• Identifier for win64 configuration in Qmake

  - by Tuminoid

  Is there a "win64" identifier in Qmake project files? Qt Qmake advanced documentation does not mention other than unix / macx / win32. So far I've tried using: win32:message("using win32") win64:message("using win64") amd64:message("using amd64") The result is always "using win32". Must I use a separate project-file for x32 and x64 projects, so they would compile against correct libraries? Is there any other way to identify between 32-bit and 64-bit environments?

• How to remember checkbox input in PHP Forms

  - by Derek

  For usability purposes I like to set up my form fields this way: <?php $username = $_POST['username']; $message = $_POST['message']; ?> <input type="text" name="username" value="<?php echo $username; ?>" /> <textarea name="message"><?php echo $message; ?></textarea> This way if the user fails validation, the form input he entered previously will still be there and there would be no need to start from scratch. My problem is I can't seem to keep check boxes selected with the option that the user had chosen before (when the page refreshes after validation fails). How to do this?

• Azure Mobile Services: available modules

  - by svdoever

  Azure Mobile Services has documented a set of objects available in your Azure Mobile Services server side scripts at their documentation page Mobile Services server script reference. Although the documented list is a nice list of objects for the common things you want to do, it will be sooner than later that you will look for more functionality to be included in your script, especially with the new provided feature that you can now create your custom API’s. If you use GIT it is now possible to add any NPM module (node package manager module, say the NuGet of the node world), but why include a module if it is already available out of the box. And you can only use GIT with Azure Mobile Services if you are an administrator on your Azure Mobile Service, not if you are a co-administrator (will be solved in the future). Until now I did some trial and error experimentation to test if a certain module was available. This is easiest to do as follows:   Create a custom API, for example named experiment. In this API use the following code: exports.get = function (request, response) { var module = "nonexistingmodule"; var m = require(module); response.send(200, "Module '%s' found.", module); }; You can now test your service with the following request in your browser: https://yourservice.azure-mobile.net/api/experiment If you get the result: {"code":500,"error":"Error: Internal Server Error"} you know that the module does not exist. In your logs you will find the following error: Error in script '/api/experiment.json'. Error: Cannot find module 'nonexistingmodule' [external code] atC:\DWASFiles\Sites\yourservice\VirtualDirectory0\site\wwwroot\App_Data\config\scripts\api\experiment.js:3:13[external code] If you require an existing (undocumented) module like the OAuth module in the following code, you will get success as a result: exports.get = function (request, response) { var module = "oauth"; var m = require(module); response.send(200, "Module '" + module + "' found."); }; If we look at the standard node.js documentation we see an extensive list of modules that can be used from your code. If we look at the list of files available in the Azure Mobile Services platform as documented in the blog post Azure Mobile Services: what files does it consist of? we see a folder node_modules with many more modules are used to build the Azure Mobile Services functionality on, but that can also be utilized from your server side node script code: apn - An interface to the Apple Push Notification service for Node.js. dpush - Send push notifications to Android devices using GCM. mpns - A Node.js interface to the Microsoft Push Notification Service (MPNS) for Windows Phone. wns - Send push notifications to Windows 8 devices using WNS. pusher - Node library for the Pusher server API (see also: http://pusher.com/) azure - Windows Azure Client Library for node. express - Sinatra inspired web development framework. oauth - Library for interacting with OAuth 1.0, 1.0A, 2 and Echo. Provides simplified client access and allows for construction of more complex apis and OAuth providers. request - Simplified HTTP request client. sax - An evented streaming XML parser in JavaScript sendgrid - A NodeJS implementation of the SendGrid Api. sqlserver – In node repository known as msnodesql - Microsoft Driver for Node.js for SQL Server. tripwire - Break out from scripts blocking node.js event loop. underscore - JavaScript's functional programming helper library. underscore.string - String manipulation extensions for Underscore.js javascript library. xml2js - Simple XML to JavaScript object converter. xmlbuilder - An XML builder for node.js. As stated before, many of these modules are used to provide the functionality of Azure Mobile Services platform, and in general should not be used directly. On the other hand, I needed OAuth badly to authenticate to the new v1.1 services of Twitter, and was very happy that a require('oauth') and a few lines of code did the job. Based on the above modules and a lot of code in the other javascript files in the Azure Mobile Services platform a set of global objects is provided that can be used from your server side node.js script code. In future blog posts I will go into more details with respect to how this code is built-up, all starting at the node.js express entry point app.js.

  - by Dmitry

  Hi, The question is: how to add news via FBConnect?? I have the following code: NSString *newsBody = @"[{\"message\": \"News message\" }]"; NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObject:newsBody forKey:@"news"]; [[FBRequest requestWithDelegate:self] call:@"facebook.dashboard.addnews" params:params dataParam:nil]; After I sent the request I received the success responce. But I can't see the new news in the facebook account!! Also, I tried to add full info into news parameter (http://wiki.developers.facebook.com/index.php/Dashboard.addNews):: NSString *newsBody = @"[{\"message\": \"News message\",\"action_link\": {\"text\": \"link text\", \"href\": \"http: //google.com\"} }]"; But this request returns error :( Thanks in advance!

• How do I close a database connection in a WCF service?

  - by Dan

  I have been unable to find any documentation on properly closing database connections in WCF service operations. I have a service that returns a streamed response through the following method. public virtual Message GetData() { string sqlString = BuildSqlString(); SqlConnection conn = Utils.GetConnection(); SqlCommand cmd = new SqlCommand(sqlString, conn); XmlReader xr = cmd.ExecuteXmlReader(); Message msg = Message.CreateMessage( OperationContext.Current.IncomingMessageVersion, GetResponseAction(), xr); return msg; } I cannot close the connection within the method or the streaming of the response message will be terminated. Since control returns to the WCF system after the completion of that method, I don't know how I can close that connection afterwards. Any suggestions or pointers to additional documentation would be appreciated. Dan

• Extreme Optimization – Numerical Algorithm Support

  - by JoshReuben

  Function Delegates Many calculations involve the repeated evaluation of one or more user-supplied functions eg Numerical integration. The EO MathLib provides delegate types for common function signatures and the FunctionFactory class can generate new delegates from existing ones. RealFunction delegate - takes one Double parameter – can encapsulate most of the static methods of the System.Math class, as well as the classes in the Extreme.Mathematics.SpecialFunctions namespace: var sin = new RealFunction(Math.Sin); var result = sin(1); BivariateRealFunction delegate - takes two Double parameters: var atan2 = new BivariateRealFunction (Math.Atan2); var result = atan2(1, 2); TrivariateRealFunction delegate – represents a function takes three Double arguments ParameterizedRealFunction delegate - represents a function taking one Integer and one Double argument that returns a real number. The Pow method implements such a function, but the arguments need order re-arrangement: static double Power(int exponent, double x) { return ElementaryFunctions.Pow(x, exponent); } ... var power = new ParameterizedRealFunction(Power); var result = power(6, 3.2); A ComplexFunction delegate - represents a function that takes an Extreme.Mathematics.DoubleComplex argument and also returns a complex number. MultivariateRealFunction delegate - represents a function that takes an Extreme.Mathematics.LinearAlgebra.Vector argument and returns a real number. MultivariateVectorFunction delegate - represents a function that takes a Vector argument and returns a Vector. FastMultivariateVectorFunction delegate - represents a function that takes an input Vector argument and an output Matrix argument – avoiding object construction  The FunctionFactory class RealFromBivariateRealFunction and RealFromParameterizedRealFunction helper methods - transform BivariateRealFunction or a ParameterizedRealFunction into a RealFunction delegate by fixing one of the arguments, and treating this as a new function of a single argument. var tenthPower = FunctionFactory.RealFromParameterizedRealFunction(power, 10); var result = tenthPower(x); Note: There is no direct way to do this programmatically in C# - in F# you have partial value functions where you supply a subset of the arguments (as a travelling closure) that the function expects. When you omit arguments, F# generates a new function that holds onto/remembers the arguments you passed in and "waits" for the other parameters to be supplied. let sumVals x y = x + y     let sumX = sumVals 10     // Note: no 2nd param supplied.     // sumX is a new function generated from partially applied sumVals.     // ie "sumX is a partial application of sumVals." let sum = sumX 20     // Invokes sumX, passing in expected int (parameter y from original)  val sumVals : int -> int -> int val sumX : (int -> int) val sum : int = 30 RealFunctionsToVectorFunction and RealFunctionsToFastVectorFunction helper methods - combines an array of delegates returning a real number or a vector into vector or matrix functions. The resulting vector function returns a vector whose components are the function values of the delegates in the array. var funcVector = FunctionFactory.RealFunctionsToVectorFunction(     new MultivariateRealFunction(myFunc1),     new MultivariateRealFunction(myFunc2));  The IterativeAlgorithm<T> abstract base class Iterative algorithms are common in numerical computing - a method is executed repeatedly until a certain condition is reached, approximating the result of a calculation with increasing accuracy until a certain threshold is reached. If the desired accuracy is achieved, the algorithm is said to converge. This base class is derived by many classes in the Extreme.Mathematics.EquationSolvers and Extreme.Mathematics.Optimization namespaces, as well as the ManagedIterativeAlgorithm class which contains a driver method that manages the iteration process.  The ConvergenceTest abstract base class This class is used to specify algorithm Termination , convergence and results - calculates an estimate for the error, and signals termination of the algorithm when the error is below a specified tolerance. Termination Criteria - specify the success condition as the difference between some quantity and its actual value is within a certain tolerance – 2 ways: absolute error - difference between the result and the actual value. relative error is the difference between the result and the actual value relative to the size of the result. Tolerance property - specify trade-off between accuracy and execution time. The lower the tolerance, the longer it will take for the algorithm to obtain a result within that tolerance. Most algorithms in the EO NumLib have a default value of MachineConstants.SqrtEpsilon - gives slightly less than 8 digits of accuracy. ConvergenceCriterion property - specify under what condition the algorithm is assumed to converge. Using the ConvergenceCriterion enum: WithinAbsoluteTolerance / WithinRelativeTolerance / WithinAnyTolerance / NumberOfIterations Active property - selectively ignore certain convergence tests Error property - returns the estimated error after a run MaxIterations / MaxEvaluations properties - Other Termination Criteria - If the algorithm cannot achieve the desired accuracy, the algorithm still has to end – according to an absolute boundary. Status property - indicates how the algorithm terminated - the AlgorithmStatus enum values:NoResult / Busy / Converged (ended normally - The desired accuracy has been achieved) / IterationLimitExceeded / EvaluationLimitExceeded / RoundOffError / BadFunction / Divergent / ConvergedToFalseSolution. After the iteration terminates, the Status should be inspected to verify that the algorithm terminated normally. Alternatively, you can set the ThrowExceptionOnFailure to true. Result property - returns the result of the algorithm. This property contains the best available estimate, even if the desired accuracy was not obtained. IterationsNeeded / EvaluationsNeeded properties - returns the number of iterations required to obtain the result, number of function evaluations.  Concrete Types of Convergence Test classes SimpleConvergenceTest class - test if a value is close to zero or very small compared to another value. VectorConvergenceTest class - test convergence of vectors. This class has two additional properties. The Norm property specifies which norm is to be used when calculating the size of the vector - the VectorConvergenceNorm enum values: EuclidianNorm / Maximum / SumOfAbsoluteValues. The ErrorMeasure property specifies how the error is to be measured – VectorConvergenceErrorMeasure enum values: Norm / Componentwise ConvergenceTestCollection class - represent a combination of tests. The Quantifier property is a ConvergenceTestQuantifier enum that specifies how the tests in the collection are to be combined: Any / All  The AlgorithmHelper Class inherits from IterativeAlgorithm<T> and exposes two methods for convergence testing. IsValueWithinTolerance<T> method - determines whether a value is close to another value to within an algorithm's requested tolerance. IsIntervalWithinTolerance<T> method - determines whether an interval is within an algorithm's requested tolerance.

• Vector of pointers to base class, odd behaviour calling virtual functions

  - by Ink-Jet

  I have the following code #include <iostream> #include <vector> class Entity { public: virtual void func() = 0; }; class Monster : public Entity { public: void func(); }; void Monster::func() { std::cout << "I AM A MONSTER" << std::endl; } class Buddha : public Entity { public: void func(); }; void Buddha::func() { std::cout << "OHMM" << std::endl; } int main() { const int num = 5; // How many of each to make std::vector<Entity*> t; for(int i = 0; i < num; i++) { Monster m; Entity * e; e = &m; t.push_back(e); } for(int i = 0; i < num; i++) { Buddha b; Entity * e; e = &b; t.push_back(e); } for(int i = 0; i < t.size(); i++) { t[i]->func(); } return 0; } However, when I run it, instead of each class printing out its own message, they all print the "Buddha" message. I want each object to print its own message: Monsters print the monster message, Buddhas print the Buddha message. What have I done wrong?

• Help needed with InvokeRequired for Web.UI

  - by Ali

  I have a multi-threaded application in C# which tries to write to a TextBox in a Windows.Forms created by another thread. As threads cannot modify what has not been created by them, I was using InvokeRequired as shown on the code below, to solve this problem. public delegate void MessageDelegate(Communication message); void agent_MessageReceived(Communication message) { if (InvokeRequired) { BeginInvoke(new MessageDelegate(agent_MessageReceived), new object[] { message }); } else { TextBox1.Text += message.Body; } } Now I need to do the same for a TextBox in an ASP.NET app, but apparently neither InvokeRequired nor BeginInvoke exist for TextBox in a Web.UI. What can I do?

• JQuery UI sortable: restore position based on some condition

  - by dafi

  I call sortable.stop() to make an ajax call to store some data after drag&drop operation. When the ajax call returns an error (application logic error or net problem) I want to move the dragged element to its original/start position, how can I achieve it? The scenario should be user drags A to B the sortable.stop() event is called, it triggers an ajax call the ajax call returns an error inside the stop() event we get the ajax error move A to its original position user again move A to B everything is ok A remains in its new position in B Steps 6-8 are shown to clarify a successive drag can be done and previous error must be forgotten

• Informational messages returned with WCF involved

  - by DT

  This question is about “informational messages” and having them flow from a “back end” to a “front end” in a consistent manner. The quick question is “how do you do it”? Background: Web application using WCF to call back end services. In the back end service a “message” may occur. Now, the reason for this “message” may be a number of reasons, but for this discussion let’s assume that a piece of data was looked at and it was determined that the caller should be given back some information regarding it. This “informational” message may occur during a save and also may occur during retrieval of information. Again, the message is not what is important here, but the fact that there is some informational messages to give back under a number of different scenarios. From a team perspective we all want to return these “messages” in a standard way all of the time. Now, in the past this “standard way” has been done different ways by different people. Here are some possibilities: 1) Every operation has a “ref” parameter at the end that contains these messages 2) Every method returns these messages… however, this only kind of works for “Save” methods as one would think that “Retrieve” methods should return actual data and not messages 3) Some approach using the call context so as to not "pollute" all message signatures with something; however, with WCF in the picture this complicates things. That is, going back to the messages go on a header? Question: Back to my question then… how are others returning “messages” such as what was described above back through tiers of an application, over WCF and back to the caller?

• Massive SQL issue shutting down our site.

  - by Pselus

  Our website has started timing out like crazy today. All of our clients are finding it unusable. The only error we can seem to trace down as a potential problem is this: SQLAllocHandle on SQL_HANDLE_DBC failed Error ASP Description Error Category Microsoft OLE DB Provider for ODBC Drivers I have no idea what it means or how to go about fixing it. Anyone ever encountered this error before? Currently, you can log in to our site, but then once you go to do anything else, you find yourself logged out or nothing happens. We have a lot of Ajax going on so the "nothing happens" probably has to do with the Ajax pages not loading properly due to logouts and so nothing displays to the user. Like I said, I'm at a loss. Anyone have any advice on this error?

• PHP jQuery Long Polling Chat Application

  - by Tejas Jadhav

  I've made a simple PHP jQuery Chat Application with Short Polling (AJAX Refresh). Like, every 2 - 3 seconds it asks for new messages. But, I read that Long Polling is a better approach for Chat applications. So, I went through some Long Polling scripts. I made like this: Javascript: $("#submit").click(function(){ $.ajax({ url: 'chat-handler.php', dataType: 'json', data: {action : 'read', message : 'message'} }); }); var getNewMessage = function() { $.ajax({ url: 'chat-handler.php', dataType: 'json', data: {action : 'read', message : 'message'}, function(data){ alert(data); } }); getNewMessage(); } $(document).ready(getNewMessage); PHP <?php $time = time(); while ((time() - $time) < 25) { $data = $db->getNewMessage (); if (!empty ($data)) { echo json_encode ($data); break; } usleep(1000000); // 1 Second } ?> The problem is, once getNewMessage() starts, it executes unless it gets some response (from chat-handler.php). It executes recursively. But if someone wants to send a message in between, then actually that function ($("#submit").click()) never executes as getNewMessage() is still executing. So is there any workaround?

• Jquery display image problem

  Hello, I have PHP page where users can upload photos (using Ajax & PHP script). Those uploaded photos (thumbs) are shown after upload in DIV below upload field. Then, after hitting send button I want to clone that DIV at that same page at message board, bellow other messages with or without uploaded photos. When I try to do that with: var pht = $("#photos").clone().addClass('p_pht'); and try to display sent photos bellow sent message like this: $("div#wall").append('<div class=msg>'+ message +'</div><div class=n_pht>'+ pht +'</div>'); I get Jquery error message "[object Object]" in place where the photos should be displaying.

• Rails escape_javascript creates invalid JSON by escaping single quotes

  - by Arrel

  The escape_javascript method in ActionView escapes the apostrophe ' as backslash apostrophe \', which gives errors when parsing as JSON. For example, the message "I'm here" is valid JSON when printed as: {"message": "I'm here"} But, <%= escape_javascript("I'm here") %> outputs "I\'m here", resulting in invalid JSON: {"message": "I\'m here"} Is there a patch to fix this, or an alternate way to escape strings when printing to JSON?

• How do I close a database connection being used to produce a streaming result in a WCF service?

  - by Dan

  I have been unable to find any documentation on properly closing database connections in WCF service operations. I have a service that returns a streamed response through the following method. public virtual Message GetData() { string sqlString = BuildSqlString(); SqlConnection conn = Utils.GetConnection(); SqlCommand cmd = new SqlCommand(sqlString, conn); XmlReader xr = cmd.ExecuteXmlReader(); Message msg = Message.CreateMessage( OperationContext.Current.IncomingMessageVersion, GetResponseAction(), xr); return msg; } I cannot close the connection within the method or the streaming of the response message will be terminated. Since control returns to the WCF system after the completion of that method, I don't know how I can close that connection afterwards. Any suggestions or pointers to additional documentation would be appreciated.

• Generate a Version.java file in Maven

  - by Ralph

  I have a Java project that I build using an Ant script. I am trying to convert the project to Maven. One of the tasks generates a Java source file called Version.java that contains a static String representation of the compilation timestamp, as follows: package com.foo.bar; public final class Version { public static String VERSION="100301.1046"; } The Ant task is very simple: <target name="version" depends="init" description="Create Version.java"> <echo file="src/${package.dir}/Version.java" message="package ${package.name};${line.separator}" /> <echo file="src/${package.dir}/Version.java" append="true" message="public final class Version {${line.separator}" /> <echo file="src/${package.dir}/Version.java" append="true" message=" public static String VERSION=&quot;${buildtime}&quot;;${line.separator}" /> <echo file="src/${package.dir}/Version.java" append="true" message="}${line.separator}" /> <echo message="BUILD ${buildtime}" /> </target> Is it possible to do something similar in Maven, using generate-sources, or some other simple method?

• To detect if the user is closing the IE browser apart from onunload event, as it is triggerred when

  - by AndAars

  hi, After being through numerous forums available on the net for last 5 days, I am still not able to completely track down the browser close event. My requirement is to generate a popup message, when user tries to close the browser. I have called my javascript function on body 'onbeforeunload' event. And I have hardcoded the conditions to check the mouse-coordinates for the red 'X' buton of browser, refresh, File-close or Alt-F4. My code works fine when browser window is Maximized, but fails if we shrink it after a limit. Please help me, if some body has already found the solution to a similar problem. Thank you. Aggregated Responses of OP Ok, just tell me if it is possible to detect if a user has clicked on the Refresh button of the browser. Also, Refresh can be triggered by Right-click - Refresh or Ctrl-R. My requirement is to make a variable false on Refresh. I am just able to do it on F5, but all other ways are still out of my reach. The same would be applied to Back buton. Hi ppl, Thanks for all who replied atleast. I have talked to my seniors regarding this and they have now understood and have compromised with the browser menu buttons. So now my task has become easy. Now, I am using a variable and making it true by default. As, I mentioned earlier I just have to catch the onbeforeunload and popup a message when user tries to leave. The message will not popup when user is navigating to other pages, as I have made the variable as false on all the links of my page using following piece of code: document.onclick = function() { //To check if user is navigating from the page by clicking on a hyperlink. if (event.srcElement.tagName == 'A') blnShowMsg = false; //To not popup the warning message else blnShowMsg = true; //To popup the warning message } In my case still the message is shown when user does Refresh, back or goes to any link in Favorites, etc. Thanks buddy, but I have already gone through that and didn't find much help there too. My seniors are not happy with that solution as putting a flag on evry link of my application is a complicated job and they fear of breaking the application. Any other suggestions would be appreciated. Thanks once again. Is there no one who can think of a solution here!!! where are all the experts???
