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.

    UX Dialog databinding with multiple unrelated tables or one-to-many with link tables

    This has thrown me on a loop:

    1. I have a mobile UX control with multiple panels that manipulate data in multiple different tables (same database.) When I go to create data bindings, the ONLY thing AA lets me do with multiple tables is hierarchical parent-child relations. I don't want relations between many of the tables, as a matter of fact I can't have relations set up between them because they are not related! Do I give up on data binding and do this kind of scenario manually through XBasic?

    2. What about many-to-many relations with a link table? For example:

    Actions can have many items, and items can have many actions. So the schema looks like this:

    Again, do I just handle this in code?

    I think you can do it in a dialog
    make all the controls you need from the two tables in the dialog, action and item.
    but on the data binding add all the three tables with proper linking.
    then you should be able to bind them
    and add the data as needed , I would imagine.

    many to many, probably no., or I do not know.

      Re: UX Dialog databinding with multiple unrelated tables or one-to-many with link tables

      Given that AA doesn't allow me to create data bindings for unrelated tables for some odd reason (and I'm sure there is a reason behind it, odd or not,) I can't do what I want to do using data bindings. I decided to bind just the Action -table. I couldn't even add bindings from the Action to the Action_Item -link table, because it needs to be 1-many, and alpha data binding croaks big time on that unless I have repeating sections in my UX. Which I don't, since I use the highly recommended list control. As a result, I'm having to hand-code almost all of the data action in XBasic (ugh...) Doable, yes, but not fun nor convenient... As for many-to-many -- might as well forget about trying to get something like that done with AA's data binding. <sigh>
