PROTEL Autotrax XP video driver
If you have a VESA bios equipped video card in your system, whether or not your system runs XP, we suggest you use as a first choice our VESA video drivers. The main shortcoming of the XP driver (compared with the VESA drivers) is that Autotrax, being a DOS application, does not redraw the screen when obscured by another application or minimized then restored. This means when you restore the Autotrax window it is Black until you press "End", or move, or zoom in and out, or do some other operation that cause Autotrax to specifically alter the screen. This is not actually a programming error on our part - it is just what happens when a DOS application is run in a window. XP normally runs these full screen. When you are using Autotrax and autoXPDv, and you wish to use the mouse, you must right click in the window title bar and select "Hide Mouse Pointer". The mouse then becomes exclusive to autotrax - to get control of the mouse back to windows again you must either alt-tab away from Autotrax, or quit the application (Esc - F - Q - Y)
This driver is hereby released into the public domain, and you can do what you like with it with no obligation. It was written by Steve Murray of AirBorn, and is open source. These drivers may well be updated, check back on this webpage, periodically, for new versions: www.airborn.com.au/layout/autoxpdv.html I would like to give credit to Mark Smit of Canada, for his work on implementing DirectX primitives, which we use in this code, and also to Japheth of Germany, for his advice on implementing VDM calls in 16 bit code. We also have a webpage up describing just how we went about connecting the 16 bit application to the 32 bit DLL, if you are interested in the technical side of the task. |
