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.

  • Set Structure

    What is the best way to determine a sets linking type in xbasic?

    I've tried Set.Structure_Get() with, what seems to be incorrect results. Perhaps I'll have to go deeper into the set's dictionary, but I don't know what to look for without experimenting.

    e.g.
    A standard 1:M set
    Set.Structure_Get("Cust_Del.set","T"
    always shows "Many Many"

    or
    A standard 1:1(first) set
    shows "Many First"

    Re: Set Structure

    Chris,

    On testing this it appears that the first item returned is always the top level table and is always designated as many even if anything below it is only linked by 1:1, not very helpful and maybe a bug. The "G" parameter is pretty helpful as this shows what is what. The following is based on Inventory set in alphasports
    Code:
    ? set.structure_get("inventory","t"+ crlf())
    = Many 
    First 
    
    
    
    
    ? set.structure_get("inventory","g"+ crlf())
    = (Many)PRODUCT
    (Many)PRODUCT.(First)VENDOR
    Nice AEX in the code archive the other day, thank-you

      Thanks Lance for replying & confirming.

      I've now managed to do what I want using the dictionary functions.

      Glad you liked the AEX and hope you find it useful. I've been resurrecting some old code I haven't touched for a long time in a v6 database. Most of the functions have been superceded by newer, better code. The functions in the archive were produced while learning xdialog.
