问题 I just bought a new keyboard, and I'm interested in tracking exactly how many keypresses/strokes I make during the entire life of the keyboard. (I would want to just record keyUp, as I don't care about repeats) I've been googling around for the best way to do this, but I don't even know what approach to take, so I'm having trouble searching intelligently. Also, the only language I've really worked with is C#. Haven't done anything with C/C++ or WinAPI Is it difficult to modify the Win 7

问题 I have a really short question: Is it possible to communicate/use USB devices on Android OS? I assume it might be tablet device. Lest say i want to connect some sort of USB card scanner to android tablet. Will it work? Do i need to write drivers by myself? Thanks. 回答1: First, you need a USB host port on your tablet. Except for On-the-Go (which is a special design that can be either host or device), it is not possible to connect two USB devices together. The incompatibility is electrical, no

问题 everybody, I have the following problem: I started a P2 instance with this AMI. I installed some tools like screen, torch, etc. Then I successfully run some experiments using GPU and I created an image of the instance, so that I can terminate it and run it again later. Later I started a new instance from the AMI I created before. Everything looked fine - screen, torch, my experiments were present on the system, but I couldn't run the same experiments as before: NVIDIA-SMI has failed because

问题 I want to create a software which windows will detect it as a installed printer driver and list that software under "Devices and Printers" Just like the ImagePrinter sowftware, you can access it through following link. http://sourceforge.net/projects/imageprinter/ when this Image Printer is installed on a computer, windows lists it under Printers and Devices so we can right click and share it in our network. LAN users can add this as a remote printer and send print jobs to it, which it will

问题 I'm looking for writing virtual camera drivers. Does anybody has idea? Any book that would be helpful or any link. Adding more details: I have developed a device driver which saves the image to disk and the display uses the device driver to display the image. The performance does not seem good. The fns. that I have used are: //to capture GetDesktopWindow() CreateCompatibleBitmap() Save() //to display WM_MOUSEMOVE giving a call to capture and display every time but the display is not

问题 I want to know the difference between FIQ and IRQ interrupt system in any microprocessor, e.g: ARM926EJ. 回答1: A feature of modern ARM CPUs (and some others). From the patent: A method of performing a fast interrupt in a digital data processor having the capability of handling more than one interrupt is provided. When a fast interrupt request is received a flag is set and the program counter and condition code registers are stored on a stack. At the end of the interrupt servicing routine the

问题 Does anyone know how do I connect to MongoDB via SQL Developer? I Have tried to install the third Party JDBC Drivers in SQL Developer for MongoDB but after restarting the SQL Developer I cannot see any options available. Thanks in advance, Vassilis 回答1: Sorry, MongoDB is not a supported migration platform, so we do not support connections to it. We offer connections to 3rd party databases to allow for migrations to Oracle Database. It's not designed to be a poly-DBMS IDE/GUI. 来源： https:/

问题 I have a network device where a port of an Ethernet switch chip is connected to a CPU's network controller. The switch chip forwards packets from other ports to the CPU port with special header added (before MAC header) containing such information as ingress port etc. I can strip the header when receiving the packets in the network controller driver, so the Linux network stack can communicate with the switch in a normal way. My goal, however, is to pass some information in the special headers
