Detecting whether a device driver is installed
Hi All,
I have an application that can run on various versions of Windows, i.e. 98, 2000, XP. Unfortunately, there are several device drivers that can be used by the application DLL. The first iteration used a COTS device driver to run on WIN98, but a dedicated driver was developed for WIN2K and XP. Unfortunately, it turns out that some legacy applications can use the earlier driver while running on XP, in which case the newer driver has not, and apparently WILL not, be installed. (They want to just plug in the upgraded hardware without changing any software at all.) I can rewrite our API to use either driver, but I am looking for a way to detect which driver has been installed. LoadLibrary will not work, because the new driver is a .SYS file. Is there a way to detect whether a .SYS file has been installed, other than doing a directory search? Thanks in advance, Leslie |
