• Object Oriented Design Questions

  - by Robert

  Hello there. I am going to develop a Tic-Tac-Toe game using Java(or maybe other OO Languages).Now I have a picture in my mind about the general design. Interface: Player ,then I will be able to implement a couple of Player classes,based on how I want the opponent to be,for example,random player,intelligent player. Classes: Board class,with a two-dimensional array of integers,0 indicates open,1 indicates me,-1 indicates opponent.The evaluation function will be in here as well,to return the next best move based on the current board arrangement and whose turn it is. Refree class,which will create instance of the Board and two player instances,then get the game begin. This is a rough idea of my OO design,could anybody give me any critiques please,I find this is really beneficial,thank you very much.

• Calculate Matrix Rank using scipy

  - by Hooked

  I'd like to calculate the mathematical rank of a matrix using scipy. The most obvious function numpy.rank calculates the dimension of an array (ie. scalars have dimension 0, vectors 1, matrices 2, etc...). I am aware that the numpy.linalg.lstsq module has this capability, but I was wondering if such a fundamental operation is built into the matrix class somewhere. Here is an explicit example: from numpy import matrix, rank A = matrix([[1,3,7],[2,8,3],[7,8,1]]) print rank(A) This gives 2 the dimension, where I'm looking for an answer of 3.

• How to convert a JSON string to a Map<String, String> with Jackson JSON

  - by Infinity

  This is my first time trying to do something useful with Java.. I'm trying to do something like this but it doesn't work: Map<String, String> propertyMap = new HashMap<String, String>(); propertyMap = JacksonUtils.fromJSON(properties, Map.class); But the IDE says: 'Unchecked assignment Map to Map<String,String>' What's the right way to do this? I'm only using Jackson because that's what is already available in the project, is there a native Java way of converting to/from JSON? In PHP I would simply json_decode($str) and I'd get back an array. I need basically the same thing here. Thanks!

• SQL SERVER – Example of Performance Tuning for Advanced Users with DB Optimizer

  - by Pinal Dave

  Performance tuning is such a subject that everyone wants to master it. In beginning everybody is at a novice level and spend lots of time learning how to master the art of performance tuning. However, as we progress further the tuning of the system keeps on getting very difficult. I have understood in my early career there should be no need of ego in the technology field. There are always better solutions and better ideas out there and we should not resist them. Instead of resisting the change and new wave I personally adopt it. Here is a similar example, as I personally progress to the master level of performance tuning, I face that it is getting harder to come up with optimal solutions. In such scenarios I rely on various tools to teach me how I can do things better. Once I learn about tools, I am often able to come up with better solutions when I face the similar situation next time. A few days ago I had received a query where the user wanted to tune it further to get the maximum out of the performance. I have re-written the similar query with the help of AdventureWorks sample database. SELECT * FROM HumanResources.Employee e INNER JOIN HumanResources.EmployeeDepartmentHistory edh ON e.BusinessEntityID = edh.BusinessEntityID INNER JOIN HumanResources.Shift s ON edh.ShiftID = s.ShiftID; User had similar query to above query was used in very critical report and wanted to get best out of the query. When I looked at the query – here were my initial thoughts Use only column in the select statements as much as you want in the application Let us look at the query pattern and data workload and find out the optimal index for it Before I give further solutions I was told by the user that they need all the columns from all the tables and creating index was not allowed in their system. He can only re-write queries or use hints to further tune this query. Now I was in the constraint box – I believe * was not a great idea but if they wanted all the columns, I believe we can’t do much besides using *. Additionally, if I cannot create a further index, I must come up with some creative way to write this query. I personally do not like to use hints in my application but there are cases when hints work out magically and gives optimal solutions. Finally, I decided to use Embarcadero’s DB Optimizer. It is a fantastic tool and very helpful when it is about performance tuning. I have previously explained how it works over here. First open DBOptimizer and open Tuning Job from File >> New >> Tuning Job. Once you open DBOptimizer Tuning Job follow the various steps indicates in the following diagram. Essentially we will take our original script and will paste that into Step 1: New SQL Text and right after that we will enable Step 2 for Generating Various cases, Step 3 for Detailed Analysis and Step 4 for Executing each generated case. Finally we will click on Analysis in Step 5 which will generate the report detailed analysis in the result pan. The detailed pan looks like. It generates various cases of T-SQL based on the original query. It applies various hints and available hints to the query and generate various execution plans of the query and displays them in the resultant. You can clearly notice that original query had a cost of 0.0841 and logical reads about 607 pages. Whereas various options which are just following it has different execution cost as well logical read. There are few cases where we have higher logical read and there are few cases where as we have very low logical read. If we pay attention the very next row to original query have Merge_Join_Query in description and have lowest execution cost value of 0.044 and have lowest Logical Reads of 29. This row contains the query which is the most optimal re-write of the original query. Let us double click over it. Here is the query: SELECT * FROM HumanResources.Employee e INNER JOIN HumanResources.EmployeeDepartmentHistory edh ON e.BusinessEntityID = edh.BusinessEntityID INNER JOIN HumanResources.Shift s ON edh.ShiftID = s.ShiftID OPTION (MERGE JOIN) If you notice above query have additional hint of Merge Join. With the help of this Merge Join query hint this query is now performing much better than before. The entire process takes less than 60 seconds. Please note that it the join hint Merge Join was optimal for this query but it is not necessary that the same hint will be helpful in all the queries. Additionally, if the workload or data pattern changes the query hint of merge join may be no more optimal join. In that case, we will have to redo the entire exercise once again. This is the reason I do not like to use hints in my queries and I discourage all of my users to use the same. However, if you look at this example, this is a great case where hints are optimizing the performance of the query. It is humanly not possible to test out various query hints and index options with the query to figure out which is the most optimal solution. Sometimes, we need to depend on the efficiency tools like DB Optimizer to guide us the way and select the best option from the suggestion provided. Let me know what you think of this article as well your experience with DB Optimizer. Please leave a comment.

• Finding the problem on a partially succeeded build

  - by Martin Hinshelwood

  Now that I have the Build failing because of a genuine bug and not just because of a test framework failure, lets see if we can trace through to finding why the first test in our new application failed. Lets look at the build and see if we can see why there is a red cross on it. First, lets open that build list. On Team Explorer Expand your Team Project Collection | Team Project and then Builds. Double click the offending build. Figure: Opening the Build list is a key way to see what the current state of your software is.   Figure: A test is failing, but we can now view the Test Results to find the problem      Figure: You can quite clearly see that the test has failed with “The device is not ready”. To me the “The Device is not ready” smacks of a System.IO exception, but it passed on my local computer, so why not on the build server? Its a FaultException so it is most likely coming from the Service and not the client, so lets take a look at the client method that the test is calling: bool IProfileService.SaveDefaultProjectFile(string strComputerName) { ProjectFile file = new ProjectFile() { ProjectFileName = strComputerName + "_" + System.DateTime.Now.ToString("yyyyMMddhhmmsss") + ".xml", ConnectionString = "persist security info=False; pooling=False; data source=(local); application name=SSW.SQLDeploy.vshost.exe; integrated security=SSPI; initial catalog=SSWSQLDeployNorthwindSample", DateCreated = System.DateTime.Now, DateUpdated = System.DateTime.Now, FolderPath = @"C:\Program Files\SSW SQL Deploy\SampleData\", IsComplete=false, Version = "1.3", NewDatabase = true, TimeOut = 5, TurnOnMSDE = false, Mode="AutomaticMode" }; string strFolderPath = "D:\\"; //LocalSettings.ProjectFileBasePath; string strFileName = strFolderPath + file.ProjectFileName; try { using (FileStream fs = new FileStream(strFileName, FileMode.Create)) { DataContractSerializer serializer = new DataContractSerializer(typeof(ProjectFile)); using (XmlDictionaryWriter writer = XmlDictionaryWriter.CreateTextWriter(fs)) { serializer.WriteObject(writer, file); } } } catch (Exception ex) { //TODO: Log the exception throw ex; return false; } return true; } Figure: You can see on lines 9 and 18 that there are calls being made to specific folders and disks. What is wrong with this code? What assumptions mistakes could the developer have made to make this look OK: That every install would be to “C:\Program Files\SSW SQL Deploy” That every computer would have a “D:\\” That checking in code at 6pm because the had to go home was a good idea. lets solve each of these problems: We are in a web service… lets store data within the web root. So we can call “Server.MapPath(“~/App_Data/SSW SQL Deploy\SampleData”) instead. Never reference an explicit path. If you need some storage for your application use IsolatedStorage. Shelve your code instead. What else could have been done? Code review before check-in – The developer should have shelved their code and asked another dev to look at it. Use Defensive programming – Make sure that any code that has the possibility of failing has checks. Any more options? Let me know and I will add them. What do we do? The correct things to do is to add a Bug to the backlog, but as this is probably going to be fixed in sprint, I will add it directly to the sprint backlog. Right click on the failing test Select “Create Work Item | Bug” Figure: Create an associated bug to add to the backlog. Set the values for the Bug making sure that it goes into the right sprint and Area. Make your steps to reproduce as explicit as possible, but “See test” is valid under these circumstances.   Figure: Add it to the correct Area and set the Iteration to the Area name or the Sprint if you think it will be fixed in Sprint and make sure you bring it up at the next Scrum Meeting. Note: make sure you leave the “Assigned To” field blank as in Scrum team members sign up for work, you do not give it to them. The developer who broke the test will most likely either sign up for the bug, or say that they are stuck and need help. Note: Visual Studio has taken care of associating the failing test with the Bug. Save… Technorati Tags: WCF,MSTest,MSBuild,Team Build 2010,Team Test 2010,Team Build,Team Test

• Fastest way to access VB6 String in C#

  - by Simon Woods

  Hi I am using COMInterop. I have a call in VB6 which returns a string of roughly 13000 chars. If I execute the call in pure VB6 it takes about 800ms to execute. If I execute it via c# and COMInterop it takes about 8 seconds. I'm assuming the delay is caused by marshalling. If I am correct about marshalling, I'd be grateful if someone could suggest the fastest way I can get this into C#. e.g. Would it be better to a) expose it as a byte array b) provide a byref string param into the VB6 layer I would appreciate some sample code as well. I tried the Marshal.PtrToStringAuto(Marshal.ReadIntPtr(myCOMObject.GetString, 0) to no avail Many thx S

• Email attachment parsing via mime4j

  - by Ashish

  Hi, I am using a small java smtp library (http://code.google.com/p/subethasmtp/), by this I need to parse the incoming emails in separate components viz body, attachments etc. I am trying to use mime4j , but the documentation suggests that mime4j can only give event notification or token notification and nothing else. For stripping out body and attachments etc I had to use my own custom logic inside the event handlers. Is my observation correct? If yes then how can I use mime4j to use for my requirement. Please suggest. I badly need an approach that takes in the smtp data stream and returns me with an array of attachment references or streams in fully parsed out form in java. Please help. Thanks in advance Ashish Sharma

• Passing variable to Google Charts URL

  - by Rob A

  Hi All, This is probably something really simple, however I am quite new to PHP, and havent done any HTML in years. I need to get a PHP variable filled with an array of figures into Google Charts. My code for this so far is: <img src="http://chart.apis.google.com/chart? &chs=340x175 &chd=t:<?=$filedetail[1]?> &cht=lc &chtt=Test "> However, Google reports an error, as it stops at the ?=$filedetail[1] for some reason. It doesnt seem that reading the variable is the problem, more that the API simply cant read past the start of the PHP tags. Thanks, Rob A.

• Upgrading VSIX extensions from VS2012 to VS2013

  - by Tarun Arora [Microsoft MVP]

  Originally posted on: http://geekswithblogs.net/TarunArora/archive/2013/06/27/upgrading-vsix-extensions-from-vs2012-to-vs2013.aspx  As consumers of your Visual Studio extensions start to move over to VS 2013, you will have to upgrade the Visual Studio extensions you build for Visual Studio 2012 to Visual Studio 2013 and republish to the Visual Studio extension gallery. Failing which, it will not be possible for your consumers to install and use your extensions on Visual Studio 2013.   Objective In this blog post, I’ll show you how simple it is to upgrade your Visual Studio 2012 extension to Visual Studio 2013. There aren’t any reported breaking changes between VS 2012 SDK and VS 2013 SDK, the upgrade usually involves, rebuilding the extension against VS 2013 SDK and updating the vsix manifest file.              Walkthrough Download the Visual Studio 2013 SDK - You will need to download the Visual Studio 2013 SDK in order to open up the Visual Studio extension project in Visual Studio 2013. The SDK can be downloaded from here. Install the SDK before you proceed.                2. Once the VS 2013 SDK has been installed, open up your package project. For the purposes of this blog post, I’ll open up the Avanade Extension – Software Inventory in Visual Studio 2013. You will notice that Visual Studio doesn’t load the project but let’s you know that the project needs to be Migrated.                  3. Right click the project and choose the option ‘Reload Project’ from the Context Menu.                  4. Choosing the Reload Project option brings up an upgrade window, telling you that the upgrade is a one way only upgrade i.e. the project will be changed to work with Visual Studio 2013 and you will not be able to open the project up in Visual Studio 2012. My recommendation would be to create a Visual Studio 2013 branch and upgrading the project in that branch only, so if you need to go back to Visual Studio 2012 project at some point, you have a handy reference in a separate branch.             5. Upon clicking Ok, the project is updated. See below, the following changes are made at the time of upgrade,           - The runtime version is updated in the Resources.Designer.cs file                      - The Minimum version of Visual Studio in the package project file is changed from 11.0 to 12.0                    6. Reference VS 2013 dll’s rather than VS 2012 dll’s. So reference Microsoft.TeamFoundation.Client.dll and Microsoft.TeamFoundation.Controls.dll from C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v2.0 and C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v4.5. If you have any other API references, then change the references to point to VS 2013 instead of VS 2012.                          7. Rebuild your solution to ensure there are no breaking changes. Success!                8. Update VSIX Manifest file (the file source.extnsion.vsixmanifest contains the meta data for your VSIX).          - Update the Install Targets from 11.0 to 12.0. This basically enforces that the extension can be installed on Visual Studio 2013 version of Visual Studio.                         - Update the Dependencies from Visual Studio MPF 11.0 to Visual Studio MPF 12.0              9. Rebuild the solution and open up the bin folder for the Package project and look for the file *.vsix file [Microsoft Visual Studio Extension].         - This is basically the installer for your extension.                 - Double click the installer to launch the installer wizard. Viola! You can see the package installation wizard opens up and gives you the option to install the extension for Visual Studio 2013.                    - Click Install to Continue                    - Note – If you run into the exception “23/06/2013 10:42:18 - Install Error : Microsoft.VisualStudio.ExtensionManager.InstallByMsiException: The InstalledByMSI element in extension Avanade Extensions cannot be 'true' when installing an extension through the Extensions and Updates Installer.  The element can only be 'true' when an MSI lays down the extension manifest file.” Ensure you have the option “This VSIX is installed by Windows Installer” unchecked in the Install Targets tab.        10. Verifying that the extension has installed correctly.           - Open Extension Manager and verify that the installed extension shows up in the extension manager “list of installed VSIX”.                      11. First Look at the updated Extension                         - The links have now been moved to the context menu, so to see the navigation links, you’ll have to right click on the icon and select the option from the context menu.                                        Note – The Avanade Extension being used in the demo has been developed by Utkarsh and Tarun. The Software Inventory Extension for Visual Studio 2012…  allows you to see the list of Software installed on the hosted build server right from with in Visual Studio,  the extension also allows you to export this list to excel. More details on how this has been implemented can be found here.   I hope you found this useful. In case you have any questions or feedback, feel free to reach out on Visual Studio extensibility MSDN forums or via Microsoft Visual Studio feedback forum. Thank you for taking the time out and reading this blog post. If you enjoyed the post, remember to subscribe to http://feeds.feedburner.com/TarunArora. Stay tuned!

• What is the difference in WCF when using KnownType and ServiceKnownType?

  - by Paul Speranza

  I have a service that returns an array of animal but the list can contain cats, dogs, etc, which all extend animal. I know I need to use either the KnownType or ServiceKnownType attribute, and on the entity class or the service class, respectively. What is the difference between the 2 attributes? I prefer the ServiceKnownType because it is applied on the service, exactly where it is needed and called for, as opposed to KnownType which is applied on my entity. To me applying it on the entity class means knowing too far ahead how my entity class is being used. For now I have it on my entity and it works like a charm, but I am looking for guidance here as to best practices and usefullness. Thanks, Paul Speranza

• How much overhead does a msg_send call incur?

  - by pxl

  I'm attempting to piece together and run a list of tasks put together by a user. These task lists can be hundreds or thousand of items long. From what I know, the easiest and most obvious way would be to build an array and then iterate through them: NSArray *arrayOfTasks = .... init and fill with thousands of tasks for (id *eachTask in arrayOfTasks) { if ( eachTask && [eachTask respondsToSelector:@selector(execute)] ) [eachTask execute]; } For a desktop, this may be no problem, but for an iphone or ipad, this may be a problem. Is this a good way to go about it, or is there a faster way to accomplish the same thing? The reason why I'm asking about how much overhead a msg_send occurs is that I could also do a straight C implementation as well. For example, I could put together a linked list and use a block to handle the next task. Will I gain anything from that or is it really more trouble than its worth?

• Getting multiple checkboxes from FormCollection element

  - by FreshCode

  Given multiple HTML checkboxes: <input type="checkbox" name="catIDs" value="1" /> <input type="checkbox" name="catIDs" value="2" /> ... <input type="checkbox" name="catIDs" value="100" /> How do I retrive an array of integers from a FormCollection in an action: public ActionResult Edit(FormCollection form) { int [] catIDs = (IEnumerable<int>)form["catIDs"]; // ??? // alternatively: foreach (int catID in form["catIDs"] as *SOME CAST*) { // ... } return View(); } Note: I read the related questions and I don't want to change my action parameters, eg. Edit(int [] catIDs).

• Objective-C iPhone - NSMutableArray addobject becomes immediately out of scope.

  - by Robert

  ok. I have a really odd and mind boggling problem. I have two class files, both of which are NSObject inheritors. The series of code is as follows CustomClass *obj; obj = [[CustomClass alloc] init]; [myArray addObject:obj]; <--------Immediately after this line if I hover over the array it shows it as having 1 object that is out of scope. If I hover over both objects they both have what look to be initialized memory locations so I really have no idea what is going on here. Thanks in advance.

• Implementing a Patricia Trie for use as a dictionary

  - by Regis Frey

  I'm attempting to implement a Patricia Trie with the methods addWord(), isWord(), and isPrefix() as a means to store a large dictionary of words for quick retrieval (including prefix search). I've read up on the concepts but they just aren't clarifying into an implementation. I want to know (in Java or Python code) how to implement the Trie, particularly the nodes (or should I implement it recursively). I saw one person who implemented it with an array of 26 child nodes set to null/None. Is there a better strategy (such as treating the letters as bits) and how would you implement it?

• OpenGL ES Simple Undo Last Drawing

  - by Erika

  Hi Everyone, I am trying to figure out how to implement a simple "undo" of last drawing action on the iPhone screen. I draw by first preparing the frame buffer: [EAGLContext setCurrentContext:context]; glBindFramebufferOES(GL_FRAMEBUFFER_OES, viewFramebuffer); I then prepare the vertex array and draw this way: glVertexPointer(2, GL_FLOAT, 0, vertexBuffer); glDrawArrays(GL_POINTS, 0, vertexCount); glBindRenderbufferOES(GL_RENDERBUFFER_OES, viewRenderbuffer); [context presentRenderbuffer:GL_RENDERBUFFER_OES]; How do I simple undo this last action? There has to be a way to save previous state or an built-in OpenGL ES function, I would think. Thanks

• best way to save data in ipod touch/iphone objective-c

  - by Leonardo

  Hi all, I am writing a very simple application, for iphone. Unfortunately I am really a newbie. What I am trying to do is to save data at the end of a user experience. These data are really simple, only string or int, or some array. Later I want to be able to retrieve that data, therefore I also need an event id (I suppose). Could you please point out the best way, api or technology to achieve that, xml, plain text, serialization... ? many thanks Leonardo

• Handling Trailing Delimiters in HL7 Messages

  - by Thomas Canter

  Applies to: BizTalk Server 2006 with the HL7 1.3 Accelerator Outline of the problem Trailing Delimiters are empty values at the end of an object in a HL7 ER7 formatted message. Examples: Empty Field NTE|P| NTE|P|| Empty component ORC|1|725^ Empty Subcomponent ORC|1|||||27& Empty repeat OBR|1||||||||027~ Trailing delimiters indicate the following object exists and is empty, which is quite different from null, null is an explicit value indicated by a pair of double quotes -> "". The BizTalk HL7 Accelerator by default does not allow trailing delimiters. There are three methods to allow trailing delimiters. NOTE: All Schemas always allow trailing delimiters in the MSH Segment Using party identifiers MSH3.1 – Receive/inbound processing, using this value as a party allows you to configure the system to allow inbound trailing delimiters. MSH5.1 – Send/outbound processing, using this value as a party allows you to configure the system to allow outbound trailing delimiters. Generally, if you allow inbound trailing delimiters, unless you are willing to programmatically remove all trailing delimiters, then you need to configure the send to allow trailing delimiters. Add the appropriate parties to the BizTalk Parties list from these two fields in your message stream. Open the BizTalk HL7 Configuration tool and for each party check the "Allow trailing delimiters (separators)" check box on the Validation tab. Disadvantage – Each MSH3.1 and MSH5.1 value must be represented in the parties list and configured. Advantage – granular control over system behavior for each inbound/outbound system. Using instance properties of a pipeline used in a send port or receive location. Open the BizTalk Server Administration console locate the send port or receive location that contains the BTAHL72XReceivePipeline or BTAHL72XSendPipeline pipeline. Open the properties To the right of the pipeline selected locate the […] ellipses button In the property list, locate the "TrailingDelimiterAllowed" property and set it to True. Advantage – All messages through a particular Send Port or Receive Location will allow trailing delimiters. Disadvantage – Must configure each Send Port or Receive Location. No granular control over which remote parties will send or receive messages with trailing delimiters. Using a custom pipeline that uses a pre-configured BTA HL7 Pipeline component. Use Visual Studio to construct a custom receive and send pipeline using the appropriate assembler or dissasembler. Set the component property to "TrailingDelimitersAllowed" to True Compile and deploy the custom pipeline Use the custom pipeline instead of the standard pipeline for all HL7 message processing Advantage – All messages using the custom pipeline will automatically allow trailing delimiters. Disadvantage – Requires custom coding and development to create and deploy the custom pipeline. No granular control over which remote parties will send or receive messages with trailing delimiters. What does a Trailing Delimiter do to the XML Schema? Allowing trailing delimiters does not have the impact often expected in the actual XML Schema.The Schema reproduces the message with no data loss.Thus, the message when represented in XML must contain the extra fields, in order to reproduce the outbound message.Thus, a trialing delimiter results in an empty XML field.Trailing Delmiters are not stripped from the inbound message. Example:<PID_21>44172</PID_21><PID_21>9257</PID_21> -> the original maximum number of repeats<PID_21></PID_21> -> The empty repeated field Allowing trailing delimiters not remove the trailing delimiters from the message, it simply suppresses the check that will cause the message to fail parse with trailing delimiters. When can you not fix the problem by enabling trailing delimiters Each object in a message must have a location in the target BTAHL7 schema for its content to reside.If you have more objects in the message than are contained at that location, then enabling trailing delimiters will not resolve the problem. The schema must be extended to accommodate the empty message content.Examples: Extra Field NTE|P||||Only 4 fields in NTE Segment, the 4th field exists, but is empty. Extra component PID|1|1523|47^^^^^^^Only 5 components in a CX data type, the 5th component exists, but is empty Extra subcomponent ORC|1|||||27&&Only 2 subcomponents in a CQ data type, the 3rd subcomponent is empty, but exists. Extra Repeat PID|1||||||||||||||||||||4419~5217~Only 2 repeats allowed for the field "Mother's identifier", the repeat is empty, but exists. In each of these cases, you must locate the failing object and extend the type to allow an additional object of that type. FieldAdd a field of ST to the end of the segment with a suitable name in the segments_nnn.xsd Component Create a new Custom CX data type (i.e. CX_XtraComp) in the datatypes_nnn.xsd and add a new component to the custom CX data type. Update the field in the segments_nnn.xsd file to use the custom data type instead of the standard datatype. Subcomponent Create a new Custom CQ data type that accepts an additional TS value at the end of the data type. Create a custom TQ data type that uses the new custom CQ data type as the first subcomponent. Modify the ORC segment to use the new CQ data type at ORC.7 instead of the standard CQ data type. RepeatModify the Field definition for PID.21 in the segments_nnn.xsd to allow more repeats in the field.

  I have a curl class, called Curl. Let's presume i have this code: $url = 'http://www.google.com' $fields = array('q'=>'search term'); //maybe some other arguments. but let's keep it simple. $curl = new Curl(); $page = $curl->post($url,$fields); $page will have some images wich curl doesn't load them by default. I need to know how i can save a specific image without using curl. Once I use $page = $curl-post(..) I need to know how I can have that image saved without using another $curl-post(_image_location_) to get that file. The reason why need this is to save a captcha image from a form. I need to access the form and get that specific image that's being loaded. If i try to access the URL of the image, it will be a different captcha image.
