Probelm with String.split() in java

- by Matt

What I am trying to do is read a .java file, and pick out all of the identifiers and store them in a list. My problem is with the .split() method. If you run this code the way it is, you will get ArrayOutOfBounds, but if you change the delimiter from "." to anything else, the code works. But I need to lines parsed by "." so is there another way I could accomplish this? import java.io.BufferedReader; import java.io.FileNotFoundException; import java.io.FileReader; import java.io.IOException; import java.util.*; public class MyHash { private static String[] reserved = new String[100]; private static List list = new LinkedList(); private static List list2 = new LinkedList(); public static void main (String args[]){ Hashtable hashtable = new Hashtable(997); makeReserved(); readFile(); String line; ListIterator itr = list.listIterator(); int listIndex = 0; while (listIndex < list.size()) { if (itr.hasNext()){ line = itr.next().toString(); //PROBLEM IS HERE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Visualising a 'Smarties' lid using XAML (WPF/Silverlight, Visual Studio/Blend)

- by Mr. Disappointment

Hi folks, First off, to clarify something in the title which could well be ambiguous/misleading, I'd like to inform you of my definition of 'Smarties', as I know often products are available all over - only under a different alias. Smarties are a candy product in the UK, little chocolate drops covered in a crispy shell which are distributed in a card tube, this tube used to have a plastic lid/top with an individual letter on the underside (they've taken a more economical approach as of late), the lid/top of the old-style tube is the main element of this question. Familiarisation Link Lid View Link Okay, now with the seller-type pitch out of the way (no, I don't work for Nestlé ;)), hopefully the question is becoming rather clear. Essentially, I'd like to recreate one of these lids using XAML, ultimately to be utilised in a Silverlight web application. That is, I'd like to result in a reusable control, of which the following is true: It looks like a Smarties lid. The colour can be specified. The letter can be specified. The control can be rotated to display either side. The second two seem trivial, but we must bare in mind that the background colour specified will almost, if not always, be the same as the foreground, leaving a visibility issue where the character content is concerned; as for the rotation, I'm hoping this kind of functionality is reasonably available, and acceptable to implement. So, to put this out there, consider a control named SmartiesLid which derives from ToggleButton (appropriate?) and further plotted out using a style in a resource dictionary which applies to it, as follows: <Style TargetType="local:SmartiesLid"> <Setter Property="Background" Value="Red"/> <Setter Property="Foreground" Value="Red"/> <Setter Property="VerticalContentAlignment" Value="Center"/> <Setter Property="HorizontalContentAlignment" Value="Center"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="local:SmartiesLid"> <Grid x:Name="LayoutRoot"> <Grid.ColumnDefinitions> <ColumnDefinition Width=".05*"/> <ColumnDefinition/> <ColumnDefinition/> <ColumnDefinition Width=".05*"/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height=".05*"/> <RowDefinition/> <RowDefinition/> <RowDefinition Height=".05*"/> <RowDefinition Height=".1*"/> </Grid.RowDefinitions> <Ellipse Grid.RowSpan="4" Grid.ColumnSpan="4" Fill="{TemplateBinding Background}" Stroke="Transparent"/> <Ellipse Grid.RowSpan="2" Grid.ColumnSpan="2" Grid.Column="1" Grid.Row="1" Fill="{TemplateBinding Background}" Stroke="Transparent"> <Ellipse.Effect> <DropShadowEffect Direction="280" ShadowDepth="6" BlurRadius="6"/> </Ellipse.Effect> </Ellipse> <TextBlock Grid.RowSpan="2" Grid.ColumnSpan="2" Grid.Column="1" Grid.Row="1" Name="LetterTextBlock" Text="{TemplateBinding Content}" Foreground="{TemplateBinding Foreground}" FontSize="190" HorizontalAlignment="Center" VerticalAlignment="Center"> </TextBlock>  </Grid> <ControlTemplate.Resources> <TranslateTransform x:Key="IndentTransform" X="10" /> <RotateTransform x:Key="RotateTransform" Angle="0" /> <Storyboard x:Key="MouseOver"> </Storyboard> <Storyboard x:Key="MouseLeave"> </Storyboard> </ControlTemplate.Resources> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="true"> <Trigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource MouseOver}"/> </Trigger.EnterActions> <Trigger.ExitActions> <BeginStoryboard Storyboard="{StaticResource MouseLeave}"/> </Trigger.ExitActions> </Trigger> <Trigger Property="IsPressed" Value="true"> <Setter TargetName="LayoutRoot" Property="RenderTransform" Value="{StaticResource IndentTransform}"/> </Trigger> <Trigger Property="IsChecked" Value="true"> <Setter TargetName="LayoutRoot" Property="RenderTransform" Value="{StaticResource RotateTransform}"/> </Trigger> <Trigger Property="IsEnabled" Value="False"> <Setter Property="Foreground" Value="Gray"/> <Setter Property="Opacity" Value="0.5"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> With this in mind, can anyone give input on, in decreasing order of my incompetence in an area: Designing the overall look and feel of the damn thing (I'm no designer, and while I could hack away at this single control for days and potentially get something relatively useful, it's always a gamble). The particular barrier for me here is 'pathing' the tab of the lid, as you will see in the XAML as an element commented out. Should Path be used, or would it be more appropriate to transform a rectangle with rounded corners, or any specific suggestions? Bevelling the individually displayed letter; as detailed above, when the colour of both the foreground and background are the same then this will be invisible if no effects are applied, also for a decent level of realism I'd like to be able to apply such an effect/s. So far use of DropShadow and Balder3DEngine have fulfilled my requirements for graphics in XAML, how achievable is a bevel effect? Rotating the control on mouse-click, that is, showing the opposing face. Is this going to be possible using a style and XAML only for the design? Or is it that ugliness may rear it's head in the form of code-behind to show/hide embedded controls? Should the faces be separate controls and later somehow combined? Allowing the control to size dynamically. I'm supposing I will be able to convert a solid, absolute layout to a nice generic one when I actually have the former in place. Obviously this entails sizing the centralised letter and the lid 'tab', but that's it really, other than keeping the aspect ratio equal (since the ellipses grow nicely with the grid). Any suggestions to approaching this would be greatly appreciated, particularly with a dynamically growing font - I've done that before in a web-imaging scenario using code and System.Drawing, and wouldn't like to approach it in even a similar way. By the way, the reason I specify both WPF and Silverlight is that, from my current knowledge, the inputs being written targeting either of these will be fairly transferable for similar output by the other, albeit not without alterations in either scenario. The resulting application is in fact destined to be written in Silverlight, however, so I don't fancy inviting anything from WPF which will guarantee my only being able to convert 90% of it. I'll go give this little project a start, maybe in Blend(?), hopefully can catch up with some advice shortly. Thanks, Mr. D EDIT: Next question, ought this to be broken up into separate questions? :/

Uploading multiple files using Spring MVC 3.0.2 after HiddenHttpMethodFilter has been enabled

- by Tiny

I'm using Spring version 3.0.2. I need to upload multiple files using the multiple="multiple" attribute of a file browser such as, <input type="file" id="myFile" name="myFile" multiple="multiple"/> (and not using multiple file browsers something like the one stated by this answer, it indeed works I tried). Although no versions of Internet Explorer supports this approach unless an appropriate jQuery plugin/widget is used, I don't care about it right now (since most other browsers support this). This works fine with commons fileupload but in addition to using RequestMethod.POST and RequestMethod.GET methods, I also want to use other request methods supported and suggested by Spring like RequestMethod.PUT and RequestMethod.DELETE in their own appropriate places. For this to be so, I have configured Spring with HiddenHttpMethodFilter which goes fine as this question indicates. but it can upload only one file at a time even though multiple files in the file browser are chosen. In the Spring controller class, a method is mapped as follows. @RequestMapping(method={RequestMethod.POST}, value={"admin_side/Temp"}) public String onSubmit(@RequestParam("myFile") List<MultipartFile> files, @ModelAttribute("tempBean") TempBean tempBean, BindingResult error, Map model, HttpServletRequest request, HttpServletResponse response) throws IOException, FileUploadException { for(MultipartFile file:files) { System.out.println(file.getOriginalFilename()); } } Even with the request parameter @RequestParam("myFile") List<MultipartFile> files which is a List of type MultipartFile (it can always have only one file at a time). I could find a strategy which is likely to work with multiple files on this blog. I have gone through it carefully. The solution below the section SOLUTION 2 – USE THE RAW REQUEST says, If however the client insists on using the same form input name such as ‘files[]‘ or ‘files’ and then populating that name with multiple files then a small hack is necessary as follows. As noted above Spring 2.5 throws an exception if it detects the same form input name of type file more than once. CommonsFileUploadSupport – the class which throws that exception is not final and the method which throws that exception is protected so using the wonders of inheritance and subclassing one can simply fix/modify the logic a little bit as follows. The change I’ve made is literally one word representing one method invocation which enables us to have multiple files incoming under the same form input name. It attempts to override the method protected MultipartParsingResult parseFileItems(List fileItems, String encoding) {} of the abstract class CommonsFileUploadSupport by extending the class CommonsMultipartResolver such as, package multipartResolver; import java.io.UnsupportedEncodingException; import java.util.HashMap; import java.util.Iterator; import java.util.List; import java.util.Map; import javax.servlet.ServletContext; import org.apache.commons.fileupload.FileItem; import org.springframework.util.StringUtils; import org.springframework.web.multipart.MultipartException; import org.springframework.web.multipart.MultipartFile; import org.springframework.web.multipart.commons.CommonsMultipartFile; import org.springframework.web.multipart.commons.CommonsMultipartResolver; final public class MultiCommonsMultipartResolver extends CommonsMultipartResolver { public MultiCommonsMultipartResolver() { } public MultiCommonsMultipartResolver(ServletContext servletContext) { super(servletContext); } @Override @SuppressWarnings("unchecked") protected MultipartParsingResult parseFileItems(List fileItems, String encoding) { Map<String, MultipartFile> multipartFiles = new HashMap<String, MultipartFile>(); Map multipartParameters = new HashMap(); // Extract multipart files and multipart parameters. for (Iterator it = fileItems.iterator(); it.hasNext();) { FileItem fileItem = (FileItem) it.next(); if (fileItem.isFormField()) { String value = null; if (encoding != null) { try { value = fileItem.getString(encoding); } catch (UnsupportedEncodingException ex) { if (logger.isWarnEnabled()) { logger.warn("Could not decode multipart item '" + fileItem.getFieldName() + "' with encoding '" + encoding + "': using platform default"); } value = fileItem.getString(); } } else { value = fileItem.getString(); } String[] curParam = (String[]) multipartParameters.get(fileItem.getFieldName()); if (curParam == null) { // simple form field multipartParameters.put(fileItem.getFieldName(), new String[] { value }); } else { // array of simple form fields String[] newParam = StringUtils.addStringToArray(curParam, value); multipartParameters.put(fileItem.getFieldName(), newParam); } } else { // multipart file field CommonsMultipartFile file = new CommonsMultipartFile(fileItem); if (multipartFiles.put(fileItem.getName(), file) != null) { throw new MultipartException("Multiple files for field name [" + file.getName() + "] found - not supported by MultipartResolver"); } if (logger.isDebugEnabled()) { logger.debug("Found multipart file [" + file.getName() + "] of size " + file.getSize() + " bytes with original filename [" + file.getOriginalFilename() + "], stored " + file.getStorageDescription()); } } } return new MultipartParsingResult(multipartFiles, multipartParameters); } } What happens is that the last line in the method parseFileItems() (the return statement) i.e. return new MultipartParsingResult(multipartFiles, multipartParameters); causes a compile-time error because the first parameter multipartFiles is a type of Map implemented by HashMap but in reality, it requires a parameter of type MultiValueMap<String, MultipartFile> It is a constructor of a static class inside the abstract class CommonsFileUploadSupport, public abstract class CommonsFileUploadSupport { protected static class MultipartParsingResult { public MultipartParsingResult(MultiValueMap<String, MultipartFile> mpFiles, Map<String, String[]> mpParams) { } } } The reason might be - this solution is about the Spring version 2.5 and I'm using the Spring version 3.0.2 which might be inappropriate for this version. I however tried to replace the Map with MultiValueMap in various ways such as the one shown in the following segment of code, MultiValueMap<String, MultipartFile>mul=new LinkedMultiValueMap<String, MultipartFile>(); for(Entry<String, MultipartFile>entry:multipartFiles.entrySet()) { mul.add(entry.getKey(), entry.getValue()); } return new MultipartParsingResult(mul, multipartParameters); but no success. I'm not sure how to replace Map with MultiValueMap and even doing so could work either. After doing this, the browser shows the Http response, HTTP Status 400 - type Status report message description The request sent by the client was syntactically incorrect (). Apache Tomcat/6.0.26 I have tried to shorten the question as possible as I could and I haven't included unnecessary code. How could be made it possible to upload multiple files after Spring has been configured with HiddenHttpMethodFilter? That blog indicates that It is a long standing, high priority bug. If there is no solution regarding the version 3.0.2 (3 or higher) then I have to disable Spring support forever and continue to use commons-fileupolad as suggested by the third solution on that blog omitting the PUT, DELETE and other request methods forever. Just curiously waiting for a solution and/or suggestion. Very little changes to the code in the parseFileItems() method inside the class MultiCommonsMultipartResolver might make it to upload multiple files but I couldn't succeed in my attempts (again with the Spring version 3.0.2 (3 or higher)).

A "Trig" Calculating Class

- by Clinton Scott

I have been trying to create a gui that calculates trigonometric functions based off of the user's input. I have had success in the GUI part, but my class that I wrote to hold information using inheritance seems to be messed up, because when I run it gives an error saying: Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - constructor ArcTrigCalcCon in class TrigCalc.ArcTrigCalcCon cannot be applied to given types; required: double,double,double,double,double,double found: java.lang.Double,java.lang.Double,java.lang.Double reason: actual and formal argument lists differ in length at TrigCalc.TrigCalcGUI.(TrigCalcGUI.java:31) at TrigCalc.TrigCalcGUI.main(TrigCalcGUI.java:87) Java Result: 1 and says it is the object causing the problem. Below Will be my code. First I will put up my inheritance class with cosecant secant and cotangent and then my original class with the original 3 trig functions: { public ArcTrigCalcCon(double s, double cs, double t, double csc, double sc, double ct) { // Inherit from the Trig Calc class super(s, cs, t); cosecant = 1/s; secant = 1/cs; cotangent = 1/t; } public void setCsc(double csc) { cosecant = csc; } public void setSec(double sc) { secant = sc; } public void setCot(double ct) { cotangent = ct; } } Here is the first Trigonometric class: public class TrigCalcCon { public double sine; public double cosine; public double tangent; public TrigCalcCon(double s, double cs, double t) { sine = s; cosine = cs; tangent = t; } public void setSin(double s) { sine = s; } public void setCos(double cs) { cosine = cs; } public void setTan(double t) { tangent = t; } public void set(double s, double cs, double t) { sine = s; cosine = cs; tangent = t; } public double getSin() { return Math.sin(sine); } public double getCos() { return Math.cos(cosine); } public double getTan() { return Math.tan(tangent); } } and here is the demo class to run the gui: public class TrigCalcGUI extends JFrame implements ActionListener { // Instance Variables private String input; private Double s, cs, t, csc, sc, ct; private JPanel mainPanel, sinPanel, cosPanel, tanPanel, cscPanel, secPanel, cotPanel, buttonPanel, inputPanel, displayPanel; // Panel Display private JLabel sinLabel, cosLabel, tanLabel, secLabel, cscLabel, cotLabel, inputLabel;

Simple C++ program on multidimensional arrays - Getting C2143 error among others. Not sure why?

Reading in a 5000 line text file on the Iphone

- by howsyourface

Gday, I am trying to create a tiled map for my game, i have had this previously working using other xml methods but i had memory leaks and all sorts of errors. However i had a map load time of about 2.5 - 3 seconds. So i rewrote all of the code using NSMutableStrings and NSStrings. After my best attempt at optomizing it i had a map load time of 10 - 11 seconds, which is far too slow. So i have now rewritten the code using char* arrays, only to now have a load time of 18 seconds -_-. Here is the latest code, i don't know much c so i could have easily botched the whole thing up. FILE* file = fopen(a, "r"); fseek(file, 0L, SEEK_END); length = ftell(file); fseek(file,0L, SEEK_SET); char fileText[length +1]; char buffer[1024];// = malloc(1024); while(fgets(buffer, 1024, file) != NULL) { strncat(fileText, buffer, strlen(buffer));

Thanks for all your efforts.

HTML/jQuery/CSS Drop Down Menu Issue / Safari

I have a simple top bar using jquery like the one on stackoverflow, but i want it to only appear on the first time a person visits the website. below is the HTML followed by the "bxSlider.js" file <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script> <script type="text/javascript" src="bxSlider.js"></script> <title>topbar</title> <style type="text/css" media="screen"> #message { font-family:Arial,Helvetica,sans-serif;

Can't figure out where race condition is occuring

- by Nik

I'm using Valgrind --tool=drd to check my application that uses Boost::thread. Basically, the application populates a set of "Book" values with "Kehai" values based on inputs through a socket connection. On a seperate thread, a user can connect and get the books send to them. Its fairly simple, so i figured using a boost::mutex::scoped_lock on the location that serializes the book and the location that clears out the book data should be suffice to prevent any race conditions. Here is the code: void Book::clear() { boost::mutex::scoped_lock lock(dataMutex); for(int i =NUM_KEHAI-1; i >= 0; --i) { bid[i].clear(); ask[i].clear(); } } int Book::copyChangedKehaiToString(char* dst) const { boost::mutex::scoped_lock lock(dataMutex); sprintf(dst, "%-4s%-13s",market.c_str(),meigara.c_str()); int loc = 17; for(int i = 0; i < Book::NUM_KEHAI; ++i) { if(ask[i].changed > 0) { sprintf(dst+loc,"A%i%-21s%-21s%-21s%-8s%-4s",i,ask[i].price.c_str(),ask[i].volume.c_str(),ask[i].number.c_str(),ask[i].postTime.c_str(),ask[i].status.c_str()); loc += 77; } } for(int i = 0; i < Book::NUM_KEHAI; ++i) { if(bid[i].changed > 0) { sprintf(dst+loc,"B%i%-21s%-21s%-21s%-8s%-4s",i,bid[i].price.c_str(),bid[i].volume.c_str(),bid[i].number.c_str(),bid[i].postTime.c_str(),bid[i].status.c_str()); loc += 77; } } return loc; } The clear() function and the copyChangedKehaiToString() function are called in the datagetting thread and data sending thread,respectively. Also, as a note, the class Book: struct Book { private: Book(const Book&); Book& operator=(const Book&); public: static const int NUM_KEHAI=10; struct Kehai; friend struct Book::Kehai; struct Kehai { private: Kehai& operator=(const Kehai&); public: std::string price; std::string volume; std::string number; std::string postTime; std::string status; int changed; Kehai(); void copyFrom(const Kehai& other); Kehai(const Kehai& other); inline void clear() { price.assign(""); volume.assign(""); number.assign(""); postTime.assign(""); status.assign(""); changed = -1; } }; std::vector<Kehai> bid; std::vector<Kehai> ask; tm recTime; mutable boost::mutex dataMutex; Book(); void clear(); int copyChangedKehaiToString(char * dst) const; }; When using valgrind --tool=drd, i get race condition errors such as the one below: ==26330== Conflicting store by thread 1 at 0x0658fbb0 size 4 ==26330== at 0x653AE68: std::string::_M_mutate(unsigned int, unsigned int, unsigned int) (in /usr/lib/libstdc++.so.6.0.8) ==26330== by 0x653AFC9: std::string::_M_replace_safe(unsigned int, unsigned int, char const*, unsigned int) (in /usr/lib/libstdc++.so.6.0.8) ==26330== by 0x653B064: std::string::assign(char const*, unsigned int) (in /usr/lib/libstdc++.so.6.0.8) ==26330== by 0x653B134: std::string::assign(char const*) (in /usr/lib/libstdc++.so.6.0.8) ==26330== by 0x8055D64: Book::Kehai::clear() (Book.h:50) ==26330== by 0x8094A29: Book::clear() (Book.cpp:78) ==26330== by 0x808537E: RealKernel::start() (RealKernel.cpp:86) ==26330== by 0x804D15A: main (main.cpp:164) ==26330== Allocation context: BSS section of /usr/lib/libstdc++.so.6.0.8 ==26330== Other segment start (thread 2) ==26330== at 0x400BB59: pthread_mutex_unlock (drd_pthread_intercepts.c:633) ==26330== by 0xC59565: pthread_mutex_unlock (in /lib/libc-2.5.so) ==26330== by 0x805477C: boost::mutex::unlock() (mutex.hpp:56) ==26330== by 0x80547C9: boost::unique_lock<boost::mutex>::~unique_lock() (locks.hpp:340) ==26330== by 0x80949BA: Book::copyChangedKehaiToString(char*) const (Book.cpp:134) ==26330== by 0x80937EE: BookSerializer::serializeBook(Book const&, std::string const&) (BookSerializer.cpp:41) ==26330== by 0x8092D05: BookSnapshotManager::getSnaphotDataList() (BookSnapshotManager.cpp:72) ==26330== by 0x8088179: SnapshotServer::getDataList() (SnapshotServer.cpp:246) ==26330== by 0x808870F: SnapshotServer::run() (SnapshotServer.cpp:183) ==26330== by 0x808BAF5: boost::_mfi::mf0<void, RealThread>::operator()(RealThread*) const (mem_fn_template.hpp:49) ==26330== by 0x808BB4D: void boost::_bi::list1<boost::_bi::value<RealThread*> >::operator()<boost::_mfi::mf0<void, RealThread>, boost::_bi::list0>(boost::_bi::type<void>, boost::_mfi::mf0<void, RealThread>&, boost::_bi::list0&, int) (bind.hpp:253) ==26330== by 0x808BB90: boost::_bi::bind_t<void, boost::_mfi::mf0<void, RealThread>, boost::_bi::list1<boost::_bi::value<RealThread*> > >::operator()() (bind_template.hpp:20) ==26330== Other segment end (thread 2) ==26330== at 0x400B62A: pthread_mutex_lock (drd_pthread_intercepts.c:580) ==26330== by 0xC59535: pthread_mutex_lock (in /lib/libc-2.5.so) ==26330== by 0x80546B8: boost::mutex::lock() (mutex.hpp:51) ==26330== by 0x805473B: boost::unique_lock<boost::mutex>::lock() (locks.hpp:349) ==26330== by 0x8054769: boost::unique_lock<boost::mutex>::unique_lock(boost::mutex&) (locks.hpp:227) ==26330== by 0x8094711: Book::copyChangedKehaiToString(char*) const (Book.cpp:113) ==26330== by 0x80937EE: BookSerializer::serializeBook(Book const&, std::string const&) (BookSerializer.cpp:41) ==26330== by 0x808870F: SnapshotServer::run() (SnapshotServer.cpp:183) ==26330== by 0x808BAF5: boost::_mfi::mf0<void, RealThread>::operator()(RealThread*) const (mem_fn_template.hpp:49) ==26330== by 0x808BB4D: void boost::_bi::list1<boost::_bi::value<RealThread*> >::operator()<boost::_mfi::mf0<void, RealThread>, boost::_bi::list0>(boost::_bi::type<void>, boost::_mfi::mf0<void, RealThread>&, boost::_bi::list0&, int) (bind.hpp:253) For the life of me, i can't figure out where the race condition is. As far as I can tell, clearing the kehai is done only after having taken the mutex, and the same holds true with copying it to a string. Does anyone have any ideas what could be causing this, or where I should look? Thank you kindly.

Can anyone explain why my crypto++ decrypted file is 16 bytes short?

- by Tom Williams

I suspect it might be too much to hope for, but can anyone with experience with crypto++ explain why the "decrypted.out" file created by main() is 16 characters short (which probably not coincidentally is the block size)? I think the issue must be in CryptStreamBuffer::GetNextChar(), but I've been staring at it and the crypto++ documentation for hours. Any other comments about how crummy or naive my std::streambuf implementation are also welcome ;-) And I've just noticed I'm missing some calls to delete so you don't have to tell me about those.

Strange problem with Random Access Filing in C++

- by sam

This is a simple random access filing program . The problem arises where i want to write data randomly. If I write any where in the file the previous records are set to 0. the last 1 which is being entered currently holds the correct value all others =0. This is the code #include <iostream> #include<fstream> #include<string> using namespace std; class name { int id; int pass; public: void writeBlank(); void writedata(); void readdata(); void readall(); int getid() { return id; } int getpass() { return pass; } void setid(int i) { id=i; } void setpass(int p) { pass=p; } }; void name::writeBlank() { name person; person.setid(0); person.setpass(0); int i; ofstream out("pass.txt",ios::binary); if ( !out ) { cout << "File could not be opened." << endl; } for(i=0;i<10;i++) //make 10 records { cout<<"Put pointer is at: "<<out.tellp()<<endl; cout<<"Blank record "<<i<<" is: "<<person.getid()<<" "<<person.getpass()<<" and size: "<<sizeof(person)<<endl; cout<<"Put pointer is at: "<<out.tellp()<<endl; out.write(reinterpret_cast< const char * >(&person),sizeof(name)); } } void name::writedata() { ofstream out("pass.txt",ios::binary|ios::out); name n1; int iD,p; cout<<"ID?"; cin>>iD; n1.setid(iD); cout<<"Enter password"; cin>>p; n1.setpass(p); if (!out ) { cout << "File could not be opened." << endl; } out.seekp((n1.getid()-1)*sizeof(name),ios::beg); //pointer moves to desired location where we have to store password according to its ID(index) cout<<"File pointer is at: "<<out.tellp()<<endl; out.write(reinterpret_cast<const char*> (&n1), sizeof(name)); //write on that pointed location } void name::readall() { name n1; ifstream in("pass.txt",ios::binary); if ( !in ) { cout << "File could not be opened." << endl; } in.read( reinterpret_cast<char *>(&n1), sizeof(name) ); while ( !in.eof() ) { // display record cout<<endl<<"password at this index is:"<<n1.getpass()<<endl; cout<<"File pointer is at: "<<in.tellg()<<endl; // read next from file in.read( reinterpret_cast< char * >(&n1), sizeof(name)); } // end while } void name::readdata() { ifstream in("pass.txt",ios::binary); if ( !in ) { cout << "File could not be opened." << endl; } in.seekg((getid()-1)*sizeof(name)); //pointer moves to desired location where we have to read password according to its ID(index) cout<<"File pointer is at: "<<in.tellg()<<endl; in.read((char* )this,sizeof(name)); //reads from that pointed location cout<<endl<<"password at this index is:"<<getpass()<<endl; } int main() { name n1; cout<<"Enter 0 to write blank records"<<endl; cout<<"Enter 1 for new account"<<endl; cout<<"Enter 2 to login"<<endl; cout<<"Enter 3 to read all"<<endl; cout<<"Enter 9 to exit"<<endl; int option; cin>>option; while(option==0 || option==1 || option==2 || option==3) { if (option == 0) n1.writeBlank(); if(option==1) { /*int iD,p; cout<<"ID?"; cin>>iD; n1.setid(iD); cout<<"Enter password"; cin>>p; n1.setpass(p);*/ n1.writedata(); } int ind; if(option==2) { cout<<"Index?"; cin>>ind; n1.setid(ind); n1.readdata(); } if(option == 3) n1.readall(); cout<<"Enter 0 to write blank records"<<endl; cout<<"Enter 1 for new account"<<endl; cout<<"Enter 2 to login"<<endl; cout<<"Enter 3 to read all"<<endl; cout<<"Enter 9 to exit"<<endl; cin>>option; } } I Cant understand Y the previous records turn 0.

java.lang.NullPointerException exception in my controller file (using Spring Hibernate Maven)

- by mrjayviper

The problem doesn't seemed to have anything to do with Hibernate. As I've commented the Hibernate stuff but I'm still getting it. If I comment out this line message = staffDAO.searchForStaff(search); in my controller file, it goes through ok. But I don't see anything wrong with searchForStaff function. It's a very simple function that just returns the string "test" and run system.out.println("test"). Can you please help? thanks But this is the error that I'm getting: SEVERE: Servlet.service() for servlet [spring] in context with path [/directorymaven] threw exception [Request processing failed;

HTML/CSS formating

- by Codeguy007

I'm having to issues lining up items properly in my html code. I am not sure why they are lining up the way I want them to. First the header My Color Library is a full line height above the horizontal ruler. I want it right above the ruler. Second my X box in the td with the background is justified right fine but I actually want it in the top right hand corner not centered vertically. Here's some example html: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>FunctionalColor&Design</title> </head> <html> <body> <table style="width=900px; margin-left: auto; margin-right: auto;"> <tr> <td> <P> <div style="font-size: 1em; line-height: 1em; font-weight: bolder; padding: 0px;">My Color Library</div> <div align="right" class="removeall"> <a href="colors"> <img src="http://2100computerlane.net/workingproject/images/x-button.png" /> <bold>Remove All</bold> </a> </div> <HR/></p> <div class="mycolor"> <table> <tr> <td style="border: none; background-color: #f8d3cf; width:125px; height:80px; border-spacing: 10px; padding:0;"> <div style="padding:0; vertical-align:top;" align="right" class="remove"> <a href="f8d3cf" style="padding: 0px;"> <img src="http://2100computerlane.net/workingproject/images/x-button.png" style="padding: 0px;"/> </a> </div> </td> <td style="border: none; width:10px;"></td> <td style="border: none; background-color: #f8d3cf; width:125px; height:80px; border-spacing: 10px; padding:0;"></td> <td style="border: none; width:10px;"></td> <td style="border: none; background-color: #f8d3cf; width:125px; height:80px; border-spacing: 10px; padding:0;"></td> <td style="border: none; width:10px;"></td> <td style="border: none; background-color: #f8d3cf; width:125px; height:80px; border-spacing: 10px; padding:0;"></td> <td style="border: none; width:10px;"></td> <td style="border: none; background-color: #f8d3cf; width:125px; height:80px; border-spacing: 10px; padding:0;"></td> <td style="border: none; width:10px;"></td> <td style="border: none; background-color: #f8d3cf; width:125px; height:80px; border-spacing: 10px; padding:0;"></td> <tr> <td style="border: none; font:.6em Arial, Helvetica, sans-serif; width:125px; height:20px;">Desert Warmth<br/>70YR 56/190 A0542</td> </tr> </table> </div> </td> </tr> </table> </body> </html>

c# Unable to open file for reading

- by Maks

I'm writing a program that uses FileSystemWatcher to monitor changes to a given directory, and when it recieves OnCreated or OnChanged event, it copies those created/changed files to a specified directorie(s). At first I had problems with the fact that OnChanged/OnCreated events can be sent twice (not acceptable in case it needed to process 500MB file) but I made a way around this and with what I'm REALLY STUCKED with is getting the following IOException: The process cannot access the file 'C:\Where are Photos\bookmarks (11).html' because it is being used by another process. Thus, preventing the program from copying all the files it should. So as I mentioned, when user uses this program he/she specifes monitored directory, when user copies/creates/changes file in that directory, program should get OnCreated/OnChanged event and then copy that file to few other directories. Above error happens in all casess, if user copies few files that needs to owerwrite other ones in folder being monitored or when copying bulk of several files or even sometimes when copying one file in a monitored directory. Whole program is quite big so I'm sending the most important parts. OnCreated: private void OnCreated(object source, FileSystemEventArgs e) { AddLogEntry(e.FullPath, "created", ""); // Update last access data if it's file so the same file doesn't // get processed twice because of sending another event. if (fileType(e.FullPath) == 2) { lastPath = e.FullPath; lastTime = DateTime.Now; } // serves no purpose now, it will be remove soon string fileName = GetFileName(e.FullPath); // copies file from source to few other directories Copy(e.FullPath, fileName); Console.WriteLine("OnCreated: " + e.FullPath); } OnChanged: private void OnChanged(object source, FileSystemEventArgs e) { // is it directory if (fileType(e.FullPath) == 1) return; // don't mind directory changes itself // Only if enough time has passed or if it's some other file // because two events can be generated int timeDiff = ((TimeSpan)(DateTime.Now - lastTime)).Seconds; if ((timeDiff < minSecsDiff) && (e.FullPath.Equals(lastPath))) { Console.WriteLine("-- skipped -- {0}, timediff: {1}", e.FullPath, timeDiff); return; } // Update last access data for above to work lastPath = e.FullPath; lastTime = DateTime.Now; // Only if size is changed, the rest will handle other handlers if (e.ChangeType == WatcherChangeTypes.Changed) { AddLogEntry(e.FullPath, "changed", ""); string fileName = GetFileName(e.FullPath); Copy(e.FullPath, fileName); Console.WriteLine("OnChanged: " + e.FullPath); } } fileType: private int fileType(string path) { if (Directory.Exists(path)) return 1; // directory else if (File.Exists(path)) return 2; // file else return 0; } Copy: private void Copy(string srcPath, string fileName) { foreach (string dstDirectoy in paths) { string eventType = "copied"; string error = "noerror"; string path = ""; string dirPortion = ""; // in case directory needs to be made if (srcPath.Length > fsw.Path.Length) { path = srcPath.Substring(fsw.Path.Length, srcPath.Length - fsw.Path.Length); int pos = path.LastIndexOf('\\'); if (pos != -1) dirPortion = path.Substring(0, pos); } if (fileType(srcPath) == 1) { try { Directory.CreateDirectory(dstDirectoy + path); //Directory.CreateDirectory(dstDirectoy + fileName); eventType = "created"; } catch (IOException e) { eventType = "error"; error = e.Message; } } else { try { if (!overwriteFile && File.Exists(dstDirectoy + path)) continue; // create new dir anyway even if it exists just to be sure Directory.CreateDirectory(dstDirectoy + dirPortion); // copy file from where event occured to all specified directories using (FileStream fsin = new FileStream(srcPath, FileMode.Open, FileAccess.Read, FileShare.Read)) { using (FileStream fsout = new FileStream(dstDirectoy + path, FileMode.Create, FileAccess.Write)) { byte[] buffer = new byte[32768]; int bytesRead = -1; while ((bytesRead = fsin.Read(buffer, 0, buffer.Length)) > 0) fsout.Write(buffer, 0, bytesRead); } } } catch (Exception e) { if ((e is IOException) && (overwriteFile == false)) { eventType = "skipped"; } else { eventType = "error"; error = e.Message; // attempt to find and kill the process locking the file. // failed, miserably System.Diagnostics.Process tool = new System.Diagnostics.Process(); tool.StartInfo.FileName = "handle.exe"; tool.StartInfo.Arguments = "\"" + srcPath + "\""; tool.StartInfo.UseShellExecute = false; tool.StartInfo.RedirectStandardOutput = true; tool.Start(); tool.WaitForExit(); string outputTool = tool.StandardOutput.ReadToEnd(); string matchPattern = @"(?<=\s+pid:\s+)\b(\d+)\b(?=\s+)"; foreach (Match match in Regex.Matches(outputTool, matchPattern)) { System.Diagnostics.Process.GetProcessById(int.Parse(match.Value)).Kill(); } Console.WriteLine("ERROR: {0}: [ {1} ]", e.Message, srcPath); } } } AddLogEntry(dstDirectoy + path, eventType, error); } } I checked everywhere in my program and whenever I use some file I use it in using block so even writing event to log (class for what I ommited since there is probably too much code already in post) wont lock the file, that is it shouldn't since all operations are using using statement block. I simply have no clue who's locking the file if not my program "copy" process from user through Windows or something else. Right now I have two possible "solutions" (I can't say they are clean solutions since they are hacks and as such not desireable). Since probably the problem is with fileType method (what else could lock the file?) I tried changing it to this, to simulate "blocking-until-ready-to-open" operation: fileType: private int fileType(string path) { FileStream fs = null; int ret = 0; bool run = true; if (Directory.Exists(path)) ret = 1; else { while (run) { try { fs = new FileStream(path, FileMode.Open); ret = 2; run = false; } catch (IOException) { } finally { if (fs != null) { fs.Close(); fs.Dispose(); } } } } return ret; } This is working as much as I could tell (test), but... it's hack, not to mention other deficients. The other "solution" I could try (I didn't test it yet) is using GC.Collect() somewhere at the end of fileType() method. Maybe even worse "solution" than previous one. Can someone pleas tell me, what on earth is locking the file, preventing it from opening and how can I fix that? What am I missing to see? Thanks in advance.

JNI String Corruption

- by Chris Dennett

Hi everyone, I'm getting weird string corruption across JNI calls which is causing problems on the the Java side. Every so often, I'll get a corrupted string in the passed array, which sometimes has existing parts of the original non-corrupted string. The C++ code is supposed to set the first index of the array to the address, it's a nasty hack to get around method call limitations. Additionally, the application is multi-threaded. remoteaddress[0]: 10.1.1.2:49153 remoteaddress[0]: 10.1.4.2:49153 remoteaddress[0]: 10.1.6.2:49153 remoteaddress[0]: 10.1.2.2:49153 remoteaddress[0]: 10.1.9.2:49153 remoteaddress[0]: {garbage here} java.lang.NullPointerException at kokuks.KKSAddress.<init>(KKSAddress.java:139) at kokuks.KKSAddress.createAddress(KKSAddress.java:48) at kokuks.KKSSocket._recvFrom(KKSSocket.java:963) at kokuks.scheduler.RecvOperation$1.execute(RecvOperation.java:144) at kokuks.scheduler.RecvOperation$1.execute(RecvOperation.java:1) at kokuks.KKSEvent.run(KKSEvent.java:58) at kokuks.KokuKS.handleJNIEventExpiry(KokuKS.java:872) at kokuks.KokuKS.handleJNIEventExpiry_fjni(KokuKS.java:880) at kokuks.KokuKS.runSimulator_jni(Native Method) at kokuks.KokuKS$1.run(KokuKS.java:773) at java.lang.Thread.run(Thread.java:717) remoteaddress[0]: 10.1.7.2:49153 The null pointer exception comes from trying to use the corrupt string. In C++, the address prints to standard out normally, but doing this reduces the rate of errors, from what I can see. The C++ code (if it helps): /* * Class: kokuks_KKSSocket * Method: recvFrom_jni * Signature: (Ljava/lang/String;[Ljava/lang/String;Ljava/nio/ByteBuffer;IIJ)I */ JNIEXPORT jint JNICALL Java_kokuks_KKSSocket_recvFrom_1jni (JNIEnv *env, jobject obj, jstring sockpath, jobjectArray addrarr, jobject buf, jint position, jint limit, jlong flags) { if (addrarr && env->GetArrayLength(addrarr) > 0) { env->SetObjectArrayElement(addrarr, 0, NULL); } jboolean iscopy; const char* cstr = env->GetStringUTFChars(sockpath, &iscopy); std::string spath = std::string(cstr); env->ReleaseStringUTFChars(sockpath, cstr); // release me! if (KKS_DEBUG) { std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << std::endl; } ns3::Ptr<ns3::Socket> socket = ns3::Names::Find<ns3::Socket>(spath); if (!socket) { std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << " socket not found for path!!" << std::endl; return -1; // not found } if (!addrarr) { std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << " array to set sender is null" << std::endl; return -1; } jsize arrsize = env->GetArrayLength(addrarr); if (arrsize < 1) { std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << " array too small to set sender!" << std::endl; return -1; } uint8_t* bufaddr = (uint8_t*)env->GetDirectBufferAddress(buf); long bufcap = env->GetDirectBufferCapacity(buf); uint8_t* realbufaddr = bufaddr + position; uint32_t remaining = limit - position; if (KKS_DEBUG) { std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << " bufaddr: " << bufaddr << ", cap: " << bufcap << std::endl; } ns3::Address aaddr; uint32_t mflags = flags; int ret = socket->RecvFrom(realbufaddr, remaining, mflags, aaddr); if (ret > 0) { if (KKS_DEBUG) std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << " addr: " << aaddr << std::endl; ns3::InetSocketAddress insa = ns3::InetSocketAddress::ConvertFrom(aaddr); std::stringstream ss; insa.GetIpv4().Print(ss); ss << ":" << insa.GetPort() << std::ends; if (KKS_DEBUG) std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << " addr: " << ss.str() << std::endl; jsize index = 0; const char *cstr = ss.str().c_str(); jstring jaddr = env->NewStringUTF(cstr); if (jaddr == NULL) std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << " jaddr is null!!" << std::endl; //jaddr = (jstring)env->NewGlobalRef(jaddr); env->SetObjectArrayElement(addrarr, index, jaddr); //if (env->ExceptionOccurred()) { // env->ExceptionDescribe(); //} } jint jret = ret; return jret; } The Java code (if it helps): /** * Pass an array of size 1 into remote address, and this will be set with * the sender of the packet (hax).

Stretch UL to fill the entire DIV

There is a similar post: Stretch horizontal ul to fit width of div But mine is a little bit tricky, as I have tried the above example but failed. My code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-… <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title></title> <script type='text/javascript' src='https://ajax.googleapis.com/ajax/li… <script> function mainmenu(){ $(" #nav ul ").css({display: "none"}); // Opera Fix $(" #nav li").hover(function(){ $(this).find('ul:first').css({visibi… "visible",display: "none"}).show(400); },function(){ $(this).find('ul:first').css({visibi… "hidden"}); }); } $(document).ready(function(){ mainmenu(); }); </script> <style> body{ font-size:0.85em; font-family:Verdana, Arial, Helvetica, sans-serif; } #nav, #nav ul{ margin:0; padding:0; list-style-type:none; list-style-position:outside; position:relative; line-height:1.5em; display: table; width: 100%; } #nav a{ display:block; padding:10px 15px 10px 15px; border:1px solid #fff; color:#fff; text-align: center; margin:0; text-decoration:none; background: #C34328; border-top:1px solid #EF593B; -moz-box-shadow:0px 3px 4px #591E12 inset; -webkit-box-shadow:0px 3px 4px #591E12 inset; -box-shadow:0px 3px 4px #591E12 inset; } #nav a:hover{ background-color:#fff; color:#333; } #nav li{ float:left; position:relative; } #nav ul { position:absolute; display:none; width:12em; top:3.2em; } #nav li ul a{ width:12em; height:auto; float:left; } #nav ul ul{ top:auto; } #nav li ul ul { left:12em; margin:0px 0 0 10px; } </style> </head> <body> <div style="width: 980px; border: 1px black solid;"> <ul id="nav"> <li><a href="#">Find a Doctor</a></li> <li><a href="#">Why Interfaith</a></li> <li><a href="#">For Patients & Visitors</a> <ul> <li><a href="#">3.1 jQuery</a></li> <li><a href="#">3.2 Mootools</a></li> <li><a href="#">3.3 Prototype</a></li> </ul> </li> <li><a href="#">Medical Services</a> <ul> <li><a href="#">Behavioral Health</a></li> <li><a href="#">Clinical Laboratory</a></li> <li><a href="#">Dentistry</a></li> <li><a href="#">Emergency</a></li> <li><a href="#">Gynecology</a></li> <li><a href="#">Medicine</a></li> <li><a href="#">Pastoral</a></li> <li><a href="#">Pediatrics</a></li> <li><a href="#">Physical Medicine & Rehab</a></li> </ul> </li> <li><a href="#">Medical Trainings</a> <ul> <li><a href="#">Medical Training</a></li> <li><a href="#">Behavioral Health</a></li> <li><a href="#">Predoctoral Externship</a></li> <li><a href="#">Podiatric Residency</a></li> <li><a href="#">Dental Residency</a></li> <li><a href="#">Pulmonary Medicine</a></li> </ul> </li> <li><a href="#">Contact</a></li> </ul> </div> </body> </html> Can someone tell me where I have to edit to complete the code?

Overlapping and Stacking in CSS

- by ApacheCode

Hello, I'm a programmer and learning new techniques in web development. I've ran into a problem if you could look at the link below. http://bailesslaw.com/Bailess_003/bailesHeader/header.html This example I made isnt fixed and it needs to be, which is becoming difficult. This looks fine on here, but when I put those layers on main website, index.html, place this code as the header, the banner moves in the documents position 0,0 . I need these boxes fixed, center page and I cannot get them to do that without messing up the layers order and content. Layer1-rotating images, js causes the rotation Layer2-blue triangle with backdrop effect overlapping layer 1, Layer 3-is a static image with a high z-index Below I including some code, the important part that needs 3 overlapped layers exactly matching in width and height, except it has to be fixed in center 780px wide. Code: <style rel="stylesheet" type="text/css"> div#layer1 { border: 1px solid #000; height: 200px; left: 0px; position: fixed; top: 0px; width: 780px; z-index: 1; } div#layer2 { border: 1px solid #000; height: 200px; left: 0px; position: absolute; top: 0px; width: 780px; z-index: 2; } div#layer3 { border: 1px solid #000000; height: 200px; left: 0px; position: absolute; top: 0px; width: 780px; z-index: 3; } </style> </head> <body class="oneColFixCtr"> <div id="container"> <div id="mainContent"> <div id="layer1"> </div> <div id="layer2"> <div class="slideshow"> <span id="rotating1"> <p class="rotating"> </p> </span> <span id="rotating2"> <p class="rotating"> </p> </span> <span id="rotating3"> <p class="rotating"> </p> </span> <span id="rotating4"> <p class="rotating"> </p> </span> </div> </div> <div id="layer3"> <table width="385" border="0"> <tr> <th width="81" scope="col">   </th> <th width="278" scope="col">   </th> <th width="12" scope="col">   </th> </tr> <tr> <td>   </td> <td> </td> <td>   </td> </tr> <tr> <td>   </td> <td>   </td> <td>   </td> </tr> </table> </div> </div>  </div> </body> </body> </html> CSS: @charset "utf-8"; CSS code: #rotating1 { height: 200px; width: 780px; } #rotating2 { height: 200px; width: 780px; } #rotating3 { height: 200px; width: 780px; } #main { background-repeat: no-repeat; height: 200px; width: 780px; z-index: 100; } #test { width: 780px; z-index: 2; } #indexContent { background-color: #12204d; background-repeat: no-repeat; height: 200px; width: 780px; z-index: 1; } #indexContent p { padding: .5em 2em .5em 2em; text-align: justify; text-indent: 2em; } .rotating { float: right; margin-top: 227px; text-indent: 0px !important; } .clearfix:after { clear: both; content: " "; display: block; font-size: 0; height: 0; visibility: hidden; } .clearfix { display: inline-block; } * html .clearfix { height: 1%; } .clearfix { display: block; }

addEventListener() isn't detecting KEY_UP nor KEY_DOWN

- by Zirenth

My full code is import flash.events.KeyboardEvent; import flash.events.Event; //init some variables var speedX = 0; var speedY = 0; msg.visible = false; var curLevel = 2; var level = new Array(); var flagVar; var won = false; //Adding level platforms for(var i = 0; i < numChildren; i++) { if(getChildAt(i) is platform) { level.push(getChildAt(i).getRect(this)); } if(getChildAt(i) is flag) { flagVar = getChildAt(i).getRect(this); } } //Checking key presses var kUp = false; var kDown = false; var kLeft = false; var kRight = false; var kSpace = false; stage.addEventListener(KeyboardEvent.KEY_DOWN, kD); stage.addEventListener(KeyboardEvent.KEY_UP, kU); function kD(k:KeyboardEvent) { trace("Key down - " + k.keyCode); if(k.keyCode == 32) { kSpace = true; } if(k.keyCode == 37 ) { kLeft = true; } if(k.keyCode == 38) { kUp = true; } if(k.keyCode == 39) { kRight = true; } } function kU(k:KeyboardEvent) { trace("Key up - " + k.keyCode); if(k.keyCode == 32) { kSpace = false; } if(k.keyCode == 37) { kLeft = false; } if(k.keyCode == 38) { kUp = false; } if(k.keyCode == 39) { kRight = false; } } addEventListener(Event.ENTER_FRAME, loopAround); function loopAround(e:Event) { //horizontal movement if(kLeft) { speedX = -10; } else if(kRight) { speedX = 10; } else { speedX *= 0.5; } player.x += speedX; //horizontal collision checks for(var i = 0; i < level.length; i++) { if(player.getRect(this).intersects(level[i])) { if(speedX > 0) { player.x = level[i].left - player.width; } if(speedX < 0) { player.x = level[i].right; } speedX = 0; } } //vertical movement speedY += 1; player.y += speedY; var jumpable = false; //Vertical collision for(i = 0; i < level.length; i++) { if(player.getRect(this).intersects(level[i])) { if(speedY > 0) { player.y = level[i].top - player.height; speedY = 0; jumpable = true; } if(speedY < 0) { player.y = level[i].bottom; speedY *= -0.5; } } } //JUMP! if((kUp || kSpace) && jumpable) { speedY=-20; } //Moving camera and other this.x = -player.x + (stage.stageWidth/2); this.y = -player.y + (stage.stageHeight/2); msg.x = player.x - (msg.width/2); msg.y = player.y - (msg.height/2); //Checking win if(player.getRect(this).intersects(flagVar)) { msg.visible = true; won = true; } //Check for next level request if(kSpace && won) { curLevel++; gotoAndStop(curLevel); won = false; } } The section in question is //Checking key presses var kUp = false; var kDown = false; var kLeft = false; var kRight = false; var kSpace = false; stage.addEventListener(KeyboardEvent.KEY_DOWN, kD); stage.addEventListener(KeyboardEvent.KEY_UP, kU); function kD(k:KeyboardEvent) { trace("Key down - " + k.keyCode); if(k.keyCode == 32) { kSpace = true; } if(k.keyCode == 37 ) { kLeft = true; } if(k.keyCode == 38) { kUp = true; } if(k.keyCode == 39) { kRight = true; } } function kU(k:KeyboardEvent) { trace("Key up - " + k.keyCode); if(k.keyCode == 32) { kSpace = false; } if(k.keyCode == 37) { kLeft = false; } if(k.keyCode == 38) { kUp = false; } if(k.keyCode == 39) { kRight = false; } } This was working fine last night, but today I moved it to a new keyframe and now it's not working. I'm not getting any errors (even if I debug). It just won't move the character or even show up in output. I'm still quite new to as3, so I don't really know what to do. Thanks in advance. Edit: After playing with it a bit, I've found out that the reason it's not working is due to the menu. The menu has a single button and two text elements, which are fine. The code that I'm using on the menu is this: import flash.events.MouseEvent; stop(); var format:TextFormat = new TextFormat(); format.size = 26; format.bold = true; playGameButton.setStyle("textFormat", format); stage.addEventListener(MouseEvent.CLICK, playGame); function playGame(e:MouseEvent) { if(e.target.name == "playGameButton") { gotoAndStop(2); } } If I use just gotoAndStop(2); it works fine, but with everything else it just goes to the second frame, and nothing else works after that. Edit #2: I've narrowed it down even farther to the if statement itself. if(e.target == playGameButton) if(e.target.name == "playGameButton") Both of those don't work. If I just remove the if statement all together it works perfectly fine.

A control with ID 'AdventureWorks3.mdf' could not be found What is causing this error? Here is my default.aspx file. I have configured GridView1 to use my AdventureWorks3.mdf file, stored in my App_Data folder.
