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.

    Repopulate Combo Box

    Hi All,

    Does anyone know of a way to repopulate a combo box on a form using xbasic?

    I have a combo box that is populated with unique records from a table and I want to update the list after I delete a record.

    It works if I close the form and reopen it, however, I want to leave the form opened.

    Any help is appriciated.

    Thanks,

    Scott

      Scott,

      Is 'combo box' what it's called in the toolbox?

      Since there are several different listbox choices and none of them seem to be named 'combo' I'm confused.

      (btw, situation is normal... I'm easily confused!)

        Tom,

        I can relate to your confusion .. I tend to suffer from CRS myself :)

        Its called a combo box in the object properties .. Its a dropdown list object.

        Sorry I confused you ...and thanks

          Scott, no apology is necessary!

          How are you populating the listbox initially?

          Could you post a copy of the database here? ... or at least the tables & sets and their dictionaries?

            Scott,

            There's a section in the Xbasic Ref. Manual called 'Working with List Boxes, Combo Boxes, etc.

            Looks like you have the choice of either manipulating the choice array directly, or of repopulating the entire list box.

              Tom,

              Thanks for the interest. Initially the list box is computed automaticlly based on values of a table. This is all done from within the object properties choices tab.

              I managed to find a work around, or maybe the right way to repopulate the list box. I used the WATCH expression in the filter expression by creating a layout variable that I use as a switch to trigger the watch expression.

              I can live with this. I was just looking to do it in xbasic. There is more important things to burn brain cells on .. :o)

              Thanks again

              Scott

                  Scott,

                  If you download my DATDOC from the code section, you can
                  look at the populate_choice script to see an example of
                  how that is done.
