• Which features do html form elements miss

  - by Bakhtiyor

  I just wondered and wanted to gather together in one place all missing features of our beloved html form elements. One example could be missing of horizontal scrollbar in a listbox. But I am sure there are a lot of features we would like to see in our form elements by default. I order to be clear let's only take into account HTML4, because with HTML5 there are a lot of things haven't been finished yet. One missing feature per answer please. Thank you.

• C++ How do I properly use getline for ifstream members.

  - by John

  Ok so I have a problem with getline. I have a file that contains a couple strings. I created it by myself and I have each string on a seperate line. Ex. textfile.txt Line 1 Line 2 Line 3 Line 4 //Little snip of code ifstream inFile("textfile.txt"); getline(inFile, string1); When I debug the program and ask it to print out string1 it shows that "Line 1\r" is saved into string1. I understand that it's from me actually hitting enter when I created the file. This problem causes my program to have a segmentation fault. I know my code works because if I use ofstream to write the file first and then i read it in, it works. So for my quesiton, is their anyway to use the getline function without it picking up the escape sequence \r? If i am not clear just let me know.

• Integration of Magento with third party CRM, POS and ERP solutions

  - by SIA

  Hi there, First of all I would like to Thank the Varien Company for providing the best ecommerce solution and free community edition. I am very excited since i started knowing about magento. I am a web developer and very much interested. I have some concerns about the Integration of Magento with other CRM,ERP systems. How is it possible to integrate Magento with any other Industry standard CRM and ERP system? How can i fetch the data from a ERP and update Magento database, like transactiona replication. Is this possible? And Whats the right way to do it? Also, How can i integrate Magento with POS? Is it possible to have bi-directional data update between Magento and Industry Standard POS? I hope I have stated all my doubts and made it clear. I would be thankful if someone guides me to do the integration, the Right way. Thanks and Regards SIA

• Design pattern for mouse interaction

  - by mike

  I need some opinions on what is the "ideal" design pattern for a general mouse interaction. Here the simplified problem. I have a small 3d program (QT and openGL) and I use the mouse for interaction. Every interaction is normally not only a single function call, it is mostly performed by up to 3 function calls (initiate, perform, finalize). For example, camera rotation: here the initial function call will deliver the current first mouse position, whereas the performing function calls will update the camera etc. However, for only a couple of interactions, hardcoding these (inside MousePressEvent, MouseReleaseEvent MouseMoveEvent or MouseWheelEvent etc) is not a big deal, but if I think about a more advanced program (e.g 20 or more interactions) then a proper design is needed. Therefore, how would you design such a interactions inside QT. I hope I made my problem clear enough, otherwise don't bother complain :-) Thanks

• Presentation to under privileged students about what programming is. How? Any ideas.

  - by Quigrim

  Next week I have to give a presentation to a group of under privileged college students about the possibilities of a career in software development. These students have no exposure to programming what-so-ever. I have a good idea of how to tackle the non-technical, general portion of the presentation. However, notwithstanding my decade of experience, I am finding myself at somewhat of a loss how to convey the concept of programming in a meaningful way in under 20 minutes. Do I demonstrate actual simple code, or do I stick with concepts? I need to be able to scratch the surface of the vastness of the programming realm, to create just enough of a handle to those students, to peak the interest of those who might have the aptitude for it. Any ideas that are concise and clear would be greatly appreciated. Also, if anybody knows of online resources that addresses this topic, please share. Looking forward to some great input from this community. Thank you.

• NSStrings, C strings, pathnames and encodings in iPhone

  - by iter

  I am using libxml2 in my iPhone app. I have an NSString that holds the pathname to an XML file. The pathname may include non-ASCII characters. I want to get a C string representation of the NSString for to pass to xmlReadFile(). It appears that cStringUsingEncoding gives me the representation I seek. I am not clear on which encoding to use. I wonder if there is a "default" encoding in iPhone OS that I can use here and ensure that I can roundtrip non-ASCII pathnames.

• Drag and drop an image from desktop to a web text editor (implementation in javascript)

  - by fatmatto

  I tried to write reasonably short title but i failed i guess.. Hi everybody here's what i'm trying to do: I want to implement a web text editor able to recognize when the user drag a image file over it's editing surface and it automa(gically) starts the upload and insert the image near the cursor position. In other words i don't want the user to do the usual "insert-image-browse-ok". Atm i am not very good at javascript ... i know JQuery but i have not a clear idea about how to implement this... i don't know if there's an event handler able to help me in this situation... if not then there should be i think or web apps would miss some kind of interactivity. I've heard miracles about HTML5 could it help me? I've seen such things in Google Wave but that surface doesn't seem to be a form field... google lab's black magic i guess.... Thank you in advance.

• Migrating from Clearcase LT (UCM) to Subversion

  - by user300199

  I am sure this question has been asked hundreds of time and been responded equally. I am trying to get a clear picture of my effort before I embark on this. I want to know if SVNImporter or any other tool out there helps me migrate my UCM VOBs to Subversion repos. I dont mind losing some history. Also please share your strategies if there are no tools out there. I was told by someone that I would have to rebase my view with each baseline from oldest to the newest and incrementally commit that code into Subversion. While this seems to be plain and simple but considering the number of VOBs we have here, this would be a gigantic task for us to do manually. Is there any script out there that I can use to automate this process. Comments please!!! Thanks Gnan

• How can I support conditional validation of model properties

  - by Jeff

  I currently have a form that I am building that needs to support two different versions. Each version might use a different subset of form fields. I have to do this to support two different clients, but I don't want to have entirely different controller actions for both. So, I am trying to come up with a way to use a strongly typed model with validation attributes but have some of these attributes be conditional. Some approaches I can think of is similar to steve sanderson's partial validation approach. Where I would clear the model errors in a filter OnActionExecuting based on which version of the form was active. The other approach I was thinking of would to break the model up into pieces using something like class FormModel { public Form1 Form1Model {get; set;} public Form2 FormModel {get; set;} } and then we would validate appropriately depending on

• Changing the size of the UISearchBar TextField ?

  - by Padraig

  I have a UITableView with an Index on the side; I want to add a UISearchBar to it, but the index overlaps with the "x" to clear the search. I've noticed in the Contacts application, the textfield within the UISearchBar is resized to accommodate this, but I can't work out how to do this in my own app. I have tried the following in my viewDidLoad, but it does not seem to work. UITextField * textField = (UITextField *)[[self.search subviews] objectAtIndex:0]; CGRect r = textField.frame; [textField setFrame:CGRectMake(r.origin.x, r.origin.y, r.size.height, r.size.width-30)]; Any ideas?

• Best Dijkstra papers to explain this quote?

  - by jemfinch

  I was enjoying "The Humble Programmer" earlier today and ran across this choice quote: Therefore, for the time being and perhaps forever, the rules of the second kind present themselves as elements of discipline required from the programmer. Some of the rules I have in mind are so clear that they can be taught and that there never needs to be an argument as to whether a given program violates them or not. Examples are the requirements that no loop should be written down without providing a proof for termination nor without stating the relation whose invariance will not be destroyed by the execution of the repeatable statement. I'm looking for which of Dijkstra's 1300+ writings best describe in further detail rules such as he was describing above.

• Building NDK app with Android ADT on Windows

  - by Michael Sh

  While there are tons of information on the topic, there is no clear guide on how to compile C++ code in ADT. Is Cygwin is required? Where the build artifacts go? How to confogure the destination folder for the build package? Are there a debug and release versions? Is it possible to debug and step through the C++ code in ADT? Maybe it all is described in a single resource, then a link would be welcome!

• Multiple Asserts in a Unit Test

  - by whatispunk

  I've just finished reading Roy Osherove's "The Art of Unit Testing" and I am trying to adhere to the best practices he lays out in the book. One of those best practices is to not use multiple asserts in a test method. The reason for this rule is fairly clear to me, but it makes me wonder... If I have a method like: public Foo MakeFoo(int x, int y, int z) { Foo f = new Foo(); f.X = x; f.Y = y; f.Z = z; return f; } Must I really write individual unit tests to assert each separate property of Foo is initialized with the supplied value? Is it really all that uncommon to use multiple asserts in a test method? FYI: I am using MSTest.

• How to access Grails domain classes in Java service layer?

  - by batmannavneet

  How can I use grails domain classes (which is in groovy) in service layer which is in Java/Spring. When using the grails MVC, everything is fine as I can use controller to access domain objects and call CRUD and other dynamic methods on them. But, what I am wondering is is there a clean way to do it from Java - say the service layer. For example, I may want to develop a reporting framework where I need to use domain objects to access the DB. I Hope the question is clear. This should be a standard problem that everybody must have faced in a reasonably sized project. I am just wondering how it is solved..maybe I am missing something here. thanks.

• Bitfield With 3 States...?

  - by TheCloudlessSky

  I'm trying to create an authorization scheme for my ASP.NET MVC application where an Enum is used to set permissions. For example: [Flags] enum Permissions { ReadAppointments = 1, WriteAppointments = 2 | ReadAppointments, ReadPatients = 4, WritePatients = 8 | ReadPatients, ReadInvoices = 16, WriteInvoices = 32 | ReadInvoices ... } But I don't really like that because it really doesn't make it clear that Write always includes Read. I then realized that a requirement would be that a user might have NO access to, for example, Appointments. Essentially, I'd want a "bitfield" with 3 states: none, readonly, full (read/write). I'd like to still use an enum bitfield since it's easy to store in a DB (as an int). Also it's very easy to see if a permission is set. Does anyone have any idea how this could be easily accomplished using an Enum... or am I going in the completely wrong direction?

• Different background colors for the top and bottom of a UITableView

  - by Aaron Brethorst

  If you look at your Inbox in iPhone OS 3.0's Mail app, you'll see that swiping down displays a grayish background color above the UISearchBar. Now, if you scroll down to the bottom of the table, you'll see that the background color at that end is white. I can think of a couple ways of solving this problem, but they're pretty hacky: Change the table view's background color depending on the current scrollOffset by overriding -scrollViewDidScroll: Give the UITableView a clear background color and then set its superview's backgroundColor to a gradient pattern image. Does anyone know what the "best practice" solution is for this problem? thanks.

• any way to get sharepoint groups with a given site url

  - by standley-nguyen

  Hi all. I'm getting a stuck. Suppose that I create 5 sites. For each one, I create a few sharepoint groups. So, I create a dropdownlist control to bind 5 sites and when I click on any site there, I will get sharepoint groups created on it. But I always see the dropdownlist used to bind these groups still never change. I mean it only binds a few default groups in sahrepoint everytime. The new created groups is not. And I have confusion like this web.AssociatedGroups web.Groups web.SiteGroups which one we will use this case ? Please guide me Here my snippet code private void BindSPGroupsToDropDownList(DropDownList ddl, string siteUrl) { ddl.Items.Clear(); try { SPSecurity.RunWithElevatedPrivileges(delegate() { using (SPSite site = new SPSite(siteUrl)) { using (SPWeb web = site.OpenWeb()) { //web.SiteGroups foreach (SPGroup spGroup in web.Groups) { ddl.Items.Add(new ListItem(spGroup.Name.Trim(), spGroup.ID.ToString())); } } } }); } } thanks in advance

• How to set default values to all wrong or null parameters of method?

  - by Roman

  At the moment I have this code (and I don't like it): private RenderedImage private RenderedImage getChartImage (GanttChartModel model, String title, Integer width, Integer height, String xAxisLabel, String yAxisLabel, Boolean showLegend) { if (title == null) { title = ""; } if (xAxisLabel == null) { xAxisLabel = ""; } if (yAxisLabel == null) { yAxisLabel = ""; } if (showLegend == null) { showLegend = true; } if (width == null) { width = DEFAULT_WIDTH; } if (height == null) { height = DEFAULT_HEIGHT; } ... } How can I improve it? I have some thoughts about introducing an object which will contain all these parameters as fields and then, maybe, it'll be possible to apply builder pattern. But still don't have clear vision how to implement that and I'm not sure that it's worth to be done. Any other ideas?

• How to reset input field in the iframe?

  - by user244394

  Hi! I have a search input field on the header of the page and when searched the result are displayed in an iframe, which also has the search input box on the iframe. Problem is how do I go about reseting the input value in the iframe search input field? It seem to remember the old search from the header, so when you do a search again in the iframe it display the last search, instead of the new search keyword. You have to refresh or clear the search again to make the search work correctly. Thanks in advance

• Problems using User model in django unit tests

  - by theycallmemorty

  I have the following django test case that is giving me errors: class MyTesting(unittest.TestCase): def setUp(self): self.u1 = User.objects.create(username='user1') self.up1 = UserProfile.objects.create(user=self.u1) def testA(self): ... def testB(self): ... When I run my tests, testA will pass sucessfully but before testB starts, I get the following error: IntegrityError: column username is not unique It's clear that it is trying to create self.u1 before each test case and finding that it already exists in the Database. How do I get it to properly clean up after each test case so that subsequent cases run correctly?

• All site interaction through a single page

  - by Jacques Wolfghang

  Hi there I have an idea for a site where there would be no refreshing and all interactions take place via AJAX. The page would load with central space, where all interaction would take place. If a user clicked on a link, the page would request it via AJAX and replace the rectangle's content with the link content. The idea is effectively an AJAX implemented iframe. Are there any disadvantages with this approach? Does anyone have any suggestions or thoughts on the idea? Thank You for your time Note: I am sorry if it is not clear or hard to understand, English is not my mother tongue. If there is anything you would like made clearer, please comment and I will try my best to make it understood.

• Managing the localization of Java properties files

  - by andri

  I have a Web application written in Java that is targeting several countries, all of which speak different languages (and more often than not, several languages -- that's Europe for you). We have a bunch of .properties files that hold the localized strings, and our current procedure is to e-mail the language-specific files to our partners for updating before doing major updates. However, this process is rather error-prone, as sometimes people forget to translate new strings and sometimes new strings don't get added to every language file, thus small mistakes get through very easily. Does anyone know of any existing software that could help us clear this mess? At a bare minimum, I'm thinking of something that would allow you to load a master file (for example, in English), a localized file and then would highlight the keys that were added to or removed from the master file.

• does a switch idiom make sense in this case?

  - by the ungoverned

  I'm writing a parser/handler for a network protocol; the protocol is predefined and I am writing an adapter, in python. In the process of decoding the incoming messages, I've been considering using the idiom I've seen suggested elsewhere for "switch" in python: use a hash table whose keys are the field you want to match on (a string in this case) and whose values are callable expressions: self.switchTab = { 'N': self.handleN, 'M': self.handleM, ... } Where self.handleN, etc., are methods on the current class. The actual switch looks like this: self.switchTab[selector]() According to some profiling I've done with cProfile (and Python 2.5.2) this is actually a little bit faster than a chain of if..elif... statements. My question is, do folks think this is a reasonable choice? I can't imagine that re-framing this in terms of objects and polymorphism would be as fast, and I think the code looks reasonably clear to a reader.

• What is the best strategy for populating a TableView from a service?

  - by alrutherford

  I have an application which has a potentially long running background process. I want this process to populate a TableView as results objects are generated. The results objects are added to an observableList and have properties which are bound to the columns in the usual fashion for JavaFX. As an example of this consider the following sample code Main Application import java.util.LinkedList; import javafx.application.Application; import javafx.collections.FXCollections; import javafx.collections.ObservableList; import javafx.event.ActionEvent; import javafx.event.EventHandler; import javafx.geometry.Insets; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.control.TableColumn; import javafx.scene.control.TableView; import javafx.scene.control.cell.PropertyValueFactory; import javafx.scene.layout.VBox; import javafx.stage.Stage; public class DataViewTest extends Application { private TableView<ServiceResult> dataTable = new TableView<ServiceResult>(); private ObservableList<ServiceResult> observableList; private ResultService resultService; public static void main(String[] args) { launch(args); } @Override public void start(Stage stage) { observableList = FXCollections.observableArrayList(new LinkedList<ServiceResult>()); resultService = new ResultService(observableList); Button refreshBtn = new Button("Update"); refreshBtn.setOnAction(new EventHandler<ActionEvent>() { @Override public void handle(ActionEvent arg0) { observableList.clear(); resultService.reset(); resultService.start(); } }); TableColumn<ServiceResult, String> nameCol = new TableColumn<ServiceResult, String>("Value"); nameCol.setCellValueFactory(new PropertyValueFactory<ServiceResult, String>("value")); nameCol.setPrefWidth(200); dataTable.getColumns().setAll(nameCol); // productTable.getItems().addAll(products); dataTable.setItems(observableList); Scene scene = new Scene(new Group()); stage.setTitle("Table View Sample"); stage.setWidth(300); stage.setHeight(500); final VBox vbox = new VBox(); vbox.setSpacing(5); vbox.setPadding(new Insets(10, 0, 0, 10)); vbox.getChildren().addAll(refreshBtn, dataTable); ((Group) scene.getRoot()).getChildren().addAll(vbox); stage.setScene(scene); stage.show(); } } Service public class ResultService extends Service<Void> { public static final int ITEM_COUNT = 100; private ObservableList<ServiceResult> observableList; /** * Construct service. * */ public ResultService(ObservableList<ServiceResult> observableList) { this.observableList = observableList; } @Override protected Task<Void> createTask() { return new Task<Void>() { @Override protected Void call() throws Exception { process(); return null; } }; } public void process() { for (int i = 0; i < ITEM_COUNT; i++) { observableList.add(new ServiceResult(i)); } } } Data public class ServiceResult { private IntegerProperty valueProperty; /** * Construct property object. * */ public ServiceResult(int value) { valueProperty = new SimpleIntegerProperty(); setValue(value); } public int getValue() { return valueProperty.get(); } public void setValue(int value) { this.valueProperty.set(value); } public IntegerProperty valueProperty() { return valueProperty; } } Both the service and the TableView share a reference to the observable list? Is this good practise in JavaFx and if not what is the correct strategy? If you hit the the 'Update' button the list will not always refresh to the ITEM_COUNT length. I believe this is because the observableList.clear() is interfering with the update which is running in the background thread. Can anyone shed some light on this?
