  • Steps in creating a web service using Axis2 - The client code

    - by zengr
    I am trying to create a web service, my tools of trade are: ** Axis2, Eclipse, Tomcat, Ant ** I need to create a web service from Code, i.e. Write a basic java class which will have the methods to be declared in the WSDL. Then use java2WSDL.sh to create my WSDL. So, is this approach correct: Write my Java class with actual business logic package packageNamel; public class Hello{ public void World(String name) { SOP("Hello" + name); } } Now, when I pass this Hello.java to java2WSDL.sh, this will give me the WSDL. Finally, I will write the services.xml file, and create the Hello.aar with following dir structure: Hello.aar packageName Hello.class META-INF services.xml MANIFEST.MF Hello.WSDL Now, I assume, my service will be deployed when I put the aar in tomcat1/webapps/axis2/WEB-INF/services But, here comes my problem, HOW DO I ACCESS THE METHOD World(String name)???!!, i.e. I am clueless about the client code! Please enlighten me on making a very basic web service and calling the method. The above described 3 steps might be wrong. It's a community wiki, feel free to edit. Thanks

  • WPF/SL EventAggregator implementation with durable subscribers behavior?

    - by sha1dy
    Hi. Currently I'm building an application using latest Prism for Silverlight 4. I've a module and in that module I've two views with view models. Also I've a module view with two regions for each view. In module initialization I'm registering my views and view models in Unity container and also register views with corresponding regions. The problem is that views should display something similar to table-detail information - first view shows available entities ans the second view shows detail of selected entity. I need a way how to pass them initial selected entity. Newly created first view doesn't have any selected entity and newly created second view doesn't show any details. Currently I'm doing that this way: In module I create two view models and register them as instances in Unity container and then I register views as types for corresponding regions. Each view subscribes to EntitySelectedEvent from EventAggregator. Module initializer publish this event after initialization and this way two views are selecting the same entity. I know this looks ugly - I tried publishing this event from one of view models but the problems is that EventAggregator in Prism doesn't support durable subscribers - this means that if the second view model didn't subscribe to event before the first view model fired it, it won't receive and event. I know this is a normal behavior of EventAggregator, but I'm looking for a solution when view models can fire events without depending on initialization order of them - that is the first model can fire event before the second model was created and the second model will receive this 'queued' event after subscribing to it. Are there any other messaging implementations for WPF/SL which do support such behavior or using a mediator (in my example it's a module itself) isn't such a bad idea after all? One big problem with mediator is that models must be created right away in initialize and they can't be registered as types in container because this leads again to missing subscribers.

  • Sybase: how can I remove non-printable characters from CHAR or VARCHAR fields with SQL?

    - by Kenny Drobnack
    I'm working with a Sybase database that seems to have non-printable characters in some of the string fields and this is throwing off some of our processing code. At first glance, it seemed to only be newlines and carriage returns, but we also have an ASCII code 27 in there - an ESC character, some accented characters, and some other oddities in there. I have no direct access to change the database, so changing the bad data isn't an option, yet. For now I have to make do with just filtering it out. We're trying to export the table data from one database and load it into a database used by another application in a nightly batch process. Ideally, I'd like to have a function that I can pass a list of characters and just have Sybase return the data with those characters removed. I'd like to keep it something we could do in plain SQL if possible. Something like this to remove characters that are ASCII 0 - 31. select str_replace(FIELD1, (0-31), NULL) as FIELD1, str_replace(FIELD2, (0-31), NULL) as FIELD2 from TABLE So far, str_replace is the nearest I can find, but it only allows replacing one string with another. No support for character ranges and won't let me do the above. We're running on Sybase ASE 12.5 on Unix servers.

  • Reordering arguments using recursion (pro, cons, alternatives)

    - by polygenelubricants
    I find that I often make a recursive call just to reorder arguments. For example, here's my solution for endOther from codingbat.com: Given two strings, return true if either of the strings appears at the very end of the other string, ignoring upper/lower case differences (in other words, the computation should not be "case sensitive"). Note: str.toLowerCase() returns the lowercase version of a string. public boolean endOther(String a, String b) { return a.length() < b.length() ? endOther(b, a) : a.toLowerCase().endsWith(b.toLowerCase()); } I'm very comfortable with recursions, but I can certainly understand why some perhaps would object to it. There are two obvious alternatives to this recursion technique: Swap a and b traditionally public boolean endOther(String a, String b) { if (a.length() < b.length()) { String t = a; a = b; b = t; } return a.toLowerCase().endsWith(b.toLowerCase()); } Not convenient in a language like Java that doesn't pass by reference Lots of code just to do a simple operation An extra if statement breaks the "flow" Repeat code public boolean endOther(String a, String b) { return (a.length() < b.length()) ? b.toLowerCase().endsWith(a.toLowerCase()) : a.toLowerCase().endsWith(b.toLowerCase()); } Explicit symmetry may be a nice thing (or not?) Bad idea unless the repeated code is very simple ...though in this case you can get rid of the ternary and just || the two expressions So my questions are: Is there a name for these 3 techniques? (Are there more?) Is there a name for what they achieve? (e.g. "parameter normalization", perhaps?) Are there official recommendations on which technique to use (when)? What are other pros/cons that I may have missed?

  • Generic allocator class without variadic templates?

    - by rainer
    I am trying to write a generic allocator class that does not really release an object's memory when it is free()'d but holds it in a queue and returns a previously allocated object if a new one is requested. Now, what I can't wrap my head around is how to pass arguments to the object's constructor when using my allocator (at least without resorting to variadic templates, that is). The alloc() function i came up with looks like this: template <typename... T> inline T *alloc(const &T... args) { T *p; if (_free.empty()) { p = new T(args...); } else { p = _free.front(); _free.pop(); // to call the ctor of T, we need to first call its DTor p->~T(); p = new( p ) T(args...); } return p; } Still, I need the code to be compatible with today's C++ (and older versions of GCC that do not support variadic templates). Is there any other way to go about passing an arbitrary amount of arguments to the objects constructor?

  • Convert string to decimal retaining the exact input format

    - by Brett
    Hi All, I'm sure this is a piece of cake but I'm really struggling with something that seems trivial. I need to check the inputted text of a textbox on the form submit and check to see if it's within a desired range (I've tried a Range Validator but it doesn't work for some reason so I'm trying to do this server-side). What I want to do is: Get the value inputted (eg. 0.02), replace the commas and periods, convert that to a decimal (or double or equivalent) and check to see if it's between 0.10 and 35000.00. Here's what I have so far: string s = txtTransactionValue.Text.Replace(",", string.Empty).Replace(".", string.Empty); decimal transactionValue = Decimal.Parse(s); if (transactionValue >= 0.10M && transactionValue <= 35000.00M) // do something If I pass 0.02 into the above, transactionValue is 2. I want to retain the value as 0.02 (ie. do no format changes to it - 100.00 is 100.00, 999.99 is 999.99) Any ideas? Thanks in advance, Brett

  • c - strncpy issue

    - by Joe
    Hi there, I am getting segmentation fault when using strncpy and (pointer-to-struct)-(member) notation: I have simplified my code. I initialise a struct and set all of it's tokens to an empty string. Then a declare a pointer to a struct and assign the address of the struct to it. I pass the pointer to a function. I can print out the contents of the struct at the beginning of the function, but if I try to use the tp - mnemonic in a strncpy function, I get seg fault. Can anyone tell me what I am doing wrong? typedef struct tok { char* label; char* mnem; char* operand; }Tokens; Tokens* tokenise(Tokens* tp, char* line) { // This prints fine printf("Print this - %s\n", tp -> mnem); // This function gives me segmentation fault strncpy(tp -> mnem, line, 4); return tp; } int main() { char* line = "This is a line"; Tokens tokens; tokens.label = ""; tokens.mnem = "load"; tokens.operand = ""; Tokens* tp = &tokens; tp = tokenise(tp, line); return 0; } I have used printf statements to confirm that the code definitely stops executing at the strncpy function. Can anyone tell me where I am going wrong? Many thanks Joe

  • WPF: How do I get a reference to a styled window control in code behind?

    - by Brad
    I have a window defined with a style: <Window x:Class="winBorderless" x:Name="winBorderless" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Local="clr-namespace:WindowStyle" Style="{StaticResource Window_Cartesia}" WindowStartupLocation="CenterScreen" BorderThickness="1" BorderBrush="#FF9CAAC1" Margin="5" Title="[Document Title]"> and the style defined in an application level dictionary: <Style x:Key="Window_Cartesia" TargetType="{x:Type Window}"> <Setter Property="WindowStyle" Value="None"/> <Setter Property="AllowsTransparency" Value="True"/> <Setter Property="Background" Value="Transparent"/> <EventSetter Event="Loaded" Handler="Loaded"/> <EventSetter Event="PreviewKeyDown" Handler="Preview_KeyDown"/> <EventSetter Event="MouseMove" Handler="FullScreen_MouseMove"/> <Setter Property="Template"> In code behind I have a reference to the Window instance set: Win = DirectCast(sender, winBorderless) This allows access to the window properties as the EventSetters pass references to the various controls. However, it doesn't provide for access to the controls defined in the style through the window reference as they don't exist there. So, what is the best way to reference a control through code behind that is defined in the style. I'd prefer not to iterate the trees to find them but ya gotta do....

  • Place Query Results into Array then Implode?

    - by jason
    Basically I pull an Id from table1, use that id to find a site id in table2, then need to use the site ids in an array, implode, and query table3 for site names. I cannot implode the array correctly first I got an error, then used a while loop. With the while loop the output simply says: Array $mysqli = mysqli_connect("server", "login", "pass", "db"); $sql = "SELECT MarketID FROM marketdates WHERE Date = '2010-04-04 00:00:00' AND VenueID = '2'"; $result = mysqli_query($mysqli, $sql) or die(mysqli_error($mysqli)); $dates_id = mysqli_fetch_assoc ( $result ); $comma_separated = implode(",", $dates_id); echo $comma_separated; //This Returns 79, which is correct. $sql = "SELECT SIteID FROM bookings WHERE BSH_ID = '1' AND MarketID = '$comma_separated'"; $result = mysqli_query($mysqli, $sql) or die(mysqli_error($mysqli)); // This is where my problems start $SIteID = array(); while ($newArray = mysqli_fetch_array($result, MYSQLI_ASSOC)) { $SIteID[] = $newArray[SIteID]; } $locationList = implode(",",$SIteID); ?> Basically what I need to do is correctly move the query results to an array that I can implode and use in a 3rd query to pull names from table3.

  • jQuery .animate() not animating backgroundPosition in IE

    - by mikemike
    I'm trying to animate a background image to move down a set amount of pixels but remain in the center of the page. Upon another click of an element I need it to move back to the top, but still remain in the center. Below is the current code: $(document).ready(function() { $('#email_campaigns').click(function(){ var width = $(window).width(); width = (width / 2) - 700; if($('#email_campaigns_box').css('display') == 'none'){ //$('body').css('background-position','center 119px'); $('body').animate({ backgroundPosition: (width + "px 119px") }, {duration:500}); } else { //$('body').css('background-position','center top'); $('body').animate({ backgroundPosition: (width + "px 0px") }, {duration:500}); } $('#email_campaigns_box').slideToggle("slow"); $('#client_login_box').slideUp("slow"); }); $('#client_login').click(function(){ var width = $(window).width(); width = (width / 2) - 700; alert(width); if($('#client_login_box').css('display') == 'none'){ //$('body').css('background-position','center 119px'); $('body').animate({ backgroundPosition: (width + "px 119px") }, {duration:500}); } else { //$('body').css('background-position','center top'); $('body').animate({ backgroundPosition: (width + "px 0px") }, {duration:500}); } $('#client_login_box').slideToggle("slow"); $('#email_campaigns_box').slideUp("slow"); }); }); I cannot pass 'center', as it will onyl accept numeric values. My goal is to calulate the center of the page in pixels (width = (width / 2) - 700;), and then animate to this rough position (it's normally out by a few pixels due to scrollbars, and then force to the center using a .css() call. The problem is that IE does not want to play ball. IE will not animate at all. Firefox/Safari/Chrome all work as expected. Below is a live example: http://recklessnewmedia.com/new/# (click 'email campaigns' at the top). Thanks

  • Passing VB Callback function to C dll - noob is stuck.

    - by WaveyDavey
    Callbacks in VB (from C dll). I need to pass a vb function as a callback to a c function in a dll. I know I need to use addressof for the function but I'm getting more and more confused as to how to do it. Details: The function in the dll that I'm passing the address of a callback to is defined in C as : PaError Pa_OpenStream( PaStream** stream, const PaStreamParameters *inputParameters, const PaStreamParameters *outputParameters, double sampleRate, unsigned long framesPerBuffer, PaStreamFlags streamFlags, PaStreamCallback *streamCallback, void *userData ); where the function is parameter 7, *streamCallback. The type PaStreamCallback is defines thusly: typedef int PaStreamCallback( const void *input, void *output, unsigned long frameCount, const PaStreamCallbackTimeInfo* timeInfo, PaStreamCallbackFlags statusFlags, void *userData ); In my vb project I have: Private Declare Function Pa_OpenStream Lib "portaudio_x86.dll" _ ( ByVal stream As IntPtr _ , ByVal inputParameters As IntPtr _ , ByVal outputParameters As PaStreamParameters _ , ByVal samprate As Double _ , ByVal fpb As Double _ , ByVal paClipoff As Long _ , ByVal patestCallBack As IntPtr _ , ByVal data As IntPtr) As Integer (don't worry if I've mistyped some of the other parameters, I'll get to them later! Let's concentrate on the callback for now.) In module1.vb I have defined the callback function: Function MyCallback( ByVal inp As Byte, _ ByVal outp As Byte, _ ByVal framecount As Long, _ ByVal pastreamcallbacktimeinfo As Byte, _ ByVal pastreamcallbackflags As Byte, _ ByVal userdata As Byte) As Integer ' do clever things here End Function The external function in the dll is called with err = Pa_OpenStream( ptr, _ nulthing, _ outputParameters, _ SAMPLE_RATE, _ FRAMES_PER_BUFFER, _ clipoff, _ AddressOf MyCallback, _ dataptr) This is broken in the declaration of the external function - it doesn't like the type IntPtr as a function pointer for AddressOf. Can anyone show me how to implement passing this callback function please ? Many thanks David

  • how to extend a protocol for a delegate in objective C, then subclass an object to require a conform

    - by fess .
    I want to subclass UITextView, and send a new message to the delegate. So, I want to extend the delegate protocol, What's the correct way to do this? I started out with this: interface: #import <Foundation/Foundation.h> @class MySubClass; @protocol MySubClassDelegate <UITextViewDelegate> - (void) MySubClassMessage: (MySubClass *) subclass; @end @interface MySubClass : UITextView { } @end implementation: #import "MySubClass.h" @implementation MySubClass - (void) SomeMethod; { if ([self.delegate respondsToSelector: @selector (MySubClassMessage:)]) { [self.delegate MySubClassMessage: self]; } } @end however with that I get the warning: '-MySubClassMessage:' not found in protocol(s). I had one way working where I created my own ivar to store the delegate, then also stored the delegate using [super setDelegate] but that seemed wrong. perhaps it's not. I know I can just pass id's around and get by, but My goal is to make sure that the compiler checks that any delegate supplied to MySubClass conforms to MySubClassDelegate protocol. To further clairfy: @interface MySubClassTester : NSObject { } @implementation MySubClassTester - (void) one { MySubClass *subclass = [[MySubClass alloc] init]; subclass.delegate = self; } @end will produce the warning: class 'MySubClassTester' does not implement the 'UITextViewDelegate' protocol I want it to produce the warning about not implementing 'MySubClassDelegate' protocol instead. Thanks, a bunch. (thanks brad)

  • Help to understand the issue with protected method

    - by zeroed
    I'm reading Sybex Complete Java 2 Certification Study Guide April 2005 (ISBN0782144195). This book is for java developers who wants to pass java certification. After a chapter about access modifiers (along with other modifiers) I found the following question (#17): True or false: If class Y extends class X, the two classes are in different packages, and class X has a protected method called abby(), then any instance of Y may call the abby() method of any other instance of Y. This question confused me a little. As far as I know you can call protected method on any variable of the same class (or subclasses). You cannot call it on variables, that higher in the hierarchy than you (e.g. interfaces that you implement). For example, you cannot clone any object just because you inherit it. But the questions says nothing about variable type, only about instance type. I was confused a little and answered "true". The answer in the book is False. An object that inherits a protected method from a superclass in a different package may call that method on itself but not on other instances of the same class. There is nothing here about variable type, only about instance type. This is very strange, I do not understand it. Can anybody explain what is going on here?

  • Sqlite3 "chained" query

    - by Arrieta
    I need to create a configuration file from a data file that looks as follows: MAN1_TIME '01-JAN-2010 00:00:00.0000 UTC' MAN1_RX 123.45 MAN1_RY 123.45 MAN1_RZ 123.45 MAN1_NEXT 'MAN2' MAN2_TIME '01-MAR-2010 00:00:00.0000 UTC' MAN2_RX 123.45 [...] MAN2_NEXT 'MANX' [...] MANX_TIME [...] This file describes different "legs" of a trajectory. In this case, MAN1 is chained to MAN2, and MAN2 to MANX. In the original file, the chains are not as obvious (i.e., they are non-sequential). I've managed to read the file and store in an Sqlite3 database (I'm using the Python interface). The table is stored with three columns: Id, Par, and Val; for instance, Id='MAN1', Par='RX', and Val='123.45'. I'm interested in querying such database for obtaining the information related to 'n' legs. In English, that would be: "Select RX,RY,RZ for the next five legs starting on MAN1" So the query would go to MAN1, retrieve RX, RY, RZ, then read the parameter NEXT and go to that Id, retrieve RX, RY, RZ; read the parameter NEXT; go to that one ... like this five times. How can I pass such query with "dynamic parameters"? Thank you.

  • DropDownListFor and relating my lambda to my ViewModel

    - by Daniel Harvey
    After googling for a while I'm still drawing a blank here. I'm trying to use a ViewModel to pull and provide a dictionary to a drop down list inside a strongly typed View: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="Notebook.ViewModels.CorporationJoinViewModel" %> ... <%: Html.DropDownListFor(c => c.CorpDictionary.Keys, new SelectList(Model.CorpDictionary, "Value", "Key"))%> I'm getting the error CS1061: 'object' does not contain a definition for 'CorpDictionary' and no extension method 'CorpDictionary' accepting a first argument of type 'object' could be found and the relevant bit of my ViewModel public class CorporationJoinViewModel { DB _db = new DB(); // data context public Dictionary<int, string> CorpDictionary { get { Dictionary<int, string> corporations = new Dictionary<int, string>(); int x = 0; foreach (Corporation corp in _db.Corporations) { corporations.Add(x, corp.name); } return corporations; } } I'll admit i have a pretty magical understanding of how linq is finding my ViewModel object from that lambda, and the error message is making me think it's not. Is my problem the method I'm using to pass the data? What am I missing here?

  • 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.

  • How to use Java varargs with the GWT Javascript Native Interface? (aka, "GWT has no printf()")

    - by markerikson
    I'm trying to quickly learn GWT as part of a new project. I found out that GWT doesn't implement Java's String.format() function, so there's no printf()-like functionality. I knew that some printf() implementations exist for Javascript, so I figured I could paste one of those in as a GWT Javascript Native Interface function. I ran into problems, and decided I'd better make sure that the varargs values were being passed in correctly. That's where things got ugly. First, some example code: // From Java, call the JSNI function: test("sourceString", "params1", "params2", "params3"); .... public static native void test(Object... params) /*-{ // PROBLEM: this kills GWT! // alert(params.length); // returns "function" alert(typeof(params)); // returns "[Ljava.lang.Object;@b97ff1" alert(params); }-*/; The GWT docs state that "calling a varargs JavaScript method from Java will result in the callee receiving the arguments in an array". I figured that meant I could at least check params.length, but accessing that throws a JavascriptException wrapped in an UmbrellaException, with no real information. When I do "typeof(params)", it returns "function". As if that weren't odd enough, if I check the string value of params, it returns what appears to be a string version of a Java reference. So, I guess I'm asking a few different questions here: 1) How do GWT/JSNI varargs actually work, and do I need to do something special to pass in values? 2) What is actually going on here? 3) Is there any easier way to get printf()-style formatting in a GWT application?

  • What should i do to test EasyMock objects when using Generics ? EasyMock

    - by Arthur Ronald F D Garcia
    See code just bellow Our generic interface public interface Repository<INSTANCE_CLASS, INSTANCE_ID_CLASS> { void add(INSTANCE_CLASS instance); INSTANCE_CLASS getById(INSTANCE_ID_CLASS id); } And a single class public class Order { private Integer id; private Integer orderNumber; // getter's and setter's public void equals(Object o) { if(o == null) return false; if(!(o instanceof Order)) return false; // business key if(getOrderNumber() == null) return false; final Order other = (Order) o; if(!(getOrderNumber().equals(other.getOrderNumber()))) return false; return true; } // hashcode } And when i do the following test private Repository<Order, Integer> repository; @Before public void setUp { repository = EasyMock.createMock(Repository.class); Order order = new Order(); order.setOrderNumber(new Integer(1)); repository.add(order); EasyMock.expectLasCall().once(); EasyMock.replay(repository); } @Test public void addOrder() { Order order = new Order(); order.setOrderNumber(new Integer(1)); repository.add(order); EasyMock.verify(repository) } I get Unexpected method call add(br.com.smac.model.domain.Order@ac66b62): add(br.com.smac.model.domain.Order@ac66b62): expected: 1, actual: 0 Why does it not work as expected ??? What should i do to pass the test ???

  • Dynamic Google Maps API InfoWindow HTML Content

    - by Peter Hanneman
    I am working in Flash Builder 4 with Google Map's ActionScript API. I have created a map, loaded some custom markers onto it and added some MouseEvent listeners to each marker. The trouble comes when I load an InfoWindow panel. I want to dynamically set the htmlContent based off of information stored in a database. The trouble is that this information can change every couple of seconds and each marker has a unique data set so I can not statically set it at the time I actually create the markers. I have a method that will every minute or so load all of the records from my database into an Object variable. Everything I need to display in the htmlContent is contained in this object under a unique identifier. The basic crux of the problem is that there is no way for me to uniquely identify an info window, so I can not determine what information to pull into the panel. marker.addEventListener(MapMouseEvent.ROLL_OVER, function(e:MapMouseEvent):void { showInfoWindow(e.latLng) }, false, 0, false); That is my mouse event listener. The function I call, "showInfowindow" looks like this: private function showInfoWindow(latlng:LatLng):void { var options:InfoWindowOptions = new InfoWindowOptions({title: appData[*I NEED A UNIQUE ID HERE!!!*].type + " Summary", contentHTML: appData[*I NEED A UNIQUE ID HERE!!!*].info}); this.map.openInfoWindow(latlng, options); } I thought I was onto something by being able to pass a variable in my event listener declaration, but it simply hates having a dynamic variable passed through, it only returns the last value use. Example: marker.addEventListener(MapMouseEvent.ROLL_OVER, function(e:MapMouseEvent):void { showInfoWindow(e.latLng, record.unit_id) }, false, 0, false); That solution is painfully close to working. I iterate through a loop to create my markers when I try the above solution and roll over a marker I get information, but every marker's information reflects whatever information the last marker created had. I apologize for the long explaination but I just wanted to make my question as clear as possible. Does anyone have any ideas about how to patch up my almost-there-solution that I posted at the bottom or any from the ground up solutions? Thanks in advance, Peter Hanneman

  • Generic function pointers in C

    - by Lucas
    I have a function which takes a block of data and the size of the block and a function pointer as argument. Then it iterates over the data and performes a calculation on each element of the data block. The following is the essential outline of what I am doing: int myfunction(int* data, int size, int (*functionAsPointer)(int)){ //walking through the data and calculating something for (int n = 0; n < size; n++){ data[n] = (*function)(data[n]); } } The functions I am passing as arguments look something like this: int mycalculation(int input){ //doing some math with input //... return input; } This is working well, but now I need to pass an additional variable to my functionpointer. Something along the lines int mynewcalculation(int input, int someVariable){ //e.g. input = input * someVariable; //... return input; } Is there an elegant way to achieve this and at the same time keeping my overall design idea?

  • How can UISearchDisplayController autorelease cause crash in a different view controller?

    - by Tofrizer
    Hi, I have two view controllers A and B. From A, I navigate to view controller B as follows: // in View Controller A // navigateToB method -(void) navigateToB { BViewController *bViewController = [[BViewController alloc] initWithNibName: @"BView" bundle:nil]; bViewController.bProperty1 = SOME_STRING_CONSTANT; bViewController.title = @"A TITLE OF A VC's CHOOSING"; [self.navigationController pushViewController: bViewController animated:YES]; [bViewController release]; //<----- releasing 0x406c1e0 } In BViewController, the property bPropery1 is defined with copy as below (note, B also contains UITableView and other properties): @property (nonatomic, copy) NSString *bProperty1; Everything appeared to work fine when navigating back and forth between A and B. That is until I added a UISearchDisplayController to the table view contained in BViewController. Now when I navigate out of B, back to A, the app crashes. Stack trace shows what looks the search display controller being autoreleased at time of crash: #0 0x009663a7 in ___forwarding___ #1 0x009426c2 in __forwarding_prep_0___ #2 0x018c8539 in -[UISearchDisplayController _destroyManagedTableView] #3 0x018c8ea4 in -[UISearchDisplayController dealloc] #4 0x00285ce5 in NSPopAutoreleasePool NSZombies shows: -[BViewController respondsToSelector:]: message sent to deallocated instance 0x406c1e0 And malloc history on this points to the bViewController already released in A's navigateToB method above: Call [2] [arg=132]: thread_a065e720 |start ... <snip> ..._sendActionsForEvents:withEvent:] | -[UIControl sendAction:to:forEvent:] | - [UIApplication sendAction:to:from:forEvent:] | -[**AViewController navigateToB**] | +[NSObject alloc] | +[NSObject allocWithZone:] | _internal_class_createInstance | _internal_class_createInstanceFromZone | calloc | malloc_zone_calloc Can someone please give me any ideas on what is happening here? In navigateToB method, once the bViewController is released (after pushViewController), that's should be it for bViewController. Nothing else even knows about it as it is local to the navigateToB method block and it has been released. When navigating from B back to A, nothing is invoked in viewDidLoad, viewWillAppear etc that will re-enter navigateToB. It looks like somehow search display controller has a reference to something in my AViewController and so as it is autoreleased it is taking this "something" down with it but I cannot understand how this is possible, especially as I'm using copy to pass data between A and B. I'm going potty over this. I'm sure this is my mistake somewhere and so I turn to you, Stack Overflow legends for any words of wisdom or advice on how to resolve this. Many Thanks.

  • Validation in n-tier asp.net mvc applications

    - by sTodorov
    Dear Stack Overflow gurus, I am looking for some practical/theoretical information regarding best practices for validation in asp.net mvc n-tier applications. I am working on a .Net application divided into the following layers: UI - Mvc3 BLL layer - all business rules. Decoupled from data access and UI layers through interfaces DAL layer - Data access with the repository pattern, EF4 and pocos Now, I am looking for a nice, clean and transparent way to specify my validation rules. Here are some thoughts on the matter so far: UI validation should only be responsible for user input and its validity. BLL validation should be handling the validity of the data regarding the application business rules. My main concern is how to bind the BLL and UI validation in the most efficient way. One think I am would like to avoid is having the UI check in a collection of validation and adding manually errors to the ModelState. Furthermore, I do not want to pass the ModelState to the BLL to be populated in there. I will appreciate any thoughts on the matter. P.S. Should this question be marked as a discussion ?
