Communicating with CD DVD devices - port driver ? class driver ? I have an application that reads & writes to CD & DVD devices. I've not written my own device driver and have no ambitions to do so but I thought I'd ask a question here about something that still confuses me. The MS documentation for how to communicate with CD & DVD devices says the CD/DVD class driver is cdrom.... 7 Jan 2010 20:21
ndislwf monitoring filter preventing network connectivity Hi, I've modified the ndislwf to be a monitoring filter that binds below at the native 802.11 layer (below native wifi) at the "custom" level in Windows Vista. The sample works great, but the problem is whenever I install the driver it prevents network connectivity. I'm NOT putting it into monitor mode or some... 2 Feb 2010 17:26
Need help with Network Packet filtering (IDS) Hi, I need a network packet filtering SDK for Windows using which I'd be able to sniff packets over the network and block them after inspection. I need this for an Intrusion Detection system I'm planning to develop. The SDK should provide me with APIs (no matter user mode or kernel mode) to read incoming packet... 6 Jan 2010 12:01

Diplay driver architecture - Direct3D, OpenGL or both? Hi, My requirement is to write a generic display driver (using Windows Vista Display Driver Model) for Vista and Win 7. I understand that I need to write a user mode display driver and a miniport driver. The display driver will be bound to Direct3D runtime. My confusion comes from the point that WDK docs show ... 8 Jan 2010 01:47
Deadlock problem with ERESOURCEs in filesystem driver Hi, I am working on a Windows filesystem driver and I'm seeing a deadlock problem with 2 ERESOURCES. I have an ERESOURCE field for each Volume Control Block (VCB) that I use in the driver and another one for each File Control Block (FCB). In my testing there is only one VCB and multiple FCBs since I use a s... 6 Jan 2010 09:47
Updating UMDF drivers during development Hi, I am having some trouble updating UMDF drivers using "devcon" during a standard code-deploy-debug cycle. The problem is that "devcon update" isn't really updating anything unless the version number or the date of the DLL file and the INF file has changed from what is stored in the system's driver cache ... 9 Jan 2010 22:54
UMDF can not pass a stucture with pointers? Oops, there is a typo in my previous post, the correct DeviceIoControl code should be: DeviceIoControl((HANDLE) handle, IOCTL_VENDOR_REQUEST_EX, (LPVOID) vr, // Ptr to InBuffer dwInSize, // Length of InBuffer NULL, // Ptr to OutBuffer 0... 6 Jan 2010 09:47

Battery data is relayed to the computer through a custom board which connects to the windows computer using a USB connection. The battery driver needs to display battery status and shut down the computer when the bat... 29 Dec 2009 16:24 |
