  • Problem formatting in Eclipse

    - by fastcodejava
    I have a method in Eclipse as below. public String toString() { return "HouseVo [ " + "Name : " + this.name == null ? "" : this.name + "Address : " + this.address == null ? "" : this.address; } When I format it becomes: return "HouseVo [ " + "Name : " + this.name == null ? "" : this.name + "Address : " + this.address == null ? "" : this.address; Any way to fix it so it correctly formats?

  • MySQL join problem

    - by snaken
    Whats wrong with this SQL? It should return results but returns nothing SELECT `pid` FROM `products` LEFT JOIN `prods_to_features` ON (`ptf_pid` = `pid`) WHERE (`ptf_id` = '66' OR `ptf_id` = '67') AND (`ptf_id` = '76') Is it not possible to have the 2nd where clause for the table that has been used in the left join?

  • C++: inheritance problem

    - by Helltone
    It's quite hard to explain what I'm trying to do, I'll try: Imagine a base class A which contains some variables, and a set of classes deriving from A which all implement some method bool test() that operates on the variables inherited from A. class A { protected: int somevar; // ... }; class B : public A { public: bool test() { return (somevar == 42); } }; class C : public A { public: bool test() { return (somevar > 23); } }; // ... more classes deriving from A Now I have an instance of class A and I have set the value of somevar. int main(int, char* []) { A a; a.somevar = 42; Now, I need some kind of container that allows me to iterate over the elements i of this container, calling i::test() in the context of a... that is: std::vector<...> vec; // push B and C into vec, this is pseudo-code vec.push_back(&B); vec.push_back(&C); bool ret = true; for(i = vec.begin(); i != vec.end(); ++i) { // call B::test(), C::test(), setting *this to a ret &= ( a .* (&(*i)::test) )(); } return ret; } How can I do this? I've tried two methods: forcing a cast from B::* to A::*, adapting a pointer to call a method of a type on an object of a different type (works, but seems to be bad); using std::bind + the solution above, ugly hack; changing the signature of bool test() so that it takes an argument of type const A& instead of inheriting from A, I don't really like this solution because somevar must be public.

  • An array problem in C++

    - by manugupt1
    To access the array indice at the xth position we can use some sort of illustration as shown below #include<iostream> using namespace std; int main(){ float i[20]; for(int j=0;j<=20;j++) i[j]=0; } However the following piece of code does not work #include<iostream> using namespace std; float oldrand[55]; int jrand; void advance_random(){ int j1; float new_random; for(j1=0;j1<=23;j1++){ int temp = j1+30; new_random = (oldrand[j1]) - (oldrand[temp]); if(new_random <0.0) new_random = new_random+1; oldrand[j1] = new_random; } for(j1=24;j1<=54;j1++){ new_random[j1] = oldrand[j1] - oldrand[j1-23]; if(new_random[j1]<0.0) new_random[j1] = new_random + 1; oldrand[j1]=new_random; } } I recieve the following error ga.cpp:20: error: invalid types ‘float[int]’ for array subscript ga.cpp:21: error: invalid types ‘float[int]’ for array subscript ga.cpp:22: error: invalid types ‘float[int]’ for array subscript I am not able to find a mistake in my code please help me

  • Flex 4 itemRendererFunction problem.

    - by michael
    This is a Flex 4 application: I have created a list as the following: <s:List id="previewList" horizontalCenter="14" verticalCenter="-112" itemRendererFunction="listItemRendererFunction" click="controller.previewListClickHandler()"> </s:List> And I have the itemRendererFunction: public function listItemRendererFunction(item:Object):ClassFactory { var cla:Class = SimpleItemRenderer; if( item.save == true ) { cla = ColorItemRenderer; } else { cla = SimpleItemRenderer; } return new ClassFactory(cla); } The application works fine if the listItemRendererFunction is inside fx:Script. However, when I put the listItemRendererFunction into a class and change to the following: itemRendererFunction="controller.listItemRendererFunction" in the List component. If I run the application, I get the " Error #1009". Please advice how to fix it.

  • what is the best algorithm to use for this problem

    - by slim
    Equilibrium index of a sequence is an index such that the sum of elements at lower indexes is equal to the sum of elements at higher indexes. For example, in a sequence A: A[0]=-7 A[1]=1 A[2]=5 A[3]=2 A[4]=-4 A[5]=3 A[6]=0 3 is an equilibrium index, because: A[0]+A[1]+A[2]=A[4]+A[5]+A[6] 6 is also an equilibrium index, because: A[0]+A[1]+A[2]+A[3]+A[4]+A[5]=0 (sum of zero elements is zero) 7 is not an equilibrium index, because it is not a valid index of sequence A. If you still have doubts, this is a precise definition: the integer k is an equilibrium index of a sequence if and only if and . Assume the sum of zero elements is equal zero. Write a function int equi(int[] A); that given a sequence, returns its equilibrium index (any) or -1 if no equilibrium indexes exist. Assume that the sequence may be very long.

  • Simple Fluent NHibernate Mapping Problem

    - by user500038
    I have the following tables I need to map: +-------------------------+ | Person | +-------------------------+ | PersonId | | FullName | +-------------------------+ +-------------------------+ | PersonAddress | +-------------------------+ | PersonId | | AddressId | | IsDefault | +-------------------------+ +-------------------------+ | Address | +-------------------------+ | AddressId | | State | +-------------------------+ And the following classes: public class Person { public virtual int Id { get; set; } public virtual string FullName { get; set; } } public class PersonAddress { public virtual Person Person { get; set; } public virtual Address Address { get; set; } public virtual bool IsDefault { get; set; } } public class Address { public virtual int Id { get; set; } public virtual string State { get; set; } } And finally the mappings: public class PersonMap : ClassMap<Person> { public PersonMap() { Id(x => x.Id, "PersonId"); } } public class PersonAddressMap : ClassMap<PersonAddress> { public PersonAddressMap() { CompositeId().KeyProperty(x => x.Person, "PersonID") .KeyProperty(x => x.Address, "AddressID"); } } public class AddressMap: ClassMap<Address> { public AddressMap() { Id(x => x.Id, "AddressId"); } } Assume I cannot alter the tables. If I take the mapping class (PersonAddress) out of the equation, everything works fine. If I put it back in I get: Could not determine type for: Person, Person, Version=1.0, Culture=neutral, PublicKeyToken=null, for columns: NHibernate.Mapping.Column(PersonId) What am I missing here? I'm sure this must be simple.

  • jquery animate() problem (syntax ?)

    - by meo
    $('#somediv').stop(false, true).animate({marginLeft: '-=' + e.width() + 'px'}, options.speed, function(){ options.onNewSlide() }) e.with() returns 640 opctions.speed contains 800 options.onNewSlide() contains a a custom callback function It works fine in firefox. But i debugged it with jquery.lint because it was throwing some random error in IE. lint tells me: When I called animate(...) with your args, an error was thrown! TypeError: c.speed is not a function { message="c.speed is not a function", more...} You passed: [Object { marginLeft="-=640px"}, 800, function()] and it indicates me the line i have posted. I have checked the jquery doc, but my syntax seams ok. Do you know what i am doing wrong? PS: i use jquery 1.4.2 from the google API you can see the error here: http://meodai.ch/slider/ (i know the code is under construction, but still)

  • some problem with iOS 4.2.1

    - by bicbac
    Hi, I've been developing an app with MacBook Pro (MBP) so far. Last week one of my friends gave me new macbook air 11"(MBA). so Now I can test my code with more than one machine with the same version of developing tools - Both machine has Xcode (3.2.5) and iOS SDK 4.2.1). After some point my app starts get terminated suddenly(iPhone sumulator), and I was using MBP. I got no error message whatsoever. it just stops. I reckon the crash comes from dealing with memory, like 'release'/ 'double-release'. (I'm not 100% sure though). Anyway I thought there must be some mistake within my code for sure. -Confusion starts from this part.- With my MBA, on the other hand, I don'y see any crash. It just works fine. There is nothing different between MBA & MBP except the h/w specifications. Same code, same versions of XCode and iOS SDK. Is the fact that no crash at MBA suggesting that I have to look somewhere else than the code itself? I red some article and Q&As on iOS4.2.1 and XCode 3.2.5 that the most recent version of XCode doesn't recognize the iOS 4.2.1 since the 4.2.1 came out later the 3.2.5. Is it the reason? I have no idea at this moment what should be the next move. thanks

  • Slideshow positioning problem

    - by James
    I have a javascript slideshow that works perfectly on Windows 7, Firefox, Chrome, IE 8+ (I don't have the resources to check 6 or 7) and Opera. But I've been told that when on xp with IE 7 the slidshow gets thrown off screen to the right. What could my issue be? Here is my css: #page { width:940px; margin: auto; } gallery { position:relative; padding:0px; margin:5px 0px; width:940px; height:320px; } gallery li { display: block; width:940px; height:320 list-style:none; } And here is my javascript: var galleryId = 'gallery'; var gallery; var galleryImages; var currentImage; var previousImage; var preInitTimer; preInit(); function preInit() { if ((document.getElementById)&&(gallery=document.getElementById(galleryId))) { gallery.style.visibility = "hidden"; if (typeof preInitTimer != 'undefined') clearTimeout(preInitTimer); } else { preInitTimer = setTimeout("preInit()",2); } } function fader(imageNumber,opacity) { var obj=galleryImages[imageNumber]; if (obj.style) { if (obj.style.MozOpacity!=null) { obj.style.MozOpacity = (opacity/100) - .001; } else if (obj.style.opacity!=null) { obj.style.opacity = (opacity/100) - .001; } else if (obj.style.filter!=null) { obj.style.filter = "alpha(opacity="+opacity+")"; } } } function fadeInit() { if (document.getElementById) { preInit(); galleryImages = new Array; var node = gallery.firstChild; while (node) { if (node.nodeType==1) { galleryImages.push(node); } node = node.nextSibling; } for(i=0;i galleryImages[i].style.position='absolute'; galleryImages[i].style.top=0; galleryImages[i].style.zIndex=0; fader(i,0); } gallery.style.visibility = 'visible'; currentImage=0; previousImage=galleryImages.length-1; opacity=100; fader(currentImage,100); window.setTimeout("crossfade(100)", 1000); } } function crossfade(opacity) { if (opacity < 100) { fader(currentImage,opacity); opacity += 9; window.setTimeout("crossfade("+opacity+")", 50); } else { fader(previousImage,0); previousImage=currentImage; currentImage+=1; if (currentImage=galleryImages.length) { currentImage=0; } galleryImages[previousImage].style.zIndex = 0; galleryImages[currentImage].style.zIndex = 100; opacity=0; window.setTimeout("crossfade("+opacity+")", 5000); } } addEvent(window,'load',fadeInit) function addEvent(elm, evType, fn, useCapture) { if (elm.addEventListener){ elm.addEventListener(evType, fn, useCapture); return true; } else if (elm.attachEvent){ var r = elm.attachEvent("on"+evType, fn); return r; } } And ideas?

  • Problem with HttpService POST

    - by Lost_in_code
    I'm trying to send some data to PHP using HTTPService POST but for some reason it's not working. The same example works with GET but not with POST: private function start():void{ var param:Object = {}; param.date = "2010-10-10"; userRequest.send(param); userRequest.addEventListener(ResultEvent.RESULT, result); userRequest.addEventListener(FaultEvent.FAULT, fault); } private function fault(e:FaultEvent):void{ trace(e.message); } private function result(e:ResultEvent):void{ trace(e.result); } <mx:HTTPService id="userRequest" url="http://localhost:8888/api" useProxy="false" method="POST"/> And here's the PHP code: $d = $_POST['date']; echo $d; if($d == ""){ trace("Date not found!"); die(); } This is the error I'm getting: "Error #2032: Stream Error. URL: http://localhost:8888/api" But when I change the method in HTTPService to GET and in PHP I get the result as expected - PHP sends back the date: 2010-10-10 What am I doing wrong?

  • problem loading resource from class library

    - by mishal153
    I have a class library (mylibrary) which has a resource called "close.png". I used redGate reflector to confirm that the resource is actually present in the dll. Now i use mylibrary.dll in a project where i attempt to extract this "close.png" resource like this : BitmapImage crossImage = new BitmapImage(); crossImage.BeginInit(); crossImage.UriSource = new Uri(@"/mylibrary;component/Resources/close.png", UriKind.RelativeOrAbsolute); crossImage.EndInit(); This BitmapImage crossImage is then used like : Button closeButton = new Button() { Content = new System.Windows.Controls.Image() { Source = crossImage }, MaxWidth = 20, MaxHeight = 20 }; On doing this i get no exceptions being thrown but the button shows no image. Also, i do see some exception info if i investigate the button's 'content' in the debugger.

  • Rails + Passenger CSS problem

    - by Dan
    I'm trying to deploy my first Rails app. At first, I was getting the following error: ActionView::TemplateError (Permission denied) I set the permissions of the stylesheets folder to 777 (just for now until I work out what's going wrong) and the application started to work. However, it is not picking up any of the stylesheets (everything is displayed in plain text). If I view the source code and click the CSS links, I just get a blank page. Javascripts however, seem to be working just fine. VHost Config: <VirtualHost *:80> ServerName xxxx.xxx.com DocumentRoot /home/myapp/public <Directory /home/myapp/public> Allow from All AllowOverride all Options -MultiViews </Directory> </VirtualHost> Can anyone help? Any advice appreciated. Thanks.

  • Array of Arrays - writing to File problem

    - by iFloh
    Hi, and again my array of arrays ... I try to improve my app performance by buffering arrays on file for later reuse. I have an NSMutableArray that contains about 30 NSMutableArrays with NSNumber, NSDate and NSString Objects. I try to write the file using this call: bool result = [myArray writeToFile:[fileMethods getFullPath:[NSString stringWithFormat:@"iEts%@.arr", [aDate shortDateString]]] atomically:NO]; = result = FALSE. The Path method is: + (NSString *) getFullPath:(NSString *)forFileName { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; return [documentsDirectory stringByAppendingPathComponent:forFileName]; } and the aDate call returns a shortDateString with ddMMyy. The NSLog NSLog(@"%@", [fileMethods getFullPath:[NSString stringWithFormat:@"iEts%@.arr", [aDate shortDateString]]]); on the path generation returns: /Users/me/Library/Application Support/iPhone Simulator/User/Applications/86729620-EC1D-4C10-A799-0C638BB27933/Documents/iEts010510.arr FURTHER: It must have something to do with the Array of Arrays, since I also write 3 further simple arrays (containing NSStrings) that all succeed. The Array of Arrays gets generated using the addObject method Any ideas what could cause the trouble?
