I have been writing application software for the past few years. Because the environment does not meet special requirements, I started to understand the concept of a certain driver from Win95 to 99 years in 1997, it is an existence that does not dare to think about driving this thing. during previous development, a keyboard driver was needed, so I wanted to learn and develop a keyboard driver. first, we need to build a development environment. 1. windows XP 2. vs2008 3. winxp ddk 4. http://ddkwizard.assarbad.net/download ddkwizrd 5. run ddkbuild. CMD or ddkbuild. copy BAT to winddk "ver. For example, if my name is C:" winddk "3790.1830. add the C: "winddk to executable files in the VC directory environment of vs2008. Follow these steps. You can see the project with the DDK project when creating a new project. the package I uploaded is the first time I used the above environment to drive the Hello, world version based on others' methods and some source code.

Now that you have the environment and program, you need to test it on your computer. Secondly, the debugging environment of the driver. I strongly recommend that you use Vm and snapshot for testing. the following software is also required. 1. debugview to view debugging information 2. devicetree: view the device details of the driver. 3. osrloader is a very good tool for loading and starting drivers in real time. After debugging the above project, the source code has very clear comments. 1. the program will include driver1.sys 2 in driver1 "driver1" objchk_wnet_x86 "i386. upload the three tools mentioned above and driver1.sys to XP in VM 3. use osrloader to load the generated driver1.sys and start it. Then you can use devicetree to see the helloworld driver. I just said that I want to debug the environment. Why didn't I debug it? Don't worry. Here, it is because the helloworld driver won't be accessed and debugging information will naturally not be generated. In order to access helloworld, you need to develop another program to call the driver. Because there is only one file, it is a command line program, so the source code of the source author is released # define debugmsg # include <windows. h>
# Include <winioctl. h>
# Include <stdio. h> # define device_hello_index 0x860 # define start_hellpworld ctl_code (file_device_unknown, device_hello_index, method_buffered, file_any_access)

Let's take a look at the message printed in the driver using dbuplint in debugview.
Because it is familiar with driver development and has referenced others' source code, please forgive me.
