WojTec]

Hello. I have purchased AX control and I want to protect it before I deploy software to user. So, I want to load this AX dynamically at runtime without registering it in system (and will be the best without storage it as unprotected standalone file). I'm looking for native Delphi solution (or in other languages - I can try to translate it to Delphi, but this maybe to hard for me) for this task. Any help?

PS: I'm not interested in BoxedApp (or other "close" solution) - it's tooooo expensive for me.

An ActiveX control musst be registered in the system, because the system manages the objects therefore it has to know the AcitveX control. But where is the Problem? An ActiveX control is a compiled DLL. The only thing you can find out are the open interfaces, but you wont get the code. The only problem might be that administrative privileges are neccessary to register the control.

No, AX mustn't be register, can be load "virtually". Look at ThinApp or BoxedApp or other similar.

Take a look at that topic and at the sample code:

But you have to use LoadtypeLib or LoadTypeLibEx instead of LoadRegTypelib.

If u use ThinApp or BoxedApp have a loock into your temp folder and registry.
You will find your AxComponets in the temp folder and, registered in the registry.
ThinApp or BoxedApp isn't magic with ActiveX handling!

Also you might consider looking into manifests for side-by-side installation of ActiveX Libs.

Though it was intended as a possibility to run different versions of the same AX-Lib it can also be used to use AX without the need to register it.
Using manifests allows you to program as if the AX-Lib where installed on the client system. No need for special calls or routines. It just works. Note however, that WinXP or higher is needed.
