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.

  • XD: How to refresh list using external_record_content_get

    Mike Wilson mentioned in a post that he never uses keylist_build, preferring instead table.external_record_content_get(). So I thought I would try that idea. However...I want to filter the list with a combo box variable when the user makes a new selecton and cannot figure out how to refresh the list using this function.

    Basically the idea is the user selects a Customer and the list is filtered to only show records for that customer. Sounds easy doesn't it? It works the first time, but what should I put in the change event for vCust to get the list to reinitialize the array?

    Anybody (Mike?) have an example?

    Finian seems to have the resolution here

    He is using both keylist_build and external_record_content_get in UDF's inside the xdialog...I feel a new learning moment coming on!

      I want to filter the list with a combo box variable when the user makes a new selecton and cannot figure out how to refresh the list using this function.
      **My Simple answer is the "Passing variables "


      1) call a the list function from main function which is showing the Dialog
      2) list function which creates the List box
      3) on the event at main fuction, after changed the listbox value (assumed it is occured at from 4th function ) -- call the list fuction again

        Actually John, keylist_build was easier to use with the genie - unless you can show me an example where you were able to get the other to work in an XD?

        Which may not help me since I can't seem to adapt Finian's script for my use either!

            Good grief John, does that look simpler to you?

            Let me try it in the morning when the wine has worn off...
