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.

    General webDB design question(s)

    I built a number of tables with fields that were auto-calculated depending on values looked up in other tables. Everything was going great up until I began testing my ability to update the underlying values and it looks like my field rules are looking at my original tables instead of the web ones.

    I've used the ADB path alias, but it doesn't seem to work in the field rules (maybe I typed it in wrong, but lookups were still occuring so I don't think so). Is this just a limitation? Will I need to hardcode the webpath in the lookups? Or am I best off just handling all the rules in my project and leaving the tables uncontrolled?

    Any advice would be greatly appreciated.

    Re: General webDB design question(s)

    If you are publishing at this stage to localhost, then your alias is just the default =a5.get_path() and the table are the same for desktop and web (you might not be publishing to localhost, you didn't say.)

    Calculated Field Rules fire AFTER you press Submit on your Grid, if that helps to clarify anything.

    I can't figure out what you are asking in the second paragraph.

      Re: General webDB design question(s)

      Ok, here's a little better description. :)

      I have two working directories. One is an offshoot of my localhost (localhost/test_proj), where I'm doing all my test development and playing around with my database values. Everything works fine as far as being able to view and update the "test_proj" tables.

      I have a table with a calculated field that is based upon the value of a second field in the table and a lookup value produced from another table by the value from a third field(I hope that makes sense).

      Shorthand:
      field1 = field2 + lookup("f",field3,"return","lookup_table","index")

      The problem is that when I update a record in the table, the calculated field is looking up data from the original directory instead of "test_proj", so any changes I make to the lookup table do not show up.

      As far as my second paragraph goes... I just did a bad job of saying "What am I doing wrong?" What's the correct way to get my lookup running right? I feel like I'm just missing some small detail that makes it all fit together correctly.

      Thank you for any help with this!

        I think you might need:

        field1 = field2 + lookup("f",field3,"return",[PathAlias.ADB_Path] + "\lookup_table","index")

        I forget if you need that backslash or not?
