  • WCF service with PHP client - complex type as parameter not working

    - by Matt F
    Hi, I have a WCF service with three methods. Two of the methods return custom types (these work as expected), and the third method takes a custom type as a parameter and returns a boolean. When calling the third method via a PHP soap client it returns an 'Object reference not set to an instance of an object' exception. Example Custom Type: _ Public Class MyClass Private _propertyA As Double <DataMember()> _ Public Property PropertyA() As Double Get Return _propertyA End Get Set(ByVal value As Double) _propertyA = value End Set End Property Private _propertyB As Double <DataMember()> _ Public Property PropertyB() As Double Get Return _propertyB End Get Set(ByVal value As Double) _propertyB = value End Set End Property Private _propertyC As Date <DataMember()> _ Public Property PropertyC() As Date Get Return _propertyC End Get Set(ByVal value As Date) _propertyC = value End Set End Property End Class Method: Public Function Add(ByVal param As MyClass) As Boolean Implements IService1.Add ' ... End Function PHP client call: $client-Add(array('param'=array( 'PropertyA' = 1, 'PropertyB' = 2, 'PropertyC' = "2009-01-01" ))); The WCF service works fine with a .Net client but I'm new to PHP and can't get this to work. Is it possible to create an instance of 'MyClass' in PHP. Any help would be appreciated. Note: I'm using PHP 5 (XAMPP 1.7.0 for Windows). Thanks Matt

  • Precision error on matrix multiplication

    - by Wam
    Hello all, Coding a matrix multiplication in my program, I get precision errors (inaccurate results for large matrices). Here's my code. The current object has data stored in a flattened array, row after row. Other matrix B has data stored in a flattened array, column after column (so I can use pointer arithmetic). protected double[,] multiply (IMatrix B) { int columns = B.columns; int rows = Rows; int size = Columns; double[,] result = new double[rows,columns]; for (int row = 0; row < rows; row++) { for (int col = 0; col < columns; col++) { unsafe { fixed (float* ptrThis = data) fixed (float* ptrB = B.Data) { float* mePtr = ptrThis + row*rows; float* bPtr = ptrB + col*columns; double value = 0.0; for (int i = 0; i < size; i++) { value += *(mePtr++) * *(bPtr++); } result[row, col] = value; } } } } } Actually, the code is a bit more complicated : I do the multiply thing for several chunks (so instead of having i from 0 to size, I go from localStart to localStop), then sum up the resulting matrices. My problem : for a big matrix I get precision error : NUnit.Framework.AssertionException: Error at (0,1) expected: <6.4209571409444209E+18> but was: <6.4207619776304906E+18> Any idea ?

  • How do I read text from a serial port?

    - by user2164
    I am trying to read data off of a Windows serial port through Java. I have the javax.comm libraries and am able to get some data but not correct data. When I read the port into a byte array and convert it to text I get a series of characters but no real text string. I have tried to specify the byte array as being both "UTF-8" and "US-ASCII". Does anyone know how to get real text out of this? Here is my code: while (inputStream.available() > 0) { int numBytes = inputStream.read(readBuffer); System.out.println("Reading from " + portId.getName() + ": "); System.out.println("Read " + numBytes + " bytes"); } System.out.println(new String(readBuffer)); System.out.println(new String(readBuffer, "UTF-8")); System.out.println(new String(readBuffer, "US-ASCII")); the output of the first three lines will not let me copy and paste (I assume because they are not normal characters). Here is the output of the Hex: 78786000e67e9e60061e8606781e66e0869e98e086f89898861878809e1e9880 I am reading from a Hollux GPS device which does output in string format. I know this for sure because I did it through C#. The settings that I am using for communication which I know are right from the work in the C# app are: Baud Rate: 9600 Databits: 8 Stop bit: 1 parity: none

  • Zend_Validate_Abstract custom validator not displaying correct error messages.

    - by Jeremy Dowell
    I have two text fields in a form that I need to make sure neither have empty values nor contain the same string. The custom validator that I wrote extends Zend_Validate_Abstract and works correctly in that it passes back the correct error messages. In this case either: isEmpty or isMatch. However, the documentation says to use addErrorMessages to define the correct error messages to be displayed. in this case, i have attached ->addErrorMessages(array("isEmpty"=>"foo", "isMatch"=>"bar")); to the form field. According to everything I've read, if I return "isEmpty" from isValid(), my error message should read "foo" and if i return "isMatch" then it should read "bar". This is not the case I'm running into though. If I return false from is valid, no matter what i set $this-_error() to be, my error message displays "foo", or whatever I have at index[0] of the error messages array. If I don't define errorMessages, then I just get the error code I passed back for the display and I get the proper one, depending on what I passed back. How do I catch the error code and display the correct error message in my form? The fix I have implemented, until I figure it out properly, is to pass back the full message as the errorcode from the custom validator. This will work in this instance, but the error message is specific to this page and doesn't really allow for re-use of code. Things I have already tried: I have already tried validator chaining so that my custom validator only checks for matches: ->setRequired("true") ->addValidator("NotEmpty") ->addErrorMessage("URL May Not Be Empty") ->addValidator([*customValidator]*) ->addErrorMessage("X and Y urls may not be the same") But again, if either throws an error, the last error message to be set displays, regardless of what the error truly is. I'm not entirely sure where to go from here. Any suggestions?

  • Images from SQL Server JPG/PNG Image Column not being Type Converted to Bitmap in HttpHandlers (cons

  • How to loop video using NetStream in Data Generation Mode

    - by WesleyJohnson
    I'm using a NetStream in Data Generation Mode to play an embeded FLV using appendBytes. When the stream is finished playing, I'd like to loop the FLV file. I'm not sure how to achieve this. Here is what I have so far (this isn't a complete example): public function createBorderAnimation():void { // Load the skin image borderAnimation = Assets.BorderAnimation; // Convert the animation to a byte array borderAnimationBytes = new borderAnimation(); // Initialize the net connection border_nc = new NetConnection(); border_nc.connect( null ); // Initialize the net stream border_ns = new NetStream( border_nc ); border_ns.client = { onMetaData:function( obj:Object ):void{ trace(obj); } } border_ns.addEventListener( NetStatusEvent.NET_STATUS, border_netStatusHandler ); border_ns.play( null ); border_ns.appendBytes( borderAnimationBytes ); // Initialize the animation border_vd = new Video( 1024, 768 ); border_vd.attachNetStream( border_ns ); // Add the animation to the stage ui = new UIComponent(); ui.addChild( DisplayObject( border_vd ) ); grpBackground.addElement( ui ); } protected function border_netStatusHandler( event:NetStatusEvent ):void { if( event.info.code == "NetStream.Buffer.Flush" || event.info.code == "NetStream.Buffer.Empty" ) { border_ns.appendBytesAction( NetStreamAppendBytesAction.RESET_BEGIN ); border_ns.appendBytes( borderAnimationBytes ); border_ns.appendBytesAction( NetStreamAppendBytesAction.END_SEQUENCE ); } } This will loop the animation, but it starts chewing up memory like crazy. I've tried using NetStream.seek(0) and NetStream.appendBytesAction( NetStreamAppendBytesAction.RESET_SEEK ), but then I'm not sure what to do next. If you just try to call appendBytes again after that, it doesn't work, presumably because I'm appending the full byte array which has the FLV header and stuff? I'm not very familiar with how that all works. Any help is greatly appreciated.

  • Subclassing NSArrayController in order to limit size of arrangedObjects

    - by Simone Manganelli
    I'm trying to limit the number of objects in an array controller, but I still want to be able to access the full array, if necessary. A simple solution I came up with was to subclass NSArrayController, and define a new method named "limitedArrangedObjects", that returns a limited number of objects from the real set of arranged objects. (I've seen http://stackoverflow.com/questions/694493/limiting-the-number-of-objects-in-nsarraycontroller , but that doesn't address my problem.) I want this property to be observable via bindings, so I set a dependency to arrangedObjects on it. Problem is, when arrangedObjects is updated, limitedArrangedObjects seems not to be observing the value change in arrangedObjects. I've hooked up an NSCollectionView to limitedArrangedObjects, and zero objects are being displayed. (If I bind it to arrangedObjects instead, all the objects show up as expected.) What's the problem? Here's the relevant code: @property (readonly) NSArray *limitedArrangedObjects; - (NSArray *)limitedArrangedObjects; { NSArray *arrangedObjects = [super arrangedObjects]; NSUInteger upperLimit = 10000; NSUInteger count = [arrangedObjects count]; if (count > upperLimit) count = upperLimit; arrayToReturn = [arrangedObjects subarrayWithRange:NSMakeRange(0, count)]; return arrayToReturn; } + (NSSet *)keyPathsForValuesAffectingValueForKey:(NSString *)key; { NSSet *keyPaths = [super keyPathsForValuesAffectingValueForKey:key]; if ([key isEqualToString:@"limitedArrangedObjects"]) { NSSet *affectingKeys = [NSSet setWithObjects:@"arrangedObjects",nil]; keyPaths = [keyPaths setByAddingObjectsFromSet:affectingKeys]; } return keyPaths; }

  • Help Modifying Generic REST Helper PHP Example Code to Support XML DOM

    - by Jennifer Baker
    Hi! I found this example PHP source code at HTTP POST from PHP, without cURL I need some help modifying the example PHP source to support XML DOM for manipulating a REST API. I thought that if I update the CASE statement for the XML section below from $r = simplexml_load_string($res); to $r = new DOMDocument(); $r->load($res); that it would work but it doesn't. :( Any help would be appreciated. function rest_helper($url, $params = null, $verb = 'GET', $format = 'xml') { $cparams = array( 'http' => array( 'method' => $verb, 'ignore_errors' => true ) ); if ($params !== null) { $params = http_build_query($params); if ($verb == 'POST') { $cparams['http']['content'] = $params; } else { $url .= '?' . $params; } } $context = stream_context_create($cparams); $fp = fopen($url, 'rb', false, $context); if (!$fp) { $res = false; } else { // If you're trying to troubleshoot problems, try uncommenting the // next two lines; it will show you the HTTP response headers across // all the redirects: // $meta = stream_get_meta_data($fp); // var_dump($meta['wrapper_data']); $res = stream_get_contents($fp); } if ($res === false) { throw new Exception("$verb $url failed: $php_errormsg"); } switch ($format) { case 'json': $r = json_decode($res); if ($r === null) { throw new Exception("failed to decode $res as json"); } return $r; case 'xml': $r = simplexml_load_string($res); if ($r === null) { throw new Exception("failed to decode $res as xml"); } return $r; } return $res; }

  • Conditional Join - join 1 tables 2 ways

    - by Jon H
    I have a set of (not very well normalised or relational) tables named PLAN, GROUP, PRODUCT CLIENT Most have linkage i.e. PLAN - CLIENT on clno GROUP to PRODUCT on PRODCD However, the linkage between PLAN and GROUP is tricky. A plan has 2 field of interest GRPNO and PRODCD. What I want to do is if GRPNO != 0 then join GROUP on GRPNO. However if GRPNO = 0 then I want to join GROUP on PRODCD. The frustrating thing is that the fileds I want to return in my queries are the same across the board I just need to be able to vary the join, or join the same table twice. The best I can come up with is 2 queries and merge them using datasets, or possibly using a union. Is there a nifty way to do this in one select? I should point out I am access Foxpro over ODBC to do this. Thank you!

  • How can I force PHP's fopen() to return the current version of a web page?

    - by Edward Tanguay
    The current content of this google docs page is: However, when reading this page with the following PHP fopen() script, I get an older, cached version: I've tried two solutions proposed in this question (a random attribute and using POST) and I also tried clearstatcache() but I always get the cached version of the web page. What do I have to change in the following script so that fopen() returns the current version of the web page? <?php $url = 'http://docs.google.com/View?id=dc7gj86r_32g68627ff&amp;rand=' . getRandomDigits(10); echo $url .

  • Trouble adding video controls to video selected by XML comboBox

    - by user560128
    Hello, it's been a few years since I've touched flash, so perhaps I'm just overlooking something. If anyone could look at the code and offer any suggestions that would be awesome. What's working, I select a video from a combobox that is populated from an XML file, pick the video and it plays. I've been trying to add pause/play, stop, forward and reverse functionality, once I get that to work I also want to add a video scrubber(slider), and previous/next buttons to go to the previous/next video as listed in the xml file. At the moment I have a component button on the stage called playButton, which I'm trying to use for pause/play functionality. Below is my code, the player control is at the very bottom. Thanks. import fl.data.DataProvider; var nc:NetConnection = new NetConnection(); nc.connect(null); var ns:NetStream = new NetStream(nc); var videosXML:XML = new XML(); var loader:URLLoader = new URLLoader(); var request:URLRequest= new URLRequest("xml/videos.xml"); var videos:Array = new Array({label:"Select a Video",data:""}); var client:Object = new Object(); theVideo.attachNetStream(ns); ns.client = client; loader.addEventListener(Event.COMPLETE,loaderOnComplete); loader.load (request); function loaderOnComplete(event:Event):void{ videosXML = new XML(event.target.data); for each (var video:XML in videosXML.video){ videos.push({label:video.name.toString(),data:video.url.toString()}); } moviesCB.dataProvider = new DataProvider(videos); } moviesCB.addEventListener(Event.CHANGE, changeHandler); function changeHandler(event:Event):void { if(ComboBox(event.target).selectedItem.data != ""){ ns.play(ComboBox(event.target).selectedItem.data); } }; client.onMetaData = metadataHandler; function metadataHandler(md:Object):void{ } //player controls playButton.onRelease = function() { ns.pause(); }

  • Confused about definition of a 'median' when constructing a kd-Tree

    - by user352636
    Hi there. Im trying to build a kd-tree for searching through a set of points, but am getting confused about the use of 'median' in the wikipedia article. For ease of use, the wikipedia article states the pseudo-code of kd-tree construction as: function kdtree (list of points pointList, int depth) { if pointList is empty return nil; else { // Select axis based on depth so that axis cycles through all valid values var int axis := depth mod k; // Sort point list and choose median as pivot element select median by axis from pointList; // Create node and construct subtrees var tree_node node; node.location := median; node.leftChild := kdtree(points in pointList before median, depth+1); node.rightChild := kdtree(points in pointList after median, depth+1); return node; } } I'm getting confused about the "select median..." line, simply because I'm not quite sure what is the 'right' way to apply a median here. As far as I know, the median of an odd-sized (sorted) list of numbers is the middle element (aka, for a list of 5 things, element number 3, or index 2 in a standard zero-based array), and the median of an even-sized array is the sum of the two 'middle' elements divided by two (aka, for a list of 6 things, the median is the sum of elements 3 and 4 - or 2 and 3, if zero-indexed - divided by 2.). However, surely that definition does not work here as we are working with a distinct set of points? How then does one choose the correct median for an even-sized list of numbers, especially for a length 2 list? I appreciate any and all help, thanks! -Stephen

  • Help setup my .git/config file for Heroku AND my Unfuddle Account

    - by 05WRXSTi
    Ok, I have three different computers that I work from and right now their configurations are all different so I have to push/pull a certain on each and its very bothersome. What I want to do is have ONE config file that I can use for all three that will allow me to do the following: git push unfuddle git pull heroku git push unfuddle git pull heroku And I'm new to git, so I know that maybe I need heroku master or 'heroku origin` or somethign? Here is what my config file looks like right now: [core] repositoryformatversion = 0 filemode = true bare = false logallrefupdates = true [remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* url = [email protected]:HEROKU-APP.git [branch "master"] remote = origin merge = refs/heads/master [remote "unfuddle"] fetch = +refs/heads/*:refs/remotes/origin/* url = [email protected]:UNFUDDLE-APP/UNFUDDLE-APP.git obviously the git urls were changed to protect the innocent. What should I change so that I can easily push and pull to/from both of these repos? Thanks!

  • git merging changes to local branch

    - by ScottS
    Is it possible to merge changes from a central repo to a local branch without having to commit/stash the edits on the local branch and checkout master? If I am working on local branch "work" and there are some uncommited changes, I use the following steps to get updates from the central repo into my working branch. git stash git checkout master git pull git checkout work git rebase master git stash pop Usually there are no uncommitted changes in "work" and then I omit the stash steps. What I would really like is something like the following: git pull master (updates master while work branch is checked out and has changes) git rebase master (rebases the updates into work branch uncommited changes are still safe) Is there something easier than what I currently do?

  • what's faster: merging lists or dicts in python?

    - by tipu
    I'm working with an app that is cpu-bound more than memory bound, and I'm trying to merge two things whether they be sets or dicts. Now the thing is i can choose either one, but I'm wondering if merging dicts would be faster since it's all in memory? Or is it always going to be O(n), n being the size of the smaller set. The reason I asked about dicts rather than sets is because I can't convert a set to json, because that results in {key1, key2, key3} and json needs a key/value pair, so I am using a dict so json dumps returns {key1:1, key2:1, key3:1}. Yes this is wasteful, but if it proves to be faster then I'm okay with it.

  • How to load JPG file into NSBitmapImageRep?

    - by Adam
    Objective-C / Cocoa: I need to load the image from a JPG file into a two dimensional array so that I can access each pixel. I am trying (unsuccessfully) to load the image into a NSBitmapImageRep. I have tried several variations on the following two lines of code: NSString *filePath = [NSString stringWithFormat: @"%@%@",@"/Users/adam/Documents/phoneimages/", [outLabel stringValue]]; //this coming from a window control NSImageRep *controlBitmap = [[NSImageRep alloc] imageRepWithContentsOfFile:filePath]; With the code shown, I get a runtime error: -[NSImageRep imageRepWithContentsOfFile:]: unrecognized selector sent to instance 0x100147070. I have tried replacing the second line of code with: NSImage *controlImage = [[NSImage alloc] initWithContentsOfFile:filePath]; NSBitmapImageRep *controlBitmap = [[NSBitmapImageRep alloc] initWithData:controlImage]; But this yields a compiler error 'incompatible type' saying that initWithData wants a NSData variable not an NSImage. I have also tried various other ways to get this done, but all are unsuccessful either due to compiler or runtime error. Can someone help me with this? I will eventually need to load some PNG files in the same way (so it would be nice to have a consistent technique for both). And if you know of an easier / simpler way to accomplish what I am trying to do (i.e., get the images into a two-dimensional array), rather than using NSBitmapImageRep, then please let me know! And by the way, I know the path is valid (confirmed with fileExistsAtPath) -- and the filename in outLabel is a file with .jpg extension. Thanks for any help!

  • Extending configuration for .Net 3.5 Applications

    - by Maximiliano Rios
    Due to a requirement in my current project, I have to build a configuration manager to handle configurations that merge local config info with database one. Custom configuration doesn't fit my needs, problem is that I don't know what's the type before loading certain information, for example: Loading database information I will able to know what's myhandler's type. Not previously. So I thought to write my own handler but I can't let set blank as type for sections, in fact .net requires to know what's the type to match myhandler nodes. I'm thinking on building a different parser to read XML nodes but I would prefer to match this structure. I've not found any information to do that yet, is there any way? Can I extend or hook up something into the framework to be capable of loading on-the-fly types and validate nodes? Thanks in advance.

  • Foreach loop returning null values in PHP?

    - by Jascha
    Hello, I have a pretty simple problem. Basically I have an array called $list that is a list of titles. If I do a print_r($list) I get these results: Array ( [0] => Another New Title [1] => Awesome Movies and stuff [2] => Jascha's Title ) Now, I'm running a foreach loop to retrieve their values and format them in an <ul> like so... function get_film_list(){ global $categories; $list = $categories->get_film_list(); if(count($list)==0){ echo 'No films are in this category'; }else{ echo '<ul>'; foreach($list as $title){ echo '<li>' . $title . '<li>'; } echo '</ul>'; } } The problem I'm having is my loop is returning two values per value (is it the key value?) The result of the preceding function looks like this: Another New Title   Awesome Movies and stuff   Jascha's Title   I even tried: foreach($list as $key => $title){ echo '<li>' . $title . '<li>'; } With the same results: Another New Title   Awesome Movies and stuff   Jascha's Title   What am I missing here? Thanks in advance.

  • Adding a date every few days

    I have some code that generates fixtures, I am looking to add a fixture date to the code. $totalRounds = $teams - 1; $matchesPerRound = $teams / 2; $rounds = array(); for ($i = 0; $i < $totalRounds; $i++) { $rounds[$i] = array(); } for ($round = 0; $round < $totalRounds; $round++) { for ($match = 0; $match < $matchesPerRound; $match++) { $home = ($round + $match) % ($teams - 1); $away = ($teams - 1 - $match + $round) % ($teams - 1); // Last team stays in the same place while the others // rotate around it. if ($match == 0) { $away = $teams - 1; } $rounds[$round][$match] = "$user[$home]~$team[$home]@$user[$away]~$team[$away]"; } } $team is the amount of teams in the league. I want to add a variable for every 4 days, and for every round of fixtures generated, I want to add 4 days onto the previous round. For example, if today is 3rd may, i want 3rd may for first fixture, 7th may for second fixture, 11th may for third fixture. By fixture i mean round which includes a set of fixtures!

Here's what I've got private function loadData():void{ var stmt:SQLStatement = new SQLStatement(); stmt.sqlConnection = sqlConn; stmt.text = "SELECT * FROM tbl_user ORDER BY user_id ASC"; stmt.execute(); var result:SQLResult = stmt.getResult(); acData = new ArrayCollection(result.data); } <mx:TileList id="userlist" labelField="user_id" dataProvider="{acData}" width="600" height="200" paddingTop="25" left="117.15" y="327.25"> <!--itemClick="showMessage(event)"--> <mx:itemRenderer> <mx:Component> <mx:VBox width="125" height="125" paddingRight="5" paddingLeft="5" horizontalAlign="center"> <mx:Label id="username" text="{}"/> <mx:Label id="userjob" text="{}"/> </mx:VBox> </mx:Component> </mx:itemRenderer> </mx:TileList> So I'm just not sure how I go about pulling the information from the array and putting it into labels like username, userjob, userbio ect, Inside the TitleList and itemRenderer.

  • Multiplication of 2 positive numbers giving a negative result

    - by krandiash
    My program is an implementation of a bloom filter. However, when I'm storing my hash function results in the bit array, the function (of the form f(i) = (a*i + b) % m where a,b,i,m are all positive integers) is giving me a negative result. The problem seems to be in the calculation of a*i which is coming out to be negative. Ignore the print statements in the code; those were for debugging. Basically, the value of temp in this block of code is coming out to be negative and so I'm getting an ArrayOutOfBoundsException. m is the bit array length, z is the number of hash functions being used, S is the set of values which are members of this bloom filter and H stores the values of a and b for the hash functions f1, f2, ..., fz. public static int[] makeBitArray(int m, int z, ArrayList<Integer> S, int[] H) { int[] C = new int[m]; for (int i = 0; i < z; i++) { for (int q = 0; q < S.size() ; q++) { System.out.println(H[2*i]); int temp = S.get(q)*(H[2*i]); System.out.println(temp); System.out.println(S.get(q)); System.out.println(H[2*i + 1]); System.out.println(m); int t = ((H[2*i]*S.get(q)) + H[2*i + 1])%m; System.out.println(t); C[t] = 1; } } return C; } Any help is appreciated.

  • Javascript: Error 'Object Required.'

    - by javascripthelp
    The following is the error popup message I get when I click "Finalize" button on my website: "Line: 298 Char: 5 Error: Object required: 'lobi_c_selected(...)' Code: 0 URL: http://10.128.23.50/i-prostage/AP/w_ap_check_reconciliation.asp?" Normally, when I click "Finalize" button, it'll generate and show a report in a popup window. However, I'd get this error message instead.

  • Cast errors with IXmlSerializable

    - by Nathan
    I am trying to use the IXmlSerializable interface to deserialize an Object (I am using it because I need specific control over what gets deserialized and what does not. See my previous question for more information). However, I'm stumped as to the error message I get. Below is the error message I get (I have changed some names for clarity): An unhandled exception of type 'System.InvalidCastException' occurred in App.exe Additional information: Unable to cast object of type 'System.Xml.XmlNode[]' to type 'MyObject'. MyObject has all the correct methods defined for the interface, and regardless of what I put in the method body for ReadXml() I still get this error. It doesn't matter if it has my implementation code or if it's just blank. I did some googling and found an error that looks similar to this involving polymorphic objects that implement IXmlSerializable. However, my class does not inherit from any others (besides Object). I suspected this may be an issue because I never reference XmlNode any other time in my code. Microsoft describes a solution to the polymorphism error: https://connect.microsoft.com/VisualStudio/feedback/details/422577/incorrect-deserialization-of-polymorphic-type-that-implements-ixmlserializable?wa=wsignin1.0#details The code the error occurs at is as follows. The object to be read back in is an ArrayList of "MyObjects" IO::FileStream ^fs = gcnew IO::FileStream(filename, IO::FileMode::Open); array<System::Type^>^ extraTypes = gcnew array<System::Type^>(1); extraTypes[0] = MyObject::typeid; XmlSerializer ^xmlser = gcnew XmlSerializer(ArrayList::typeid, extraTypes); System::Object ^obj; obj = xmlser->Deserialize(fs); fs->Close(); ArrayList ^al = safe_cast<ArrayList^>(obj); MyObject ^objs; for each(objs in al) //Error occurs here { //do some processing } Thanks for reading and for any help.
