  • A question about John Resig's Simple Javascript Inheritance.

    - by Zippo
    I'm using this simple code: http://ejohn.org/blog/simple-javascript-inheritance/ Using this "library", I made this simple class: var Person = Class.extend({ init: function(openningSentence) { this.say(openningSentence); }, say: function(words) { alert(words); } }); The problem with this class, is that I can't call a function using the variable "this" (line 3 in the code gives an error: unknown method "say"). Does anybody knoes if there's a solution for this problem? Btw - I'm using jquery, so if there's a jquery-based solution It'll be great :)

    - by ame
    I have this code written in MFC as a win32 application: CZoneThread* pThread = new CZoneThread( sZoneInfo ); pThread-CreateThread(); Here, CZoneThread is another class. Will this code work correctly in WinCE as well?

  • MediaWiki migrated from Tiger to Snow Leopard throwing an exceptions

    - by Matt S
    I had an old laptop running Mac OS X 10.4 with macports for web development: Apache 2, PHP 5.3.2, Mysql 5, etc. I got a new laptop running Mac OS X 10.6 and installed macports. I installed the same web development apps: Apache 2, PHP 5.3.2, Mysql 5, etc. All versions the same as my old laptop. A Mediawiki site (version 1.15) was copied over from my old system (via the Migration Assistant). Having a fresh Mysql setup, I dumped my old database and imported it on the new system. When I try to browse to mediawiki's "Special" pages, I get the following exception thrown: Invalid language code requested Backtrace: #0 /languages/Language.php(2539): Language::loadLocalisation(NULL) #1 /includes/MessageCache.php(846): Language::getFallbackFor(NULL) #2 /includes/MessageCache.php(821): MessageCache->processMessagesArray(Array, NULL) #3 /includes/GlobalFunctions.php(2901): MessageCache->loadMessagesFile('/Users/matt/Sit...', false) #4 /extensions/OpenID/OpenID.setup.php(181): wfLoadExtensionMessages('OpenID') #5 [internal function]: OpenIDLocalizedPageName(Array, 'en') #6 /includes/Hooks.php(117): call_user_func_array('OpenIDLocalized...', Array) #7 /languages/Language.php(1851): wfRunHooks('LanguageGetSpec...', Array) #8 /includes/SpecialPage.php(240): Language->getSpecialPageAliases() #9 /includes/SpecialPage.php(262): SpecialPage::initAliasList() #10 /includes/SpecialPage.php(406): SpecialPage::resolveAlias('UserLogin') #11 /includes/SpecialPage.php(507): SpecialPage::getPageByAlias('UserLogin') #12 /includes/Wiki.php(229): SpecialPage::executePath(Object(Title)) #13 /includes/Wiki.php(59): MediaWiki->initializeSpecialCases(Object(Title), Object(OutputPage), Object(WebRequest)) #14 /index.php(116): MediaWiki->initialize(Object(Title), NULL, Object(OutputPage), Object(User), Object(WebRequest)) #15 {main} I tried to step through Mediawiki's code, but it's a mess. There are global variables everywhere. If I change the code slightly to get around the exception, the page comes up blank and there are no errors (implying there are multiple problems). Anyone else get Mediawiki 1.15 working on OS X 10.6 with macports? Anything in the migration from Tiger that could cause a problem? Any clues where to look for answers?

  • How do I increase the buffer size for domain sockets in OS X 10.6

    - by Chas. Owens
    In Linux I have no problem dumping tons of data into a domain socket, but the same code on OS X 10.6.2 blows up after about 65 records. The socket reader code looks like #!/usr/bin/perl use strict; use warnings; use IO::Socket; unlink "foo"; my $sock = IO::Socket::UNIX->new ( Local => 'foo', Type => SOCK_DGRAM, Timeout => 600, ) or die "Could not create socket: $!\n"; while (<$sock>) { chomp; print "[$_]\n"; } And the client code looks like #!/usr/bin/perl use strict; use warnings; use IO::Socket; my $sock = IO::Socket::UNIX->new ( Peer => 'foo', Type => SOCK_DGRAM, Timeout => 600, ) or die "Could not create socket: $!\n"; for my $i (1 .. 1_000_000) { print $sock "$i\n" or die $!; } close $sock; The error message I get is No buffer space available at write.pl line 15.. It seems fairly obvious that there is a difference in the buffer size between Linux and OS X, but I don't know how to set it OS X (or what the possible negative side effects might be).

  • When is #include <new> library required in C++?

    - by Czarak
    Hi, According to this reference entry for operator new ( http://www.cplusplus.com/reference/std/new/operator%20new/ ) : Global dynamic storage operator functions are special in the standard library: All three versions of operator new are declared in the global namespace, not in the std namespace. The first and second versions are implicitly declared in every translation unit of a C++ program: The header does not need to be included for them to be present. This seems to me to imply that the third version of operator new (placement new) is not implicitly declared in every translation unit of a C++ program and the header <new> does need to be included for it to be present. Is that correct? If so, how is it that using both g++ and MS VC++ Express compilers it seems I can compile code using the third version of new without #include <new> in my source code? Also, the MSDN Standard C++ Library reference entry on operator new gives some example code for the three forms of operator new which contains the #include <new> statement, however the example seems to compile and run just the same for me without this include? // new_op_new.cpp // compile with: /EHsc #include<new> #include<iostream> using namespace std; class MyClass { public: MyClass( ) { cout << "Construction MyClass." << this << endl; }; ~MyClass( ) { imember = 0; cout << "Destructing MyClass." << this << endl; }; int imember; }; int main( ) { // The first form of new delete MyClass* fPtr = new MyClass; delete fPtr; // The second form of new delete char x[sizeof( MyClass )]; MyClass* fPtr2 = new( &x[0] ) MyClass; fPtr2 -> ~MyClass(); cout << "The address of x[0] is : " << ( void* )&x[0] << endl; // The third form of new delete MyClass* fPtr3 = new( nothrow ) MyClass; delete fPtr3; } Could anyone shed some light on this and when and why you might need to #include <new> - maybe some example code that will not compile without #include <new> ? Thanks.

  • GPL liscensed frameworks on eccommerce websites

    - by Adam McMahon
    Ok this may be a foolish question, but I just want some clarification on this. If you build a website on a GPL licensed web framework, let's say a browser based game or some kind of kind of sophisticated web application are you required to redistribute all the code? If this is so what licenses would allow you to build on top of an opensource project without requiring you to redistribute the code?

  • Mix Enviroment Debugging ( C# Fortran) in VS 2008

    - by Ngu Soon Hui
    I have two visual studio projects, one written in C#, another written in fortran unmanaged code ( Intel Fortran compiler). Both of them are attached to one solution. The C# is the frontend winform, whereas the fortran project is the backend. Is there any tutorials that teach on how to step into code direct from C#?

  • Grails withCriteria testing

    - by Steve Wall
    Hello, I'd like to test a "withCriteria" closure and am not sure how to go about it. I see how to mock out the withCriteria call, but not test the code within the closure. When running the test that executes the "withCriteria", I keep getting a MissingMethodException, even though the code runs fine under the normal flow of execution. Any ideas? Thanks! Steve

  • passing multiple vectors to function by reference (using structure)

    - by madman
    Hi StackOverflow, Can someone tell me the correct way of passing multiple vectors to a function that can take only a single argument? (specifically for pthread_create (..) function) I tried the following but it does not seem to work :-( First, I created the following structure struct ip2 { void* obj; int dim; int n_s; vector<vector<vector<double> > > *wlist; vector<int> *nrsv; struct model *pModel; }; The threads that I have created actually needs all these parameters. Since im using pthreads_create I put all this in a structure and then passed the pointer to the structure as an argument to pthread_create (as shown). some_fxn() { //some code struct ip2 ip; ip.obj=(void*) this; ip.n_s=n_s; ip.wlist=&wlist; ip.nrsv=&nrsv; ip.pModel=pModel; ip.dim=dim; pthread_create(&callThd1[lcntr], &attr1, &Cls::Entry, (void*) &ip); } The Entry method looks something like this. void* Cls::Entry(void *ip) { struct ip2 *x; x = (struct ip2 *)ip; (reinterpret_cast<Cls1 *>(x->obj))->Run(x->dim,x->n_s, x->wlist, x->nrsv, x->pModel); } The Run method looks something like this. void Run(int dim, int n_c, vector<vector<vector<double> > > *wlist, vector<int> *nrsv, struct model* pModel ) { //some code for(int k = 0; k < n_c; ++k) { //some code end = index + nrsv[k]; //some code } I get the following error when I try to compile the program. error: no match for ‘operator+’ in ‘index + *(((std::vector<int, std::allocator<int> >*)(((unsigned int)k) * 12u)) + nrsv)’ Can someone tell me how to do it the right way.

  • php adding images to another image, exact positioning

    - by user271619
    I have a cool snippet of code that works well, except one thing. The code will take an icon I want to add to an existing picture. I can position it where I want too! Which is exactly what I need to do. However, I'm stuck on one thing, concerning the placement. The code "starting position" (on the main image: navIcons.png) is from the Bottom Right. I have 2 variables: $move_left = 10; & $move_up = 8;. So, the means I can position the icon.png 10px left, and 8px up, from the bottom right corner. I really really want to start the positioning from the Top Left of the image, so I'm really moving the icon 10px right & 8px down, from the top left position of the main image. Can someone look at my code and see if I'm just missing something that inverts that starting position? function attachIcon($imgname) { $mark = imagecreatefrompng($imgname); imagesavealpha($mark, true); list($icon_width, $icon_height) = getimagesize($imgname); $img = imagecreatefrompng('images/sprites/navIcons.png'); imagesavealpha($img, true); $move_left = 10; $move_up = 9; list($mainpic_width, $mainpic_height) = getimagesize('images/sprites/navIcons.png'); imagecopy($img, $mark, $mainpic_width-$icon_width-$move_left, $mainpic_height-$icon_height-$move_up, 0, 0, $icon_width, $icon_height); imagepng($img); // display the image + positioned icon in the browser //imagepng($img,'newnavIcon.png'); // rewrite the image with icon attached. } header('Content-Type: image/png'); attachIcon('icon.png'); ? For those who are wondering why I'd even bother doing this. In a nutshell, I like to add 16x16 icons to 1 single image, while using css to display that individual icon. This does involve me downloading the image (sprite) and open photoshop, add the new icon (positioning it), and reuploading it to the server. Not a massive ordeal, but just having fun with php.

  • VBScript Capture StdOut from ShellExecute

    - by Joe
    I am trying to run the following code snippet as part of a tool to gather and log some pertinent system diagnostics. The purpose of this snippet is to gather the result of running the command: vssadmin list writers The snippet is as follows: ' Set WshShell = CreateObject("WScript.Shell") ' WScript.Echo sCurPath & "\vsswritercheck.bat" ' Set WshShellExec = WshShell.Exec("elevate.cmd cmd.exe /c " & sCurPath & "\vsswritercheck.bat") Set oShell = CreateObject("Shell.Application") oShell.ShellExecute "cmd.exe", sCurPath & "\vsswritercheck.bat", , "runas", 1 vsswriter = VSSWriterCheck Select Case oShell.Status Case WshFinished strOutput = oShell.StdOut.ReadAll Case WshFailed strOutput = oShell.StdErr.ReadAll End Select WScript.Echo strOutPut vsswriter = strOutPut With the first code snippet (commented out) I can run the command and capture stdout from the batch file. In the second code snipped, I cannot capture stdout. I need to be able to run the batch script with Elevated permissions, so I am looking for a compromise between the functionality of the two. I cannot run the entire calling script in elevated mode due to restrictions from other pieces of functionality. I am looking for any ideas on how to add this output to my log as I am running out of options that are within the scope of basic scripts.
