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: Access a Desktop Application thru RD

    From an application standpoint, would they be able to be isolated to run multiple instances of the same Alpha application so it appears they are accessing many desktops?
    I like to learn new things if I can and this sounds interesting.

    Thanks!

        Interesting is also that if you use xdialog with Chrome control you actually can build responsive desktop applications which act very similar like web applications but has advantages of desktop.

        This above and TSPlus (or similar) and runtime and node intergration makes AA Desktop a Beast.

            Gosh,
            If I only knew what all that meant. It seems Kenneth is leveraging AA Desktop to capabilities that I certainly could not conceive, but sure would like to see.

              Re: Access a Desktop Application thru RD

              Here are some old examples:

              Xdialog responsive layout and JQuery,

              Xdialod and KendiUI-Spreadsheet and Spreadsheet upload to AA Was server and download back to filesystem and spreadsheet open again locally,

              Xdialog and Nodejs.



              This all of course works also with TSPlus.

                Kenneth, Good stuff! You seem to be one of the few posters that has been using the desktop web components option. If you could help with some questions regarding the examples because the documentation barely explains any of this.

                1) The responsive layout form. Did you create the form as a UX then use the create Xdialog genie...or use an Xbasic script to open the UX...or just create from scratch?

                2) Using Kendo in a desktop app. Where do you place the 3rd party js libraries and how do they load into an xDialog?

                3) Xdialog and Nodejs. Are you using the Alpha built-in Node server and if this is a runtime app where are you hosting that server. Or can you use an independent server on a remote machine?

                Thanks

                  I am actually not using any UX components. I use xdialog and Chrome control.

                  1) This is made with Bootstrap3(2017) and JavaScript and css and xbasic in xdialog. That's all.
                  For example css is loaded
                  Code:
                  <link rel="stylesheet" href="a5file://C:\alphatesting\budget\assets\css\site.css" />
                  bind event to submit (DOM):

                  Code:
                  dim mapping as c 
                  mapping = <<%txt%
                  b1|click|event1
                  b2|click|event2
                  %txt%
                  cp.AddEventListeners(mapping)
                  and fire event:

                  Code:
                  if a_dlg_button = "event1" then 
                      a_dlg_button = ""
                      dim scr as N
                      scr = cp.GetValue("totalhours")
                      ui_msg_box("Development hours:",scr)
                  2) Everything runs in Xdialog. You make first Chrome Control available
                  Code:
                  dim cp as helper::Chrome
                  Then there is two option how to load external js. You can use local filesystem (maybe the best option) or from web (CDN).
                  There is two option from local filesystem (a5file: of file:) For security reasons you have to disable chrome control security:
                  Code:
                  cp.flag_web_security_disabled = .t.
                  but in my opinion just a5file currently actually works but in old version of Chrome control both did work.

                  3) I am using Alphas Node and xdialog. It is basically just a xbasic function you have created (with node and xbasic) and then you just run it. But you can do whatever. Nothing is impossible.

                    By the way here is one nice example more what one can do with Alpha Anywhere Desktop.

                    In left there is a web browser and in right there is Xdialog and THEY COMMUNICATE TOGETHER IN REAL TIME.

                    Note the web page is running in Amazon AWS S3 and so the web page is just a static web page.

                    Here is the link.

                      Re: Access a Desktop Application thru RD

                      Thanks Kenneth. That's very helpful and a clever way to use the desktop version. I was fumbling around with opening up grid/ux components in an xdialog but it wasn't very smooth/responsive. Will give you suggestions a try.

                      And sorry for the thread hijack. Another RDP option if you have very low usage (e.g. an hour or two per day per user) is AWS AppStream. Essentially, it's a Terminal Server session running in a browser. You still have to pay the $4 month CAL per user and then something like $.10/hr connection fees. BUT, Amazon handles all the hardware and system updates. We used it in the past for Alpha Runtime apps and it worked flawlessly but got expensive once everyone wanted to use it, so we went back to local PC installs. I didn't set it up so can't help with any technical details.
