  • Passing to service custom class instance in WCF

    - by hgulyan
    Hi, I have my custom class Customer with its properties. I added DataContract mark above the class and DataMember to properties and it was working fine, but I'm calling a service class's function, passing customer instance as parameter and some of my properties get 0 values. While debugging I can see my properties values and after it gets to the function, some properties' values are 0. Why it can be so? There's no code between this two actions. DataContract mark workes fine, everything's ok. Any suggestions on this issue? I tried to change ByRef to ByVal, but it doesn't change anything. Why it would pass other values right and some of integer types just 0? Maybe the answer is simple, but I can't figure it out. Thank You. _ Public Class Customer Private Type_of_clientField As Integer = -1 _ Public Property type_of_client() As Integer Get Return Type_of_clientField End Get Set(ByVal value As Integer) Type_of_clientField = value End Set End Property End Class _ _

  • Tricks to avoid losing motivation?

    - by AareP
    Motivation is a tricky thing to upkeep. Once I thought that ambitious projects will keep programmer motivated, and too simple tasks will hinder his motivation. Now I have plenty of experience with small and large projects, desktop/web/database programming, c++/c#/java/php languages, oop/non-oop paradigms, day-job/free-time programming.. but I still can't answer the question of motivation. Which programming tasks I like, and which don't? It seems to depend on too many variables. One thing remains constant though. It's that starting everything from scratch is always more motivating than extending some existing system. Unfortunately it's hard to use this trick in productive programming. :) So my question is, what tricks programmer can use to stay motivated? For example should we use pen and paper as much as possible, in order not to get fed up with monitor and keyboard?

  • Branch prediction , correlation bit

    - by Maciej Adrzej
    Problem ; Consider following simplified code fragment; if (d==0) d=1; if (d==1) ... Construct the action table for the 1-bit predictor with 1-bit correlation assuming predictor initialized to NOT TAKEN and the correlation bit is initialized to TAKEN. The value of d alternates 1,2,1,2 Note count the instances of misprediction. I tried to solve question my answer is ; |d=?|B1 |B1 |New B1 |B2 |B2 | New B2 | | |Prediction|Action|Prediction|Prediction|Action|Prediction| |1 | NT/NT | T | T/NT | NT/NT | NT | NT/NT | |2 | T/NT | T | T/NT | NT/NT | T | NT/T | |1 | T/NT | T | T/NT | NT/T | NT | NT/NT | |2 | T/NT | T | T/NT | NT/NT | T | NT/T | I doubt whether it is true or not ? Any idea ?

  • Android app copy protection and data files

    - by Ben Mc
    I'm going to rephrase this question. As it turns out the original answer wasn't definitive and problems were found. ======================================================================= In my app, I access my sqlite database at the following hard-coded location in my code: /data/data/com.mydomain.appname/databases/database.db If I turn ON copy protection in the Market Place, will my app still have access to this location? Or will I have to change it to something like: */data-private/*data/com.mydomain.appname/databases/database.db (or something like this) Since I have a Dev phone only, I have no way of testing to see if my app still functions normally after turning on copy protection. Thank you!

  • How can I prompt user for additional permissions on page load?

    - by Rew
    Note: The application I'm building is a website type Facebook Application that uses Facebook Connect. I can prompt the user with a request for Extended Permissions using the following FBML code: <fb:prompt-permission perms="read_stream,publish_stream"> Grant permission for status updates </fb:prompt-permission> Taken from here. This creates a link on the page that must be clicked by the user in order to trigger the prompt to display. My question is: Is it possible to display this prompt automatically, when the page loads, without requiring the user to click on the link? Also, in reply to the answer below, I'd like to avoid displaying the link. Would prefer a neat way to do this, if that fails the least dirty method will do :-)

  • How do I get the same key bindings in vmware's Window and Mac [closed]

    - by ragnarius
    I have a macbook but sometimes I run Windows in vmware to program in Visual Studio. I have a swedish keyboard, to get the curly brace '{' I press alt(=option)+shift+8 in mac, but to get the same character in vmware/windows I should press alt+7. Obviously, I would like to have the same keyboard layout in mac and windows, how can I make this happen? I have been recommended to use autohotkey on Windows, but I have a problem mapping AltGr shift 8 to a character (i.e. <^!+8:{ does not work) (I state the question in this forum because I think that only programmers can answer it, we are the only ones that use the characters []{} )

  • PHP - Is possible to find if user is browsing from beind a Router and get Router Info

    - by Fábio Antunes
    Hello guys. I think it isn't possible just using PHP, but just to be sure. Is it possible for PHP to know if the user is accessing the web from behind a Router? And if yes, how can i get some information about that router, like: Router Name, Brand, Serial Number, ... Users connected in the same network. Can PHP also find the Local IP Address for the visitor in that Network? A few simple questions. To which i haven't found a solid answer, and i tough that some PHP genius could tell me. And teach me. Thanks for your help.

  • Enumerating all open file handles and/or registry handles in Windows Mobile / Windows CE 5.x

    - by jdstroy
    Hi all, Is there a way to enumerate all open file handles and/or registry handles in Windows Mobile 5 / Windows CE 5.x? In particular, I'd like to get the handles for all processes in the system, and not just the ones for my application. This would be similar to the list of handles in Sysinternals's Process Explorer for Win32 or Sysinternals's handle.exe I anticipate that someone will ask "Is this absolutely necessary for your application?" My answer to that would be "I think so, unless there's a better way to get a list of all open file names and registry key names." The goal is to provide diagnostic information about an application that crashes and fails to uninstall properly, but that worked properly at one time on the same device. (I do not have debugging information for the buggy application.)

  • how to make a universal iphone/ipad app programmatically, navigation controller for iphone and spli

    - by arash13
    I couldn't find a good answer anywhere. I am using a UINavigationController for my iphone app and everything is done 100% programmatically no xibs. So i am trying to port my app to ipad, i tried to use a UISplitViewController and link my existing tableView and etc.. Now, i am not sure where should i have the logic of my program separating the viewcontroller for iphone or ipad.. do i setup my main file to use a different appdelegate or i use a same appdelegae and have the condition set up there ? now beside this, whenever i try to complile my app on the simulator it does not recognize the uisplitview and even the condition in which i check if the class exists. can please someone put me in the right direction.. and remember i am not using xibs?

  • Automated builds of BizTalk 2009 projects using Team System 2008 Build

    - by Doug
    I'm trying to configure automated build of BizTalk 2009 projects using Team Foundation Server 2008. We have a staging server which has BizTalk 2009 installed. I ran the Team Foundation Server Build Setup on this server, and it can build non-BizTalk projects OK. However, BizTalk projects fail to build. I suspected something was amiss when "Deployment" was not a valid build type! I tried copying various things over from a developer PC which has BizTalk and Visual Studio 2008 installed, but still couldn't get it to work. I don't really want to install Visual Studio on the staging server, but without it the "Developer Tools and SDK" option in the BizTalk install is greyed out. I guess I need this in order for BizTalk projects to compile. So, my question is can a BizTalk 2009 server be used as a TFS build agent to build BizTalk projects without having Visual Studio installed. If the answer is no, what's the smallest part of VS that can be installed to get this to work? Thanks in advance.

  • which is best algorithm?

    - by Lopa
    Consider two algorithms A and B which solve the same problem, and have time complexities (in terms of the number of elementary operations they perform) given respectively by a(n) = 9n+6 b(n) = 2(n^2)+1 (i) Which algorithm is the best asymptotically? (ii) Which is the best for small input sizes n, and for what values of n is this the case? (You may assume where necessary that n0.) i think its 9n+6. guys could you please help me with whether its right or wrong?? and whats the answer for part b. what exactly do they want?

  • Prototyping Object in Javascript breaks jQuery?

    - by blesh
    I have added a simple .js to my page that has some pretty mundane common-task sort of functions added to the Object and Array prototypes. Through trial and error I've figured out that adding any function to Object.prototype, no matter it's name or what it does causes javascript errors in jQuery: The culprit? Object.prototype.foo = function() { /*do nothing and break jQuery*/ }; The error I'm getting line 1056 of jquery-1.3.2.js, in the attr:function { } declaration: /*Object doesn't support this property or method*/ name = name.replace(/-([a-z])/ig, function(all, letter) { return letter.toUpperCase(); }); Apparently G.replace is undefined. While it's obvious that there's something I'm just not wrapping my head around with prototyping, I'm failing miserably to figure out what it is. To be clear, I'm not looking for a workaround, I have that handled... what I'm looking for is an answer to 'Why?'. Why does adding a function to Object.prototype break this bit of code?

  • CMS Preventing Bad HTML Insertion by Client?

    - by Jascha
    I'm building a small CMS in PHP for a client and something I've noticed that comes up fairly often is a client will enter a bit of HTML in a field without closing his/her tag. I'm wondering if there is some parsing technique to prevent bad HTML from rendering my whole output page in italics because the user forgot to add a closing </i> tag. I'm not worried about XSS or malicious html, just a forgotten tag here and there as it's the client who is managing the content. Forgive me if this is a duplicate question, I did some searching, but could not find an appropriate answer. -J

  • Event Capturing vs Event Bubbling

    - by Rajat
    I just wanted to get the general consensus on which is a better mode of event delegation in JS between bubbling and capturing. Now I understand that depending on a particular use-case, one might want to use capturing phase over bubbling or vice versa but I want to understand what delegation mode is preferred for most general cases and why (to me it seems bubbling mode). Or to put it in other words, is there a reason behind W3C addEventListener implementation to favor the bubbling mode. [capturing is initiated only when you specify the 3rd parameter and its true. However, you can forget that 3rd param and bubbling mode is kicked in] I looked up the JQuery's bind function to get an answer to my question and it seems it doesn't even support events in capture phase (it seems to me because of IE not support capturing mode). So looks like bubbling mode is the default choice but why?

  • Sql Server 2008 Install

    - by Steve
    I already have Visual Studio 2008 installed. When installing developer Sql Server 2008, do I need to check the Business Intelligence Development Studio option? I'm guessing not. I assume if I already have VS 2008, the install will just add the relevant Sql Server related project types into VS 2008. EDIT: I marked the question answered before I did the install - I've installed Sql Server before and I thought this was what happened, but on doing this install, leaving the BI studio option unchecked does NOT install the SQL Server projects in Visual Studio. I had to go back and install it, so the answer is... Check it! I was overthinking the install - it's smart enough not to install VS twice.

  • Eclipse software management

    - by Maroloccio
    How to streamline/automate the configuration of Eclipse? Given N developers running a mixture of Ubuntu and Mac OS X, all with the same version of Eclipse, how to make sure that: Each developer, on top of his favourite "Available Software Sites" selection, has a common set of installation sources? Each developer has an easy (automated?) way of installing a base set of plug-ins? Each developer can just as easily install a custom plugin developed in-house and distributed over the local network? No automatically deployed plugins conflict with any others a developer might already be using? I would post this to serverfault.com if it wasn't that I am more interested in a "scripting" answer than a traditional "system management" solution... ;-)

    - by John Retallack
    I have the following problem : I am given a tree with N apples, for each apple I am given it's weight and height,I can pick apples up to a given height H,each time I pick an apple the height of every apple is increased with U(also given).I have to find out the maximum weight of apples I can pick. e.g: N=4 H=100 U=10 (height-eight) apple1: 91 10 apple2: 82 30 apple3: 93 5 apple4: 94 15 The answer is 45 : I first pick the apple with the weight of 15 then the one with the weight of 30. I would like to know if someone here could help me with giving me an hint on how I should approach this problem. Thank you.

  • What do I return if the return type of a method is Void? (Not void!)

    - by DR
    Due to the use of Generics in Java I ended up in having to implement a function having Void as return type: public Void doSomething() { //... } and the compiler demands that I return something. For now I'm just returning null, but I'm wondering if that is good coding practice... I've also tried Void.class, void, Void.TYPE, new Void(), no return at all, but all that doesn't work at all. (For more or less obvious reasons) (See this answer for details) So what am I supposed to return if the return type of a function is Void? What's the general use of the Void class? EDIT: Just to spare you the downvotes: I'm asking about V?oid, not v?oid. The class Void, not the reserved keyword void.

  • Having problems with a mask in C#

    - by Nard Dog
    I guess this would be a DevExpress mask, but here is what I have: var dlEdit = new DevExpress.XtraEditors.Repository.RepositoryItemTextEdit(); dlEdit.Mask.MaskType = MaskType.RegEx; dlEdit.Mask.EditMask = "\\d{1,10}"; I'm trying to get a number that can be up to 10 digits in length that WILL accept leading 0's, as it is now it will show the leading 0's (ex. 0032421243) until the field is clicked off in which case it removes them. I tried a numeric masktype but same thing only it wouldn't let me enter the 0's to start with at all. I thought this would be my answer but this custom type isn't. Can someone point me in the right direction for what I need? Maybe a different type of mask or something?

  • What are the best programming and development related Blogs?

    - by Christopher Cashell
    There are lots of great resources available on the Internet for learning more about programming and improving your skills. Blogs are one of the best, IMO. There's a wealth of knowledge and experience, much of it covering topics not often found in traditional books, and the increased community aspect helps to bring in multiple viewpoints and ideas. We're probably all familiar with Coding Horror and Joel on Software (so no need to mention them), but what are the other great ones out there? What are the Blogs that you find yourself following most closely? Where you see the best new ideas, the most interesting or informative ideas, or just the posts that make you sit back and think? One Blog per answer, and then we'll vote up the best so we can all learn from them.

  • Hidden Features of HTML

    - by Binoj Antony
    HTML being the most widely used language (at least as a markup language) has not gotten its due credit. Considering that it has been around for so many years, things like the FORM / INPUT controls have still remained same with no new controls added. So at least from the existing features, do you know any that are not well known but very useful. Of course, this question is along the lines of: Hidden Features of JavaScript Hidden Features of CSS Hidden Features of C# Hidden Features of VB.NET Hidden Features of Java Hidden Features of ASP.NET Hidden Features of Python Hidden Features of TextPad Hidden Features of Eclipse Do not mention features of HTML 5.0, since it is in working draft Please specify one feature per answer.
