Rob, <<Aren't there already software packages that do that? I think Red Prairie has something like that. Are you writing this for J.C. Penney? JCP is already an RP customer.>> Yes, we are, I do believe, a partner of "Rouge de la Prairie." I will czech out their site to see what they have; yet, I find it hard to believe there would be something available "off the shelf" that will do the trick. <<Several times per second? Why? What are the consequences if notification that a package has arrived is delayed by a fraction of a second? What are the consequences if it's delayed by even 30 seconds? Is someone really going to be watching the screen that closely? I can only see an issue if the operator is standing there watching the package be delivered, or if the operator is on the phone with the delivery driver who reports that the package is in place. Either way, the operator no longer needs the Web page to report delivery anyway.>> What's going on here is an operator first starts a Batch, or Distribution, by scanning a barcode. This updates a label to say, for instance, "0 of 50" (0 of 50 items have been inducted). As a message comes back from the RealTime that the first item was seen (by the photo eye), this needs to change to "1 of 50", etc. The operator keeps an eye on this, because once it becomes "50 of 50" he/she will be looking for a label to scan to begin the next Batch/Distribution. They ARE used to seeing their display updated in "real-time", and this system we are creating is a replacement for the existing one. They will moan like hound dogs if the new system seemingly has LESS functionality than the tried and apparently not-so-true. <<How complicated are the queries? Will your database server be able to handle 150 of them per second (figuring 3 queries times 50 operators)?>> Not very; in many cases it would just be looking up the value for a display element, zB "Select Number_Inducted FROM MainFormDisply" or some such. <<Couldn't the real-time app write to the database itself?>> That was my idea, but The Powers That Be/The Deciders say they don't want to do it that way. Sometimes it seems to me they are intent on doing things as indirectly and unintuitively as possible.
