Hi All, I am trying to develop a tool that would allow the user to switch between two different glideslopes at a certain airport i', developing, i wasnted the tool, depending on what the user selects to install the correct .bgl file into the scenery folder, is that possible ? If so, is there any tutorials anyway that say about creating this kind of code, this is what i have so far, using Microsoft Visual 2008 to do so. The graphical interface is shaping up, ish. The idea would be that the user selects the scenery folder where the .bgls are kept, and the addon scenery/scenery folder where the .bgl would be moved, they then select the glideslope that they wanted, and the relevant .bgl would be installed. Any thoughts please ?
