Dear Friends macusers, the approach of Christmas, we need to be charitable, particularly towards users of Windows PC. Indeed, before the influx of requests on how to control a Windows application from an iPad, not having provided a tutorial (*) for Mac users, I feel indebted to a small tutorial for windowsusers.
For your iPad can control the screen of a PC, you must first create a network of "Ad-hoc" on the PC (Windows XP, NT, Vista et 7). From Windows 8 and 10, you can, either follow this tutorial, either connect your PC and your iPad via Wi-Fi to a router or a Wi-Fi access point (for example a multiplexer, un Iridium GO!, or an AIS-WiFi present on board). PC side, if it does not have a Wi-Fi card, a simple WiFi-USB key will do the trick.
The Windows operating system, unlike MacOS, not offering native function remote screen sharing, must install and activate an application VNC (Virtual Network Computing) server, such as the application TightVNC, free and easy to use (although not translated into French).
Once installed, TightVNC server is default enabled (otherwise it is accessed by the "Start" menu in Windows) and an action icon is added to the taskbar, to manage the use of VNC. An overview of the icon with the mouse displays a "tooltip" with the IP address to use to connect to the server.
While install processing, the server asked to create a password for login, and possibly a password for viewing only. The configuration window allows you to change the connection settings.
Then need to check, in the Security Center, the Windows Firewall accepts TightVNC inputs.
Download a VNC app. The simplest, Mocha VNC, offers version Lite for free, but it cuts out after 5mn. However, this allows you to check that it is working properly.. For permanent use, you have to install Mocha VNC (6,99 €).
Connect your iPad via Wi-Fi to the "ad-hoc" network of your PC, or connect the PC and iPad to the Wi-Fi access point, then launch Mocha VNC Lite. Enter parameters in the application settings as below, clicking " Configure > New ", once completed click " « Connect ".
The’IP address is that your server TightVNC. The port is 5900 default mode. The password is, obviously, that you typed in the TightVNC settings.
What is the interest ?
If you are using an app such as Time Zero, Adrena, or ScanNav on your PC, this technique offers a simple method to control it (partially) and view the screen of your PC from iPad. VNC connection lets you use the iPad as active repeater, at the helm, while the watch or under deck-house.
The lower keys VNC Lite allows to reveal the keyboard input, setting menu, and control the display full-screen PC controlled. Taps his finger on the touch screen to guide the mouse scroll, open the menus, activate the icons on the toolbar, etc. The control is sketchy, but enough for a remote screen repeater.
