• Is there any reason to use TFS 2010 in a micro ISV?

  - by kyrisu

  Yesterday I was checking VS2010 editions here and I've noticed that with VS10 with MSDN we get TFS2010 with 1 CAL. I'm a micro ISV (basically sole developer, many clients). I just want to save time - did anyone tried it in similar scenario? Are there any features worth looking into for such a small implementation? P.S. Right now I'm using GIT with gitextension - I'm happy with it, but I would like something more integrated with project management and bug tracking so I can show it to my clients when I'm working on their projects.

• How do you get Eclipse/Mylyn to fill out your commit messages for you?

  - by Sam Hasler

  I've setup the following: Installed Mylyn in Eclipse Installed the Bugzilla connector Installed Subversive SVN Integration for the Mylyn Project I've gone to Windows - Preferences - Tasks - Team and clicked Change Set Management and left it with the default Commit Comment Template: ${task.status} - ${connector.task.prefix} ${task.key}: ${task.description} ${task.url} However, if I activate a bugzilla bug in the Task List, and then edit a file, when I commit the changes the commit message isn't filled in. Also, in the Synchronisation perspective there isn't a change set for the task I'm working on. I've tried following the instructions on the Eclipse wiki's Mylyn FAQ for Why does task change set not appear when I modify files? but the bullet point: * Verify that the configured Synchronize View is configured for change sets. points to a section that is no longer in the document. I have a Show Change Sets button, but clicking it only shows me incoming change sets, there aren't any outgoing change sets. What am I missing?

• OutOfMemoryError calling XmlSerializer.Deserialize() - not related to XML size!

  - by Mike Atlas

  This is a really crazy bug. The following is throwing an OutOfMemoryException, for XML snippits that are very short (e.g., <ABC def='123'/>) of one type, but not for others of the same size but a different type: (e.g., <ZYX qpr='baz'/>). public static T DeserializeXmlNode<T>(XmlNode node) { try { return (T)new XmlSerializer(typeof(T)) .Deserialize(new XmlNodeReader(node)); } catch (Exception ex) { throw; // just for catching a breakpoint. } } I read in this MSDN article that if I were using XmlSerializer with additional parameters in the constructor, I'd end up generating un-cached serializer assemblies every it got called, causing an Assembly Leak. But I'm not using additional parameters in the constructor. It also happens on the first call, too, so the AppDomain is fresh. Worse yet, it is only thrown in release builds, not debug builds. What gives?

• Mapped Stored Procedures in EF 1

  - by michael.lukatchik

  All, I'm using mapped Stored Procedures in EF 1. I've completed the following steps: 1) I've created my INSERT, UPDATE, and DELETE queries in SQL Server. 2) I've built the EDMX and imported the INSERT, UPDATE, and DELETE sprocs as part of my model. 3) I've set up a Stored Procedure Mapping on a table inside of my EDMX file. The INSERT, UPDATE, and DELETE sprocs were mapped accordingly. Using this approach, I would expect to rebuild the application (and mine builds successfully) and then see the Stored Procedures as available function names via my EDMX object, such as: _entities.InsertComment(..), _entities.UpdateComment(..), and _entities.DeleteComment(..) Intellisense is not picking these names up and I can't figure out why. If I perform these same steps using EF4, the function names are automatically picked up by Intellisense after adding the Stored Procedure Mappings. Is this a bug in EF1? Is there something else I should be doing? Thanks in advance, Mike

• "Socket operation on non-socket" error due to strange syntax

  - by Robert S. Barnes

  I ran across the error Socket operation on non-socket in some of my networking code when calling connect and spent a lot of time trying to figure out what was causing it. I finally figured out that the following line of code was causing the problem: if ((sockfd = socket( ai->ai_family, ai->ai_socktype, ai->ai_protocol) < 0)) { See the problem? Here's what the line should look like: if ((sockfd = socket( ai->ai_family, ai->ai_socktype, ai->ai_protocol)) < 0) { What I don't understand is why the first, incorrect line doesn't produce a warning. To put it another way, shouldn't the general form: if ( foo = bar() < baz ) do_something(); look odd to the compiler, especially running with g++ -Wall -Wextra? If not, shouldn't it at least show up as "bad style" to cppcheck, which I'm also running as part of my compile?

• How to take a screenshot with Mono C#?

  - by vagabond

  I'm trying to use use code get a screenshot in Mono C# but I'm getting a System.NotImplementedException when I call CopyFromScreen. My code works with .NET, so is there an alternate way of getting a screenshot using Mono?

• how to compile a program with gtkmozembed.h

  - by ganapati hegde

  Hi, i have written a program under ubuntu, in which i include gtkmozembed.h. I am facing a problem in compiling the program.Below is the simplest form of a program which uses gtkmozembed. #include <gtk/gtk.h> #include <stdio.h> #include <gtkmozembed.h> int main(){ GtkWidget *mozEmbed; mozEmbed = gtk_moz_embed_new(); return 0; } Eventhough, the above program is doing nothing, compiling that program is a lot for me... I am trying to comile the above program like below gcc `pkg-config --libs --cflags gtk+-2.0` test.c -o test and it is giving the following error... error: gtkmozembed.h: No such file or directory I can understand, something else has to be added to the above gcc line,so that the compiler can find the gtkmozembed.h, but not getting what is that, 'something'...Looking for someone's help..Thank you...

• implicit parameter definition in class

  - by coubeatczech

  implicit val odkaz = head; def vypis(implicit odkaz:Prvek):String = { odkaz match{ case null => "" case e => e.cislo + " " + e.pocet + "\n" + vypis(e.dalsi) } } ... def main(args:Array[String]){ val q = new MyQueue() // insert some values println(q.vypis) } This method(vypis) is a member of an queue-class so I'll always want to implicity start the recursion from the start of the queue, when calling the method from outside. Is there a way how to write it, that the method from outside calling, there's no paramter, but in inside, there's a parameter - for recursion...? The compiler complains that the parameter is not defined when called from outside

• ESS/AucTeX/Sweave integration

  - by aL3xa

  I'm using GNU/Linux distro (Arch, if that's relevant), Emacs v23.2.1, ESS v5.9 and AucTeX v11.86. I want to setup AucTeX to recognize .Rnw files, so I can run LaTeX on .Rnw files with C-c C-c and get .dvi file automatically. I reckon it's quite manageable by editing .emacs file, but I still haven't got a firm grasp on Elisp. Yet another problem is quite annoying - somehow, LaTeX is not recognizing \usepackage{Sweave} in preambule, so I actually need to copy Sweave.sty file (in my case located in /usr/share/R/texmf/Sweave.sty) to directory where .Rnw file is located (and I'm getting more frustrated with the fact that this is common bug on Windows platforms!) My question boils down to two problems: how to make LaTeX recognize \usepackage{Sweave} (without copying Sweave.sty to "home" folder each time) how to setup AucTeX to compile .Rnw files to .dvi

• Globbing with MinGW on Windows

  - by Neil Butterworth

  I have an application built with the MinGW C++ compiler that works something like grep - acommand looks something like this: myapp -e '.*' *.txt where the thing that comes after the -e switch is a regex, and the thing after that is file name pattern. It seems that MinGW automatically expands (globs in UNIX terms) the command line so my regex gets mangled. I can turn this behaviour off, I discovered, by setting the global variable _CRT_glob to zero. This will be fine for bash and other sensible shell users, as the shell will expand the file pattern. For MS cmd.exe users however, it looks like I will have to expand the file pattern myself. So my question - does anyone know of a globbing library (or facility in MinGW) to do partial command line expansion? I'm aware of the _setargv feature of the Windows CRT, but that expands the full command line. Please note I've seen this question, but it really does not address partial expansion.

• v8 is too slow for my purpose

  - by Scott

  I'm working on a music visualization plugin for libvisual. It's an AVS clone -- AVS being from Winamp. Right now I have a superscope plugin. This element has 4 scripts, and "point" is run at every pixel. You can imagine that it has to be rather fast. The original libvisual avs clone had a JIT compiler that was really fast, but it had some bugs and wasn't fully implemented, so I decided to try v8. Well, v8 is too slow running the compiled script at every pixel. Is there any other script engine that would be pretty fast for this purpose?

• Question about member function pointers in a heirarchy

  - by Jesse Beder

  I'm using a library that defines an interface: template<class desttype> void connect(desttype* pclass, void (desttype::*pmemfun)()); and I have a small heirarchy class base { void foo(); }; class derived: public base { ... }; In a member function of derived, I want to call connect(this, &derived::foo); but it seems that &derived::foo is actually a member function pointer of base; gcc spits out error: no matching function for call to ‘connect(derived* const&, void (base::* const&)())’ I can get around this by explicitly casting this to base *; but why can't the compiler match the call with desttype = base (since derived * can be implicitly cast to base *)? Also, why is &derived::foo not a member function pointer of derived?

• Essential Programming Tools

  - by Mat

  We all have different needs due to the platform and/or stack we work with, and simple programmer preference is famous for starting religious wars. However, in each area there is usually a set of tools that get recommended over and over, even though people might individually prefer one member over the others. Unix text mode code editors, for example, is an extremely contentious issue but no one can deny that most people will choose either vi or emacs. So, without criticising the alternatives, recommend me developement tools. Text editors for different platforms, version control systems, bug trackers, database engines, templating systems... whatever! What do you enjoy using every day? I'll edit together the answers as a list of highly recommended tools in each area. Please don't start discussing which is the best ;)

• pgf/tikz: String Symbols as Input Coordinates

  - by red_lynx

  Hi all, I'm new to pgf so i was trying out some examples from the pgfplot manual. One example is especially relevant for my current task but, alas, it would not compile. Here is the code: \documentclass[11pt]{article} \usepackage{tikz} \usepackage{pgfplots} \begin{document} \begin{tikzpicture} \begin{axis}[symbolic x coords={a,b,c,d,e,f,g,h,i}] \addplot+[smooth] coordinates { (a,42) (b,50) (c,80) (f,60) (g,62) (i,90)}; \end{axis} \end{tikzpicture} \end{document} the compiler quits with the following error: ! Package PGF Math Error: Could not parse input 'a' as a floating point number, sorry. The unreadable part was near 'a'.. I have no clue how to correct this behavior. Other plots (smooth, scatter, bar), which contain only numerical data compile fine. Could anybody give me a hint? Cheers K.

• Which is better for quickly developing small utilities? AutoIt or AutoHotKey?

  - by Abhijeet Pathak

  Which is better for quickly developing small utilities? AutoIt or AutoHotKey or something else? I need to develop some small software for which I think using some professional suite like Visual Studio will be overkill. Most of the macro recording tools like AutoIt or AutoHotKey provide enough power to write decent application. Plus they are small and free. Which option will be good? Using one of these tools or using some other small/free compiler?

• WebConfigurationManager error after adding siteMap

  Hello I'm getting this error: Compiler Error Message: CS0118: 'Configuration' is a 'namespace' but is used like a 'type' Configuration myWebConfig = WebConfigurationManager.OpenWebConfiguration("~/"); This code has been in place for 5+ months without this issues, only today after adding this sitemap code do I have this issue. <siteMap defaultProvider="ExtendedSiteMapProvider" enabled="true"> <providers> <clear/> <add name="ExtendedSiteMapProvider" type="Configuration.ExtendedSiteMapProvider" siteMapFile="Web.sitemap" securityTrimmingEnabled="true"/> </providers> </siteMap> I tried adding "System.Web." before the "Configuration ", but that did not work either: System.Web.Configuration myWebConfig = WebConfigurationManager.OpenWebConfiguration("~/"); Error 1 'System.Web.Configuration' is a 'namespace' but is used like a 'type'

• Cmake suddenly can't find my source files anymore...

  - by aheld

  To make a long story short: To add insult to injury, CMake actually ran fine several times. I was wrestling with a compiler error when CMake suddenly didn't feel like working anymore. For reference, here's the whole CMakeLists.txt file: set(CMAKE_INCLUDE_CURRENT_DIR ON) Find_Package ( SDL REQUIRED ) Find_Package ( SDL_image REQUIRED ) Find_Package ( SDL_mixer REQUIRED ) if ( NOT SDL_FOUND ) message ( FATAL_ERROR "Make sure that SDL is installed" ) endif ( NOT SDL_FOUND ) link_libraries ( ${SDL_LIBRARY} ${SDLIMAGE_LIBRARY} ${SDLMIXER_LIBRARY} SDLmain ) set(wiggle_SOURCES level.cpp levelgenerator.cpp main.cpp player.cpp scoreboard.cpp snake.cpp soundplayer.cpp titlescreen.cpp ) add_executable(Wiggle ../${wiggle_SOURCES}) The error occured for the first time when, instead of simply typing "make", I typed "make -lSDL -lSDL_image -lSDL_mixer" - make refused to find the header files SDL.h and SDL_image.h after I detached the project from Code::Blocks.

• macdeployqt and third party libraries

  - by user338170

  I've got an application project that depends on a couple of shared libraries that I have created myself. According to the Qt 4.6 documentation "Deploying an Application on Mac OSX": Note: If you want a 3rd party library to be included in your application bundle, then you must add an excplicit lib entry for that library to your application's .pro file. Otherwise, the macdeployqt tool will not copy the 3rd party .dylib into the bundle. I have added lib entries to my application's .pro file but the libraries that I have written do not get copied into the bundle when I execute macdeployqt. I have the following in my .pro file: LIBS += -L../Libraries -lMyLib Everything builds okay, its just when I try to run from the bundle that I run into problems i.e. "image not found" errors. Is there a bug in macdeployqt or do I have to something more to my .pro file?

• How have popular iPhone games been ported to Android?

  - by Cirrostratus

  I am not asking how could they have been, I want to know the real answer. Doodle Jump, Paper Toss and some others have versions on the iPhone and Android that are nearly exactly the same, with the iPhone version coming first. There is a small Objective-C compiler project for Android's NDK but the timing isn't right for these apps. There's also an Android port of Cocos2d but I doubt Doodle Jump used that. Titanium? Doubtful. As their respective code bases grow, I figure it'd get harder and harder to do an exact port from Objective-C to Java every release so I wonder if there is a better way. Are they sharing C++ code for example?

• New asp "showat" attribute required inconsistently in VS2010. Why?

  - by Patrick Karcher

  When I generate code using T4 templates in Visual Studio 2010, I get the following error for each of my asp controls when I try to compile: Control "ddState" is missing required attribute "showat". I have never gotten this error in previous versions of .NET. Further, I don't get this error when I manually construct my pages either by dragging/dropping, nor do I get it when I type out the control text myself. When I generate code, I have to manually add showat="client" to my tag for the compiler to be happy. It was my understanding that I never had to explicitly specify this tag. The following: <asp:dropdownlist id="ddState" runat="server" showat="client" /> solves the problem. Why do I have to add this to generated code but not other times? (It's a VS-2010 webforms project, using VB, in case that makes a difference.)

• Why do I get Code Analysis CA1062 on an out parameter in this code?

  - by brickner

  I have a very simple code (simplified from the original code - so I know it's not a very clever code) that when I compile in Visual Studio 2010 with Code Analysis gives me warning CA1062: Validate arguments of public methods. public class Foo { protected static void Bar(out int[] x) { x = new int[1]; for (int i = 0; i != 1; ++i) x[i] = 1; } } The warning I get: CA1062 : Microsoft.Design : In externally visible method 'Foo.Bar(out int[])', validate local variable '(*x)', which was reassigned from parameter 'x', before using it. I don't understand why do I get this warning and how can I resolve it without suppressing it? Can new return null? Is this a Visual Studio 2010 bug?

• Slime in emacs seems has conflicts with autopair

  - by Boris

  I have just install slime in emacs. And after removed all the other plugins for debuging, I found that slime seems had conflicts with autopair.(Or a bug of autopair?).In slime, when I typed C-c C-c, the minibuffer displayed error like: error in process filter: define-key: Wrong type argument: characterp, nil error in process filter: Wrong type argument: characterp, nil error in process filter: define-key: Wrong type argument: characterp, nil error in process filter: Wrong type argument: characterp, nil Even more, the error message still alerted after I killed the slime buffer. If I also remove the autopair plugin, slime works just fine. Can anyone tell me how to solve this? Thanks. :)

• Choosing Merge Direction

  - by tbreffni

  Consider a simple source-control layout, with a trunk representing a future release in development and a single branch representing a release currently in production. When a bug is discovered that needs fixed in both branches, should the change be made first to the trunk then merged down to the branch, or made first to the branch then merged up to the trunk? Typically I've made the fix first in the trunk then merged downwards, however there is an increased risk this way that future new features get merged down accidentally. What has worked best in your experience?

• Is it possible to have a Ocaml function that accepts only integer lists?

  - by Sam

  I'm writing a recursive function in Ocaml that's supposed to count the number of items in an integer list (Yes I know there's a List.length function but I'm trying to do it myself). However the Ocaml compiler/interpreter forces me to use alpha list all the time. So is it wrong to say that, when a function accepts a list as a parameter, the type of that list must always be alpha? Thanks EDIT: the reason why it's inconvenient for me to use alpha lists is because i can't compare the head of the alpha list with an integer value due to type-matching complaints

• In Applescript, why do local variables in handlers capture "with" labeled parameters?

  - by outis

  In Applescript, if you declare a handler using "with" labeled parameters, local variables get the values of the arguments and the parameters themselves are undefined. For example: on bam of thing with frst and scnd local eat_frst return {thing: thing, frst:frst, scnd:scnd} -- this line throws an error end bam bam of "bug-AWWK!" with frst without scnd results in an error message that "scnd" isn't defined in the second line of bam. thing and frst are both defined, getting the arguments passed in the call to bam. Why is this happening? Why is scnd undefined? Note: I know that declaring variables as "local" within a handler is unnecessary. It's done in the examples for illustrative purposes.
