A Dll like application shared between multiple processes?
Posted on 1998-09-18
I have a problem which you might be able to help me with.
I have an NT server that is attached to about 20 printers.
I am printing hundreds of jobs to these printers in a short
amount of time.(Bitmaps). I am having problems when something goes wrong with the printers. If something
happens to one of the printers, the queue gets backed up
with hundreds of jobs before the user notices that
something is wrong. I know printer pools, thats kinda what
I want to do. I can't use printer pools because I have to
know what job goes to which printer. I am trying to
program my own printer pool. Here is where you can help.
I have devised a .dll that my application uses that
has a "Black box" set of interface instructions. Submit Job
Get printers average number of jobs etc.....
I want to have this dll running on the server and be able to
have applications call the submit job function with a handle
to a bitmap and have the print server print the job.
I need to be able to have multiple processes attached to the
same server because I have 3 different front ends for the
jobs that need to run simultaneously on the server and over
the nt network. Can this be done? I know that it cant
be a .dll, but maybe there is some other method of
programming a com? or something like that that has this functionality?.. Please help
