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.

    Index help

    To All --

    I have developed an application with about 30 tables and 30 sets. Some of the tables have about 10 indexes, but one of them has accumulated about 35 indexes. Occasionally, I am experiencing problems that I think are related to these indexes. I have several questions:

    1. I understand that when a set is created by linking two tables together, Alpha creates an index. However, in control panel, when you choose a Set, Define Indexes, several other indexes also appear that were not created by the set. Where did these indexes come from? Are they all being used? How can you tell where they came from?

    2. Some of the indexes are duplicates caused by the use of parenthises in one definition but not the other. eg: (A=.t. .or. B=.t.) vs. ((A=.t.).or.(B=.t.)). If you alter the extra parenthises to make the first match the second and rebuild all indexes, the duplicate index usually goes away. What is being altered here? Will whatever created the index originally make it come back?

    3. If you delete the .cdx file for the table with 35 indexes, and click on rebuild all indexes, not all the indexes come back. Why not? If they previously were unnecessary, how can you know which ones to get rid of? Will they eventually come back?

    Thanks to all for any help you can provide.

    Possibly needed for lookups.

    3. If you delete the .cdx file for the table with 35 indexes, and click on rebuild all indexes, not all the indexes come back. Why not?
    If you delete the .cdx file, Alpha has no knowledge of what indexes you defined. The usual way to remove indexes is to choose Define indexes, delete one or as many as you want, then Build Indexes.
    There can be only one.

      Dick,

      In addition to Stan's comments, if you have a set based on three tables and each of those three tables have 10 indexes in them, your set will include all 30 indexes from the tables included in the set.

        Dick,

        Ignore my last response as it was INCORRECT. The only indexes that appear in the set are those defined in the parent table.
