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.

    Re: How many fields can one record have?

    Doug - thanks for pointing that out. At first when I saw your reply I was disappointed as it left me without an explanation as to what was wrong (I always want to know why!).

    So I started to review my tables again and sure enough, the problem wasn't the number of fields I had but the record size, which I was exceeding! Who would have guessed?

    I thank you for going above and beyond of just giving me the max field number - I would have never thought to look at that value. Now at least I know where to start "trimming the fat"! I could not believe when I compare my other records to see what size they were - all around 200-300, and my main patient table exceeding 16000! This explains a lot! Thanks again.

    In the help look under "Database Specifications" right at the beginning of the Users Guide.


    Fields per table record
    Records per table
    Bytes per record

    How many fields can one record have?

    I noticed some very strange stuff happening of late after I added yet some more fields to my main patient table. I knew I was around 300 fields for the past year and apparently if I exceed 350 fields I noticed any fields added after that were removed.

    Now I am not sure if the backup terminated these fields or alpha five table is the limiting factor - does anyone know?

    Because I did not know this, I was trying all kinds of things fix this - such as rolling back the database, reinstalling backups, etc. So the problem may with one of those actions.

    One of the resulting problems I can't for the life of me figure out is that some of the older fields won't save the data when a user enters it from the web. Fields I have not touched in a long long time and that is used by my end users every day. No matter what I do, I can't like 3-5 fields to save data but all the other fields will. Some of these fields have no calculations associated at all, so I don't believe it is that.

    Has any one experience any thing like this?

    I realize that not too many people would ever dream of using so many fields for a table that is used for a web site - I do think I have heard strange things can happen as I approach some limit. If there is such a limit then the tables should not allow you to enter new fields beyond that point.
