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.

    Another Freeze by A5

    See attached file. Open SESSION form and click on any of the 3 buttons to open AttendanceForm. Sort by LastName, modify a record then try to move to another row or save, A5 freezes.

    Re: Another Freeze by A5

    Gaby, I think you've found a bug that should be reported formally to Alpha. Use the Help button to find the "Submit a Bug Report" option. Include a copy of your sample database with instructions to be followed in order to see the fault occur.

    what's happening is this. Your scripts are setting a base level query in the called form. The called form rests on top of a two table set that has a one to one link. The base query is filtering records based on a field in the primary table. The error occurs when the browse object tries to sort the browse using a column from the one to one child.

      Re: Another Freeze by A5

      Hi Tom:
      Thanks for your feedback. This puzzled me and suspected it had something to do with indexes in one of the 3 tables. I then started deleting indexes 1 by 1 and putting them back until I deleted Sessid_fk in the target table (child table) and things got back to normal. This index is built on the linking field between the calling form (Sessions) and the called form (AttendanceForm), it is the field A5 is building the base query on in the child table (Attendance table).
      Could you please delete the Sessid_fk index in the Attendances table and see how it goes. BTW I did not create any of the indexes, they were all created by A5.

      If I recall from my very fuzzy memory from FM, it seems (and i may be wrong) that you can't index the linking field in the child table without running into trouble. It's probably the case with A5 or I am way off and it's something else.

      Later...
      I put the index back and things are fine; so what I said above does not hold. Probably it was a bad index that needed to be deleted and replaced???
      If in light of the above info you still feel that it's a bug, please let me know and I'll send a formal bug report.
      Thanks for looking into this.
