  • Select calls seems to not time out.

    - by martsbradley
    HI Folks, I have a threaded C++ program where up to three threads are calling select on a three separate socket descriptors waiting for data to become available. Each thread handles one socket and adds it to the readfds with a timeout of 300 seconds. After select returns if there is data available I'm calling recv to read it. Is there anything that I need to be aware of with winsock and threads because for some reason after a number of hours the select calls all seem to be not timing out. Can a multi threaded program select from a number of threads without issue? I know that I should have one thread listening to all three sockets however that would be a large change for this app and I'm only looking to apply a bug fix. cheers, Martin.

  • Want to understand C++ sentry object

    - by Romain Hippeau
    I answered this [question][1] and somebody else had answered as he modern C++ equivalent would be a sentry object: construct it at the beginning of a function, with its constructor implementing call(), and upon return (or abnormal exit), its destructor implements I am not familiar with using sentry objects in C++. I thought they were limited to input and output streams. Could somebody explain to me about C++ sentry objects as well as how to use them as an around interceptor for one or more methods in a class ?

  • .NET Application with SQL Server CE Database

    - by blu
    I just started using SQL Server CE 3.5 in my WinForms Application (C# in VS 2008 SP1). I've noticed a couple of interesting things I'd like some input on: 1. Copying of sdf file to bin My sdf file is located inside of an Infrastructure project that houses my repository implementations. When the application is first debugged the sdf was copied to debug\bin. This is where all future reads/writes operate. At some point when this is deployed the file will go into a data folder using Click Once, but during development where should I be putting this sdf? Is having it in the bin typical, or are there any other recommendations? 2. Updating sdf It appears that writing to the sdf file does not immediately update the database. I am using Linq-to-SQL and am calling SubmitChanges, but on read the values are not returned. However if I close the application and re-open it the added value is there. Is there an additional flush step I need to take? What is causing this, file locking, buffering, something else? Update 3. Unit Tests I have an MS test project, and the sdf file is not being copied to the correct output directory. I have the settings: Build Action: Content Copy to Output Directory: Copy Always The message is: System.Data.SqlServerCe.SqlCeException: The database file cannot be found. Check the path to the database. I appreciate any guidance on these questions, thanks. If there is a tutorial other than what is on MSDN that you know about that would be great too. Working with CE is proving to be a difficult task and I welcome any help I can find.

  • How to detect a Socket disconnection?

    - by AngryHacker
    I've implemented a task using the async Sockets pattern in Silverlight 3. I started with Michael Schwarz's implementation and built on top of that. So basically, my Silverlight app establishes a persistent socket connection to a device and then data flows both ways as necessary between the device and the Silverlight app. One thing I am struggling with is how to detect disconnection. I could think of 2 approaches: Keep-Alive. I know this can be done at the Sockets level, but I am not sure how to do this in an async model. How would the Socket class let me know there has been a disconnection. Manual keep alive. Basically, I am having the Silverlight app send a dummy packet every 20 seconds or so. If it fails, I'd assume disconnection. However, incredibly, SocketAsyncEventArgs.SocketError always reports success, even if I simply unplug the device that the Silverlight app is connected to. I am not sure whether this is a bug or what or perhaps I need to upgrade to SL4. Any ideas, direction or implementation would be appreciated.

  • (this == null) in C#!

    - by SLaks
    Due to a bug that was fixed in C# 4, the following program prints true. (Try it in LINQPad) void Main() { new Derived(); } class Base { public Base(Func<string> valueMaker) { Console.WriteLine(valueMaker()); } } class Derived : Base { string CheckNull() { return "Am I null? " + (this == null); } public Derived() : base(() => CheckNull()) { } } In VS2008 in Release mode, in throws an InvalidProgramException. (In Debug mode, it works fine) In VS2010 Beta 2, it doesn't compile (I didn't try Beta 1); I learned that the hard way Is there any other way to make this == null in pure C#?

  • Building SL4 + RIAServices app takes too long on VS2010.

    - by adlanelm
    Got a Win7 box with VS2010 Premium installed on it. Building desktop apps works just fine. But we got this solution with 15 SL4 and 21 desktop projects... Building the SL part of it takes too long. This is very irritating and encourages to drop TDD since every time I run a test it takes ~3 seconds for msbuild to find out that nothing changed and the project should be skipped. The projects are very small and there's nothing fancy in them and we hadn't any problems before we switched from VS2008+SL3. I've heard people complaining abound VS2010 speed in general, but nothing about SL4 build time. Is anyone experiencing same problems and is there any workaround for this?

  • HowTo: Conditional Page Break in SSRS 2010 ?

    - by SwissCoder
    Hi there I just migrated a project from .NET 3.5 to 4.0, accordingly the reports now use SSRS included in .net 4.0/VS2010. Before conditionally setting a rectangles visibility did the trick for me. (inside the rectangle I put a rectangle with a pagebreak) But this stopped working now.. any help appreciated

  • directX texture appears incorrectly

    - by numerical25
    I finally managed to get a texture onto a cube sadly, but it is appearing incorrectly. as the below picture identifies. Anyways, I am not sure what it could be. My first guess is it could be my uv mapping or my vertex positioning is off. If someone could check and make sure thats good. The first element is the vertex position, second is the color, and third is the uv texture. //Create vectors and put in vertices // Create vertex buffer VertexPos vertices[] = { // BACK SIDES { D3DXVECTOR3(-5.0f, 5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(0.0,0.0)}, { D3DXVECTOR3(-5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(1.0,1.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(-5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(1.0,1.0)}, { D3DXVECTOR3(5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(1.0,1.0)}, // 2 FRONT SIDE { D3DXVECTOR3(-5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f), D3DXVECTOR2(0.0,0.0)}, { D3DXVECTOR3(5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f) , D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f), D3DXVECTOR2(1.0,1.0)}, // 3 { D3DXVECTOR3(-5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,0.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(-5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(-5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,2.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, // 4 { D3DXVECTOR3(-5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(0.0,0.0)}, { D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, -5.0f, -5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, // 5 { D3DXVECTOR3(5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(0.0,0.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, -5.0f, 5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(0.0,2.0)}, // 6 {D3DXVECTOR3(-5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,0.0)}, {D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, {D3DXVECTOR3(-5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, {D3DXVECTOR3(-5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, {D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, {D3DXVECTOR3(-5.0f, -5.0f, 5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, }; My second guess could be an error that I am receiving as I run the program.

  • understanding a Build c++

    - by numerical25
    I think I know what a build is. But I am not sure. My definition of a build is another word for saying compiled application. Can someone please tell me what exactly a build is. And why do people ask for 2 types of builds. Such as Debug Build, Profile Build and a Release Build. What are the differences.

  • How work with common utils project.

    - by ais
    For example, I have some project Common.Utils.csproj and use it in all other projects. I can store its (Utils) sourses in one repository and modify it only there, register dll in gac and use it as dll in other projects, or I can clone sourse anywhere I need, include project in solution, use it as source and push modifications. So, what is best practice?

  • Getting all the classes in project and their packages from CodeRush extension

    - by drasto
    I've spent some time trying to find a way CodeRush could add using when it finds undeclared element that is in the fact class name with no using added. The solution suggested in this answer to my question (Refactor_resolve) does not work (bugged?). In a process I found out that writing plug-ins for CodeRush is easy, so I decided to code this functionality myself (and share it). I'd only implement a CodeProvider (like in this tutorial). The only thinks I need to do the job are answers to this questions: At the start up of my plugin I need to get a list (set, map, whatever) of all classes and their packages. This means all the classes(interfaces...) and their packages in project, and within all referenced libraries. And I also need to receive updated on this (when user adds reference, creates new class). Can I get this from some CodeRush classes or maybe VS interface available from CodeProvider class? How do I add created CodeProvider to the pop-up that is shown when user hovers over an Issue?

  • Converting VS 2008 Project to VS 2010 - now .aspx won't load

    - by coffeeaddict
    I converted all my other projects fine from VS 2008 to 2010 and they run great. There is one project however for some reason after converting, when I try to run one of the .aspx pages in it, I get nothing...no error, just that it cannot display the page. Nothing has changed. The path is still the same, and the IIS website is still the same. I even recreated the site in IIS using the VS option to create it in the web project properties. This is a testing project..only has like one .aspx in it. Not sure why I get nothing after converting this. I did not convert it to .NET 4.0, it's still in v3.5 in VS 2010.

  • Extra space while installing .msi

    - by Cristina
    I have extra space in my custom made .msi. The data to be installed has about 600MB and the installer says it needs 1.4 GB.Switching to a different location then the predetermined one (e.g from C:\Program Files\My_App to F:\My_App) shows that it always need approximately 800 MB on the Windows partition, which is in my case the extra space. Any thoughts on why is this happening? Also can this cause an installation error on a 64-bit OS? I've only installed it on a 32-bit OS and everything is fine, but one of my colleagues is having problems installing it on the above mentioned type.

    Hello -- We are moving our SL3 app to SL4. First step was to open it in VS2010; it converted w/o problem. However, parameters specified for the start page are not passed along. That is, if we specify ourStartPage.aspx?Slam=Dunk&Glass=Sun in app.xaml.cs, Application_Startup(), e.InitParams is empty. How do we fix this? Thanks for any advice.... (Note that the very same startup string worked in VS2008.)

  • How to limit TCP writes to particular size and then block untlil the data is read

    - by ustulation
    {Qt 4.7.0 , VS 2010} I have a Server written in Qt and a 3rd party client executable. Qt based server uses QTcpServer and QTcpSocket facilities (non-blocking). Going through the articles on TCP I understand the following: the original implementation of TCP mentioned the negotiable window size to be a 16-bit value, thus maximum being 65535 bytes. But implementations often used the RFC window-scale-extension that allows the sliding window size to be scalable by bit-shifting to yield a maximum of 1 gigabyte. This is implementation defined. This could have resulted in majorly different window sizes on receiver and sender end as the server uses Qt facilities without hardcoding any window size limit. Client 1st asks for all information it can based on the previous messages from the server before handling the new (accumulating) incoming messages. So at some point Server receives a lot of messages each asking for data of several MB's. This the server processes and puts it into the sender buffer. Client however is unable to handle the messages at the same pace and it seems that client’s receiver buffer is far smaller (65535 bytes maybe) than sender’s transmit window size. The messages thus get accumulated at sender’s end until the sender’s buffer is full too after which the TCP writes on sender would block. This however does not happen as sender buffer is much larger. Hence this manifests as increase in memory consumption on the sender’s end. To prevent this from happening, I used Qt’s socket’s waitForBytesWritten() with timeout set to -1 for infinite waiting period. This as I see from the behaviour blocks the thread writing TCP data until the data has actually been sensed by the receiver’s window (which will happen when earlier messages have been processed by the client at application level). This has caused memory consumption at Server end to be almost negligible. is there a better alternative to this (in Qt) if i want to restrict the memory consumption at server end to say x MB's? Also please point out if any of my understandings is incorrect.

  • VS2008 Link Error Using SafeInt3.hpp in 64bit mode.

    - by photo_tom
    I have the below code that links and runs fine in 32bit mode - #include "safeint3.hpp" typedef SafeInt<SIZE_T> SAFE_SIZE_T; SAFE_SIZE_T sizeOfCache; SAFE_SIZE_T _allocateAmt; Where safeint3.hpp is current version that can be found on Codeplex SafeInt. For those who are unaware of it, safeint is a template class that makes working with different integer types and sizes "safe". To quote channel 9 video on software - "it writes the code that you should". Which is my case. I have a class that is managing a large in-memory cache of objects (6gb) and I am very concerned about making sure that I don't have overflow/underflow issues on my pointers/sizes/other integer variables. In this use, it solves many problems. My problem is coming when moving from 32bit dev mode to 64bit production mode. When I build the app in this mode, I'm getting the following linker warnings - 1>cachecontrol.obj : warning LNK4006: "bool __cdecl IntrinsicMultiplyUint64(unsigned __int64 const &,unsigned __int64 const &,unsigned __int64 *)" (?IntrinsicMultiplyUint64@@YA_NAEB_K0PEA_K@Z) already defined in ImageInRamCache.obj; second definition ignored 1>cachecontrol.obj : warning LNK4006: "bool __cdecl IntrinsicMultiplyInt64(__int64 const &,__int64 const &,__int64 *)" (?IntrinsicMultiplyInt64@@YA_NAEB_J0PEA_J@Z) already defined in ImageInRamCache.obj; second definition ignored While I understand I can ignore the error, I would like either (a) prevent the warning from occurring or (b) make it disappear so that my QA department doesn't flag it as a problem. And after spending some time researching it, I cannot find a way to do either.

    I've got VS2010 installed, I've downloaded the Windows Phone add-in and the Silverlight Toolkit from CodePlex, but I cannot work out for the life of me how to actually use the controls in a Windows Phone 7 application... How do I add the controls into the toolbox, or link them so that the XAML doesn't give me errors all the time? For instance, using the Viewbox - the controls aren't implemented, and the XAML does not compile.

  • C# Express 2010 Multi-Threading

    - by Chris Evans
    Hi, I have a windows app that I have been running in c# Express 2008 for a year and have been trying to convert it over the last few days to 2010. The problem I am having is it is a multi-threaded application that has to run a series of code every second. What it does is have a main thread, that calls 3 worker threads, waits for them to finish then does some additional processing, sleeps till 1 second and runs again. The problem is part of the code can call a web service that takes 8 seconds to respond, so this bit of code gets called using ThreadPool.QueueUserWorkItem. The problem is when running in 2010 when this part of the code gets called the main thread continues to run but when it awakens the sub threads it hangs until the Threadpool method finishes running. This never happens in 2008. Any suggestions? So far I put that bit of code in it's own thread rather than using Threadpool but same issue.
