Access Data Project (ADP) - Access 2007 or 2003?

阅读更多关于 Access Data Project (ADP) - Access 2007 or 2003?

问题 I have been tasked with writing an ADP application using Access. The back-end data will be stored in SQL Server. We have SQL Server 2000, 2005, and 2008 available to us. Requirements dictate that Access must be used but I may have a choice of using Access 2003 or Access 2007. My first thought was to push for Access 2007, because it was newer and we could use SQL Server 2005 or perhaps 2008, however, when searching the web for Access 2007 and ADP I find a lot of posts from people saying the

问题 Access 2013 does not support ADP. Some alternatives to ADPs are given: Convert the ADP to a linked Access Desktop Database. Import objects into an ACCDE file and then create linked tables to the existing data by using an earlier version of Access. My ADP contains only Forms, Reports, Macros and Modules. I want to use this ADP in Access 2013 (not on any earlier version of Access). I have not found any method to convert ADP to a linked Access Desktop Database or to Import objects into an ACCDE

PNP晶体管：特性和应用

阅读更多关于 PNP晶体管：特性和应用

　　您可能很清楚，现代电气工程，实际上是整个现代世界，与称为晶体管的设备密不可分。这些组件既可用作开/关开关，也可用作放大器。虽然场效应晶体管目前在电子领域占主导地位，但原始晶体管是双极晶体管，很快就会有第一个双极结型晶体管或BJT。　　BJT有两种基本形式：NPN和PNP。这些字母指的是正掺杂半导体层和负掺杂半导体层的排列，如下图所示：　　请注意，彩色PNP和NPN图是简化的，不能反映集成电路BJT的实际物理配置。　　NPN与PNP：为什么PNP晶体管很重要　　根据我的经验，NPN晶体管比PNP花费更多时间。想到这一点的几个原因：　　NPN晶体管的电压和电流特性（至少在我看来）更加直观。　　当需要开关或驱动电路时，NPN为数字输出信号（例如微控制器产生的控制信号）提供了更直接的接口。　　NPN实际上在重要方面优于PNP。这导致了NPN的特别主导地位，因为BJT必须与MOSFET竞争，BJT团队在向比赛发送NPN时更容易获胜。笔者这个2009年加州大学伯克利分校的文件，胡正明，走得更远，他说的，因为这种情况，即较高的NPN性能和MOSFET的-BJT的普遍倾向于认为是“几乎完全是NPN型的。” 　　因此，我们不能否认PNP不太常见，并且通常不太理想 - 但这并不意味着我们应该忽略它们。本文的其余部分将讨论PNP特性和应用程序。　　电荷载体：电子与空穴　　如上所示
