The BS System Using C # + ODBC has no problem in vs2005, but it will appear after it is released"Error [im002] [Microsoft] [ODBC driverProgramManager] No data source name found and default driver not specified"Error, the problem is that the type created by DSN is incorrect. In "ODBC data source Manager", you can set three DSN types for connecting to the database: User DSN, system DSN, and file DSN. IIS is a system-level NT Service. Therefore, you ca

I. Some preliminary knowledge 1. You have been able to write led bare-board drivers.Program 2. convert a physical address to a virtual address In the program, we can only use the converted virtual base address and register offset to access the corresponding register, instead of directly accessing the physical register as the bare board program, so the physical address must be converted, the following is an example. # Include Void _ iomem * vir_base; vir_base = ioremap (gpio_base, gp

To reinstall ODBC, follow these steps: Use odbcconf.exe to re-register the ODBC driver. There are several script files in the Windows/system32 directory to complete the driverProgramRegistration: Odbcconf.exe/S/LV odbcconf. log/F % SystemRoot % \ system32 \ mdaccore. RSPOdbcconf.exe/S/LV odbcconf. log/F % SystemRoot % \ system32 \ sqlclnt. RSPOdbcconf.exe/S/LV odbcconf. log/F % SystemRoot % \ system32 \ odbcconf. RSPOdbcconf.exe/S/LV odbcconf. log/

At the end of the norflash driver load, there are several statements: If (ezkit561_mtd) {ezkit561_mtd-> owner = this_module; return handler (ezkit561_mtd, ezkit561_parts, ezkit561_part_count );} use add_mtd_partitions (Drivers/MTD/mtdpart. c) The function can add corresponding partitions to the partition table of the system. In this way, when you need to read and write the partitions, you can find the corresponding MTD and call its function to complet

Call other driver functions in the driver (fastcall) Author: Lai yuping (auly) aulyp@163.com In embedded systems, some communication ports are public, such as IIC ports and serial ports. Drivers of these ports are usually written by the OEM manufacturer and tested, relatively stable. We do not need to write an IIC driver when developing drivers for other devices

This kind of driver mainly presents streaming function interfaces, including XXX_Init, XXX_Deinit, XXX_Open, XXX_Close, XXX_Read, XXX_Write, XXX_Seek, XXX_IOControl, XXX_PowerUp, XXX_PowerDown, etc, note that the preceding interfaces must be output, and XXX must contain three characters. Otherwise, an error occurs. You can manually call the RegisterDevice () and DeregisterDevice () functions to load and uninstall the

Kernel 2.6.29.4 USB devices are actually complicated, but the Linux Kernel provides a subsystem called USB core to handle most of the complicated work. Therefore, the interface between the driver and USB core is described here.In the USB device organization structure, there are four layers: device, config, interface, and endpoint.A brief description of these four layers is as follows:A device usually has one or more configurations.Configuration often

During hardware power-on initialization, the BIOS checks all PCI devices and assigns a physical address to each device. The address is obtained and written to the configuration space of the device through the bios, And the CPU cannot be accessed directly, the driver can map this configuration space to common memory through ioremap for CPU access. When the operating system is initialized, each PCI device is assigned a pci_dev structure and the previous

After explaining the framework of the dm9000 NIC Driver in the first blog in this series, we should analyze this "giant thing" for beginners by module. This article first explains the. Driver and.

Before we loaded the driver is the use of instdrv this application, the principle is to write the corresponding fields in the registry, this section we manually write code to load the driver, the principle is similar:The dynamic loading of a device driver is primarily done by the Service Control Manager (MANAGER,SCM) system component .

1. What is Framebuffer?(1) framebuffer frame buffer (one screen data) (FB) is a virtual device in the Linux kernel, Framebuffer provides a unified standard interface display device to the application layer. Frame buffer (framebuffer)is an interface provided by Linux for display devices, a device that abstracts the graphics memory, allowing the upper-level application to read and write directly to the display buffer in graphical mode. This operation is abstract and uniform. UseYou don't have to w
