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.

  • Pack script error

    Hello- I received an error message from a script I wrote in Alpha 5 version 9. The script read:

    Script:FinalAppend line:47
    Table in use by another user or window

    I just installed version 10 full and runtime database locally on my machine for testing before I deploy out to the server and upgrade. When I comment out the pack(), then the program runs, but my table doesn't pack as it should.
    I tested this script out in both runtime and full version and the error still appears and stops processing at this point.

    Is there something different in version 10 that would cause this to happen?

    Re: Pack script error

    Might be a timing issue. From the script name can we assume some append processing precedes the pack?

    I would suggest following whatever prior code you have with

    a_tbl ="sametablename",FILE_RW_EXCLUSIVE)
    'any other code here
    There can be only one.

      Hi Stan-

      Tried your method and the new error says The process cannot access the file because it is being used by another process. From reviewing the script attached, is there any reason you can see that Alpha 5 version 10 produces this error while it works with no problem in version 9?

        Re: Pack script error

        That still indicates a timing issue. Try it this way with the append inside a function.

        And no, I don't see a reason it should behave differently.

          Hi Stan,

          I have often seen mention of converting an action script to Xbasic and putting it into a function.

          Is it as simple as just creating the function as you have done
          ? ie. Making it Logical and enclosing within:

          FUNCTION app_code as L()
          app_code = .F.

          Scrpit goes here.....

          app_code = .T.
          END FUNCTION

            Re: Pack script error

            Yup, just that simple. You can add error checking but the basics are in my attachment. If you capture the xbasic of an Alpha generated append you will have the error checking it adds.

            The reason you make the script return a logical type is so that you can say

            if functionname() 'returns true if the script completes, false if it doesn't
            'do this
            'do that
            end if

            Setting the return functionname = .F. means that if the script in the function doesn't finish then the line functionname = .T. never executes and you can test for that.
            There can be only one.

              It is actually easier, but returning a logical just makes it more Script_play() equivalent and has the advantage outlined by Stan.

              However, the benefits are enormous for more reliable operation. See my tips here.

                Since I upgraded to version 10, I have had to make adjustments to my code so that it works. My prior version was 9. I don't receive the pack script error now, however, form doesn't work as before. In version 9, my calculated fields updated when typing values into a non calculated fields. Since I have copied my database into a new folder and started using version 10, the calculated fields do not update automatically when entering values into a non calculated field as i have it setup. How do I go about having this work for version 10? My database have massive calculated and non-calculated field, therefore, I hope I do not have to re-create everything.

                  Neecy, is this latest issue related to the pack script error? If not, consider starting a separate thread to keep the discussions separate.

                  Regarding the pack script error you did you get the problem fixed? What did the solution look like?

                    Re: Pack script error

                    Hi Tom-

                    This does relate to the pack error. The pack() worked in version 9, but doesn't in version 10. It appears that many of the scripts in version 9 requires me to modify my code for version 10.

                    The pack script error didn't disappear at all. The only resolution I could use was packing the table using pack() into another script. Although it appears to be a timing issue from where I originally had it, after going through the suggestions given, the error still said it couldn't pack the table because the table is being used by another process. The table was closed before the script to pack was initiated.

                      Hello, Anissa.

                      It seems to me that a question about getting calc fields to update is a very different issue than a question about why a script that packs a table is failing. Suggest you begin a new thread when there's a different issue you have questions about. It will get better exposure and will be easier for others to find when they have similar issues later on.
