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.

    I also turned off one of our screen repaint optimizations by executing the following command (which you can add to your autoexec file):

    a5.System_Mode_Set("mdi_update_locks","false")

    I will investigate further, but please let me know if these changes fix the problem you are seeing.

    Thanks,
    Cian Chambliss

    Actually, the solution is even simpler. You do NOT have to turn off screen repaint optimization. All that you have to do is tell the browse to repaint, and then scroll to the last record, so that the record you entered is visible. This is the code that has to be entered after the t.enter_end(.t.), in your script:

    Code:
    topparent:browse1.repaint()
    topparent:browse1.fetch_last()

      Thanks so much for the quick reply.

      Cian, to answer your question, we've only seen this with browses at the parent level.

      Selwyn, I found that just doing topparent:browse1.fetch_last() without the repaint also works.

      I had actually tried topparent.fetch_next() and topparent.fetch_last() but had not tried referencing the browse.

      Nonetheless, this is a workaround that was not needed in V7.

        Typically, from the Alpha menus - help - send a bug report. Follow the directions from there to send an email and instructions with an example.

        Of course, now that I tell you the formal way to do it, Alpha found this thread and the posting from Rick and is handling the issue. :o

        It's better to submit a formal bug report than to rely on a random chance find on the messageboard...... :D

            Re: Embedded browse & disappearing records

            hello:

            i have a slightly different situation that is displaying similar traits to what is on this thread. i have a table "comp.dbf" and it has a form that contains an embedded browse from the same table. the table is loaded with values from an append operation. there are two fields that have a simple list lookup and when i enter the field and the drop down list appears the browse disappears. i suspect that it may be a no-no to have an embedded browse from the same table altough it has worked from version5 to version7. any suggestions? i've included the table.

            thanks in advance!

            best regards,

            ed

              I was able to repeat the problem with your form, but if I created a new form (with the same design as your existing form), I was not able to repeat the problem - it worked correctly.

                  hello again:

                  i built a new form and all went well for a few days. then i started to see the same behavior again. restarting windows and compacting the database cleared it up for a few hours. now the data disappears once again. what have i corrupted that could cause this strange occurrance?


                  i'm puzzled at this as the app has been running for over a year and out of the blue this happend.

                  thanks in advance!

                      ed,

                      I just loaded my version 8--first time so it is one of the very earliest builds 1784 3110 and I do not have a problem at all with disappearing browse records. Does it happen right away or is there something special I would have to do to create the problem??

                      If the problem should manifest itself right away and it does for you and others then it must be due to a change from my build and whichever you are using.

                      note--much nicer to have you include the adb with the files so that a new database doesn't have to be created...not a biggie but the easier you make it for people to help the better.

                        In the interactive window, type a5_checkindexesdialog() and select check all indexes.

                        Does this show any errors? If so, then rebuild the indices for that table

                          hello al and mike:

                          thanks for the help!

                          i tried the a5_checkindexesdialog() and it found no errors. i opened the form and it works correctly this morning. mystical ... for sure it was happening but now it's not on either form.


                          thanks again!

                          ed

                          p.s. i'll be sure to include the adb file ... never thought about it thanks!

                            Re: Embedded browse & disappearing records

                            Hi Ed,

                            Just so you can rest assured that you aren't going bonkers (unless we both are) I see the same behaviour in your sample.

                            I would be willing to bet that now that you see it working correctly that you now have more records to view than what will fit in the browse. Ie no empty space in the browse.

                            I found that if I caused the records to fill the browse then the browse behaved. I did this by either reducing the size of the browse in design mode or even just resising the rows in view mode. By resizing the rows in view mode larger and smaller I can make the problem appear and disappear at will.

                            I tried copying the form - no change
                            I tried creating a new form - no change
                            i tried copying the table with all the dictionaries - no change
                            i tried copying the table with just the field rules and build a new form - no change
                            I tried copying the table with only the records and recreated the field rules and a new form - voila problem gone.

                            So I would say ther is something amiss in the table dictionary.

                            Hope this helps.
