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.

  • Ajax callback from mobile app

    Hi All, I'm exploring the possibilities of using a mobile app to scan some bar/qr code and then retrieve data from a sql server database based on the information from the scan. So far I've done a couple of tutorials on how to create a mobile app using phonegap, and that works fine. The issue I'm having is when I do the ajax callback to my xbasic function. It doesn't seem to be taking place. I know there is information being read by the scan. I've run my UX in working preview (non-mobile) to test that the callback works, it just doesn't seem to fire when I do it from my android mobile device, where I installed the app. I'm not sure if there is something that I'm missing or not, or if ajax callbacks require different syntax to go from a mobile device to the alpha server.

    Thanks in advance!

    Poking around some more, it appears I need to specify a url for ajax callbacks in the phonegap build window. Trying to find out what exactly that is, it just says local webroot in the publish dialog.

      You want the actual URL of your site in there... including any specific ports if that's how you've configured your server... including the http:// or https:// prefix. E.g. or

      When you open the builder for this section you'll find lots of specific help.

      If it's just localhost you're testing with, then there's a link in this section to tell you what your local IP addresses are as well.

        Thanks David. I found the local IP part you're talking about, and I did publish my UX. I need to talk to the person that setup the server here to find out the other specifics. The mobile space is completely new to me.

          it just says local webroot in the publish dialog.
          this is for testing purposes only when you develop. if you want to publish to be reached from outside, then create a new profile call it any name you want and publish to that profile.
          since you are using dbf you will need to publish the data too.
          the ip address you've been saying, i wanted to point out, is internal ip address. i do not know phonegap build will reach that ip address. (i won't know i don't have version 12) but if you talk to your IT guy he can port forward to that server where your data and the app resides, and you can direct the phonegap to reach that outside ip address.
          while theoretically speaking you should move on to sql of some flavor, alpha will work well with dbf backend. the publishing or phone gap should not affect what backend you are using, as far as i know.
          thanks for reading

            I did finally get this to work. Some simple configuration mistakes. I ended up publishing through one of the profiles in another workspace we have, I just needed to get a proof of concept out. I am using sql server as a backend, so there shouldn't be any issues there.

            Thanks for your help!

              my apologies.
              i mixed up with another post that also had local ip address along with dbf they are using, however my suggestion based on the local webroot on this thread is correct.
              i am happy that you solved your present problem.
              good luck for further progress.
