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.

    Is referential integrity form dependent?

    A parent form is defined with a button to open a new form to display child records.

    This is done using the Action Script Open Form or Browse layout, displaying all or selected records in the layout.

    The child form contains an embedded browse to display all records related to the parent.

    The following settings are made in the Action Script:

    Code:
    Show which records in the target form or browse: 
    Records that match the value on the current form or report 
    
    Show records wheere the value in field:
    Person_Id
    
    Matches the value in the control:
    Person_Id
    When new child records are added to the newly opened window, and the record is saved, the following occurs:

    1. The child record's child key is correctly created
    2. The child record's parent key is blank.

    Why isn't the parent key being written to the child record?

    If the browse is placed on the parent form, instead of on a separate form, then the parent key is successfully written to the child record.

    I was hoping that referential integrity meant just that: that it enforced table relationship consistency and was not dependent on how tables were maintained on forms.

    Re: Is referential integrity form dependent?

    RI is not happening because your called form is not based on the set for which RI was defined. The called form is based on the child table, alone, right? RI is dependent upon using a data entry layout that's based on the same set for which it was defined.

    There are a variety of ways to pass field values between forms. You may find the examples in the Code Archive forum useful.

      Tom,

      Got it!

      My mistake was that I was open using the child table with the child form.

      When I changed the child form's table from the child table to the parent set which included the child table, both
      the child key and the parent key were successfully written to the child record.

      Thanks,
