Modern web browsers have been designed to protect end-users from malicious or unwanted access to computer’s local resources. Typically, web browsers have none or limited access to disk units, USB devices and peripherals devices attached to the local computer.
Local printers are not an exception; they are restricted to printing web content only. But what if our VirtualUI-enabled application needs to send raw print commands and data to a matrix or label printer such as Zebra, Epson, etc.?
This article will demonstrate how to access a printer connected to the web browser from our application so we can generate RAW prints remotely as if the remote application and the printer were available in the same environment.
In a previous post we explained how to add remote data persistence to your apps by saving cookies in the browser. In this opportunity we will take advantage of this feature to develop a small but useful demo that shows how to provide an extended sign-on for web users.
Thinfinity VirtualUI web enabled apps were born as desktop apps and most include their own login mechanism. In this opportunity, we will show you how to extend your own existing application’s sign-on process, getting the browser to identify the application’s user. In this way, users would only need to manually log in when accessing the application for the first time, after logging out or when the login ID has expired. Continue reading →
The Thinfinity Remote Desktop‘s toolbar allows users to perform some of the actions which are essential for a complete remote user experience, such as sharing the current sessions, accessing the file transfer manager, changing option settings, etc. In a previous post we discussed how to remove toolbar options. In this opportunity we will show you how to extend the Remote Desktop’s toolbar with new “Send Key…” actions. Continue reading →
Last Friday we announced the beta build of Thinfinity VirtualUI v2. We are excited about this new version because it includes several new major features that take VirtualUI to a new level of virtualization and integration.
In this opportunity, we will learn how End-User Authentication works in VirtualUI web-enabled applications. Continue reading →
At first, the file handling dual behavior in a Thinfinity VirtualUI web-enabled application can appear to be a bit confusing for new developers and users who are accustomed to running the application from the desktop. It’s actually pretty simple, as you will see in this article.
A distinctive characteristic of VirtualUI web-enabled applications is their ability to be executed from the desktop, as usual, and also be called through a Thinfinity VirtualUI Server to be remotely executed from any modern web browser. This web enabling process, however, will most probably need some testing and debugging. A comparison stage between both the desktop and the web running mode is also often essential in order to fine tune certain details. This is why Thinfinity VirtualUI was prepared to run web-enabled applications from the IDE, working together with the development environment you use when running the application in debug mode.
