[QUOTE="mywaypeng, post: 209454"] HI Aaron. so pleased that you have get eyes on my problem. I'm so sorry to my porr enlish. We are developing IR tranceiver & remote control for Vista. now our RCU (Remote Control Unit) & Receiver can control Media Center correctly. It also use the driver provided by MS ( cirlass & usbcir ). our second step is to develop Tranceiver. but the problem of mine is that I should first read the data from the device in form of RLC. so that we learn IR code in other format ( eg. NEC-1). I have read the code "MCEIR.DLL" for xp mce 2005. and it's work for recording IR code(under XP). But I can't use it in vista....... when use win32 API to create a handle for the device , it alway return -1. I'm not sure the GUID for the driver "USBCIR". so I look up regedit . there are four potential: {064f8c82-77b2-445e-b85d-c4e20f942fe1} {00873fdf-61a8-11d1-aa5e-0c04fb1728b} {7951772d-cd50-49b7-b103-2baac494fc57}//this is IRBUS 's guid for xp {a5dcbf10-6530-11d2-901f-00c04fb951ed} DevicePath as :"\\?\usb#vid_XXXX&pid_XXXX#v10010#{7951772d-cd50-49b7-b103-2baac494fc57}"; I just want to know how to "createfile()" to open handle then read data from Device ( actual read from driver). thanks for attend. ----- Jack [/QUOTE]
