  • Video Game Bots?

    - by cam
    Something I've always wondered, especially since it inspired me to start programming when I was a kid, was how video game bots work? I'm sure there are a lot of different methods, but what about automation for MMORPGs? Or even FPS-type bots?

  • Way to view Rails Migration output

    - by Ganesh Shankar
    Is there an easy way to see the actual SQL generated by a rails migration? I have a situation where a migration to change a column type worked on my local development machine by partially failed on the production server. My postgreSQL versions are different between local and production (7 on production, 8 on local) so I'm hoping by looking at the SQL generated on the successful migration locally I can work out a SQL statement to run on production to fix things....

  • Default template arguments for function templates

    - by Arman
    Why are default template arguments only allowed on class templates? Why can't we define a default type in a member function template? For example: struct mycclass { template<class T=int> void mymember(T* vec) { // ... } }; Instead, C++ forces that default template arguments are only allowed on a class template.

  • ASP MVC 2: Error with dropdownlist on POST

    - by wh0emPah
    Okay i'm new to asp mvc2 and i'm experiencing some problems with the htmlhelper called Html.dropdownlistfor(); I want to present the user a list of days in the week. And i want the selected item to be bound to my model. I have created this little class to generate a list of days + a short notation which i will use to store it in the database. public static class days { public static List<Day> getDayList() { List<Day> daylist = new List<Day>(); daylist.Add(new Day("Monday", "MO")); daylist.Add(new Day("Tuesday", "TU")); // I left the other days out return daylist; } public class Dag{ public string DayName{ get; set; } public string DayShortName { get; set; } public Dag(string name, string shortname) { this.DayName= name; this.DayShortName = shortname; } } } I really have now idea if this is the correct way to do it Then i putted this in my controller: SelectList _list = new SelectList(Days.getDayList(), "DayShortName", "DayName"); ViewData["days"] = _list; return View(""); I have this line in my model public string ChosenDay { get; set; } And this in my view to display the list: <div class="editor-field"> <%: Html.DropDownListFor(model => model.ChosenDay, ViewData["days"] as SelectList, "--choose Day--")%> </div> Now this all works perfect. On the first visit, But then when i'm doing a [HttpPost] Which looks like the following: [HttpPost] public ActionResult Registreer(EventRegistreerViewModel model) { // I removed some unrelated code here // The code below executes when modelstate.isvalid == false SelectList _list = new SelectList(Days.getDayList(), "DayShortName", "DayName"); ViewData["days"] = _list; return View(model); } Then i will have the following exception thrown: The ViewData item that has the key 'ChosenDay' is of type 'System.String' but must be of type 'IEnumerable<SelectListItem>'. This errors gets thrown at the line in my view where i display the dropdown list. I really have no idea how to solve this and tried several solutions i found online. but none of them really worked. Ty in advance!

  • boost::asio buffer impossible to convert parameter from char to const mutable_buffer&

    - by Ekyo777
    visual studio tells me "error C2664: 'boost::asio::mutable_buffer::mutable_buffer(const boost::asio::mutable_buffer&)': impossible to convert parameter 1 from 'char' to 'const boost::asio::mutable_buffer&' at line 163 of consuming_buffers.hpp" I am unsure of why this happen nor how to solve it(otherwise I wouldn't ask this ^^') but I think it could be related to those functions.. even tough I tried them in another project and everything worked fine... but I can hardly find what's different so... here comes code that could be relevant, if anything useful seems to be missing I'll be glad to send it. packets are all instances of this class. class CPacketBase { protected: const unsigned short _packet_type; const size_t _size; char* _data; public: CPacketBase(unsigned short packet_type, size_t size); ~CPacketBase(); size_t get_size(); const unsigned short& get_type(); virtual char* get(); virtual void set(char*); }; this sends a given packet template <typename Handler> void async_write(CPacketBase* packet, Handler handler) { std::string outbuf; outbuf.resize(packet->get_size()); outbuf = packet->get(); boost::asio::async_write( _socket , boost::asio::buffer(outbuf, packet->get_size()) , handler); } this enable reading packets and calls a function that decodes the packet's header(unsigned short) and resize the buffer to send it to another function that reads the real data from the packet template <typename Handler> void async_read(CPacketBase* packet, Handler handler) { void (CTCPConnection::*f)( const boost::system::error_code& , CPacketBase*, boost::tuple<Handler>) = &CTCPConnection::handle_read_header<Handler>; boost::asio::async_read(_socket, _buffer_data , boost::bind( f , this , boost::asio::placeholders::error , packet , boost::make_tuple(handler))); } and this is called by async_read once a packet is received template <typename Handler> void handle_read_header(const boost::system::error_code& error, CPacketBase* packet, boost::tuple<Handler> handler) { if (error) { boost::get<0>(handler)(error); } else { // Figures packet type unsigned short packet_type = *((unsigned short*) _buffer_data.c_str()); // create new packet according to type delete packet; ... // read packet's data _buffer_data.resize(packet->get_size()-2); // minus header size void (CTCPConnection::*f)( const boost::system::error_code& , CPacketBase*, boost::tuple<Handler>) = &CTCPConnection::handle_read_data<Handler>; boost::asio::async_read(_socket, _buffer_data , boost::bind( f , this , boost::asio::placeholders::error , packet , handler)); } }

  • jQuery tools modal overlay display problem in IE6-8

    - by Michael Stone
    I'm trying to enable the overlay to be modal. It works perfectly fine in FireFox, but the window object is behind the mask when it becomes modal. This prevents any interaction with it and the page is actually useless. I've tried debugging this for a while and can't figure it out. Here is a link to the example on their site: http://flowplayer.org/tools/demos/overlay/modal-dialog.html $.fn.cfwindow = function(btnEvent,modal,draggable){ //error checking if(btnEvent == ""){ alert('Error in window :\n Please provide an id that instantiates the window. '); } if(!modal && !draggable){ $('#'+btnEvent+'[rel]').overlay(); $('#content_overlay').css('cursor','default'); } if(!modal && draggable){ $('#'+btnEvent+'[rel]').overlay(); $('#content_overlay').css('cursor','move'); $('#custom').draggable(); } if(modal){ $('#'+btnEvent+'[rel]').overlay({ // some mask tweaks suitable for modal dialogs mask: { color: '#646464', loadSpeed: 200, opacity: 0.6 }, closeOnClick: false }); $('#content_overlay').css('cursor','default'); //$('#custom').addClass('modal'); } }; That's what I'm referencing when I call through: <script type="text/javascript"> $(document).ready(function(){ $(document).pngFix(); var modal = <cfoutput>#attributes.modal#; var drag = #attributes.draggable#; var btn = '#attributes.selector#'; var src = '#attributes.source#'; var wid = '#attributes.width#'; $('##custom').width(parseInt(wid)); $('div##load_content').load(src); $('##custom').cfwindow(btn,modal,drag,wid); }); </script> CSS for the modal: <style type="text/css"> .modal { display:none; text-align:left; background-color:#FFFFFF; -moz-border-radius:6px; -webkit-border-radius:6px; } </style> Exclude the and the additional pound signs, IE. "##". Screen shot of the problem: http://twitpic.com/1tak06 Note: IE6 and IE8 have the same problem. Any help would be appreciated.

  • When to address integer overflow in C

    - by Yktula
    Related question: http://stackoverflow.com/questions/199333/best-way-to-detect-integer-overflow-in-c-c In C code, should integer overflow be addressed whenever integers are added? It seems like pointers and array indexes should be checked at all. When should integer overflow be checked for? When numbers are added in C without type explicitly mentioned, or printed with printf, when will overflow occur? Is there a way to automatically detect when an integer arithmetic overflow?

  • Visual Studio Express 2012 debug mode doesn't work

    - by user2350086
    I have a project in Visual Studio that I have been working on for a while, and I have used the debugger extensively. Recently I changed some settings and I have lost the ability to stop the program and step through code. I can't figure out what I had changed that might have affected this. If I put a breakpoint in my code and try to have the program stop there, it doesn't. The break point shows up white with a red outline. If I hover the mouse over it, it says "The breakpoint will not currently be hit. No executable code of the debugger's target code type is associated with this line. Possible causes include: conditional compilation, compiler optimizations, or the target architecture of this line is not supported by the current debugger code type." I know for a fact that the program executes the code where the breakpoint is because I put the breakpoint in the beginning of the InitializeComponent method. The program displays the window fine, but does not stop at the breakpoint. Yes, I am running in debug mode. It seems as though there is a disconnect between the compiled code and the source code displayed. Does anyone know what that would be, or know which compiler settings I should check to re-enable debugging? Here are the compiler options: /GS /analyze- /W3 /Zc:wchar_t /I"D:\dev\libcurl-7.19.3-win32-ssl-msvc\include" /Zi /Od /sdl /Fd"Debug\vc110.pdb" /fp:precise /D "WIN32" /D "_DEBUG" /D "_UNICODE" /D "UNICODE" /errorReport:prompt /WX- /Zc:forScope /Oy- /clr /FU"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5\mscorlib.dll" /FU"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5\System.Data.dll" /FU"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5\System.dll" /FU"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5\System.Drawing.dll" /FU"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5\System.Windows.Forms.DataVisualization.dll" /FU"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5\System.Windows.Forms.dll" /FU"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5\System.Xml.dll" /MDd /Fa"Debug\" /EHa /nologo /Fo"Debug\" /Fp"Debug\Prog.pch" The linker options are: /OUT:"D:\dev\Prog\Debug\Prog.exe" /MANIFEST /NXCOMPAT /PDB:"D:\dev\Prog\Debug\Prog.pdb" /DYNAMICBASE "curllib.lib" "winmm.lib" "kernel32.lib" "user32.lib" "gdi32.lib" "winspool.lib" "comdlg32.lib" "advapi32.lib" "shell32.lib" "ole32.lib" "oleaut32.lib" "uuid.lib" "odbc32.lib" "odbccp32.lib" /FIXED:NO /DEBUG /MACHINE:X86 /ENTRY:"Main" /INCREMENTAL /PGD:"D:\dev\Prog\Debug\Prog.pgd" /SUBSYSTEM:WINDOWS /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /ManifestFile:"Debug\Prog.exe.intermediate.manifest" /ERRORREPORT:PROMPT /NOLOGO /LIBPATH:"D:\dev\libcurl-7.19.3-win32-ssl-msvc\lib\Debug" /ASSEMBLYDEBUG /TLBID:1

    - by mithun1538
    Hello everyone, I have a table called pollData. It will always contain only 1 row. It has columns option1, option2, option3, option4, option5 each of type int. In the beginning, these columns have 0 as their value. How do I add 1 to any column, say option2? I mean do i retrieve the value of that column first, perform addition, and store back, or is there any auto increment function?

  • XCode code generation

    - by Ali Shafai
    I was wondering if there is a tool (automator script or a third party) to generate code for simple scenarios like add another property. I don't like going to two or three places and write the same thing over and over again. instead I want to say "I want a new property of type int with name X" and it generates the lines in .h and .m files for me in one go.

  • Using embedded resources in Silverlight (4) - other cultures not being compiled

    - by Andrei Rinea
    I am having a bit of a hard time providing localized strings for the UI in a small Silverlight 4 application. Basically I've put a folder "Resources" and placed two resource files in it : Statuses.resx Statuses.ro.resx I do have an enum Statuses : public enum Statuses { None, Working } and a convertor : public class StatusToMessage : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { if (!Enum.IsDefined(typeof(Status), value)) { throw new ArgumentOutOfRangeException("value"); } var x = Statuses.None; return Statuses.ResourceManager.GetString(((Status)value).ToString(), Thread.CurrentThread.CurrentUICulture); } public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { throw new NotImplementedException(); } } in the view I have a textblock : <TextBlock Grid.Column="3" Text="{Binding Status, Converter={StaticResource StatusToMessage}}" /> Upon view rendering the converter is called but no matter what the Thread.CurrentThread.CurrentUICulture is set it always returns the default culture value. Upon further inspection I took apart the XAP resulted file, taken the resulted DLL file to Reflector and inspected the embedded resources. It only contains the default resource!! Going back to the two resource files I am now inspecting their properties : Build action : Embedded Resource Copy to output directory : Do not copy Custom tool : ResXFileCodeGenerator Custom tool namespace : [empty] Both resource (.resx) files have these settings. The .Designer.cs resulted files are as follows : Statuses.Designer.cs : //------------------------------------------------------------------------------ // <auto-generated> // This code was generated by a tool. // Runtime Version:4.0.30319.1 // // Changes to this file may cause incorrect behavior and will be lost if // the code is regenerated. // </auto-generated> //------------------------------------------------------------------------------ namespace SilverlightApplication5.Resources { using System; /// <summary> /// A strongly-typed resource class, for looking up localized strings, etc. /// </summary> // This class was auto-generated by the StronglyTypedResourceBuilder // class via a tool like ResGen or Visual Studio. // To add or remove a member, edit your .ResX file then rerun ResGen // with the /str option, or rebuild your VS project. [global::System.CodeDom.Compiler.GeneratedCodeAttribute("System.Resources.Tools.StronglyTypedResourceBuilder", "4.0.0.0")] [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] [global::System.Runtime.CompilerServices.CompilerGeneratedAttribute()] internal class Statuses { // ... yadda-yadda Statuses.ro.Designer.cs [empty] I've taken both files and put them in a console application and they behave as expected in it, not like in this silverlight application. What is wrong?

  • Inline-editing: onBlur prevents onClick from being triggered (jQuery)

    - by codethief
    Hello StackOverflow community! I'm currently working on my own jQuery plugin for inline-editing as those that already exist don't fit my needs. Anyway, I'd like to give the user the following (boolean) options concerning the way editing is supposed to work: submit_button reset_on_blur Let's say the user would like to have a submit button (submit_button = true) and wants the inline input element to be removed as soon as it loses focus (reset_on_blur = true). This leads to an onClick handler being registered for the button and an onBlur handler being registered for the input element. Every time the user clicks the button, however, the onBlur handler is also triggered and results in the edit mode being left, i.e. before the onClick event occurs. This makes submitting impossible. FYI, the HTML in edit mode looks like this: <td><input type="text" class="ie-input" value="Current value" /><div class="ie-content-backup" style="display: none;">Backup Value</div><input type="submit" class="ie-button-submit" value="Save" /></td> So, is there any way I could check in the onBlur handler if the focus was lost while activating the submit button, so that edit mode isn't left before the submit button's onClick event is triggered? I've also tried to register a $('body').click() handler to simulate blur and to be able to trace back which element has been clicked, but that didn't work either and resulted in rather strange bugs: $('html').click(function(e) { // body doesn't span over full page height, use html instead // Don't reset if the submit button, the input element itself or the element to be edited inline was clicked. if(!$(e.target).hasClass('ie-button-submit') && !$(e.target).hasClass('ie-input') && $(e.target).get(0) != element.get(0)) { cancel(element); } }); jEditable uses the following piece of code. I don't like this approach, though, because of the delay. Let alone I don't even understand why this works. ;) input.blur(function(e) { /* prevent canceling if submit was clicked */ t = setTimeout(function() { reset.apply(form, [settings, self]); }, 500); }); Thanks in advance!

  • Implementing PyMyType_Check methods with Python C API?

    - by Paul D.
    All the Python-provided types have a check method (i.e., PyList_Check) that allows you to check if an arbitrary PyObject* is actually a specific type. How can I implement this for my own types? I haven't found anything good online for this, though it seems like a pretty normal thing to want to do. Also, maybe I'm just terrible at looking through large source trees, but I cannot for the life of me find the implementation of PyList_Check or any of it's companions in the Python (2.5) source.
