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.

    Nick, that's not necessarily so. G's question is a good one.

      Yeh..so, something you do in between the time you show the form, til the time it is closed, that keeps the table open or opens a second instance of it.

        Re: tables are left open

        For what it is worth,
        I solved the problem .It turns out that I had a Listbox.control on the form.
        The data source for the choices of this control was a set .I found out that if the choices are filtered using
        Properties>choices >Computed Automatically>Table/Set window .The listbox will populate correctly but every table will be left open when the form closes with no error .You can call it a bug or a limitation .I
        Populated the listbox using Xbasic �settings.dynamic_list� .It all works with now open table.
        Thank you all for the help and the information.

          Nick, that's great news. Glad you found the cause. It sounds like something that should be reported formally to Alpha. Have you submitted a formal bug report ?

          Also, was the listbox control on the called "dialog" form?

            Re: tables are left open

            Emphasis being that ONLY when the listbox data source is a SET does this problem occur. Is that correct?

              Re: tables are left open

              Ray, I'm curious about that, too. I typically base listbox controls on single tables. I wonder if the problem would be resolved by basing the listbox on a mapped table ?

                Re: tables are left open

                As I said, there is something that happens between opening the form and the last line of the script and that thing evidently is the listbox.

                There is a bug there but not having your version I can't test for it.
                Adding a listbox to a form, based on a table or a set, should not open the table(s).
                In my version, I added a listbox based on a set and tested. The first time around, I saw that there were multitudes of instances of the tables from the set that were opened and remained open. I was about to call the cops and report a bug. Then closed alpha and re-opened it and re-tested. Now it is behaving as it should, i.e., adding a listbox based on a set DOES NOT open any of the tables from the set.
                Can't explain why it happened the first round I tested as I am not able to reproduce that error anymore, nonetheless it did happen. Do not know what all the other circumstances were. But the fact that it did happen under certain scenario and/or if it happens in your version with some sort of consistency, then there is a bug, or could be a bug on the fly pardon the pun that shows under certain circumstances.

                So, there is a bug (or bugs) when adding a listbox to the form.
                I'd report it if testing in your version continues to show the same behavior.

                  G,

                  Since the listbox is not populated with static values Alpha has to open the table / set to get the values in order to populate the control... but it should then quickly close those tables because they won't be needed again. It's this "clean up" work that is not getting done... and perhaps that's because the data source was a set ?

                    Re: tables are left open

                    I wonder if he can change to Populated using Xbasic and provide the choices to the dynamic_list property with a suitably constructed

                    SET.EXTERNAL_RECORD_CONTENT_GET()
                    There can be only one.

                      Tom:
                      Yes, alpha would access the tables and close them in the same manner you would via xbasic. I am not sure where the ball is dropped. I can't test for that.
                      Here is something you could test: Do everything in the same way with the exception of opening the form as a popup instead of dialog and see if that makes any difference.

                        G, I think that's a good idea, too.

                          Re: tables are left open

                          I have realized that if a set is filtered and the order expression has fields from the child or grand child tables, the filter has to be flattened for the filter to work correctly. In my opinion this is the biggest weakness of Alpha .Since the choices window does not allow you write your filter expression it does not work . I did “EXTERNAL_RECORD_CONTENT_GET()”.

                          Thanks
                          Nick

                            It does.
