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.

    Key_unique() Error

    Hello All
    I have this simple uniqueness code in the Cansaverecord rule.

    if .not.deleted("shipment_details") then
    if .not.key_unique("Detail") then
    cancel()
    msgbox("Duplicate","This Item already exists!")
    end
    end if
    end if

    The index called �Detail� is a combination of three fields (shipment_no+style_no+drop).
    I get this strange error :�Variable �Drop� can not be found.
    Can anyone tell me what I am doing wrong
    Thanks
    Nick.

    Suggestions.

    1) Look at the value of [drop] inthe interactive window (IW).
    2) Build the Idx with Trim around the detail
    3) Create Calculated field in the table which is with the trimmed concatination of shipment/style/drop. Use that as the index root.

    Apologies to anyone I haven't managed to upset yet.
    You are held in a queue and I will get to you soon.

      Where is drop defined/dimensioned? What scope is it given?

      Dimension and give it the same scope in the Cansaverecord event script.
      There can be only one.

          The strange thing is that “Drop” is not a variable .it is a field of the table being edited.
          Thanks.

            Nick, it seems to me that if your script worked correctly the user would never be able to save any changes to a record after it had first been saved. The canSaveRecord event would get canceled unless the user happens to change one of the three fields that make up the compound index key. If I were you I'd do this kind of validation in the form level events where my script would be able to tell if the user were entering, changing, or deleting the current record.
