I just seperated my class components into their own activeX dll files, Thinking that i could update the DLL and not have to update the program for updates. But when i recompile the activex Dll and put it in the directory with the program it gives me an error "429 - ActiveX component can't create object". What do i have to do so that i can update the DLL without having to update my program code.
Never mind, I fixed it, I found out that i had to set binary compatability.
Hi, there is a tutorial in this web called The COM course Part3. It explain to you how to solve this problem. In this moment, i can tell you that the problem is the way of compiled the Active X DLL.
See you.......

if ur making a DLL for the First time.. u can set it to no compatibility or project compatibility.. but the next time u make DLL again (after changing the code in dll) .. u hav to set the option to Binary compatibility...
You can change a dll after distributing it.
If it was compiled with binary compatibility on you can use the changed dll in the old program without any problems , this is if you take some notes in mind.
The used functions subs may not be removed and the parameters may not change of them. You can change all of the code in the scope of the function , you can add parameters but then you have to put optional before the added params .
This you can do with binary compatible on a dll.
