  • Why do WCF clients depend on the app.config file?

    - by routeNpingme
    Like a lot of things, I'm sure there's a good reason for this, so please help me understand... Why, by default, do WCF services store settings in app.config? This has been so frustrating trying to work with multiple Silverlight class libraries. These class libraries are supposed to be completely independent from each other, and this dependency on the app.config seems to cause the following headaches: Single Responsibility Principle - I should be able to add a reference to a class library and go. If that class library uses a service reference, this idea is shot before I even start coding against it. Muddy Configuration - To get other libraries to work, I have to copy and paste the service configurations into the "main" application configs. If an endpoint changes in any way, I can't just worry about a new version of that class DLL - I have to worry about anything that uses it, too. Complex Alternatives - Programmatically creating the endpoint isn't pretty. Period. There has to be a better way. Why doesn't WCF at least separate the service configurations into a ServiceName.config or something that gets copied to an output directory. What am I missing? How do you deal with this?

  • "rsAccessDenied" error for SSRS 2008

    - by JackLocke
    Hi All, I have been trying to access SSRS Web Service URL hxxp://myServer:80/ReportServer (from Reporting Service Configuration Manager), but my IE always shows "rsAccessDenied" message saying that my account doesn't have privilage required to view. Here are my system specs. Its my laptop with Windows 7 x64, and SQL Server 2008 with SP1 and I am using Mixed Mode Authentication with My account as SysAdmin privilages and this is what I have been trying / tried ... (ofcourse with restarting the service everytime I make any change in configuration), I changed service account from Reporting Service Configuration Manager to make it use My account but nothing happend. I tried running my IE as admin, by RUN AS ADMIN but still same message. Then I read somewhere I have to delete/recreate my encryption keys as well, so I tried again with that, then it was asking me to enter ID/PWD to access server here I am totally blank because it was not accepting my account credentials !!!. Weird thing is I can see my existing reports if I follow this URL hxxp://myServer:80/Reports , for which My guess is solely used to view reports. I have read post here about kind of same problem, but it seems that OP just left forum after asking question... Also, MSDN does have these helps hxxp://msdn.microsoft.com/en-us/library/ms156034.aspx hxxp://msdn.microsoft.com/en-us/library/bb630430.aspx but both of this didn't workout for me. I will really appriciate it if any one can help me out. Jack p.s. I was not allowed to post more than 1 URL because of my "reputation" so I had to change the string a bit. Please replace hxxp wih http in URLs.

  • Unity 1.2 Dependency injection of internal types

    - by qvin
    I have a facade in a library that exposes some complex functionality through a simple interface. My question is how do I do dependency injection for the internal types used in the facade. Let's say my C# library code looks like - public class XYZfacade:IFacade { [Dependency] internal IType1 type1 { get; set; } [Dependency] internal IType2 type2 { get; set; } public string SomeFunction() { return type1.someString(); } } internal class TypeA { .... } internal class TypeB { .... } And my website code is like - IUnityContainer container = new UnityContainer(); container.RegisterType<IType1, TypeA>(); container.RegisterType<IType2, TypeB>(); container.RegisterType<IFacade, XYZFacade>(); ... ... IFacade facade = container.Resolve<IFacade>(); Here facade.SomeFunction() throws an exception because facade.type1 and facade.type2 are null. Any help is appreciated.

  • I did my own web framework: now, how keep it sync with applications? must I use versions?

    - by Daniel Koch
    ... and I did the first web application using it, now I'm going to create the second. In this first web application I enhanced the framework's core library with new things and promptly updated framework branch. I'm using bazaar to keep framework and web application committed. The application was in the beginning, a full branch of framework source tree, now I'm updating framework manually at every change on core files. (copying changed files from web app to framework's branch). With this second web application that I'm going to create, I need to know about versions (or revisions) which the application is based. If I found a bug in this version I can fix and then sync files with first web application no worrying: functions will be the same to this application. If I'm going to make changes in core (new behavior, new functions in library or something new in source tree) it must be named as "new version". What's the best way to do this? Because I'm using a Distributed Version Control System (bazaar), I'm not dealing with VERSIONS, but revision numbers that change every time. Please fresh my mind with new ideas.

  • PHP package manager

    - by Mathias
    Hey, does anyone know a package manager library for PHP (as e.g. apt or yum for linux distros) apart from PEAR? I'm working on a system which should include a package management system for module management. I managed to get a working solution using PEAR, but using the PEAR client for anything else than managing a PEAR installation is not really the optimal solution as it's not designed for that. I would have to modify/extend it (e.g. to implement actions on installation/upgrade or to move PEAR specific files like lockfiles away from the system root) and especially the CLI client code is quite messy and PHP4. So maybe someone has some suggestions for an alternative PEAR client library which is easy to use and extend (the server side has some nice implementations like Pirum and pearhub) for completely different package management systems written in PHP (ideally including dependency tracking and different channels) for some general ideas how to implement such a PM system (yes, I'm still tinkering with the idea of implementing such a system from scratch) I know that big systems like Magento and symfony use PEAR for their PM. Magento uses a hacked version of the original PEAR client (which I'd like to avoid), symfony's implementation seems quite integrated with the framework, but would be a good starting point to at least write the client from scratch. Anyway, if anybody has suggestions: please :)

  • Unable to get data from a WCF client

    - by Scott
    I am developing a DLL that will provide sychronized time stamps to multiple applications running on the same machine. The timestamps are altered in a thread that uses a high performance timer and a scalar to provide the appearance of moving faster than real-time. For obvious reasons I want only 1 instance of this time library, and I thought I could use WCF for the other processes to connect to this and poll for timestamps whenever they want. When I connect however I never get a valid time stamp, just an empty DateTime. I should point out that the library does work. The original implementation was a single DLL that each application incorporated and each one was synced using windows messages. I'm fairly sure it has something to do with how I'm setting up the WCF stuff, to which I am still pretty new. Here are the contract definitions: public interface ITimerCallbacks { [OperationContract(IsOneWay = true)] void TimerElapsed(String id); } [ServiceContract(SessionMode = SessionMode.Required, CallbackContract = typeof(ITimerCallbacks))] public interface ISimTime { [OperationContract] DateTime GetTime(); } Here is my class definition: [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)] public class SimTimeServer: ISimTime The host setup: // set up WCF interprocess comms host = new ServiceHost(typeof(SimTimeServer), new Uri[] { new Uri("net.pipe://localhost") }); host.AddServiceEndpoint(typeof(ISimTime), new NetNamedPipeBinding(), "SimTime"); host.Open(); and the implementation of the interface function server-side: public DateTime GetTime() { if (ThreadMutex.WaitOne(20)) { RetTime = CurrentTime; ThreadMutex.ReleaseMutex(); } return RetTime; } Lastly the client-side implementation: Callbacks myCallbacks = new Callbacks(); DuplexChannelFactory pipeFactory = new DuplexChannelFactory(myCallbacks, new NetNamedPipeBinding(), new EndpointAddress("net.pipe://localhost/SimTime")); ISimTime pipeProxy = pipeFactory.CreateChannel(); while (true) { string str = Console.ReadLine(); if (str.ToLower().Contains("get")) Console.WriteLine(pipeProxy.GetTime().ToString()); else if (str.ToLower().Contains("exit")) break; }

  • JBoss 6 unpacks jars from WEB-INF/lib of war

    - by Maxym
    when I start JBoss 6 I see that it unpacks all jar files from WEB-INF/lib in tmp/vfs/automountXXX folder. E.g. jackrabbit-server.war contains library asm-3.1.jar, then in tmp folder I see the following folders with files: asm-3.1.jar-83dc35ead0d41d41/asm-3.1.jar asm-3.1.jar-2a48f1c13ec7f25d/contents/"unpacked asm-3.1.jar" it does not take files from my.ear/lib only WEB-INF/lib... Why is it so? And is here any way to prevent it doing so? It just slows down application server starting (and stopping), what is not that comfortable at development... If it is somehow related to JavaEE 6 specification and ejb-jars, which can be located now in WEB-INF/lib, so I don't have such libraries in my war files... UPDATE: actually when I repack jackrabbit-server.war to jackrabbit-server.ear which contains jackrabbit-server.war and moved all its libraries to jackrabbit-server.ear/lib then I still see two folders in tmp: asm-3.1.jar-215a36131ebb088e/asm-3.1.jar asm-3.1.jar-14695f157664f00/contents/ but in this case last folder is empty. So it still creates two folders, but does not unpack my library. Also I use exploded deployment so the question is only about jar files, not unpacking ear/war.

  • Boost Date_Time problem compiling a simple program

    - by Andry
    Hello! I'm writing a very stupid program using Boost Date_Time library. int main(int srgc, char** argv) { using namespace boost::posix_time; date d(2002,Feb,1); //an arbitrary date ptime t1(d, hours(5)+nanosec(100)); //date + time of day offset ptime t2 = t1 - minutes(4)+seconds(2); ptime now = second_clock::local_time(); //use the clock date today = now.date(); //Get the date part out of the time } Well I cannot compile it, compiler does not recognize a type... Well I used many features of Boost libs like serialization and more... I correctly built them and, looking in my /usr/local/lib folder I can see that libboost_date_time.so is there (a good sign which means I was able to build that library) When I compile I write the following: g++ -lboost_date_time main.cpp But the errors it showed me when I specify the lib are the same of those ones where I do not specify any lib. What is this? Anyone knows? The error is main.cpp: In function ‘int main(int, char**)’: main.cpp:9: error: ‘date’ was not declared in this scope main.cpp:9: error: expected ‘;’ before ‘d’ main.cpp:10: error: ‘d’ was not declared in this scope main.cpp:10: error: ‘nanosec’ was not declared in this scope main.cpp:13: error: expected ‘;’ before ‘today’

  • Programatically rebuild .exd-files when loading VBA

    - by aspartame
    Hi, After updating Microsoft Office 2007 to Office 2010 some custom VBA scripts embedded in our software failed to compile with the following error message: Object library invalid or contains references to object definitions that could not be found. As far as I know, this error is a result of a security update from Microsoft (Microsoft Security Advisory 960715). When adding ActiveX-controls to VBA scripts, information about the controls are stored in cache files on the local hard drive (.exd-files). The security update modified some of these controls, but the .exd-files were not automatically updated. When the VBA scripts try to load the old versions of the controls stored in the cached files, the error occurs. These cache-files must be removed from the hard drive in order for the controls to load successfully (which will create new, updated .exd-files automatically). What I would like to do is to programatically (using Visual C++) remove the outdated .exd-files when our software loads. When opening a VBA project using CApcProject::ApcProject.Open I set the following flag:axProjectThrowAwayCompiledState. TestHR(ApcProject.Open(pHost, (MSAPC::AxProjectFlag) (MSAPC::axProjectNormal | MSAPC::axProjectThrowAwayCompiledState))); According to the documentation, this flag should cause the VBA project to be recompiled and the temporary files to be deleted and rebuilt. I've also tried to update the checksum of the host application type library which should have the same effect. However none of these fixes seem to do the job and I'm running out of ideas. Help is very much appreciated!

  • Learning libraries without books or tutorials

    - by Kawili-wili
    While many ask questions about where to find good books or tutorials, I'd like to take the opposite tack. I consider myself to be an entry-level programmer ready to move up to mid-level. I have written code in c, c++, c#, perl, python, clojure, vb, and java, so I'm not completely clueless. Where I see a problem in moving to the next level is learning to make better use of the literally hundreds upon hundreds of libraries available out there. I seem paralyzed unless there is a specific example in a book or tutorial to hand-hold me, yet I often read in various forums where another programmer attempts to assist with a question. He/she will look through the docs or scan the available classes/methods in their favorite IDE and seem to grok what's going on in a relatively short period of time, even if they had no previous experience with that specific library or function. I yearn to break the umbilical chord of constantly spending hour upon hour searching and reading, searching and reading, searching and reading. Many times there is no book or tutorial, or if there is, the discussion glosses over my specific needs or the examples shown are too far off the path for the usage I had in mind or the information is outdated and makes use of deprecated components or the library itself has fallen out of mainstream, yet is still perfectly usable (but no docs, books, or tutorials to hand-hold). My question is: In the absence of books or tutorials, what is the best way to grok new or unfamiliar libraries? I yearn to slicken the grok path so I can get down to the business of doing what I love most -- coding.

  • How to avoid user keep trying login using Ruby on Rails?

    - by Tattat
    I want to create a login page, it can easy implement using Ruby on Rails. But the login is very simple, but I want more security. I want to stop the user keep trying the password. So, I have some ideas on that. First, stop login feature if the user keep trying the password for 15 mins. After the user login fail 5 times in 15 mins, the system should not allow the user login again in next 15 mins, ever his/her password is correct. Second, I want to add a human verification, after the user tried 5 times. After the user wait for 15 mins to login, I want to add an addition verification to the user. I want the user click the password, and the CAPTCHA image. If one of them is failed, they still can't login the system. He/She have 5 times to try, if he / she failed again, he/she need to want another 15 mins. Third, After the user tried 15 times, and still can't get into the system. I want to lock the user account, the user will receive an email, with a link to assign the password again. So, the question is "Is there any library to implement such authorization easily?" I know it can be implemented using code, but using library is much convenient. Also, I want to ask is there any security suggestion for that? thank u.

  • Classes with the same name - is it restricted only within the same translation unit?

    - by LeopardSkinPillBoxHat
    Let's just I had the following code: foo.h class Foo { // ... }; foo.cpp #include "foo.h" // Functions for class Foo defined here... Let's say that Foo are built into a static library foo.lib. Now let's say I have the following: foo2.h class Foo { // ... }; foo2.cpp #include "foo2.h" // Functions for class Foo defined here... This is built into a separate static library foo2.lib. Now, if I re-link foo.lib and foo2.lib into an executable program foo.exe, should it be complaining that class Foo has been defined twice? In my experiences, neither the compiler or the linker are complaining. I wouldn't be expecting the compiler to complain, because they have been defined in separate translation units. But why doesn't the linker complain? How does the linker differentiate between the 2 versions of the Foo class? Does it work by decorating the symbols?

  • What VC++ compiler/linker does when building a C++ project with Managed Extension

    - by ???
    The initial problem is that I tried to rebuild a C++ project with debug symbols and copied it to test machine, The output of the project is external COM server(.exe file). When calling the COM interface function, there's a RPC call failre: COMException(0x800706BE): The remote procedure call failed. According to the COM HRESULT design, if the FACILITY code is 7, it's actually a WIN32 error, and the win32 error code is 0x6BE, which is the above mentioned "remote procedure call failed". All I do is replace the COM server .exe file, the origin file works well. When I checked into the project, I found it's a C++ project with Managed Extension. When I checking the DLL with reflector, it shows there's 2 additional .NET assembly reference. Then I checked the project setting and found nothing about the extra 2 assembly reference. I turned on the show includes option of compiler and verbose library of linker, and try to analyze whether the assembly is indirectly referenced via .h file. I've collect all the .h file and grep all the files with '#using' '#import' and the assembly file itself. There really is a '#using ' in one of the .h file but not-relevant to the referenced assembly. And about the linked .lib library files, only one of the .lib file is a side-product of another managed-extension-enabled C++ project, all others are produced by a pure, traditional C++ project. For the managed-extension-enabled C++ project, I checked the output DLL assembly, it did NOT reference to the 2 assembly. I even try to capture the access of the additional assembly file via sysinternal's filemon and procmon, but the rebuild process does NOT access these file. I'm very confused about the compile and linking process model of a VC++/CLI project, where the additional assembly reference slipped into the final assembly? Thanks in advance for any of your help.

  • How do I generate reports in R?

    - by Maiasaura
    I've been struggling for a week now trying to figure out how to generate reports in R using either Sweave or Brew. I should say right at the beginning that I have never used Tex before but I understand the logic of it. I have read this document several times. However, I cannot even get a simple example to parse. Brew successfully converts a simple markup file (just a title and some text) to a .tex file (no error). But it never ever converts tex to a pdf. > library(tools) > library(brew) > brew("population.brew", "population.tex") > texi2dvi("population.tex", pdf = TRUE) The last step always fails with: Error in texi2dvi("population.tex", pdf = TRUE) : Running 'texi2dvi' on 'population.tex' failed. What am I doing wrong? The report I am trying to build is fairly simple. I have 157 different analysis to summarize. Each one has 4 plots, 1 table and a summary. I just want output plot 1,2,3,4 output table \pagebreak ... that's it. Can anyone help me get further? I use osx, don't have Tex installed. thanks

  • TextArea component is null on applicationComplete event

  • Apache redirection problem!!!!

    - by vikas
    Hi guys, I am setting up a pre-built website built in php. The site was actually hosted on the linux server. Now I am trying to set it up on a Window machine with WAMP server. In this website almost every page request passes through a particular file called redirect(which is basically a php file without extension). Now the problem is that when I inspected the configuration(httpd.conf, apache.conf,.htaccess, vhost.conf etc) of the apache server on the linux machine, I nowhere found the redirect rules for doing so. Neither mod_rewrite nor mod_alias rules for this redirection were found there. But is still redirects the request properly. I also noticed that Zend Framework library is there in the exact same directory where the redirect file is. This library is included in the include_path in php.ini. However, the web site is still not developed using Zend MVC and I have seen NO proof of ZEND being used there. So I am really confused how this redirection is working there? I am unable to set up this on window machine without rewrite rules of mod_rewrite or mod_alias. Do you guys know any alternative of both the said modules for redirection? I know the site is really weird, but i have to set it up. :) Thanks in advance for your help.

  • GNU C++ how to check when -std=c++0x is in effect?

    - by TerryP
    My system compiler (gcc42) works fine with the TR1 features that I want, but trying to support newer compiler versions other than the systems, trying to accessing TR1 headers an #error demanding the -std=c++0x option because of how it interfaces with library or some hub bub like that. /usr/local/lib/gcc45/include/c++/bits/c++0x_warning.h:31:2: error: #error This file requires compiler and library support for the upcoming ISO C++ standard, C++0x. This support is currently experimental, and must be enabled with the -std=c++0x or -std=gnu++0x compiler options. Having to supply an extra switch is no problem, to support GCC 4.4 and 4.5 under this system (FreeBSD), but obviously it changes the picture! Using my system compiler (g++ 4.2 default dialect): #include <tr1/foo> using std::tr1::foo; Using newer (4.5) versions of the compiler with -std=c++0x: #include <foo> using std::foo; Is there anyway using the pre processor, that I can tell if g++ is running with C++0x features enabled? Something like this is what I'm looking for: #ifdef __CXX0X_MODE__ #endif but I have not found anything in the manual or off the web. At this rate, I'm starting to think that life would just be easier, to use Boost as a dependency, and not worry about a new language standard arriving before TR4... hehe.

  • How to implement a category hierarchy using collections

    - by Luke101
    Hello, I have about 200 categories that are nested. I am currently reading the documention on the C5 generics library. I am not sure if the C5 library is overkill or not. I am looking at converting all my custom algorithms to the C5 implemention. This is what I need. If a certain category is chosen i need to find its parents, siblings, direct children, and all children. This is the way I have it set up. To find the: Parents: I start from the current location then loop through the list and find the current parent. When I find the parent I loop through the whole list again to find the next parent and so on. Siblings: I loop through the whole list and find all the nodes that have the same parent as the choosen node. direct children: I loop through the whole list and find all nodes that is a parent of the choosen node. All Children: This one took me a while to figure out. But I used recursion to find all children of the choosen node. Is there a better way to implement something like this?

  • How to check whether user is login in web application?

    - by Morgan Cheng
    I want to learn the whole details of web application authentication. So, I decided to write a CodeIgniter authentication library from scratch. Now, I have to make design decision about how to determine whether one user is login. Basically, after user input username & password pair. A cookie is set for this session, following navigations in the web application will not require username & password. The server side will check whether the session cookie is valid to determine whether current user is login. The question is: how to determine whether cookie is valid cookie issued from server side? I can image the most simple way is to have the cookie value stored in session status as well. For each HTTP request, compare the value from cookie and the value from server session. (Since CodeIgniter session library store session variables in cookies, it is not applicable without some tweak.) This method requires storage in server side. For huge web application that is deployed in multiple datacenters. It is possible that user input username & password when browsing in one datacenter, while he/she access the web application in another datacenter later. The expected behavior is that user just input username & password once. As a result, all datacenters should be able to access the session status. That is possible not applicable even the session status is stored in external storage such as database. I tried Google. I login Google with Asian proxy which is supposed to direct me to datacenters in Asian. Then I switch to North American proxy which should direct me to datacenters in North America. It recognize my login without asking username and password again. So, is there any way to determine whether user is login without server side session status?

  • Klazuka/Kal incorporation issue

    - by user1292943
    I'm having a little issue. I am trying to incorporate the Klazuka/Kal project into my project. I've done the following: I added the Kal.xcodeproj and all files to my project Under Build Phases, I've added Kal to "Target Dependencies" Under Build Phases, I've added libKal.a under "Link Binary With Libraries" Under Build Phases, I've added Kal.bundle to "Copy Bundle Resources" Under Build Settings, I've added "“$(BUILT_PRODUCTS_DIR)” (or “$(BUILT_PRODUCTS_DIR)/static_library_name”" for "Header Search Paths" and "User Header Search Paths". Under Build Settings, I've added the path to Kal under "Library Search Paths" Under Build Settings, I've added -ObjC, -all_load, and -force_load under "Other Linker Flags" I've edited my Build Scheme and list the Kal Target prior to my main application target with Analyze, Test, Run, Profile, and Archive all checked. I've attempted to follow the steps from here on Stack Overflow: iphone: Kal calendar not running in xcode 4.2 and here: Trying to integrate a Calendar library that was built for versions of iOS before iOS5 into my new project in XCode 4 using iOS5 - How to port? and here: I added my project and Kal Calendar's project in a workspace, still won't work in Xcode 4 and also on this site: http://blog.carbonfive.com/2011/04/04/using-open-source-static-libraries-in-xcode-4/#configuring_the_projects_scheme I try to import the "Kal.h" file but am getting a File Not Found error when I try to build. I'm obviously missing something, just not sure what. Can anyone please help? Thanks for any assistance!!

  • Modify existing struct alignment in Visual C++

    - by Crend King
    Is there a way to modify the member alignment of an existing struct in Visual C++? Here is the background: I use an 3rd-party library, which uses several structs. To fill up the structs, I pass the address of the struct instance to some functions. Unfortunately, the functions only returns unaligned buffer, so that data of some members are always wrong. /Zp is out of choice, since it breaks the other parts of the program. I know #pragma pack modifies the alignment of the following struct, but I do not want to copy the structs into my code, for the definitions in the library might change in the future. Sample code: test.h: struct am_aligned { BYTE data1[10]; ULONG data2; }; test.cpp: include "test.h" // typedef alignment(1) struct am_aligned am_unaligned int APIENTRY wWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow) { char buffer[20] = {}; for (int i = 0; i < sizeof(unaligned_struct); i++) { buffer[i] = i; } am_aligned instance = *(am_aligned*) buffer; return 0; } instance.data2 is 0x0f0e0d0c, while 0x0d0c0b0a is desired. The commented line does not work of course. Thanks for help!
