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.

  • How to determine that a single value in a group meets conditions

    I have received tremendous help on many issues in the past few weeks. Thank you to all. At the report level,
    I am trying to display when a value meets certain conditions in comparisons with other values within a group.

    For example, I have group called race which may contain up to 14 records. Race is a N Field.
    There are other values in each record, that I would like to identify when these fields are alone/single in their group.
    For example, Field 2 (C) has values blank or X. If the X value is solo in the group, I would like to highlight this on the report.
    I am not sure how to approach this and what functions would be used to identify a solo X.

    Any help would be greatly appreciated.

    Thank you

    Re: How to dtermine that a single value in a group meets conditions


    with a filter expression which limited the record selection to those in the current group and with the current field2 value will return a list of values or only one value if the current record is a solo. So if the count of the return values is 1 it's a solo.

    You can "cascade" pointers and methods in many cases so in the context of the report you could likely use

    table.current().RECORD_CONTENT_GET( "race","", CURRENT_FILTER_EXPN()+" .and. race = "+race+" .and. field2 = "+quote(field2) )

      Actually seems to work.

      Expression used.........

      line_count(table.current().record_content_get("Td_Race","",current_filter_expn()+" .and. Td_Race = "+td_race+" .and. td_date = "+quote(td_date)+" .and. r3_type = "+quote(r3_type)))

      Note: The field used as the first parameter, record_content_get("Td_Race","", is not important. We are only checking to see if we get one line of return values or more than one line, not the content itself.
