    - by Daveo
    I want to have site wide default settings for all jQuery validation uses on my site, I want every form to use the below settings, but then on a per form basis change the rules and messages. Is this possible? $('#myForm').validate({ errorClass: 'field-validation-error', errorElement: 'span', errorPlacement: function(error, element) { element.next('span').remove(); error.insertAfter( element ) .removeClass('field-validation-error') .addClass('ui-state-error'); }, success: function(label) { label.remove(); } });

  • Sorting numbers in string format with Python

    - by prosseek
    I have a list that has some chapter numbers in string. When I sort the keys using keys function, it gives me wrong results. keys = ['1.1', '1.2', '2.1', '10.1'] keys.sort() print keys ['1.1', '1.2', '10.1', '2.1'] How can I use the sort function to get ['1.1', '1.2', '2.1', '10.1'] What if the array has something like this? ['1.1.1', '1.2.1', '10.1', '2.1'] - ['1.1.1','1.2.1','2.1','10.1']

  • C Programming: malloc() for a 2D array (using pointer-to-pointer)

    - by vikramtheone
    Hi Guys, yesterday I had posted a question: How should I pass a pointer to a function and allocate memory for the passed pointer from inside the called function? From the answers I got, I was able to understand what mistake I was doing. I'm facing a new problem now, can anyone help out with this? I want to dynamically allocate a 2D array, so I'm passing a Pointer-to-Pointer from my main() to another function called alloc_2D_pixels(...), where I use malloc(...) and for(...) loop to allocate memory for the 2D array. Well, after returning from the alloc_2D_pixels(...) function, the pointer-to-pointer still remains NULL, so naturally, when I try accessing or try to free(...) the Pointer-to-Pointer, the program hangs. Can anyone suggest me what mistakes I'm doing here? Help!!! Vikram SOURCE: main() { unsigned char **ptr; unsigned int rows, cols; if(alloc_2D_pixels(&ptr, rows, cols)==ERROR) // Satisfies this condition printf("Memory for the 2D array not allocated"); // NO ERROR is returned if(ptr == NULL) // ptr is NULL so no memory was allocated printf("Yes its NULL!"); // Because ptr is NULL, with any of these 3 statements below the program HANGS ptr[0][0] = 10; printf("Element: %d",ptr[0][0]); free_2D_alloc(&ptr); } signed char alloc_2D_pixels(unsigned char ***memory, unsigned int rows, unsigned int cols) { signed char status = NO_ERROR; memory = malloc(rows * sizeof(unsigned char** )); if(memory == NULL) { status = ERROR; printf("ERROR: Memory allocation failed!"); } else { int i; for(i = 0; i< cols; i++) { memory[i] = malloc(cols * sizeof(unsigned char)); if(memory[i]==NULL) { status = ERROR; printf("ERROR: Memory allocation failed!"); } } } // Inserted the statements below for debug purpose only memory[0][0] = (unsigned char)10; // I'm able to access the array from printf("\nElement %d",memory[0][0]); // here with no problems return status; } void free_2D_pixels(unsigned char ***ptr, unsigned int rows) { int i; for(i = 0; i < rows; i++) { free(ptr[i]); } free(ptr); }

  • tabexpansion doesn't fall through if overridden

    - by guillermooo
    The tabexpansion function only works partially when I override it like so: function tabexpansion { param($line, $lastWord) if ($line -eq "hey ") { "you", "Joe" } } The custom completions work as expected, but now I only get the default autocomplete behavior for cmdlet names, not parameters. So New-TAB works fine, but New-Alias -TAB doesn't. How do I get the regular completions too after overriding tabexpansion?

  • mail sent with php's mail() has blank From field

    - by Nikkeloodeni
    Hi, I'm sending email with PHP's mail function. It works just as it should except all email clients show blank From-field. Here's how i'm using the function: mail( '[email protected]', "Example subject", $msg, implode( "\r\n", array( Content-Type: text/html; charset=UTF-8', 'From: [email protected]') ) ); As i said everything works fine except From field is all blank when the message arrives. Any ideas why this is happening?

  • jQuery live keydown doesn't register until second keydown

    - by Simon
    Hi there, I'm trying to add a class (.active) to a text field once the user starts typing. I got it to work somewhat with the following code, but for some reason the .active class is not applied immediately when the user starts typing, it's only applied after a second letter has been typed. Any ideas? $(document).ready(function() { loginField = $('.field'); loginField.live('keydown', function(){ if ($(this).val()){ $(this).addClass('active'); } }); });

  • Binding functions of derived class with luabind

    - by Anamon
    I am currently developing a plugin-based system in C++ which provides a Lua scripting interface, for which I chose to use luabind. I'm using Lua 5 and luabind 0.9, both statically linked and compiled with MSVC++ 8. I am now having trouble binding functions with luabind when they are defined in a derived class, but not its parent class. More specifically, I have an abstract base class called 'IPlugin' from which all plugin classes inherit. When the plugin manager initialises, it registers that class and its functions like this: luabind::open(L); luabind::module(L) [ luabind::class_("IPlugin") .def("start", (void(IPlugin::*)())&IPlugin::start) ]; As it is only known at runtime what effective plugin classes are available, I had to solve loading plugins in a kind of roundabout way. The plugin manager exposes a factory function to Lua, which takes the name of a plugin class and a desired object name. The factory then creates the object, registers the plugin's class as inheriting from the 'IPlugin' base class, and immediately calls a function on the created object that registers itself as a global with the Lua state, like this: void PluginExample::registerLuaObject(lua_State *L, string a_name) { luabind::globals(L)[a_name] = (PluginExample*)this; } I initially did this because I had problems with Lua determining the most derived class of the object, as if I register it from the StreamManager it is only known as a subtype of 'IPlugin' and not the specific subtype. I'm not sure anymore if this is even necessary though, but it works and the created object is subsequently accessible from Lua under 'a_name'. The problem I have, though, is that functions defined in the derived class, which were not declared at all in the parent class, cannot be used. Virtual functions defined in the base class, such as 'start' above, work fine, and calling them from Lua on the new object runs the respective redefined code from the 'PluginExample' class. But if I add a new function to 'PluginExample', here for example a function taking no arguments and returning void, and register it like this: luabind::module(L) [ luabind::class_("PluginExample") .def(luabind::constructor()) .def("func", &PluginExample::func) ]; calling 'func' on the new object yields the following Lua runtime error: No matching overload found, candidates: void func(PluginExample&) I am correctly using the ':' syntax so the 'self' argument is not needed and it seems suddenly Lua cannot determine the derived type of the object anymore. I am sure I am doing something wrong, probably having to do with the two-step binding required by my system architecture, but I can't figure out where. I'd much appreciate some help =)

  • jq div display script webkit issues

    - by Tom
    $(document).ready(function() { $('#chekboxes a').click(function(e) { $('.visible').removeClass('visible').addClass('invisible'); var thediv = $(this).attr('href'); $(thediv).removeClass('invisible').addClass('visible'); }) }); This simple bit of jq works in FF and not in Chrome and Safari. Despite googling widely, I cannot tell whether there's a way to make it work in Safari and Chrome or not. Does anyone know a fix or what is wrong ? Thanks, Tom

  • Write Scheme data structures so they can be eval-d back in, or alternative

    - by Jesse Millikan
    I'm writing an application (A juggling pattern animator) in PLT Scheme that accepts Scheme expressions as values for some fields. I'm attempting to write a small text editor that will let me "explode" expressions into expressions that can still be eval'd but contain the data as literals for manual tweaking. For example, (4hss->sexp "747") is a function call that generates a legitimate pattern. If I eval and print that, it becomes (((7 3) - - -) (- - (4 2) -) (- (7 2) - -) (- - - (7 1)) ((4 0) - - -) (- - (7 0) -) (- (7 2) - -) (- - - (4 3)) ((7 3) - - -) (- - (7 0) -) (- (4 1) - -) (- - - (7 1))) which can be "read" as a string, but will not "eval" the same as the function. For this statement, of course, what I need would be as simple as (quote (((7 3... but other examples are non-trivial. This one, for example, contains structs which print as vectors: pair-of-jugglers ; --> (#(struct:hand #(struct:position -0.35 2.0 1.0) #(struct:position -0.6 2.05 1.1) 1.832595714594046) #(struct:hand #(struct:position 0.35 2.0 1.0) #(struct:position 0.6 2.0500000000000003 1.1) 1.308996938995747) #(struct:hand #(struct:position 0.35 -2.0 1.0) #(struct:position 0.6 -2.05 1.1) -1.3089969389957472) #(struct:hand #(struct:position -0.35 -2.0 1.0) #(struct:position -0.6 -2.05 1.1) -1.8325957145940461)) I've thought of at least three possible solutions, none of which I like very much. Solution A is to write a recursive eval-able output function myself for a reasonably large subset of the values that I might be using. There (probably...) won't be any circular references by the nature of the data structures used, so that wouldn't be such a long job. The output would end up looking like `(((3 0) (... ; ex 1 `(,(make-hand (make-position ... ; ex 2 Or even worse if I could't figure out how to do it properly with quasiquoting. Solution B would be to write out everything as (read (open-input-string "(big-long-s-expression)")) which, technically, solves the problem I'm bringing up but is... ugly. Solution C might be a different approach of giving up eval and using only read for parsing input, or an uglier approach where the s-expression is used as directly data if eval fails, but those both seem unpleasant compared to using scheme values directly. Undiscovered Solution D would be a PLT Scheme option, function or library I haven't located that would match Solution A. Help me out before I start having bad recursion dreams again.

  • Translate COM error codes in C#

    - by Paul Keister
    In C, Pascal, and C++ it is possible to use the FormatMessage function to retrieve a "friendly" error message that corresponds to a COM HRESULT error code. This question contains sample code that demonstrates the C++ approach. Of course it would be possible to build a managed C++ assembly to perform this function for C# and VB.NET code, but I'm wondering: is there a way to translate COM error codes using the .NET system libraries?

  • How to read date from the form and calculate a timestamp

    - by Vafello
    I would like to calculate a timestamp based on the input date. I would like to calculate it from the user input (something like 12/12/2011) I guess I need a function that changes the format to something readable for php and then calculate timestamp for this date. Maybe I should use strtotime() function? Any ideas will be appreciated. $date = $_POST['date']; <input type="text" name="date" value="">

  • jqtransform and collapsed DIV

    - by Marco
    Hello, I am using a jQuery plugin called: jqtransform This plugin uses JavaScript to apply CSS styles to form elements. The problem that I have consists in the following scenario: I’m building a search page, with a advanced search option. When the page loads, the div called “advancedSearch” is hidden, and it will only show if the user clicks a element. Inside the div#advancedSearch I have several form elements. However, if I hide the div#advancedSearch with the CSS style: “diplay:none;”, the jqtransform plugin doesn’t work correctly with the elements that are hidden. So my solution was to hide the div#advancedsearch with JavaScript. This actually works, and it does not matter if it’s done after the document is ready or not. But… with the JavaScript solution, the div#advancedSearch stays visible for a couple of milliseconds… which is visually annoying. So I was wondering if the solution to this problem would be in the CSS, or in correcting the jqtransform plugin, or even in finding a way to immediately hide the div#advancedSearch with JS making it immediately hidden. UPDATE 1 After jeerose comment I decided to place here my function (please note that the <%= % are ASP.Net tags, that I use to get the images path) $('.toggleAdvancedSearch').click(function() { $('#advancedSearchWrap').slideToggle(250); $('form.jqtransform').jqTransform({ imgPath: '<%= ResolveClientUrl("~/masterpages/img/jqtransform/") %>' }); return false; }); UPDATE 2 To test the problem, I did the following: Added another element to the page, with the ID “applyStyle”, and onClick I call the $('form').jqTransform(); Disabled the the $('form').jqTransform(); from the load of the page. If I press the a#applyStyle, before expanding the div#advancedSearch I get the same problem that I had. But if I expand the the div#advancedSearch and press the the a#applyStyle after, the problem is solved. However, if I run the page with the $('form').jqTransform(); function on the load, I cannot reapply it after with the pressing of the a#applyStyle. I think that the solution could be: disabling the all the elements that are inside the div#advancedSearch, and on the same function that expands the div, make It also apply the styles to the elements that are inside the div#advancedSearch. However, I don’t know how to do this (nether if this will work). PS: This seems to be a known issue with the plugin, but I cannot wait indefinitely for a solution.

  • C# problem with two threads and hardware access

    - by mack369
    I'm creating an application which communicates with the device via FT2232H USB/RS232 converter. For communication I'm using FTD2XX_NET.dll library from FTDI website. I'm using two threads: first thread continuously reads data from the device the second thread is the main thread of the Windows Form Application I've got a problem when I'm trying to write any data to the device while the receiver's thread is running. The main thread simply hangs up on ftdiDevice.Write function. I tried to synchronize both threads so that only one thread can use Read/Write function at the same time, but it didn't help. Below code responsible for the communication. Note that following functions are methods of FtdiPort class. Receiver's thread private void receiverLoop() { if (this.DataReceivedHandler == null) { throw new BackendException("dataReceived delegate is not set"); } FTDI.FT_STATUS ftStatus = FTDI.FT_STATUS.FT_OK; byte[] readBytes = new byte[this.ReadBufferSize]; while (true) { lock (FtdiPort.threadLocker) { UInt32 numBytesRead = 0; ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead); if (ftStatus == FTDI.FT_STATUS.FT_OK) { this.DataReceivedHandler(readBytes, numBytesRead); } else { Trace.WriteLine(String.Format("Couldn't read data from ftdi: status {0}", ftStatus)); Thread.Sleep(10); } } Thread.Sleep(this.RXThreadDelay); } } Write function called from main thread public void Write(byte[] data, int length) { if (this.IsOpened) { uint i = 0; lock (FtdiPort.threadLocker) { this.ftdiDevice.Write(data, length, ref i); } Thread.Sleep(1); if (i != (int)length) { throw new BackendException("Couldnt send all data"); } } else { throw new BackendException("Port is closed"); } } Object used to synchronize two threads static Object threadLocker = new Object(); Method that starts the receiver's thread private void startReceiver() { if (this.DataReceivedHandler == null) { return; } if (this.IsOpened == false) { throw new BackendException("Trying to start listening for raw data while disconnected"); } this.receiverThread = new Thread(this.receiverLoop); //this.receiverThread.Name = "protocolListener"; this.receiverThread.IsBackground = true; this.receiverThread.Start(); } The ftdiDevice.Write function doesn't hang up if I comment following line: ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead);

  • In CodeIgniter, how to clear "form data" after redirecting page

    I'm not sure I explained it correctly in the question title, so here's the details: Login controller: function authenticate() { if ( authorized ) { redirect('lobby'); } else { redirect('login'); } } Lobby controller: function index() { //load lobby view } What happens is that in the login page, I enter user / pass, click Login, then authenticate() is called, and redirects me to the Lobby. However, when I click refresh while on the Lobby, the login form gets submitted again, so I get "logged in" again. How do I prevent that from happening?
