• similarity between strings - sql server 2005

  - by csetzkorn

  Hi, I am looking for a simple way (UDF?) to establish the similarity between strings. The SOUNDEX and DIFFERENCE function do not seem to do the job. Similarity should be based on number of characters in common (order matters). For example: Spiruroidea sp. AM-2008 and Spiruroidea gen. sp. AM-2008 should be recognised as similar. Any pointers would be very much appreciated. Thanks. Christian

• E_ACCESSDENIED on CoCreateInstance

  - by vucetica

  Here is a code snippet #include "stdafx.h" #include <tchar.h> #include <windows.h> #include <dshow.h> #include <ExDisp.h> int _tmain(int argc, _TCHAR* argv[]) { CoInitialize(NULL); HRESULT hr = S_OK; DWORD err = 0; // Try to create graph builder IGraphBuilder* pGraph = 0; hr = CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC_SERVER, IID_IGraphBuilder, (void**)&pGraph ); err = GetLastError(); // Here, hr is E_ACCESSDENIED // err is 5 (ERROR_ACCESS_DENIED) // Try to create capture graph builder (succeeds) ICaptureGraphBuilder2* pBuild = 0; hr = CoCreateInstance(CLSID_CaptureGraphBuilder2, NULL, CLSCTX_INPROC_SERVER, IID_ICaptureGraphBuilder2, (void **)&pBuild ); err = GetLastError(); // Here, hr is S_OK // err is 0 (ERROR_SUCCESS) // Try to create IWebBrowser (succeeds) IWebBrowser2* pBrowser = 0; hr = CoCreateInstance (CLSID_InternetExplorer, NULL, CLSCTX_LOCAL_SERVER, IID_IWebBrowser2, (LPVOID *)&pBrowser); err = GetLastError(); // Here, hr is S_OK // err is 0 (ERROR_SUCCESS) return 0; } I'm trying to create IFilterGraph, which fails with E_ACCESSDENIED. On the other hand, creating other directshow objects works ok. The same with some other COM objects (tried with IWebBrowser2 as an example). Any idea what can be the problem? Thanks!

• Passing an instantiated class to concrete class derived by Castle Windsor

  - by Tr1stan

  I have a system that I'm using to test some new architecture. I have the following setup (In MVC2 .Net - C Sharp): View < Controller < Service < Repository < DB I'm using Castle Windsor as my DI (IoC) controller, and this is working just fine in both the Service and Repo layers. However, I'm now at a point where I would like to pass an Entity Framework (DatabaseNameEntity) to the constructor to the Service, and then to the Repo, so that I have something similar to a Unit of Work pattern per request (This feels like what I'm trying to achieve anyway) - and I'm having trouble working out how this can be done using Castle Windsor. Am I going off on a silly tangent? Any pointers appreciated.

• Python Pari Library?

  - by silinter

  Pari/GP is an excellent library for functions relating to number theory. The problem is that there doesn't seem to be an up to date wrapper for python anywhere around, (pari-python uses an old version of pari) and I'm wondering if anyone knows of some other library/wrapper that is similar to pari or one that uses pari. I'm aware of SAGE, but it's far too large for my needs. GMPY is excellent as well, but there are some intrinsic pari functions that I miss, and I'd much rather use python than the provided GP environment. NZMATH, mpmath, scipy and sympy were all taken into consideration as well. On a related note, does anyone have any suggestions on loading the pari dll itself and using the functions contained in it? I've tried to very little success, other than loading it and learning about function pointers.

• Problems when I try to see databases in SQLite

  - by Sabau Andreea

  I created in code a database and two tables: static final String dbName="graficeCirculatie"; static final String ruteTable="Rute"; static final String colRuteId="RutaID"; static final String colRuta="Ruta"; static final String statiaTable="Statia"; static final String colStatiaID="StatiaID"; static final String colIdRuta="IdRuta"; static final String colStatia="Statia"; public DatabaseHelper(Context context) { super(context, dbName, null,33); } public void onCreate(SQLiteDatabase db) { // TODO Auto-generated method stub db.execSQL("CREATE TABLE " + statiaTable + " (" + colStatiaID + " INTEGER PRIMARY KEY , " + colIdRuta + " INTEGER, " + colStatia + " TEXT)"); db.execSQL("CREATE TABLE " + ruteTable + "(" + colRuteId + " INTEGER PRIMARY KEY AUTOINCREMENT, " + colRuta + " TEXT);"); InsertDepts(db); } void InsertDepts(SQLiteDatabase db) { ContentValues cv = new ContentValues(); cv.put(colRuteId, 1); cv.put(colRuta, "Expres8"); db.insert(ruteTable, colRuteId, cv); cv.put(colRuteId, 2); cv.put(colRuta, "Expres2"); db.insert(ruteTable, colRuteId, cv); cv.put(colRuteId, 3); cv.put(colRuta, "Expres3"); db.insert(ruteTable, colRuteId, cv); } Now I want to see tables inputs from command line.

• What's the best way to normalize scores for ranking things?

  - by beagleguy

  hi all, I'm curious how to do normalizing of numbers for a ranking algorithm let's say I want to rank a link based on importance and I have two columns to work with so a table would look like url | comments | views now I want to rank comments higher than views so I would first think to do comments*3 or something to weight it, however if there is a large view number like 40,000 and only 4 comments then the comments weight gets dropped out. So I'm thinking I have to normalize those scores down to a more equal playing field before I can weight them. Any ideas or pointers to how that's usually done? thanks

• Sending multi-part email from Google App Engine using Spring's JavaMailSender fails

  - by hleinone

  It works without the multi-part (modified from the example in Spring documentation): final MimeMessagePreparator preparator = new MimeMessagePreparator() { public void prepare(final MimeMessage mimeMessage) throws Exception { final MimeMessageHelper message = new MimeMessageHelper( mimeMessage); message.setTo(toAddress); message.setFrom(fromAddress); message.setSubject(subject); final String htmlText = FreeMarkerTemplateUtils .processTemplateIntoString(configuration .getTemplate(htmlTemplate), model); message.setText(htmlText, true); } }; mailSender.send(preparator); But once I change it to: final MimeMessagePreparator preparator = new MimeMessagePreparator() { public void prepare(final MimeMessage mimeMessage) throws Exception { final MimeMessageHelper message = new MimeMessageHelper( mimeMessage, true); ... message.setText(plainText, htmlText); } }; mailSender.send(preparator); I get: Failed message 1: javax.mail.MessagingException: Converting attachment data failed at com.google.appengine.api.mail.stdimpl.GMTransport.sendMessage(GMTransport.java:231) at org.springframework.mail.javamail.JavaMailSenderImpl.doSend(JavaMailSenderImpl.java:402) ... This is especially difficult since the GMTransport is proprietary Google class and no sources are available, which would make it a bit easier to debug. Anyone have any ideas what to try next?

• How to Bind Data and manipulate it in a GridView with MVP

  - by DotNetDan

  I am new to the whole MVP thing and slowly getting my head around it all. The a problem I am having is how to stay consistent with the MVP methodology when populating GridViews (and ddls, but we will tackle that later). Is it okay to have it connected straight to an ObjectDataSourceID? To me this seems wrong because it bypasses all the separation of concerns MVP was made to do. So, with that said, how do I do it? How do I handle sorting (do I send over handler events to the presentation layer, if so how does that look in code)? Right now I have a GridView that has no sorting. Code below. ListCustomers.aspx.cs: public partial class ListCustomers : System.Web.UI.Page, IlistCustomer { protected void Page_Load(object sender, EventArgs e) { //On every page load, create a new presenter object with //constructor recieving the // page's IlistCustomer view ListUserPresenter ListUser_P = new ListUserPresenter(this); //Call the presenter's PopulateList to bind data to gridview ListUser_P.PopulateList(); } GridView IlistCustomer.UserGridView { get { return gvUsers; } set { gvUsers = value; } } } Interface ( IlistCustomer.cs): is this bad sending in an entire Gridview control? public interface IlistCustomer { GridView UserGridView { set; get; } } The Presenter (ListUserPresenter.cs): public class ListUserPresenter { private IlistCustomer view_listCustomer; private GridView gvListCustomers; private DataTable objDT; public ListUserPresenter( IlistCustomer view) { //Handle an error if an Ilistcustomer was not sent in) if (view == null) throw new ArgumentNullException("ListCustomer View cannot be blank"); //Set local IlistCustomer interface view this.view_listCustomer = view; } public void PopulateList() { //Fill local Gridview with local IlistCustomer gvListCustomers = view_listCustomer.UserGridView; // Instantiate a new CustomerBusiness object to contact database CustomerBusiness CustomerBiz = new CustomerBusiness(); //Call CustomerBusiness's GetListCustomers to fill DataTable object objDT = CustomerBiz.GetListCustomers(); //Bind DataTable to gridview; gvListCustomers.DataSource = objDT; gvListCustomers.DataBind(); } }

• Defend zero-based arrays

  - by DrJokepu

  A question asked here recently reminded me of a debate I had not long ago with a fellow programmer. Basically he argued that zero-based arrays should be replaced by one-based arrays since arrays being zero based is an implementation detail that originates from the way arrays and pointers and computer hardware work, but these sort of stuff should not be reflected in higher level languages. Now I am not really good at debating so I couldn't really offer any good reasons to stick with zero-based arrays other than they sort of feel like more appropriate. I am really interested in the opinions of other developers, so I sort of challenge you to come up with reasons to stick with zero-based arrays!

Wat is happening here? Am I doing something invalid? gcc version is 4.4.3 if relevant. Thanks for your attention.

• How do I print an HTML document from a web service?

  - by Chris Marasti-Georg

  I want to print HTML from a C# web service. The Web Browser control is overkill, and does not function well in a service-environment, nor does it function well on a system with very tight security constraints. Is there any sort of free .NET library that will support the printing of a basic HTML page? Here is the code I have so far, that is not running properly. public void PrintThing(string document) { if (Thread.CurrentThread.GetApartmentState() != ApartmentState.STA) { Thread thread = new Thread((ThreadStart) delegate { PrintDocument(document); }); thread.SetApartmentState(ApartmentState.STA); thread.Start(); } else { PrintDocument(document); } } protected void PrintDocument(string document) { WebBrowser browser = new WebBrowser(); browser.DocumentText = document; while (browser.ReadyState != WebBrowserReadyState.Complete) { Application.DoEvents(); } browser.Print(); } This works fine when called from UI-type threads, but nothing happens when called from a service-type thread. Changing Print() to ShowPrintPreviewDialog() yields the following IE script error: Error: 'dialogArguments.___IE_PrintType' is null or not an object URL: res://ieframe.dll/preview.dlg And a small empty print preview dialog appears.

• stdexcept On Android

  - by David R.

  I'm trying to compile SoundTouch on Android. I started with this configure line: ./configure CPPFLAGS="-I/Volumes/android-build/mydroid/development/ndk/build/platforms/android-3/arch-arm/usr/include/" LDFLAGS="-Wl,-rpath-link=/Volumes/android-build/mydroid/development/ndk/build/platforms/android-3/arch-arm/usr/lib -L/Volumes/android-build/mydroid/development/ndk/build/platforms/android-3/arch-arm/usr/lib -nostdlib -lc" --host=arm-eabi --enable-shared=yes CFLAGS="-nostdlib -O3 -mandroid" host_alias=arm-eabi --no-create --no-recursion Because the Android NDK targets ARM, I also had to change the Makefile to remove the -msse2 flags to progress. When I run 'make', I get: /bin/sh ../../libtool --tag=CXX --mode=compile arm-eabi-g++ -DHAVE_CONFIG_H -I. -I../../include -I../../include -I/Volumes/android-build/mydroid/development/ndk/build/platforms/android-3/arch-arm/usr/include/ -O3 -fcheck-new -I../../include -g -O2 -MT FIRFilter.lo -MD -MP -MF .deps/FIRFilter.Tpo -c -o FIRFilter.lo FIRFilter.cpp libtool: compile: arm-eabi-g++ -DHAVE_CONFIG_H -I. -I../../include -I../../include -I/Volumes/android-build/mydroid/development/ndk/build/platforms/android-3/arch-arm/usr/include/ -O3 -fcheck-new -I../../include -g -O2 -MT FIRFilter.lo -MD -MP -MF .deps/FIRFilter.Tpo -c FIRFilter.cpp -o FIRFilter.o FIRFilter.cpp:46:21: error: stdexcept: No such file or directory FIRFilter.cpp: In member function 'virtual void soundtouch::FIRFilter::setCoefficients(const soundtouch::SAMPLETYPE*, uint, uint)': FIRFilter.cpp:177: error: 'runtime_error' is not a member of 'std' FIRFilter.cpp: In static member function 'static void* soundtouch::FIRFilter::operator new(size_t)': FIRFilter.cpp:225: error: 'runtime_error' is not a member of 'std' make[2]: *** [FIRFilter.lo] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all-recursive] Error 1 This isn't very surprising, since the -nostdlib flag was required. Android seems to have neither stdexcept nor stdlib. How can I get past this block of compiling SoundTouch? At a guess, there may be some flag I don't know about that I should use. I could refactor the code not to use stdexcept. There may be a way to pull in the original stdexcept source and reference that. I might be able to link to a precompiled stdexcept library.

• FLEX: the custom component is still a Null Object when I invoke its method

  - by Patrick

  Hi, I've created a custom component in Flex, and I've created it from the main application with actionscript. Successively I invoke its "setName" method to pass a String. I get the following run-time error (occurring only if I use the setName method): TypeError: Error #1009: Cannot access a property or method of a null object reference. I guess I get it because I'm calling to newUser.setName method from main application before the component is completely created. How can I ask actionscript to "wait" until when the component is created to call the method ? Should I create an event listener in the main application waiting for it ? I would prefer to avoid it if possible. Here is the code: Main app ... newUser = new userComp(); //newUser.setName("name"); Component: <?xml version="1.0" encoding="utf-8"?> <mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml" width="100" height="200" > <mx:Script> <![CDATA[ public function setName(name:String):void { username.text = name; } public function setTags(Tags:String):void { } ]]> </mx:Script> <mx:HBox id="tagsPopup" visible="false"> <mx:LinkButton label="Tag1" /> <mx:LinkButton label="Tag2" /> <mx:LinkButton label="Tag3" /> </mx:HBox> <mx:Image source="@Embed(source='../icons/userIcon.png')"/> <mx:Label id="username" text="Nickname" visible="false"/> </mx:VBox> thanks

• Logging Mechanism using memory mapping technique

  - by Tushar

  Just create a mapping of the file of the required size (CreateFileMapping or mmap), write the lines in the buffer and start over when the maximum number is reached. -- Your answer for write-a-circular-file-in-c. I am also writing the LogWriter module. In this caase i am mapping the whole file to the memory using mmap(). I am maintaining the Read and Write pointers.I want to write the log to the file in append mode. Then when logger service is started first time it writes it appends the logs. But when system gets shutdown next time when i run the service it doesn't append the data at the end. I want to maintain the write and read offsets even if system shut down.How to achieve this ..? How to find the how much data is written to the log file. ??

• combining two select statements to return one result

  - by DalivDali

  I need to combine the results for two select queries from two view tables, from which I am performing calculations. Perhaps there is an easier way to perform a query using if...else - any pointers? Essentially I need to divide everything by 'ar.time_ratio' under the condition in sql query 1, and ignore that for query 2. SELECT gs.traffic_date, gs.domain_group, gs.clicks/ar.time_ratio as 'Scaled_clicks', gs.visitors/ar.time_ratio as 'scaled_visitors', gs.revenue/ar.time_ratio as 'scaled_revenue', (gs.revenue/gs.clicks)/ar.time_ratio as 'scaled_average_cpc', (gs.clicks)/(gs.visitors)/ar.time_ratio as 'scaled_ctr', gs.average_rpm/ar.time_ratio as 'scaled_rpm', (((gs.revenue)/(gs.visitors))/ar.time_ratio)*1000 as "Ecpm" FROM group_stats gs, v_active_ratio ar WHERE ar.group_id=gs.domain_group and SELECT gs.traffic_date, gs.domain_group, gs.clicks, gs.visitors, gs.revenue, (gs.revenue/gs.clicks) as 'average_cpc', (gs.clicks)/(gs.visitors) as 'average_ctr', gs.average_rpm, ((gs.revenue)/(gs.visitors))*1000 as "Ecpm" FROM group_stats gs, v_active_ratio ar where not ar.group_id=gs.domain_group

• If statement is ignored

  - by user2898120

  I am making a simple matchmaker as a learning project in JAVA. My program so far just asks a few questions, but I wanted to do gender specific questions, so I asked for their sex (m or f) and then attempted to add a message that only showed if sex was m. The dialog should say "well done, you are male!". Else it restarts method. Every time, no matter what I type it restarts the program. Here is my code: import javax.swing.JOptionPane; public class Main { public static void main(String[] args){ setVars(); } public static void setVars(){ String name = JOptionPane.showInputDialog(null, "What is your name?"); String sAge = JOptionPane.showInputDialog(null, "What is your age?"); String sex = JOptionPane.showInputDialog(null, "What is your sex?\n(Enter m or f)"); if (sex == "m"){ JOptionPane.showMessageDialog(null, "Well done, you are male.\nKeep Going!"); } int age = Integer.parseInt(sAge); String chars = JOptionPane.showInputDialog(null, "Name three charectaristics"); } }

• Removing a view from it's superview causes memory error - why?

  - by mystify

  Xcode is throwing an error at me: malloc: * error for object 0x103f000: pointer being freed was not allocated * set a breakpoint in malloc_error_break to debug I tracked down the code until a line where I do this: - (void)inputValueCommitted:(NSString *)animationID finished:(BOOL)finished context:(void *)context { // retainCount of myView is 2! (one for the retain-property, one for beeing a subview) [self.myView removeFromSuperview]; // ERROR-LINE !! self.myView = nil; } When I remove that errorful line, the error is gone. So in conclusion: I can't get rid of my view! It's an UIImageView with nothing else inside, just showing an image. What I do is this: I create an UIView Animation Block, create that UIImageView, assign it to an retain-property with self.myView = ..., and after the animation is done, I just want to get rid of that view. So I remove it from it's superview and then set my property to nil, which lets it go away - in theory. Did anyone else encounter such issues? iPhone SDK 3.0.

• Datagridview Winforms Add or Delete Rows in Edit Mode with Collection Binding

  - by user630548

  In my datagridview, I bind a List of objects named 'ProductLine'. But unfortunately with this approach I cannot 'Add' or 'Delete' rows to the datagridview in edit mode. When I create a fresh new order I can Add or Delete rows but once I save it and try to open it in Edit then it doesn't let me 'Add' or 'Delete' (via keyboard). Any idea? Here is the code for this: If it is a fresh Order then I do something like this: private void Save(){ for (int i = 0; i <= dtgProdSer.RowCount - 1; i++) { if ((itemList != null) && (itemList.Count > i)) productLine = itemList[i]; else productLine = new ProductLine(); productLine.Amount = Convert.ToDouble(dataGridViewTextBoxCell.Value); } } And if it is an Edit then in the Form_Load I check ProductId is NON Zero then I do the following: private void fillScreen{ dtgProdSer.DataSource = itemList; } But with this I cannot Add or Delete Rows in Edit mode. Any advise is greatly appreciated.

• Getting a char array from a vector<int>?

  - by Legend

  I am trying to pass a value from C++ to TCL. As I cannot pass pointers without the use of some complicated modules, I was thinking of converting a vector to a char array and then passing this as a null terminated string (which is relatively easy). I have a vector as follows: 12, 32, 42, 84 which I want to convert into something like: "12 32 42 48" The approach I am thinking of is to use an iterator to iterate through the vector and then convert each integer into its string representation and then add it into a char array (which is dynamically created initially by passing the size of the vector). Is this the right way or is there a function that already does this?

• UITabBarControllerDelegate compare value of viewController

  - by T9

  I have a tabBar with 4 tabs on it, and I want to perform some action when a specific tab is selected, so I have uncommented the UITabBarControllerDelegate in the xxAppDelegate.m I also wanted to see the value that was being sent logged in the console - in order to test my "if" statement. However this is where I got stumped. // Optional UITabBarControllerDelegate method - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { NSLog(@"%@", viewController); } The console dutifully logged any selected controller that had been selected, but in this particular format: <MyViewController: 0x3b12950> Now, I wasn't expecting the square brackets or the colon or the Hex. So my question is how do I format my IF statement? This is what I thought would work but I get an error mentioned further down. // Optional UITabBarControllerDelegate method - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { NSLog(@"%@", viewController); if (viewController == MyViewController) { //do something nice here … }; } ... The error is "Expected expression before 'MyViewController'" Anyone know how I should be doing this?

• How do I animate UserControl objects using Storyboard and DoubleAnimation?

  - by Neo

  In my WPF application, I have a Canvas object that contains some UserControl objects. I wish to animate the UserControl objects within the Canvas using DoubleAnimation so that they go from the right of the Canvas to the left of the Canvas. This is how I have done it so far (by passing the UserControl objects into the function): private void Animate(FrameworkElement e) { DoubleAnimation ani = new DoubleAnimation() { From = _container.ActualWidth, To = 0.0, Duration = new Duration(new TimeSpan(0, 0, 10), TargetElement = e }; TranslateTransform trans = new TranslateTransform(); e.RenderTransform = trans; trans.BeginAnimation(TranslateTransform.XProperty, ani, HandoffBehavior.Compose); } However, this doesn't allow me to pause the animation, so I have considered using a Storyboard instead to do this, but I'm not sure how to implement this. This has been my attempt so far: private void Animate(FrameworkElement e) { DoubleAnimation ani = new DoubleAnimation() { From = _container.ActualWidth, To = 0.0, Duration = new Duration(new TimeSpan(0, 0, 10), TargetElement = e }; Storyboard stb = new Storyboard(); Storyboard.SetTarget(ani, e); Storyboard.SetTargetProperty(ani, "Left"); stb.Children.Add(ani); stb.Begin(); } Of course, this fails as UserControl doesn't have a Left property. How can I achieve what I'm after? Thanks.

• Text editing best practices (with tags, etc.)

  - by Ron

  Hi there, I want to create a text field with some text, that is styled with tags. Think of MS Word, some ext is bold, some is a headline, etc. The tags that style the text are not visible to the user, he just sees the text in bold. How do I preserve these tags? I mean when I backspace over the closing bold-tag, for example, how do I preserve that and prevent that the rest of the text is now bold until the end? I guess this is a pretty basic question for experiences programmers. Are there any algorithms or best practices? This problem surely has been solved before, any pointers? (If this is of any concern, I develop for the iPhone OS and the text field will be a UITextView, but my question is more general I guess.) Thanks in advance!

• Is it possible to resize a SpriteAsset without adding it to the display list?

  - by Sophistifunk

  Hi guys, I have an embedded image asset (with a scale9 grid), and I'm trying to get the bitmapdata when it's resized, but I can't seem to do this without adding it to the display list. I try this: spriteAsset.setActualSize(w,h); spriteAsset.width = w; bmd.draw(spriteAsset); But when I then draw out the bitmapdata with graphics.beginBitmapFill(), I just get the original un-stretched image. Any pointers? Or do I need to take 9 separate BitmapData images and make 9 separate bitmap fills? Cheers, -Josh

• Java Stop Server Thread

  - by ikurtz

  the following code is server code in my app: private int serverPort; private Thread serverThread = null; public void networkListen(int port){ serverPort = port; if (serverThread == null){ Runnable serverRunnable = new ServerRunnable(); serverThread = new Thread(serverRunnable); serverThread.start(); } else { } } public class ServerRunnable implements Runnable { public void run(){ try { //networkConnected = false; //netMessage = "Listening for Connection"; //networkMessage = new NetworkMessage(networkConnected, netMessage); //setChanged(); //notifyObservers(networkMessage); ServerSocket serverSocket = new ServerSocket(serverPort, backlog); commSocket = serverSocket.accept(); serverSocket.close(); serverSocket = null; //networkConnected = true; //netMessage = "Connected: " + commSocket.getInetAddress().getHostAddress() + ":" + //commSocket.getPort(); //networkMessage = new NetworkMessage(networkConnected, netMessage); //setChanged(); //notifyObservers(networkMessage); } catch (IOException e){ //networkConnected = false; //netMessage = "ServerRunnable Network Unavailable"; //System.out.println(e.getMessage()); //networkMessage = new NetworkMessage(networkConnected, netMessage); //setChanged(); //notifyObservers(networkMessage); } } } The code sort of works i.e. if im attempting a straight connection both ends communicate and update. The issue is while im listening for a connection if i want to quit listening then the server thread continues running and causes problems. i know i should not use .stop() on a thread so i was wondering what the solution would look like with this in mind? EDIT: commented out unneeded code.

• Default template parameters with forward declaration

  - by Seth Johnson

  Is it possible to forward declare a class that uses default arguments without specifying or knowing those arguments? For example, I would like to declare a boost::ptr_list< TYPE > in a Traits class without dragging the entire Boost library into every file that includes the traits. I would like to declare namespace boost { template<class T> class ptr_list< T >; }, but that doesn't work because it doesn't exactly match the true class declaration: template < class T, class CloneAllocator = heap_clone_allocator, class Allocator = std::allocator<void*> > class ptr_list { ... }; Are my options only to live with it or to specify boost::ptr_list< TYPE, boost::heap_clone_allocator, std::allocator<void*> in my traits class? (If I use the latter, I'll also have to forward declare boost::heap_clone_allocator and include <memory>, I suppose.) I've looked through Stroustrup's book, SO, and the rest of the internet and haven't found a solution. Usually people are concerned about not including STL, and the solution is "just include the STL headers." However, Boost is a much more massive and compiler-intensive library, so I'd prefer to leave it out unless I absolutely have to.
