VC中动态打开数据库的实现-VC dynamic database opened the realization

INDUCTION MOTOR RUN (Currents and speed as state variables) The motor is running at a specified load. After reaching steady state in an initialization first run, the initial conditions are established for a second run in which the load is pulsating. The dynamic equations are expressed in canonical first-order matrix form adopting currents and speed as state variables, and are solved using ODE45. The user has the choice of selecting one of three common (dq) reference frames: STATOR, ROTOR or SYNCHRONOUS. The torque, speed,and current responses are plotted. -INDUCTION MOTOR RUN (Currents and speed as state variables) The motor is running at a specified load.

二进制文件保存，提取 使用stream 完成，解压后建立数据库，将image设为二进制-binary files kept from the use of stream completed, unpacked databases, image will be set to binary

Adding ODBC support to a new application使你的程序添加ODBC支持-Adding ODBC support to a new application allows you to add the procedures to support ODBC

这也是采用COM接口的数据库访问技术， 采用ADO类封装，速度快，更加容易调用。- This also is uses the COM connection the database visit technology, uses a ADO kind of seal, the speed quickly, is easier to transfer.
