No when I say remote Microsoft in it's "wisdom" presumes that the file you
have open in the computer screen in front of you is the one you wish to be
the design master or in fact is a design master you wish to make a replica.
Very good for the programmer but not very good for a user who has to
actually do the work. So if you create a tool that is a database application
program with a more suitable UI designed to pragmatically create a replica
or a design master of a datafile that is another computer file not yet
opened - i.e. using a connection to actually manipulate the database not
using the database itself and it's UI, it seems that things get messy.
Now this is fine until you find that the DLL versions on the users computer
is not the current version used in the development environment OR that they
are using a latter version of the required DLL. NOW we have DLL hell, do you
replace their version or not? Is it the DLL that is the problem or not? I'm
sure you have encountered this issue? The net result is I am finding it hard
to get past first base and actually provide an application database that has
code that will allow a user to create a design master successfully without
actually using Microsoft's UI. Now considering that I have to cater for up
to dozens of independent users/purchasers of the solution who have trouble
even copying a computer file from one computer to another and they need to
able to at least synchronise their table file, it is fast becoming a
nightmare compliments of Microsoft. Forget the wire, this is on their own
computer, never mind internet or network synchronisation (won't even go
there). In any case it seems I have a "too hard" and I think that for the
first time I shall say die and give a miss. Replication appears to be a
"programer/administrator managed only" solution.
