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.

  • dymanic widget/control events definition

    Following these videos showing drag and drop functionality between two list boxes and wanted to find out how I would dynamically define widget/control events as part of a general workflow where other settings to controls are happening in given situations.

    I've read this a few times but I could only guess at what you're trying to ask... but it'd be clearer if you provided a scenario that illustrated your question.

      Re: dymanic widget/control events definition

      Javascript events defintion at build time are ok if you know before hand what operations are needed, with all the switch cases that they may need. But a scenario might be that a dynamic ux view might need that function re-written in some fashion hence a need to be able to define the function say the onClick event for a button to perform this new task an maybe return the original function back to the definition in other circumstances.
      My thinking is that these code events can be defined say in the database as part of the data store. In this case, looking at the events list will show none defined as the image indicates since the functions will be "attached" to the controls at runtime. Hence the question is how-to create the functions and associate it to a control, something on the lines of addClass() in javascript when chaining classes to a control.

        Re: dymanic widget/control events definition

        I understand now what you're asking. I'm not sure the environments we have to work with are conducive to this type of process. It would be a lot of work to build something which could scan and replace sections of a UX in code. Further, it's fine to have your "dynamic" code sitting in the database but you'd have to initially write that code, test it, then save it. You'd have to have another full process for design which would build the UX for you in design mode, allowing you to change and test code, then update the database. How many "versions" of a UX would you have that would contain basically the same controls, but have different code for different events for each control?

          The mentioned scenario might be a one off but more to the point, the how-to since the videos show a list control implementing drag and drop functionality and wondered how I would add this feature/functionality to other controls. The code in the videos show

          Code:
          $e.add(lObj1.contId,'abstractdownhold',function(e){
              //code here
          });
          My trial was to just add an event to a control as follows for a button and a text (satic) control, in each case, this failed. did also try the 'abstractdownhold'.


          Code:
          var btn03 = {dialog.object}.getControl('BUTTON_3');
          $e.add(btn03.contId,A5.d.evnts.click,function(e) {
          	alert("Event Click!");
          });
          
          
          var st4 = {dialog.object}.getControl('STATICTEXT_4');
          $e.add(st4.contId,'abstractdownhold',function(e) {
          	alert("event mouse down!");
          });
