• [C#] How to consume web service adheres to the Event-based Asynchronous Pattern?

  - by codemonkie

  I am following the example from http://msdn.microsoft.com/en-us/library/8wy069k1.aspx to consume a web service implemented (by 3rd party) using the Event-based Asynchronous Pattern. However, my program needs to do multiple calls to the DoStuffAsync() hence will get back as many DoStuffCompleted. I chose the overload which takes an extra parameter - Object userState to distinguish them. My first question is: Is it valid to cast a GUID to Object as below, where GUID is used to generate unique taskID? Object userState = Guid.NewGuid(); Secondly, do I need to spawn off a new thread for each DoStuffAsync() call, since I am calling it multiple times? Also, would be nice to have some online examples or tutorials on this subject. (I've been googling for it the whole day and didn't get much back) Many thanks

• Custom app.config section with a simple list of "add" elements

  - by Joe

  How do I create a custom app.config section that is just a simple list of add elements? I have found a few examples (e.g. http://stackoverflow.com/questions/1316058) for custom sections that look like this: <RegisterCompanies> <Companies> <Company name="Tata Motors" code="Tata"/> <Company name="Honda Motors" code="Honda"/> </Companies> </RegisterCompanies> But how do I avoid the extra collection element ("Companies") so that it looks the same as the appSettings and connectionStrings sections? In other words, I'd like: <registerCompanies> <add name="Tata Motors" code="Tata"/> <add name="Honda Motors" code="Honda"/> </registerCompanies>

• Disabling mouse movement and clicks altogether in c#

  - by ThaNerd

  At work, i'm a trainer. I'm setting up lessons to teach people how to "do stuff" without a mouse... Ever seen people click "login" textbox, type, take the mouse, click "password", type their password, then take the mouse again to click the "connect" button beneath ? So i'll teach them how to do all that without a mouse (among many other things, of course) At the end of the course, i'll make them pass a sort of exam. So i'm building a little wizard based app in which i present some simili-real-life examples of forms to fill in, but i want to disable their mouse programatically while they do this test. However, further in the wizard, i'll have to let them use their mouse again. Is there a -- possibly easy -- way to just disable the mouse for a while, and re-enable it later on? I'm on C# 2.0, programming under VC# 2k5, if that matters

• Grails multi column indexes

  - by Kimble

  Can someone explain how to define multi column indexes in Grails? The documentation is at best sparse. This for example does not seem to work at all: http://grails.org/GORM+Index+definitions I've had some luck with this, but the results seems random at best. Definitions that works in one domain class does not when applied to another (with different names of course). http://www.grails.org/doc/1.1/guide/single.html#5.5.2.6%20Database%20Indices Some working examples and explanations would be highly appreciated!

• Custom Data Types

  - by Tinkerer_CardTracker

  Hello, quick question: I'd like to create some custom data types, but I don't think I'm asking the right question(s). There are "compound Boolean" values used throughout .NET, and I want to design some of my own. I've been using a series of Boolean variables, which works, but just isn't the same. Examples from .NET include: Color.Black Alignment.Centered [fontProperties].Bold* *I forget the actual name, but you get the idea I want to make something like this: ColorSortQualities None DistinguishColor DistinguishNumberOfColors DistinguishColorPattern Once that's been declared, I could do this: if(searchOptions.ColorSortQualities == DistinguishColor) [do stuff] What is this called? Thanks!

• Bitwise Shifting in C

  - by user313943

  I've recently decided to undertake an SMS project for sending and receiving SMS though a mobile. The data is sent in PDU format - I am required to change ASCII characters to 7 bit GSM alphabet characters. To do this I've come across several examples, such as http://www.dreamfabric.com/sms/hello.html This example shows Rightmost bits of the second septet, being inserted into the first septect, to create an octect. Bitwise shifts do not cause this to happen, as will insert to the left, and << to the right. As I understand it, I need some kind of bitwise rotate to create this - can anyone tell me how to move bits from the right handside and insert them on the left? Thanks,

• View a SYS.XMLTYPE returned from an Oracle function, using PL/SQL

  - by caerphilly

  I have an Oracle function that dynamically creates an XML document, and returns it in a SYS.XMLTYPE value. I want to run a query from SQL Developer that calls that function and prints the document (either via a select, or dbms_output - I don't care). But all the examples/documentation seem to refer to querying XML columns in tables, and I can't seem to get the syntax right for my particular usage. I'd like something like this: declare x SYS.XMLTYPE; begin x := my_package.my_function(); select x.getclobval() from x; -- doesn't work! end; How can I print out the value of the XML type variable 'x' in the above code?

• Documenting a policy based design

  - by academicRobot

  I'm re-working some prototype code into a policy based design in C++, and I'm wondering what the best practice is for documenting the design. My current plan is to document: Policy hierarchy Overview of each policy Description of each type/value/function in each policy I was thinking of putting this into a doxygen module, but this looks like it will be a bit awkward since formatting will have to be done by hand without code to base the doc on (that is, documenting the policies rather than the implementation of the policies). So my questions are: Are there other aspects of the design that should be documented? Are there any tricks to doing this efficiently in doxygen? Is there a tool other than doxygen thats better suited to this? What are some examples of well documented policy based design? This is my first serious attempt at policy based design. I think I have a working grasp of the principles, but whatever naivety I expose in this question is fair game for an answer too.

• When and why will an OS initialise memory to 0xCD, 0xDD, etc. on malloc/free/new/delete?

  - by LeopardSkinPillBoxHat

  I know that the OS will sometimes initialise memory with certain patterns such as 0xCD and 0xDD. What I want to know is when and why this happens. When Is this specific to the compiler used? Do malloc/new and free/delete work in the same way with regard to this? Is it platform specific? Will it occur on other operating systems, such as Linux or VxWorks? Why My understanding is this only occurs in Win32 debug configuration, and it is used to detect memory overruns and to help the compiler catch exceptions. Can you give any practical examples as to how this initialisation is useful? I remember reading something (maybe in Code Complete 2) that it is good to initialise memory to a known pattern when allocating it, and certain patterns will trigger interrupts in Win32 which will result in exceptions showing in the debugger. How portable is this?

• Connecting Android XML and Code

  - by Nick

  I'm new to android and have gotten used to doing all my previous UI in code. I can understand the simple examples, but I'm trying something more complex and have no idea how to do it in code and XML. I'm trying to use the google map api and draw text on the map at a specified spot. I have succeeded in doing so by extending overlay and overriding the draw method using drawtext. This has pretty much accomplished what I'm looking to do, but I want have read that is poor practice. I now want to add a second line below the first and just using \n does not work. I can work it out using another drawtext method, but I figured it would be better to create a custom textview, I just have no idea how to position it using code and encapsulate it inside the overlay. Maybe the way I'm doing it is the best way...

• Using twitter gem to signup and authenticate users

  - by Jim Jones

  Hi, I'd like to allow users the option to register using their Twitter account. Basically, I'll present them with a standard signup form (name, login, email, pwd, pwd_confirm) as well as a "Signup with Twitter" link. If a user chooses to signup with Twitter creds, then I'll create a user record in db. Then I'd like to be able to allow a user to authenticate using their Twitter creds on returning visits. Also, I'm using restful_authentication, so I need to have this work within that context. What is the best way to do this? I haven't been to find any tutorials on allowing the signup and authentication pieces. Most examples just show how to authenticate a Twitter user into your app. Thanks.

• Xcode Tips for Eclipse users?

  - by willcodejavaforfood

  Hi, I've been slowly working my way through the examples in Beginning iPhone Development and there are a few things that I have not been able to figure out, but I'm sure you guys can help me with it. In Eclipse there is a Source-Generate Getters/Setters, can you do something similar to synthesize properties in Xcode I also cannot seem to find a Refactor menu I'm also struggling to find the equivalent to Source-Override/Implement Methods --Edit-- I failed to describe my problem it seems. I do know that synthesizing properties will generate getters/setters for me, but I am looking for a way to generate the @property/@synthesize code, by selecting the variables. Short list to start with, but I will probably have more as my confusion grows in might. :)

• Flex chart ItemRollOver behavior

  - by DannyC

  Hi Guys, I'm trying to prevent a default chart item roll over highlight in a Spark column chart. If you look at any of the chart examples on this page , when you roll over any of the chart series items, they turn a darkened shade of their original colour. This is what I want to prevent. So far I have had no luck with using the itemRollOverColor property, as this only allows you to set it to one specific colour for the whole chart (my app has several different coloured series on the chart at once). Also, trying to leverage the itemRollOver event (with preventDefault() etc) hasn't worked either. Does anyone have any idea what I am missing here? Thanks for reading guys

• How to tile a UIWebView?

  - by franky

  I need to use tiles with a UIWebview to improve the rendering and scrolling of the content. I tried to find some info in Google but it seems that there are no examples or technical info about this subject. I am doing some test with CATiledLayer class without luck... Basically, I want to replicate the same that Mobile Safari does with the content of a website. You can see how Safari makes tiles when you see the squared background. Any help will be very welcome! Thanks in advance, Franky

• Handling Data Hierarchies in code

  - by Miau

  Hi there So, say I have a string to parse with a given format that maps to a tree like data structure. The string is kinda similar to a folder path, and the structure is similar to a file structure, except its got some rules so for something@cat1@otherSomething you would get /something/cat1/otherSomething for something@cat2@otherSomething you would get /something/cat2/otherSomething other examples /OtherThing/cat1/otherSomething/Blah /OtherThing/cat4/otherSomething Where something, cat1, otherSomethign, etc are some sort of instances of ICategory There are certain rules that control what subcategories are valid and which subcategories are not acceptable, at the moment I m considering a heavy Object hierachy, but I know this is not a flexible solution, I d prefer the categories to be a bit more general but again, since there are rules about what can go next I m not sure how to do this. An example of a rule can be: OtherThing can only have subcategories cat1 and cat4 ( anything else is invalid) An option would be to use some sort of convention based aproach to instantiate a particular class given a subsection of the string(like cat4) but it seems a bit too complex, I m all ears Thanks

• A galaxy with stars, milkyway and other stuffs (WPF)

  - by boj

  What is a "realistic" way to build a galaxy in 2D with wpf? I'm not interessed in the physical modelling but the graphical aspect. At least the stars (position, size, color, pulsing etc.) should be generated from code. Generating milkyways would be nice. Main questions are: Stars: lens flare? texturing? Milkyway: bump mapping? "Far" stars: textures? generated? Pulsing? other elements, any effects are welcome! Some examples (taken from the web, I want to build similar pictures (animations) with wpf): Thank you.

• YUI Autocomplete: search after pasting?

  - by rassie

  I'm using an auto-complete widget from YUI to implement live search as in the examples. However, it works fine when search text is typed in, but fails to work when the text is pasted into the field. Which would be the proper way to initiate an autocompletion on paste? Haven't found anything for that in the documentation... EDIT: Pasting is not Ctrl-V, it's usually "Paste" from the context-menu. YUI does react to a keypress, but doesn't if anything is pasted by the mouse.

• When I'm iterating over two arrays at once, which one do I use as the limit?

  - by Martijn Courteaux

  Hi, I'm always struggling with something like the following Java example: String breads[] = {"Brown", "White", "Sandwich"}; int count[] = new int[breads.length]; for (int i = 0; i < ****; i++) { // Prompt the number of breads } ****: which array.length should I choose? I can choose between breads.length and count.length I know it would be the same result, but I don't know which one I shoud choose. There are many other examples where I get the same problem. I'm sure that you have encountered this problem as well in the past. What should you choose? Are there general agreements? Thanks

• Zend Framework - Database Table Singleton

  - by Sonny

  I have found myself doing this in my code to 'cache' the work done when instantiating my Zend_Db_Table models: if (Zend_Registry::isRegistered('x_table')) { $x_table = Zend_Registry::get('x_table'); } else { $x_table = new Default_Model_DbTable_X; Zend_Registry::set('x_table', $x_table); } It bothered me that this method isn't very DRY and it dawned on me today that a singleton pattern would probably be a better way to do this. Problem is, I've never written a singleton class. When I did some web searches, I found some offhand comments about Zend_Db_Table singletons, but no real examples. I already have meta-data caching configured. How do I make my Zend_Db_Table models singletons? Are there pitfalls or downsides?

• help understanding the concept of javascript callbacks with node.js, especially in loops

  - by Mr JSON

  hi I am just starting with node.js. I have done a little ajax stuff but nothing too complicated so callbacks are still kind of over my head. I looked at async but all I need is to run a few functions sequentially. I basically have something that pulls some json from an api, creates a new one and then does something with that. obviously i can't just run it because it runs everything at once and has an empty json. mostly they have to go sequentially but if while pulling a json from the api it can pull other json while it's waiting that is fine. I just got confused when putting the callback in a loop. what do I do with the index? i think i have seen some places that use callback inside the loop as kind of a recusive function and don't use for loops at all. simple examples would help alot thanks!

• jQuery Validation using the class instead of the name value

  - by Matt

  Hi, I'd like to validate a form using the jquery validate plugin, but I'm unable to use the 'name' value within the html - as this is a field also used by the server app. Specifically, I need to limit the number of checkboxes checked from a group. (Maximum of 3.) All of the examples I have seen, use the name attribute of each element. What I'd like to do is use the class instead, and then declare a rule for that. html This works: <input class="checkBox" type="checkbox" id="i0000zxthy" name="salutation" value="1" /> This doesn't work, but is what I'm aiming for: <input class="checkBox" type="checkbox" id="i0000zxthy" name="i0000zxthy" value="1" /> javascript: var validator = $(".formToValidate").validate({ rules:{ "salutation":{ required:true, }, "checkBox":{ required:true, minlength:3 } } }); Is it possible to do this - is there a way of targeting the class instead of the name within the rules options? Or do I have to add a custom method? Cheers, Matt

• In Log4Net XML configuration is Priority the same thing as Level?

  - by Michael Levy

  I inherited some code that uses the priority element under the root in its xml configuraiton. This is just like the example at http://iserialized.com/log4net-for-noobs/ which shows: <root> <priority value="ALL" /> <appender-ref ref="LogFileAppender" /> <appender-ref ref="ConsoleAppender"/> </root> However, the log4net configuration examples at http://logging.apache.org/log4net/release/manual/configuration.html always show it using the level element: <root> <level value="DEBUG" /> <appender-ref ref="A1" /> </root> In this type of configuration is <priority> the same as <level> ? Can someone point me to somewhere in the docs where this is explained?

• Using jep.invoke() method

  - by hofsoc

  Hi, I need to call a function from a python script and pass in parameters into it. I have a test python script which I can call and run from java using Jepp - this then adds the person. Eg Test.py import Finding from Finding import * f = Finding() f.addFinding("John", "Doe", 27) Within my Finding class I have addFinding(firstname, lastName, age) However, I wish to be able to do this from within java. Should I be using the jep.invoke() method. Does anyone have a hello world example of such a thing being done or forward me to some good examples? Does anyone have any suggestions please? Thanks in advance

• Resetting Objects vs. Constructing New Objects

  - by byronh

  Is it considered better practice and/or more efficient to create a 'reset' function for a particular object that clears/defaults all the necessary member variables to allow for further operations, or to simply construct a new object from outside? I've seen both methods employed a lot, but I can't decide which one is better. Of course, for classes that represent database connections, you'd have to use a reset method rather than constructing a new one resulting in needless connecting/disconnecting, but I'm talking more in terms of abstraction classes. Can anyone give me some real-world examples of when to use each method? In my particular case I'm thinking mostly in terms of ORM or the Model in MVC. For example, if I would want to retrieve a bunch of database objects for display and modify them in one operation.
