Windows Driver structure:

What I want to talk about is that the structure of the windows Driver is the same as that of the C ++ program. After you know this, you will feel much simpler.

First, make some necessary preprocessing in a header file; then define the device extension struct (equivalent to Class) that will be used; then, declare the function. After all this is done, we will implement these functions in the. cpp file, but let's talk about them differently:

1. the struct declared here is used to store device information;

2. The declared function is outside the struct. To be compatible with C, use the extern "c ";

3. declared functions are generally divided into three parts: function entry (equivalent to the main function), device creation function, and device uninstallation.

Next let's take a look at the examples in the author's book: (Note: the last few lines are added after two examples from the author by iker)

#030 UNICODE_STRING ustrSymLinkName; // Symbolic Link name
#031} DEVICE_EXTENSION, * PDEVICE_EXTENSION;
#032
#033 // function declaration
#034
#035 NTSTATUS CreateDevice (IN PDRIVER_OBJECT pDriverObject); // here is the function for creating a device #036 VOID HelloDDKUnload (IN PDRIVER_OBJECT pDriverObject); // here is
Declare a function to uninstall the driver.
#037 NTSTATUS HelloDDKDispatchRoutine (IN PDEVICE_OBJECT p1_bj,
#038 in pirp pIrp); // declare a default dispatch function.
#039

#040   extern "C"
#041   NTSTATUS DriverEntry(IN PDRIVER_OBJECT DriverObject,
#042                        IN PUNICODE_STRING RegistryPath);

// Here is the entry to define the function, which is equivalent to the main function

The next step is to implement these functions in the. cpp file. You should be clear about them and will not go into details!

Windows driver development technology details

Windows cannot load the device driver of this hardware. The driver can be corrupted or lost (code 39)

Start-run-regedit-go to the Registry and go to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Class \ {4D36E965-E325-11CE-BFC1-08002BE10318} to delete the upperfilters item and loweverfilters item

You can use either of the following methods: 1. Go to the control panel and select "Add new hardware". Then, follow the prompts to proceed step by step. After the system check is complete, you can generally find the optical drive; 2. Go to the control panel, select "Device Manager", delete the "hard disk controller" item, and restart the computer. Because the optical drive and the hard drive use the same controller, when it is deleted and restarted, it will be automatically identified, and generally the drive letter of the optical drive can be retrieved.

Windows can successfully install the device driver software, but the driver software encountered a problem when trying to run the code is 39

Don't panic, I have encountered this problem just now, and it has been solved. The specific steps are as follows:
1. Put the drive CD you sent when buying a computer and re-install it. If the drive is unavailable, download it from the official website of the laptop manufacturer. The burner driver and the driver of the motherboard are required.
2. After the driver is installed, step 2 is to right-click the properties of the computer, open the Device Manager, say hello to the hardware to be updated, and select Update driver software, then, browse the computer to find the driver, select the "C: \ WINDOWS \ WINSXS" path, and click Next. If a prompt is displayed that the compatibility problem is skipped, select Continue. Generally, you can click here,
3. If the installation fails, repeat the second time and select C: \ WINDOWS \ SYSTEM32 \ DRIVERSTORE \ FILEREPOSITORY.
