  • WCF error service error message with shared classes

    - by sevenalive
    Source code: http://code.google.com/p/sevenupdate/source/browse/#hg/Source/SevenUpdate.Base SevenUpdate.Base.Sui cannot be used since it does not match imported DataContract. Need to exclude this type from referenced types. Now I tried unchecking reuse reference types and I was able to get my project to compile. but when sending a collection from the client it was never received or couldn't be deserialized on the server end. I really need this to work. Any help would be appreciated, the fullsource code is provided by google code.

  • Why do software engineers hate writing documentation?

    - by Stewart Johnson
    I ask because I quite enjoy it! I'm talking about design documentation and implementation notes (NOT user manuals), which are non-existent in most of the codebases I've been handed. I can understand why a developer wouldn't want to write requirements (that's the analyst's job) or the user documentation (that's a technical writer's job) but I don't get why developers hate writing design docs. I don't think I would feel as if I'd finished the job if I only wrote the code and walked away -- mainly because when I've been introduced to code-only situations I've seen how hard it is to figure out what's been done and what the software does. I would hate for people to suffer the same situation when inheriting my code. What makes you loath writing supporting documentation for your code?

  • How do you perform macro expansion within #ifdef?

    - by Malvineous
    Hi all, I have some fairly generic code which uses preprocessor macros to add a certain prefix onto other macros. This is a much simplified example of what happens: #define MY_VAR(x) prefix_##x "prefix_" is actually defined elsewhere, so it will be different each time the file is included. It works well, but now I have some code I would like to skip if one of the tokens doesn't exist, but this doesn't work: #if defined MY_VAR(hello) What I want it to expand to is this: #ifdef prefix_hello But I can't figure out how. I need to use the MY_VAR() macro to do the expansion, so I can't just hardcode the name. (It's actually for some testing code, the same code gets included with a different prefix each time to test a bunch of classes, and I want to skip a couple of tests for a handful of the classes.) Is this possible with the C++ preprocessor?

  • Apps with lable XYZ could not be found

    - by HWM-Rocker
    Hello folks, today I ran into an error and have no clue how to fix it. Error: App with label XYZ could not be found. Are you sure your INSTALLED_APPS setting is correct? Where XYZ stands for the app-name that I am trying to reset. This error shows up every time I try to reset it (manage.py reset XYZ). Show all the sql code works. Even manage.py validate shows no error. I already commented out every single line of code in the models.py that I touched the last three monts. (function by function, model by model) And even if there are no models left I get this error. Here http://code.djangoproject.com/ticket/10706 I found a bugreport about this error. I also applied one the patches to allocate the error, it raises an exception so you have a trace back, but even there is no sign in what of my files the error occurred. I don't want to paste my code right now, because it is nearly 1000 lines of code in the file I edited the most. If someone of you had the same error please tell me were I can look for the problem. In that case I can post the important part of the source. Otherwise it would be too much at once. Thank you for helping!!!

  • Simple time profiling - strange times

    - by Gacek
    I'm trying to profile my code to check how long it takes to execute some parts of my code. I've wrapped my most time-consuming part of the code in something like that: DateTime start = DateTime.Now; ... ... // Here comes the time-consuming part ... Console.WriteLine((DateTime.Now - start).Miliseconds); The program is executing this part of code for couple of seconds (about 20 s) but in console I get the result of something about 800 miliseconds. Why is that so? What am I doing wrong?

  • Addressing "Access Denied" Exception with WMI Calls

    - by Joe
    I'm getting an exception with a message of "Access Denied" when executing against a WMI request. Some WMI requests appear to require higher security privileges than others. Ultimately my goal is to monitor process launches within the system and log. Regardless if there is a better approach, its now become a vendetta in getting this WMI approach to work. I've attempted the code at Security Tools - WMI Programming Using C#.Net and still receive the exception. If you copy the code found in the blog entry you can reproduce my issue. Another post on a similar topic can be found at link text but again, try the code and you'll the see the same security exception. How do I permit my code to execute these WMI requests? I'm running on Windows 7 Pro and VS 2010 in a new C# command line project.

  • How to generate C# documentation to a CHM or HTML file?

    - by BrunoLM
    Is there a way to generate a readable document file from the documentation on the code directly from Visual Studio? (also considering 2010) If there isn't, what should I use to create a CHM or HTML file? Code example: /// <summary> /// Convert a number to string /// </summary> /// <param name="number">An integer number to be converted to string</param> /// <returns>Number as string</returns> /// <example> /// <code> /// var s = MyMethod(5); /// </code> /// </example> /// <exception cref="Exception">In case it can't convert</exception> /// <remarks> /// Whatever /// </remarks> public string MyMethod(int number) { return number.ToString(); }

  • Measuring device drivers CPU/IO utilization caused by my program

    - by Lior Kogan
    Sometimes code can utilize device drivers up to the point where the system is unresponsive. Lately I've optimized a WIN32/VC++ code which made the system almost unresponsive. The CPU usage, however, was very low. The reason was 1000's of creations and destruction of GDI objects (pens, brushes, etc.). Once I refactored the code to create all objects only once - the system became responsive again. This leads me to the question: Is there a way to measure CPU/IO usage of device drivers (GPU/disk/etc) for a given program / function / line of code?

  • Way to get VS 2008 to stop forcing indentation on namespaces?

    - by Earlz
    I've never really been a big fan of the way most editors handle namespaces. They always force you to add an extra pointless level of indentation. For instance, I have a lot of code in a page that I would much rather prefer formatted as namespace mycode{ class myclass{ void function(){ foo(); } void foo(){ bar(); } void bar(){ //code.. } } } and not something like namespace mycode{ class myclass{ void function(){ foo(); } void foo(){ bar(); } void bar(){ //code.. } } } Honestly, I don't really even like the class thing being indented most of the time because I usually only have 1 class per file. And it doesn't look as bad here, but when you get a ton of code and lot of scopes, you can easily have indentation that forces you off the screen, and plus here I just used 2-space tabs and not 4-space as is used by us. Anyway, is there some way to get Visual Studio to stop trying to indent namespaces for me like that?

  • Link Error : xxx is already defined in *****.LIB :: What exactly is wrong?

    - by claws
    Problem: I'm trying to use a library named DCMTK which used some other external libraries ( zlib, libtiff, libpng, libxml2, libiconv ). I've downloaded these external libraries (*.LIB & *.h files ) from the same website. Now, when I compile the DCMTK library I'm getting link errors (793 errors) like this: Error 2 error LNK2005: __encode_pointer already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 3 error LNK2005: __decode_pointer already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 4 error LNK2005: __CrtSetCheckCount already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 5 error LNK2005: __invoke_watson already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 6 error LNK2005: __errno already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 7 error LNK2005: __configthreadlocale already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 8 error LNK2005: _exit already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Documentation: This seems to be a popular error for this library so, they do have a FAQ entry addressing this issue which ( http://forum.dcmtk.org/viewtopic.php?t=35 ) says: The problem is that the linker tries to combine different, incompatible versions of the Visual C++ runtime library into a single binary. This happens when not all parts of your project and the libraries you link against are generated with the same code generation options in Visual C++. Do not use the /NODEFAULTLIB workaround, because strange software crashes may follow. Fix the problem! DCMTK is by default compiled with the "Multithreaded" or "Multithreaded Debug" code generation option (the latter for Debug mode). Either change the project settings of all of your code to use these code generation options, or change the code generation for all DCMTK modules and re-compile. MFC users beware: DCMTK should be compiled with "Multithreaded DLL" or "Multithreaded DLL Debug" settings if you want to link the libraries into an MFC application. Solution to same problem for others: http://stackoverflow.com/questions/2259697/vscopengl-huge-amount-of-linker-issues-with-release-build-only says: It seems that your release build is trying to link to something that was built debug. You probably have a broken dependency in your build, (or you missed rebuilding something to release by hand if your project is normally built in pieces). More technically, you seem to be linking projects built with different C Run Time library settings, one with "Multi-Threaded", another one with "Multi-Threaded Debug". Adjust the settings for all the projects to use the very same flavour of the library and the issue should go away Questions: Till now I used to think that Name mangling is the only problem that may cause linking failures if its not been standardized. Just now I knew there are other things also which can cause same effect. Whats up with the "Debug Mode" (Multi-Threaded Debug) and "Release Mode" (Multi-Threaded)? What exactly is happening under the hood? Why exactly this thing is causing linking error? I wonder if there is something called "Single-Threaded Debug" and "Single-Threaded" which again causes the same thing. Documentation talks something about "Code Generation Options". What Code Generation Options? WTH are they? Documentation specifically warns us not to use /NODEFAULTLIB workaround. (example /NODEFAULTLIB :msvcrt ). Why? How would I cause troubles? what exactly is it? Please explain the last point in the documentation for MFC users. Because I'm going to use MFC later in this project. Explain Why should we do it? What troubles would it cause if I don't. Anything more you'd like to mention? I mean regarding similar errors. I'm very interested in Linker & its problems. So, if there are any similar things you can mentions them or some keywords atleast.

  • google maps not working anymore at the drop of a hat

    - by Vordreller
    2 days ago, I was working on a project that involves google maps. The website showed the maps on the pages just fine. Now, I come back to my workstation, nothing has changed, expect for the fact that the google maps won't show up anymore. The code is identical, nobody has touched my machine since I was gone, I've checked the html, everything is perfect and still this isn't working... The Javascript console is giving no errors and the code is identical to a backup I make everytime I call it a day. 2 days ago it was working, today it isn't. I've even copied the source code, put it into an html file and tried that, but the same result. I'm at a loss here. This is my code: <script type="text/javascript"> //<![CDATA[ var map; var directionsPanel; var directions; function initialize() { if (GBrowserIsCompatible()) { map = new GMap2(document.getElementById("map")); map.addControl(new GLargeMapControl()); map.addControl(new GScaleControl()); map.addControl(new GMapTypeControl()); //the route description directionsPanel = document.getElementById("route"); directions = new GDirections(map, directionsPanel); directions.load({COMMAND}); } } //]]> </script> The {COMMAND} is something that the PHP template will parse, I've checked it, the format is 100% correct and like I allready said, code now is identical to the backup, and if it worked back then, it should work now. Did google update their API overnight and did a function that I use here become deprecated? I don't know what's going on here...

  • Java HTTP Request Occasionally Hangs

    - by behrk2
    Hello Everyone, For the majority of the time, my HTTP Requests work with no problem. However, occasionally they will hang. The code that I am using is set up so that if the request succeeds (with a response code of 200 or 201), then call screen.requestSucceeded(). If the request fails, then call screen.requestFailed(). When the request hangs, however, it does so before one of the above methods are called. Is there something wrong with my code? Should I be using some sort of best practice to prevent any hanging? The following is my code. I would appreciate any help. Thanks! HttpConnection connection = (HttpConnection) Connector.open(url + connectionParameters); connection.setRequestMethod(method); connection.setRequestProperty("WWW-Authenticate", "OAuth realm=api.netflix.com"); if (method.equals("POST")) { connection.setRequestProperty("Content-type", "application/x-www-form-urlencoded"); } int responseCode = connection.getResponseCode(); System.out.println("RESPONSE CODE: " + responseCode); if (connection instanceof HttpsConnection) { HttpsConnection secureConnection = (HttpsConnection) connection; String issuer = secureConnection.getSecurityInfo() .getServerCertificate().getIssuer(); UiApplication.getUiApplication().invokeLater( new DialogRunner( "Secure Connection! Certificate issued by: " + issuer)); } if (responseCode != 200 && responseCode != 201) { screen.requestFailed("Unexpected response code: " + responseCode); connection.close(); return; } String contentType = connection.getHeaderField("Content-type"); ByteArrayOutputStream baos = new ByteArrayOutputStream(); InputStream responseData = connection.openInputStream(); byte[] buffer = new byte[20000]; int bytesRead = 0; while ((bytesRead = responseData.read(buffer)) > 0) { baos.write(buffer, 0, bytesRead); } baos.close(); connection.close(); screen.requestSucceeded(baos.toByteArray(), contentType); } catch (IOException ex) { screen.requestFailed(ex.toString()); }

  • How do i deploy UAT and Development SharePoint solution on the same server ?

    - by Nikhil Vaghela
    I am working on a SharePoint 2010 Server and i have following items in my SharePoint solution Couple of web parts State Machine Work flow (which will be integrated to an Infopath form library) Infopath task edit forms Lets say this solutions is deployed to http://[SharePoint201Server]:[PortNumber-x]/ This is the only server i have (No extra server for UAT), and what ever has been done so far needs to be given for user acceptance testing (UAT). I may create one more site at http://[SharePoint201Server]:[PortNumber-y]/ for it. My problme is that how do i maintain two copies of my source code ? I will have to continue development on the same set of source code for next UAT release. I simply can not create simple copies of the source code as it will have same Assembly name and feature id, etc..As if i do so, any changes on under Development source code would affect UAT assemblies. One thing i can do is to create seperate projects for UAT and Development with different Features and Assembly names, but is not that too much of an unneccesory work ? What can be the best approach in such situation ?

  • Variable declarations following if statements

    - by Anthony Pegram
    An issue came up on another forum and I knew how to fix it, but it revealed a feature of the compiler peculiar to me. The person was getting the error "Embedded statement cannot be a declaration or labeled statement" because they had a declaration of a variable following an if statement with no brackets. That was not their intent, but they had commented out the line of code immediately following the if statement, which made the variable declaration the de facto line of code to execute. Anyway, that's the background, which brings me to this. The following code is illegal if (true) int i = 7; However, if you wrap that in brackets, it's all legal. if (true) { int i - 7; } Neither piece of code is useful. Yet the second one is OK. What specifically is the explanation for this behavior? I have a hypothesis, but I'd rather ask the brilliant people on stackoverflow.

  • Gratuitous use of System.Runtime.Serialization attributes?

    - by rasx
    Is there any cost/drawback (apart from typing too much) to adorning a class with System.Runtime.Serialization attributes (like [DataContract]) such that it can be used locally as a direct reference to a desktop Client project or as a type for a WCF service? The goal here is to write a data-tier class that can be used in both rich client (WPF) and Web scenarios. My data classes will be in a project that is separate from Client and WCF (*.svc code-behind) code. Is this a valid attempt to reuse code?

  • Are large include files like iostream efficient? (C++)

    - by Keand64
    Iostream, when all of the files it includes, the files that those include, and so on and so forth, adds up to about 3000 lines. Consider the hello world program, which needs no more functionality than to print something to the screen: #include <iostream> //+3000 lines right there. int main() { std::cout << "Hello, World!"; return 0; } this should be a very simple piece of code, but iostream adds 3000+ lines to a marginal piece of code. So, are these 3000+ lines of code really needed to simply display a single line to the screen, and if not, do they create a less efficient program than if I simply copied the relevant lines into the code?

  • Custom QGraphicsItems not compiling and give object is is private error

    - by bahree
    Hi, I am trying to create a Custom QGraphicsItem button as shown by Fred here. The code which he posted can be found here. The problem is when I try and compile the code I get the following two errors: /usr/include/qt4/QtGui/qgraphicsitem.h ‘QGraphicsItem::QGraphicsItem(const QGraphicsItem&)’ is private /usr/include/qt4/QtCore/qobject.h ‘QObject::QObject(const QObject&)’ is private Here is the code snippet which essentially is the same as that in the sample above. The error is on the class deceleration. class MyButton : public QObject, public QGraphicsItem { Q_OBJECT Q_INTERFACES(QGraphicsItem) public: MyButton(QGraphicsItem *parent = 0); MyButton(const QString normal, const QString pressed = "", QGraphicsItem *parent = 0); .... } Interestingly the other sample as shown here works fine. The sample code for that can be found here. Any idea what is wrong? Thanks in advance.

  • Why is TransactionScope using a distributed transaction when I am only using LinqToSql and Ado.Net

    - by Ian Ringrose
    We are having problems on one machine, with the error message: "MSDTC on server XXX is unavailable." The code is using a TransactionScope to wrap some LingToSql database code; there is also some raw Ado.net inside of the transaction. As only a single sql database (2005) is being accessed, why is a distributed transaction being used at all? (I don’t wish to know how to enable MSDTC, as the code needs to work on the server with their current setup)

  • How to initiate chatting between two clients and two clients only, using applets and servlets?

    - by mithun1538
    Hello everyone, I first need to apologize for my earlier questions. (You can check my profile for them)They seemed to ask more questions than give answers. Hence, I am laying down the actual question that started all them absurd questions. I am trying to design a chat applet. Till now, I have coded the applet, servlet and communication between the applet and the servlet. The code in the servlet side is such that I was able to establish chatting between clients using the applets, but the code was more like a broadcast all feature, i.e. all clients would be chatting with each other. That was my first objective when I started designing the chat applet. The second step is chatting between only two specific users, much like any other chat application we have. So this was my idea for it: I create an instance of the servlet that has the 'broadcast-all' code. I then pass the address of this instance to the respective clients. 2 client applets use the address to then chat. Technically the code is 'broadcast-all', but since only 2 clients are connected to it, it gives the chatting between two clients feature. Thus, groups of 2 clients have different instances of the same servlet, and each instance handles chatting between two clients at a max. However, as predicted, the idea didn't materialize! I tried to create an instance of the servlet but the only solution for that was using sessions on the servlet side, and I don't know how to use this session for later communications. I then tried to modify my broadcast-all code. In that code, I was using classes that implemented Observer and Observable interfaces. So the next idea that I got was: Create a new object of the Observable class(say class_1). This object be common to 2 clients. 2 clients that wish to chat will use same object of the class_1. 2 other clients will use a different object of class_1. But the problem here lies with the class that implements the Observer interface(say class_2). Since this has observers monitoring the same type of class, namely class_1, how do I establish an observer monitoring one object of class_1 and another observer monitoring another object of the same class class_1 (Because notifyObservers() would notify all the observers and I can't assign a particular observer to a particular object)? I first decided to ask individual problems, like how to create instances of servlets, using objects of observable and observer and so on in stackoverflow... but I got confused even more. Can anyone give me an idea how to establish chatting between two clients only?(I am using Http and not sockets or RMI). Regards, Mithun. P.S. Thanks to all who replied to my previous (absurd) queries. I should have stated the purpose earlier so that you guys could help me better.

  • How do set up jquery to exclude classes in a function?

    - by user1497158
    I essentially only understand how to read bits of javascript and make modifications. I am using grid-slider, a script I purchased, but the code writer is mia at the moment, so hopefully someone here can help me. Basically, it's a slider and there are options to have links open like normal or to have links open in a panel on the same page. I want some links to open in a panel and others to open in the parent window. It seems to me that all that would be required to do this would be to activate the panel display function (which I've done) and then set up an exclude function to exclude certain uls or lis with a specific class from the function. I've read about the .not selector, but I don't see how to make it applicable to this code: enter code hereelse { enter code here if (this._displayOverlay) { if ($item.find(">.content").size() > 0) { $item.data("type", "static"); } else { var contentType = this.getContentType($link); var url = $link.attr("href"); $item.data({type:contentType, url:(typeof url != "undefined") ? url : ""}); } $item.css("cursor", "pointer").bind("click", {elem:this, i:i}, this.openOverlay); } $link.data("text", $item.find(">div:first").html()); $img = $link.find(">img"); } Can anyone help based on looking at this? Here's a link to the demo of the code: http://codecanyon.net/item/jquery-grid-style-slider/full_screen_preview/1204040 Thank you.
