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.

    UDF Variables

    This is my first UDF. I wanted to display a list of variables (global, session & local) during the design and testing of an application. This function (aptly named Variables) lists all variables to help resolve confusion or to just satisfy curiosity.

    I have placed it on the Form View System Toolbar, but it could equally be placed on a specific form.

    ' show the list
    ui_msg_box("Variables",to_show)

    If anyone sees how or where this can be improved, I'd appreciate it.

      RE: UDF Variables

      I ran into a lot of long CRLF() strings in my variables so
      I've attached a revision that cleans up the output display and allows a choice of showing the full crlf string or just the first line.

      It also allows you to export the list to a text file but the alignment of columns isn't very good unless you set your default .txt file viewer to something better than Notepad and set your tabs manually.

      Some of the lines of code got rather long so I attached it as a txt file to avoid wrapping issues.
