  • Execute sybase stored proc from hibernate

    - by Padmanabh
    I am having issues with executing a simple sybase stored proc from hibernate. The procedure takes some input and returns one record. I tried with the following tag in hibernate mappings file and java code. <hibernate-mapping> <sql-query name="sybaseproc" callable="true"> <return class="Myentity"> <return-property name="next" column="next"/> </return> { ? = call nextnum(?,?) } </sql-query> </hibernate-mapping> java code is as follows Query q = session.getNamedQuery("sybaseproc"); q.setString(0,"test"); q.setInteger(1,new Integer(10)); Myentity entity = (Myentity) q.uniqueResult(); When I run my test. I get a error saying "Errors in Named Query sybaseproc" and the test does not run. Any help is appreciated. Thanks Padmanabh

  • 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)

  • undefined references

    - by Brandon
    Hello, I'm trying to compile some fortran code and I'm running into some confusing linking errors. I have some code that I compile and place into a static library: >gfortran -c -I../../inc -o bdout.o bdout.F >ar rv libgeo.a bdout.o I then try to compile against that library with some simple test code and get the following: >gfortran -o mytest -L -lgeo mytest.F /tmp/cc4uvcsj.o: In function `MAIN__': mytest.F:(.text+0xb0): undefined reference to `ncwrite1_' collect2: ld returned 1 exit status It's not in the object naming because everything looks fine: >nm -u libgeo.a bdout.o: U _gfortran_exit_i4 U _gfortran_st_write U _gfortran_st_write_done U _gfortran_transfer_character U _gfortran_transfer_integer U ncobjcl_ U ncobjwrp_ U ncopencr_ U ncopenshcr_ U ncopenwr_ U ncwrite1_ U ncwrite2_ U ncwrite3_ U ncwrite4_ U ncwritev_ I can check the original object file too: >nm -u bdout.o U _gfortran_exit_i4 U _gfortran_st_write U _gfortran_st_write_done U _gfortran_transfer_character U _gfortran_transfer_integer U ncobjcl_ U ncobjwrp_ U ncopencr_ U ncopenshcr_ U ncopenwr_ U ncwrite1_ U ncwrite2_ U ncwrite3_ U ncwrite4_ U ncwritev_ The test code simply contains a single call to a function defined in bdout.o: program hello print *,"Hello World!" call ncwrite1( istat, f, ix2, ix3, ix4, ix5, ih ) end program hello I can't figure out what the problem is. Does anyone have any suggestions? Maybe even just a way to track the problem down? Cheers.

  • Boost::Mutex & Malloc

    - by M. Tibbits
    Hi all, I'm trying to use a faster memory allocator in C++. I can't use Hoard due to licensing / cost. I was using NEDMalloc in a single threaded setting and got excellent performance, but I'm wondering if I should switch to something else -- as I understand things, NEDMalloc is just a replacement for C-based malloc() & free(), not the C++-based new & delete operators (which I use extensively). The problem is that I now need to be thread-safe, so I'm trying to malloc an object which is reference counted (to prevent excess copying), but which also contains a mutex pointer. That way, if you're about to delete the last copy, you first need to lock the pointer, then free the object, and lastly unlock & free the mutex. However, using malloc to create a boost::mutex appears impossible because I can't initialize the private object as calling the constructor directly ist verboten. So I'm left with this odd situation, where I'm using new to allocate the lock and nedmalloc to allocate everything else. But when I allocate a large amount of memory, I run into allocation errors (which disappear when I switch to malloc instead of nedmalloc ~ but the performance is terrible). My guess is that this is due to fragmentation in the memory and an inability of nedmalloc and new to place nice side by side. There has to be a better solution. What would you suggest?

  • Problem with ActionScript 3.0 button to URL and root movieclip

    - by aarontb
    Okay, so, here's what the problem is. I'm creating a flash site with each page being it's own movieclip and Scene 1 being the menu and other things that stay on the site. I've created a MovieClip called 'HowWorksScene'. The movieclip has 2 buttons that link out to different URLs, however, I'm sure that when 1 of the button scripts work, the same script will work for the other...so here's the problem that I'm having with the Button stop(); VidDemo_btn.addEventListener(MouseEvent.CLICK, video); function video(event:MouseEvent):void { var link:URLRequest = new URLRequest('www.youtube.com'); navigateToURL(link); } Problem is that I cannot GET to that frame to even determine an error. The problem preventing me from getting to this point is a call function. In the "HomePage" movieclip, when the button is pressed to go to the next scene, "Homepage" fades out and flys left then the next frame is 1 frame but activates the next movieclipe "HowWorksScene"...but without errors, it simply goes to frame 17 of "Homepage". I've tried doing _root.gotoAndPlay(17); but get an undefined error. So, I guess my question is: What is the BEST way to direct from within a movieclip to a frame in the parent Scene? I've even tried using gotoAndPlay(17, "Scene 1"); And that still did not work. Please let me know ASAP!

  • Am I Writing Assembly Or NASM?

    - by cam
    I'm fed up with this. I've been trying to just get a grip on assembly for awhile, but I feel like I'm coding towards my compiler rather than a language. I've been using this tutorial, and so far it's giving me hell. I'm using NASM, which may be the problem, but I figured it was the most popular one. I'm simply trying to learn the most general form of assembly, so I decided to learn x86. I keep running into stupid errors, like not being able to increment a variable. Here's the latest one: not being able to use div. mov bx, 0; mov cx, 0; jmp start; start: inc cx; mov ax, cx; div 3; <-- invalid combination of opcode and operand cmp ah,0; jz totalvalue; mov ax, cx; div 5; <-- invalid combination of opcode and operand cmp ah, 0; jz totalvalue; cmp cx, 1000; jz end; totalvalue: add bx,cx; jmp start; jmp end; end: mov ah,4ch; mov al,00; int 21h; Should I change compilers? It seems like division should be standard. Do I need to read two tutorials (one on NASM, and one on x86?). Any specific help on this problem?

  • Can't start the portable version of NetBeans 6.9.1 IDE

    I downloaded the portable version of netbeans netbeans-6.9.1-201007282301-ml.zip from the netbeans site and changed the config file in etc/netbeans.conf as indicated on the netbeans site. The file contents are below. # ${HOME} will be replaced by JVM user.home system property #netbeans_default_userdir="${HOME}/.netbeans/6.9" netbeans_default_userdir=".netbeans/6.9" # Options used by NetBeans launcher by default, can be overridden by explicit # command line switches: netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-XX:MaxPermSize=200m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true" # Note that a default -Xmx is selected for you automatically. # You can find this value in var/log/messages.log file in your userdir. # The automatically selected value can be overridden by specifying -J-Xmx here # or on the command line. # If you specify the heap size (-Xmx) explicitely, you may also want to enable # Concurrent Mark & Sweep garbage collector. In such case add the following # options to the netbeans_default_options: # -J-XX:+UseConcMarkSweepGC -J-XX:+CMSClassUnloadingEnabled -J-XX:+CMSPermGenSweepingEnabled # (see http://wiki.netbeans.org/wiki/view/FaqGCPauses) # Default location of JDK, can be overridden by using --jdkhome <dir>: #netbeans_jdkhome="/path/to/jdk" netbeans_jdkhome="C:\Program Files\Java\jdk1.6.0_24\" # Additional module clusters, using ${path.separator} (';' on Windows or ':' on Unix): #netbeans_extraclusters="/absolute/path/to/cluster1:/absolute/path/to/cluster2" # If you have some problems with detect of proxy settings, you may want to enable # detect the proxy settings provided by JDK5 or higher. # In such case add -J-Djava.net.useSystemProxies=true to the netbeans_default_options. But it refuses to start when i try to run it. If i change the JDK path to something incorrect it complains that it can't find the jdk so i think the jdk path is correct. It also creates a .netbeans directory when i try to start it. I don't see any errors and it just doesn't do anything else observable. Does anybody know how to set up this version of netbeans? Thanks.

  • Generate a set of strings with maximum edit distance

    - by Kevin Jacobs
    Problem 1: I'd like to generate a set of n strings of fixed length m from alphabet s such that the minimum Levenshtein distance (edit distance) between any two strings is greater than some constant c. Obviously, I can use randomization methods (e.g., a genetic algorithm), but was hoping that this may be a well-studied problem in computer science or mathematics with some informative literature and an efficient algorithm or three. Problem 2: Same as above except that adjacent characters cannot repeat; the i'th character in each string may not be equal to the i+1'th character. E.g., 'CAT', 'AGA' and 'TAG' are allowed, 'GAA', 'AAT', and 'AAA' are not. Background: The basis for this problem is bioinformatic and involves designing unique DNA tags that can be attached to biologically derived DNA fragments and then sequenced using a fancy second generation sequencer. The goal is to be able to recognize each tag, allowing for random insertion, deletion, and substitution errors. The specific DNA sequencing technology has a relatively low error rate per base (~1%), but is less precise when a single base is repeated 2 or more times (motivating the additional constraints imposed in problem 2).

  • Is my heuristic algorithm correct? (Sudoku solver)

    - by Aposperite
    First of -yes this IS a homework- but it's primarily a theoretical question rather than a practical one, I am simply asking a confirmation if I am thinking correctly or any hints if I am not. I have been asked to compile a simple Sudoku solver (on Prolog but that is not so important right now) with the only limitation being that it must utilize a heuristic function using Best-First Algorithm. The only heuristic function I have been able to come up with is explained below: 1. Select an empty cell. 1a. If there are no empty cells and there is a solution return solution. Else return No. 2. Find all possible values it can hold. %% It can't take values currently assigned to cells on the same line/column/box. 3. Set to all those values a heuristic number starting from 1. 4. Pick the value whose heuristic number is the lowest && you haven't checked yet. 4a. If there are no more values return no. 5. If a solution is not found: GoTo 1. Else Return Solution. // I am sorry for errors in this "pseudo code." If you want any clarification let me know. So am I doing this right or is there any other way around and mine is false? Thanks in advance.

  • MVC Localization of Default Model Binder

    - by Dai Bok
    Hi, I am currently trying to figure out how to localize the error messages generated by MVC. Let me use the default model binder as an example, so I can explain the problem. Assuming I have a form, where a user enters thier age. The user then enters "ten" in to the form, but instead of getting the expected error of "Age must be beween 18 and 25." the message "The value 'ten' is not valid for Age." is displayed. The entity's age property is defined below: [Range(18, 25, ErrorMessageResourceType = typeof (Errors), ErrorMessageResourceName = "Age", ErrorMessage = "Range_ErrorMessage")] public int Age { get; set; } After some digging, I notice that this error text comes from the System.Web.Mvc.Resources.DefaultModelBinder_ValueInvalid in the MvcResources.resx file. Now, how can create localized versions of this file? As A solution, for example, should I download MVC source and add MvcResources.en_GB.resx, MvcResources.fr_FR.resx, MvcResources.es_ES.resx and MvcResources.de_DE.resx, and then compile my own version of MVC.dll? But I don't like this idea. Any one else know a better way?

  • WPF validation red border doesn't show If UserControl collapsed first

    - by Creepy Gnome
    There seems to be a bug with WPF in 3.5, and I was hoping someone may have found a workaround. Basically if you have a custom UserControl that contains a TextBox and it is in a Window but initialized to be Collapsed by default in the xaml or code behind if it fails validation when you make the control visible it will not show the red border until it fails while visible. However, this works correctly when visibility is set to Hidden, just no when Collapsed. I am already overriding the ErrorTemplate with a style to workaround the Adornment issue with the red border staying visibile when you collapse the control. Below is my full style for the TextBox. If there is any additional changes or additions to make it work correctly with collapsed controls that would be great. <Style TargetType="TextBox"> <Setter Property="Margin" Value="3" /> <Setter Property="Validation.ErrorTemplate"> <Setter.Value> <ControlTemplate> <ControlTemplate.Resources> <BooleanToVisibilityConverter x:Key="converter" /> </ControlTemplate.Resources> <DockPanel LastChildFill="True"> <Border BorderThickness="2" BorderBrush="Red" Visibility="{ Binding ElementName=placeholder, Mode=OneWay, Path=AdornedElement.IsVisible, Converter={StaticResource converter}}" > <AdornedElementPlaceholder x:Name="placeholder" /> </Border> </DockPanel> </ControlTemplate> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true" > <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}" /> </Trigger> </Style.Triggers> </Style>

  • question/problem regarding assigning an array of char *

    - by Fantastic Fourier
    Hi I'm working with C and I have a question about assigning pointers. struct foo { int _bar; char * _car[MAXINT]; // this is meant to be an array of char * so that it can hold pointers to names of cars } int foofunc (void * arg) { int bar; char * car[MAXINT]; struct foo thing = (struct foo *) arg; bar = arg->_bar; // this works fine car = arg->_car; // this gives compiler errors of incompatible types in assignment } car and _car have same declaration so why am I getting an error about incompatible types? My guess is that it has something to do with them being pointers (because they are pointers to arrays of char *, right?) but I don't see why that is a problem. when i declared char * car; instead of char * car[MAXINT]; it compiles fine. but I don't see how that would be useful to me later when I need to access certain info using index, it would be very annoying to access that info later. in fact, I'm not even sure if I am going about the right way, maybe there is a better way to store a bunch of strings instead of using array of char *?

  • Debug NAudio MP3 reading difference?

    - by Conrad Albrecht
    My code using NAudio to read one particular MP3 gets different results than several other commercial apps. Specifically: My NAudio-based code finds ~1.4 sec of silence at the beginning of this MP3 before "audible audio" (a drum pickup) starts, whereas other apps (Windows Media Player, RealPlayer, WavePad) show ~2.5 sec of silence before that same drum pickup. The particular MP3 is "Like A Rolling Stone" downloaded from Amazon.com. Tested several other MP3s and none show any similar difference between my code and other apps. Most MP3s don't start with such a long silence so I suspect that's the source of the difference. Debugging problems: I can't actually find a way to even prove that the other apps are right and NAudio/me is wrong, i.e. to compare block-by-block my code's results to a "known good reference implementation"; therefore I can't even precisely define the "error" I need to debug. Since my code reads thousands of samples during those 1.4 sec with no obvious errors, I can't think how to narrow down where/when in the input stream to look for a bug. The heart of the NAudio code is a P/Invoke call to acmStreamConvert(), which is a Windows "black box" call which I can't think how to error-check. Can anyone think of any tricks/techniques to debug this?

  • Passing row from UIPickerView to integer CoreData attribute

    - by Gordon Fontenot
    I'm missing something here, and feeling like an idiot about it. I'm using a UIPickerView in my app, and I need to assign the row number to a 32-bit integer attribute for a Core Data object. To do this, I am using this method: -(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { object.integerValue = row; } This is giving me a warning: warning: passing argument 1 of 'setIntegerValue:' makes pointer from integer without a cast What am I mixing up here? --EDIT 1-- Ok, so I can get rid of the errors by changing the method to do the following: NSNumber *number = [NSNumber numberWithInteger:row]; object.integerValue = rating; However, I still get a value of 0 for object.integerValue if I use NSLog to print it out. object.integerValue has a max value of 5, so I print out number instead, and then I'm getting a number above 62,000,000. Which doesn't seem right to me, since there are 5 rows. If I NSLog the row variable, I get a number between 0 and 5. So why do I end up with a completely different number after casting the number to NSNumber?

  • Strcpy and malloc issues

    - by mrblippy
    Hi, i am having trouble getting a method relating to a linked list working, i get the errors: assignment makes pointer from integer without a cast and passing argument 1 of âstrcpyâ makes pointer from integer without a cast. i have tried to include all the relevant code, but let me know if you need more info. thanks. struct unit { char code[5]; char *name; node_ptr students; }; typedef struct node *node_ptr; struct node { int student_id; char *studentname; node_ptr next; }; void enrol_student(struct unit u[], int n) { int i, p; int student_id = 0; char code_to_enrol[7]; char buffer[100]; node_ptr studentslist; scanf("%s\n", code_to_enrol); for(i=0; i <= n; i++) { studentslist = u[i].students; if(strcmp(u[i].code ,code_to_enrol)<=0) { scanf("enter student details %d %s\n", &studentID, buffer); p = (char *) malloc (strlen(buffer)+1); strcpy(p, buffer); insert_in_order(student_id, buffer, studentslist); } } } void insert_in_order(int n, char *i, node_ptr list) { node_ptr before = list; node_ptr students = (node_ptr) malloc(sizeof(struct node)); students->ID = n; students->name = *i; while(before->next && (before->next->ID < n)) { before = before->next; } students->next = before->next; before->next = students; }

  • Origin null is not allowed by Access-Control-Allow-Origin

    - by JIGGABITS
    I'm currently working with the SoundCloud API and would like to have a track embed when a button is clicked. I get two errors: XMLHttpRequest cannot load http://soundcloud.com/oembed.json?url=http%3A%2F%2Fapi.soundcloud.com%2Ftracks%2F48419073. Origin null is not allowed by Access-Control-Allow-Origin. AND Uncaught TypeError: Cannot read property 'html' of null Here is my code: <button onclick="getPopular()">+1</button> <div id="track"></div> <script src="http://connect.soundcloud.com/sdk.js" type="text/JavaScript"></script> <script type="text/JavaScript"> SC.initialize({ client_id: "**************", }); var getPopular = function() { SC.get("/tracks", {limit: 1}, function(tracks) { var track = tracks[0]; alert("Latest track: " + track.title); SC.oEmbed(track.uri, document.getElementById("track")); }); }; </script> I use an alert in my code to let me know that it is actually taking information from the SoundCloud API. I'm just not sure what else is preventing it from embedding. Thanks, ahead of time, or looking at my question. jiggabits

  • Error in creating trigger using PHP script.. Please help!!!! Geeks

    - by Parth
    I've been successful in creating a simple trigger with a PHP script. The problem comes when I have to use "DELIMITER" in my trigger creating because I have nested if/then statements. For example, the following DOES work: $sql = 'CREATE TRIGGER `database`.`detail` BEFORE INSERT on `database`.`vibez_detail` FOR EACH ROW set @a=new.realtime_value'; $junk = mysqli_query($link, $sql); However, if I need to use "DELIMITER" I get errors galore. Here's what works if I go to the MySQL client at the server: DELIMITER $$; DROP TRIGGER `database`.`detail`$$ CREATE TRIGGER `database`.`detail` BEFORE INSERT on `database`.`vibez_detail` FOR EACH ROW BEGIN set new.data_rate = 69; insert into alarm_trips_parent values (null, new.data_rate, 6969, now()); set @tripped_time = now(); set @tripped:=true; end if; end if; END$$ DELIMITER ;$$ How can I construct the PHP code to get this to work? Seems the mysqli_query($link, $sql) chokes as soon as I put "DELIMITER" in the $sql variable. I get the following error when I attempt to do so: Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DELIMITER //; CREATE TRIGGER `database`.`detail` BEFORE INS' at line 1 Even The concept for using mysqli_multi_query(); didn't worked for me.... :(

  • Scheduling of tasks to a single resource using Prolog

    - by Reed Debaets
    I searched through here as best I could and though I found some relevant questions, I don't think they covered the question at hand: Assume a single resource and a known list of requests to schedule a task. Each request includes a start_after, start_by, expected_duration, and action. The goal is to schedule the tasks for execution as soon as possible while keeping each task scheduled between start_after and start_by. I coded up a simple prolog example that I "thought" should work but I've been unfortunately getting errors during run time: "=/2: Arguments are not sufficiently instantiated". Any help or advice would be greatly appreciated startAfter(1,0). startAfter(2,0). startAfter(3,0). startBy(1,100). startBy(2,500). startBy(3,300). duration(1,199). duration(2,199). duration(3,199). action(1,'noop1'). action(2,'noop2'). action(3,'noop3'). can_run(R,T) :- startAfter(R,TA),startBy(R,TB),T>=TA,T=<TB. conflicts(T,R1,T1) :- duration(R1,D1),T=<D1+T1,T>T1. schedule(R1,T1,R2,T2,R3,T3) :- can_run(R1,T1),\+conflicts(T1,R2,T2),\+conflicts(T1,R3,T3), can_run(R2,T2),\+conflicts(T2,R1,T1),\+conflicts(T2,R3,T3), can_run(R3,T3),\+conflicts(T3,R1,T1),\+conflicts(T3,R2,T2). % when traced I *should* see T1=0, T2=400, T3=200 Edit: conflicts goal wasn't quite right: needed extra TT1 clause. Edit: Apparently my schedule goal works if I supply valid Request,Time pairs ... but I'm stucking trying to force prolog to find valid values for T1..3 when given R1..3?

  • Problems with reading into buffer using boost::asio::async_read

    - by Max
    Good day. I have a Types.hpp file in my project. And within it i have: .... namespace RC { ..... ..... struct ViewSettings { .... }; ..... } In the Server.cpp file I'm including this Types.hpp file, and i have there: class Session { ..... RC::ViewSettings tmp; boost::asio::async_read(socket_, boost::asio::buffer(&tmp, sizeof(RC::ViewSettings)), boost::bind(&Session::Finish_Reading_Data, shared_from_this(), boost::asio::placeholders::error)); ..... } And during the compilation i have an errors: error C2825: 'F': must be a class or namespace when followed by '::' : see reference to class template instantiation 'boost::_bi::result_traits<R,F>' being compiled with [ R=boost::_bi::unspecified, F=void (__thiscall Session::* )(void) ] : see reference to class template instantiation 'boost::_bi::bind_t<R,F,L>' being compiled with [ R=boost::_bi::unspecified, F=void (__thiscall Session::* )(void), L=boost::_bi::list2<boost::_bi::value<boost::shared_ptr<Session>>,boost::arg<1>> ] error C2039: 'result_type' : is not a member of '`global namespace'' And the code like this works in proper way: int w; boost::asio::async_read(socket_, boost::asio::buffer(&w, sizeof(int)), boost::bind(&Session::Handle_Read_Width, shared_from_this(), boost::asio::placeholders::error)); Please, help. What's the problem here? Thanks in advance.

  • Getting a variable into another class through properties or button tags with Iphone SDK?

    - by MarcZero
    Hello. I have been pounding my head against a wall trying to figure out what I think is a simple thing to do, but I have, so far, been unable to figure it out with the iPhone SDK. I have a view with 4 buttons. When I push the buttons, I have another view called and come up to take over the screen. I want to have a simple variable passed from the old view to the new view. The purpose of this is to know what button was pressed out of the four identical ones. (trying to get an int value of 1 through 4) Here is what I have tried so far: I initially tried to call the variable from the class itself. My understanding was that my new view was only sitting on top of the old view, so it should not have been released. I could not get access to the variable as the variable was said to not be declared. I then tried to create a method that would return the int value. Again, the view class was not seen and was being declared as a "first use" of it. I then attempted to follow another similar post on here that suggested to try and send the button tag number to some part of the new view. I attempted to do this by setting the new views button title but I still cannot figure out a way to code it without coming up with errors. I am just looking for what method would be the best for me to pursue. I have no problem going back and reading the books on Objective-C, but I'm just trying to figure out which way I should concentrate on. Thank you for any insight.
