  • function not working R

    - by user3722828
    I've never programmed before and am trying to learn. I'm following that "coursera" course that I've seen other people post about — a course offered by Johns Hopkins on R programming. Anyway, this was supposed to be my first function. Yet, it doesn't work! But when I type out all the steps individually, it runs just fine... Can anyone tell me why? > pollutantmean <- function(directory, pollutant, id = 1:332){ + x<- list.files("/Users/mike******/Desktop/directory", full.names=TRUE) + y<- lapply(x, read.csv) + z<- do.call(rbind.data.frame, y[id]) + + mean(z$pollutant, na.rm=TRUE) + } > pollutantmean(specdata,nitrate,1:10) [1] NA Warning message: In mean.default(z$pollutant, na.rm = TRUE) : argument is not numeric or logical: returning NA #### > x<- list.files("/Users/mike******/Desktop/specdata",full.names=TRUE) > y<- lapply(x,read.csv) > z<- do.call(rbind.data.frame,y[1:10]) > mean(z$nitrate,na.rm=TRUE) [1] 0.7976266

  • Html Select List: why would onchange be called twice?

    - by Mark Redman
    I have a page with a select list (ASP.NET MVC Page) The select list and onchange event specified like this: <%=Html.DropDownList("CompanyID", Model.CompanySelectList, "(select company)", new { @class = "data-entry-field", @onchange = "companySelectListChanged()" })%> The companySelectListChanged function is getting called twice? I am using the nifty code in this question to get the caller. both times the caller is the onchange event, however if i look at the callers caller using: arguments.callee.caller.caller the first call returns some system code as the caller (i presume) and the second call returns undefined. I am checking for undefined to only react once to onchange, but this doesnt seem ideal, whcy would onchange be called twice? UPDATE: ok, found the culprit! ...apart from me :-) but the issue of calling the companySelectListChanged function twice still stands. The onchange event is set directly on the select as mentioned. This calls the companySelectListChanged function. ..notice the 'data-entry-field' class, now in a separate linked javascript file a change event on all fields with this class is bound to a function that changes the colour of the save button. This means there is two events on the onchange, but the companySelectListChanged is called twice? The additional binding is set as follows: $('.data-entry-field').bind('keypress keyup change', function (e) { highLightSaveButtons(); }); Assuming its possible to have 2 change events on the select list, its would assume that setting keypress & keyup events may be breaking something? Any ideas?

  • Hitting a ADO.NET Data Services from WPF client, forms authentication

    - by Soulhuntre
    Hey all! There are a number of questiosn on StackOverflow that ALMOST hit this topic head on, but they are either for other technologies, reference obsolets information or don;t supply an answer that I can suss out. So pardon the almost duplication :) I have a working ADO.NET Data Service, and a WPF client that hits it. Now that they are working fine I want to add authentication / security to the system. My understanding of the steps so far is... Turn on forms authentication and configure it on the server (I have an existing asp.net membership service DB for other aspects of this app, so that isnt a problem) so that it is required for the service URL In WCF apply for and recieve a forms authentication "ticket" as part of a login routine Add that "ticket" to the headers of the ADO.NET service calls in WPF Profit! All well and good - but does anyone have a line on a soup to nuts code sample, using the modern releases of these technologies? Thanks!

  • Conversion constructor vs. conversion operator: precedence

    - by GRB
    Reading some questions here on SO about conversion operators and constructors got me thinking about the interaction between them, namely when there is an 'ambiguous' call. Consider the following code: class A; class B { public: B(){} B(const A&) //conversion constructor { cout << "called B's conversion constructor" << endl; } }; class A { public: operator B() //conversion operator { cout << "called A's conversion operator" << endl; return B(); } }; int main() { B b = A(); //what should be called here? apparently, A::operator B() return 0; } The above code displays "called A's conversion operator", meaning that the conversion operator is called as opposed to the constructor. If you remove/comment out the operator B() code from A, the compiler will happily switch over to using the constructor instead (with no other changes to the code). My questions are: Since the compiler doesn't consider B b = A(); to be an ambiguous call, there must be some type of precedence at work here. Where exactly is this precedence established? (a reference/quote from the C++ standard would be appreciated) From an object-oriented philosophical standpoint, is this the way the code should behave? Who knows more about how an A object should become a B object, A or B? According to C++, the answer is A -- is there anything in object-oriented practice that suggests this should be the case? To me personally, it would make sense either way, so I'm interested to know how the choice was made. Thanks in advance

  • Why does Graphviz fail on gvLayout?

    - by David Brown
    Once again, here I am writing C without really knowing what I'm doing... I've slapped together a simple function that I can call from a C# program that takes a DOT string, an output format, and a file name and renders a graph using Graphviz. #include "types.h" #include "graph.h" #include "gvc.h" #define FUNC_EXPORT __declspec(dllexport) // Return codes #define GVUTIL_SUCCESS 0 #define GVUTIL_ERROR_GVC 1 #define GVUTIL_ERROR_DOT 2 #define GVUTIL_ERROR_LAYOUT 3 #define GVUTIL_ERROR_RENDER 4 FUNC_EXPORT int RenderDot(char * dotData, const char * format, const char * fileName) { Agraph_t * g; // The graph GVC_t * gvc; // The Graphviz context int result; // Result of layout and render operations // Create a new graphviz context gvc = gvContext(); if (!gvc) return GVUTIL_ERROR_GVC; // Read the DOT data into the graph g = agmemread(dotData); if (!g) return GVUTIL_ERROR_DOT; // Layout the graph result = gvLayout(gvc, g, "dot"); if (result) return GVUTIL_ERROR_LAYOUT; // Render the graph result = gvRenderFilename(gvc, g, format, fileName); if (result) return GVUTIL_ERROR_RENDER; // Free the layout gvFreeLayout(gvc, g); // Close the graph agclose(g); // Free the graphviz context gvFreeContext(gvc); return GVUTIL_SUCCESS; } It compiles fine, but when I call it, I get GVUTIL_ERROR_LAYOUT. At first, I thought it might have been how I was declaring my P/Invoke signature, so I tested it from a C program instead, but it still failed in the same way. RenderDot("digraph graphname { a -> b -> c; }", "png", "C:\testgraph.png"); Did I miss something? EDIT If there's a chance it has to do with how I'm compiling the code, here's the command I'm using: cl gvutil.c /I "C:\Program Files (x86)\Graphviz2.26\include\graphviz" /LD /link /LIBPATH:"C:\Program Files (x86)\Graphviz2.26\lib\release" gvc.lib graph.lib cdt.lib pathplan.lib I've been following this tutorial that explains how to use Graphviz as a library, so I linked to the .lib files that it listed.

  • Slimbox 2 Plugin, jQuery Flickr, and IE8

    - by Nick H.
    Hello, I am currently developing a site that I make use of two jQuery plugins: Flickr jquery plugin (http://code.google.com/p/jquery-flickr/) Slimbox (http://code.google.com/p/slimbox/) The first plugin is used to pull in flickr photos from a specific account. These photos are displayed as thumbnails on the page. I am then using the second plugin to display larger views of these images. Because the flickr photos are fetched when the page loads, I am calling the Slimbox 2 function like this: $(document).ready(function() { $("#Flickr").flickr(); //Call Flickr plugin $(window).bind('load', function() { $("#Flickr a").slimbox();//Call Slimbox2 }); }); On first testing this seemed to have worked perfectly. I tested multiple versions of FireFox, IE7, IE6, and Safari. Everything is great. However, the Slimbox lightbox effest does not work in IE8. However, if I put IE8 into compatibility mode, everything works as expected. I would like to avoid forcing compatibility mode. There are no javascript errors and I am at a loss for testing. Here is a link to a sample: http://www.njhall.com/JRMcCourt-Builders/index.html#ourwork Any advice would be greatly appreciated. Thanks Nick

    I'm using suds for the first time and trying to communicate with a server hosted by an external company.

  • How can I use external expressions in Linq with EF4 (and LINQKit)?

    - by neo
    I want to separate out often used expressions in linq queries. I'm using Entity Framework 4 and also LINQKit but I still don't know how I should do it the right way. Let me give you an example: Article article = dataContainer.Articles.FirstOrDefault(a => a.Id == id); IEnumerable<Comment> comments = (from c in container.Comments where CommentExpressions.IsApproved.Invoke(c) select c); public static class CommentExpressions { public static Expression<Func<Module, bool>> IsApproved { get { return m => m.IsApproved; } } } Of course the IsApproved expression would be something much more complicated. The problem is that the Invoke() won't work because I didn't call .asExpandable() from LINQKit on container.Comments but I can't call it because it's just an ICollection instead of an ObjectSet. So my question is: Do I always have to go through the data context when I want to include external expressions or can I somehow use it on the object I fetched (Article)? Any ideas or best practices? Thanks very much! neo

  • Explicit casting doesn't work in default model binding

    - by Felix
    I am using ASP.NET MVC2 and Entity Framework. I am going to simplify the situation a little; hopefully it will make it clearer, not more confusing! I have a controller action to create address, and the country is a lookup table (in other words, there is a one-to-many relationship between Country and Address classes). Let's say for clarity that the field in the Address class is called Address.Land. And, for the purposes of the dropdown list, I am getting Country.CountryID and Country.Name. I am aware of Model vs. Input validation. So, if I call the dropdown field formLand - I can make it work. But if I call the field Land (that is, matching the variable in Address class) - I am getting the following error: "The parameter conversion from type 'System.String' to type 'App.Country' failed because no type converter can convert between these types." OK, this makes sense. A string (CountryID) comes from the form and the binder doesn't know how to convert it to Country type. So, I wrote the converter: namespace App { public partial class Country { public static explicit operator Country(string countryID) { AppEntities context = new AppEntities(); Country country = (Country) context.GetObjectByKey( new EntityKey("AppEntities.Countries", "CountryID", countryID)); return country; } } } FWIW, I tried both explicit and implicit. I tested it from the controller - Country c = (Country)"fr" - and it works fine. However, it never got invoked when the View is posted. I am getting the same "no type converter" error in the model. Any ideas how to hint to the model binder that there is a type converter? Thanks

  • ASP Classic page quit working

    - by justSteve
    I've had a set of legacy pages running on my IIS7 server for at least a year. Sometime last week something changed and now this line: Response.Write CStr(myRS(0).name) & "=" & Cstr(myRS(0).value) which used to return nothing more exciting than the string: 'Updated=true' (the sproc processing input params, stores them to a table, checks for errors and when that's all done returns a success code by executing this statement: select 'true' as [Updated] Now my pageside error handler is being involved and offers: myError=Error from /logQuizScore.asp Error source: Microsoft VBScript runtime error Error number: 13 Error description: Type mismatch Important to note that all lots of pages use the same framework - same db, same coding format, connecitonstrings and (so far as I can tell) all others are working. Troubleshot to this point: The call to the stored procedure is working correctly (stuff is stored to the given table). The output from the stored procedure is working correctly (i can execute a direct call with the given parameters and stuff works. I can see profiler calling and passing. I can replace all code with 'select 'true' as updated' and the error is the same. everything up to the response.write statement above is correct. So something changed how ADO renders that particular recordset. So i try: Response.Write myRS.Item.count and get: Error number: 424 Error description: Object required The recordset object seems not to be instantiating but the command object _did execute.

  • How do you handle 'SelectedItemChanged' events in a MVVM ViewModel?

    - by Travis
    I have some logic that depends upon two properties being set, as it executes when both properties have a value. For example: private void DoCalc() { if (string.IsNullOrEmpty(Property1) || string.IsNullOrEmpty(Property2)) return; Property3 = Property1 + " " + Property2; } That code would need to be executed every time Property1 or Property2 changed, but I'm having trouble figuring out how to do it in a stylistically acceptable manner. Here are the choices as I see them: 1) Call method from ViewModel I don't have a problem with this conceptually, as the logic is still in the ViewModel - I'm not a 'No code-behind' nazi. However, the 'trigger' logic (when either property changes) is still in the UI layer, which I don't love. The codebehind would look like this: void ComboBox_Property1_SelectedItemChanged(object sender, RoutedEventArgs e) { viewModel.DoCalc(); } 2) Call method from Property Setter This approach seems the most 'pure', but it also seems ugly, as if the logic is hidden. It would look like this: public string Property1 { get {return property1;} set { if (property1 != value) { property1 = value; NotifyPropertyChanged("Property1"); DoCalc(); } } } 3) Hook into the PropertyChanged event I'm now thinking this might be the right approach, but it feels weird to hook into the property changed event in the implementing viewmodel. It would look something like this: public ViewModel() { this.PropertyChanged += new PropertyChangedEventHandler(ViewModel_PropertyChanged); } void ViewModel_PropertyChanged(object sender, PropertyChangedEventArgs e) { if (e.PropertyName == "Property1" || e.PropertyName == "Property2") { DoCalc(); } } So, my question is, if you were browsing through some source code with that requirement, which approach would you prefer to see implemented (and why?). Thanks for any input.

  • MVC.NET project won't start under IIS 5.1 on Windows XP SP3

    - by mrjoltcola
    I've a MVC.NET 2 project that runs fine under Windows 7 and will start on Windows XP if I use the Visual Studio Development Server, however, starting under IIS generates an error: Unable to start debugging on the web server With the message The specified procedure could not be found No errors in the system event viewer. If I start without debugging I get an "HTTP 500 Internal Server Error" The reason I run it under IIS is the project also includes some WCF wsHttp web services that use certificates, so the VS Development Server is not adequate for hosting those. I have already seen the links on SO that talk about adding the wildcard mapping. I've already done that, just as I've done on Windows Server 2003 where I successfully host MVC.NET RC2 for quite a while.

  • Unresolved Host Exception Android

    - by Rob Stevenson-Leggett
    I'm trying to call a RESTful web service from an Android application using the following method: HttpHost target = new HttpHost("http://" + ServiceWrapper.SERVER_HOST,ServiceWrapper.SERVER_PORT); HttpGet get = new HttpGet("/list"); String result=null; HttpEntity entity = null; HttpClient client = new DefaultHttpClient(); try { HttpResponse response=client.execute(target, get); entity = response.getEntity(); result = EntityUtils.toString(entity); } catch (Exception e) { e.printStackTrace(); } finally { if (entity!=null) try { entity.consumeContent(); } catch (IOException e) {} } return result; I can browse to address and see the xml results using the Android Emulator browser and from my machine. I have given my app the INTERNET permission. I'm developing with eclipse. I've seen it mentioned that I might need to configure a proxy but since the web service i'm calling is on port 80 this shouldn't matter should it? I can call the method with the browser. Any ideas?

  • C# Social Networking SDK

    - by Nix
    I am currently gathering some technology requirements for a site that will be a social network based. I don't want to re-invent the wheel so i am looking for some type of SDK or collection of tools that can provide me with a way of creating/managing a social network. I understand that no framework will probably fit my exact needs so I am also looking for a flexible/extendable framework. An example extension point would be allowing the user to provide sub networks, maybe a global network that could be sub classified as work and friends. Beyond that it would also be nice to somehow be able to import contacts from other networking sites (Facebook, Linked In, etc). My current technology suite will consist of the following: IIS 7.0 WCF Data Services SQL Server 2006 ASP.NET front end. If there is any more information you may need please let me know.

    hi guys, i'm new to the asp.net mvc. and i have a link which will popup show a 3 panes listbox which allows the user to select country, region and language. and when the user click on the language, this will redirect back to the controller and refresh the page and show the proper localized content. i was thinking of using a jquery dialog/modal to do this but so i try using fancybox for this which will load the hidden div of the three listbox up. unfortunately, on clicking on the first listbox, the page will call a jquery event which will show the populate the 2nd list box in which the lightbox will close. is there a better way to do this? or i'm not using the proper jquery plugin? i was thinking of putting the whole three panes inside a html file and do ajax call to get the content into that page and load the listbox like that and just use the html popup like a normal popup. Any suggestions? i'm stuck, help!!

  • Ajax actionlinks straight from a DropDownList

    - by Ingó Vals
    I've got a small linkbox on the side of my page that is rendered as a PartialView. In it I have a dropDownlist the should change the routing value of the links in the box but I'm having difficulty doing so. My current plan is to call on something similar to a Ajax.ActionLink to reload the partial view into the with a different parameter based on the value of the dropdown selection. However I'm having multiple problems with this, for example as a novice in using dropdownlists I have no idea how to call on the selected value for example. <%= Html.DropDownList("DropDownList1", new SelectList(Model, "ID", "Name"), "--Pick--", new { AutoPostBack = "true", onchange = "maybe something here" })%> I tried putting in the sys.mvc.AsyncHyperlink into the onchange attribute and that worked except I don't know how to put in the route value for it. Sys.Mvc.AsyncHyperlink.handleClick(this, new Sys.UI.DomEvent(event), { insertionMode: Sys.Mvc.InsertionMode.replace, updateTargetId: 'SmallMenu' } Is there no straight Ajax drop down list that fires events onchange? Any way this is possible? I have later in the Partial view the Ajax actionlinks but they need to have their id's updated by the value in the dropdownlist and if I could do that somehow else I would appreciate a suggestion.

  • ASP.NET MVC Session Expiration

    - by Andrew Flanagan
    We have an internal ASP.NET MVC application that requires a logon. Log on works great and does what's expected. We have a session expiration of 15 minutes. After sitting on a single page for that period of time, the user has lost the session. If they attempt to refresh the current page or browse to another, they will get a log on page. We keep their request stored so once they've logged in they can continue on to the page that they've requested. This works great. However, my issue is that on some pages there are AJAX calls. For example, they may fill out part of a form, wander off and let their session expire. When they come back, the screen is still displayed. If they simply fill in a box (which will make an AJAX call) the AJAX call will return the Logon page (inside of whatever div the AJAX should have simply returned the actual results). This looks horrible. I think that the solution is to make the page itself expire (so that when a session is terminated, they automatically are returned to the logon screen without any action by them). However, I'm wondering if there are opinions/ideas on how best to implement this specifically in regards to best practices in ASP.NET MVC.

  • jQuery AJAX slow in Firefox, fast in IE

    - by Brandon Montgomery
    I'm using jQuery to post to an ASP .NET Web Service to implement a custom auto-complete function. The code works great, except it's slow in FireFox (can't get it to go faster than 1 second). IE is blazing fast - works great. I watch the post in Firefox using Firebug. Here's the service code: <ScriptService(), _ WebService(Namespace:="http://tempuri.org/"), _ WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1), _ ToolboxItem(False)> _ Public Class TestWebSvc Inherits System.Web.Services.WebService <WebMethod(), _ ScriptMethod(ResponseFormat:=Script.Services.ResponseFormat.Json, UseHttpGet:=True)> _ Public Function GetAccounts(ByVal q As String) As Object 'Code taken out for simplicity Return result End Function End Class And the jQuery ajax call: $.ajax({ beforeSend: function (req) { req.setRequestHeader("Content-Type", "application/json"); }, contentType: "application/json; charset=utf-8", type: "GET", url: "http://localhost/Suggest/TestWebSvc.asmx/GetAccounts", data: "q='" + element.val() + "'", dataType: "json", success: testWebSvcSuccess }); As you can see, I've tried to use the HTTP GET verb instead in hopes that that would make the call faster. As it does not, I'll probably switch it back to using POST if I can. Right now I'm just focused on why it's super fast in IE and super slow in Firefox. Versions: jQuery 1.3.2; Firefox 3.0.11; IE 8.0.6001.18783 (64-bit) Thank you for any insight you can provide.

  • Cannot rollback ransaction with Entity Framework

    - by Luca
    I have to do queries on uncommitted changes and I tried to use transactions, but I found that it do not work if there are exceptions. I made a simple example to reproduce the problem. I have a database with only one table called "Tabella" and the table has two fields: "ID" is a autogenerated integer, and "Valore" is an integer with a Unique constraint. Then I try to run this code: using (TransactionScope scope = new TransactionScope()) { Db1Container db1 = new Db1Container(); try { db1.AddToTabella(new Tabella() { Valore = 1 }); db1.SaveChanges(); } catch { } try { db1.AddToTabella(new Tabella() { Valore = 1 }); db1.SaveChanges(); //Unique constraint is violated here and an exception is thrown } catch { } try { db1.AddToTabella(new Tabella() { Valore = 2 }); db1.SaveChanges(); } catch { } //scope.Complete(); //NEVER called } //here everything should be rolled back Now if I look into the database it should contain no records because the transaction should rollback, instead I find two records!!!! One with Valore=1 and one with Valore=2. I am missing something? It looks like the second call to SaveChanges method rollback its own changes and "deletes" the transaction, then the third call to SaveChanges commits the changes of the first and the third insert (at this point it is like the transaction not exists). I also tried to use SaveChanges(false) method (even without calling AcceptAllChanges method), but with no success: I have the same behaviour. I do not want the transaction to be rolled back automatically by SaveChanges, because I want to correct the errors (for example by user interaction in the catch statement) and make a retry. Can someone help me with this? It seems like a "bug", and it is giving me a really big headache...

  • How do I interact with OData from Java?

    - by user280638
    OData is Microsoft's repackaging of its Astoria (now WCF Data Services) RESTful query/update protocol. If I want to use Java to create an OData compatible data source, how do I do that? Similarly, if I want to consume an OData data source from Java, how do I do that? http://www.odata.org/ Partial answer below. The OData website suggests that Restlet supports OData. Restlet's API documentation mentions the org.restlet.ext.odata package. www.restlet.org/ www.restlet.org/documentation/snapshot/jee/ext/org/restlet/ext/odata/package-summary.html Is this the only answer? Are there blog posts on doing this integration?

  • Connecting to a Ghost User in Flex RTMFP

    - by Dan
    I have a simple Flex RTMFP P2P video app in the same mold as the Adobe Cirrus VideoPhone Sample application. A problem I've been encountering in developing this app (the same problem occurs in the sample) is when you try to connect to a ghost Stratus instance i.e you try to call someone whose Stratus id is in the database but who is no longer on the page. So here's an example of what I mean: Let's say you go to the Adobe Stratus sample and connect as Dan. Then open up a new tab, go to the sample again and connect as Fred. If from this point, you (as Fred) call Dan everything will work fine. But, if you close the tab in which you connected as Dan, and then from the Fred tab try to connect to Dan the program will just hang. I would have thought there would be a NetStream event that would be triggered if you tried to connect to a Stratus instance that is not longer online but I can't seem to find anything besides NetStream.Connect.Rejected which doesn't seem to be called. Any help is much appreciated!

  • Obj-C component-based game architecture and message forwarding

    - by WanderWeird
    Hello, I've been trying to implement a simple component-based game object architecture using Objective-C, much along the lines of the article 'Evolve Your Hierarchy' by Mick West. To this end, I've successfully used a some ideas as outlined in the article 'Objective-C Message Forwarding' by Mike Ash, that is to say using the -(id)forwardingTargetForSelector: method. The basic setup is I have a container GameObject class, that contains three instances of component classes as instance variables: GCPositioning, GCRigidBody, and GCRendering. The -(id)forwardingTargetForSelector: method returns whichever component will respond to the relevant selector, determined using the -(BOOL)respondsToSelector: method. All this, in a way, works like a charm: I can call a method on the GameObject instance of which the implementation is found in one of the components, and it works. Of course, the problem is that the compiler gives 'may not respond to ...' warnings for each call. Now, my question is, how do I avoid this? And specifically regarding the fact that the point is that each instance of GameObject will have a different set of components? Maybe a way to register methods with the container objects, on a object per object basis? Such as, can I create some kind of -(void)registerMethodWithGameObject: method, and how would I do that? Now, it may or may not be obvious that I'm fairly new to Cocoa and Objective-C, and just horsing around, basically, and this whole thing may be very alien here. Of course, though I would very much like to know of a solution to my specific issue, anyone who would care to explain a more elegant way of doing this would additionally be very welcome. Much appreciated, -Bastiaan
