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.

    Events and Field Rule

    I have a field rule on a field is called Power which works fine.

    On the form i have an Event that occurs OnDepart from another field. This event checks several fields and when necessary shows a ui_get_text() box to get a new value which is then put in the Power field, using Power.value = val(result string).

    The field rule does not work normally at this point - I get no error message if the value is invalid, simply the entered value IS NOT accepted in the field and the field remains the same.
    If the new value does meet the requirements of the field rule the new value IS accepted.

    Is there a way to make the field rules error messages show up in these circumstances?

    Thanks for any help.

    RE: Events and Field Rule

    Robin,

    In a way, the behavior you observe is unsurprising. The data is no good so it doesn't copy over.

    You have to somehow test for invalid data and create an error when it is discovered and probably also allow the user to correct it as well. This latter requirement suggests that you may need to move the code to the can_depart event.

    If you describe the criterion you need it should not be difficult to invent code to implement it.

      Thanks for the advice Bill.

      I suspected there would not be a way around and yes Alpha is behaving logically.

      Rather use the full formulae i have for the error trap, i have just checked that the new entry IS different from the original. If it is the same it implies the new entry was invlid and invites the user to re-enter.
      A bit lazy but it saved me a lot of work.
