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.

Record List Combo Box Problem

  • Record List Combo Box Problem

    I am a new user to Alpha V and was hoping for some advice. I have two tables created one for vendors and one for parts. These files have a one to one relationship based on the vendor_id field (auto increment). When creating a form I wanted to display a record list combo box from the related vendor_id field that was placed on the form. In the dropdown I did not want to see the vendor_id field only the vendor name. The problem is when I select the vendor by name, the name is placed in the related vendor_id field as well as the vendor name field. If I assign both fields in the dropdown all works as it should and the vendor id goes into the vendor_id field.
    Any help would be appreciated.

    Hi Keith, (good name, not many of us around)

    Welcome to Alpha.

    First question, you say you have made the two tables 1:1 relationship, does that mean a vendor only sells one part? Surely that should be 1:N (1:many)?

    I'm not sure what you are trying to do on your form. What is the purpose of the form? Is this a lookup you are trying to work with? Have you looked at the AlphaSports sample?

      Keith_B,

      Your description reminds me of "coded fields", a type of table lookup field rule. Follow Keith's advice and open the AlphaSports sample database. Open the Invoice Form. The grid in the lower third of the form displays records from the linked Invoice_items table. (In A5 desktop apps this control is called an embedded browse.) Notice that no product_id numbers are displayed. Instead you see only product "descriptions". Yet, if you examine the structure of the Invoice_items table there is no "Description" field. Just a field for the Product_id number. Alpha stores the product_id number in the table, but displays the "description" for the user. Is this what you're looking for?
