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.

New Record Entry Issue - Data disappearing

  • New Record Entry Issue - Data disappearing

    Does anyone know of possible causes for data to disappear during record entry? Only the currently selected field is affected.

    - The record does change state (save or cancel), it remains in entry mode
    - Occurs on different machines and different fields but all during record entry.
    - Issue is intermittent but happens a couple times a day (once about every ~20-30 records entered)
    - Data is entered on a form connected to a DBF table

    for some reason I don't see an edit option to my original post but would like to make this correction to the above:

    *The record does NOT change state, it remains in entry mode when the data is cleared from the field.

      You mention multiple machines, so, is the table being updated open somewhere else? It's possible that the record is open for editing, or left hanging so check the status of the record you have issues with.

      Are you running several machines from one Alpha instance, or multiple shadowed instances?

        Hi Ted,
        Thanks for the reply.

        This happens across machines and across tables. I just tested on a form to a table that I can confirm was not being updated elsewhere. All the other fields with data in them on the unsaved record remain intact and only the current field loses data. Also, this is a new issue but we haven't changed users or settings so what would trigger it...

          The record does NOT change state, it remains in entry mode when the data is cleared from the field
          Which of these most closely describes what is happening?
          1. As the user types in keystrokes into a field, the keystroke values do not show up in the field
          2. As the user types in keystrokes into a field, the keystroke values do show up in the field and the user can see what they have typed but upon further typing into the field the entry disappears.
          3. As the user types in keystrokes into a field, the keystroke values do show up in the field and the user can see what they have typed and they complete the field entry but then when the field looses focus, the entry disappears.
          4. As the user types in keystrokes into a field, the keystroke values do show up in the field and the user can see what they have typed and they complete the field entry, and when the field looses focus, the entry is still present, but as they are entering keystrokes in another field, the entry in the prior field disappears.
          5. As the user types in keystrokes into a field, the keystroke values do show up in the field and the user can see what they have typed and they complete the field entry, and when the field looses focus, the entry is still present, and they enter keystrokes in other fields and the entry in the field of discussion remains but at the event of saving the record, the entry in the field of discussion disappears and the record remains in enter mode.

          Data is entered on a form connected to a DBF table
          Is this issue specific to a one, single form and table only?

            The only time I have ever seen anything like what you describe is with a form at the set level, not with a form at the dbf level.

            If a parent and child are not rigidly linked, I have seen data disappear as it was entered.

            Are these forms definitely attached to tables, and not sets? Is there any chance a linked table has orphan records that get created every 20 - 30 entries???

            It would help a lot if you zipped up a sample. This is not likely an issue with AA itself, as in a bug. It's probably a snippet of code or a field rule or something that would take months of us guessing to get at.

            I do miss Stan Matthews being around, as he seemed to have a crystal ball with things like this. I mean, we would like to help, but it's just guessing as we don't have the issues you are experiencing.

              A long time ago, in a galaxy far far away, i recall something similar happening when wireless keyboards were being used on multiple work stations, and some of them happened to share the same frequency. I think this is very very unlikely. But what you describe is very very unusual.

                When M/s is carrying out an update, I have noticed spurious problems.
                The Win7 machines are particularly affected.

                  Thanks for the support thus far guys.

                  I've investigated some more and here's what I've got:
                  1) happens irregardless of the form being tied to a set or a single table.
                  2) happens on both a remote session (users on win7 and win10 are running remote session into a windows server 2016 machine), as well as on a shadow copy
                  3) happened to me using a hardwired keyboard
                  4) can happen on any field but only during entry mode.
                  5) can happen within 5 seconds but can also can take up to a few minutes. Sometimes doesn't happen at all.
                  6) nothing strange is noted in the trace window

                  Any other way to run a debug of some kind to try and catch what would trigger it?

                  Is the fact that I'm using DBF's in a multi-user environment a possible failure point?
                  Otherwise, would the remote sessions all accessing a runtime version possibly cause this? How do you guys have your multi-user environments setup?

                      Q - It's beginning to sound like your users are connecting remotely, and not using separate workstations on a local network. You might furnish specifics on how the remote connections are being done - possibly this will lead to other ideas for what's going on. In the meantime, you might investigate whether this EVER happens when no remote connections are occurring. And, does ALWAYS happen when multiple remote users are connecting?

                        I can say it has nothing to do with limits to DBF's used by many users. Many of us have hundreds of forms running on hundreds of tables for decades.

                        Let me use an imaginary example to clarify by using the details in your opening post in this thread.

                        A form has 5 fields from a table on it. You start entering, and as you move from, say, field 3 to field 4, field 3 goes blank?

                        A few successful records later on that same form, field 1 goes blank as you move to field 2?

                        If that's what is happening, I'm thinking this is not an installation setup issue.

                          Are there any field rule events, or OnTimer events of these forms? A custom toolbar?

                            Onother suggestion.
                            If you copied and renamed any tables into a different instance, I have had issues where Alpha is using the old table location which caused issues.
