Through object-oriented encapsulation, it is easy to implement a spin lock object. Lock () is the code for entering the Zone, and unlock () is the code for exiting the zone. You can design your own details, this is not much to be said here.

【Abstract】 3]Use include columns to avoid size restrictions
You can include non-key columns in a non-clustered index to avoid exceeding the current index size limit (the maximum number of key columns is
16. The maximum index key size is
900 bytes ). The Database Engine calculates the number of index key columns or index key size hours, regardless of Non-key columns.
For example, if you want to create an index for the following columns in the Document Table of the adventureworks sample databas

the light source does not affect the relative propagation speed of the light, it affects the frequency. That is to say, due to spectrum migration, electromagnetic waves that are invisible at a constant rate may be seen during actual motion! This is a key point. If you are moving forward at an approximate speed of light, even though a pile of photon occurs on the face, you are "receiving" the light, but in fact because of its infinite frequency, you can't really perceive it, so you are in front

Is it because the logo of eclipse is too tired? If you change to your favorite photo, you will feel a lot better. Here we will teach you how to replace it. I know there are two ways.
Before introducing the two methods, there was a basic problem, that is, what conditions are required for your image as a logo?
In fact, the condition is very simple. Open your image and save it in BMP format and name it splash. But if so, the width of the progress bar when eclipse is started does not match your pi

protocol.3. In WindowsNT, SMB is implemented based on NBT, that is, port 139 (TCP) is used. In Windows2000, SMB is implemented based on NBT and port 445.
With these basic knowledge, we can further discuss the port selection for access network sharing:
For the Win2000 client (initiator:1. If NBT is allowed to connect to the server, the client tries to access ports 139 and 445 at the same time. If port 445 has a response, the client sends an RST packet to port 139 to disconnect, when port
