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.

  • One to one data binding in a UX

    I want to save two records to two linked tables in one UX component. Through data binding I bound the fields to their respective DBF tables in a one to one relationship through the builder. (the customer tbl & call tbl) I don t want them bound through a record number, I want to use the auto incremented field (generated via field rules) from the customer table and save it as a foreign key in the calls table: C_ID customer (auto incremented) = C_ID calls.

    Can this be accomplished by using an expression as opposed to using the record number in the builder? I linked the tables via the common C_Id field in the builder. both records are created but the value of C_Id saved to the calls table is zero.

    Can this all be just as effectively accomplished using the record number? I plan to exploit this relationship in other components (views).

    What am I missing? How can I accomplish this?

    I am guessing that the issue is being created because the auto incremented value is missing from the code saving the linked record. I know this value is available in the e.datasubmitted variable. Can this be captured in the expression, or would this have to be coded in an event? Or none of the above?

    Thanks

    I would have to conclude that writing to multiple tables within Alpha is not well supported to a dbf outside of a repeating section. I will try using a sql database instead, stay tuned.

      Re: One to one data binding in a UX

      Referential integrity is not that big of a deal for my app. I don t need cascading deletes, I just want to be able to add and link records in flexible ways. Data binding states that it allows you to write to one or more tables, but at least as far as DBf tables are concerned it doesn't let you link the tables via a common auto incremented primary, and foreign key, even though the binding builder allows you to link table fields. Unless I am doing something wrong?
