  I'm trying to send a email notification to the user from my Facebook application. I'm trying to use the FaceBook JavaScript API function notifications_sendEmail(Array recipients, String subject, String text, String fbml, Object onRequestCompleted) I can understand the first four parameters. But what's the usage of the last parameter 'onRequestCompleted'. The Doc says it's the call back function. But, what if I do not want to execute a call back function? In this case, what will be a valid values to the parameter onRequestCompleted?

• 2 Classes need each other declared C++

  - by Prodigga

  I have a "Game" class which holds all the games settings and manages the game. I have a "Grid" class which is the grid the game is played on. The "Game" class initializes a "Grid" object as one of its members (passing itself ("this") as one of the parameters for "Grid"s constructor).. The "Grid" object therefor needs to deal with a "Game*" pointer. To do this it needs to know what "Game" is; i need to declare it before "Grid". But "Game" uses "Grid"...so it also needs "Grid" declared before it. so confused on how to include headers/etc correctly here..

• Questions regarding PHPUnit mock feature

  - by Andree

  Can someone provide me a reference to a good PHPUnit mock guide? The one in the official documentation doesn't seem to be detailed enough. I need to know about the following: 1) How to expect multiple calls to a mock object's method, but each return a different sets of value? $tableMock->expects($this->exactly(2)) ->method('find') ->will($this->returnValue(2)); // I need the second call to return different value 2) How to expect a call to a mock object's method with multiple parameters?

• Trying to get JQuery Autocomplete working on Asp.Net page.

  - by JasonMHirst

  Can someone shed some light on the problem please: I have the following: $(document).ready(function () { $("#txtFirstContact").autocomplete({url:'http://localhost:7970/Home/FindSurname' }); }); On my Asp.Net page. The http request is a function on an MVC Controller and that code is here: Function FindSurname(ByVal surname As String, ByVal count As Integer) Dim sqlConnection As New SqlClient.SqlConnection sqlConnection.ConnectionString = My.Settings.sqlConnection Dim sqlCommand As New SqlClient.SqlCommand sqlCommand.CommandText = "SELECT ConSName FROM tblContact WHERE ConSName LIKE '" & surname & "%'" sqlCommand.Connection = sqlConnection Dim ds As New DataSet Dim da As New SqlClient.SqlDataAdapter(sqlCommand) da.Fill(ds, "Contact") sqlConnection.Close() Dim contactsArray As New List(Of String) For Each dr As DataRow In ds.Tables("Contact").Rows contactsArray.Add(dr.Item("ConSName")) Next Return Json(contactsArray, JsonRequestBehavior.AllowGet) End Function As far as I'm aware, the Controller is returning JSON data, however I don't know if the Function Parameters are correct, or indeed if the format returned is interprettable by the AutoComplete plugin. If anyone can assist in the matter I'd really appreciate it.

  I am using google site to retrieve weather information , I want to find values between XML tags. Following code give me weather condition of a city , but I am unable to obtain other parameters such as temperature and if possible explain working of split function implied in the code: import urllib def getWeather(city): #create google weather api url url = "http://www.google.com/ig/api?weather=" + urllib.quote(city) try: # open google weather api url f = urllib.urlopen(url) except: # if there was an error opening the url, return return "Error opening url" # read contents to a string s = f.read() # extract weather condition data from xml string weather = s.split("<current_conditions><condition data=\"")[-1].split("\"")[0] # if there was an error getting the condition, the city is invalid if weather == "<?xml version=": return "Invalid city" #return the weather condition return weather def main(): while True: city = raw_input("Give me a city: ") weather = getWeather(city) print(weather) if __name__ == "__main__": main() Thank You

• vb.net Is there a simple way to add a sound to a button click

  - by user867621

  Is there a simple way of doing this I found this online and I am getting an error Declare Function apisndPlaySound Lib "winmm" Alias "sndPlaySoundA" _ (ByVal filename As String, ByVal snd_async As Long) As Long Function PlaySound(ByVal sWavFile As String) ' Purpose: Plays a sound. ' Argument: the full path and file name. If apisndPlaySound(sWavFile, 1) = 0 Then MsgBox("The Sound Did Not Play!") End If End Function A call to PInvoke function 'WindowsApplication3!WindowsApplication3.Module1::apisndPlaySound' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.

• Accessing typedef from the instance

  - by piotr

  As in stl containers, why can't we access a typedef inside the class from the class instance? Is there a particular insight into this? When value_type was a template parameter it could help making more general code if there wasn't the need to specify the template parameters as in vector::value_type Example: class T { public: typedef int value_type; value_type i; }; T t; T::value_type i; // ok t.value_type i; // won't work

• Watir changes highline's "ask" method

  - by grundic

  Hello! I've encoutered some strange functionality, when using Watir and Highline together. Here is simple example: require 'highline/import' comp = ask("Company? ") { |q| q.default = "MySuperCompany" } puts comp require 'watir' comp = ask("Company? ") { |q| q.default = "MySuperCompany" } puts comp Here is an output: Company? |MySuperCompany| MySuperCompany [Company? ] => Company? Maybe it's a bug? I've also found in documentation for highline, that If @question is set before ask() is called, parameters are ignored and that object (must be a HighLine::Question) is used to drive the process instead. Sorry, I'm not a ruby guru :-(

• Passing arguments to anonymous inner classes

  - by synic

  I'm trying to make an API library for our web services, and I'm wondering if it's possible to do something like this: abstract class UserRequest(val userId: Int) { def success(message: String) def error(error: ApiError) } api.invokeRequest(new UserRequest(121) { override def success(message: String) = { // handle success } override def error(error: ApiError) = { // handle the error } } I'm talking about passing parameters to the anonymous inner class, and also overriding the two methods. I'm extremely new to Scala, and I realize my syntax might be completely wrong. I'm just trying to come up with a good design for this library before I start coding it. I'm willing to take suggestions for this, if I'm doing it the completely wrong way, or if there's a better way. The idea is that the API will take some sort of request object, use it to make a request in a thread via http, and when the response has been made, somehow signal back to the caller if the request was a success or an error. The request/error functions have to be executed on the main thread.

• Creating Visual Studio Templates

  - by vanja.

  I'm looking to create a Visual Studio 2008 template that will create a basic project and based on remove certain files/folders based on options the user enters. Right now, I have followed some tutorials online which have let me create the form to query the user and pass the data into an IWizard class, but I don't know what to do from there. The tutorials provide a sample to do some simple substitution: code: Form1 form = new Form1(); DialogResult dlg = form.ShowDialog(); if (dlg == DialogResult.OK) { foreach (KeyValuePair<string, string> pair in form.Parameters) { if (!replacementsDictionary.ContainsKey(pair.Key)) replacementsDictionary.Add(pair.Key, pair.Value); else replacementsDictionary[pair.Key] = pair.Value; } } form.Close(); but I'm looking to selectively include files based on the user settings, and if possible, selectively include code sections in a file based on settings. Is there a clever way to do this, or will I manually have to delete project files in the IWizard:ProjectFinishedGenerating()?

• Passing variables to functions in Python

  - by brno792

  Im writing test scripts in python for selenium web testing. How do I pass parameters through a python function to call in a later function? I first have a login test function. Then I have a new user registration function. Im trying to pass the Username and Password I use in the registration function to the testLogin function that I call inside the testRegister function. This is my python code: userName = "admin" password = "admin" #pass username and password variables to this function def testLogin(userName,password): browser = webdriver.Firefox() browser.get("http://url/login") element = browser.find_element_by_name("userName") element.send_keys(userName) element = browser.find_element_by_name("userPassword") element.send_keys(password) element.send_keys(Keys.RETURN) browser.close() # test registration def testRegister(): browser = webdriver.Firefox() browser.get("http://url/register") #new username variable newUserName = "test" element = browser.find_element_by_name("regUser") element.send_keys(newUserName) #new password variable newUserPassword = "test" element = browser.find_element_by_name("regPassword") element.send_keys(newUserPassword) # #now test if user is registered, I want to call testLogin with the test user name and pw. testLogin(newUserName,newUserPassword) browser.close()

• Problem with Clojure function

  - by Bozhidar Batsov

  Hi, everyone, I've started working yesterday on the Euler Project in Clojure and I have a problem with one of my solutions I cannot figure out. I have this function: (defn find-max-palindrom-in-range [beg end] (reduce max (loop [n beg result []] (if (>= n end) result (recur (inc n) (concat result (filter #(is-palindrom? %) (map #(* n %) (range beg end))))))))) I try to run it like this: (find-max-palindrom-in-range 100 1000) and I get this exception: java.lang.Integer cannot be cast to clojure.lang.IFn [Thrown class java.lang.ClassCastException] which I presume means that at some place I'm trying to evaluate an Integer as a function. I however cannot find this place and what puzzles me more is that everything works if I simply evaluate it like this: (reduce max (loop [n 100 result []] (if (>= n 1000) result (recur (inc n) (concat result (filter #(is-palindrom? %) (map #(* n %) (range 100 1000)))))))) (I've just stripped down the function definition and replaced the parameters with constants) Thanks in advance for your help and sorry that I probably bother you with idiotic mistake on my part. Btw I'm using Clojure 1.1 and the newest SLIME from ELPA.

• Visual Studio 2008 awful performance

  - by Nima

  Hi, I have ported a piece of C++ code, that works out of core, from Linux(Ubuntu) to Windows(Vista) and I realized that it works about 50times slower on VS2008! I removed all the out of core parts and now I just have a piece of code that has nothing to do with the hard disk. I set compiler parameters to O2 in Project Properties but still get about 10times slower than g++ in linux! Does anybody have an idea why it is this much slower under VS? I really appreciate any kind of hint! Thanks,

• Google Social Graph API, working as intended?

  - by pns

  Hey, I'm experiencing some problems with Google's social graph API. It seems that for some parameters passed to 'otherme' nothing is returned. I'll use Robert Scoble's profiles as an example (as he's a guy sure to be everywhere on the web). If I query: http://socialgraph.apis.google.com/otherme?q=http://twitter.com/scobleizer&pretty=1 I get results, as expected. However, if I query: http://socialgraph.apis.google.com/otherme?q=http://delicious.com/scobleizer&pretty=1 Nothing is returned, even though 'http://delicious.com/scobleizer' is listed in the previous results... Any thoughts? Thanks

• Unable to execute an oracle update statement within perl

• How can I access and modify objects inside frames with AS3 in a permanent way?

  - by curro

  I have a MovieClip symbol created with flash in a fla file library. There is a textfield in frame one of this movieclip's timeline . There is another frame in the movieclip timeline. There is a custon class definition for this symbol. It is a flipping card in a memory game. I access the textfield by going to frame 2 (gotoAndStop(2)) and setting the textfield's text property ( this.field.text = "hello" ). However if I go to frame 1 and then return to frame 2, the text becomes the original one in the library's symbol. I have to modify the text propery again in a showFace method I've written. Besides, I cannot pass parameters in the constructor because it is a symbol in the library and that would give errors. I find this behaviour of flash extremely weird. Is there a way I can set properties inside frames permanently? Thank you

• Anonymous types based in Interface

  - by Bhaskar

  Can I create anonymous implementations of an interface , in a way similar to the way delegate() { // type impl here , but not implementing any interface} Something on the lines of new IInterface() { // interface methods impl here } The situations where I see them to be useful are for specifying method parameters which are interface types, and where creating a class type is too much code. For example , consider like this : public void RunTest() { Cleanup(delegate() { return "hello from anonymous type"; }); } private void Cleanup(GetString obj) { Console.WriteLine("str from delegate " + obj()); } delegate string GetString(); how would this be achieved if in the above code , the method Cleanup had an interface as a parameter , without writing a class definition ? ( I think Java allows expressions like new Interface() ... )

• CLI design and implementation?

  - by Majid

  I am developing a time management tool for my personal use. I prefer using keyboard over mouse, and on the interface have a general purpose text box which will act like a command line. I have just started thinking about what commands I need, what to use for the command names, how to pass in switches and parameters, and so forth. I wonder if some of you have come across a good read along these lines; something that describes the choices you have for designing a cli, and how those affect the complexity of the interpreter, and extendability of the commands. It makes no difference if the descriptions are language-specific or in general terms. However, my implementation will be with javascript. Thank you.

• Workflow Foundation: How to create Recieve activity with custom message in xaml designer?

  - by Petr Felzmann

  I need to have Recieve activity which can receive my custom data. I found examples, but all use coded workflows like such public class ProcessRequest : Activity { public ProcessRequest() { Variable<MyData> request = new Variable<MyData> { Name = "request" }; Receive receiveRequest = new Receive { ServiceContractName = "IProcessRequest", OperationName = "Foo", CanCreateInstance = true, Content = ReceiveContent.Create(new OutArgument<MyData>(request)) }; } } The main point is that Recieve.Content property. It is not clear for me how I can do it in XAML designer. What I have to set in the dialog of the Content property - Message or Parameters and what to set inside those options? Thanks for the light!

• PHP code cannot see query string param on return in Facebook oAuth flow

  - by TMC

  I am doing some integration with Facebook Open Graph using their oAuth flow and having issues with parsing query string parameters they return. On my callback URL, they pass back an "access_token" parameter with a hash (#). so the callback would be: http://mydomain.com/callback.php#access_token=foobar123 where foobar123 is my access token I'm trying to parse out. However, no matter what I do, my PHP code cannot see if and I've done every debug trick I know (even using phpinfo() to go through everything). The URL is stated only as http://mydomain.com/callback.php. It's as if the rest of the URL isn't really there! This code returns nothing: $token = $_REQUEST['access_token']; Any help would be greatly appreciated... I'm obviously missing something simple.

• spring mvc nested model validation

  - by hguser

  I have two models : User,Project public class Project{ private int id; @NotEmpty(message="Project Name can not be empty") private String name; private User manager; private User operator; //getter/setter omitted } public class User{ private int id; private String name; //omit other properties and getter/setter } Now, when I create a new Project, I will submit the following parameters to ProjectController: projects?name=jhon&manager.id=1&operator.id=2... Then I will create a new Project object and insert it to db. However I have to validate the id of the manager and operator is valid,that's to say I will validate that if there is matched id in the user table. So I want to know how to implement this kind of validation?

• Is there a way to determine the Variance of an Interface / Delegate in C# 4.0?

  - by BFree

  So now that we have generic Covariance and Contravariance on interfaces and delegates in C#, I was just curious if given a Type, you can figure out the covariance/contravariance of its generic arguments. I started trying to write my own implementation, which would look through all of the methods on a given type and see if the return types and or arguments match the types in the generic arguments. The problem is that even if I have this: public interface IFoo<T> { void DoSomething(T item); } using my logic, it LOOKS like it should be contravariant, but since we didn't actually specify: public interface IFoo<in T> { void DoSomething(T item); } (the in parameter) it isn't actually contravariant. Which leads to my question: Is there a way to determine the variance of generic parameters?

• strange results with /fp:fast

  - by martinus

  We have some code that looks like this: inline int calc_something(double x) { if (x > 0.0) { // do something return 1; } else { // do something else return 0; } } Unfortunately, when using the flag /fp:fast, we get calc_something(0)==1 so we are clearly taking the wrong code path. This only happens when we use the method at multiple points in our code with different parameters, so I think there is some fishy optimization going on here from the compiler (Microsoft Visual Studio 2008, SP1). Also, the above problem goes away when we change the interface to inline int calc_something(const double& x) { But I have no idea why this fixes the strange behaviour. Can anyone explane this behaviour? If I cannot understand what's going on we will have to remove the /fp:fastswitch, but this would make our application quite a bit slower.
