Before, also encountered such a problem, let me tangled up long time. Finally the solution was finally tried out.We downloaded sub-folders under the Sqljdbc4.0 folder in JDBC 4.0 CHS with two jar files, Sqljdbc.jar and Sqljdbc4.jar. We follow the online blog, when the configuration to establish the data connection, add is Sqljdbc.jar this jar file, so there will be such a problem. Instead, you should add Sqljdbc4.jar. That would not have been the case.This d
Mysql is a non-persistent connection function, while mysqli is a permanent connection function. That is to say, mysql will open a connection process each time it connects, and mysqli will use the same connection process to run mysqli multiple times, thus reducing the overhead of the server. Some differences between mysql and mysqli found on the Internet:
Mysql is a non-persistent connection function, while mysqli is a permanent connection function. That is to say

Some differences between mysql and mysqli found on the Internet:Mysql is a non-persistent connection function, while mysqli is a permanent connection function. That is to sayMysql opens a connection process at each link, and mysqli runs mysqli multiple times to use the same connection process, thus reducing the server overhead.Recently, the website has been plagued by the problem of full occupation of processes due to the increase in access traffic. Therefore, to reduce the process overhead, a s

According to the driver provided by sonix, You need to configure it in the kernel to add it to the kernel or compile it with the module:
1. Add the driver folder to The makefile and try to keep it consistent with the original folder,
OBJ-$ (config_usb_sn9c102) + = sn9c102/OBJ-$ (config_usb_sonix_uvc_sn9c29x) + = sonix_uvc_sn9c291/OBJ-$ (config_usb_et61x251) + = et61x2

According to the driver provided by sonix, You need to configure it in the kernel to add it to the kernel or compile it with the module:
1. Add the driver directory to The makefile to keep it consistent with the original directory,

2. Add the src directory in kconfig
Now I am looking at the device driver while studying the kernel. Here is our real-time clock, which I understand.
1. m41t81 communicates with PXA270 through I2C bus;
2. the I2C driver is very important, including the initialization, reading, and writing of the I2C bus;
3. Various I2C controllers control initialization, read and write operations. Therefore, we need to clarify the mechanisms of each contro
Some students found that the CPU does not support virtualization when installing the virtual environment with the book CD, so I made a virtual environment that does not require virtualization, using virtual box, UBUNTU linux10.04 lts (around 4 GB)
You can download and use it if necessary. This virtual environment contains the lab environment required in the book (except for AndroidSource code, Too big, you need to write it yourself, otherwise it will

To install a driver under Windows, we need to pack all the software you need-called a driver package. The driver package includes the general installation tools provided by the system for all device classes, and includes device-specific components provided by the device vendor. Let's take a look at what components are specifically needed in the
