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.

Using UDF in Alpha V12

  • Using UDF in Alpha V12

    I wonder if anyone has any suggestions to solving this problem:

    I have a user defined function which return a numeric value into a calculated field in my Report based on a dbf file. I have created an .aex file from the Control Panel.

    If I run the report from the control panel I get the expected result.

    Total No. Male No. Female Average Median

    1256 860 68.47% 396 31.53% 66.91 69

    However, when the report is created using a5w_report_save function from a Dialog component and run using Live Preview, the UDF generated calculated field does not update as shown below

    Total No. Male No. Female Average Median

    1256 860 68.47% 396 31.53% 66.91 med

    med is the calculated variable in the report which is assigned the value returned by the UDF.

    I have copied the .aex file into the database, the live preview and the A5Webroot folders. The Development Server is also started.

    Any help would be appreciated.

    Kind regards

    Raj

    When you publish you should select the option to compile the aex and publish.

      Hi Garry

      Good morning and thank you for your reply.

      Yes, I have selected the option to compile the .aex, stop and start the Development Server, but still will not work.

      I created a new UX component, on a button click I added a javascript action to open the Report with the UDF. In the Properties for the UX under Other I added the
      .aex file against Xbasic .aex Files. In this case the Report is generated correctly if I select "Working Preview" but not if I select "Live Preview" (both with IE and Chrome).

      Regards

      Raj

        I haven't used AA webserver much where I've made adjustments to UDF, but with V11 I often
        have to restart the webserver to get the new UDFs to be recognized.
        Bad news is it's a PITA, good news is it doesn't take much effort to reboot AA webserver.

          You don't need to restart the web server to get your aex UDF's updated. Just create an a5w page with this code and run the page after you have published the updated aex:

          <%a5
          Server.ClearAEXCache()
          %>

            Peter,
            I know that method is supposed to work with V11, but the reality
            of my experience requires a server reboot.

              I wonder why? My experience is that it works 100% of the time in v11 & v12. Never had a problem with it - and I use it, and have used it, extensively.

                Gregg and Peter

                Thank you both for your replies.

                And Best Wishes for 2019.

                I have tried the solutions you both have suggested but I am still having on luck with the UDFs.

                Strangely, there are no error messages and it appears as if the UDF does not execute (get called) when the Report with the UDF is generated from a grid component.

                This used to work fine in Version 10.5.
