  • Administrator's shortcut to batch file with double quoted parameters

    - by XXB
    Take an excruciatingly simple batch file: echo hi pause Save that as test.bat. Now, make a shortcut to test.bat. The shortcut runs the batch file, which prints "hi" and then waits for a keypress as expected. Now, add some argument to the target of the shortcut. Now you have a shortcut to: %path%\test.bat some args The shortcut runs the batch file as before. Now, run the shortcut as administrator. (This is on Windows 7 by the way.) You can use either right-click - Run as Administrator, or go to the shortcut's properties and check the box in the advanced section. Tell UAC that it's okay and once again the shortcut runs the batch file as expected. Now, change the arguments in the target of the shortcut to add double quotes: %path%\test.bat "some args" Now try the shortcut as administrator. It doesn't work this time! A command window pops up and and disappears too fast to see any error. I tried adding test.log 2&1 to the shortcut, but no log is created in this case. Try running the same shortcut (with the double quotes) but not as Administrator. It runs the batch file fine. So, it seems the behavior is not because of the double quoted parameters, and it's not because it's run as Administrator. It's some weird combination of the two. I also tried running the same command from an administrator's command window. This ran the batch file as expected without error. Running the shortcut from the command window spawned a new command window which flashed and went away. So apparently the issue is caused by a combination of administrator, the shortcut, and the double quotes. I'm totally stumped, does anyone have any idea what's going on?

  • codeigniter and OOP general question regarding calling functions, and the parent constuctor

    - by thrice801
    Ok so I have some gaps in my understanding of PHP OOP, classes and functions specifically, this whole constructor class deal. I use both Zend and CI but right now Im trying to figure this out in CI as it is less complicated. So all Im trying to do is understand how to call a function from a view page in code igniter. I understand that might go against MVC but Im working with an api and search results not from my database, so basically, I want to define a function in my class that I am able to call in one of my view pages.. and I keep getting "Fatal error: Call to undefined function functionname" error no matter what I try. I thought I just had to declare public function testing() { echo "testing testing 123; } but calling that from the view I get that error. Then I read something about having to go parent::Controller(); in the index of the class where the testing function also resides? But that didnt work either. Anyways, ya, can someone explain what I need to do in order to call the "testing()" function on one of my view pages? and clarification on the constructor class and what exactly parent::Controller() even does, would be much appreciated as well.

  • Loading Liferay Properties from Spring IoC container (to get jdbc connection parameters)

    - by mox601
    I'm developing some portlets for Liferay Portal 5.2.3 with bundled tomcat 6.0.18 using Spring IoC container. I need to map the User_ table used in Liferay database to an entity with Hibernate, so I need to use two different dataSources to separate the liferay db from the db used by portlets. My jdbc.properties has to hold all connection parameters for both databases: no problem for the one used by portlets, but I am having issues determining which database uses liferay to hold its data. My conclusion is that i should have something like this: liferayConnection.url=jdbc:hsqldb:${liferay.home}/data/hsql/lportal in order to get the database url dynamically loaded, according to Liferay properties found in portal-ext.properties. (Or, better, load the whole portal-ext.properties and read database properties from there). The problem is that the placeholder is not resolved: Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'liferayDataSource' defined in class path resource [WEB-INF/applicationContext.xml]: Could not resolve placeholder 'liferay.home' To dodge this problem I tried to load explicitly portal-ext.properties with a Spring bean: <bean id="liferayPropertiesConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" p:location="../../portal-ext.properties"/> but no luck: liferay.home is not resolved but there aren't other errors. How can I resolve the placeholder defined by Liferay? Thanks

  • Setting corelocation results to NSNumber object parameters

    - by Dan Ray
    This is a weird one, y'all. - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { CLLocationCoordinate2D coordinate = newLocation.coordinate; self.mark.longitude = [NSNumber numberWithDouble:coordinate.longitude]; self.mark.latitude = [NSNumber numberWithDouble:coordinate.latitude]; NSLog(@"Got %f %f, set %f %f", coordinate.latitude, coordinate.longitude, self.mark.latitude, self.mark.longitude); [manager stopUpdatingLocation]; manager.delegate = nil; if (self.waitingForLocation) { [self completeUpload]; } } The latitude and longitude in that "mark" object are synthesized parameters referring to NSNumber iVars. In the simulator, my NSLog output for that line in the middle there reads: 2010-05-28 15:08:46.938 EverWondr[8375:207] Got 37.331689 -122.030731, set 0.000000 -44213283338325225829852024986561881455984640.000000 That's a WHOLE lot further East than 1 Infinite Loop! The numbers are different on the device, but similar--lat is still zero and long is a very unlikely high negative number. Elsewhere in the controller I'm accepting a button press and uploading a file (an image I just took with the camera) with its geocoding info associated, and I need that self.waitingForLocation to inform the CLLocationManager delegate that I already hit that button and once its done its deal, it should go ahead and fire off the upload. Thing is, up in the button-click-receiving method, I test see if CL is finished by testing self.mark.latitude, which seems to be getting set zero...

  • jQuery Flow Control (if then from URL params)

    - by Ryan Max
    Strangely enough I am more familiar with jQuery than I am with javascript. I need to be able to add a class to the body tag of a document depending on what specific forum page i'm on in a phpbb forum. Due to the nature of phpbb I can't actually do this flow control in php, so I am using jquery. Here's my code (the first part is an extend that gets the url parameters like so http://www.mysite.com/viewforum.php?f=3 var forum = $.getUrlVar('f'); will make forum == 3 because of the nature of phpbb i can't really do any flow control with php. So I am using jquery. This is my code: $(document).ready(function(){ $.extend({ getUrlVars: function(){ var vars = [], hash; var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&'); for(var i = 0; i < hashes.length; i++) { hash = hashes[i].split('='); vars.push(hash[0]); vars[hash[0]] = hash[1]; } return vars; }, getUrlVar: function(name){ return $.getUrlVars()[name]; } }); }); $(document).ready(function(){ var forum = $.getUrlVar('f'); if (forum == 3){ $('body').toggleClass('black'); } }); Yet this isn't working. Any idea why not?

  • Adding Functions to an Implementation of Vector

    I have this implementation of vector that I've been working on for a few days using examples from a textbook: #include <iostream> #include <string> #include <cassert> #include <algorithm> #include <cstring> // Vector.h using namespace std; template <class T> class Vector { public: typedef T * iterator; Vector(); Vector(unsigned int size); Vector(unsigned int size, const T & initial); Vector(const Vector<T> & v); // copy constructor ~Vector(); unsigned int capacity() const; // return capacity of vector (in elements) unsigned int size() const; // return the number of elements in the vector bool empty() const; iterator begin(); // return an iterator pointing to the first element iterator end(); // return an iterator pointing to one past the last element T & front(); // return a reference to the first element T & back(); // return a reference to the last element void push_back(const T & value); // add a new element void pop_back(); // remove the last element void reserve(unsigned int capacity); // adjust capacity void resize(unsigned int size); // adjust size void erase(unsigned int size); // deletes an element from the vector T & operator[](unsigned int index); // return reference to numbered element Vector<T> & operator=(const Vector<T> &); private: unsigned int my_size; unsigned int my_capacity; T * buffer; }; template<class T>// Vector<T>::Vector() { my_capacity = 0; my_size = 0; buffer = 0; } template<class T> Vector<T>::Vector(const Vector<T> & v) { my_size = v.my_size; my_capacity = v.my_capacity; buffer = new T[my_size]; for (int i = 0; i < my_size; i++) buffer[i] = v.buffer[i]; } template<class T>// Vector<T>::Vector(unsigned int size) { my_capacity = size; my_size = size; buffer = new T[size]; } template<class T>// Vector<T>::Vector(unsigned int size, const T & initial) { my_size = size; //added = size my_capacity = size; buffer = new T [size]; for (int i = 0; i < size; i++) buffer[i] = initial; } template<class T>// Vector<T> & Vector<T>::operator = (const Vector<T> & v) { delete[ ] buffer; my_size = v.my_size; my_capacity = v.my_capacity; buffer = new T [my_size]; for (int i = 0; i < my_size; i++) buffer[i] = v.buffer[i]; return *this; } template<class T>// typename Vector<T>::iterator Vector<T>::begin() { return buffer; } template<class T>// typename Vector<T>::iterator Vector<T>::end() { return buffer + size(); } template<class T>// T& Vector<T>::Vector<T>::front() { return buffer[0]; } template<class T>// T& Vector<T>::Vector<T>::back() { return buffer[size - 1]; } template<class T> void Vector<T>::push_back(const T & v) { if (my_size >= my_capacity) reserve(my_capacity +5); buffer [my_size++] = v; } template<class T>// void Vector<T>::pop_back() { my_size--; } template<class T>// void Vector<T>::reserve(unsigned int capacity) { if(buffer == 0) { my_size = 0; my_capacity = 0; } if (capacity <= my_capacity) return; T * new_buffer = new T [capacity]; assert(new_buffer); copy (buffer, buffer + my_size, new_buffer); my_capacity = capacity; delete[] buffer; buffer = new_buffer; } template<class T>// unsigned int Vector<T>::size()const { return my_size; } template<class T>// void Vector<T>::resize(unsigned int size) { reserve(size); my_size = size; } template<class T>// T& Vector<T>::operator[](unsigned int index) { return buffer[index]; } template<class T>// unsigned int Vector<T>::capacity()const { return my_capacity; } template<class T>// Vector<T>::~Vector() { delete[]buffer; } template<class T> void Vector<T>::erase(unsigned int size) { } int main() { Vector<int> v; v.reserve(2); assert(v.capacity() == 2); Vector<string> v1(2); assert(v1.capacity() == 2); assert(v1.size() == 2); assert(v1[0] == ""); assert(v1[1] == ""); v1[0] = "hi"; assert(v1[0] == "hi"); Vector<int> v2(2, 7); assert(v2[1] == 7); Vector<int> v10(v2); assert(v10[1] == 7); Vector<string> v3(2, "hello"); assert(v3.size() == 2); assert(v3.capacity() == 2); assert(v3[0] == "hello"); assert(v3[1] == "hello"); v3.resize(1); assert(v3.size() == 1); assert(v3[0] == "hello"); Vector<string> v4 = v3; assert(v4.size() == 1); assert(v4[0] == v3[0]); v3[0] = "test"; assert(v4[0] != v3[0]); assert(v4[0] == "hello"); v3.pop_back(); assert(v3.size() == 0); Vector<int> v5(7, 9); Vector<int>::iterator it = v5.begin(); while (it != v5.end()) { assert(*it == 9); ++it; } Vector<int> v6; v6.push_back(100); assert(v6.size() == 1); assert(v6[0] == 100); v6.push_back(101); assert(v6.size() == 2); assert(v6[0] == 100); v6.push_back(101); cout << "SUCCESS\n"; } So far it works pretty well, but I want to add a couple of functions to it that I can't find examples for, a SWAP function that would look at two elements of the vector and switch their values and and an ERASE function that would delete a specific value or range of values in the vector. How should I begin implementing the two extra functions?

  • ASP.Net MVC Json Result: Parameters passed to controller method issue

    - by Moskie
    I'm having a problem getting a controller method that returns a JsonResult to accept parameters passed via the JQuery getJSON method. The code I’m working on works fine when the second parameter ("data") of the getJSON method call is null. But when I attempt to pass in a value there, it seems as if the controller method never even gets called. In this example case, I just want to use an integer. The getJSON call that works fine looks like this: $.getJSON(”/News/ListNewsJson/”, null, ListNews_OnReturn); The controller method is like this: public JsonResult ListNewsJson(int? id) { … return Json(toReturn); } By putting a breakpoint in the ListNewsJson method, I see that this method gets called when the data parameter of getJSON is null, but when I replace it with value, such as, say, 3: $.getJSON(”/News/ListNewsJson/”, 3, ListNews_OnReturn); … the controller method/breakpoint is never hit. Any idea what I'm doing wrong? I should also mention that the controller method works fine if I manually go to the address via my browser ("/News/ListNewsJson/3").

  • Two classes and inline functions

    - by klew
    I have two classes and both of them uses some of the other class, on example: // class1.h class Class1; #include "class2.h" class Class1 { public: static Class2 *C2; ... }; // class2.h class Class2; #include "class1.h" class Class2 { public: static Class1 *C1; ... }; And when I define it like in example above, it works (I also have some #ifndef to avoid infinite header recurency). But I also want to add some inline functions to my classes. And I read here that I should put definition of inline function in header file, because it won't work if I'll put them in cpp file and want to call them from other cpp file (when I do it I get undefined reference during linking). But the problem here is with something like this: // class1.h ... inline void Class1::Foo() { C2->Bar(); } I get error: invalid use of incomplete type ‘struct Class2’. So how can I do it?

  • Reading component parameters and setting defaults

    - by donut
    I'm pulling my hair on this because it should be simple, but can't get it to do the right thing. What's the best practice way of doing the following I've created a custom component that extends <s:Label> so now the Label has additional properties color2 color3 value which can be called like this and are used in the skin. <s:CustomLabel text="Some text" color2="0x939202" color3="0x999999" value="4.5" /> If I don't supply these parameters, I'd like some defaults to be set. So far I've had some success, but it doesn't work 100% of the time, which leads me to think that I'm not following best practices when setting those defaults. I do it now like this: [Bindable] private var myColor2:uint = 0x000000; [Bindable] private var myColor3:uint = 0x000000; [Bindable] private var myValue:Number = 10.0; then in the init function, I do a variation of this to set the default myValue = hostComponent.value; myValue = (hostComponent.value) ? hostComponent.value : 4.5; Sometimes it works, sometimes it doesn't, depending on the type of variable I'm trying to set. I eventually decided to read them as Strings then convert them to the desired type, but it seems that this also works half the time.

  • Optional route parameters in ASP.NET 4 RTM no longer work as before

    - by Simon_Weaver
    I upgraded my project to ASP.NET 4 RTM with ASP.NET MVC 2.0 RTM today. I was previously using ASP.NET 3.5 with ASP.NET MVC 2.0 RTM. Some of my routes don't work suddenly and I don't know why. I'm not sure if something changed between 3.5 and 4.0 - or if this was a regression type issue in the 4.0 RTM. (I never previously tested my app with 4.0). I like to use Url.RouteUrl("route-name", routeParams) to avoid ambiguity when generating URLs. Here's my route definition for a gallery page. I want imageID to be optional (you get a thumbnail page if you don't specify it). // gallery id routes.MapRoute( "gallery-route", "gallery/{galleryID}/{imageID}/{title}", new { controller = "Gallery", action = "Index", galleryID = (string) null, imageID = (string) null, title = (string) null} ); In .NET 3.5 / ASP.NET 2.0 RTM / IIS7 Url.RouteUrl("gallery-route", "cats") => /gallery/cats Url.RouteUrl("gallery-route", "cats", 4) => /gallery/cats/4 Url.RouteUrl("gallery-route", "cats", 4, "tiddles") => /gallery/cats/4/tiddles In .NET 4.0 RTM / ASP.NET 2.0 RTM / IIS7 Url.RouteUrl("gallery-route", "cats") => null Url.RouteUrl("gallery-route", "cats", 4) => /gallery/cats/4 Url.RouteUrl("gallery-route", "cats", 4, "tiddles") => /gallery/cats/4/tiddles Previously I could supply only the galleryID and everything else would be ignored in the generated URL. But now it's looking like I need to specify all the parameters up until title - or it gives up in determining the URL. Incoming URLs work fine for /gallery/cats and that is correctly mapped through this rule with imageID and title both being assigned null in my controller. I also tested the INCOMING routes with http://haacked.com/archive/2008/03/13/url-routing-debugger.aspx and they all work fine.

  • getting the list of all functions executed like call stack in asp.net

    - by sridhar
    Hi, I am having trouble with debugging one of the problems that I am having in our website. This is the problem. I have a webpage that contains the photo of an employee and information related to the employee. When the user logins to our website, we are storing the details of the employee in session. I am setting the image url for the photo of an employee as follows. imgEEPhoto.ImageUrl = imgPhoto.aspx?Company=XXXX&Empno=YYYY. Inside the page imgPhoto.aspx, I am checking if the session is alive for that user. when I login to the page that has the employee photo sometimes the photo is not displayed. It is because I am checking whether the session is alive inside the imgPhoto.aspx page. sometimes the session is alive and sometimes the session is not alive. It looks like there is some function that is setting the session to null asynchronously. I am not knowing how to track that function. so I am thinking that inside the imgPhoto.aspx page, if I can get the list of all functions that have been executed so far, I could track the function that is resetting the session. Is there a way to find this? If there is no another way to debug this problem, please let me know. Thanks, sridhar.

  • advanced Visual Studio kung-fu test -- Calling functions from the Immediate Window during debugging

    - by kizzx2
    I see some related questions have been asked, but they're either too advanced for me to grasp or lacking a step-by-step guide from start to finish (most of them end up being insider talk of their own experiment results). OK here it is, given this simple program: #include <stdio.h> #include <string.h> int main() { FILE * f; char buffer[100]; memset(buffer, 0, 100); fun(); f = fopen("main.cpp", "r"); fread(buffer, 1, 99, f); printf(buffer); fclose(f); return 0; } What it does is basically print itself (assume file name is main.cpp). Question How can I have it print another file, say foobar.txt without modifying the source code? It has something to do with running it through VS's, stepping through the functions and hijacking the FILE pointer right before fread() is called. No need to worry about leaking resources by calling fclose(). I tried the simple f = fopen("foobar.txt", "r") which gave CXX0017: Error: symbol "fopen" not found Any ideas? Edit I found out the solution accidentally on Debugging Mozilla on Windows FAQ. The correct command to put into the Immediate Window is f = {,,MSVCR100D}fopen("foo.txt", "r") However, it doesn't really answer this question: I still don't understand what is going on here. How to systematically find out the {,,MSVCR100D} part for any given method? I know the MSVCR version changes from system to system. How can I find that out? Could anyone explain the curly brace syntax, especially, what are those two commas doing there? Are there more hidden gems using this syntax?

  • Which languages support *recursive* function literals / anonymous functions?

    - by Hugh Allen
    It seems quite a few mainstream languages support function literals these days. They are also called anonymous functions, but I don't care if they have a name. The important thing is that a function literal is an expression which yields a function which hasn't already been defined elsewhere, so for example in C, &printf doesn't count. EDIT to add: if you have a genuine function literal expression <exp>, you should be able to pass it to a function f(<exp>) or immediately apply it to an argument, ie. <exp>(5). I'm curious which languages let you write function literals which are recursive. Wikipedia's "anonymous recursion" article doesn't give any programming examples. Let's use the recursive factorial function as the example. Here are the ones I know: JavaScript / ECMAScript can do it with callee: function(n){if (n<2) {return 1;} else {return n * arguments.callee(n-1);}} it's easy in languages with letrec, eg Haskell (which calls it let): let fac x = if x<2 then 1 else fac (x-1) * x in fac and there are equivalents in Lisp and Scheme. Note that the binding of fac is local to the expression, so the whole expression is in fact an anonymous function. Are there any others?

  • [Doxygen] How to documenting global dependencies for functions?

    - by Thomas Matthews
    I've got some C code from a 3rd party vendor (for an embedded platform) that uses global variables (for speed & space optimizations). I'm documenting the code, converting to Doxygen format. How do I put a note in the function documentation that the function requires on global variables and functions? Doxygen has special commands for annotating parameters and return values as describe here: Doxygen Special Commands. I did not see any commands for global variables. Example C code: extern unsigned char data_buffer[]; //!< Global variable. /*! Returns the next available data byte. * \return Next data byte. */ unsigned char Get_Byte(void) { static unsigned int index = 0; return data_buffer[index++]; //!< Uses global variable. } In the above code, I would like to add Doxygen comments that the function depends on the global variable data_buffer.

  • Dependency Injection for objects that require parameters

    - by Andrew
    All of our reports are created from object graphs that are translated from our domain objects. To enable this, we have a Translator class for each report, and have been using Dependency Injection for passing in dependencies. This worked great, and would yield nice classes structured like this: public class CheckTranslator : ICheckTranslator { public CheckTranslator (IEmployeeService empSvc , IPaycheckService paySvc) { _empSvc = empSvc; _paySvc = paySvc; } public Check CreateCheck() { //do the translation... } } However, in some cases the mapping has many different grouping options. As a result, the c-tor would turn into a mix of class dependencies and parameters. public class CheckTranslator : ICheckTranslator { public CheckTranslator (IEmployeeService empSvc , IPaycheckService paySvc , bool doTranslateStubData , bool doAttachLogo) { _empSvc = empSvc; _paySvc = paySvc; _doTranslateStubData = doTranslateStubData; _doAttachLogo = doAttachLogo; } public Check CreateCheck() { //do the translation... } } Now, we can still test it, but it no longer really works with an IoC container, at least in a clean fashion. Plus, we can no longer call the CreateCheck twice if the settings are different for each check. While I recognize it's a problem, I don't necessarily see the right solution. It seems kind of strange to create a Factory for each class ... or is this the best way?

  • How to feature-detect/test for specific jQuery (and Javascript) methods/functions used

    - by Zildjoms
    good day everyone, hope yer all doin awesome am very new to javascript and jquery, and i (think) i have come up with a simple fade-in/out implementation on a site am workin on (check out http://www.s5ent.com/expandjs.html - if you have the time to check it for inefficiency or what that'd be real sweet). i use the following functions/methods/collections and i would like to do a feature test before using them. uhm.. how? or is there a better way to go about this? jQuery $ .fadeIn([duration]) .fadeOut([duration]) .attr(attributeName,value) .append(content) .each(function(index,Element)) .css(propertyName,value) .hover(handlerIn(eventObject),handlerOut(eventObject)) .stop([clearQueue],[jumpToEnd]) .parent() .eq(index) JavaScript setInterval(expression,timeout) clearInterval(timeoutId) setTimeout(expression,timeout) clearTimeout(timeoutId) i tried looking into jquery.support for the jquery ones, but i find myself running into conceptual problems with it, i.e. for fadein/fadeout, i (think i) should test for $.support.opacity, but that would be false in ie whereas ie6+ could still fairly render the fades. also am using jquery 1.2.6 coz that's enough for what i need. the support object is in 1.3. so i'm hoping to avoid dragging-in more unnecessary code if i can. i also worked with browser sniffing, no matter how frowned-upon. but that's also a bigger problem for me because of non-standard ua strings and spoofing and everything else am not aware of. so how do you guys think i should go about this? or should i even? is there a better way to go about making sure that i don't run code that'll eventually break the page? i've set it up to degrade into a css hover when javascript ain't there.. expertise needed. much appreciated, thanks guyz!

  • How to pass parameters to manage_shared_memory.construct() in Boost.Interprocess

    - by recipriversexclusion
    I've stared at the Boost.Interprocess documentation for hours but still haven't been able to figure this out. In the doc, they have an example of creating a vector in shared memory like so: //Define an STL compatible allocator of ints that allocates from the managed_shared_memory. //This allocator will allow placing containers in the segment typedef allocator<int, managed_shared_memory::segment_manager> ShmemAllocator; //Alias a vector that uses the previous STL-like allocator so that allocates //its values from the segment typedef vector<int, ShmemAllocator> MyVector; int main(int argc, char *argv[]) { //Create a new segment with given name and size managed_shared_memory segment(create_only, "MySharedMemory", 65536); //Initialize shared memory STL-compatible allocator const ShmemAllocator alloc_inst (segment.get_segment_manager()); //Construct a vector named "MyVector" in shared memory with argument alloc_inst MyVector *myvector = segment.construct<MyVector>("MyVector")(alloc_inst); Now, I understand this. What I'm stuck is how to pass a second parameter to segment.construct() to specify the number of elements. The interprocess document gives the prototype for construct() as MyType *ptr = managed_memory_segment.construct<MyType>("Name") (par1, par2...); but when I try MyVector *myvector = segment.construct<MyVector>("MyVector")(100, alloc_inst); I get compilation errors. My questions are: Who actually gets passed the parameters par1, par2 from segment.construct, the constructor of the object, e.g. vector? My understanding is that the template allocator parameter is being passed. Is that correct? How can I add another parameter, in addition to alloc_inst that is required by the constructor of the object being created in shared memory? There's very little information other than the terse Boost docs on this.

  • Implementing custom Matlab functions in Simulink

    - by niko
    Hi, I would like to use custom Matlab function in Simulink. So far I have done it by placing Embedded Matlab Fuction block. However if the custom function contains another custom function the compile process fails. Here is the example of function I am trying to embed in the simulation: function [c, d, iterationsCount] = decodeLDPC(y, H, variance) Lci = initializeLq(y, H, variance); Lr = getLr(Lci); [Lq, c] = getLq(Lci, H, Lr); iterationsCount = 1; while(sum(mod(c * H', 2)) ~= 0) Lr = getLr(Lq); [Lq, c] = getLq(Lq, H, Lr); iterationsCount = iterationsCount + 1; end; G = getGeneratorMatrix(H); d = c/G; where initializeLq and getLr are custom functions as well. I would be very thankful if anyone could suggest a method to implement the above function in the simulation. Thank you.

  • HTTP POST prarameters order / REST urls

    - by pq
    Let's say that I'm uploading a large file via a POST HTTP request. Let's also say that I have another parameter (other than the file) that names the resource which the file is updating. The resource cannot be not part of the URL the way you can do it with REST (e.g. foo.com/bar/123). Let's say this is due to a combination of technical and political reasons. The server needs to ignore the file if the resource name is invalid or, say, the IP address and/or the logged in user are not authorized to update the resource. Looks like, if this POST came from an HTML form that contains the resource name first and file field second, for most (all?) browsers, this order is preserved in the POST request. But it would be naive to fully rely on that, no? In other words the order of HTTP parameters is insignificant and a client is free to construct the POST in any order. Isn't that true? Which means that, at least in theory, the server may end up storing the whole large file before it can deny the request. It seems to me that this is a clear case where RESTful urls have an advantage, since you don't have to look at the POST content to perform certain authorization/error checking on the request. Do you agree? What are your thoughts, experiences?

  • FormMethod.Get and query string parameters

    - by parminder
    Hi Experts, I am working on a website in asp.net mvc. I have to show a view where user put some search values like tags and titles to search. I want to use the same Index method for that. I have make my form to use formMethod.Get to send the parameters as querystring. so here is the method [HttpGet] public ActionResult Index(string title, string tags, int? page) { if (string.IsNullOrEmpty(title) return View(null); var list = GetSomeData(); return View(list); } here is my view <div id="searchBox"> <% using (Html.BeginForm(null, null, FormMethod.Get)) { %> <table> <tr> <td> <input type="hidden" id="isPosted" name="isPosted" value="1" /> I am looking for <%=Html.TextBox("Title")%> Tags: <%=Html.TextBox("Tags")%> <input id="search" type="submit" value="Search" /> </td> </tr> </table> <% } %> So when the user first visit the page, he will see only two text boxs and a button. but when he types something in the title and tags and click the search button i will load the view with some data. Now the problem is when i type something in title and tags box and click search, they are received in the method, but are not visible in the url. Is there anything i m doing wrong. help will be appreciated. Regards Parminder

  • Monads and custom traversal functions in Haskell

    - by Bill
    Given the following simple BST definition: data Tree x = Empty | Leaf x | Node x (Tree x) (Tree x) deriving (Show, Eq) inOrder :: Tree x -> [x] inOrder Empty = [] inOrder (Leaf x) = [x] inOrder (Node root left right) = inOrder left ++ [root] ++ inOrder right I'd like to write an in-order function that can have side effects. I achieved that with: inOrderM :: (Show x, Monad m) => (x -> m a) -> Tree x -> m () inOrderM f (Empty) = return () inOrderM f (Leaf y) = f y >> return () inOrderM f (Node root left right) = inOrderM f left >> f root >> inOrderM f right -- print tree in order to stdout inOrderM print tree This works fine, but it seems repetitive - the same logic is already present in inOrder and my experience with Haskell leads me to believe that I'm probably doing something wrong if I'm writing a similar thing twice. Is there any way that I can write a single function inOrder that can take either pure or monadic functions?
