  • json call with C#

    - by Vaccano
    I am trying to make a json call using C#. I made a stab at creating a call, but it did not work: public bool SendAnSMSMessage(string message) { HttpWebRequest request = (HttpWebRequest) WebRequest.Create("http://api.pennysms.com/jsonrpc"); request.Method = "POST"; request.ContentType = "application/json"; string json = "{ \"method\": \"send\", "+ " \"params\": [ "+ " \"IPutAGuidHere\", "+ " \"[email protected]\", "+ " \"MyTenDigitNumberWasHere\", "+ " \""+message+"\" " + " ] "+ "}"; StreamWriter writer = new StreamWriter(request.GetRequestStream()); writer.Write(json); writer.Close(); return true; } Any advice on how to make this work would be appreciated.

  • Enter custom file name to be read ?

    - by ZaZu
    Hello, I want to allow users to type the name of any .txt file to be read/written. This is my code : printf("Enter .txt file name\n"); scanf("%s",&fname); FILE *inputf; inputf=fopen(&fname,"w"); Problem is this method does not work (having &fname) as a parameter. I can imagine its because C needs "filename.txt" for it work ... even if I enter for example : "custom.txt", the program returns an error of "Storage block not big enough for this operation" What is the correct method to accomplish this ? Im using C and im pretty much using basic commands .. (not too advanced) Thanks alot !!!

    - by flash
    public static MySingleton getInstance() { if (_instance==null) { synchronized (MySingleton.class) { _instance = new MySingleton(); } } return _instance; } 1.is there a flaw with the above implementation of the getInstance method? 2.What is the difference between the two implementations.? public static synchronized MySingleton getInstance() { if (_instance==null) { _instance = new MySingleton(); } return _instance; } I have seen a lot of answers on the singleton pattern in stackoverflow but the question I have posted is to know mainly difference of 'synchronize' at method and block level in this particular case.

  • Indexing with pointer C/C++

    - by Leavenotrace
    Hey I'm trying to write a program to carry out newtons method and find the roots of the equation exp(-x)-(x^2)+3. It works in so far as finding the root, but I also want it to print out the root after each iteration but I can't get it to work, Could anyone point out my mistake I think its something to do with my indexing? Thanks a million :) #include <stdio.h> #include <math.h> #include <malloc.h> //Define Functions: double evalf(double x) { double answer=exp(-x)-(x*x)+3; return(answer); } double evalfprime(double x) { double answer=-exp(-x)-2*x; return(answer); } double *newton(double initialrt,double accuracy,double *data) { double root[102]; data=root; int maxit = 0; root[0] = initialrt; for (int i=1;i<102;i++) { *(data+i)=*(data+i-1)-evalf(*(data+i-1))/evalfprime(*(data+i-1)); if(fabs(*(data+i)-*(data+i-1))<accuracy) { maxit=i; break; } maxit=i; } if((maxit+1==102)&&(fabs(*(data+maxit)-*(data+maxit-1))>accuracy)) { printf("\nMax iteration reached, method terminated"); } else { printf("\nMethod successful"); printf("\nNumber of iterations: %d\nRoot Estimate: %lf\n",maxit+1,*(data+maxit)); } return(data); } int main() { double root,accuracy; double *data=(double*)malloc(sizeof(double)*102); printf("NEWTONS METHOD PROGRAMME:\nEquation: f(x)=exp(-x)-x^2+3=0\nMax No iterations=100\n\nEnter initial root estimate\n>> "); scanf("%lf",&root); _flushall(); printf("\nEnter accuracy required:\n>>"); scanf("%lf",&accuracy); *data= *newton(root,accuracy,data); printf("Iteration Root Error\n "); printf("%d %lf \n", 0,*(data)); for(int i=1;i<102;i++) { printf("%d %5.5lf %5.5lf\n", i,*(data+i),*(data+i)-*(data+i-1)); if(*(data+i*sizeof(double))-*(data+i*sizeof(double)-1)==0) { break; } } getchar(); getchar(); free(data); return(0); }

  • Android RealViewSwitcher : How to start on second page?

    - by DarcCode
    i'm using RealViewSwitcher I got from this site. It works perfectly on my code, but I don't have any idea how to set the initial current screen to second or third screen. the method setCurrentScreen(int) doesn't affect anything and if I change the for loop inside the onLayout() method from for (int i = 0; i < count; i++) {...} into for (int i = 1; i < count; i++){...} It does starts in page two, but you can't go to page one. Any idea how to start on page two?

  • Java Authenticator on a per connection basis?

    - by Martijn Laarman
    I'm building an Eclipse plugin that talks to a REST interface which uses Basic Authentication. When the authentication fails I would like to popup my plugin's settings dialog and retry. Normally I could use the static Authenticator.setDefault() to setup an authenticator for all HttpURLConnection's for this, but since I am writing a plugin I don't want to overwrite Eclipse's default Authenticator (org.eclipse.ui.internal.net.auth); I thought of setting my custom Authenticator before loading and putting Eclipse's default back afterwards, but I imagine this will cause all sorts of race issues with multithreading so I quickly lost that notion. Google searches yield all sorts of results basically telling me it's not possible: The Java URLConnection API should have a setAuthenticator(Authenticator) method for making it easier to use this class in multi-threaded context where authentication is required. Source If applications contains few third party plugins and each plugin use its own Authenticator what we should do? Each invocation of "Authenticator.setDefault()" method rewrite previously defined Authenticator... Source Are there any different approaches that might help me overcome this issue?

  • Duel Masters game in Java

    - by Arun Ramasubramanian
    I was trying to make a Duel Masters card game in Java using BlueJ, and came up with a lot of ideas. However, I could not exactly figure out how to sort a deck on basis of the card names in the game. I have an array of Card objects(each has, as its instance variables: String name, int cost, int civ), and I want to sort them based on name. ie: if I have the cards "Pyrofighter Magnus", "Bazagazeal Dragon" and another "Pyrofighter Magnus" in the array, the cards should be sorted on basis of their names. I know that I could use compareTo(), but is there an easier method? Anyone? Remember, the method that sorts the cards should be a modifier.

  • Drawing a waveform in C#

    - by user488792
    Hi! I want to be able to display a WaveForm in C#, along with some simple features such as zooming and selection. I already have the data as a short[] of amplitude values. However, I am an amateur when it comes to hardcoding GUI. I have already found a possible helper class WaveFormClass that may help me achieve this but as a backup, I want to learn how to manually do it. So may I ask for some methods and possibly some links that will help? Thanks!

  • Rails: What's the suggested approach to retrieve xml from an outside source

    - by Syrahn
    Rails newbie (though long time programmer) here. I'm writing an test app that retrieves data from several outside sources (think Twitter, RSS feeds, etc.) and under certain circumstances, it stores that data in a db (or presents it to the user). The data model and the views are trivial. What I'm having difficulty with is making the actual xml HTTP call to the outside source and deserialize the xml response so I can query/use it in my controller/helper. What library/gem should I use to accomplish this? I tried looking this up around the net, but only came up with some article from 2006 which, knowing how fast Rails has developed, might well be completely deprecated. Your help is much appreciated.

  • Why is it possible to save entity but not delete if transactional annotation is set to readonly=true

    - by jakob
    Hello experts! My class is annotated with org.springframework.transaction.annotation.Transactional like this: @Transactional(readOnly = true) public class MyClass { I then have a dao class: @Override public void delete(final E entity) { getSession().delete(entity); } @Override public void save(final E entity) { getSession().saveOrUpdate(entity); } Then I have two methods in MyClass @Transactional(readOnly = false) public void doDelete(Entity entity){ daoImpl.delete(entity) } //@Transactional(readOnly = false) public void doSave(){ daoImpl.save(entity) } Saving and deleting works like a charm. But if I remove the @Transactional(readOnly = false) on doDelete method deletion stops working, Saving works with and without the method annotation. So my question is: WHY?

  • User class - 'load' data

    - by John
    <?php class User { private $id; private $username; public function __construct($id = null) { $this->id = $id; if (!is_null($this->id)) { $this->load(); } } public function load() { } } ?> In the 'load' method I am going to load all the information from the current user (id) But I wonder how is the best way to load all info. I could grab all data and then just assign all private variables, but I assume there must be another "cheaper" way to get all the data so I can use as such $this-variable; And not have to ASSIGN every single data row, I select in the load method. How?

  • control.focus() after selectedIndexChanged

    - by kyle
    I need to focus on a textbox after an item has been selected from a dropdownlist. I've tried control.focus() and setfocus(). The last thing I've tried was Set_Focus(dtbEffectiveDate.ClientID) inside the SelectedIndexChanged method with the folowing method. Protected Sub Set_Focus(ByVal ControlName As String) Dim strScript As String strScript = "<script language=javascript> window.setTimeout(""" + ControlName + ".focus();"",0); </script>" RegisterStartupScript("focus", strScript) End Sub I'm out of answers so any help would be awesome.

  • Searching for URL's Relative to Site Root in Javascript Source

    - by James
    Hi, I am working on a web site with several other developers and we have had problems where people commit JavaScript code with AJAX calls that use URL's relative to the site root. An example would be /Home/Index which will not work if the site is hosted in a virtual directory. To get round the problem we use a $.url() method to convert it to a full path, e.g. $("#container").load($.url("/Home/Index")) I am trying to write a unit test that will search each JavaScript file and find places where the $.url method is not being used. The only problem is that I cannot seem to write a regex expression to do this. I have tried the following: (?!\$\.url\()"(/\w*)+" But this does not work. I cannot find a way to say that I don't want the $.url in front. Does anyone know if this is possible? Note that I need regular expressions that are compatible with .NET Thanks.

  • What is the difference between these two ways of creating NSStrings?

    - by adame
    NSString *myString = @"Hello"; NSString *myString = [NSString stringWithString:@"Hello"]; I understand that using method (1) creates a pointer to a string literal that is defined as static memory (and cannot be deallocated) and that using (2) creates an NSString object that will be autoreleased. Is using method (1) bad? What are the major differences? Is there any instances where you would want to use (1)? Is there a performance difference? P.S. I have searched extensively on Stack Overflow and while there are questions on the same topic, none of them have answers to the questions I have posted above.

  • Restrict confirm message on page reload with f5

    - by Max
    In my JSP page I am using post method while submitting the page. So once I go from Page 1 to page 2. In Page 2, If I press F5 I am getting alert as "To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier." I knew this question is a bit sarcastic but please give me an Idea. I can't change my method from POST to GET because I need to send large amount of data. Thanks in advance... Edited: In my Page1.JSP I call onClick function in that function I call action as "/page2servlet.do". Now, In Java side I use Spring Framework. With MVC Object I return to page2.jsp. So where do the response.sendRedirect Fit.

  • Methods specific only to an instance? What are they called in Ruby?

    - by daremarkovic
    I know there are "instance methods", "class methods" but what are these types of methods called, for eg: s1 = "This is my STRING!" def s1.m1 downcase end p s1 # => "This is my STRING!" p s1.m1 # => "this is my string!" What type of method is the "m1" method called on the s1 "instance" of the "string" class? It's really weird because I didn't know this was possible at all if I try: s2 = "This is ANOTHER string" s2.m1 # => Won't work! Which kind of makes sense, but not sure why defining methods like m1 on instances on a class are useful at all.

  • Object initialization sequence in Objective-C

    - by Alex
    Hello everyone. The Cocoa framework has a convention to always call self = [super init] in the init method of an inherited class, because [super init] may return a new instance. What will happen if I do this? @interface MyClass : NSObject /* or any other class */ { int ivar_; } @end @implementation MyClass - (id)init { ivar_ = 12345; if ((self = [super init])) { NSLog(@"ivar_'s value is %d", ivar_); } return self; } @end In the case when [super init] returns a new instance, what will I see in the console? ivar_'s value is 0? I can't think of a way to check this myself, because I don't know which class may return a new instance from its init method. Also, can't seem to find explicit clarification for this scenario in the docs. Could anyone help me out? Thanks!
