解决Delphi的SOAP Header问题

Until persistence is added all changes to objects in the EcoSpace will be lost when the application terminates. Prolonging the<br>life of these objects beyond the life of the application is a very simple process. By adding an ECO persistence component to<br>the EcoSpace it is possible to update a persistence storage with changes made during the application's execution, this<br>persistence storage might be a local XML file, a number of supported database servers, or a custom persistence mechanism<br>to work with persistence storages that are not supported by default.<br><br>Summary<br>Making an EcoSpace persistent is a very simple process. As a consequence switching to a new database can be achieved<br>in seconds. It is also possible with a small amount of programming to identify which type of database server to connect to at<br>runtime, allowing your application to connect to the database of your customer's choice.<br>Database structure management<br>ECO is not only capable of creating your database structure, but also updating the database structure to reflect changes<br>made to your business model. Automatic database structure management saves the developer a considerable amount of<br>time when creating applications.<br>Supported databases<br>At the time of writing the following databases are supported by ECO.<br>• BlackFish.<br>• DB2 (via Delphi BDP or DBX components).<br>• InterBase (via Delphi BDP or DBX components).<br>• FireBird 2.<br>• MySQL.<br>• Oracle.<br>• SQL Server.<br>• Sybase (via Delphi BDP or DBX components).<br>• XML file.<br>More advanced persistence techniques such as mapping to an existing database, reverse engineering an existing database,<br>and using a remote persistence server will be covered in a subsequent document.

镍氢、镍镉充电控制专用IC MC33340-D资料The MC33340 and MC33342 are monolithic control IC’s that arespecifically designed as fast charge controllers for Nickel Cadmium(NiCd) and Nickel Metal Hydride (NiMH) batteries. These devicesfeature negative slope voltage detection as the primary means for fastcharge termination. Accurate detection is ensured by an output thatmomentarily interrupts the charge current for precise voltagesampling. An additional secondary backup termination method can beselected that consists of either a programmable time or temperaturelimit. Protective features include battery over and undervoltagedetection, latched over temperature detection, and power supply inputundervoltage lockout with hysteresis. Fast charge holdoff time is theonly difference between the MC33340 and the MC33342. TheMC33340 has a typical holdoff time of 177 seconds and the MC33342has a typical holdoff time of 708 seconds.• Negative Slope Voltage Detection with 4.0 mV Sensitivity• Accurate Zero Current Battery Voltage Sensing• High Noise Immunity with Synchronous VFC/Logic• Programmable 1 to 4 Hour Fast Charge Time Limit• Programmable Over/Under Temperature Detection• Battery Over and Undervoltage Fast Charge Protection• Power Supply Input Undervoltage Lockout with Hysteresis• Operating Voltage Range of 3.25 V to 18 V• 177 seconds Fast Change Hold–off Time (MC33340)• 708 seconds Fast Change Hold–off Time (MC33342)
