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.

    User-defined functions in Web Components

    I wonder can anyone clarify whether user defined xbasic functions can be called from within a web app. specifically, i need my app to fetch a sales number from a specific table, use it in the reference field and then update the value in the reference table by 1 for the next record.
    I have this in a desktop form, (courtesy of MikeC), but cannot port the functionality to the web app.
    The Reference field is made up of year and sequential number, e.g. 2010-156, 2010-157,but even if I could use a lookup, fetch and increment procedure to obtain the last part it wouild suffice.
    Any ideas much appreciated.

    Yes. Use the A5W_Load_AEX() function. Lots of help and discussion of it here; use the Search feature.

      Thanks Steve,

      i tried that insofar as I understood the various posts in the forum, however It doesn't seem to work.

      I managed to duplicate the functionality using field rules, using the 'canedit record' event however for some reason the web app grid doesn't implement these 'event' field rules either.

      Re: the aex file - i created this in the code editor section, then ticked the aex option in the publish dialog; i also tried placing the function in the grid execute and grid initialise events, but nothing.

      Any ideas/

        I use them all the time and the only issue I have is getting the .aex file published. So far the only way I have found that works all the time is to delete the .aex file from the server and put it back on with FTP or dragging it in the case of a Lan. If you add a function, for some reason you seem to have to delete the old .aeex file and put the new one in its place.

        Hope that helps.
