store

I originally posted this on the Sencha forums here but didn't get any responses (other than my own answer, which I will post soon), so I am going to repost it here and see if I get anymore help. I've been racking my brain on how to filter a TreeStore in 4.0.7. I've tried the following: The model Ext.define('model', { extend: 'Ext.data.Model', fields: [ {name: 'text', type: 'string'}, {name: 'leaf', type: 'bool'}, {name: 'expanded', type: 'bool'}, {name: 'id', type: 'string'} ], hasMany: {model: 'model', name: 'children'} }); The store Ext.define('myStore', { extend: 'Ext.data.TreeStore', model

Is SQL Server 2008 a good option to use as an image store for an e-commerce website? It would be used to store product images of various sizes and angles. A web server would output those images, reading the table by a clustered ID. The total image size would be around 10 GB, but will need to scale. I see a lot of benefits over using the file system, but I am worried that SQL server, not having an O(1) lookup, is not the best solution, given that the site has a lot of traffic. Would that even be a bottle-neck? What are some thoughts, or perhaps other options? 10 Gb is not quite a huge amount of

I have a problem concerning storing the output of a command inside a variable within a bash script. I know in general there are two ways to do this either foo=$(bar) # or foo=`bar` but for the Java version query, this doesn't seem to work. I did: version=$(java --version) This doesn't store the value inside the var. It even still prints it, which really shouldn't be the case. I also tried redirecting output to a file but this also fails. version=$(java -version 2>&1) The version param only takes one dash, and if you redirect stderr, which is, where the message is written to, you'll get the

I'm trying to compile a lua script that calls some exported functions, save the resulting bytecode to a file and then load this bytecode and execute it, but I haven't found any example on how to do this. Is there any example available on how to do this? How can I do this? Edit: I'm using Lua + Luabind (C++) This is all very simple. First, you load the Lua script without executing it. It does not matter if you have connected the Lua state with your exported functions; all you're doing is compiling the script file. You could use luaL_loadfile , which uses C-standard library functions to read a

I am doing a very small online store application in PHP. So I have an array of maps in PHP. I want to search for a string (a product) in the array. I looked at array_search in PHP and it seems that it only looks for exact match. Do you guys know a better way to do this functionality? Since this is a very small part of what I am actually doing, I was hoping that there was something built in. Any ideas? Thanks! EDIT: The array contains "products" in this format: [6] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 2000-YM ) [Name] => Team Swim School T-Shirt [size] => YM [price] =>

I want to store sample images. what is the best efficient way weather to store on SD card or in DB? if the images are not big(2-3 KB) and the collection of them is not supposed to be expanded then you can save them to db. But it would be harder to write them, read them. On the other hand the user won't be able to do anything with them. Otherwise, if you want to let user to expand the image collection or the images are rather big you should store them to sd card. Anyway, you should be aware of space lackness and treat those cases appropriately. 来源： https://stackoverflow.com/questions/4539130

This question already has an answer here: Handling passwords used for auth in source code 5 answers I'm developing an application which read some data from a db. The connection to the db is performed through standard login/password mechanism. The problem is: how to store the db password? If I store it as a class member, it can be easily retrieved through a decompiling operation. I think that obfuscation doesn't solve the problem, since a string password can be found easily also in obfuscated code . Anyone has suggestions? COD3BOY Never hard-code passwords into your code.
