问题 Alright, I'm not sure if I'm asking the right question, but here goes. I'm using Javascript .NET to parse a Javascript object array. My code looks something like this: object packlist; using (var context = new JavascriptContext()) { context.Run(@"function packlist() { this.packs = new Array(); } var packlist = new packlist(); packlist.packs[0] = { item1:""something"", item2:""something2"", item3:""something3"" }; packlist.packs[1] = { item1:""something"", item2:""something2"", item3:"

vba simple range/object error

阅读更多关于 vba simple range/object error

问题 So I thought I had an OK grasp of VBA but now this error is really bugging me and I can't figure out the problem. Here is an incredibly short subroutine (run from a module): Sub test() Dim lr lr = Sheets(1).Range("a1", Cells(65, 1)) MsgBox lr.Address End Sub For whatever reason this throws up an "application defined/object defined error" can anyone explain? Edit: This also throws up the same error: MsgBox Sheets(1).Range("a1", Cells(65, 1)).Address Edit2: I'm going to change my question a bit

Where is the Excel Object Library file

阅读更多关于 Where is the Excel Object Library file

问题 I'm looking for the Excel Object Library file to import it into LabVIEW. I have MS Office 2013 installed and can find MSACC.olb, MSOUTL.olb, MSPPT.olb, and MSWORD.olb but can't figure out which file (.olb or .dll) to import in order to manipulate Excel files in LabVIEW. 回答1: The Excel team does it differently. The Excel object library is the executable: Office 2013: C:\Program Files (x86)\Microsoft Office\Office15\EXCEL.EXE Office 2016: C:\Program Files (x86)\Microsoft Office\root\Office16

Passing a C++ object with an Objective-C (Cocoa) event (performSelector)

阅读更多关于 Passing a C++ object with an Objective-C (Cocoa) event (performSelector)

问题 How to pass a C++ object with the performSelector method? This method only allows you to pass 'objc_object*' objects, I can't cast them. I could build a wrapper, but I don't know the overall superclass for all C++ objects, so I don't know how I could build a generic wrapper (I don't want specific knowledge about the object in the wrapper).. Any hints? 回答1: Try just using +[NSValue valueWithPointer:]. 来源： https://stackoverflow.com/questions/1928152/passing-a-c-object-with-an-objective-c-cocoa

Spring AspectJ 一、基于注解的方式配置通知 1、额外引入的jar包：　　a) com.springsource.org.aopalliance-1.0.0.jar 　　b) com.springsource.org.aspectj.weaver-1.6.8.RELEASE.jar 　　c) spring-aop-4.0.0.RELEASE.jar 　　d) spring-aspects-4.0.0.RELEASE.jar 2、在xml中加入aop 的命名空间　　xmlns:aop="http://www.springframework.org/schema/aop" 　　//自动为匹配的类生成代理对象　　<aop:aspectj-autoproxy></aop:aspectj-autoproxy> 3、把横切关注点的代码抽象到切面的类中　　a) 切面首先是一个 IOC 的bean,即加入@Component 注解　　b) 切面还需要加入@Aspect 4、在类中声明各种通知　　a) @before 前置通知在方法执行之前执行　　　　a.i) AspectJ 表达式： @Before("execution(*1 com.spring.springaop.*2.*3(...))") //*1 代表所有类型的返回值；*2 代表所有的类；*3

一 .AOP [ 知识点详解 ] AOP:中文名称面向切面编程英文名称:(Aspect Oriented Programming) 正常程序执行流程都是纵向执行流程 3.1 又叫面向切面编程,在原有纵向执行流程中添加横切面 3.2 不需要修改原有程序代码 3.2.1 高扩展性 3.2.2 原有功能相当于释放了部分逻辑.让职责更加明确. 面向切面编程是什么? 4.1 在程序原有纵向执行流程中,针对某一个或某一些方法添加通知,形成横切面过程就叫做面向切面编程. 常用概念 5.1 原有功能: 切点, pointcut 5.2 前置通知: 在切点之前执行的功能. before advice 5.3 后置通知: 在切点之后执行的功能, after advice 5.4 如果切点执行过程中出现异常,会触发异常通知.throws advice 5.5 所有功能总称叫做切面. 5.6 织入: 把切面嵌入到原有功能的过程叫做织入 5.6.1 spring 提供了 2 种AOP 实现方式 5.6.2 Schema-based 5.6.3 每个通知都需要实现接口或类 5.6.4 配置spring 配置文件时在<aop:config>配置 5.6.5 AspectJ 5.6.6 每个通知不需要实现接口或类 5.6.7 配置spring 配置文件是在<aop:config>的子标签 ,<aop

问题 I'm having issues creating a copy of an object array. I can't get the new reference to point to a new independent array. function OBJ1(name, tags) { this.myname = name; this.mytags = tags; this.myvalue = 0; } function OBJ2(arg1) { this.arg1 = arg1; this.myarray = []; } var OBJ1_array = []; var result_array2 = null; var result; OBJ1_array = createarray1(); for (i = 0; i < 2; i++) { result = createarray2(); } function createarray1() { var myarray = []; myarray.push(new OBJ1("NAME", [1, 2, 3]));
