Actually, there are 256 bits in a byte.... <grin>, ya learn something new everyday, I know. <grin> It does come from that, in a way. The very first bit is used to determine if it's exclusively locked, then the rest of the bits in the byte are used to determine if a user is 'active'. It's in the header of the .mdb.

This does not discuss performance, only possibilities. I can store 255 automobiles in my house... As long as I tear out all the walls, crush the autos flat, and stuff the house full of crushed autos. But all I'm telling you is that I can store 255 autos in my house. Absolutely true but not terribly helpful. It also says you can have a maximum of 4 billion records. Of course the container won't hold that many, but if it would, then the other structures that organize the records are based on a long int so they can only hold 4 billion possible values. John W.

But I'm equally certain that those connections can't be a) all to the same table, b) pulling back very much data, or c) held over a WAN. The problem is that MS blithely throws out that 255 concurrent connections figure without providing any context. And now there's a legal battle brewing. Forgive me for losing track of the thread, but which of us is having this legal problem? I can't find the original message. -Christopher- ---------------------------------------- From: "John Bartow" <john at winhaven.net> Sent: Monday, January 24, 2005 12:33 PM To: "'Access Developers discussion and problem solving'" <accessd at databaseadvisors.com> Subject: RE: [AccessD] Time for More Legal Discussion - Oh Boy No, M$ tested it with little bird poopey uses connected concurrently and they could only get up to 127 users. They used flea poopey to get 255. :o) John B. -----Original Message----- From: accessd-bounces at databaseadvisors.com [mailto:accessd-bounces at databaseadvisors.com] On Behalf Of Nicholson, Karen Sent: Monday, January 24, 2005 12:26 PM To: Access Developers discussion and problem solving Subject: RE: [AccessD] Time for More Legal Discussion - Oh Boy Yeah, but the guy paid over $10,000 for the system. He wants that back. What can you do when Microsoft claims that Access can handle 255 concurrent database connections at one time? We all know that is just bird-poopey. -----Original Message----- From: accessd-bounces at databaseadvisors.com [mailto:accessd-bounces at databaseadvisors.com] On Behalf Of Brett Barabash Sent: Monday, January 24, 2005 1:13 PM To: Access Developers discussion and problem solving Subject: RE: [AccessD] Time for More Legal Discussion - Oh Boy Karen, First of all, if the total loss is $3000, this is clearly a small claims court issue. A civil court won't hear a case under $5K, and it wouldn't be worth it for the client to pay a lawyer to recover such a small amount. Of course, explaining dumbing down the evidence for a small claims court is no small task. Secondly, there is the legal concept of mitigation of loss. The client will be burdened with the task of proving that they didn't know about the bug six months ago. If it can be proven that they did know about it and said nothing, the actual amount of damage will be greatly reduced. And finally, if this can be proven to be a Microsoft technology issue (security flaw, data corruption bug, etc.), and it is documented (knowledgebase, 3rd party journals, etc.), it should be easy for the developer to prove that they were not at fault. I have gone down this exact road with a MS solution provider for way more than $3000. After we reviewed the facts, it was clear to us that the problem was with the product, not the consultant. So sue Bill instead (oh, and good luck with all that!). -----Original Message----- From: accessd-bounces at databaseadvisors.com [mailto:accessd-bounces at databaseadvisors.com] On Behalf Of Nicholson, Karen Sent: Monday, January 24, 2005 11:13 AM To: accessd at databaseadvisors.com Subject: [AccessD] Time for More Legal Discussion - Oh Boy What happens when a program is written for a customer using Microsoft Technology, and the Microsoft Technology is bad - its data, its logic. It has cost this one client, he claims, $3000 in lost revenue and he wants the payment for the system refunded plus damages. The user never notified said programmer that there was a problem even though they have been using it for a good six months. ------------------------------------------------------------------------ -------------------------------------------- The information in this email may contain confidential information that is legally privileged.
