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.

    Re: Google Charts using Web Socket data from Server every 5 seconds - Video

    Pete, for a second there I thought you were going to tell me to get my head outta my arse, lol - but I agree, I was just watching the Alpha weekly Q&A where they were talking about the ink control and its pretty cool how you can draw on the image, I currently use another app for that called Paper53 - I haven't made time yet to get into it because of all the other development I have in front of me but I am looking forward to it! I did not know about using it as an image gallery - so I guess I do need to pull my head out and have a look around!

    Cheers~

      Re: Google Charts using Web Socket data from Server every 5 seconds - Video

      My use case is in commercial aviation maintenance. The grid holds thousands of tasks scheduled per week at several facilities each with 3-5 hangars capable of housing a 747. The FAA requires at least half those tasks are approved/signed off by a certified mechanic. The tasks are entered at a single location on desktop browser via editable grid. Workers in the hangars use a terminal to update the progress of a task, or assign "ready for QC". The QC guys sitting in an office with browser open "polling" task list on timer interval. What I want to create is a leaderboard setup where tasks ready or almost ready are constantly ticking towards the top using web sockets to tell the grid "refresh when a status changes". This helps the QC guys plan there day because they drive golf carts miles to whatever hangar is waiting.

      After the worker in hangar clicks submit to update a task - Which client/server event makes the most sense to add "web socket send message code"?

      Send direct from client after successful submit or some sever side event after sql, etc. Looking to reduce the App server load as much as possible. Thanks for any pointers, I inherited this project from someone who was better versed in Alpha, I'm getting there...slowly.

        Without knowing how you're submitting... what you're doing... it's impossible to say. You could be running an ajax callback that takes care of updates. Where ever and what ever you're using to update... it may be at that point you want to send a message. Your comment... "Send direct from client" may indicate you may not understand web-sockets as implemented by Alpha. The web-socket server... running on the server... always gets the message... whether sent from the client or from the App server... and then broadcasts it.

          A lot I don't understand. The grid inserts/edits a single record and is submitted with the stock submit button on each row. Currently 50 or so other users are refreshing on 5 minute interval, want to make that real-time instead. Seems the best option is afterRowSubmit, use Action Javascript-WebSocketActions to send a message from client to socket server. Instead of ajax call back to App server xbasic function doing the broadcast. Both messages would essentially be "refresh now". Was just wondering which approach is more efficient.

            Remember that with a Client-side message, the component sending the message does not receive the message. If you're just refreshing data in a grid, then afterRowSubmit with Client-side message sounds pretty good.

              Thanks for the confirmation David. If and when I can finish this I'll post a video of it working. I think it might be of help to others in the same confused state.

                The single simplest thing you could do is change the submit button so that it refreshes all other grids (using a socket message to fire the event) when it is clicked. you would just need to add the javascript in the section that listens for messages. Then turn off the 5 minute refreshes as they would no longer be required. You can elect not to refresh if the Grid is dirty incase someone is entering data, then once they submit it will all refresh again. - good luck.

                    Actually I found it here
                    https://www.youtube.com/watch?v=RfLDJ4-oYNI

                    Your link was not the right one, any-who I looked at the release notes but the videos would NOT load from there for some reason for me so I found it on YouTube.
                    Alpha is pretty good about spreading out the resources so you can find what your looking for.

                    Thanks again for pointing out the image gallery option, looks pretty awesome.
