  • How to create a VS2010 extension that uses Language Services

    - by Hades32
    Creating extensions got much easier with Vs2010, but this seems not to be the case for everything... My aim: I wnat to make method calls and property uses of STATIC classes ITALIC. (Just like Eclipse and Java) I think I need to talk to the C# Language Service for this information, but searching for "Language Service" just yields results on how to CREATE one, not how to use one of the existing ones... To get this question a little more general: How do I get information about properties of the code (static/visibility etc) for using it in a VSX?

  • Toggle visibility of DIV based on Dropdown

    - by user1869787
    I have never used Javascript before, only HTML and CSS. I am attempting to have my information show only when selected from my drop down.

  • Cannot Debug Unmanaged Dll from C#

    - by JustSmith
    I have a DLL that was written in C++ and called from a C# application. The DLL is unmanaged code. If I copy the DLL and its .pdb files with a post build event to the C# app's debug execution dir I still can't hit any break points I put into the DLL code. The break point has a message attached to it saying that "no symbols have been loaded for this document". What else do I have to do to get the debugging in the dll source? I have "Tools-Options-Debugging-General-Enable only my code" Disabled. The DLL is being compiled with "Runtime tracking and disable optimizations (/ASSEMBLYDEBUG)" and Generate Debug Info to "Yes (/DEBUG)"

  • How is it that the abstract class XmlWriter can be instantiated using XmlWriter.Create(... ?

    - by Cognize
    Hi, Just looking to clarify my understanding of the workings of the XmlWriter and abstract classes in general. My thinking is (was) that an abstract class can not be instantiated, although it can contain base methods that can be used by an inheriting class. So, while investigating XmlWriter, I find that to instantiate the XmlWriter, you call XmlWriter.Create(.... , which returns an instance of... XmlWriter, which can then be used: FileStream fs = new FileStream("XML.xml", FileMode.Create); XmlWriter w = XmlWriter.Create(fs); XmlSerializer xmlSlr = new XmlSerializer(typeof(TestClass)); xmlSlr.Serialize(fs, tsIn); This clearly works, as tested. Can anyone help me understand what is going on here. As far as I can see there is or should be no 'instance' to work with here??

  • Unexpected generics behaviour

    - by pronicles
    I found strange generics behaviour. In two words - thing I realy want is to use ComplexObject1 in most general way, and the thing I realy missed is why defined generic type(... extends BuisnessObject) is lost. The discuss thread is also awailable in my blog http://pronicles.blogspot.com/2010/03/unexpected-generics-behaviour.html. public class Test { public interface EntityObject {} public interface SomeInterface {} public class BasicEntity implements EntityObject {} public interface BuisnessObject<E extends EntityObject> { E getEntity(); } public interface ComplexObject1<V extends SomeInterface> extends BusinessObject<BasicEntity> {} public interface ComplexObject2 extends BuisnessObject<BasicEntity> {} public void test(){ ComplexObject1 complexObject1 = null; ComplexObject2 complexObject2 = null; EntityObject entityObject1 = complexObject1.getEntity(); //BasicEntity entityObject1 = complexObject1.getEntity(); wtf incompatible types!!!! BasicEntity basicEntity = complexObject2.getEntity(); } }

  • Branchless memory manager?

    - by Richard Fabian
    Anyone thought about how to write a memory manager (in C++) that is completely branch free? I've written a pool, a stack, a queue, and a linked list (allocating from the pool), but I am wondering how plausible it is to write a branch free general memory manager. This is all to help make a really reusable framework for doing solid concurrent, in-order CPU, and cache friendly development. Edit: by branchless I mean without doing direct or indirect function calls, and without using ifs. I've been thinking that I can probably implement something that first changes the requested size to zero for false calls, but haven't really got much more than that. I feel that it's not impossible, but the other aspect of this exercise is then profiling it on said "unfriendly" processors to see if it's worth trying as hard as this to avoid branching.

  • Is this type of calculation to be put in Model or Controller?

    - by Hadi
    i have Product and SalesOrder model (to simplify, 1 sales_order only for 1 product) Product has_many SalesOrder SalesOrder belongs_to Product pa = Product A #2000 so1 = SalesOrder 1 order product A #1000, date:yesterday so2 = SalesOrder 2 order product A #999, date:yesterday so3 = SalesOrder 3 order product A #1000, date:now Based on the date, pa.find_sales_orders_that_can_be_delivered will give: SalesOrder 1 order product A #1000, date:yesterday SalesOrder 2 order product A #999, date:yesterday SalesOrder 3 order product A #1, date:now <-- the newest The question is: is find_sales_orders_that_can_be_delivered should be in the Model? i can do it in controller. and the general question is: what goes in Model and what goes in Controller. Thank you

  • Potential for SQL injection here?

    - by Matt Greer
    This may be a really dumb question but I figure why not... I am using RIA Services with Entity Framework as the back end. I have some places in my app where I accept user input and directly ask RIA Services (and in turn EF and in turn my database) questions using their data. Do any of these layers help prevent security issues or should I scrub my data myself? For example, whenever a new user registers with the app, I call this method: [Query] public IEnumerable<EmailVerificationResult> VerifyUserWithEmailToken(string token) { using (UserService userService = new UserService()) { // token came straight from the user, am I in trouble here passing it directly into // my DomainService, should I verify the data here (or in UserService)? User user = userService.GetUserByEmailVerificationToken(token); ... } } (and whether I should be rolling my own user verification system is another issue altogether, we are in the process of adopting MS's membership framework. I'm more interested in sql injection and RIA services in general)

  • Cannot run file_get_contents() on PHP 5.2.9-2

    - by Obay
    Hello, I am having the same problem as described below. http://marc.info/?l=php-general&m=124104032703506 The guy answered his own question by: "Sorry, didn't pay attention to the registered streams :-( You need to install a PHP package with ssl or compile it with --with-openssl." What does that mean? I'm fairly new to all this stuff and I don't quite understand what he was talking about, (e.g. registered streams, ssl). We have another server that has SSL. Does he mean that if I just transfer to that server, problem solved? Or is there anything else I need to consider? Can you please help me out? Any help is much appreciated :)

  • Advice needed: What tech expertise do I need to accomplish my goal?

    - by quaternion
    I have a business plan & money to hire a developer - the essentials involve simple online games for children (played via traditional computer over the internet) such that their scores are uploaded to a database that can be viewed via a nice portal. What I don't know is: what technologies I would want my developer to know (the only somewhat unusual requirement I have is that the games have relatively accurate timing of keypresses/mouse presses) how much I should expect to pay (in general, what is the appropriate range) how many hours a program of the complexity of a simple tower defense -type game should take to develop (to be clear, the idea is not to implement TD, but rather other games of similar complexity) whether I should go with capable acquaintances, some online kind of online web-dev bidding site, or just try to find a capable undergraduate at the local university who I can wow with his/her first big paycheck, how I should communicate the software's specifications to my hired developer... Is there a standard I should be using? whether I should hire a webdev consultant for a few hours to help me answer these questions, instead of asking stackoverflow Thanks for any advice!

  • Calling a function of en external javascript file

    - by strakastroukas
    Hello. In general... How can I make a call on a function of an external javascript file? More specific... In the head tag i have <script type="text/javascript" src="JScript/FontSize.js"></script> The external javascript file, (that i would like to call) FontSize.js contains the following functions. function checkCookie() function setCookie(c_name, value, expiredays) function getCookie(c_name) function increaseFontSize() function decreaseFontSize() The FontSize.js is located at the ~/Jscript/ directory I guess the body on load should contain something like <body onload="/JScript/Fontsize.js/checkCookie()"> Of course nothing works as it should because, i do not know how to make the call to a function to an external js file

  • NS2, Otcl: using a variable of an owned instance within a class

    - by Hussain
    Hello all, I'm using NS2 to create some new classes in C++ and then link them to otcl. The linkage and everything works, but when I try to use the otcl variables in an object, I'm having a trouble. For example, suppose I have a class "Node" with the variable X. In the code I want to set this value and later on use it in some if-statements. Setting the variable is no problem using this code: $node1 set x 4 Now the problem I'm having is when I try to use this variable x anywhere. In C++ we could use a general variable (i.e. y) and say "y=node.x and then use y in some if-statements. I have tried to look for a method to perform the same thing in otcl, but failed. Any help is appriciated. Thanks in Advance.

  • Understanding OpenGL Matrices

    - by Omega
    I'm starting to learn about 3D rendering and I've been making good progress. I've picked up a lot regarding matrices and the general operations that can be performed on them. One thing I'm still not quite following is OpenGL's use of matrices. I see this (and things like it) quite a lot: x y z n ------- 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 So my best understanding, is that it is a normalized (no magnitude) 4 dimensional, column-major matrix. Also that this matrix in particular is called the "identity matrix". Some questions: What is the "nth" dimension? How and when are these applied? My biggest confusion arises from how OpenGL makes use of this kind of data.

  • Variable alpha blending in pylab

    - by Hooked
    How does one control the transparency over a 2D image in pylab? I'd like to give two sets of values (X,Y,Z,T) where X,Y are arrays of positions, Z is the color value, and T is the transparency to a function like imshow but it seems that the function only takes alpha as a scalar. As a concrete example, consider the code below that attempts to display two Gaussians. The closer the value is to zero, the more transparent I'd like the plot to be. from pylab import * side = linspace(-1,1,100) X,Y = meshgrid(side,side) extent = (-1,1,-1,1) Z1 = exp(-((X+.5)**2+Y**2)) Z2 = exp(-((X-.5)**2+(Y+.2)**2)) imshow(Z1, cmap=cm.hsv, alpha=.6, extent=extent) imshow(Z2, cmap=cm.hsv, alpha=.6, extent=extent) show() Note: I am not looking for a plot of Z1+Z2 (that would be trivial) but for a general way to specify the alpha blending across an image.

  • Smoothing Small Data Set With Second Order Quadratic Curve

    - by Rev316
    I'm doing some specific signal analysis, and I am in need of a method that would smooth out a given bell-shaped distribution curve. A running average approach isn't producing the results I desire. I want to keep the min/max, and general shape of my fitted curve intact, but resolve the inconsistencies in sampling. In short: if given a set of data that models a simple quadratic curve, what statistical smoothing method would you recommend? If possible, please reference an implementation, library, or framework. Thanks SO!

  • Allow single-line accessor (getter/setter) syntax with Checkstyle

    - by Sam3
    We'd like to have trivial Java property accessors using a single line syntax, so they take up much much less space, and are more readable (in terms of 'seeing' the set of accessors quickly). But we do want to enforce multi-line method syntax for everything else in our checkstyle configuration. But I'm not sure how to make this exception for accessors in Checkstyle config and suspect it may not be possible. So we'd like our accessors to look something like this: public String getFoo() { return foo; } public void setFoo(String foo) { this.foo = foo; } [In fact we'd rather not have trivial accessors at all and instead just annotate the private member variables with @Property or something and have the accessors generated for us, since writing endless get and set code delivers no real benefit, but that's a general Java frustration and an aside as far as this question goes.]

  • IE 8 dialog windows not decompressing files

    - by Mike
    Hi, I've got a website where we have pre-compressed all of our HTML files. In general this works fine, but since IE 8 has come out some people are finding that they can not use some parts of the website. We've used the showModalDialog command to open a dialog window and pointing to one of our pre-compressed files but it displays it just show up as strange characters (ie not decompressed). Now it only happens in the dialog. I'm pretty sure our compression is all fine because the page they are viewing to open the dialog is also compressed. Has anyone else come across this or got any suggestions cuz i'm stumped??? Thanks, Mike

  • Subversion commit conflict

    - by dvanaria
    I use Subversion mainly to synchronize work between two computers I use on a daily basis (and as a backup, since I have a checked-out copy of the repository on each computer). I keep the main repository on a USB flashdrive. I recently came across the following error when trying to commit a current working copy (and both working copies, one on each computer, are identical now): ! C career\UVaOnlineJudge\Log.doc local delete, incoming delete upon update ! C career\UVaOnlineJudge\102\Main.class local delete, incoming delete upon update Without going into more detail about what I did to get the repository out of synch, my question is more general. What does “local delete, incoming delete upon update” mean? What is Subversion expecting that I’m not giving it?

  • Find a missing 32bit integer among a unsorted array containing at most 4 billion ints

    - by pierr
    Hi, This is the problem described in Programming pearls. I can not understand binary search method descrbied by the author. Can any one helps to elaborate? Thanks. EDIT: I can understand binary search in general. I just can not understand how to apply binary search in this special case. How to decide the missing number is in or not in some range so that we can choose another. English is not my native language, that is one reason I can not understand the author well. So, use plain english please:) EDIT: Thank you all for your great answer and comments ! The most important lesson I leant from solving this question is Binary search applies not only on sorted array!

  • Help need to with MySQL query to join data spanning multiple tables and use data as column names

    - by gurun8
    I need a little help putting together a SQL query that will give me the following resultsets: and The data model looks like this: The tricky part for me is that the columns to the right of the "Product" in the resultset aren't really columns in the database but rather key/value pairs spanned across the data model. Table data is as follows: My apologies in advance for the image heavy question and the image quality. This just seemed like the easiest way to convey the information. It'll probably take someone less time to write the query statement to achieve the results than it did for me to assemble this question. By the way, the "product_option" table image is truncated but it illustrated the general idea of the data structure. The MySQL server version is 5.1.45.

  • Using Parallel Extensions In Web Applications

    - by Greg
    I'd like to hear some opinions as to what role, if any, parallel computing approaches, including the potential use of the parallel extensions (June CTP for example), have a in web applications. What scenarios does this approach fit and/or not fit for? My understanding of how exactly IIS and web browsers thread tasks is fairly limited. I would appreciate some insight on that if someone out there has a good understanding. I'm more curious to know if the way that IIS and web browsers work limits the ROI of creating threaded and/or asynchronous tasks in web applications in general. Thanks in advance.

  • Is there a DRMAA Java library that works with Torque/PBS?

    - by dondondon
    Does anybody know a Java implementation of the DRMAA-API that is known to work with PBS/Torque cluster software? The background behind this: I would like to submit jobs to a newly set-up linux cluster from java using a DRMAA compliant API. The cluster is managed by PBS/Torque. Torque includes PBS DRMAA 1.0 library for Torque/PBS that contains a DRMA-C binding and provides in libdrmaa.so and .a binaries. I know that Sun grid engine includes a drmaa.jar providing a Java-DRMAA API. In fact I opted to use SGE but it was decided to try PBS first. The theory behind that decision was: 'DRMAA is a standard and therefore a Java API needs only a standards compliant drmaa-c binding.' However, I couldn't find such 'general DRMAA-C-java API' and now assume that this assumption is wrong and that the Java libraries are engine specific. Are we stuck here? Any comments appreciated.

  • Difference between 'scope' and 'namespace'?

    - by katriel
    What is the difference, in general, between the concepts of namespaces and scope? To my understanding, both describe the parts of a program in which a variable/object/method/function will be accessible. I understand that 'scope' tends to be a property of the variable (e.g., "This variable has global scope"), while a 'namespace' is a property of the program (e.g., "A Python function creates a local namespace"). Are there other differences? Global scope vs global namespace addresses a slightly narrower question: global namespaces in C++. http://www.alan-g.me.uk/tutor/tutname.htm states, There are a few very subtle differences between the terms but only a Computer Scientist pedant would argue with you, and for our purposes namespace and scope are identical. What are those subtle differences? Under what circumstances or with which kinds of languages do people use each concept?

  • Reading data from a socket, considerations for robustness and security

    - by w.brian
    I am writing a socket server that will implement small portions of the HTTP and the WebSocket protocol, and I'm wondering what I need to take into consideration in order to make it robust/secure. This is my first time writing a socket-based application so please excuse me if any of my questions are particularly naive. Here goes: Is it wrong to assume that you've received an entire HTTP request (WebSocket request, etc) if you've read all data available from the socket? Likewise, is it wrong to assume you've only received one request? Is TCP responsible for making sure I'm getting the "message" all at once as sent by the client? Or do I have to manually detect the beginning and end of each "message" for whatever protocol I'm implementing? Regarding security: What, in general, should I be aware of? Are there any common pitfalls when implementing something like this? As always, any feedback is greatly appreciated.
