• How to use/manipulate return value from nested boost::bind

  - by JQ

  I have two functions: 1. A & DataSource(); 2. void DataConsumer( A * ); What I want to achieve: Using one statement to assemble them into one functor. I have tried: 1. boost::function< void() func( boost::bind( DataConsumer, & boost::bind( DataSource ) ) ); certainly it didn't work, compiler says it can not convert 'boost::_bi::bind_t ' to 'A *' 2. boost::function< void() func( boost::bind( DataConsumer, boost::addressof( boost::bind( DataSource ) ) )); compiler says cannot convert parameter 1 from 'boost::_bi::bind_t' to 'A &' Question: how to use return value from the nested boost::bind ? or if you want to use boost::lambda::bind.

• Getting a JPEG image from a hex string in XML.

  - by Jesse Knott

  Well here goes, I am trying to collect a picture that is encoded as a hex string in an xml file. I have been looking all over for the answer to this and have not been able to find it any where. Here is what I have now. byte[] bytes = Convert.FromBase64String(FilterResults("PHOTOGRAPH")); MemoryStream mem = new MemoryStream(bytes); Image bmp2 = Image.FromStream(mem); return bmp2; The FilterResults function just returns the string from the XML. I am able to get the string of characters and convert it into a byte[] but as soon as I execute the Image.FromStream(mem) I get an "Parameter Incorrect" error. Any ideas?

• Noob filter: How do I refer to a string that is passed to my Ruby on Rails method from Flex as a HTT

  - by ben

  I have a HTTPService in my Flex 4 app that I call like this: getUserDetails.send(userLookup.text); In my Ruby on Rails method that this is linked to, how do I refer to the userLookup.text parameter? The method is as follows, with XXX as the placeholder: def getDetails @user = User.first (:conditions => "username = XXX") render :xml => @user end UPDATE: Is this way correct? I found it here. I'm still getting errors but it might be because of something else. def getDetails(lookupUsername) @user = User.first (:conditions => "username = '#{lookupUsername}") render :xml => @user end Thanks for reading!

  - by Maik

  I am using a console app that starts several axis instances without using a packages archive. Like this: AxisService axisService2 = AxisService.createService( new Myclass.getClass().getName(), axisConfigurationContext.getAxisConfiguration()); axisService2.addParameter(new Parameter("useOriginalwsdl", "true")); axisConfigurationContext.getAxisConfiguration().addService(axisService2); Now, I need to serve a custom WSDL. I tried adding a META-INF folder to the bin-root, and in various other places, but with no success. How do I specify in this case the location of a custom WSDL? Thanks!

• how to send a dynamic set of parameters to webmethod using jquery ajax method?

  - by kranthi

  hi, I am using jquery ajax method on my aspx page,which will invoke the webmethod in the code behind.Currently the webmethod takes a couple of parameters like firstname,lastname,address etc which I am passing from jquery ajax method using data:JSON.stringify({fname:firstname,lname:lastname,city:city}) now my requirement has been changed such that,the number and type of parameters that are going to be passed is not fixed for ex.parameter combination can be something like fname,city or fname,city or city,lname or fname,lname,city or something else.So the webmethod should be such that it should accept any number parameters.I thought of using arrays to do so, as described here. But I do not understand how can I identify which and how many parameters have been passed to the webmethod to insert/update the data to the DB.Please could someone help me with this? thanks

• convert pointer to pointer to void pointer

  - by FihopZz

  When I'm learning to use qsort to sort an array of string, there is a question puzzled me. For example, to sort the following s char *s[] = { "Amit", "Garima", "Gaurav", "Vaibhav" }; To use the qsort, you must provide a comparison function like the following function cstring_cmp I guess in the qsort function, the type of parameter to be passed to the function cstring_cmp is char**. How to convert a char** to a void*? Why can we convert a char** to a void*? int cstring_cmp(const void *a, const void *b) { const char **ia = (const char **)a; const char **ib = (const char **)b; return -strcasecmp(*ia, *ib); /* return the negative of the normal comparison */ }

• Copy Structure To Another Program

  - by Steven

  Long story, long: I am adding a web interface (ASPX.NET: VB) to a data acquisition system developed with LabVIEW which outputs raw data files. These raw data files are the binary representation of a LabVIEW cluster (essentially a structure). LabVIEW provides functions to instantiate a class or structure or call a method defined in a .NET DLL file. I plan to create a DLL file containing a structure definition and a class with methods to transfer the structure. When the webpage requests data, it would call a LabVIEW executable with a filename parameter. The LabVIEW code would instantiate the structure, populate the structure from the data file, then call the method to transfer the data back to the website. Long story, short: How do you recommend I transfer (copy) an instance of a structure from one .NET program to a VB.NET program? Ideas considered: sockets, temp file, xml file, config file, web services, CSV, some type of serialization, shared memory

• how to write re-usable views in django?

  - by rz

  These are the techniques that I use regularly to make my views reusable: take the template_name as an argument with a default take an optional extra_context which defaults to empty {} right before the template is rendered the context is updated with the extra_context for further re-usability, call any callable in extra_context.values() whenever the view deals with a queryset, there is a queryset argument with a default whenever the view needs a particular object from the ORM, it attempts to fetch it using any "id" parameter in several ways (e.g. as a slug, as a database id) (this may be a bad practice...) First, Should I add anything to my list? Should I remove anything from my list? The items accommodates a large number of cases. However, whenever an app extends a model of another in some way (e.g. adding a field or changing the behavior in some way) I end up writing my own views and only reusing the model. Is this normal?

• Function returns CSV File: How to go about checking it ?

  - by Rachel

  I am doing something like: $outputFile = getCurrentDBSnapshot($data); where $data is the resource stream that am passing in, basically from command prompt am passing an file and am opening it using fopen for writing with 'w+' permissions, now getCurrentDBSnapshot would get the current state of a table and would update the $data csv file, so basically $outputFile would be updated with the current state of database table, now I want to var_dump or print the value of $outputFile to see the data present into it. But when I do $this->fout = fopen($outputFile,'r') or die('Cannot open file'); $test = fgetcsv($outputFile,5000,":"); var_dump($test); It gives me an error saying that it expects parameter 1 to be a string type and am passing resource. My goal to see the contains of $outputFile and so my question is that How can I see the contains present in $outputFile or how can I see what getcurrentDBSnapshot function is returning me ?

• Asp.Net MVC style routing in Django

  - by Andrew Hanson

  I've been programming in Asp.Net MVC for quite some time now and to expand a little bit beyond the .Net world I've recently began learning Python and Django. I am enjoying Django but one thing I am missing from Asp.Net MVC is the automatic routing from my urls to my controller actions. In Asp.Net MVC I can build much of my application using this single default route: routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); In Django I've found myself adding an entry to urls.py for each view that I want to expose which leads to a lot more url patterns than I've become used to in Asp.Net MVC. Is there a way to create a single url pattern in Django that will handle "[Application]/view/[params]" in a way similar to Asp.Net MVC? Perhaps at the main web site level?

• How to add animation on open of a Jquery SimpleModal?

  - by Obay

  The animation-enabled example in the SimpleModal site has this animation: 1. Fade in the overlay 2. Slide down the modal div This is the code: $("#the-div").modal({ onOpen: function (dialog) { dialog.overlay.fadeIn('fast', function () { dialog.data.hide(); dialog.container.show('fast', function () { dialog.data.slideDown('fast'); }); }); }}); I want this animation instead: 1. Just display the modal 2. Fade in the overlay Alas, simply removing the 2nd parameter of dialog.overlay.fadeIn() from the code above doesn't work. I also tried removing the parameters of dialog.container.show(), also changing it to dialog.container.open(). I've tried other combinations of the code, to no avail. How do I achieve the animation that I wish?

• Mobile Safari Geolocation API Issues

  - by sph

  Hi, since Mobile Safari's Geolocation API should be an implementation of the W3C Geolocation API I found some bugs. I was wondering if anybody noticed the same. As specified in the W3C Geolocation API the PositionCallback returns a Position object, which contains a Coordinates object. In this object all attributes are of type double. Using navigator.geolocation.getCurrentPosition and checking the Position object in the successCallback the accuracy attribute is always an object, but should be a double. The heading attribute is always -1 when testing in the iPhone simulator, but should be null or between 0 and 360. 2. Setting the options parameter for navigator.geolocation.watchPosition or navigator.geolocation.getCurrentPosition as specified in the W3C Geolocation API has no effect. No matter what is set as the timeout value, the win callback is called every 10 seconds. For example setting the timeout=1000 should immediately call either the successCallback or errorCallback. Thanks

• ff extension. how to pass parameters to a function in the oncommand attribute in menu

  - by encryptor

  I have a ff extension which creates a popup and shows dynamic data in it. basically when the popup opens a js function is run which then constructs the popup list by appending the items like this var myMenuPopup = document.getElementById("file-popup4"); newItem = document.createElement("menuitem"); newItem.setAttribute("label", namelist[m]); newItem.setAttribute("id", "item" + m); Now I need to have the click functionality too on these newly added menuitems. putting the atttribute and forming the function is easy. I can have a function to be run when they are clicked. But i need to pass namelist[i] to the function and it will act according to the namelist parameter.If i do: newItem.setAttribute("oncommand" , finalclick(namelist[m])); it runs the function everytime the popup opens runs the function without even clicking on it on the other hand if i use quotes i.i if i do newItem.setAttribute("oncommand" , "finalclick(namelist[m])"); it doesnot open even on clicking giving error : namelist is not defined.

• JQuery $.getJSON appends a question mark to the request URL

  - by David Neale

  I have the folliwng JSON request code on an ASP.NET MVC web application: var userID = 'id=' + $('#namesList').val(); $.getJSON('/Person/GetPerson/', userID, function(data) { $('#collar').text(data.collarNumber); $('#name').text(data.Name); $('#email').text(data.EmailAddress); }); This creates a request such as: http://localhost:48610/Person/GetPerson/?id=6. Why is there a question mark in there? I get the server error The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32'.... If I make the request manually without the question mark it works fine.

• How can I use a value from a session variable as part of the group name in signalR

  - by user1844734

  Hi I am trying to set up signalR to distribute messages to web users the problem is that the one site holds different 'areas' and also 'user types'. The Area is decided when the user visits the site by passing a url parameter, this is then stored in a session variable, The 'user type' is by default not logged in then changed when the user logs in to there user type (returned from a webservice) and stored in a User object. My aim was to connect to the hub using signalR when the user visits the site and add the users connectionId to a groupname, using the 'area id' from the session and the 'user type id' from the User object in the context. The problem I am having is that I can obtain the user id but when it comes to the area id signalR cannot access the session. I understand the reasoning behind not allowing the session available in signalR but does any one know if there is a way to enable this or an alternative way that I can gain access to the users area so that I can create these unique groups.

• How to set timeout with python-mechanize?

  - by Michal Cihar

  I'm using python-mechanize to scrape some web sites, which sometime simply don't respond to requests and these requests stay open too long, so I need to limit timeout for these requests. While using urlopen method, the timeout can be set using timeout parameter, but I have not found easy way for doing it with high level API such as submit or click methods. Ideally the timeout would be set just once for whole browser class and all calls would honor that. It would be probably possible to customize this by passing custom request_class to every click and submit call, but this would just pollute the code, so I'm looking for nicer solution for setting timeout for mechanize's browser class (and no, I don't want to change default socket timeout using socket.setdefaulttimeout).
