  • Error when passing data between views

    - by Kristoffer Bilek
    I'm using a plist (array of dictionaries) to populate a tableview. Now, when a cell i pressed, I want to pass the reprecented dictionary to the detail view with a segue. It's working properly to fill the tableview, but how do I send the same value to the detail view? This is my try: #import "WinesViewController.h" #import "WineObject.h" #import "WineCell.h" #import "WinesDetailViewController.h" @interface WinesViewController () @end @implementation WinesViewController - (id)initWithStyle:(UITableViewStyle)style { self = [super initWithStyle:style]; if (self) { // Custom initialization } return self; } - (void)viewDidLoad { [super viewDidLoad]; } - (void)viewDidUnload { [super viewDidUnload]; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationPortrait); } #pragma mark - Table view data source - (void)viewWillAppear:(BOOL)animated { wine = [[WineObject alloc] initWithLibraryName:@"Wine"]; self.title = @"Vinene"; [self.tableView deselectRowAtIndexPath:[self.tableView indexPathForSelectedRow] animated:YES]; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { // Return the number of sections. return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { // Return the number of rows in the section. return [wine libraryCount]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"wineCell"; WineCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; // Configure the cell... cell.nameLabel.text = [[wine libraryItemAtIndex:indexPath.row] valueForKey:@"Name"]; cell.districtLabel.text = [[wine libraryItemAtIndex:indexPath.row] valueForKey:@"District"]; cell.countryLabel.text = [[wine libraryItemAtIndex:indexPath.row] valueForKey:@"Country"]; cell.bottleImageView.image = [UIImage imageNamed:[[wine libraryItemAtIndex:indexPath.row] valueForKey:@"Image"]]; cell.flagImageView.image = [UIImage imageNamed:[[wine libraryItemAtIndex:indexPath.row] valueForKey:@"Flag"]]; cell.fyldeImageView.image = [UIImage imageNamed:[[wine libraryItemAtIndex:indexPath.row] valueForKey:@"Fylde"]]; cell.friskhetImageView.image = [UIImage imageNamed:[[wine libraryItemAtIndex:indexPath.row] valueForKey:@"Friskhet"]]; cell.garvesyreImageView.image = [UIImage imageNamed:[[wine libraryItemAtIndex:indexPath.row] valueForKey:@"Garvesyre"]]; return cell; } #pragma mark - Table view delegate - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { if ([[segue identifier] isEqualToString:@"DetailSegue"]) { NSIndexPath *selectedRowIndex = [self.tableView indexPathForSelectedRow]; WinesDetailViewController *winesdetailViewController = [segue destinationViewController]; //Here comes the error line: winesdetailViewController.winedetailName = [wine objectAtIndex:indexPath.row] valueForKey:@"Name"]; } } I get one error for: winesdetailViewController.winedetailName = [wine objectAtIndex:indexPath.row] valueForKey:@"Name"]; Use of undeclaired identifier: indexPath. did you mean NSIndexPath? I think I've missed something important here..

  • Validating parameters according to a fixed reference

    - by James P.
    The following method is for setting the transfer type of an FTP connection. Basically, I'd like to validate the character input (see comments). Is this going overboard? Is there a more elegant approach? How do you approach parameter validation in general? Any comments are welcome. public void setTransferType(Character typeCharacter, Character optionalSecondCharacter) throws NumberFormatException, IOException { // http://www.nsftools.com/tips/RawFTP.htm#TYPE // Syntax: TYPE type-character [second-type-character] // // Sets the type of file to be transferred. type-character can be any // of: // // * A - ASCII text // * E - EBCDIC text // * I - image (binary data) // * L - local format // // For A and E, the second-type-character specifies how the text should // be interpreted. It can be: // // * N - Non-print (not destined for printing). This is the default if // second-type-character is omitted. // * T - Telnet format control (<CR>, <FF>, etc.) // * C - ASA Carriage Control // // For L, the second-type-character specifies the number of bits per // byte on the local system, and may not be omitted. final Set<Character> acceptedTypeCharacters = new HashSet<Character>(Arrays.asList( new Character[] {'A','E','I','L'} )); final Set<Character> acceptedOptionalSecondCharacters = new HashSet<Character>(Arrays.asList( new Character[] {'N','T','C'} )); if( acceptedTypeCharacters.contains(typeCharacter) ) { if( new Character('A').equals( typeCharacter ) || new Character('E').equals( typeCharacter ) ){ if( acceptedOptionalSecondCharacters.contains(optionalSecondCharacter) ) { executeCommand("TYPE " + typeCharacter + " " + optionalSecondCharacter ); } } else { executeCommand("TYPE " + typeCharacter ); } } }

  • PostgreSQL storing paths for reference in scripts

    - by Brian D.
    I'm trying to find the appropriate place to store a system path in PostgreSQL. What I'm trying to do is load values into a table using the COPY command. However, since I will be referring to the same file path regularly I want to store that path in one place. I've tried creating a function to return the appropriate path, but I get a syntax error when I call the function in the COPY command. I'm not sure if this is the right way to go about it, but I'll post my code anyway. COPY command: COPY employee_scheduler.countries (code, name) FROM get_csv_path('countries.csv') WITH CSV; Function Definition: CREATE OR REPLACE FUNCTION employee_scheduler.get_csv_path(IN file_name VARCHAR(50)) RETURNS VARCHAR(250) AS $$ DECLARE path VARCHAR(200) := E'C:\\Brian\\Work\\employee_scheduler\\database\\csv\\'; file_path VARCHAR(250) := ''; BEGIN file_path := path || file_name; RETURN file_path; END; $$ LANGUAGE plpgsql; If anyone has a different idea on how to accomplish this I'm open to suggestions. Thanks for any help!

  • HTML forms and passing data back

    - by coLOLtip
    My html form is spreading over several pages (steps), and I want to let the use to take step back in case they would like to change something they filled in. So, I don't want to make users re-type all the information they already have typed once. Thus, how would I make it so that all the information would go back, to speak so? (I use PHP on server-side.)

  • passing paramters to component in flex

    - by dubbeat
    Hi, I've got 2 files, my Application and a custom component. In my component I have a httpservice and a string named _requestUrl that is bindable. The httpservice uses this. <mx:HTTPService id="srv" url="{_requestUrl}" result="parseHttpResult(event)" resultFormat="xml" method="GET" useProxy="false"> </mx:HTTPService> In my application file I make an instance of my component in the onCreationComplete function. In this function if I say mycomponent._urlRequest ="http://mysite.com" the httpservice throws a null url error but if I say mycomponent.srv.url="http://mysite.com" it works fine. Why is this?

  • Passing ViewData to PartialView returned from using Html.Action

    - by RWGodfrey
    I want to embed a partial view in an ASP.NET MVC page by returning it from an action method. In my base view, I would have: <%= Html.Action("MyPartialViewAction") %> My controller would have an action method like: [ChildActionOnly] public ActionResult MyPartialViewAction() { return PartialView("MyPartialView"); } I expected the returned partial view (MyPartialView) to have access to the ViewData that was set in the base page's controller action but that doesn't appear to be the case. If I insert the partial view by using the following in my base view it works: <% Html.RenderPartial("MyPartialView") %> I don't want to do that though because I want my "MyPartialViewAction" to execute logic to determine WHICH partial view to return.

  • Passing javascript form variables into jQuery function not working

    - by Chase
    I am trying to pass some JavaScript variables that I have assigned to form variables into a query string used by a jQuery plug in called fancybox.

  • Passing variable string to create arrays (Android)

    - by dweebsonduty
    Hello all, I am a newb to Android and Java and want to write a funtion that will display a list based on a varable that I pass to the function. The function is below and the code below creates an array out of a string called type, but what I want to do is pass it a variable string and have it build a list based on that string. So if I wanted the type list I would say list_it("type") But if I try something like getResources().getStringArray(R.array.thelist); it doesn't work. Can someone point me in the right direction? public void list_it(String thelist){ String[] types = getResources().getStringArray(R.array.type); ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(this, R.layout.list_item1, types); setListAdapter(mAdapter); ListView lv = getListView(); lv.setTextFilterEnabled(true); }

  • Perl, dereference array of references

    - by Mike
    In the following Perl code, I would expect to be referencing an array reference inside an array #!/usr/bin/perl use strict; use warnings; my @a=([1,2],[3,4]); my @b = @$a[0]; print $b[0]; However it doesn't seem to work. I would expect it to output 1. @a is an array of references @b is $a[1] dereferenced (I think) So what's the problem?

  • returning reference to a vector from a method and using its public members

    - by memC
    dear experts, I have a vector t_vec that stores references to instances of class Too. The code is shown below. In the main , I have a vector t_vec_2 which has the same memory address as B::t_vec. But when I try to access t_vec_2[0].val1 it gives error val1 not declared. Could you please point out what is wrong? Also, if you know of a better way to return a vector from a method, please let me know! Thanks in advance. class Too { public: Too(); ~Too(){}; int val1; }; Too::Too(){ val1 = 10; }; class B { public: vector<Too*> t_vec; Too* t1; vector<Too*>& get_tvec(); B(){t1 = new Too();}; ~B(){delete t1;}; }; vector<Too*>& B::get_tvec(){ t_vec.push_back(t1); return t_vec; } int main(){ B b; b = B(); vector<Too*>& t_vec_2 = b.get_tvec(); // Getting error std::cout << "\n val1 = " << t_vec_2[0].val1; return 0; }

  • Another passing variable through function jQuery/JS problem...

    - by dallen
    Here's my code: function mouseOver(variable) { return function() { $(variable).fadeIn(100); }; } function mouseOut(variable) { return function() { $(variable).fadeOut(100); }; } function lawyer(var1, var2, var3, var4) { return function() { $(var1).bind('mouseenter', mouseOver(var2)).bind('mouseleave', mouseOut(var2)).click( function() { $(var1).unbind('mouseenter').unbind('mouseleave'); $(var1).removeClass('off').addClass('on'); $(var3).bind('mouseenter', mouseOver(var4)).bind('mouseleave', mouseOut(var4)); $(var3).removeClass('on').addClass('off'); $(var4).hide(); }); } } lawyer("#group", ".b", "#group2", ".l"); What would be the reason for this not working? It works in that it hides $(var4).hide();, but clicking on the object doesn't seem to do anything. It works if I take the code out of a function and just copy/paste it a few times and change the targets. I'm not seeing it... Any help would be appreciated!

  • Objective-C Passing a variable to another IBAction

    - by StuR
    This works fine: NSString *myVariable; - (IBAction) doFirstAction { myVariable = @"123456789"; } - (IBAction) doSecondAction { NSLog(@"%@",myVariable); } However, if I do this (substituting the @"123456789" for some code which returns the same value ie "123456789") I cannot access the value in doSecondAction. NSString *myVariable; - (IBAction) doFirstAction { myVariable = [imageNode getAttributeName:@"value"]; } - (IBAction) doSecondAction { NSLog(@"%@",myVariable); } Any clue as to why I cant access myVariable outside of doFirstAction?

  • Iterating over member typed collection fails when using untyped reference to generic object

  • Haskell type classes and type families (cont'd)

    - by Giuseppe Maggiore
    I need some help in figuring a compiler error which is really driving me nuts... I have the following type class: infixl 7 --> class Selectable a s b where type Res a s b :: * (-->) :: (CNum n) => (Reference s a) -> (n,(a->b),(a->b->a)) -> Res a s b which I instance twice. First time goes like a charm: instance Selectable a s b where type Res a s b = Reference s b (-->) (Reference get set) (_,read,write) = (Reference (\s -> let (v,s') = get s in (read v,s')) (\s -> \x -> let (v,s') = get s v' = write v x (_,s'') = set s' v' in (x,s''))) since the type checker infers (-->) :: Reference s a -> (n,a->b,a->b->a) -> Reference s b and this signature matches with the class signature for (--) since Res a s b = Reference s b Now I add a second instance and everything breaks: instance (Recursive a, Rec a ~ reca) => Selectable a s (Method reca b c) where type Res a s (Method reca b c) = b -> Reference s c (-->) (Reference get set) (_,read,write) = \(x :: b) -> from_constant( Constant(\(s :: s)-> let (v,s') = get s :: (a,s) m = read v ry = m x :: Reference (reca) c (y,v') = getter ry (cons v) :: (c,reca) v'' = elim v' (_,s'') = set s' v'' in (y,s''))) :: Reference s c the compiler complains that Couldn't match expected type `Res a s (Method reca b c)' against inferred type `b -> Reference s c' The lambda expression `\ (x :: b) -> ...' has one argument, which does not match its type In the expression: \ (x :: b) -> from_constant (Constant (\ (s :: s) -> let ... in ...)) :: Reference s c In the definition of `-->': --> (Reference get set) (_, read, write) = \ (x :: b) -> from_constant (Constant (\ (s :: s) -> ...)) :: Reference s c reading carefully the compiler is telling me that it has inferred the type of (--) thusly: (-->) :: Reference s a -> (n,a->(Method reca b c),a->(Method reca b c)->a) -> (b -> Reference s c) which is correct since Res a s (Method reca b c) = b -> Reference s c but why can't it match the two definitions? Sorry for not offering a more succint and standalone example, but in this case I cannot figure how to do it...

Out of interest, is there any way to use the params keyword with Action<? Also, I am using C# 4.0 so I would be interested to see how it can help me in an way. Thanks

  • Passing a pointer to a function that doesn't match the requirements of the formal parameter

    - by Andreas Grech
    int valid (int x, int y) { return x + y; } int invalid (int x) { return x; } int func (int *f (int, int), int x, int y) { //f is a pointer to a function taking 2 ints and returning an int return f(x, y); } int main () { int val = func(valid, 1, 2), inval = func(invalid, 1, 2); // <- 'invalid' does not match the contract printf("Valid: %d\n", val); printf("Invalid: %d\n", inval); /* Output: * Valid: 3 * Invalid: 1 */ } At the line inval = func(invalid, 1, 2);, why am I not getting a compiler error? If func expects a pointer to a function taking 2 ints and I pass a pointer to a function that takes a single int, why isn't the compiler complaining? Also, since this is happening, what happens to the second parameter y in the invalid function?

Not all data from model you want to show in the view (for example, hashs of passwords). So you create VIEW MODEL, each for every strongly-typed-razor-view you have in application. Like this: using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace MyProject.ViewModels.SomeController.SomeAction { public class ViewModel { public ViewModel() { Entities1 = new List<ViewEntity1>(); Entities2 = new List<ViewEntity2>(); } public List<ViewEntity1> Entities1 { get; set; } public List<ViewEntity2> Entities2 { get; set; } } public class ViewEntity1 { //some properties from original DB-entity you want to show } public class ViewEntity2 { } } When you create complex client-side interfaces (I do), you use some pattern for javascript on client, MVC or MVVM (I know only these). So, with MVC on client you have another model (Backbone.Model for example), which is third model in application. It is a bit much. Why don`t we use the same ViewModel model on a client (in backbone.js or another framework)? Is there a way to transfer CS-coded model to JS-coded? Like in MVVM pattern, with knockout.js, when you can do like this: in SomeAction.cshtml: <div style="display: none;" id="view_model">@Json.Encode(Model)</div> after that in Javascript-code var ViewModel = ko.mapping.fromJSON($("#view_model").get(0).innerHTML); now you can extend your ViewModel with some actions, event handlers, etc: ko.utils.extend(ViewModel, { some_function: function () { //some code } }); So, we are not building the same view model on the client again, we are transferring existing view model from server. At least, data. But knockout.js is not suitable for me, you can`t build complex UI with it, it is just data-binding. I need something more structural, like backbone.js. The only way to build ViewModel for backbone.js I can see now is re-writing same ViewModel in JS from server with hands. Is there any ways to transfer it from server? To reuse the same viewmodel on server view and client view?

  • Passing a hostname of over 255 characters to getaddrinfo causes a getaddrinfo failed: memory allocat

    - by darrickc
    I am currently upgrading our software to support ipv6 and in the meantime I'm expanding hostname/ip fields to the max hostname size. In sun documentation it seems like this can be up to 1025 (netdb.h:#define NI_MAXHOST 1025 - this is the recommended hostname allocation define), but when I pass a hostname of over 255 to getaddrinfo I get "getaddrinfo failed: memory allocation failure". I am testing on a Sol10 box. Ideas?
