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.

  • ISBN Fields

    I'm writing a database that is basically a library operation. I was just wondering how you that have done this are handling the ISBN field? Or are you breaking it up into the 4 specific fields? Are you hyphenating within the field?

    I looked in the forum 'search' and found nothing except one with no response. I may also need to poll a website to lookup and ISBN and return title, author, etc.

    Interesting project---!

    RE: ISBN Fields

    If you need to search or index on parts of the ISBN, it would be better to store the parts in separate fields and concatenate them when the full ISBN is needed in reports, forms, labels, etc. If you never need the parts of the ISBN individually, then store it in a single field. In general, it's easier to store parts and put them together when needed than it is to store a large string and take it apart when the parts are needed.

      You could set a mask in the field rules so that the operator does not neet to deal with the dashes.

        I would do that but sorting might be a problem since it would then no longer be a numeric field.

          Don't use a numeric field unless you're going to do arithmetic operations on the data. Use a character field. If you need to sort numerically, you can use the expression val(character field).

            RE: ISBN Fields

            I'm thinking you might be right--except that a string like 1-254-2343-1 when taken with the val function will not return the complete numeric value of 125423431 I don't think. I could always break the number into 1 254 2343 1 in four seprate fields (which is the ISBN format) and then sort (if I wanted) by the second field then use the str$ function to create 125423431 from str(1)+str(254)+str(2343)+str(1). I'd be tending toward this method at this point but I can see your suggestion too. I might be waxing a bit philosophical here. If ISBN had even one alphanumeric character in its string--that'd cinch it. But all numeric I'm tempted to go with numeric fields. I wonder what the big boys and girls do?

              RE: ISBN Fields

              I see your problem. In general, use numeric fields only when you have to do a numerical operation. The difficulty is in numeric fields:

              123+456=579

              In character fields:

              123+456=123456

              And it's always possible I don't fully understand the problem and I know I don't understand the ISBN system.

                Well, I found another reason. ISBN fields last number is a check sum. So I do have to do calculations if I want to do that. Thanks everybody for your time.
