>>I am testing a 3rd party DLL. When I use CREATEOBJECT() to instantiate an object this works but any subsequent attempt to access any of the objects methods or properties fails with message "0x8002801d - library is not registered". I then found on the web a solution to use CREATEOBJECTEX() instead and leave the second/third parameters as blank i.e. "". This now works properly. My question is can someone just explain what is going on here?
