  • issue with tab bar view displaying a compound view

    - by ambertch
    I created a tab bar application, and I make the first tab a table. So I create a tableView controller, and go about setting the class identity of the view controller for the first tab to my tableView controller. This works fine, and I see the contents of the table filling up the whole screen. However, this is not what I actually want in the end goal - I would like a compound window having multiple views: - the aforementioned table - a custom view with data in it So what I do is create a nib for this content (call it contentNib), change the tab's class from the tableView controller to a generic UIViewController, and set the nib of that tab to this new contentNib. In this new contentNib I drag on a tableView and set File's Owner to the TableViewController. I then link the dataSource and delegate to file's owner (which is TableViewController). Surprisingly this does not work and I receive the error: **Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x3b0f910'** This is bewildering to me since the file's owner is the TableViewController, which has been assigned to be both the dataSource and delegate. Does someone have either insight into my confusions, or a link to an example of how to have a compound view include a tableView? *update* I see this in the Apple TableView programming guide: "Note: You should use a UIViewController subclass rather than a subclass of UITableViewController to manage a table view if the view to be managed is composed of multiple subviews, one of which is a table view. The default behavior of the UITableViewController class is to make the table view fill the screen between the navigation bar and the tab bar (if either are present)." <----- I don't really get what this is telling me to do though... if someone can explain or point me to an example I'd be much appreciated!

  • When to save a mongoose model

    - by kentcdodds
    This is an architectural question. I have models like this: var foo = new mongoose.Schema({ name: String, bars: [{type: ObjectId, ref: 'Bar'}] }); var FooModel = mongoose.model('Foo', foo); var bar = new mongoose.Schema({ foobar: String }); var BarModel = mongoose.model('Bar', bar); Then I want to implement a convenience method like this: BarModel.methods.addFoo = function(foo) { foo.bars = foo.bars || []; // Side note, is this something I should check here? foo.bars.push(this.id); // Here's the line I'm wondering about... Should I include the line below? foo.save(); } The biggest con I see about this is that if I did include foo.save() then I should pass in a callback to addFoo so I avoid issues with the async operation. I'm thinking this is not preferable. But I also think it would be nice to include because addFoo hasn't really "addedFoo" until it's been saved... Am I breaking any design best practices doing it either way?

  • Forms blank when rendering a partial when using a collection of objects. Help!

    - by dustmoo
    Alright, I know my title is a little obscure but it best describes the problem I am having. Essentially, I have a list of users, and want to be able to edit their information in-line using AJAX. Since the users are showing up in rows, I am using a partial to render the data and the forms (which will be hidden initially by the ajax), however, when the rows are rendered currently only the last item has it's form's fields populated. I suspect this has something to do with the fact that all the form fields have the same id's and it is confusing the DOM. But I don't know how to make sure the id's are unique. Here is a small example: In my view: <%= render :partial => 'shared/user', :collection => @users %> My partial (broke down to just the form) note that I am using the local variable "user" <% form_for user, :html => {:multipart => true} do |f| -%> <%= f.label :name, "Name*" %> <%= f.text_field :title, :class => "input" %> <%= f.label :Address, "Address" %> <%= f.text_field :address, :class => "input" %> <%= f.label :description, "Description*" %> <%= f.text_area :description, :class => "input" %> <% end -%> When the html is rendered each form has a unique id (for the id of the user) but the elements themselves all have the same id, and only the last user form is actually getting populated with values. Does anyone have any ideas?? :) Thanks in advance!

  • Which CSS identifier is used for the selected tab in tabbed tables in browsers other than IE?

    - by David Navarre
    When you have a table on a form in Notes, you can choose to display only one row at a time (via the Special Table Row Display parameter on the Table Rows tab of the Table properties). In a Notes document displayed using Internet Explorer that contains such a table, a row is displayed with a cell for each "tab". The TD that serves as the tab for the selected "Notes table row" is assigned <td class="dominoSelTopTab">, while the other tabs get <td class="dominoTopTab">. However, when using other browsers, it's not nearly as simple. In Firefox, each "tab" ends up as a single-celled-single-row-table within the table with very little to identify it. <td><table border="1" cellpadding="2"> <tr><td><div align="center"><b>Tab 2</b></div></td></tr> </table></td> A non-selected tab would show as follows: <td><table border="1" cellpadding="2"> <tr><td><div align="center"><a name="1." href="/Projects/MyCSS.nsf/0c3b9489476440c085257a62006d97d6/d482a1767a4af77f85257a62006db064?OpenDocument&amp;TableRow=1.0#1." target="_self">Tab 1</a></div></td></tr> </table></td> So, the question is, how do I identify the selected tabs and the non-selected tabs when not using IE? Note: For those who are not Notes developers, the HTML is auto-generated from the visual design as laid out in the Notes designer client. I would replace it all with manual HTML, except there is so much of it that doing so would consume far too much time.

  • Why do touches only get detected ABOVE my CCBitmapFontAtlas and not ON it? (cocos2d)

    - by RexOnRoids
    I am detecting touches for CCBitmapFontAtlas (just text labels) as shown in the code below. But it seems that touches are only detected slightly ABOVE the CCBitmapFontAtlases? Did something get screwed when converting between coordinate systems? (*Note objects label1, label2, etc are CCBitmapFontAtlas) - (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { for( UITouch *touch in touches ) { CGPoint location = [touch locationInView:[touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; self.myGraphManager.isSliding = NO; CGRect rectLabel1 = CGRectMake(label1.position.x, label1.position.y, label1.contentSize.width, label1.contentSize.height); CGRect rectLabel2 = CGRectMake(label2.position.x, label2.position.y, label2.contentSize.width, label2.contentSize.height); CGRect rectLabel3 = CGRectMake(label3.position.x, label3.position.y, label3.contentSize.width, label3.contentSize.height); CGRect rectLabel4 = CGRectMake(label4.position.x, label4.position.y, label4.contentSize.width, label4.contentSize.height); CGRect rectLabel5 = CGRectMake(label5.position.x, label5.position.y, label5.contentSize.width, label5.contentSize.height); CGRect rectLabel6 = CGRectMake(label6.position.x, label6.position.y, label6.contentSize.width, label6.contentSize.height); if(CGRectContainsPoint(rectLabel1, location)){ NSLog(@"Label 1 Touched"); }else if(CGRectContainsPoint(rectLabel2, location)){ NSLog(@"Label 2 Touched"); }else if(CGRectContainsPoint(rectLabel3, location)){ NSLog(@"Label 3 Touched"); }else if(CGRectContainsPoint(rectLabel4, location)){ NSLog(@"Label 4 Touched"); }else if(CGRectContainsPoint(rectLabel5, location)){ NSLog(@"Label 5 Touched"); }else if(CGRectContainsPoint(rectLabel6, location)){ NSLog(@"Label 6 Touched"); } } }

  • jQuery logic firing twice from a Usercontrol when used in a jQueryUI modal dialog

    - by AaronS
    I have an asp.net usercontrol that I'm using to put a bunch of HTML and Jquery logic into to be shared on several pages. This usercontrol has some dropdown boxes loaded from json calls and has no added codebehind logic. When I use this usercontrol on a normal page it works perfectly fine, and no issues at all. However, when I wrap the usercontrol in a div, and use a jqueryUI modal dialog, everything in the usercontrol fires twice. Not only code in the initial $(document).ready(function() {});, but also every function is also fired twice when called. Debugging this in Visual Studio, I see that everything is first being called from the external JS file, and then again from a "script block" file that is somehow getting generated on the fly. This script block file isn't getting generated on a page that doesn't wrap the user control in a modal. The same happens if I use IISExpress or IIS7. The question is, why is this script block file getting created, and why is all my jQuery logic firing twice? --edit-- Here is the div: <div id="divMyDiv" title="MyDiv"> <uc1:MyUserControl runat="server" ID="MyUsercontrol" /> </div> Here is the modal logic that uses it: $("#divMyDiv").dialog({ autoOpen: false, height: 400, width: 400, modal: true, open: function (type, data) { $(this).parent().appendTo("form"); } }); Note: The problm still occurs, even if I remove the "open:" function. But, it does not occur if I remove the entire dialog block, so it is specific to this dialog call.

  • Dynamic content in a Gridview

    - by mariki
    I have a gridview with couple of columns,I want to achieve the following: If user is NOT authorized display normal columns. If user IS authorized: set mouseover event for first column text and display some buttons (that are not available for NOT authorized users) in a second column when user hover over(using javascript) the first column. I am have 2 difficulties: The first one where and when should I create the buttons? I have 2 options, I can create those button on design time, in gridviews template and just set Visible value to false and then in codebehind set it to true if user is authorized. The second option would be creating this buttons dynamically in gridview_RowCreated event (or any other event) if user is authorized. The Second difficulty is setting the javascript event to show the buttons, the event should be added only if user is authorized! Note that event and buttons should have some kind of id match for Javascript function to know what should it hide/unhide when event is triggered. What should I do, what is the best practice? I know this is a long question, but please try to help :)

  • measure the response time of a link

    - by Ahoura Ghotbi
    I am trying to create a simple load balance script and I was wondering if it is possible to find the response time of a server live? By that I mean is it possible to measure how long it takes for a server to respond after the request has been sent out? What I am trying to do is fairly simple, I want to send a request to a link/server and do a count down, if the server took more than 5 seconds to reply, I would like to fall on the backup server. Note that it doesnt have to be in pure php, I wouldnt mind using other languages such as javascript, C/C++, asp, but I prefer to do it in PHP. if it is possible to do the task, could you just point me to the right direction so I can read up on it. Clarification What I want to do is not to download a file and see how long it took, my servers have high load and it takes a while for them to respond when you click on a file to download, what I want to do is to measure the time it takes the server to respond (in this situation, its the time it takes the server to respond and allow the user to download the file), and if it takes longer than x seconds, it should fall back on a backup server.

  • Can't authenticate mobile client with node.js (using passport.js)

    - by Pazinio
    I'm trying to build some CRUD application with node.js as a back-end API (express) and web-app (backbone) and mobile client (native android) as front-ends.(I'm node.js beginner) My server solution is based on the following great tutorial 'easy-node-authentication'. In my android app I have managed to get the user Google-Token after I completed the authentication step with Google Plus SDK.(mobile to google-plus directly request). I'm trying to understand and find right and elegant way to re-use a given google-token and authenticate again my android user through Google-Plus account to ensure the mobile client holds real token, then add a new entry (id, token, email, name) to my users table DB within my node back-end. The question is: what should be my next step in case I want to keep my back-end without changes? should I send a GET request with the token as a cookie to /auth/google? maybe to /auth/google/callback? another URL? Does this make sense at all? Please note: I'm aware to the fact the mentioned above 'easy-node-auth' solution is based on sessions and cookies. having said that, i'm still trying to understand if there is a convenient way to integrate both (android and node) as it works good for my web-app and node. Thanks in advance.

  • Browse for folder can't see camera device

    - by Robert Frank
    In Delphi 2010, I want to allow users to browse and select a folder. The folder is on a device (?) created by a DSLR: The folder is visible in the Windows Explorer as shown above. And, the folder is visible in a TOpenDialog, allowing them to browse into the folder and choose a file. Unfortunately, I have been unable to get either SHBrowseForFolder (code I found on the web but don't understand) or SelectDirectory to see the camera device or folder beneath it. (Side note: IMO, SelectDirectory is a far nicer UI, since the user can see the files in the folders while browsing.) I assume this has to do with the fact that the folder is in a device (?) created by the camera software. I've seen some tricks where you call TOpenDialog to browse for folders with '*.' and then ExtractFileDir on the result, but that's not robust or, IMO, a good UI. What I'm looking for is a "Browse for folder" that can see the same devices (including the camera device) the TOpenDialog & Windows Explorer can see. (Ideally, it would have the nice appearance like the one below!) Any suggestions? Image of a MS-Word's folder browsing in Win7. (I wonder if it looks this pretty in XP.)

  • C++ Vector of vectors is messing with me

    - by xbonez
    If I put this code in a .cpp file and run it, it runs just fine: #include <iostream> #include <vector> #include <string> using namespace std; typedef vector<int> row; typedef vector<row> myMatrix; void main() { //cout << endl << "test" << endl; myMatrix mat(2,2); mat[0][1] = 2; cout << endl << mat[0][1] << endl; } But, if I make a .h and a .cpp file with the .h file like this, it gives me boatloads of errors. #ifndef _grid_ #define _grid_ #include<iostream> #include<vector> #include<string> using namespace std; typedef vector<int> row; typedef vector<row> myMatrix; class grid { public: grid(); ~grid(); int getElement(unsigned int ri, unsigned int ci); bool setElement(unsigned int ri, unsigned int ci, unsigned int value); private: myMatrix sudoku_(9,9); }; #endif These are some of the errors I get: warning C4091: 'typedef ' : ignored on left of 'int' when no variable is declared error C4430: missing type specifier - int assumed.

  • What is the strangest programming language you have used?

    - by Anders Sandvig
    For me I think it has to be the scripting language of an old proprietary telephony platform I used in the early 2000s. The language itself was not so bad, but the fact that it was meant to be edited with a drag-and-drop GUI, which did not expose all the functionality I needed, was quite frustrating. I also remember having to manually implement many common functions, such as calculating the length of a string. Whenever I wanted to use "custom" or "advanced" functions, I had to edit the script files in a text editor, but as soon as I opened the files in the GUI again they were reformatted and restructured, which usually resulted in broken code. And, of course, this was an interpreted language, so I would not know it was broken until I actually ran it—oh, and did I mention that it did not run the same in the simulator as in the live environment? So, what is the strangest programming language or environment you have used, and why did you use it? Note that I'm interested in languages and environments that you have actually used for "real-world" situations, so Whitespace, Brainf***k and friends are not valid—unless you have used them for something "real", of course.

  • Storing large numbers of varying size objects on disk

    - by Foredecker
    I need to develop a system for storing large numbers (10's to 100's of thousands) of objects. Each object is email-like - there is a main text body, and several ancillary text fields of limited size. A body will be from a few bytes, to several KB in size. Each item will have a single unique ID (probably a GUID) that identifies it. The store will only be written to when an object is added to it. It will be read often. Deletions will be rare. The data is almost all human readable text so it will be readily compressible. A system that lets me issue the I/Os and mange the memory and caching would be ideal. I'm going to keep the indexes in memory, using it to map indexes to the single (and primary) key for the objects. Once I have the key, then I'll load it from disk, or the cache. The data management system needs to be part of my application - I do not want to depend on OS services. Or separately installed packages. Native (C++) would be best, but a manged (C#) thing would be ok. I believe that a database is an obvious choice, but this needs to be super-fast for look up and loading into memory of an object. I am not experienced with data base tech and I'm concerned that general relational systems will not handle all this variable sized data efficiently. (Note, this has nothing to do with my job - its a personal project.) In your experience, what are the viable alternatives to a traditional relational DB? Or would a DB work well for this?

  • Prevent jQuery Tabs to bind to <ul> elements below the main <ul> element.

    - by Shiki
    Hi, I have this HTML: <div id="mytabs"> <ul id="main-tabs"> <li><a href="">Link</a></li> <li><a href="">Link</a></li> <li class="filter"> <ul id="filter-controls"> <li><a href="">Filter by something</a></li> <li><a href="">Filter by something</a></li> <li><a href="">Filter by something</a></li> </ul> </li> </ul> </div> And I set it to a tabbed control: $('#mytabs').tabs(); My problem is jQuery UI also converts the <li> elements in <ul id="filter-controls"> into tabs. Is there a way to instruct jQuery UI to only set the <li> children of <ul id="main-tabs"> as the tabs? Note: I am currently in no position to change <ul id="filter-controls" into a non-ul element.

  • How to style "form" field labels in Windows Phone 7?

    - by Jeremy Bell
    Is there any standards guidance on how to style field labels next to form fields in windows phone 7 silverlight applications? For example, let's say I have a StackPanel with the TextBlock label and a TextBox for data entry. Currently I am using the default TextBlock Margin included in the PhoneTextSubtleStyle ("12,0,12,0"), and using a Margin of "0,-12,0,0" to push the TextBox up closer to the label: <StackPanel HorizontalAlignment="Left"> <TextBlock VerticalAlignment="Center" Text="Name" Style="{StaticResource PhoneTextSubtleStyle}" /> <TextBox Text="{Binding ItemName, Mode=TwoWay}" TextChanged="TextBox_TextChanged" VerticalAlignment="Center" Width="433" Margin="0,-12,0,0" /> </StackPanel> Note that the TextBox seems to have some internal padding of 12 pixels to the left and right, so that the TextBlock label and the TextBox control visually line up perfectly on the left. The problem is, I see existing apps with widely varying conventions for field label styling. Some do not do the negative margin adjustment, like I have above. Some don't. Some appear to override the label TextBlock Margin so that it is indented an additional 12 pixels on the left (i.e. "24,0,12,0" instead of the default "12,0,12,0"). Some apps put the labels to the left of the fields themselves (I hate that). Is there some standard design guidance on field labels in Windows Phone 7? I read through the design template PDF and could only determine that the field labels should be upper case on the first word (preferably only one word labels), and should NOT have a colon at the end. I didn't see anything with regards to margins or alignment between the label and the field.

  • The HTTP verb POST used to access path '[my path]' is not allowed.

    - by Jed
    I am receiving an error that states: "The HTTP verb POST used to access path '[my path]' is not allowed.". The error is being caused by the fact that I am implementing an HTML form element that uses the POST method and does not explicitly define an .aspx page in its ACTION parameter. For example: <form action="" method="post"> <input type="submit" /> </form> The HTML above is on a file at "/foo/default.aspx". Now, if the user points the URL to the root directory "foo" without specifying the aspx file (i.e. "http://localhost/foo") and then submits the form, the error "The HTTP verb POST used to access path '/foo' is not allowed." will be thrown. However, if the user goes to "http://localhost/foo/default.aspx" and then submits the form, all goes well (even if the ACTION parameter is left empty). Note: If I explicitly add the name of the .aspx (default.aspx) page to the ACTION parameter, no errors are thrown. So the example below works fine regardless if the user defines the name of the file in the URL or not. <form action="default.aspx" method="post"> <input type="submit" /> </form> I was curious as to why the error was being thrown, so I read a Microsoft KB that states This problem occurs because a client makes an HTTP request by sending the POST method to a static HTML page. Static HTML pages do not support the POST method. I suppose the core of the explanation makes sense, however in my case, my form is not being sent to a static html page - it's being sent to the same page that the html form lives on (default.aspx)... this is implicit to an ACTION param that is left empty. Is it possible to configure IIS (or otherwise) that will allow us to do form POSTing and keep the ACTION param empty?

  • casting char[][] to char** causes segfault?

    - by Earlz
    Ok my C is a bit rusty but I figured I'd make my next(small) project in C so I could polish back up on it and less than 20 lines in I already have a seg fault. This is my complete code: #define ROWS 4 #define COLS 4 char main_map[ROWS][COLS+1]={ "a.bb", "a.c.", "adc.", ".dc."}; void print_map(char** map){ int i; for(i=0;i<ROWS;i++){ puts(map[i]); //segfault here } } int main(){ print_map(main_map); //if I comment out this line it will work. puts(main_map[3]); return 0; } I am completely confused as to how this is causing a segfault. What is happening when casting from [][] to **!? That is the only warning I get. rushhour.c:23:3: warning: passing argument 1 of ‘print_map’ from incompatible pointer type rushhour.c:13:7: note: expected ‘char **’ but argument is of type ‘char (*)[5]’ Are [][] and ** really not compatible pointer types? They seem like they are just syntax to me.

  • Mercurial: Class library that will exist for both .NET 3.5 and 4.0?

    - by Lasse V. Karlsen
    I have a rather big class library written in .NET 3.5 that I'd like to upgrade to make available for .NET 4.0 as well. In that process, I will rip out a lot of old junk, and rewrite some code to better take advantage of the new classes and support in .NET 4.0 (like TPL.) The class libraries will thus diverge, but still be similar enough that some bug-fixes can be done to both in the same manner. How should I best organize this class library in Mercurial? I'm using Kiln (fogbugz) if that matters. I'm thinking: Named branches in one repository, can then transplant any bugfixes from one to the other Unnamed branches in one repository, can also transplant, but I think this will look messy Separate repositories, will have to reimplement the bugfixes (or use a non-mercurial-integraded compare tool to help me) What would you do? (any other alternatives that I haven't though of is welcome as well.) Note that the class libraries will diverge pretty heavily in areas, I have some remnants of old collection-type code that does something similar to Linq that I will remove, and some code that uses it that I will rewrite to use the Linq-methods instead. As such, just copying the project files and using #if NET40..#endif sections is not going to work out. Also, the 3.5 version of the class library will not be getting many new features, mostly just critical bug-fixes, so keeping both versions equally "alive" isn't really necessary. Thus, separate copies of all the files are good enough.

  • Discussion - Allowing / blocking user access to pages / Client Side Validation (Client Side Only!) -

    - by Ozaki
    TLDR Using plain HTML / Javascript (Client Side) I want to prevent viewing of certain pages. The user will have to type a username and password and depending on that they get access to different pages. Answers can NOT include server side whatsoever It does not matter if they can break it easily. There is no sensitive information etc. Also the target audience will not have access to internet OR probably know what a cookie is... At some point the user will have to type username / password.(I can define the cookie here) Currently I thought of using cookies to set a cookie for each page to say "true" / "false" but that would get messy with so many cookies. Or setting an array within a cookie for each page? I have div field "#Content" which as it looks encompasses all of my content on the page so blocking out content will be as simple as replacing it with ("sorry you don't have access") etc. For Example: $.cookie("Access","page1, page2, page3"{ expires: 1 }); I am looking for anyway to do this does not have to be with cookies. Would be nice to get a discussion of different ways this can be done. So the question is: What do YOU think would be a good way to go about doing this with client side validation? Also on another note discussion on how to make client side more secure or ways to do so are acceptable.

  • .htaccess file on localhost throwing an error when using a Virtual Host config on my Localhost!!

    I am trying to set-up my localhost development server. I have everything working but when I try to add an .htaccess it throws this error: Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

  • C++ Type error with Object versus Object reference

    - by muddybruin
    I have the following function (which worked in Visual Studio): bool Plane::contains(Vector& point){ return normalVector.dotProduct(point - position) < -doubleResolution; } When I compile it using g++ version 4.1.2 , I get the following error: Plane.cpp: In member function âvirtual bool Plane::contains(Vector&)â: Plane.cpp:36: error: no matching function for call to âVector::dotProduct(Vector)â Vector.h:19: note: candidates are: double Vector::dotProduct(Vector&) So as you can see, the compiler thinks (point-position) is a Vector but it's expecting Vector&. What's the best way to fix this? I verified that this works: Vector temp = point-position; return normalVector.dotProduct(temp) < -doubleResolution; But I was hoping for something a little bit cleaner. I heard a suggestion that adding a copy constructor might help. So I added a copy constructor to Vector (see below), but it didn't help. Vector.h: Vector(const Vector& other); Vector.cpp: Vector::Vector(const Vector& other) :x(other.x), y(other.y), z(other.z), homogenous(other.homogenous) { }

  • Getting the value of an input inside a td for each row with jQuery

    I am still having so many problems with this: function padTitles() { $('tr').each(function () { var tds = $(this).find('input'), text = tds.filter('[id^="TempRowKey_"]').val(), tdToPad = tds.filter('[id^="title_"]'), pad; if (/0\.0$/.test(text)) pad = 10; else if (/\.0$/.test(text)) pad = 35; else pad = 60; tdToPad.css('paddingLeft', pad); }); } Note: here is what I was using before. This worked when the value was not inside an input: var tds = $(this).find('td'), text = tds.filter('[id^="refKey_"]').text(), It is supposed to get the Value of the Inputs with id's that start with TempRowKey_ and then use these for padding. But the code does nothing. Here is my HTML: <tr id="row_1"> <td id="tempRowKey_1" > <input type="text" size="10" value="1.0.0" class="updatable" id="TempRowKey_1"> </td> <td id="title_1"> <input id="Title_1" class="updatable" type="text" value="zxxx" size="100" name="item.Title"> </td>. <td ... </tr> Is there some way I can test this. I can't get access to anything inside the jQuery block?

  • need help with C++ using maps to keep track of words in a INPUT file

    - by eNetik
    Let say i have a text file with today is today but tomorrow is today tomorrow then using maps how can i keep track of the words that are repeated? and on which line it repeats? so far i have each string in the file read in as a temp and it is stored in the following way: map<string,int> storage; int count = 1 // for the first line of the file if(infile.is_open()){ while( !infile.eof() ){ getline(in, line); istringstream my_string(line); while(my_string.good()){ string temp; my_string >> temp; storage[temp] = count } count++;// so that every string read in the next line will be recorded as that line. } } map<string,int>::iterator m; for(int m = storage.begin(); m!= storage.end(); m++){ out<<m->first<<": "<<"line "<<m->second<<endl; } right now the output is just but: line 1 is: line 2 today: line 2 tomorrow: line 2 But instead.. it should print out(no repeating strings): today : line 1 occurred 2 times, line 2 occurred 1 time. is: line 1 occurred 1 time, line 2 occurred 1 time. but: line 1 occurred 1 time. tomorrow: line 2 occurred 2 times. Note: the order of the string does not matter. Any help would be appreciated. Thanks.

  • Why is textbox.focus throwing the lostfocus event?

    - by cost
    I've seen a few similar questions on SO but nothing that seems to actually address the issue. Here's a simplified version of the function. Private Sub Check_Quantity(sender As System.Object, e As System.Windows.RoutedEventArgs) _ Handles textbox_quantity.LostFocus Dim worked As Boolean = Integer.TryParse(textbox_quantity.Text, quantity) If Not worked Then MsgBox("Enter a valid number for the quantity") textbox_quantity.Focus() textbox_quantity.SelectAll() quantity = 0 End If End Sub It's important to note that this is WPF. What I want to do is very simple. When someone finishes with the textbox the program checks that what they entered is a number. If it does it sticks this in an integer. If not, it tells them to fix it and keeps the focus on the textbox. The issue is a few things, but what it comes down to is this function runs in an infinite loop. This same function works fine in WinForms, but not in WPF. On some other questions people have said that the messagebox appearing causes focus to be lost, but in testing this isn't true. It still loops regardless of if the messagebox is called or not. The problem is the call to textbox_quantity.Focus(). Without that it works fine. Regardless of whether it's there or not though, focus is not set to the textbox, though textbox_quantity.Focus() still returns a value of true. Any thought of what's going on and maybe how I could fix it?

  • Class lookup structure array in C++

    - by wyatt
    I'm trying to create a structure array which links input strings to classes as follows: struct {string command; CommandPath cPath;} cPathLookup[] = { {"set an alarm", AlarmCommandPath}, {"send an email", EmailCommandPath}, {"", NULL} }; which will be used as follows: CommandPath *cPath = NULL; string input; getline(cin, input); for(int i = 0; cPathLookup[i] != ""; i++) { if(cPathLookup[i].command == input) cPath = new cPathLookup[i].cPath; } Obviously, this code is meaningless, but I think my intention is apparent - depending on input, I'd like cPath to be initialized as either a new AlarmCommandPath or a new EmailCommandPath. I could handle it with a function returning an instance depending on input, but a whole sequence of ifs just seems inelegant. I should also note that, in case it's not apparent and important, that AlarmCommandPath and EmailCommandPath are derived from CommandPath, and CommandPath is an abstract class. Thanks for any help you can offer. EDIT: I just noticed that, in spite of CommandPath being abstract, I have a declaration: CommandPath *cPath = NULL; in working code. Why does that compile?
