    - by senthilmuthu
    Hi, I have added new Xib view file in my project.

I have set in info.plist file also xib file is also in landscape view. What do I have to do? Any help?

  • editing Rnw in Emacs, gets confused if in math mode or not

    - by stevejb
    When editing .Rnw files with emacs, sometimes it gets confused as to if I am in math mode or not. Then, the syntax highlighting gets messed up, and C-f-i inserts \textit{} and \mathit{} opposite to how it normally should. Is seems like there is some bool storing the state of math mode or not, and it gets inadvertently flipped. Is there a way I can manually flip it back?

  • Is this code thread-safe?

    - by mafutrct
    I've got a class with several properties. On every value update, a Store method is called with stores all fields (in a file). private int _Prop1; public int Prop1 { get { return _Prop1; } set { _Prop1 = value; Store(); } } // more similar properties here... private XmlSerializer _Ser = new ...; private void Store() { lock (_Ser) { using (FileStream fs = new ...) { _Ser.Serialize (fs, this); } } } Is this design thread-safe? (Btw, if you can think of a more appropriate caption, feel free to edit.)

  • Safe HttpContext.Current.Cache Usage

    - by Burak SARICA
    Hello there, I use Cache in a web service method like this : var pblDataList = (List<blabla>)HttpContext.Current.Cache.Get("pblDataList"); if (pblDataList == null) { var PBLData = dc.ExecuteQuery<blabla>( @"SELECT blabla"); pblDataList = PBLData.ToList(); HttpContext.Current.Cache.Add("pblDataList", pblDataList, null, DateTime.Now.Add(new TimeSpan(0, 0, 15)), Cache.NoSlidingExpiration, CacheItemPriority.Normal, null); } I wonder is it thread safe? I mean the method is called by multiple requesters And more then one requester may hit the second line at the same time while the cache is empty. So all of these requesters will retrieve the data and add to cache. The query takes 5-8 seconds. May a surrounding lock statement around this code prevent that action? (I know multiple queries will not cause error but i want to be sure running just one query.)

  • Forcing IE8 Standards Mode with FEATURE_BROWSER_EMULATION

    - by earls
    I'm doing this: http://blogs.msdn.com/b/ie/archive/2009/03/10/more-ie8-extensibility-improvements.aspx But it's not working. I have "iexplore.exe" set to 8888 (decimal mode) under MACHINE, but it's still coming up documentMode = 5. I thought 8888 was suppose to force IE8 Standards Mode whether you have a doctype or not. What is going on?

  • Missing safe control entry

    - by Stefan Hennicken
    I've got a working hello-world like webpart for my SPS3.0 I can compile, pack and deploy it using VS2008, makecab.exe and stsadm. So I know the theory of deploying sharepoint webparts. My problem: After I inserted an additional .webpart file, an elements.xml and a feature.xml to deploy the .webpart file and get knowledge about adding features to my webpart, the deployed webpart is missing its safe control entry in the web.config. But the dll can be found in the gac and my features are also deployed to the right folders. I didn't change anything in my manifest.xml especially not in it's -tag, because it definitely worked before i added my additional feature files. Can anybody help me? Should i provide you some code snippets? Thanks Stefan

  • Is this casting safe?

    - by Itsik
    I need to write a Util function (in my c++cli app) that converts a String to a Double or Float or Int. template<typename T> static T MyConvert(String^ str) { return static_cast<T>(System::Convert::ToDouble(str)); } Is this safe? Can it somehow convert 2 to 1.999 and then to 1 if I call MyConvert<int>("2") ? I was wondering why the Convert class isn't templated in the first place? (That would let me call Convert<T> instead of Convert.ToDouble() for all types) This is C++/Cli so I can use any convert methods in c++ or .net, but I only know Convert.ToDouble()|ToString()|ToInt32()) Thanks

  • Simulate Offline Mode for HTML5 Cache Testing

    - by Kevin Sylvestre
    I have an HTML5 application that requires offline support. I am using a local Apache server for the application, and am trying to figure out what the best way is to simulate offline mode (currently, in Firefox I disable my Air-Port to simulate offline mode, but this is a pain). Any suggestions? I am open to using other browsers if a method exists that doesn't require turning off my Internet.

  • how can i use switch statement on type-safe enum pattern

    - by Fer
    I found a goodlooking example about implementation enums in a different way. That is called type-safe enum pattern i think. I started using it but i realized that i can not use it in a switch statement. My implementation looks like the following: public sealed class MyState { private readonly string m_Name; private readonly int m_Value; public static readonly MyState PASSED= new MyState(1, "OK"); public static readonly MyState FAILED= new MyState(2, "ERROR"); private MyState(int value, string name) { m_Name = name; m_Value = value; } public override string ToString() { return m_Name; } public int GetIntValue() { return m_Value; } } What can i add to my class in order to be able to use this pattern in switch statements in C#? Thanks.

  • Vb6 project files and source safe

    - by Andrew
    A part of the application that I am working on is a legacy Vb6 Windows forms application. All the files in the project are under source control (VSS) except the Vb6 project file. From what I can establish from the other developers working on the project the reason for this is that the com components used in the projects have different references on each developers machine. I want to move the project files into VSS so that when files are added to the project these can be updated in the project files and other developers (and more importantly an automated build script) can get the latest project files from source safe. Does anyone know if/how I can achieve this in such a way as to not corrupt the references to other com components on different development machines?

  • Subversion (SVN) equivalant to Visual Source Safe (VSS) "Share"

    - by CraftyFella
    Hi, I have a scenario in my project where I need to share a single file between multiple projects in the same solution. Back in my Visual Source Safe days (Shudder), I'd use the "Share" option to allow me to make changes to this file in any of the locations. Then once it was checked in I could guarantee that the other locations will get the update. I'm trying to do this in Subversion but I can't seem to find the option anywhere. I do know about svn:externals however I'm only interested in sharing a single file between multiple locations. Does anyone know how to do this in Subversion? Thanks

  • Is it safe to catch EXCEPTION_GUARD_PAGE

    - by Michael J
    Environment is VC++ 9 on various Win platforms (XP and later) I'm writing an unhandled exception handler. I have a vague recollection from my kernel days that it was bad to catch an EXCEPTION_GUARD_PAGE, as this was generated to tell the OS to enlarge the stack. My question is twofold: Can such an exception occur in user space? If so, is it safe to catch it? I'm not especially interested in doing anything with it. I just want to know if I need to put special code in to not catch it (as I'm catching everything at the moment).

  • Replacement for HttpContext.Current.Request.ServerVariables["SERVER_NAME"] in Integrated Mode

    - by Donniel
    Hi, Using HttpContext.Current.Request.ServerVariables["SERVER_NAME"] in integrated mode gives an error in IIS7 as per: http://mvolo.com/blogs/serverside/archive/2007/11/10/Integrated-mode-Request-is-not-available-in-this-context-in-Application%5F5F00%5FStart.aspx Is there a replacement I can use in global.asax code for HttpContext.Current.Request.ServerVariables["SERVER_NAME"]? This would be similar to using String strPath = HttpContext.Current.Server.MapPath(HttpRuntime.AppDomainAppVirtualPath); instead of //String strPath = HttpContext.Current.Server.MapPath(HttpContext.Current.Request.ServerVariables["PATH_INFO"]);

  • PHP: Safe way to store decryptable passwords

    - by Jammer
    I'm making an application in PHP and there is a requirement that it must be possible to decrypt the passwords in order to avoid problems in the future with switching user database to different system. What encryption/decryption algorithm would you suggest? Is it good idea to just store the encrypted value and then compare the future authentication attempts to that value? Are the passwords still as safe as MD5/SHA1 when the private key is not available to the attacker (Hidden in USB drive for example)? I should still use salting, right? What encryption libraries should I use for PHP?

  • C++ Static Initializer - Is it thread safe

    - by Yan Cheng CHEOK
    Usually, when I try to initialize a static variable class Test2 { public: static vector<string> stringList; private: static bool __init; static bool init() { stringList.push_back("string1"); stringList.push_back("string2"); stringList.push_back("string3"); return true; } }; // Implement vector<string> Test2::stringList; bool Test2::__init = Test2::init(); Is the following code thread safe, during static variable initialization? Is there any better way to static initialize stringlist, instead of using a seperate static function (init)?

  • Are static delegates thread-safe?

    - by leypascua
    Consider this code snippet: public static class ApplicationContext { private static Func<TService> Uninitialized<TService>() { throw new InvalidOperationException(); } public static Func<IAuthenticationProvider> AuthenticationProvider = Uninitialized<IAuthenticationProvider>(); public static Func<IUnitOfWorkFactory> UnitOfWorkFactory = Uninitialized<IUnitOfWorkFactory>(); } //can also be in global.asax if used in a web app. public static void Main(string[] args) { ApplicationContext.AuthenticationProvider = () => new LdapAuthenticationProvider(); ApplicationContext.UnitOfWorkFactory = () => new EFUnitOfWorkFactory(); } //somewhere in the code.. say an ASP.NET MVC controller ApplicationContext.AuthenticationProvider().SignIn(username, true); Are delegates in the static class ApplicationContext thread-safe in the sense that multiple-threads can invoke them? What potential problems will I face if I pursue this approach?
