• Homework - C# - Creating an object instance with a button click

  - by Erica

  I'm new to learning Windows Programming with C#. My current assignment is to create a very simple bank account program: The user enters the accountholder name, account number and beginning balance, then presses a "Continue" button to work with that account by making deposits and withdrawals. I wrote a separate "BankAccount" class with the required data members and methods. I've put the code for the creation of the BankAccount object in the Continue button click event BankAccount currentAccount = new BankAccount(acctName, acctNum, beginningBalance); But that seems to make it local to that method only, and currentAccount is not recognized when I'm programming the click event for the "Record Transactions" (deposits and withdrawals) button. How and where should the creation of the BankAccount object be coded in order for it to be created when the "Continue" button is clicked and also recognized in the "Record Transactions" button click event? Please let me know if any clarification is needed, or if you need to see part or all of my code.

• How to find Junit tests that are using a given Java method directly or indirectly

  - by IT-Worx

  Assume there are Java project and Junit project in an Eclipse workspace. And All the unit tests are located in the Junit project and dependent on the application Java project. When making changes to a Java method, I need to find the unit tests that are using the method directly or indirectly, so that I can run the corresponding tests locally in my PC before checking into source control. I don't want to run the entire junit project since it takes time. I could use Eclipse call hierarchy to expand caller methods one by one until I find a test method. But for a project including more than 1 million lines of source code, digging down the call hierarchy takes time too. The search scope within call hierarchy view doesn't seem help much. Appreciate any help.

• How do you extract data from a Date/Time widget from a C++ MFC dialog in VS2008

  - by jkerian

  This is a fairly basic question, but I haven't been able to find any from-to guides from VS6-VS2008. I have a dialog box that contains controls of various types, I've discovered the way of auto-generating OnBnClickedMyFooBarButtonHere() methods via the Properties dialog on the dialog editor. I can also use CWnd::GetDlgItemText(int ,CString &) to extract text, and the oddly paramaterized GetDlgItemInt(int, bool*, bool) to extract signed integers, but is there really no other option for a Date or Time value other than Manually adding in all the DDX_ crap that the class wizard used to do in VS6 Using GetDlgItemText and then parsing whatever it gives me?

• Getting All categories in external page.

  - by Harsha

  This is very basic magento question i guess. I want to first get all the store categories, then loop through them to get their sub-categories and products and similarly continue till the last sub-category. I will be using this in an external page having Mage::app() declared at the top of the page. I am not aware of the Magento API's(if thats wat they are called) to use to get this functionality. Remember I am not using this in any of the templates, so something like getCurrentCategory() will not work here i guess. Also please guide if there are any good resources to search for particular functionality in magento and API's to implement it, or am i doomed to go through their phpdoc to know the list of methods. Any help here will be greatly appreciated, Thanks.

• Fragment savedInstanceState is always null (Android support lib)

  - by Evgeny Egorov

  I wrote a simple test project, but I cant understand why I always receive savedInstanceState = null in lifecycle methods onCreate, onCreateView and onActivityCreated. I change the screen orientation, see the log, but state not saved. Tell me please where is my mistake. Thanks. The code of fragment class is: public class TestFragment extends Fragment { private String state = "1"; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { if (savedInstanceState != null) { //never works state = savedInstanceState.getString("state"); } //always prints 1 Toast.makeText(getActivity(), state, Toast.LENGTH_SHORT).show(); return inflater.inflate(R.layout.fragment_layout, container, false); } @Override public void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); outState.putString("state", "2"); Log.e("", "saved 2"); } }

• How to crete a Java Iterator that throws IOException

  - by Antonio

  I'd like to implement an iterator that retrieves objects from disk/network. Iterator itr = getRemoteIterator(); while(itr.hasNext()) { Object element = itr.next(); System.out.print(element + " "); } However the problem is that hasNext() and next() methods of the Iterator object does not allow to throw IOException. Is there any other standard interface work around this issue? Desired code is: public interface RemoteIterator<E> { boolean hasNext() throws IOException; E next() throws IOException; void remove(); }

• So where is this calling super?

  - by dontWatchMyProfile

  From the Core Data docs: Inheritance If you have two subclasses of NSManagedObject where the parent class implements a dynamic property and its subclass (the grandchild of NSManagedObject) overrides the methods for the property, those overrides cannot call super. @interface Parent : NSManagedObject @property(nonatomic, retain) NSString* parentString; @end @implementation Parent @dynamic parentString; @end @interface Child : Parent @end @implementation Child - (NSString *)parentString { // this throws a "selector not found" exception return parentString.foo; } @end very, very funny, because: I see nobody calling super. Or are they? Wait... parentString.foo results in ... a crash ??? it's a string. How can that thing have a .foo suffixed to it? Just another documentation bug?

• Can we change <input type="file"> style?

  - by learner.php

  I tried to change the HTML form, input type file. Here is my code: HTML, form id = form <input class="upload_file" type="file" id="file" name="file" /> .CSS I tried both: .upload_button{ background: url('../images/upload_btn_bg.png') no-repeat; width: 200px; height: 40px; } #form input[type=file]{ background: url('../images/upload_btn_bg.png') no-repeat; width: 200px; height: 40px; } None of both of those methods works. I did see from some website, like facebook, youtube, google or twitter, they have different style. Wonder how they do it.

• send() always interrupted by EPIPE

  - by Manuel Abeledo

  I've this weird behaviour in a multithreaded server programmed in C under GNU/Linux. While it's sending data, eventually will be interrupted by SIGPIPE. I managed to ignore signals in send() and treat errno after each action because of it. So, it has two individual sending methods, one that sends a large amount of data at once (or at least tries to), and another that sends a nearly similar amount and slices it in little chunks. Finally, I tried with this to keep it sending data. do { total_bytes_sent += send(client_sd, output_buf + total_bytes_sent, output_buf_len - total_bytes_sent, MSG_NOSIGNAL); } while ((total_bytes_sent < output_buf_len) && (errno != EPIPE)); This ugly piece of code does its work in certain situations, but not always. I'm pretty sure it's not a hardware or ISP problem, as this server is running in six european servers, four in Germany and two in France. Any ideas? Thanks in advance.

• ActiveX Deployment

  - by balexandre

  We have used for 8 years an ActiveX builder in Delphi and we are now using it on Internet Explorer over the internet (and not on local machine as it was always been the process until here) As today we use this object in the HTML: <object id="ActiveX" classid="CLSID:8EC68701-329D-4567-BCB5-9EE4BA43D358" width="14" height="14"> <param name="tabName" value="AccountPlan"> </object> My question is, what are the viable methods to deploy an Active X Control over HTTP/S, what parameters should I need to append to tell where to find it (http url) and download a new one if newer is available? I got into this article from MSDN Library but refers to VB5.0 and it's dated 1997 ... Just wanna know what can I do now, as probably the tools evolved since last century All help is appreciated, Thank you.

• what's the best (most effecient) way in asp .net to return a whole page into tabbed content?

  - by ijjo

  what i want to do is every time i click on a tab, the content area is replaced by pretty much a whole new page. i don't want a full page load so i want to do it in ajax, but i'm used to sending back small jason data via page methods. i'm not sure how i would construct a whole new page and return that via ajax and i would like to simply assign the whole content returned to a div and be done with it. what's the best way to do this with the least amount of overhead (i know there are some inefficient ways the scriptmanager does ajax)? or is it better to load the tabbed content in an iframe? fyi i'm already using jquery to call lightweight pagemethods on my asp net page and that works great.

• How to store data to Excel from DataSet without going cell-by-cell?

  - by Jason Barnwell

  Duplicate of: What’s the simplest way to import a System.Data.DataSet into Excel? Using c# under VS2008, we can create an excel app, workbook, and then worksheet fine by doing this: Application excelApp = new Application(); Workbook excelWb = excelApp.Workbooks.Add(template); Worksheet excelWs = (Worksheet)this.Application.ActiveSheet; Then we can access each cell by "excelWs.Cells[i,j]" and write/save without problems. However with large numbers of rows/columns, we are expecting a loss in efficiency. Is there a way to "data bind" from a DataSet object into the worksheet without using the cell-by-cell approach? Most of the methods we have seen at some point revert to the cell-by-cell approach. Thanks for any suggestions.

• Programmatically Untag FB Photos with Javascript

  - by Tal

  Hello! I've spent the past hour hacking away at this: I want to write a Javscript routine to programatically untag myself from photos on Facebook. Once it works, I'll run it in the Firebug console and untag myself from all Facebook photos (there's no way to do this through the GUI). I wanted to see if you guys had some advice to get me on my journey. I have a few methods in mind but haven't come too far along quite yet. I've tried an AJAX approach by creating a new HTML request and pointing it to the remove_tag URL, which looks something like this: /ajax/photo_tagging_ajax.php?pid=(PICTURE_ID)&id=(PICTURE_OWNER_ID)&subject=(SOMETHING)&name=(YOUR+NAME)&action=remove Not surprisingly, this doesn't work (yet). I've been checking the HTTP response in Firebug and it's quite different than the one when I actually untag a picture. It's not even sending a POST request. Will this even be possible or am I dreaming? (it's almost 4AM)

• Does Core Data automatically validate new values when they are set?

  - by mystify

  In this question, someone asked how to write a validation method for Core Data. I did that, and it looks cool. But one thing doesn't happen: The validation. I can easily set any "bad" value and this method doesn't get called automatically. What's the concept behind this? Must I always first call the validation method before setting any value? So would I write setter methods which call the appropriate validation method first? And if yes, what's the point of following a strict convention in how to write the validation method signature? I guess there's also some automatic way of validation, then. How to activate this?

• StructureMap: How can i unit test the registry class?

  - by Marius

  I have a registry class like this: public class StructureMapRegistry : Registry { public StructureMapRegistry() { For<IDateTimeProvider>().Singleton().Use<DateTimeProviderReturningDateTimeNow>(); } I want to test that the configuration is according to my intent, so i start writing a test: public class WhenConfiguringIOCContainer : Scenario { private TfsTimeMachine.Domain.StructureMapRegistry registry; private Container container; protected override void Given() { registry = new TfsTimeMachine.Domain.StructureMapRegistry(); container = new Container(); } protected override void When() { container.Configure(i => i.AddRegistry(registry)); } [Then] public void DateTimeProviderIsRegisteredAsSingleton() { // I want to say "verify that the container contains the expected type and that the expected type // is registered as a singleton } } How can verify that the registry is accoring to my expectations? Note: I introduced the container because I didn't see any sort of verification methods available on the Registry class. Idealy, I want to test on the registry class directly.

• Kepping object in memory (iPhone SDK)

  - by Chris

  I am trying to create a UIImageView called theImageView in the touchesBegan method that I can then then move to a new location in touchesMoved. Currently I am receiving an "undeclared" error in touchesMoved where I set the new location for theImageView. What can I do to keep theImageView in memory between these two methods? - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { ... UIImageView *theImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]]; theImageView.frame = CGRectMake(263, 228, 193, 300); [theImageView retain]; ... } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { ... theImageView.frame = CGRectMake(300, 300, 193, 300); ... }

• Any good class diagram editors out there for Java (not UML)

  - by user85116

  I'm looking for an editor that can create class diagrams, similar to the typical UML class diagram, but specifically for java (so using java terminology; instead of terms like "generalization, realization etc", we use the java equivalents "interface, abstract class, extends etc"). I've looked into UML several times, but each time I've been turned off by the shear amount of "stuff" that comes with UML. I just want to be able to model my java classes quickly and intuitively, without getting bogged down by all the cruft that comes with UML. Preferably, it would come with a source reader that can keep the diagram up to date, and with a few nice features like "show only public methods in this class" etc. As well, it would automatically "know" about the classes in the standard java library, and possibly even be able to read classes from jars. Performance is also a big thing for me, I don't like having to wait 2 seconds for a popup menu to appear, or watch the diagram jerk crazily while resizing an element in the model. What do you think, am I asking too much?

• Java: How to get Unicode name of a character (or its type category)?

  - by java.is.for.desktop

  Hello, everyone! The Character class in Java defines methods which check a given char argument for equality with certain Unicode chars or for belonging to some type category. These chars and type categories are named. As stated in given javadoc, examples for named chars are HORIZONTAL TABULATION, FORM FEED, ...; example for named type categories are SPACE_SEPARATOR, PARAGRAPH_SEPARATOR, ... However, being byte or int values instead of enums, the name of these types are "hidden" at runtime. So, is there a possibility to get characters' and/or type categories' names at runtime?

• Why I should use an N-Tier Approach When using an SqlDatasource is ALOT EASIER ?

  - by The_AlienCoder

  When it comes to web development I have always tried to work SMART not HARD. So for along time My Aproach to interacting with databases in my AspNet projects has been this : 1) Create my stored procedures 2) Drag an SQLDatasource control on my aspx page 3) Bind a DataList Control to my SQLDatasource 4) Insert, Update & Delete by using my Datalist or programmatically using built in SQLDatasource methods e.g MySqlDataSource.InsertParameters["author"].DefaultValue = TextBox1.Text; MySqlDataSource.Insert(); Recently however I got a relatively easy web project. So I decided to employ a 3-tier Model...But I got exhausted halfway and just didnt seem worth it ! It seemed like I was working too HARD for a project that could have been easily accomplished by a couple of SqlDataSource Controls. So Why Is the N-Tier Model better than my Approach? Has it anything to do with performance? What are the advantages of the ObjectDataSource control over the SqlDataSource Control?

• how to interpret testng console log message for passing tests?

  I ran testng tests for my test classes, I get the following three types of log output when I run the passing tests. I am using org.testng.AssertJUnit.assertTrue() methods in my tests. [testng] PASSED: testMethod1 on null(test.foo.bar.Class1) [testng] PASSED: testMethod2 on Default test name(test.foo.bar.jar.Class2) [testng] PASSED: testMethod3 Can any one please tell me why for some tests it says "on null" for some it says "on Default test name ... " and for some it does not say anything on the console output. Specifically I want to make it consistent message. Environment : linux Testng framework : 6.3.2beta please advise. thanks.

• Can you use Javascript to detect a file download window created server side?

  - by Zacho

  I have a jQuery plugin I use to dynamically create and render a form on a default.aspx asp.net page, then submit it. The page it gets submitted to is a pdf.aspx page. The page builds a PDF then uses Response.Write to write the file (application/pdf) to the browser. I use the same method to render XLSX files to the browser as well. It works really great, but I need a callback or some event to tell the button when to stop spinning. This prevents the user from continuously clicking the Excel or PDF buttons. Does anyone know a way to detect the file dialog window when it was not created using javascript? I am also open to other methods of callback from the server side as well.

• What is the difference between the * and the & operators in c programming?

  - by Wesley

  I am just making sure I understand this concept correctly. With the * operator, I make a new variable, which is allocated a place in memory. So as to not unnecessarily duplicate variables and their values, the & operator is used in passing values to methods and such and it actually points to the original instance of the variable, as opposed to making new copies...Is that right? It is obviously a shallow understanding, but I just want to make sure I am not getting them mixed up. Thanks!

• Is it possible to use Data Annotations to validate parameters passed to an Action method of a Contro

  - by dannie.f

  I am using Data Annotations to validate my Model in ASP.NET MVC. This works well for action methods that has complex parameters e.g, public class Params { [Required] string Param1 {get; set;} [StringLength(50)] string Param2 {get; set;} } ActionResult MyAction(Params params) { If(ModeState.IsValid) { // Do Something } } What if I want to pass a single string to an Action Method (like below). Is there a way to use Data Annotations or will I have to wrap the string into a class? ActionResult MyAction(string param1, string param2) { If(ModeState.IsValid) { // Do Something } }
