• using jquery (json) to get ajax database entries in wordpress - PHP not working

  - by Matt Facer

  I'm writing a plugin for my wordpress site and am having trouble understanding the jquery ajax requests. In a nutshell, I am trying to get some user meta data loaded when the page loads. So in my javascript file I have a line: $.getJSON("http://mysite.co.uk/wp-content/plugins/myplugin/ajax/ajax.php?action=test", function(json) { // do stuff }); So the above DOES get called, but it's the PHP code I'm having trouble with. In the file ajax.php, I am making a database call, but NONE of the usual class information is available. I've tried including the admin ajax page, various other pages from my own plugin (which does work).... not sure what else to do! The database call method works OK in my plugin code.. but I guess that the ajax.php file is outside the WP framework so that's why it's not working... but I don't know how to get it IN the framework!? I just need to use the $wpdb->get_results($sql); command to get my SQL. The error returned from firebug is that I am making a call to an undefined function. Thanks for any help... $.getJSON("http://www.offbeatattractions.co.uk/wp-content/plugins/wp-geo-extended/ajax/change_location.php?action=listpoints", function(json) { alert(json.Locations.length);

• Workflow UI Integration - is WF a good approach?

  - by AJ

  Somewhat similar to this question, except we haven't decided that we're going with WF yet. I'm working on designing a system that requires a series of decisions and activities on a "work object," so I naturally began to consider workflow, specifically WF. What I'm wondering is if WF is a good solution for a situation like the following (oversimplified for this question) case (please forgive bad ascii art): __________________ | Gather some info | | (web page) | |__________________| | | / \ / \ / \ / \ / cond \ \ 1 / \ / \ / \ / \ / | | ______________|_______________ | | | | | ______|______ ______|________ / do some / | Get more info | / process / | (web page) | /____________/ |_______________| | | / \ / \ / \ / cond. \ \ 2 / \ / \ / \ / | | |__________________ | | | | _____|_____ _____|_____ / some / / another / / process / / process / /__________/ /__________/ The part I'm struggling with is the get more info (web page) step and what happens subsequent, which would mean a halt in the execution of the workflow runtime. I'm aware that this is possible, but I'm not sure that WF is the best approach for this type of code, as the user interaction may be required at many different points through the entire workflow, and the workflow will drive what data entry screens are needed. We are using a WinForms/ASP.NET web forms package for UI, which is homegrown and difficult to push deployments on, so something like SharePoint integration is out of the question. Our back-end is DB2, and the workflow code (whether it's in WF or otherwise) will need to interact with that as well. I guess the bottom line is, should we look into using WF for this, or would we be better served just coding it ourselves? Can WF easily integrate data entry screens to capture information that can be used further on in the workflow?

• Error while installing Microsoft SharePoint 2010 on Windows 7 machine

  - by Brian Roisentul

  I've installed Microsoft SharePoint 2010 on my Windows 7 64bits machine. I've modified the config.xml file to accomplish this. Once it's installed I run the Configuration Wizard to create a new site and it throws me the following exception: An exception of type System.IO.FileNotFoundException was thrown.

• WPF Sizing of Panels

  - by Mystagogue

  I'm looking for an article or overview of WPF Panel types, that explains the sizing characters of each. For example, here are the panel types: http://msdn.microsoft.com/en-us/library/ms754152.aspx#Panels_derived_elements I've learned (by experiment) that UniformGrid can be given a fixed height, or it can be "auto" where it expands to fit available space. That is great, but what I wanted was for Uniform Grid to shrink to fit its internal content (particularly content that is provided dynamically, at run-time). I don't think it has that ability. So I'd like to know either what other Panel I could use for that purpose, or what Panel I should nest the UniformGrid inside of. But I don't just want an answer to that specific question. I want the sizing dynamics and capabilities of all the Panel types, in summary form, so I can make all these choices as needed. Online I find articles that cover only half the Panel types, and don't give as much information about sizing as I'm describing. Anyone know the link (or book) that has the info I'm seeking? p.s. Since I want the UniformGrid to shrink to the dynamic content I'm providing, I could just keep track of the total height of controls placed within, and then set the height of the UniformGrid. But it would be nice if WPF took care of this for me.

• How to assign .net membership roles to individual database records

  - by mdresser

  I'm developing a system where we want to restrict the availability of information displayed to users based on their roles. e.g. I have a tabled called EventType (ID, EventTypeDescription) which contains the following records: 1, 'Basic Event' 2, 'Intermediate Event' 3, 'Admin Event' What I need to achieve is to filter the records returned based on the username (and hence role) of the logged-in user. e.g if an advanced user is logged in they will see all the event types, if the standard user is logged in they will only see the basic event type etc. Ideally id like to do this in a way which can be easily extended to other tables as necessary. So I'd like to avoid simply adding a 'Roles' field to each table where the data is user context sensitive. One idea I'm thinking of is to create some kind of permissions table like: PermissionsTable ( ID, Aspnet_RoleId, TableName, PrimaryKeyValue ) this has the drawback of using this is obviously having to use the table name to switch which table to join onto. Edit: In the absence of any better suggestions, I'm going to go with the last idea I mentioned, but instead of having a TableName field, I'm going to normalise the TableName out to it's own table as follows: TableNames ( ID, TableName ) UserPermissionsTable ( ID, Aspnet_UserId, TableID, PrimaryKeyValue )

• XML Schema that describes a self-describing XML document

  - by Raegx

  Is it possible to write an XML Schema that describes an XML document that lists a set of elements and then requires other elements on that same XML document to use those values as either attributes and/or sub-elements? Example: define a list of locations, then force location attributes and/or location elements to be of those values. <root> <locations> <location>Home</location> <location>Office</location> <location>School</location> </locations> <addresses> <address location="Home">...</address> <address location="Office">...</address> </addresses> </root> or <root> <locations> <location>Home</location> <location>Office</location> <location>School</location> </locations> <addresses> <address> <location>Home</location> ... </address> <address> <location>Office</location> ... </address> </addresses> </root> I am failing hard at finding the proper way to search for this information. I suspect it is either not possible or I just don't know the right search terms.

• GAE - Getting TypeError requiring class instance be passed to class's own method...

  - by Spencer Leland

  I'm really new to programming... I set up a class to give supporting information for Google's User API user object. I store this info in the datastore using db.model. When I call the okstatus method of my user_info class using this code: elif user_info.okstatus(user): self.response.out.write("user allowed") I get this error: unbound method okstatus() must be called with user_info instance as first argument (got User instance instead) Here is my user_info class. class user_info: def auth_ctrlr(self, user): if self.status(user) == status_allowed: return ("<a href=\"%s\">Sign Out</a>)" % (users.create_login_url("/"))) else: return ("<a href=\"%s\">Sign In or Get an Account</a>)" % (users.create_logout_url("/"))) def status(self, user): match = sub_user.gql(qu_by_user_id, user.user_id) return match.string_status def group(self, user): match = sub_user.gql(qu_by_user_id, user.user_id) grp = group_names.gql(qu_by_user_id, match.groupID) return grp def okstatus(self, user): match = self.status(user) if match == status_allowed: return True My understanding is that the argument "self" inside the method's calling arguments describes it as a child to the class. I've tried everything I can think of and can't find any related info online. Can someone please tell me what I'm doing wrong? Thanks

• Connection details & timeouts in a java web service client

  - by f1sh

  Hello fellow Coders, I have to implement a webservice client to a given WSDL file. I used the SDK's 'wsimport' tool to create Java classes from the WSDL as well as a class that wrap's the webservice's only method (enhanceAddress(auth, param, address)) into a simple java method. So far, so good. The webservice is functional and returning results correcty. The code looks like this: try { EnhancedAddressList uniservResponse = getWebservicePort().enhanceAddress(m_auth, m_param, uniservAddress); //Where the Port^ is the HTTP Soap 1.2 Endpoint }catch (Throwable e) { throw new AddressValidationException("Error during uniserv webservice request.", e); } The Problem now: I need to get Information about the connection and any error that might occur in order to populate various JMX values (such as COUNT_READ_TIMEOUT, COUNT_CONNECT_TIMEOUT, ...) Unfortunately, the method does not officially throw any Exceptions, so in order to get details about a ConnectException, i need to use getCause() on the ClientTransportException that will be thrown. Even worse: I tried to test the read timeout value, but there is none. I changed the service's location in the wsdl file to post the request to a php script that simply waits forever and does not return. Guess what: The web service client does not time out but waits forever as well (I killed the app after 30+ minutes of waiting). That is not an option for my application as i eventually run out of tcp connections if some of them get 'stuck'. The enhanceAddress(auth, param, address) method is not implemented but annotated with javax.jws.* Annotations, meaning that i cannot see/change/inspect the code that is actually executed. Do i have any option but to throw the whole wsimport/javax.jsw-stuff away and implement my own soap client?

• Making HTTP POST request

• Detecting death of spawned process using Window CRT

  - by Michael Tiller

  Executive summary: I need a way to determine whether a Windows process I've spawned via _spawnl and am communicating with using FDs from _pipe has died. Details: I'm using the low-level CRT function in Windows (_eof, _read) to communicate with a process that was spawned via a call to _spawnl (with the P_NOWAIT) flag. I'm using _pipe to create file descriptors to communicate with this spawned process and passing those descriptors (the FD #) to it on the command line. It is worth mentioning that I don't control the spawned process. It's a black box to me. It turns out that the process we are spawning occasionally crashes. I'm trying to make my code robust to this by detecting the crash. Unfortunately, I can't see a way to do this. It seems reasonable to me to expect that a call to _eof or _read on one of those descriptors would return an error status (-1) if the process had died. Unfortunately, that isn't the case. It appears that the descriptors have a life of their own independent of the spawned process. So even though the process on the other end is dead, I get no error status on the file descriptor I'm using to communicate with it. I've got the PID for the nested process (returned from the _spanwnl call) but I don't see anything I can do with that. My code works really well except for one thing. I can't detect whether the spawned process is simply busy computing me an answer or has died. If I can use the information from _pipe and _spawnl to determine if the spawned process is dead, I'll be golden. Suggestions very welcome. Thanks in advance. UPDATE: I found a fairly simple solution and added it as the selected answer.

• Using $.get with jquery validation

  - by Jimmy McCarthy

  I'm trying to use the Jquery builtin validator on my page. The issue is that I have certain fields that only are required if the JobID (entered into another field) does not already exist in our database. I have a simple service which simply takes JobID and returns True or False based on whether the JobID exists, but I can't seem to get this information where I want it. Some sample code: $("#dep_form").validate({ rules: { JobID: { required: true, digits: true, minlength: 3 }, OrgName: { required: function(element) { //This field is required if the JobID is new. return $("#jobinfo").html().length==15; } } }, messages: { JobID: { required: "Enter a Job Number.", digits: "Only numbers are allowed in Job ID's.", minlength: "Job Number must be at least 3 digits" }, OrgName: { required: "Select a Practice from the dropdown list." } }, errorClass: "ui-state-error-input", errorLabelContainer: "#errorbox", errorElement: 'li', errorContainer: "#validation_errors", onfocusout: false, onkeyup: false, focusinvalid: false }; Currently, I'm using a lazy method to validate (shown above). However, I now have access to a service using the URL: var lookupurl = "/deposits/jobidvalidate/?q=" + $("#id_JobID").val() + "&t=" + new Date().getTime(); which is a page which will contain just the word True or False based on whether that given JobID exists. I've tried half a dozen different ways of setting variables and calling functions within functions and still cannot get a way to simply return the value of that page (which I've been trying to access with $.get() ) to my validator, so that required is set to true when the Job does not exist and false if the job already exists. Any suggestions? Thanks.

• jQuery RJS inserting string vs dom.

  - by Dmitriy Likhten

  So I am trying to use jQuery to insert data from an ajax call. I actually use the jquery.form plugin, and have the ajax form submitted with a dataType: 'script'. The response is a jquery expression which contains a <%= javascript_escape(render ...) %> erb tag (similar to what the railscasts episode 136 instructs to do). However the end result is that the full text of the render is inserted as if that was the content to be inserted into the page, as text, not as dom elements. Could the fact that the render had some newlines at the beginning be the cause? Dom text: "\n \n &lt;li>....&lt;/li>" I also tried having jQuery just read the response as a script and execute it, and used the prototype-based rjs stuff, same effect, the text is inserted into the dom. Are there any reasons why such a behavior would be experienced? A bit of clarification: My response.js.erb is jQuery("#content").append("<%= escape_javascript(render(:partial => "widgets")) %>"); jQuery("#information").text("Finally, something happened!"); The full text inside the append() call is inserted as text into #content.

• Facebook Connect - Using both FBML and PHP Client

  - by Ryan

  I am doing my second Facebook connect site. On my first site, I used the facebook coonect FBML to sign a user in, then I could access other information via the PHP Client. With this site, using the same exact code, it doesn't seem to be working. I'd like someone to be able to sign in using the Facebook button: <fb:login-button length="long" size="medium" onlogin="facebook_onlogin();"></fb:login-button> After they have logged in, the facebook_onlogin() function makes some AJAX requests to a PHP page which attempts to use the Facebook PHP Client. Here's the code from that page: $facebook = new Facebook('xxxxx API KEY xxxxx', 'xxxxx SECRET KEY xxxxx'); //$facebook->require_login(); ** I DONT WANT THIS LINE!! $userID = $facebook->api_client->users_getLoggedInUser(); if($userID) { $user_details = $facebook->api_client->users_getInfo($userID, 'last_name, first_name'); $firstName = $user_details[0]['first_name']; $lastName = $user_details[0]['last_name']; $this->view->userID = $userID; $this->view->firstName = $firstName; $this->view->lastName = $lastName; } The problem is that the PHP Client thinks I don't have a session key, so the $userID never get set. If I override the $userID with my facebook ID (which I am logged in with) I get this error: exception 'FacebookRestClientException' with message 'A session key is required for calling this method' in C:\wamp\www\mab\application\Facebook\facebookapi_php5_restlib.php:3003 If I uncomment the require_login(), it will get a session ID, but it redirects pages around a lot and breaks my AJAX calls. I am using the same code I successfully did this with on another site. Anyone have any ideas why the PHP client don't know about the session ID after a user has logged in with the connect button? Any ideas would be greatly appreciated. Thanks!

• Database design problem: intermediate table between 2 tables may end up with too many results.

  - by SK.

  I have to design a database to handle forms. Basically, a form needs to go through (exactly) 7 people, one by one. Each person can either agree or decline a form. If one declines, the chain stops and the following people don't even get notified that there is a form. Right now I have thought of those 3 tables: FORM, PERSON, and RESPONSE inbetween. However, my first solution sounds too heavy because each form could have up to 7 responses. Here we are with the table inbetween. That means that each successful form has 7 rows in the table RESPONSE. Here we have the responding information directly inside the form. It looks ugly but at least keeps everything as singular as possible. On the bad side I can't track the response dates, but I don't think it is crucial for that matter. What is your opinion on this? I feel like both of them are wrong and I don't know how to fix that. If that matters, I'll be using Oracle 9.

• Dynamically add User Controls to a Silverlight 4 page

  - by PilotBob

  I am building an iGoogle like "dashboard" for our application with silverlight 4. Each users dashboard (which snapins and their positions) will be stored in the database. Each snap in is a user control, for example... AwesomeSnapin.xaml. On the dashboard page in silverlight I am retrieving the users dashboard which is a collection of snapin objects which include the information on the snapin. I can store the name of the page or the class or whatever is needed. I have the following code which loops through the collection of snapins to add them to the dashboard page. In testing I have just hard coded a single snapin item. Here is the prototype code: foreach (var UserSnapin in op.Entities) { UserControl uc = new AmsiSL.eFinancials.BudgetCheck(); Canvas.SetLeft(uc, UserSnapin.PositionLeft); Canvas.SetTop(uc, UserSnapin.PositionTop); Layout.Children.Add(uc); MessageBox.Show(String.Format("Added {0}",UserSnapin.Snapin.Name)); } The above works fine... but of course adds the BudgetCheck snapin for every item that is defined for the users dashboard. Of course the messagebox is for debugging purposes only. How would I change line 3 of that to load the user control class (using classname or xaml path whichever is better) based on the data in the collection.

• Android SQLite database locale, locking, and version

  - by gdoten

  In some books and online I see these method calls being made after a database is created: db.setLocale(Locale.getDefault()); db.setLockingEnabled(true); db.setVersion(DB_VERSION); Why is this done? As far as I can tell, after creating a new database, the system adds a table named android_metadata with one field named locale and that table has one row with the locale field set to "en_US". Now I assume the column has that value because I am using a U.S. phone, and if I were using a phone from a different region then the locale field would be set appropriately. Can anyone confirm this? I'm guessing that the setLocale method would only be useful in the case that you install a pre-built database onto a phone and then want to change the locale to match the phone's locale. Sound right? The documentation for setLockingEnabled says it defaults to true so there's no need to make that call, right? Lastly, what's with the call to setVersion? I can't find a table that contains this information so I've been assuming that the database file itself stores the version number somewhere. So when I create a database, which requires you to have already specified the version number in the call to the SQLiteOpenHelper constructor, there's no point in calling setVersion. Again, perhaps this method exists for the case of installing a pre-built database to a device and you then wish to change the database's version (though I can't think of when doing this would make sense). Thanks for any insight!

• MVC: capture route url's and pass them to javascript function

  - by Tim Geerts

  Short:Is there a way to have a route-definition that will pass the "CONTROLLER/ACTION" string value to a javascript function in stead of actually going straight for the controller action? More:I have a masterpage which contains the navigation of the site. Now, all the pages need this navigation wrapped around it at all times, but because I didn't want the navigation to constantly load with each pagecall, I changed all my pages to partialviews. These partial views are loaded via the JQuery.Load() method whenever a menu item is clicked in the navigation. This all worked very good, up till now because I noticed it's also a requirement of the website to be able to link directly to page X, rather then default.aspx. So, as an example:The main page is my "default.aspx" page, this utilizes my master page with the nagivation around it. And each call to a new page uses a javascript function that loads that particular partial view inside a div that is known in my masterpage. So, the url never changes away from "default.aspx", but my content changes seemlesly. The problem is, those url's also need to be available when typed directly into the address bar. But, they're partial views, so loading them directly from the address bar makes them display without any masterpages around them. Therefore my question if it might be possible to capture the route typed into the address bar and pass that on to my javascript function that will load that route in the content div. (I hope I explained it ok enough, if not, feel free to ask more information)

• Disassembling with python - no easy solution?

  - by Abc4599

  Hi, I'm trying to create a python script that will disassemble a binary (a Windows exe to be precise) and analyze its code. I need the ability to take a certain buffer, and extract some sort of struct containing information about the instructions in it. I've worked with libdisasm in C before, and I found it's interface quite intuitive and comfortable. The problem is, its Python interface is available only through SWIG, and I can't get it to compile properly under Windows. At the availability aspect, diStorm provides a nice out-of-the-box interface, but it provides only the Mnemonic of each instruction, and not a binary struct with enumerations defining instruction type and what not. This is quite uncomfortable for my purpose, and will require a lot of what I see as spent time wrapping the interface to make it fit my needs. I've also looked at BeaEngine, which does in fact provide the output I need, a struct with binary info concerning each instruction, but its interface is really odd and counter-intuitive, and it crashes pretty much instantly when provided with wrong arguments. The CTypes sort of ultimate-death-to-your-python crashes. So, I'd be happy to hear about other solutions, which are a little less time consuming than messing around with djgcc or mingw to make SWIGed libdisasm, or writing an OOP wrapper for diStorm. If anyone has some guidance as to how to compile SWIGed libdisasm, or better yet, a compiled binary (pyd or dll+py), I'd love to hear/have it. :) Thanks ahead.

• cocoa - making a class like UIButton

  - by Mike

  For some reason that will take too much time to explain, I have to create a UIImageView based class that has some properties of a button. Imagine a class like the UISwitch (no I cannot base my class on the UISwitch) with two states, on and off. WHen the user selects one state, it runs a method like a button that was clicked and the method receives the sender id. I have already the class more or less working. The class is based on UIImageView. I am having difficulties to understand the following. WHen I create a new button I have a line that is like [myButton addTarget:self action:NSSelectorFromString(myMethod) forControlEvents:UIControlEventTouchUpInside]; This line defines a target and an action to run when the button is triggered. I my case I would need something like [myObject addTarget:self action:myMethod ifState:1] //or another thing ifState:2 I have no idea what kind of code I should put on the class to make this work. Remember that as a button the class should send the "sender" information to identify the object which triggered the action... Can you guys, transcendental gurus help? thanks.

• Comparing RPG to C# and SQL.

  - by Kevin

  In an RPG program (One of IBM's languages on the AS/400) I can "chain" out to a file to see if a record (say, a certain customer record) exists in the file. If it does, then I can update that record instantly with new data. If the record doesn't exist, I can write a new record. The code would look like this: Customer Chain CustFile 71 ;turn on indicator 71 if not found if *in71 ;if 71 is "on" eval CustID = Customer; eval CustCredit = 10000; write CustRecord else ;71 not on, record found. CustCredit = 10000; update CustRecord endif Not being real familiar with SQL/C#, I'm wondering if there is a way to do a random retrieval from a file (which is what "chain" does in RPG). Basically I want to see if a record exists. If it does, update the record with some new information. If it does not, then I want to write a new record. I'm sure it's possible, but not quite sure how to go about doing it. Any advice would be greatly appreciated.

• Query by datetime in JDOQL / Java / GAE

  - by Jan Kuboschek

  I'm working on a GAE app. I want to query datastore and retrieve all records between startDate and endDate. Each record has a datetime field. I'm using a query similar to this (the below code is something I quickly grabbed - I'm not near my developer machine.): Query query = pm.newQuery(Employee.class); query.setFilter("lastName == lastNameParam"); query.setOrdering("hireDate desc"); query.declareParameters("String lastNameParam"); try { List results = (List) query.execute("Smith"); if (results.iterator().hasNext()) { for (Employee e : results) { // ... } } else { // ... no results ... } } finally { query.closeAll(); } How do I have to format the date to form a correctly working query? How is the datetime stamp stored in datastore? As timestamp? Fully formatted? I can't find ANY information on this. Please help.

• Parsing tnsnames.ora using regex...

  - by Welton v3.50

  I am attempting to pull some information from my tnsnames file using regex. I started with the following pattern: MYSCHEMA *? = *?[\W\w\S\s]*\(HOST *?= *?(?<host>\w+\s?)\)\s?\(PORT *?= *?(?<port>\d+)\s?\)[\W\w\S\s]*\(SERVICE_NAME *?= *?(?<servicename>\w+)\s?\) which worked fine when MYSCHEMA was the only schema in the file, but when there are other schemas listed after MYSCHEMA it matches all the way to the last schema. I have since created a new pattern: MYSCHEMA *=\s*\(DESCRIPTION =\s*\(ADDRESS *= *\(PROTOCOL *= *TCP\)\(HOST *= *(?<host>\w+)\)\(PORT *= *(?<port>\d+)\)\)\s*\(CONNECT_DATA *=\s*(?<serverdedicated>\(SERVER *= *DEDICATED\))\s*\(SERVICE_NAME *= *(?<servicename>[\w\.]+) *\)\s*\)\s*\) This pattern matches MYSCHEMA only, but I had to add every element that appeared in MYSCHEMA entry, and it won't match MYOTHERSCHEMA if it does not contain all the same elements. Ideally, I'd like a pattern that matches MYSCHEMA entry only, and captures HOST, PORT and SERVICE NAME, and optionally (SERVER = DEDICATED) (which I didn't have in the first pattern) to named groups. Below is the sample tnsnames that I've been using for testing: SOMESCHEMA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = REMOTEHOST)(PORT = 1234)) ) (CONNECT_DATA = (SERVICE_NAME = REMOTE) ) ) MYSCHEMA = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = MYHOST)(PORT = 1234)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = MYSERVICE.LOCAL ) ) ) MYOTHERSCHEMA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = MYHOST)(PORT = 1234)) ) (CONNECT_DATA = (SERVICE_NAME = MYSERVICE.REMOTE) ) ) SOMEOTHERSCHEMA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = LOCALHOST)(PORT = 1234)) ) (CONNECT_DATA = (SERVICE_NAME = LOCAL) ) )

• Operator issues with cout

  - by BSchlinker

  I have a simple package class which is overloaded so I can output package data simply with cout << packagename. I also have two data types, name which is a string and shipping cost with a double. protected: string name; string address; double weight; double shippingcost; ostream &operator<<( ostream &output, const Package &package ) { output << "Package Information ---------------"; output << "Recipient: " << package.name << endl; output << "Shipping Cost (including any applicable fees): " << package.shippingcost; The problem is occurring with the 4th line (output << "Recipient:...). I'm receiving the error "no operator "<<" matches these operands". However, line 5 is fine. I'm guessing this has to do with the data type being a string for the package name. Any ideas?
