  • Svn log - svn: '.' is not a working copy

    - by fampinheiro
    I'm getting "svn: '.' is not a working copy" when i use the svn log command. I know that i need a working copy for the log command to work but can this be done directly on a repository? My goal is to display the information (change history) of a repository. I think updating the working copy whenever i need the log information is not a good solution. Is there an alternative solution to this or updating a working copy every time i need to log is the only way to go? Thanks in advance.

  • Nested Functions in C - Best Practices

    - by Justin Ethier
    I just realized a function may be defined inside another function in C: void main(){ int foo(){ return 2; }; printf("%d\n", foo()); } Besides being a neat trick, the useful thing about this is that the inner function is private to the outer function. But... is that a good enough reason to do this in a "real-world" application? What are the best practices for using this syntax?

  • Finding a pattern within a string variable in C#

    - by lo3
    Ok i'm working on a project for a 200 level C# course, we are required to create a heads or tails project. Basically the project is setup so that the computer will guess randomly up to 5 times, but on the sixth time it will look into the playersGuessHistory variable setup as a string to see if it can find a match for a pattern of 4 entires, if there is a pattern found the computer will guess the next character after the pattern EX: [HHTT]H [HHTTH]H HHTT being the pattern then the computer would guess H for the next turn. My only problem is that i'm having difficulty setting up the project so that it will look through the playersguesshistory and find the patterns and guess the next character in the history. Any suggestions?

  • Composite operations in Android Canvas

    - by kayahr
    I'm just starting with Android development and I'm coming from JavaScript/HTML world so I'm currently investigating the possibilities of the Android SDK. The HTML 5 canvas supports composite operations (See here). Is this possible in an Android Canvas? I scanned the API of the Canvas class but couldn't find anything useful. I need at least the composite operation "source-in" or (if this isn't possible) "source-atop".

  • Combining Hg Commits Before Pushing?

    - by Rob
    Let's say I am working on a feature branch cloned from an hg repository - I make some commits and then push the changes back to the repository as expected. However, is there any way to combine multiple commits into a single changeset for the push? For example, today I committed some changes and then remembered I hadn't updated the README file - which meant a 'single' set of changes actually consisted of 2 commits to my local repository. When I pushed these changes back to the original repository it would of been useful to combine the two as a single entity to save cluttering up the repository history.

  • Turing-Complete language possibilities?

    - by I can't tell you my name.
    In every Turing-Complete language, is it possible to create a working Compiler for itself which first runs on an interpreter written in some other language and then compiles it's own source code? (Bootstrapping) Standards-Compilant C++ compiler which outputs binaries for, e.g.: Windows? Regex Parser and Evaluater? World of Warcraft clone? (Assuming the language gets the necessary API bindings as, for example, OpenGL and the WoW source code is available) (Everything here theoretical) Let's take Brainf*ck as an example language.

  • VS2008 C++ MFC Access Violation ONLY when stepping through debug mode

    - by HotOil
    Hi. This is crazy. It started happening in my main project, so I created a tiny sample brand-new project to reproduce it in and sure enough.. It does NOT happen in a sample project I created that is only a Win32 console app. I'm running this on Win7x64, if that matters. VS2008 SP1. Here goes. I create a small dialog app with a button. Put a breakpoint in the handler function for that button. The button handler function looks like this: void CTestProjectDlg::OnBnClickedButton1() { int i=2; m_csHello.Format(_T("Hello World!")); << breakpoint here UpdateData(FALSE); } Click the button, hit the breakpoint. F10 to step, and boom: "First-chance exception at 0x0398f77b in TestProject.exe: 0xC0000005: Access violation." It gives me the option to Break or Continue. If I Continue, it just hits it again, only not "First Chance". Yes I have that exception checked in the Debug-Exceptions dlg. If I Break, the call stack just shows me the line where the breakpoint is. If I F10 again.. I get the exception again, only now the callstack shows me in the _AfxDispatchCmdMsg() function, and my original OnBnClickedButton1() is not in the callstack anymore. It doesn't matter where I put the breakpoint. If, instead of F10, I just continue with F5, it works normally. Now.. if I build a Release version and run in debugging mode: I hit the breakpoint, and all the pointers, variable values look normal. F10, and these turn to garbage. The this pointer is now zero. The m_csHello is now However, in Release mode, an exception is not caught, and it all runs fine. The "hello World string gets displayed in the dialog box as it should. I have put in an inquiry to see if some patch was installed on my box by the IT dept in the last day or two. This wasn't happening 2 days ago. What do you think? Is VS2008 corrupted? Thanks.

  • What is a postback?

    - by Scott Saad
    I'm making my way into web development and have seen the word postback thrown around. Coming from a non-web based background, what does a new web developer have to know about postbacks? (i.e. what are they and when do they arise?) Any more information you'd like to share to help a newbie in the web world be aware of postbacks would be most greatly appreciated.

  • DB2 - How to run an ad hoc select query with a parameter in IBM System i Access for Windows GUI Tool

    - by KenB
    I would like to run some ad hoc select statements in the IBM System I Navigator tool for DB2 using a variable that I declare. For example, in the SQL Server world I would easily do this in the SQL Server Management Studio query window like so: DECLARE @VariableName varchar(50); SET @VariableName = 'blah blah'; select * from TableName where Column = @VariableName; How can I do something similar in the IBM System I Navigator tool?

  • Retro video games programming

What about the OS for the video games consoles? Are there any website with resources about this subject? (I am a 90s video gamer so I am particularly interested about the programming behind those games but feel free to make this a wiki and include links to resources about video games programming in general, if you want)

  • Is Microformat's date-value-pattern fully accessible?

    - by Stephen
    Has there been an announcement (outside microformats.org) that the value-class-pattern is fully accessible? e.g. given <abbr class="value" title="2008-06-24">this Tuesday</abbr>, will a screen reader say "24 June 2008" or will it say "2008 dash 6 dash 24"? History Microformats came along, and were great, except that dates etc were stored in abbr tags: <abbr class="dtstart" title="20070312T1700-06"> March 12, 2007 at 5 PM, Central Standard Time </abbr>` This lead to screen readers doing ridiculous things as noted in hAccessibility. Now that microformats.org have released the value-class-pattern it's a lot better. But I'm left unable to find a declaration from WaSP (or another accessibility source not directly tied to microformats) that declaratively states that they are now accessible to screen readers etc.

  • Babel Obfuscator: Sample effective post build event for free version

    - by JL
    Does anyone have a sample post build event for Babel Obfuscator I can just copy and paste into my .net assembly release build configuration? The documentation for Babel is 54 pages long, and unfortunately doesn't come with any real world samples on how to use it with Visual Studio integration. Failing that , is there a free obfuscator out there that integrates well with VS 2008 post build, so that it will obfuscate the release DLL during each new build. I was using Eazfuscator which broke since they released version 2.8. Thank you

  • NUnit vs Visual Studio 2010's MSTest?

    - by David White
    I realise that there are many older questions addressing the general question of NUnit v MSTest for versions of Visual Studio up to 2008 (such as this one). Microsoft have a history of getting things right in their 3rd version. For MSTest, that is VS2010. Have they done so with MSTest? Would you use it in a new project in preference to NUnit? My specific concerns: speed running tests within CruiseControl.NET (either commandline or MSBuild task) code coverage reports from CC.NET can you run MSTest tests in debug mode (We use ReSharper, so test-runners are not an issue for us. We have used NUnit for the last few years. We do not have TFS.)
