Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Is there any major restrictions on the number of users I can have in an AV5 Database, in MS Access I have been told you run into problems over 10 users.

      RE: Users

      Search the board using the "Search" feature here, and you'll find lots of people reporting 50 users and up. One well-published A5 database has 300 users. The primary limits you'll have are the hardware limits of your network.

        Well, not quite true. That's the maximum obtainable limits.

        Realistically, a poorly designed application can start slowing down with 2 users, but typically it's in the 10's of users before most see that.

        A reasonably designed application (network optimization, no operations that lock an application etc) can easily do 50.

        As you start to increase beyond that, good database practices (e.g. using temporary local tables, making sure LQO is invoked etc) come into play for designing an application to serve alot of users, but it doesn't have to be rocket science either.

              I'm not that experienced in Database design so I don't understand what you mean by "no operations that lock an application etc" and "using temporary local tables, making sure LQO is invoked etc".

              Regards

              Ken

                Ken,

                The question was whether alot of users could use A5 simultaneously. That's what I answered, a qualified yes.

                Go search the A5 manuals (pdf) and this message board using the keywords of my answer for more details about those other items. You should find most of the answers about what they are and what aspects you directly or indirectly can control.

                Regards,

                  LQO. Lightning Query Optimization? Temporary local table might be a table on a client that updates or is a clone of the "permanent" table on a server. It might also be a dummy table based on the server table but consisting of variables that are used to update the server table. I'm guessing the intent is to lessen traffic on the network and accesses of the table on the server. I'm not sure this is the correct jargon, but this may be a part of Ira's meaning.
