How to communicate a web app with destkop app?

+1 vote
81 views

I need that my web app talk with a dektop application.

User case: a user click a button on the page, and this button send a command to the desktop app and wait for the answer from destkop app or timeout.

I am using Rails 4 and Qt/C++, but it is not mandatory to use Qt/C++. The desktop app is used to talk with computer usb port. Anyone have any tips or help?

Which computer is the web application running on (not the browser, the rails server)?
Rails server is running in a VPS with nginx and unicorn.

So the server is running on a different computer to the browser, and you want a page in the browser to interact with an app on the PC running the browser. I believe this is not possible, and nor should it be possible. Would you want a web page to be able to affect applications running on the PC? Imagine what a malicious website could do if this were possible.

Does is it an alternative for you?

Without the desktop layer, in this case.

       GraphClass.gauges[name] = new Gauge(name + "GaugeContainer", config); // **In this line it shows error in eclipse emulator but correct in browsers**
       GraphClass.gauges[name].render();
   },
createGauges:function()

    GraphClass.createGauge("cb_graph", "Calories Burn",0,2600);

updateGauges:function()

When I try to drag an app between workspaces, it doesn't move. I'm using compiz. When I put an arrow over an app in the workspace panel viewer (whatever that is called), it says click to start dragging, but no go.

Any ideas?
