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.

    Clearing fields

    My form has several fields. On a button push event I execute the Clear Fields action in which I have listed the several fields. When I run this I get the following error message:

    Script: OnPush line: 10
    topparent:Artist.text = "
    Error 8011

    The code was generated by Alpha 5, so what does this mean?

    RE: Clearing fields

    Leo, you might want to spend some time in the tutorials. Field objects in your form are bound to the underlying table. If you "clear" the field, you're wiping out the field value in the current record. Is this clear?

      RE: Clearing fields

      I assume that a cleared field does not have its value stored in the underlying table until the record is saved.

      Here's what I'm trying to do; a partial entry has been made into the fields of the form and the user wants to clear out all fields of the form and start over. Hence, a button that clears the fields of the form without saving.

      So question one is where have I gone wrong using the Clear Fields action? Question two is what is Error 8011 and where, if anywhere is it documented?

      Leo.

        RE: Clearing fields

        Wrong!

        Unlike other database packages or lower level languages, Alpha Five's forms are already bound to the underlying table. If you "clear" a field you're overwriting the current record buffer's value for that field. If you then save the record (accidentally, or by filling in new field values on screen) you're again overwriting the buffer. When the form saves the record you'll find to your dismay that the original record has disappeared, replaced by the one your use filled in, after you so carefully "cleared" all the field values in the current record.

        If you have a partially completed new record on screen, your form is in ENTER mode. Your script to "start over" should simply cancel the ENTER, and then, in a second step, begin a new record.

        If you have an existing record on screen, and you 'clear' its fields for data entry, your user will be overwriting the field values in the record originally displayed on screen.
