data. For example, a 8-bit nor flash, assuming a capacity of 4 byte. The chip should have 8 data signals d7-d0 and 2 address signals, a1-a0. Address 0x0 corresponds to the No. 0 byte, the address 0x1 corresponds to 1BYTE, the address 0x2 corresponds to the 2nd byte, and the address 0x3 corresponds to the 3rd byte. To a 16-bit NOR flash chip, or working in 16-bit mode, an address corresponds to a half-word (16-bit) data. For example, a piece of 16-bit

Recently mentioned how a search engine can judge the originality of an article. We have heard that the more original content of the site, search engines will like, the site will be ranked more forward, so many editors comrades began to pull sleeves on his hips to make the original, but the time has passed, the site did not see the obvious effect, So there are a lot of people began to experience that the original content of the site on the search engine rankings have no effect, I reproduced the a
In group development, the application section uses DELPHI7, and some components are used in C + +. When you convert a C + + interface declaration header file for a dynamic library to a unit unit of D7 today, everything goes well until you encounter something else like this:typedef struct TAGRECORD{int Val;int Getvalplus (){val++;return Val;}}trecord, *precord;A struct with a function!

Multi-Criteria query in LINQ:
from S in data4Join D1 in Data_co on new {S.forecasttime,s.regioncode}
equals new {D1. Monidate, D1. Regioncode}But this only implements a join association, and an error occurs when there are multiple joins.
Modified as follows: Join D1 in Data_co on S.forecasttime equals D1. Monidatewhere S.REGIONCODE==D1. Regioncode
An association that implements multiple join multiple conditions
var data7 = (from S in data4Join D1 in Data_co on S.forecasttime equals D1. Monidate

First, you create a database file Db1.mdb with a blank password with accessxp, which contains a table with a field that doesn't have any data filled in. Save exit and then copy one for Db2.mdb, open 2.mdb exclusively, and add password 1324567890123 to save exit.
Use UltraEdit32 to open these two databases and compare them. The method I compare is also very simple. In UltraEdit32, quick and click on the tab of the open file (that is, switching
