问题 I am working on a script that will utilize the built in capabilities of Windows to unzip a supplied .zip file. I am pretty new to vbscript so some of the syntax stumps me a little. I am working with some existing code and trying to modify it so that it will take a command line option for the file name. If I use the command line to pass the file name, I receive the error: object required: 'objshell.NameSpace(...)' If I populate the same variable with text within the script, the script runs

Where to store large application data on android devices?

自闭症网瘾萝莉.ら 提交于 2020-01-13 09:17:27
问题 I'm currently facing a problem where I should store my object structure on the android device. The usecase: I'm starting a call to an applicationserver (with the great help of AsyncTask), get a well known response (xml-response) from the server, parse the data and transform it finally into my object structure (highly complex class diagram with many associations between the classes). So far it's working, thanks to the great XMLPullParser ;) I'm wondering where to store (and of course share)

Using object as key in dictionary in Python - Hash function

落爺英雄遲暮 提交于 2020-01-13 09:12:09
问题 I am trying to use an object as the key value to a dictionary in Python. I follow the recommendations from some other posts that we need to implement 2 functions: hash and eq And with that, I am expecting the following to work but it didn't. class Test: def __init__(self, name): self.name = name def __hash__(self): return hash(str(self.name)) def __eq__(self, other): return str(self.name) == str(other,name) def TestMethod(): test_Dict = {} obj = Test('abc') test_Dict[obj] = obj print "%s" %

java学习:用反射构造bean

假如想象 提交于 2020-01-13 08:31:48
先贴一些反射的基本知识: -------------------------------------------------------------------- 一、什么是反射: 反射的概念是由Smith在1982年首次提出的,主要是指程序可以访问、检测和修改它本身状态或行为的一种能力。这一概念的提 出很快引发了计算机科学领域关于应用反射性的研究。它首先被程序语言的设计领域所采用,并在Lisp和面向对象方面取得了成绩。其中 LEAD/LEAD++ 、OpenC++ 、MetaXa和OpenJava等就是基于反射机制的语言。最近,反射机制也被应用到了视窗系统、操作系统和文件系统中。 反射本身并不 是一个新概念,尽管计算机科学赋予了反射概念新的含义。在计算机科学领域,反射是指一类应用,它们能够自描述和自控制。也就是说,这类应用通过采用某种机 制来实现对自己行为的描述(self-representation)和监测(examination),并能根据自身行为的状态和结果,调整或修改应用 所描述行为的状态和相关的语义。 二、什么是Java中的类反射: Reflection 是 Java 程序开发语言的特征之一,它允许运行中的 Java 程序对自身进行检查,或者说“自审”,并能直接操作程序的内部属性和方法。Java 的这一能力在实际应用中用得不是很多

how to build arrays of objects in PHP without specifying an index number?

。_饼干妹妹 提交于 2020-01-13 07:47:06
问题 Here is a weird question. I am building an array of objects manually, like this: $pages_array[0]->slug = "index"; $pages_array[0]->title = "Site Index"; $pages_array[0]->template = "interior"; $pages_array[1]->slug = "a"; $pages_array[1]->title = "100% Wide (Layout A)"; $pages_array[1]->template = "interior"; $pages_array[2]->slug = "homepage"; $pages_array[2]->title = "Homepage"; $pages_array[2]->template = "homepage"; I like how clearcut this is, but because I have to specify the index

Do object references take up extra memory?

ぃ、小莉子 提交于 2020-01-13 07:27:07
问题 Lets say you have the following complex object: var object1 = .... // (something complexed) This takes up x amount of memory in your JS application. Now lets say you have some other objects that reference object1 : var otherObject = { something: true, value: 'yes', object: object1 }; var anotherObject = { color: '#FFF', object: object1 }; Have I tripled the amount of memory that object1 originally took up? Or do the references to object1 not add to the overhead of the memory used? I'm not

FabricJS image object clipTo shape object issue
