Have to click twice to submit the form

- by phil

Intended function: require user to select an option from the drop down menu. After user clicks submit button, validate if an option is selected. Display error message and not submit the form if user fails to select. Otherwise submit the form. Problem: After select an option, button has to be clicked twice to submit the form. I have no clue at all.. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <script src="jquery-1.4.2.min.js" type="text/javascript"></script> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <style> p{display: none;} </style> </head> <script> $(function(){ // language as an array var language=['Arabic','Cantonese','Chinese','English','French','German','Greek','Hebrew','Hindi','Italian','Japanese','Korean','Malay','Polish','Portuguese','Russian','Spanish','Thai','Turkish','Urdu','Vietnamese']; $('#muyu').append('<option value=0>Select</option>'); //loop through array for (i in language) //js unique statement for iterate array { $('#muyu').append($('<option>',{id:'muyu'+i,val:language[i], html:language[i]})) } $('form').submit(function(){ alert('I am being called!'); // check if submit event is triggered if ( $('#muyu').val()==0 ) {$('#muyu_error').show(); } else {$('#muyu_error').hide(); return true;} return false; }) }) </script> <form method="post" action="match.php"> I am fluent in <select name='muyu' id='muyu'></select> <p id='muyu_error'>Tell us your native language</p> <input type="submit" value="Go"> </form>

How to cancel a jquery.load()?

- by Dirk Jönsson

I'd like to cancel a .load() operation, when the load() does not return in 5 seconds. If it's so I show an error message like 'sorry, no picture loaded'. What I have is... ...the timeout handling: jQuery.fn.idle = function(time, postFunction){ var i = $(this); i.queue(function(){ setTimeout(function(){ i.dequeue(); postFunction(); }, time); }); return $(this); }; ... initializing of the error message timeout: var hasImage = false; $('#errorMessage') .idle(5000, function() { if(!hasImage) { // 1. cancel .load() // 2. show error message } }); ... the image loading: $('#myImage') .attr('src', '/url/anypath/image.png') .load(function(){ hasImage = true; // do something... }); The only thing I could not figure out is how to cancel the running load() (if it's possible). Please help. Thanks! Edit: Another way: How do I prevent the .load() method to call it's callback function when it's returning?

Address String Split in javscript

- by Arasoi

Ok folks I have bombed around for a few days trying to find a good solution for this one. What I have is two possible address formats. 28 Main St Somecity, NY 12345-6789 or Main St Somecity, Ny 12345-6789 What I need to do Is split both strings down into an array structured as such address[0] = HousNumber address[1] = Street address[2] = City address[3] = State address[4] = ZipCode My major problem is how to account for the lack of a house number. with out having the whole array shift the data up one. address[0] = Street address[1] = City address[2] = State address[3] = ZipCode [Edit] For those that are wondering this is what i am doing atm . (cleaner version) place = response.Placemark[0]; point = new GLatLng(place.Point.coordinates[1],place.Point.coordinates[0]); FCmap.setCenter(point,12); var a = place.address.split(','); var e = a[2].split(" "); var x = a[0].split(" "); var hn = x.filter(function(item,index){ return index == 0; }); var st = x.filter(function(item,index){ return index != 0; }); var street = ''; st.each(function(item,index){street += item + ' ';}); results[0] = new Hash({ FullAddie: place.address, HouseNum: hn[0], Dir: '', Street: street, City: a[1], State: e[1], ZipCode: e[2], GPoint: new GMarker(point), Lat: place.Point.coordinates[1], Lng: place.Point.coordinates[0] }); // End Address Splitting

C++ Header file questions

- by Karl

So I'm trying to learn C++ and I've gotten as far as using header files. They really make no sense to me. I've tried many combinations of this but nothing so far has worked: Main.cpp: #include "test.h" int main() { testClass Player1; return 0; } test.h: #ifndef TEST_H_INCLUDED #define TEST_H_INCLUDED class testClass { private: int health; public: testClass(); ~testClass(); int getHealth(); void setHealth(int inH); }; #endif // TEST_H_INCLUDED test.cpp: #include "test.h" testClass::testClass() { health = 100; } testClass::~testClass() {} int testClass::getHealth() { return(health); } void testClass::setHealth(int inH) { health = inH; } What I'm trying to do is pretty simple, but the way the header files work just makes no sense to me at all. Code blocks returns the following on build: obj\Debug\main.o(.text+0x131)||In function main':| *voip*\test\main.cpp |6|undefined reference totestClass::testClass()'| obj\Debug\main.o(.text+0x13c):voip\test\main.cpp|7|undefined reference to `testClass::~testClass()'| ||=== Build finished: 2 errors, 0 warnings ===| I'd appreciate any help. Or if you have a decent tutorial for it, that would be fine too (most of the tutorials I've googled haven't helped)

Manipulating a NSTextField via AppleScript

- by Garry

A little side project I'm working on is a digital life assistant, much like project JARVIS. What I'm trying to do is speak to my mac, have my words translated to text and then have the text interpreted by my program. Currently, my app is very simple, consisting of a single window containing a single wrapped NSTextView. Using MacSpeech Dictate, When I say the custom command "Jeeves", MacSpeech ensures that my app is frontmost, highlights any text in the TextField and clears it, then presses the Return key to trigger the textDidEndEditing method of NSTextField. This is done via Applescript. MacSpeech then switches to dictation mode and the next sentence I say will appear in the NSTextField. What I can't figure out is how to signify that I have finished saying a command to my program. I could simply say another keyword like "execute" or something similar that would send an AppleScript return keystroke to my app (thereby triggering the textDidEndEditing event) but this is cumbersome. Is there a notification that happens when text is pasted into a NSTextField? Would a timer work that would fire after maybe three seconds once my program becomes frontmost (three seconds should be sufficient for me to say a command)? Thanks,

[C++][Boost] Acceptor and Problems with Async_Accept

- by bobber205

See code. :P I am able to receive new connections before async_accept() has been called. My delegate function is also never called so I can't manage any connections I receive, rendering the new connections useless. ;) So here's my question. Is there a way to prevent the Boost ASIO acceptor from getting new connections on its own and only getting connections from async_accept()? Thanks! bool AlexSocket::StartListening(int port) { bool didStart = false; if (!this->listening) { //try to listen acceptor = new tcp::acceptor(this->myService); boost::asio::ip::tcp::endpoint endpoint(boost::asio::ip::tcp::v4(), port); acceptor->open(endpoint.protocol()); acceptor->set_option(boost::asio::ip::tcp::acceptor::reuse_address(true)); acceptor->bind(endpoint); //CAN GET NEW CONNECTIONS HERE (before async_accept is called) acceptor->listen(); didStart = true; //probably change? tcp::socket* tempNewSocket = new tcp::socket(this->myService); acceptor->async_accept(*tempNewSocket, boost::bind(&AlexSocket::NewConnection, this, tempNewSocket, boost::asio::placeholders::error) ); } else //already started! return false; this->listening = didStart; return didStart; } //this function is never called :( void AlexSocket::NewConnection(tcp::socket* s, const boost::system::error_code& error) { cout << "New Connection Made" << endl; //Start new accept async tcp::socket* tempNewSocket = new tcp::socket(this->myService); acceptor->async_accept(*tempNewSocket, boost::bind(&AlexSocket::NewConnection, this, tempNewSocket, boost::asio::placeholders::error) ); }

Where to define a filter function for a form field in my Joomla component's preferences

- by Herman

I am creating a component in Joomla 2.5. This component has some options that are defined in its config.xml, so they can be set in the preferences of the component. Now I would like to apply a filter to one of these option fields, using the attribute filter="my_filter". In the source code of JForm I saw the following lines at the very end of the implementation of JForm::filterField(): if (strpos($filter, '::') !== false && is_callable(explode('::', $filter))) { $return = call_user_func(explode('::', $filter), $value); } elseif (function_exists($filter)) { $return = call_user_func($filter, $value); } That's what I needed for using a filter function defined by myself! I managed to do this for form fields used in the views of my component. I defined the filter function as MyComponentHelper::my_filter(), where MyComponentHelper is a helper class which I always load in the very base of my component. And in the form's xml I added filter="MyComponentHelper::my_filter" to the fields that have to be filtered. However... when I am trying to apply the filter function to a form field in my component's preferences, I am not in my own component, but in com_config instead, so my helper class is not available! So, therefore, my question: where to define my own filter function in such a way that it can be found and called by JForm::filterField() in com_config?? Help is very much appreciated.

Retrieve class name hierarchy as string

- by Jeff Wain

Our system complexity has risen to the point that we need to make permission names tied to the client from the database more specific. In the client, permissions are referenced from a static class since a lot of client functionality is dependent on the permissions each user has and the roles have a ton of variety. I've referenced this post as an example, but I'm looking for a more specific use case. Take for instance this reference, where PermissionAlpha would be a const string: return HasPermission(PermissionNames.PermissionAlpha); Which is great, except now that things are growing more complex the classes are being structured like this: public static class PermissionNames { public static class PermissionAlpha { public const string SubPermission; } } I'm trying to find an easy way to reference PermissionAlpha in this new setup that will act similar to the first declaration above. Would the only way to do this be to resort to pulling the value of the class name like in the example below? I'm trying to keep all the names in one place that can be reference anywhere in the application. public static class PermissionAlpha { public static string Name { get { return typeof(PermissionAlpha).Name; } } }

Validate a XDocument against schema without the ValidationEventHandler (for use in a HTTP handler)

- by Vaibhav Garg

Hi everyone, (I am new to Schema validation) Regarding the following method, System.Xml.Schema.Extensions.Validate( ByVal source As System.Xml.Linq.XDocument, ByVal schemas As System.Xml.Schema.XmlSchemaSet, ByVal validationEventHandler As System.Xml.Schema.ValidationEventHandler, ByVal addSchemaInfo As Boolean) I am using it as follows inside a IHttpHandler - Try Dim xsd As XmlReader = XmlReader.Create(context.Server.MapPath("~/App_Data/MySchema.xsd")) Dim schemas As New XmlSchemaSet() : schemas.Add("myNameSpace", xsd) : xsd.Close() myXDoxumentOdj.Validate(schemas, Function(s As Object, e As ValidationEventArgs) SchemaError(s, e, context), True) Catch ex1 As Threading.ThreadAbortException 'manage schema error' Return Catch ex As Exception 'manage other errors' End Try The handler- Function SchemaError(ByVal s As Object, ByVal e As ValidationEventArgs, ByVal c As HttpContext) As Object If c Is Nothing Then c = HttpContext.Current If c IsNot Nothing Then HttpContext.Current.Response.Write(e.Message) HttpContext.Current.Response.End() End If Return New Object() End Function This is working fine for me at present but looks very weak. I do get errors when I feed it bad XML. But i want to implement it in a more elegant way. This looks like it would break for large XML etc. Is there some way to validate without the handler so that I get the document validated in one go and then deal with errors? To me it looks Async such that the call to Validate() would pass and some non deterministic time later the handler would get called with the result/errors. Is that right? Thanks and sorry for any goofy mistakes :).

Strange JPA one-to-many behavior when trying to set the "many" on the "one" entity

- by errr

I've mapped two entities using JPA (specifically Hibernate). Those entities have a one-to-many relationship (I've simplified for presentation): @Entity public class A { @ManyToOne public B getB() { return b; } } @Entity public Class B { @OneToMany(mappedBy="b") public Set<A> getAs() { return as; } } Now, I'm trying to create a relationship between two instances of these entities by using the setter of the one-side/not-owner-side of the relationship (i.e the table being referenced to): em.getTransaction().begin(); A a = new A(); B b = new B(); Set<A> as = new HashSet<A>(); as.add(a); b.setAs(as); em.persist(a); em.persist(b); em.getTransaction().commit(); But then, the relationship isn't persisted to the DB (the row created for entity A isn't referencing the row created for entity B). Why is it so? I'd excpect it to work. Also, if I remove the "mappedBy" property from the @OneToMany annotation it will work. Again - why is it so? and what are the possible effects for removing the "mappedBy" property?

Adding array to an object breaks the array

- by DisgruntledGoat

I have an array like this (output from print_r): Array ( [price] => 700.00 [room_prices] => Array ( [0] => [1] => [2] => [3] => [4] => ) [bills] => Array ( [0] => Gas ) ) I'm running a custom function to convert it to an object. Only the top-level should be converted, the sub-arrays should stay as arrays. The output comes out like this: stdClass Object ( [price] => 700.00 [room_prices] => Array ( [0] => Array ) [bills] => Array ( [0] => Array ) ) Here is my conversion function. All it does is set the value of each array member to an object: function array_to_object( $arr ) { $obj = new stdClass; if ( count($arr) == 0 ) return $obj; foreach ( $arr as $k=>$v ) $obj->$k = $v; return $obj; } I can't figure this out for the life of me!

Asp MVC - "The Id field is required" validation message on Create; Id not set to [Required]

- by Dann

This is happening when I try to create the entity using a Create style action in Asp.Net MVC 2. The POCO has the following properties: public int Id {get;set;} [Required] public string Message {get; set} On the creation of the entity, the Id is set automatically, so there is no need for it on the Create action. The ModelState says that "The Id field is required", but I haven't set that to be so. Is there something automatic going on here? EDIT - Reason Revealed The reason for the issue is answered by Brad Wilson via Paul Speranza in one of the comments below where he says (cheers Paul): You're providing a value for ID, you just didn't know you were. It's in the route data of the default route ("{controller}/{action}/{id}"), and its default value is the empty string, which isn't valid for an int. Use the [Bind] attribute on your action parameter to exclude ID. My default route was: new { controller = "Customer", action = "Edit", id = " " } // Parameter defaults EDIT - Update Model technique I actually changed the way I did this again by using TryUpdateModel and the exclude parameter array asscoiated with that. [HttpPost] public ActionResult Add(Venue collection) { Venue venue = new Venue(); if (TryUpdateModel(venue, null, null, new[] { "Id" })) { _service.Add(venue); return RedirectToAction("Index", "Manage"); } return View(collection); }

Serialization in C#

- by anjansaha

My class structure is as follows. [Serializable] [XmlRootAttribute("person", Namespace = "", IsNullable = false)] public class Person : IDisposable { Private int _id; Private string _name; [XmlElement(“id”)] Public int Id { Get{ return _id;} Set{ _id = value;} } [XmlElement(“name”)] Public string Name { Get{return _name;} Set{_name = value;} } } I am getting the following xml when I serialize the above class <person> <id>1</id> <name>Test</name> </person> Now, I would like to serialize the above class as follows i.e. I would like append “type” attribute for each public property that is serialized as xml element. I can append “type” attribute to “person” node by declaring another public property “type” with “[XmlAttribute(“type”)]” but I would like to achieve the same for each public property that is serialized as xml element. Any idea to achieve below: <person type=”Person”> <id type=”int”>1</id> <name type=”string”>Test</name> </person>

Why is the exception thrown on memcpy using during copying LPBYTE to LPTSTR (clipboard)?

- by user46503

Hello, I have a LPBYTE array (taken from file) and I need to copy it into LPTSRT (actually into the clipboard). The trouble is copying work but unstable, sometime an exception was thrown (not always) and I don't understand why. The code is: FILE *fConnect = _wfopen(connectFilePath, _T("rb")); if (!fConnect) return; fseek(fConnect, 0, SEEK_END); lSize = ftell(fConnect); rewind(fConnect); LPBYTE lpByte = (LPBYTE) malloc(lSize); fread(lpByte, 1, lSize, fConnect); lpByte[lSize] = 0; fclose(fConnect); //Copy into clipboard BOOL openRes = OpenClipboard(NULL); if (!openRes) return; DWORD err = GetLastError(); EmptyClipboard(); HGLOBAL hText; hText = GlobalAlloc(GMEM_MOVEABLE, (lSize+ sizeof(TCHAR))); LPTSTR sMem = (TCHAR*)GlobalLock(hText); memcpy(sMem, lpByte, (lSize + sizeof(TCHAR))); The last string is the place where the exception is thrown. Thanks a lot

Update data table on ASMX Service side

- by Paul

Hi, I need advice. On Web Service side a I hav this method : public DataSet GetDs(string id) { SqlConnection conn = null; SqlDataAdapter da = null; DataSet ds; try { string sql = "SELECT * FROM Tab1"; string connStr = WebConfigurationManager.ConnectionStrings["Employees"].ConnectionString; conn = new SqlConnection(connStr); conn.Open(); da = new SqlDataAdapter(sql, conn); ds = new DataSet(); da.Fill(ds, "Tab1"); return ds; } catch (Exception ex) { throw ex; } finally { if (conn != null) conn.Close(); if (da != null) da.Dispose(); } } It return dataset to client app. I client application is dataset binding in datagridview. Client can insert,update,delete row from table. If client finish his work, I want accept change in data table on web service side. I can sent clients all dataset na update table on web service side, but I want sent only changed data. Any advice? Thank u.

SSRS code variable resetting on new page

- by edmicman

In SSRS 2008 I am trying to maintain a SUM of SUMs on a group using custom Code. The reason is that I have a table of data, grouped and returning SUMs of the data. I have a filter on the group to remove lines where group sums are zero. Everything works except I'm running into problems with the group totals - it should be summing the visible group totals but is instead summing the entire dataset. There's tons of articles about how to work around this, usually using custom code. I've made custom functions and variables to maintain a counter: Public Dim GroupMedTotal as Integer Public Dim GrandMedTotal as Integer Public Function CalcMedTotal(ThisValue as Integer) as Integer GroupMedTotal = GroupMedTotal + ThisValue GrandMedTotal = GrandMedTotal + ThisValue Return ThisValue End Function Public Function ReturnMedSubtotal() as Integer Dim ThisValue as Integer = GroupMedTotal GroupMedTotal = 0 Return ThisValue End Function Basically CalcMedTotal is fed a SUM of a group, and maintains a running total of that sum. Then in the group total line I output ReturnMedSubtotal which is supposed to give me the accumulated total and reset it for the next group. This actually works great, EXCEPT - it is resetting the GroupMedTotal value on each page break. I don't have page breaks explicitly set, it's just the natural break in the SSRS viewer. And if I export the results to Excel everything works and looks correctly. If I output Code.GroupMedTotal on each group row, I see it count correctly, and then if a group spans multiple pages on the next page GroupMedTotal is reset and begins counting from zero again. Any help in what's going on or how to work around this? Thanks!

Entity Framework and WCf

- by Nihilist

Hi I am little confused on designing WCf services with EF. When using WCf and EF, where do we draw this line on what properties to return and what not to with the entity. Here is my scenario I have User. Here are the relations. User [1 to many] Address, User [ 1 to many] Email, User [ 1 to many] Phone So now on the webform, on page1 I can edit user information. say I can edit few properties on the user entity and can also edit address, phone, email entities[ like add / delete and update any] On page2, i can only update user properties and nothing related to navigation properties [ address, email, phone]. So when I return the User Entity [ OR DTO] should i be returning the navigation properties too? Or should the client make multiple calls to get navigation properites. Also, how does it go with Save? Like should the client make multiple calls to save user and related entites or just one call to save the graph? Lets say, if I just have a Save(User user) [ where user has all the related entities too] both page1 and page2 will call save and pass me the user. but one page1 i will need a lot more information. but on page2 i just need the user primitive properties. So my question is, where do we draw this line, how do we design theses services ? Is the WCF operation designed on the page and the fields it has ? I am hoping i explained my problem well enough.

INSERT INTO table doesn't work???

- by Joann

I found a tutorial from nettuts and it has a source code in it so tried implementing it in my site.. It is working now. However, it doesn't have a Registration system so I am making one. The thing is, as I have expected, my code is not working... It doesn't seem to know how to INSERT into the database. Here's the function that inserts data into the db. function register_User($un, $email, $pwd) { $query = "INSERT INTO users( username, password, email ) VALUES(:uname, :pwd, :email) LIMIT 1"; if($stmt = $this->conn->prepare($query)) { $stmt->bind_param(':uname', $un); $stmt->bind_param(':pwd', $pwd); $stmt->bind_param(':email', $email); $stmt->execute(); if($stmt->fetch()) { $stmt->close(); return true; } else return "The username or email you entered is already in use..."; } } I have debugged the connection to the database from within the class, it says it's connected. I tried using this method instead: function register($un, $email, $pwd) { $registerquery = $this->conn->query( "INSERT INTO users(uername, password, email) VALUES('".$un."', '".$pwd."', '".$email."')"); if($registerquery) { echo "<h4>Success</h4>"; } else { echo "<h4>Error</h4>"; } } And it echos "Error"... Can you please help me pen point the error in this??? :(

PHP OOP: Avoid Singleton/Static Methods in Domain Model Pattern

- by sunwukung

I understand the importance of Dependency Injection and its role in Unit testing, which is why the following issue is giving me pause: One area where I struggle not to use the Singleton is the Identity Map/Unit of Work pattern (Which keeps tabs on Domain Object state). //Not actual code, but it should demonstrate the point class Monitor{//singleton construction omitted for brevity static $members = array();//keeps record of all objects static $dirty = array();//keeps record of all modified objects static $clean = array();//keeps record of all clean objects } class Mapper{//queries database, maps values to object fields public function find($id){ if(isset(Monitor::members[$id]){ return Monitor::members[$id]; } $values = $this->selectStmt($id); //field mapping process omitted for brevity $Object = new Object($values); Monitor::new[$id]=$Object return $Object; } $User = $UserMapper->find(1);//domain object is registered in Id Map $User->changePropertyX();//object is marked "dirty" in UoW // at this point, I can save by passing the Domain Object back to the Mapper $UserMapper->save($User);//object is marked clean in UoW //but a nicer API would be something like this $User->save(); //but if I want to do this - it has to make a call to the mapper/db somehow $User->getBlogPosts(); //or else have to generate specific collection/object graphing methods in the mapper $UserPosts = $UserMapper->getBlogPosts(); $User->setPosts($UserPosts); Any advice on how you might handle this situation? I would be loathe to pass/generate instances of the mapper/database access into the Domain Object itself to satisfy DI - At the same time, avoiding that results in lots of calls within the Domain Object to external static methods. Although I guess if I want "save" to be part of its behaviour then a facility to do so is required in its construction. Perhaps it's a problem with responsibility, the Domain Object shouldn't be burdened with saving. It's just quite a neat feature from the Active Record pattern - it would be nice to implement it in some way.

ASP.NET GridView "Client-Side Confirmation when Deleting" stopped working on ie - how come?

- by tarnold

A few months ago, I have programmed an ASP.NET GridView with a custom "Delete" LinkButton and Client-Side JavaScript Confirmation according to this msdn article: http://msdn.microsoft.com/en-us/library/bb428868.aspx (published in April 2007) or e.g. http://stackoverflow.com/questions/218733/javascript-before-aspbuttonfield-click The code looks like this: <ItemTemplate> <asp:LinkButton ID="deleteLinkButton" runat="server" Text="Delete" OnCommand="deleteLinkButtonButton_Command" CommandName='<%# Eval("id") %>' OnClientClick='<%# Eval("id", "return confirm(\"Delete Id {0}?\")") %>' /> </ItemTemplate> Surprisingly, "Cancel" doesn't work no more with my ie (Version: 6.0.2900.2180.xpsp_sp2_qfe.080814-1242) - it always deletes the row. With Opera (Version 9.62) it still works as expeced and described in the msdn article. More surprisingly, on a fellow worker's machine with the same ie version, it still works ("Cancel" will not delete the row). The generated code looks like <a onclick="return confirm(...);" href="javascript:__doPostBack('...')"> As confirm(...) returns false on "Cancel", I expect the __doPostBack event in the href not to be fired. Are there any strange ie settings I accidentally might have changed? What else could be the cause of this weird behaviour? Or is this a "please reinstall WinXP" issue?

Create static instances of a class inside said class in Python

- by Samir Talwar

Apologies if I've got the terminology wrong here—I can't think what this particular idiom would be called. I've been trying to create a Python 3 class that statically declares instances of itself inside itself—sort of like an enum would work. Here's a simplified version of the code I wrote: class Test: A = Test("A") B = Test("B") def __init__(self, value): self.value = value def __str__(self): return "Test: " + self.value print(str(Test.A)) print(str(Test.B)) Writing this, I got an exception on line 2 (A = Test("A")). I assume line 3 would also error if it had made it that far. Using __class__ instead of Test gives the same error. File "<stdin>", line 1, in <module> File "<stdin>", line 2, in Test NameError: name 'Test' is not defined Is there any way to refer to the current class in a static context in Python? I could declare these particular variables outside the class or in a separate class, but for clarity's sake, I'd rather not if I can help it. To better demonstrate what I'm trying to do, here's the same example in Java: public class Test { private static final Test A = new Test("A"); private static final Test B = new Test("B"); private final String value; public Test(String value) { this.value = value; } public String toString() { return "Test: " + value; } public static void main(String[] args) { System.out.println(A); System.out.println(B); } } This works as you would expect: it prints: Test: A Test: B How can I do the same thing in Python?

iOS 6 Rotation issue - No rotation from Presented Modal View Controller

- by hart1994

I have a MainViewController which has a button which pushes a new view (InfoViewController), via flip horizontailly. like so: controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; The MainView Controller supports Portrait and PortraitUpsideDown. Like so: - (BOOL)shouldAutorotate { return YES; } - (NSUInteger)supportedInterfaceOrientations { return (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown); } In my InfoViewController it also states the above code. In my AppDelegate it has this in the LaunchOptions: [self.window setRootViewController:self.mainViewController]; In my app.plist file it supports all orientations. This is because other views need to support landscape as well. So On my MainViewController and InfoViewController I need only Portrait and PortraitUpsideDown. But on another view I need all orintations. My MainViewController works fine, but my InfoViewController is working for all orientations. I am having extreme diffulty trying to get this to work in iOS6. I have researched other posts and tried the assistance other people have provided, but had no luck whatsoever. Please can someone help me acheive this thank you. And I'm a Objective-C newbie :p

Class Generics break completely seperate method

- by TheLQ

I found a strange problem when I used class Generics Today: Setting some broke a completely separate method. Here's a small example class that illustrates the problem. This code works just fine public class Sandbox { public interface ListenerManagerTest { public Set<Listener> getListeners(); } public void setListenerManager(ListenerManagerTest listenerManager) { for (Listener curListener : listenerManager.getListeners()) return; } } Now as soon as I use class Generics, the getListeners() method returns Set<Object> instead of Set<Listener> public class Sandbox { public interface ListenerManagerTest<E extends Object> { public Set<Listener> getListeners(); } public void setListenerManager(ListenerManagerTest listenerManager) { for (Listener curListener : listenerManager.getListeners()) //Expected Listener, not Object return; } } What would cause this error? The ##java channel on Freenode said it was because of compile time candy and that I was using a raw type. But how would an raw class type break all generics in the class? And how would of worked before?

GridView does not display correcty sorted Data when i click column

- by user329419

Date column does not display in sorted in GridView using vb.net. In sql server the select query is returning records in sorted manner or in order by. But for some reason GridView does not display properly. it goes to an event preRenderComplete then it binds automatically Protected Sub Page_PreRenderComplete(ByVal sender As Object, ByVal e As
