Eugen Graf Posted June 15, 2007 Report Share Posted June 15, 2007 Have anybody work with WDM ? It's possible to create a driver for capturing video devices and use this in LV? My collegue created an ActiveX (ocx) with Borland C++ and I use it succesfully in LV, but I want to create my own driver without using ActiveX. Any infos? Thanks, Eugen Quote Link to comment

I haven't exactly done this but it is not impossible. A WDM driver is however a driver that uses an object oriented architecture. Not something you could directly access in LabVIEW. Also a WDM driver runs in the context of the Windows kernel. What this all means is you will have to write a user space DLL, that does access the WDM driver and provides a standard C API to be called by LabVIEW. Rolf Kalbermatter Quote Link to comment
