Can I the customer, control the loading or unloading of COM Components?

We do not allow such control in a shared hosting environment. Our support team loads and registers all COM components on behalf of the customer. The requirement you seek is more on the lines of a dedicated server and not shared hosting. Our process is as follows:

You create a folder called "DLLNew" or the days date and FTP the DLL's in the directory.

Send en email to stating the location of the DLL's and any other instructions.

We receive and process it. 

There is a $2 registration fee for each COM/DLL registered.
