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.

  • table.external_record_content_get

    I'm using: table.external_record_content_get (based on a thread here "Xdialog KeyList Filter Syntax") and maybe I shouldn't be. It's not documented, though it seems pretty straightforward.

    My problem is that it's apparently returning data that is not in the table. Well, two problems, the first being that:


    ?table.external_record_content_get("wprojectselections", "Value")


    Returns data even though the table "wprojectselections" is empty. The data it returns is from deleted records (itself a problem as I don't know how to filter them out) but it does this even though I just compacted the database (which puzzles me as I thought the database compact zapped the tables).

    The other problem, perhaps related, is that the above code returns the exact same data as this:


    ?table.external_record_content_get("wprojectselections", "Value", "", Filter)


    Where "filter" contains a filter that should be eliminating at least some of the records (deleted or no).

    So...I'm not sure how to proceed. Should I give up on this call and use keylist build? (I didn't use it before because I only want the one field and it seemed simpler.) Or do I need further education? :-)

    Is it possible you have more than one copy of the table somewhere. Try specifying the full path to the table

    table.external_record_content_get("drive:\path\ wprojectselections", "Value")
    There can be only one.

      At last count, 50 copies. :-)

      Try specifying the full path to the table

      The records are back. I've had this happen before; I can't remember what, if anything, I did about it.

        RE: table.external_record_content_get

        OK, solved both, sort of. Nailed down the behaviors, anyway:

        First, the query I set up in my code sticks. I was filtering out records so they didn't appear to be there even after the code had run. Running a blank query after I'm done with it doesn't seem to help: Once I've set this query it sticks for the entire A5 session

        Second, the filter I had set up in one place was incorrect (per my other message about getting "T" and "F" out). When you give A5 an incorrect filter parameter, you don't get an error message. You also don't get a filter. I had forgotten that behavior.

        Thanks. Any input on clearing the query would be appreciated.

          OK, more on this. I'm trying to setup a browser filter (unsuccessfully) and so I was using table.external_record_content_get to check out the values that were in the table.

          But apparently this function doesn't care for LOGICAL fields. If I use this:

          ?lookup("sometable", "somefield='somevalue'", "logfield")

          I'll get back a .T. or an .F., but if I want to see all the values in "logfield":

          ?table.external_record_content_get("sometable", "logfield")

          this returns "".

            The .QUERY_DETACH_ALL() method detaches all temporary queries from a table.

            temporary as in not an index.
            There can be only one.
