• Mysql latin1 turkish data and delphi 2010 utf8

  - by sabri.arslan

  Hello, I have tables collating latin1_general_ci and have turkish character values. And i can use this data on delphi 7+zeos with no problem. but i want to upgrade my delphi to 2010 version but zeos too slow as i saw. so i want to use odbc+ado or dbexpress solution. dbexpress solution works fine , display my data as entered and write as entered table without any change to column charset. but dbexpress has problems as i saw. for example when i select * from table which has column types as varchar,decimal,int,tinyint,text give av errors on xp systems. vista and 7 does not give any error and work fine(not fully tested). ado solution(dbgo) works fine but its not show my data as entered.its want everything be utf. but i don't want to convert my data to utf before test everything. how can i see my data as entered and write client side utf and store latin1(as zeos or dbexpress do). i was tried many other options. eg. mysql side collation and charset parameters. sorry for my bad english. i hope someone understand me. thanks.

• xcode 5.1: libCordova.a architecture problems

  - by inorganik

  Yesterday (3/10/14) when iOS 7.1 was released I also upgraded to Xcode 5.1 and found that my PhoneGap/Cordova project would no longer compile to my iPhone 5s. I also upgraded Cordova to the most recent release: v 3.4.0-0.1.3. I have read many different solutions on SO that relate so changing active architectures and building only active architectures, and none of them work. So here's what I've tried and the errors I get. Initially I got the error: missing required architecture arm64 in file <long file path omitted> libCordova.a Undefined symbols for architecture arm64 So I tried the following. I selected the CordovaLib sub-project in my project, and in both the project and target, I went to Build Settings under Architectures and made sure that arm64 was not included in any of the Debug or Release architectures. At this time Build Active Architecture Only is set to "Yes". That resulted in the following error: file was built for archive which is not the architecture being linked (armv7): <long file path omitted> libCordova.a Undefined symbols for architecture armv7 Setting Build Active Architecture Only to "No", the error again becomes: missing required architecture arm64 in file <long file path omitted> libCordova.a Undefined symbols for architecture arm64 I'm not sure what else to try. The project's architecture settings only includes the key "Base SDK" which is set to iOS 7.1. The project's target does not have architectures settings. Anyway I'm fairly certain the problem lies with the embedded CordovaLib sub-project. What can I do to make this thing compile to my device successfully? Update: same issue on Apache's Jira: https://issues.apache.org/jira/browse/CB-6223

• Configuring 32-Bit ASP.NET Application on a 64-Bit IIS Server

  - by Tim

  Hello, I’m trying to install a 32-bit ASP.NET application onto a 64-bit IIS server running on Windows Server 2008. This is a clean installation of the operating system with no other applications installed. As a prerequisite for our installation, we run the 32-bit version of aspnet_regiis –i It fails with the following message: The error indicates that IIS is not installed on the machine. Please install IIS before using this tool. Additionally: IIS is definitely installed. The 64 bit version of aspnet_regiis runs cleanly without warnings. “Enable 32 bit applications” is set to True in the DefaultAppPool’s Advanced Settings. The IIS Metabase and IIS 6 configuration compatibility” component is installed. We have a test VM where this error occurs as well as test VM where both the 32 bit and 64 bit versions of aspnet_regiis run without errors. We've had no luck distinguishing the differences between the two test VMs. We have struggled with this issue for several days to no avail. Any suggestions would be greatly appreciated!

• Setting up DrJava to work through Friedman / Felleisen "A Little Java"

  - by JDelage

  All, I'm going through the Friedman & Felleisen book "A Little Java, A Few Patterns". I'm trying to type the examples in DrJava, but I'm getting some errors. I'm a beginner, so I might be making rookie mistakes. Here is what I have set-up: public class ALittleJava { //ABSTRACT CLASS POINT abstract class Point { abstract int distanceToO(); } class CartesianPt extends Point { int x; int y; int distanceToO(){ return((int)Math.sqrt(x*x+y*y)); } CartesianPt(int _x, int _y) { x=_x; y=_y; } } class ManhattanPt extends Point { int x; int y; int distanceToO(){ return(x+y); } ManhattanPt(int _x, int _y){ x=_x; y=_y; } } } And on the main's side: public class Main{ public static void main (String [] args){ Point y = new ManhattanPt(2,8); System.out.println(y.distanceToO()); } } The compiler cannot find the symbols Point and ManhattanPt in the program. If I precede each by ALittleJava., I get another error in the main, i.e., an enclosing instance that contains ALittleJava.ManhattanPt is required I've tried to find ressources on the 'net, but the book must have a pretty confidential following and I couldn't find much. Thank you all. JDelage

• using ontouch to zoom in

• Academic question: typename

  - by Arman

  Hi, recently I accounted with a "simple problem" of porting code from VC++ to gcc/intel. The code is compiles w/o error on VC++: #include <vector> using std::vector; template <class T> void test_vec( std::vector<T> &vec) { typedef std::vector<T> M; /*==> add here typename*/ M::iterator ib=vec.begin(),ie=vec.end(); }; int main() { vector<double> x(100, 10); test_vec<double>(x); return 0; } then with g++ we have some unclear errors: g++ t.cpp t.cpp: In function 'void test_vec(std::vector<T, std::allocator<_CharT> >&)': t.cpp:13: error: expected `;' before 'ie' t.cpp: In function 'void test_vec(std::vector<T, std::allocator<_CharT> >&) [with T = double]': t.cpp:18: instantiated from here t.cpp:12: error: dependent-name 'std::M::iterator' is parsed as a non-type, but instantiation yields a type t.cpp:12: note: say 'typename std::M::iterator' if a type is meant If we add typename before iterator the code will compile w/o pb. If it is possible to make a compiler which can understand the code written in the more "natural way", then for me is unclear why we should add typename? Which rules of "C++ standards"(if there are some) will be broken if we allow all compilers to use without "typename"? kind regards Arman.

• How to print the address an ada access variable points to?

  - by georg

  I want to print the address of an access variable (pointer) for debugging purposes. type Node is private; type Node_Ptr is access Node; procedure foo(n: in out Node_Ptr) is package Address_Node is new System.Address_To_Access_Conversions(Node); use Address_Node; begin Put_Line("node at address " & System.Address_Image(To_Address(n))); end foo; Address_Image returns the string representation of an address. System.Address_To_Access_Conversions is a generic package to convert between addresses and access types (see ARM 13.7.2), defined as follows: generic type Object(<>) is limited private; package System.Address_To_Access_Conversions is -- [...] type Object_Pointer is access all Object; -- [...] function To_Address(Value : Object_Pointer) return Address; -- [...] end System.Address_To_Access_Conversions; gnat gives me the following errors for procedure foo defined above: expected type "System.Address_To_Access_Conversions.Object_Pointer" from instance at line... found type "Node_Ptr" defined at ... Object_Pointer ist definied as access all Object. From my understanding the type Object is Node, therefore Object_Ptr is access all Node. What is gnat complaining about? I guess my understanding of Ada generics is flawed and I am not using System.Address_To_Access_Conversions correctly. EDIT: I compiled my code with "gnatmake -gnatG" to see the generic instantiation: package address_node is subtype btree__clear__address_node__object__2 is btree__node; type btree__clear__address_node__object_pointer__2 is access all btree__clear__address_node__object__2; function to_address (value : btree__clear__address_node__object_pointer__2) return system__address; end address_node; btree__node is the mangled name of the type Node as defined above, so I really think the parameter type for to_address() is correct, yet gnat is complaining (see above).

• PLKs and Web Service Software Factory

  - by Nix

  We found a bug in Web Service Software Factory a description can be found here. There has been no updates on it so we decided to download the code and fix it ourself. Very simple bug and we patched it with maybe 3 lines of code. However* we have now tried to repackage it and use it and are finding that this is seemingly an impossible process. Can someone please explain to me the process of PLKs? I have read all about them but still don't understand what is really required to distribute a VS package. I was able to get it to load and run using a PLK obtained from here, but i am assuming that you have to be a partner to get a functional PLK that will be recognized on other peoples systems? Every time i try and install this on a different computer I get a "Package Load Failure". Is the reason I am getting errors because I am not using a partner key? Is there any other way around this? For instance is there any way we can have an "internal" VS package that we can distribute? Edit Files I had to change to get it to work. First run devenv PostInstall.proj Generate your plks and replace ##Package PLK## (.resx files) --Just note that package version is not the class name but is "Web Service Software Factory: Modeling Edition" -- And you need to remove the new lines from the key ProductDefinitionRegistryFragment.wxi line 1252(update version to whatever version you used in plk) Uncomment all // [VSShell::ProvideLoadKey("Standard", Constant in .tt files.

• Can Sql Server 2005 Pivot table have nText passed into it?

  - by manemawanna

  Right bit of a simple question can I input nText into a pivot table? (SQL Server 2005) What I have is a table which records the answers to a questionnaire consisting of the following elements for example: UserID QuestionNumber Answer Mic 1 Yes Mic 2 No Mic 3 Yes Ste 1 Yes Ste 2 No Ste 3 Yes Bob 1 Yes Bob 2 No Bob 3 Yes With the answers being held in nText. Anyway what id like a Pivot table to do is: UserID 1 2 3 Mic Yes No Yes Ste Yes No Yes Bob Yes No Yes I have some test code, that creates a pivot table but at the moment it just shows the number of answers in each column (code can be found below). So I just want to know is it possible to add nText to a pivot table? As when I've tried it brings up errors and someone stated on another site that it wasn't possible, so I would like to check if this is the case or not. Just for further reference I don't have the opportunity to change the database as it's linked to other systems that I haven't created or have access too. Heres the SQL code I have at present below: DECLARE @query NVARCHAR(4000) DECLARE @count INT DECLARE @concatcolumns NVARCHAR(4000) SET @count = 1 SET @concatcolumns = '' WHILE (@count <=52) BEGIN IF @COUNT > 1 AND @COUNT <=52 SET @concatcolumns = (@concatcolumns + ' + ') SET @concatcolumns = (@concatcolumns + 'CAST ([' + CAST(@count AS NVARCHAR) + '] AS NVARCHAR)') SET @count = (@count+1) END DECLARE @columns NVARCHAR(4000) SET @count = 1 SET @columns = '' WHILE (@count <=52) BEGIN IF @COUNT > 1 AND @COUNT <=52 SET @columns = (@columns + ',') SET @columns = (@columns + '[' + CAST(@count AS NVARCHAR) + '] ') SET @count = (@count+1) END SET @query = ' SELECT UserID, ' + @concatcolumns + ' FROM( SELECT UserID, QuestionNumber AS qNum from QuestionnaireAnswers where QuestionnaireID = 7 ) AS t PIVOT ( COUNT (qNum) FOR qNum IN (' + @columns + ') ) AS PivotTable' select @query exec(@query)

• Debugging NSoperation BAD ACCESS within graphics context

  - by Joe

  I tried everything to debug this one but I can't get to the bottom of it. This code lives in a subclass of NSOperation which is processed from a queue: (borders is an ivar NSArray containing 5 UIimage objects) NSMutableArray *images = [[NSMutableArray alloc] init]; for (unsigned i = 0; i < 5; i++) { CGSize size = CGSizeMake(60, 60); UIGraphicsBeginImageContext(size); CGPoint thumbPoint = CGPointMake(6, 6); [controller.image drawAtPoint:thumbPoint]; CGPoint borderPoint = CGPointMake(0, 0); [[borders objectAtIndex:i] drawAtPoint:borderPoint]; [images addObject:UIGraphicsGetImageFromCurrentImageContext()]; UIGraphicsEndImageContext(); } [images release]; The code works fine most of the time but when I push the iphone by access subviews and pressing lots of buttons on the UI I either get this exception which is trapped by the operation: Exception Load view: *** -[NSCFArray insertObject:atIndex:]: attempt to insert nil or I get this: Program received signal: “EXC_BAD_ACCESS”. The exception is caused because UIGraphicsGetImageFromCurrentImageContext() return nil. I don't know how to debug the EXC_BAD_ACCESS but I'm guessing that this error (in fact both of these errors) is caused by low memory. The debugger stops at the line: [controller.image drawAtPoint:thumbPoint]; As I mentioned I've trapped the exception so I can live with that but the EXC_BAD_ACCESS is more serious. IF this is memory related how can I tell and is it possible to increase the memory available to NSOperation?

  Right. So I have an app widget. It has 4 buttons, one one of the buttons I want it to show me the current location of the user on the map. So - I make a new activity as below: package com.android.driverwidget; import java.util.List; import android.os.Bundle; import com.google.android.maps.MapActivity; import com.google.android.maps.MapController; import com.google.android.maps.MapView; import com.google.android.maps.MyLocationOverlay; import com.google.android.maps.Overlay; public class MyLocation extends MapActivity{ public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); MapView myMapView = (MapView)findViewById(R.id.mapview); MapController mapController = myMapView.getController(); List<Overlay> overlays = myMapView.getOverlays(); MyLocationOverlay myLocationOverlay = new MyLocationOverlay(this, myMapView); overlays.add(myLocationOverlay); myLocationOverlay.enableMyLocation(); } protected boolean isRouteDisplayed() { return false; } } And then I added the appropriate uses library line to the manifest <activity android:name=".MyLocation" android:label="myLocation"> </activity> <uses-library android:name="com.google.android.maps" /> Ok yet - when I run the app the following errors occur, looks like it cannot find the MapActivity class, im running it on the GoogleApps 1.5 instead of normal android 1.5 as well. http://pastebin.com/m3ee8dba2 Somebody plz help me - i am now dying.

• Connecting to a network drive programmatically and caching credentials

  - by Chris Doggett

  I'm finally set up to be able to work from home via VPN (using Shrew as a client), and I only have one annoyance. We use some batch files to upload config files to a network drive. Works fine from work, and from my team lead's laptop, but both of those machines are on the domain. My home system is not, and won't be, so when I run the batch file, I get a ton of "invalid drive" errors because I'm not a domain user. The solution I've found so far is to make a batch file with the following: explorer \\MACHINE1 explorer \\MACHINE2 explorer \\MACHINE3 Then manually login to each machine using my domain credentials as they pop up. Unfortunately, there are around 10 machines I may need to use, and it's a pain to keep entering the password if I missed one that a batch file requires. I'm looking into using the answer to this question to make a little C# app that'll take the login info once and login programmatically. Will the authentication be shared automatically with Explorer, or is there anything special I need to do? If it does work, how long are the credentials cached? Is there an app that does something like this automatically? Unfortunately, domain authentication via the VPN isn't an option, according to our admin. EDIT: If there's a way to pass login info to Explorer via the command line, that would be even easier using Ruby and highline.

• Ruby on Rails: How to sanitize a string for SQL when not using find and other built-in methods?

  - by williamjones

  I'm trying to sanitize a string that involves user input without having to resort to manually crafting my own possibly buggy regex if possible. There are a number of methods in Rails that can allow you to enter in native SQL commands, how do people escape user input for those? The question I'm asking is a broad one, but in my particular case, I'm working with a column in my Postgres database that Rails does not natively understand as far as I know, the tsvector, which holds plain text search information. Rails is able to write and read from it as if it's a string, however, unlike a string, it doesn't seem to be automatically escaping it when I do things like vector= inside the model. For example, when I do model.name='::', where name is a string, it works fine. When I do model.vector='::' it errors out: ActiveRecord::StatementInvalid: PGError: ERROR: syntax error in tsvector: "::" "vectors" = E'::' WHERE "id" = 1 This seems to be a problem caused by lack of escaping of the semicolons, and I can manually set the vector='\:\:' fine. I also had the bright idea, maybe I can just call something like: ActiveRecord::Base.connection.execute "UPDATE medias SET vectors = ? WHERE id = 1", "::" However, this syntax doesn't work, because the raw SQL commands don't have access to find's method of escaping and inputting strings by using the ? mark. This strikes me as the same problem as calling connection.execute with any type of user input, as it all boils down to sanitizing the strings, but I can't seem to find any way to manually call Rails' SQL string sanitization methods. Can anyone provide any advice?

• Why is iPdb not displaying STOUT after my input?

  - by BryanWheelock

  I can't figure out why ipdb is not displaying stout properly. I'm trying to debug why a test is failing and so I attempt to use ipdb debugger. For some reason my Input seems to be accepted, but the STOUT is not displayed until I (c)ontinue. Is this something broken in ipdb? It makes it very difficult to debug a program.

• Automatically release resources RAII-style in Perl

  - by Philip Potter

  Say I have a resource (e.g. a filehandle or network socket) which has to be freed: open my $fh, "<", "filename" or die "Couldn't open filename: $!"; process($fh); close $fh or die "Couldn't close filename: $!"; Suppose that process might die. Then the code block exits early, and $fh doesn't get closed. I could explicitly check for errors: open my $fh, "<", "filename" or die "Couldn't open filename: $!"; eval {process($fh)}; my $saved_error = $@; close $fh or die "Couldn't close filename: $!"; die $saved_error if $saved_error; but this kind of code is notoriously difficult to get right, and only gets more complicated when you add more resources. In C++ I would use RAII to create an object which owns the resource, and whose destructor would free it. That way, I don't have to remember to free the resource, and resource cleanup happens correctly as soon as the RAII object goes out of scope - even if an exception is thrown. Unfortunately in Perl a DESTROY method is unsuitable for this purpose as there are no guarantees for when it will be called. Is there a Perlish way to ensure resources are automatically freed like this even in the presence of exceptions? Or is explicit error checking the only option?

• Flash gets XML but the values are wrong, as3

  Flash receives the XML, but the values are wrong. How do I fix this? Problem I can see the XML loaded with no errors, but my output is way off. It's as though it's not receiving any values. Numbers in the output window and animation move rapidly. The Flash file runs as if it's variables where set to zero. I changed the order of my code, but that didn't help with this. Please explain how I can correct this.

• Python Socket Getting Connection Reset

  I created a threaded socket listener that stores newly accepted connections in a queue. The socket threads then read from the queue and respond. For some reason, when doing benchmarking with 'ab' (apache benchmark) using a concurrency of 2 or more, I always get a connection reset before it's able to complete the benchmark (this is taking place locally, so there's no external connection issue). class server: _ip = '' _port = 8888 def __init__(self, ip=None, port=None): if ip is not None: self._ip = ip if port is not None: self._port = port self.server_listener(self._ip, self._port) def now(self): return time.ctime(time.time()) def http_responder(self, conn, addr): httpobj = http_builder() httpobj.header('HTTP/1.1 200 OK') httpobj.header('Content-Type: text/html; charset=UTF-8') httpobj.header('Connection: close') httpobj.body("Everything looks good") data = httpobj.generate() sent = conn.sendall(data) def http_thread(self, id): self.log("THREAD %d: Starting Up..." % id) while True: conn, addr = self.q.get() ip, port = addr self.log("THREAD %d: responding to request: %s:%s - %s" % (id, ip, port, self.now())) self.http_responder(conn, addr) self.q.task_done() conn.close() def server_listener(self, host, port): self.q = Queue.Queue(0) sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.bind( (host, port) ) sock.listen(5) for i in xrange(4): #thread count thread.start_new(self.http_thread, (i+1, )) while True: self.q.put(sock.accept()) sock.close() server('', 9999) When running the benchmark, I get totally random numbers of good requests before it errors out, usually between 4 and 500. Edit: Took me a while to figure it out, but the problem was in sock.listen(5). Because I was using apache benchmark with a higher concurrency (5 and up) it was causing the backlog of connections to pile up, at which point the connections started getting dropped by the socket.

• How can I track down "Template process failed: undef error" in Perl's Template Toolkit?

  - by swisstony

  I've moved a Perl CGI app from one web host to another. Everything's running fine except for Template Tookit which is giving the following error: "Template process failed: undef error - This shouldn't happen at /usr/lib/perl5/5.8.8/CGI/Carp.pm line 314." The templates are working fine on the other web host. I've set the DEBUG_ALL flag when creating the template object, but it doesn't provide any additional info about errors just loads of debug output. I can't post the template source as there's lots of client specific stuff in it. I've written a simple test template and that works okay. Just wondering if anyone had seen this error before or has any ideas on the quickest way to find a fix for it. EDIT: Here's a snippet of the code that loads and processes the template. my $vars = {}; $vars->{page_url} = $page_url; $vars->{info} = $info; $vars->{is_valid} = 0; $vars->{invalid_input} = 0; $vars->{is_warnings} = 0; $vars->{is_invalid_price} = 0; $vars->{output_from_proc} = $proc_output; ... my $file = 'clientTemplate.html'; #create ref to hash use Template::Constants qw( :debug ); my $template = Template->new( { DEBUG => DEBUG_SERVICE | DEBUG_CONTEXT | DEBUG_PROVIDER | DEBUG_PLUGINS | DEBUG_FILTERS | DEBUG_PARSER | DEBUG_DIRS, EVAL_PERL => 1, INCLUDE_PATH => [ '/home/perlstuff/templates', ], } ); $template->process( $file, $vars ) || die "Template process failed: ", $template->error(), "\n";

• How to find specific/local files via CMake

  - by Andreas Romeyke

  Hello, I have a problem with a locally installed library. In my project there is the xmlrpc++0.7-library: myproject/ +-- xmlrpc++0.7/ +-- src/ I want that CMake fallbacks using the local xmlrpc++0.7 directory if not found otherwise. Two problems, the first one, find_path() or find_library() does not work with local dir. I used a workaround testing if variables processed by find_xxx() are empty or not. If empty I set them manually. The cmake generates the Makefile without errors now. But if I want to compile the project via make, the c++ compiler returns "error: XmlRpc.h: file not found". The file XmlRpc.h lies in myproject/xmlrpc++0.7/src and if I compile all them manually it works fine. Here is my CMakeLists.txt. I am very happy if anyone could me point to the right solution to use cmake under conditions described above. --- CMakeLists.txt --- project(webservice_tesseract) cmake_minimum_required(VERSION 2.6) set(CMAKE_INCLUDE_CURRENT_DIR ON) # find tesseract find_path(TESSERACT_INCLUDE_DIR tesseract/tesseractmain.h /opt/local/include /usr/local/include /usr/include ) find_library(TESSERACT_LIBRARY_DIR NAMES tesseract_main PATHS /opt/local/lib/ /usr/local/lib/ /usr/lib ) message(STATUS "looked for tesseract library.") message(STATUS "Include file detected: [${TESSERACT_INCLUDE_DIR}].") message(STATUS "Lib file detected: [${TESSERACT_LIBRARY_DIR}].") add_library(tesseract STATIC IMPORTED) set_property(TARGET tesseract PROPERTY IMPORTED_LOCATION ${TESSERACT_LIBRARY_DIR}/libtesseractmain.a ) #find xmlrpc++ message(STATUS "cmake home dir: [${CMAKE_HOME_DIRECTORY}].") set(LOCAL_XMLRPCPLUSPLUS ${CMAKE_HOME_DIRECTORY}/xmlrpc0.7++/) message(STATUS "xmlrpc++ local dir: [${LOCAL_XMLRPCPLUSPLUS}].") find_path(XMLRPCPLUSPLUS_INCLUDE_DIR XmlRpcServer.h ${LOCAL_XMLRPCPLUSPLUS}src /opt/local/include /usr/local/include /usr/include ) find_library(XMLRPCPLUSPLUS_LIBRARY_DIR NAMES XmlRpc PATHS ${LOCAL_XMLRPCPLUSPLUS} /opt/local/lib/ /usr/local/lib/ /usr/lib/ ) # next lines are an ugly workaround because cmake find_xxx() does not find local stuff if (XMLRPCPLUSPLUS_INCLUDE_DIR) else (XMLRPCPLUSPLUS_INCLUDE_DIR) set(XMLRPCPLUSPLUS_INCLUDE_DIR ${LOCAL_XMLRPCPLUSPLUS}src) endif (XMLRPCPLUSPLUS_INCLUDE_DIR) if (XMLRPCPLUSPLUS_LIBRARY_DIR) else (XMLRPCPLUSPLUS_LIBRARY_DIR) set(XMLRPCPLUSPLUS_LIBRARY_DIR ${LOCAL_XMLRPCPLUSPLUS}) endif (XMLRPCPLUSPLUS_LIBRARY_DIR) message(STATUS "looked for xmlrpc++ library.") message(STATUS "Include file detected: [${XMLRPCPLUSPLUS_INCLUDE_DIR}].") message(STATUS "Lib file detected: [${XMLRPCPLUSPLUS_LIBRARY_DIR}].") add_library(xmlrpc STATIC IMPORTED) set_property(TARGET xmlrpc PROPERTY IMPORTED_LOCATION ${XMLRPCPLUSPLUS_LIBRARY_DIR}/libXmlRpc.a ) #### link together include_directories(${XMLRPCPLUSPLUS_INCLUDE_DIR} ${TESSERACT_INCLUDE_DIR}) link_directories(${XMLRPCPLUSPLUS_LIBRARY_DIR} ${TESSERACT_LIBRARY_DIR}) add_library(simpleocr STATIC simple_ocr.cpp) add_executable(webservice_tesseract webservice.cpp) target_link_libraries(webservice_tesseract xmlrpc tesseract simpleocr)

• Declaring functors for comparison ??

  - by Mr.Gando

  Hello, I have seen other people questions but found none that applied to what I'm trying to achieve here. I'm trying to sort Entities via my EntityManager class using std::sort and a std::vector<Entity *> /*Entity.h*/ class Entity { public: float x,y; }; struct compareByX{ bool operator()(const GameEntity &a, const GameEntity &b) { return (a.x < b.x); } }; /*Class EntityManager that uses Entitiy*/ typedef std::vector<Entity *> ENTITY_VECTOR; //Entity reference vector class EntityManager: public Entity { private: ENTITY_VECTOR managedEntities; public: void sortEntitiesX(); }; void EntityManager::sortEntitiesX() { /*perform sorting of the entitiesList by their X value*/ compareByX comparer; std::sort(entityList.begin(), entityList.end(), comparer); } I'm getting a dozen of errors like : error: no match for call to '(compareByX) (GameEntity* const&, GameEntity* const&)' : note: candidates are: bool compareByX::operator()(const GameEntity&, const GameEntity&) I'm not sure but ENTITY_VECTOR is std::vector<Entity *> , and I don't know if that could be the problem when using the compareByX functor ? I'm pretty new to C++, so any kind of help is welcome.

• Getting error while connecting to facebook

  - by Bakhtiyor

  I have downloaded php-sdk for using facebook in php. I also created facebook application in the facebook web page in order to get API key and secret key. When I run example.php and try to connect to facebook it shows me the following error: Configuration errors: To fix this error, please set your Connect URL in the application settings editor. Once it has been set, users will be redirected to that URL instead of this page after logging in. I am using this php-sdk in the localhost. I tried to assign localhost as Connect URL but facebook doesn't accept it. I have read about Cross Domain Communication Channel and think this is what I need. But I don't know how to use it. Anyone can help me to solve this problem please? Update Actually what I need is following. I have Web Application and need to connect to facebook and search for users in facebook who has specific(user will specify this) Likes and Interests. Any idea about solving my problem?
