• VS2010 Web Deploy: how to remove absolute paths and automate setAcl?

  - by Julien Lebosquain

  The integrated Web Deployment in Visual Studio 2010 is pretty nice. It can create a package ready to be deployed using MSDeploy on a target IIS machine. Problem is, this package will be redistributed to a client that will install it himself using the "Import Application" from IIS when MSDeploy is installed. The default package created always include the full path from the development machine, "D:\Dev\XXX\obj\Debug\Package\PackageTmp" in the source manifest file. It doesn't prevent installation of course since it was designed this way, but it looks ugly in the import dialog and has no meaning to the client. Worse he will wonder what are those paths and it looks quite confusing. By customizing the .csproj file (by adding MSBuild properties used by the package creation task), I managed to add additional parameters to the package. However, I spent most of the afternoon in the 2600 lines long Web.Publishing.targets trying to understand what parameter influenced the "development path" behavior, in vain. I also tried to use the setAcl to customize security on a given folder after deployment, but I only managed to do this with MSBuild by using a relative path... it shouldn't matter if I resolve the first problem though. I could modify the generated archive after its creation but I would prefer if everything was automatized using MSBuild. Does anyone know how to do that?

• Ant: use include and exclude together

  - by Ken

  OK, this seems like it should be really simple. I'm using Apache Ant 1.8, and I have a target which does: <delete file="output/program.tar.bz2"/> <tar basedir="input" destfile="output/program.tar.bz2" compression="bzip2"> <tarfileset dir="input"> <include name="goodfolder1/**"/> <include name="goodfolder2/**"/> <exclude name="**/badfile"/> <exclude name="**/*.badext"/> </tarfileset> </tar> I want it to make a .tar.bz2 of input/goodfolder1 and input/goodfolder2, excluding files named "badfile", and excluding files with extension ".badext". It's giving me a .tar.bz2, but it's including badfile and *.badext -- the excludes seem to be ignored. The order of include/exclude doesn't seem to make a difference. I tried wrapping the includes/excludes in a (the docs say it's implicit?), but it made no difference. I'm sure there's something simple I'm missing, since the manual has a very similar example, though in a somewhat different context. EDIT: It looks like it could be related to the dir="input" attribute: it's adding everything in "input", and then adding everything in the tarfileset to that. Files I want appear twice in the program.tar.bz2, but files that are excluded only appear once. But dir is mandatory, and I don't see how this is different from the examples in the manual.

• Something about Stream

  - by sforester

  I've been working on something that make use of streams and I found myself not clear about some stream concepts( you can also view another question posted by me at http://stackoverflow.com/questions/2933923/about-redirected-stdout-in-system-diagnostics-process ). 1.how do you indicate that you have finished writing a stream, writing something like a EOF? 2.follow the previous question, if I have written a EOF(or something like that) to a stream but didn't close the stream, then I want to write something else to the same stream, can I just start writing to it and no more set up required? 3.if a procedure tries to read a stream(like the stdin ) that no one has written anything to it, the reading procedure will be blocked,finally some data arrives and the procedure will just read till the writing is done,which is indicated by getting a return of 0 count of bytes read rather than being blocked, and now if the procedure issues another read to the same stream, it will still get a 0 count and return immediately while I was expecting it will be blocked since no one is writing to the stream now. So does the stream holds different states when the stream is opened but no one has written to it yet and when someone has finished a writing session? I'm using Windows the .net framework if there will by any thing platform specific. Thanks a lot!

• updating multiple nodes in xml with xquery and xdmp:node-replace

  - by morja

  Hi all, I wnat to update an XML document in my xml database (Marklogic). I have xml as input and want to replace each node that exists in the target xml. If a node does not exist it would be great if it gets added, but thats maybe another task. My XML in the database: <user> <username>username</username> <firstname>firstname</firstname> <lastname>lastname</lastname> <email>[email protected]</email> <comment>comment</comment> </user> The value of $user_xml: <user> <firstname>new firstname</firstname> <lastname>new lastname</lastname> </user> My function so far: declare function update-user ( $username as xs:string, $user_xml as node()) as empty-sequence() { let $uri := user-uri($username) return for $node in $user_xml/user return xdmp:node-replace(fn:doc($uri)/user/fn:node-name($node), $node) }; First of all I cannot iterate over $user_xml/user. If I try to iterate over $user_xml I get "arg1 is not of type node()" exception. But maybe its the wrong approach anyway? Does anybody maybe have sample code how to do this?

• upgrading to spring 3.0 problem with interceptorNames

  - by mkoryak

  I am trying to upgrade to Spring 3.0 and i have the following issues: Finding the dependencies. People recommend using maven, but id rather not try to learn how to use maven/install it if the jars are available somewhere for download. The following bean declaration is now longer valid but i dont know how to fix it: <bean id="service" class="org.springframework.aop.framework.ProxyFactoryBean"> <property name="proxyInterfaces" value="com.service.SomeService" /> <property name="target"> <bean class="com.service.SomeServiceImpl"> </bean> </property> <property name="interceptorNames"> <list> <value>hibernateInterceptor</value> </list> </property> </bean> The complaint is that <property name="interceptorNames"> is no longer supported and should be done some other way

• Create a model that switches between two different states using Temporal Logic?

  - by NLed

  Im trying to design a model that can manage different requests for different water sources. Platform : MAC OSX, using latest Python with TuLip module installed. For example, Definitions : Two water sources : w1 and w2 3 different requests : r1,r2,and r3 - Specifications : Water 1 (w1) is preferred, but w2 will be used if w1 unavailable. Water 2 is only used if w1 is depleted. r1 has the maximum priority. If all entities request simultaneously, r1's supply must not fall below 50%. - The water sources are not discrete but rather continuous, this will increase the difficulty of creating the model. I can do a crude discretization for the water levels but I prefer finding a model for the continuous state first. So how do I start doing that ? Some of my thoughts : Create a matrix W where w1,w2 ? W Create a matrix R where r1,r2,r3 ? R or leave all variables singular without putting them in a matrix I'm not an expert in coding so that's why I need help. Not sure what is the best way to start tackling this problem. I am only interested in the model, or a code sample of how can this be put together. edit Now imagine I do a crude discretization of the water sources to have w1=[0...4] and w2=[0...4] for 0, 25, 50, 75,100 percent respectively. == means implies Usage of water sources : if w1[0]==w2[4] -- meaning if water source 1 has 0%, then use 100% of water source 2 etc if w1[1]==w2[3] if w1[2]==w2[2] if w1[3]==w2[1] if w1[4]==w2[0] r1=r2=r3=[0,1] -- 0 means request OFF and 1 means request ON Now what model can be designed that will give each request 100% water depending on the values of w1 and w2 (w1 and w2 values are uncontrollable so cannot define specific value, but 0...4 is used for simplicity )

• [hibernate - jpa] @OneToOne annotoation problem (i think...)

  - by blow

  Hi all, im new in hibernate and JPA and i have some problems with annotations. My target is to create this table in db (PERSON_TABLE with personal-details) ID ADDRESS NAME SURNAME MUNICIPALITY_ID First of all, i have a MUNICIPALITY table in db containing all municipality of my country. I mapped this table in this ENTITY: @Entity public class Municipality implements Serializable { @Id @GeneratedValue(strategy=GenerationType.IDENTITY) private Long id; private String country; private String province; private String name; @Column(name="cod_catasto") private String codCatastale; private String cap; public Municipality() { } ... Then i make an EMBEDDABLE class Address containing fields that realize a simple address... @Embeddable public class Address implements Serializable { @OneToOne(cascade=CascadeType.ALL) @JoinColumn(name="id_municipality") private Municipality municipality; @Column(length=45) private String address; public Address() { } ... Finally i embedded this class into Person ENTITY @Entity public class Person implements Serializable { @Id @GeneratedValue(strategy=GenerationType.IDENTITY) private Long id; private String name; private String surname; @Embedded private Address address; public Person() { } ... All works good when i have to save a new Person record, in fact hibernate creates a PERSON_TABLE as i want, but if i try to retrieve a Person record i have an exception. HQL is simply "from Person" The excpetion is (Entities is the package containing all classes above-mentioned): org.hibernate.AnnotationException: @OneToOne or @ManyToOne on Entities.Person.address.municipality references an unknown entity: Entities.Municipality Is the @OneToOne annotation the problem? Thanks.

• how to elegantly duplicate a graph (neural network)

  - by macias

  I have a graph (network) which consists of layers, which contains nodes (neurons). I would like to write a procedure to duplicate entire graph in most elegant way possible -- i.e. with minimal or no overhead added to the structure of the node or layer. Or yet in other words -- the procedure could be complex, but the complexity should not "leak" to structures. They should be no complex just because they are copyable. I wrote the code in C#, so far it looks like this: neuron has additional field -- copy_of which is pointer the the neuron which base copied from, this is my additional overhead neuron has parameterless method Clone() neuron has method Reconnect() -- which exchanges connection from "source" neuron (parameter) to "target" neuron (parameter) layer has parameterless method Clone() -- it simply call Clone() for all neurons network has parameterless method Clone() -- it calls Clone() for every layer and then it iterates over all neurons and creates mappings neuron=copy_of and then calls Reconnect to exchange all the "wiring" I hope my approach is clear. The question is -- is there more elegant method, I particularly don't like keeping extra pointer in neuron class just in case of being copied! I would like to gather the data in one point (network's Clone) and then dispose it completely (Clone method cannot have an argument though).

• Boost::Asio - Remove the "null"-character in the end of tcp packets.

  - by shump

  I'm trying to make a simple msn client mostly for fun but also for educational purposes. And I started to try some tcp package sending and receiving using Boost Asio as I want cross-platform support. I have managed to send a "VER"-command and receive it's response. However after I send the following "CVR"-command, Asio casts an "End of file"-error. After some further researching I found by packet sniffing that my tcp packets to the messenger server got an extra "null"-character (Ascii code: 00) at the end of the message. This means that my VER-command gets an extra character in the end which I don't think the messenger server like and therefore shuts down the connection when I try to read the CVR response. This is how my package looks when sniffing it, (it's Payload): (Hex:) 56 45 52 20 31 20 4d 53 4e 50 31 35 20 43 56 52 30 0a 0a 00 (Char:) VER 1 MSNP15 CVR 0... and this is how Adium(chat client for OS X)'s package looks: (Hex:) 56 45 52 20 31 20 4d 53 4e 50 31 35 20 43 56 52 30 0d 0a (Char:) VER 1 MSNP15 CVR 0.. So my question is if there is any way to remove the null-character in the end of each package, of if I've misunderstood something and used Asio in a wrong way. My write function (slightly edited) looks lite this: int sendVERMessage() { boost::system::error_code ignored_error; char sendBuf[] = "VER 1 MSNP15 CVR0\r\n"; boost::asio::write(socket, boost::asio::buffer(sendBuf), boost::asio::transfer_all(), ignored_error); if(ignored_error) { cout << "Failed to send to host!" << endl; return 1; } cout << "VER message sent!" << endl; return 0; } And here's the main documentation on the msn protocol I'm using. Hope I've been clear enough.

• Indices instead of pointers in STL containers?

  - by zvrba

  Due to specific requirements [*], I need a singly-linked list implementation that uses integer indices instead of pointers to link nodes. The indices are always interpreted with respect to a vector containing the list nodes. I thought I might achieve this by defining my own allocator, but looking into the gcc's implementation of , they explicitly use pointers for the link fields in the list nodes (i.e., they do not use the pointer type provided by the allocator): struct _List_node_base { _List_node_base* _M_next; ///< Self-explanatory _List_node_base* _M_prev; ///< Self-explanatory ... } (For this purpose, the allocator interface is also deficient in that it does not define a dereference function; "dereferencing" an integer index always needs a pointer to the underlying storage.) Do you know a library of STL-like data structures (i am mostly in need of singly- and doubly-linked list) that use indices (wrt. a base vector) instead of pointers to link nodes? [*] Saving space: the lists will contain many 32-bit integers. With two pointers per node (STL list is doubly-linked), the overhead is 200%, or 400% on 64-bit platform, not counting the overhead of the default allocator.

• Get subdomain of XML page from XSL

  - by fudgey

  I am working with a guild hosting site that provides an XML/XSL transformation widget where all I need to do is enter the URL for the XML and XSL and it does the rest. I have written an XSL transform to display a World of Warcraft armory page: Here is an example XML page (view source to see it) of the group I'm trying to help now. So, the user is entering their own XML page url (which has an eu subdomain in this case, but it is not within the XML itself). So when I make links to the character url, I need to add the entire url <a target="_blank" href="http://eu.wowarmory.com/character-sheet.xml?{@url}"> <xsl:value-of select="@name"/> </a> But I can't just set the domain to eu since there are multiple regions. Here are the possibilities: us = www, europe = eu, korea = kr, china = cn and taiwan = tw. Here is a snippet of the XML which shows the url parameters: <character achPoints="4275" classId="3" genderId="0" level="80" name="Virtex" raceId="4" rank="2" url="r=Drek%27Thar&amp;cn=Virtex"/> I guess I could just have the user add a small bit of HTML with their region in another part of their page, something like <div id="region">eu</div>, but I'm trying to make this work without any extra coding on their part. Edit: Ok, my question explicitly stated: How do I get the URL subdomain using XSL?

• [Database] How to model this one-to-one relation?

  - by pbean

  I have several entities which respresent different types of users who need to be able to log in to a particular system. Additionally, they have different types of information associated with them. For example: a "general user", which has an e-mail address and "admin user", which has a workstation number (note that this a hypothetical case). Both entities also share common properties like first name, surname, address and telephone number. Finally, they naturally need to have a (unique) user name and a password to log in. In the application, the user just has to fill in his user name and password, and the functionality of the application changes slightly according to the type of the user. You can imagine that the username needs to be unique for this work. How should I model this effectively? I can't just create two tables, because then I can't force a unique constaint on the user name. I also can't put them all in just one table, because they have different types of specific information associated to them. I think I might need 3 seperate tables, one for "users" (with user name and password), one for the "general users" and another one for the "admin users", but how would the relations between these work? Or is there another solution? (By the way, the target DBMS is MySQL, so I don't think generalization is supported in the database system itself).

• N-gram split function for string similarity comparison

  - by Michael

  As part of excersise to better understand F# which I am currently learning , I wrote function to split given string into n-grams. 1) I would like to receive feedback about my function : can this be written simpler or in more efficient way? 2) My overall goal is to write function that returns string similarity (on 0.0 .. 1.0 scale) based on n-gram similarity; Does this approach works well for short strings comparisons , or can this method reliably be used to compare large strings (like articles for example). 3) I am aware of the fact that n-gram comparisons ignore context of two strings. What method would you suggest to accomplish my goal? //s:string - target string to split into n-grams //n:int - n-gram size to split string into let ngram_split (s:string, n:int) = let ngram_count = s.Length - (s.Length % n) let ngram_list = List.init ngram_count (fun i -> if( i + n >= s.Length ) then s.Substring(i,s.Length - i) + String.init ((i + n) - s.Length) (fun i -> "#") else s.Substring(i,n) ) let ngram_array_unique = ngram_list |> Seq.ofList |> Seq.distinct |> Array.ofSeq //produce tuples of ngrams (ngram string,how much occurrences in original string) Seq.init ngram_array_unique.Length (fun i -> (ngram_array_unique.[i], ngram_list |> List.filter(fun item -> item = ngram_array_unique.[i]) |> List.length) )

• Spring 3 MVC validation BindingResult doesn't contain any errors

  - by Travelsized

  I'm attempting to get a Spring 3.0.2 WebMVC project running with the new annotated validation support. I have a Hibernate entity annotated like this: @Entity @Table(name = "client") public class Client implements Serializable { private static final long serialVersionUID = 1L; @Id @Basic(optional = false) @Column(name = "clientId", nullable = false) @NotEmpty private Integer clientId; @Basic(optional = false) @Column(name = "firstname", nullable = false, length = 45) @NotEmpty @Size(min=2, max=45) private String firstname; ... more fields, getters and setters } I've turned on mvc annotation support in my applicationContext.xml file: <mvc:annotation-driven /> And I have a method in my controller that responds to a form submission: @RequestMapping(value="/addClient.htm") public String addClient(@ModelAttribute("client") @Valid Client client, BindingResult result) { if(result.hasErrors()) { return "addClient"; } service.storeClient(client); return "clientResult"; } When my app loads in the server, I can see in the server log file that it loads a validator: 15 [http-8084-2] INFO org.hibernate.validator.util.Version - Hibernate Validator 4.0.2.GA The problem I'm having is that the validator doesn't seem to kick in. I turned on the debugger, and when I get into the controller method, the BindingResult contains 0 errors after I submit an empty form. (The BindingResult does show that it contains the Client object as a target.) It then proceeds to insert a record without an Id and throws an exception. If I fill out an Id but leave the name blank, it creates a record with the Id and empty fields. What steps am I missing to get the validation working?

• Intent provided by Cursor is not fired correctly (LiveFolders)

  - by Felix

  In my desperation with trying to get LiveFolders working, I have tried the following in my LiveFolder ContentProvider: public Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder) { MatrixCursor mc = new MatrixCursor(new String[] { LiveFolders._ID, LiveFolders.NAME, LiveFolders.INTENT } ); Intent i = null; for (int j=0; j < 5; j++) { i = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com/")); mc.addRow(new Object[] { j, "hello", i} ); } return mc; } Which, in all normalness, should launch the Browser and display the Google homepage when clicking on an item in the LiveFolder. But it doesn't. It gives a Application is not installed on your phone error. No, I'm not defining a base intent for my LiveFolder. logcat says: I/ActivityManager( 74): Starting activity: Intent { act=android.intent.action.VIEW dat=Intent { act=android.intent.action.VIEW dat=http://www.google.com/ } flg=0x10000000 } It seems it embeds the Intent I give it in the data section of the actually fired Intent. Why is it doing this? I'm really starting to believe it's a platform bug.

• Endianness and C API's: Specifically OpenSSL.

  - by Hassan Syed

  I have an algorithm that uses the following OpenSSL calls: HMAC_update() / HMAC_final() // ripe160 EVP_CipherUpdate() / EVP_CipherFinal() // cbc_blowfish These algorithm take a unsigned char * into the "plain text". My input data is comes from a C++ std::string::c_str() which originate from a protocol buffer object as a encoded UTF-8 string. UTF-8 strings are meant to be endian neutrial. However I'm a bit paranoid about how OpenSSL may perform operations on the data. My understanding is that encryption algorithms work on 8-bit blocks of data, and if a unsigned char * is used for pointer arithmetic when the operations are performed the algorithms should be endian neutral and I do not need to worry about anything. My uncertainty is compounded by the fact that I am working on a little-endian machine and have never done any real cross-architecture programming. My beliefs/reasoning are/is based on the following two properties std::string (not wstring) internally uses a 8-bit ptr and a the resulting c_str() ptr will itterate the same way regardless of the CPU architecture. Encryption algorithms are either by design, or by implementation, endian neutral. I know the best way to get a definitive answer is to use QEMU and do some cross-platform unit tests (which I plan to do). My question is a request for comments on my reasoning, and perhaps will assist other programmers when faced with similar problems.

• Chrome targeted CSS

  - by Chris

  I have some CSS code that hides the cursor on a web page (it is a client facing static screen with no interaction). The code I use to do this is below: *, html { cursor: url('/web/resources/graphics/blank.cur'), pointer; } Blank.cur is a totally blank cursor file. This code works perfectly well in all browsers when I host the web files on my local server but when I upload to a Windows CE webserver (our production unit) the cursor represents itself as a black box. Odd. After some testing it seems that chrome only has a problem with totally blank cursor files when served from WinCE web server, so I created a blank cursor with one pixel as white, specifically for chrome. How do I then target this CSS rule to chrome specifically? i.e. *, html { cursor: url('/web/resources/graphics/blank.cur'), pointer; } <!--[if CHROME]> *, html { cursor: url('/web/resources/graphics/blankChrome.cur'), pointer; } <![endif]-->

• how can i check ID of a clicked element js

  - by necker

  how can i check if an ID of a clicked element is lets say 'target'. what i am trying to do is actually show and hide comment form on clicking in the text field and hide it when the user clicks out of the form. the problem is that if the user clicks Submit button the form hides and nothing is sent over. so i'll have to check if the submit buttons id matches the clicked element and not hide it in this case. i am using ruby on rails remote_form_for and onblur and onfocus events now. this is my bigger form that i am showing. <div id="bigArea" style="display:none"> <% remote_form_for @horses do |f|%> <%= f.text_area :description, {:onBlur=>"{$(bigArea').hide();$('smallField').show();}"} %> <%= f.submit "Submit"%> <% end %> </div> and this is the smaller form field that hides everytime you click in it. <div id="smallField"> <%= text_field_tag 'sth',"Click to comment, {:onFocus=>"$('bigArea').show();$('smallField').hide();"} %> </div> My question is how can i disallow the form to hide when a user clicks submit button? i suppose i should check which element's id has been clicked. and if it's submit button's ID i should not hide the form. Or maybe there is some other way to do all this? i would greatly appreciate any answers!

• How can one convince a team to use a new technology (LinQ, MVC, etc )?

  - by Atomiton

  Obviously, it's easier to do with some developers, but I'm sure many of us are on teams that prefer the status quo. You know the type. You see some benefit in a piece of new technology and they prefer the tried and true methods. Try, for example, DBA/C# programmer the advantages of using LinQ ( not necessarily LinQ to SQL, just LinQ in general ). For example, When a project requirement is to be cross-platform... instead of thinking about how one can run Windows on a Mac through a VM Machine, introducing the idea of using relatively new Silverlight or creating it in Java ( as an option to look into ). I know most people don't like to be out of their comfort level, so it takes a bit of convincing, and not ALL new technology makes business sense... but how have you convinced your team to look at a new technology? What technologies have you successfully introduced to your workplace? What technologies do you think are hardest to introduce? ( I'm thinking paradigm-shifting ones, like MVC from WebForms... or new languages ) What strategies do you employ to make these new technologies appealing?

• How should rules for Aggregate Roots be enforced?

  - by MylesRip

  While searching the web, I came across a list of rules from Eric Evans' book that should be enforced for aggregates: The root Entity has global identity and is ultimately responsible for checking invariants Root Entities have global identity. Entities inside the boundary have local identity, unique only within the Aggregate. Nothing outside the Aggregate boundary can hold a reference to anything inside, except to the root Entity. The root Entity can hand references to the internal Entities to other objects, but they can only use them transiently (within a single method or block). Only Aggregate Roots can be obtained directly with database queries. Everything else must be done through traversal. Objects within the Aggregate can hold references to other Aggregate roots. A delete operation must remove everything within the Aggregate boundary all at once When a change to any object within the Aggregate boundary is committed, all invariants of the whole Aggregate must be satisfied. This all seems fine in theory, but I don't see how these rules would be enforced in the real world. Take rule 3 for example. Once the root entity has given an exteral object a reference to an internal entity, what's to keep that external object from holding on to the reference beyond the single method or block? (If the enforcement of this is platform-specific, I would be interested in knowing how this would be enforced within a C#/.NET/NHibernate environment.)

• Warning: cast increases required alignment

  I'm recently working on this platform for which a legacy codebase issues a large number of "cast increases required alignment to N" warnings, where N is the size of the target of the cast. struct Message { int32_t id; int32_t type; int8_t data[16]; }; int32_t GetMessageInt(const Message& m) { return *reinterpret_cast<int32_t*>(&data[0]); } Hopefully it's obvious that a "real" implementation would be a bit more complex, but the basic point is that I've got data coming from somewhere, I know that it's aligned (because I need the id and type to be aligned), and yet I get the message that the cast is increasing the alignment, in the example case, to 4. Now I know that I can suppress the warning with an argument to the compiler, and I know that I can cast the bit inside the parentheses to void* first, but I don't really want to go through every bit of code that needs this sort of manipulation (there's a lot because we load a lot of data off of disk, and that data comes in as char buffers so that we can easily pointer-advance), but can anyone give me any other thoughts on this problem? I mean, to me it seems like such an important and common option that you wouldn't want to warn, and if there is actually the possibility of doing it wrong then suppressing the warning isn't going to help. Finally, can't the compiler know as I do how the object in question is actually aligned in the structure, so it should be able to not worry about the alignment on that particular object unless it got bumped a byte or two?

• jQuery ajax post of jpg image to .net webservice. Image results corrupted

  - by sosergio

  I have a phonegap jquery app that opens the camera and take a picture. I then POST this picture to a .net webservice, wich I've coded. I can't use phonegap FileTransfer because such isn't supported by Bada os, wich is a requirement. I believe I've successfully loaded the image from phonegap FileSystem API, I've attached it into an .ajax type:post, I've even received it from .net side, but when .net save the image into the server, the image results corrupted. It seems to me that two sides of the communication have different data type. Has anyone experience in this? Any help will be appreciated. This is my code: //PHONEGAP CAMERA ACCESS (summed up) navigator.camera.getPicture(onGetPictureSuccess, onGetPictureFail, { quality: 50, destinationType:Camera.DestinationType.FILE_URI }); window.resolveLocalFileSystemURI(imageURI, onResolveFileSystemURISuccess, onResolveFileSystemURIError); fileEntry.file(gotFileSuccess, gotFileError); new FileReader().readAsDataURL(file); //UPLOAD FILE function onDataReadSuccess(evt) { var image_data = evt.target.result; var filename = unique_id(); var filext = "jpg"; $.ajax({ type : 'POST', url : SERVICE_BASE_URL+"/fotos/"+filename+"?ext="+filext, cache: false, timeout: 100000, processData: false, data: image_data, contentType: 'image/jpeg', success : function(data) { console.log("Data Uploaded with success. Message: "+ data); $.mobile.hidePageLoadingMsg(); $.mobile.changePage("ok.html"); } }); } On my .net Web Service this is the method that gets invoked: public string FotoSave(string filename, string extension, Stream fileContent) { string filePath = HttpContext.Current.Server.MapPath("~/foto_data/") + "\\" + filename; FileStream writeStream = new FileStream(filePath, FileMode.OpenOrCreate, FileAccess.Write); int Length = 256; Byte[] buffer = new Byte[Length]; int bytesRead = readStream.Read(buffer, 0, Length); // write the required bytes while (bytesRead > 0) { writeStream.Write(buffer, 0, bytesRead); bytesRead = readStream.Read(buffer, 0, Length); } readStream.Close(); writeStream.Close(); }
