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.

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

1. Framework object model2. kmdf program structure Kmdf is a plug-and-play driver model: 1. A DriverEntry routine. 2. An evtdriverdeviceadd routine, similar to the adddevice routine of WDM. 3. One or more Io queues. 4. A callback routine for multiple active Io events is similar to the dispatchxxx of WDM. 5. plug-and-play and power management callback routines are supported. 6. Supported WMI callback routines for managing computer systems 7. Other call

Developers need to log on to the function, so they do not want to use a large database and directly use java to connect to access.

With the increasing of USB devices, development of USB driver is becoming more and more important in embedded development. Windows CE's support for USB 2.0 is a huge boost to this wave of new technologies. The author of this article analyzes his own use-driven development experience, hoping that readers can take less detours. With the increasing of USB devices, development of USB driver is becoming
