• [Smalltalk] Store List of Instruction

  - by Luciano Lorenti

  Hi all, I have a design Problem. i have a Drawer class wich invokes a serie of methods of a kind-of-brush class and i have a predefined shapes which i want to draw. Each shape uses a list of instance methods from the drawer. I can have more than 1 brush object. I want to add custom shapes on runtime in the drawer instance, especifying the list of methods of the new shape. i've created a class method for every predefined shape that returns a BlockClosure with the instruccions. Obviously i have to give to each BlockClosure the brush object as parameter. I imagine a collection with all the BlockClosures in each instance of the Drawer Class. Maybe i can inherit a SequenceableCollection and make a instruccion collection. Each element of the collection it's a instruction and i give the brush object when i instance this new collection. I really don't know the best way to store these steps. (Maybe a shared variable?)

• How to map different UI views in a RESTful web application?

  - by MicE

  Hello, I'm designing a web application, which will support both standard UIs (accessed via browsers) and a RESTful API (an XML/JSON-based web service). User agents will be able to differentiate between these by using different values in the Accept HTTP header. The RESTful API will use the following URI structure (example for an "article" resource): GET /article/ - gets a list of articles POST /article/ - adds a new article PUT /article/{id} - updates an existing article based on {id} DELETE /article/{id} - deletes an existing article based on {id} The UI part of the application will however need to support multiple views, for example: a standard resource view a view for submitting a new resource a view for editing an existing resource a view for deleting an existing resource (i.e. display delete confirmation) Note that the latter three views are still accessed via GET, even though they are processed via overloaded POST. Possible solution: Introduce additional parameters (keywords) into URIs which would identify individual views - i.e. on top of the above, the application would support the following URIs (but only for Content-Type: text/html): GET /article/add - displays a form for adding a new article (fetched via GET, processed via POST) GET /article/123 - displays article 123 in "view" mode (fetched via GET) GET /article/123/edit - displays article 123 in "edit" mode (fetched via GET, processed via PUT overloaded as POST) GET /article/123/delete - displays "delete" confirmation for article 123 (fetched via GET, processed via DELETE overloaded as POST) A better implementation of the above might be to put the add/edit/delete keywords into a GET parameter - since they do not change the resource we're working with, it might be better to keep the base URI same for all of them. My question is: How would you map the above URI structure to UIs served to the regular user, considering that there can be several views per each resource, please? Do you agree with the possible solution detailed above, or would you recommend a different approach based on your experience? NB: we've already implemented an application which consists of a standalone RESTful API and a standalone web application. I'm currently looking into options for future projects where these two would be merged together (i.e. in order to reduce overhead). Thank you, M.

• XSLT: use parameters in xls:sort attributes

  - by fireeyedboy

  How do I apply a parameter to a select and order attribute in a xsl:sort element? I'ld like to do this dynamic with PHP with something like this: $xsl = new XSLTProcessor(); $xslDoc = new DOMDocument(); $xslDoc->load( $this->_xslFilePath ); $xsl->importStyleSheet( $xslDoc ); $xsl->setParameter( '', 'sortBy', 'viewCount' ); $xsl->setParameter( '', 'order', 'descending' ); But I'ld first have to now how to get this to work.

• Java reflection

  - by heldopslippers

  Hi people. I have a question about reflection I am trying to have some kind of eval() method. So i can call for example: eval("test('woohoo')"); Now I understand the there is no eval method in java but there is reflection. I made the following code: String s = "test"; Class cl = Class.forName("Main"); Method method = cl.getMethod(s, String.class); method.invoke(null, "woohoo"); This works perfectly (of course there is a try, catch block around this code). It runs the test method. However I want to call multiple methods who all have different parameters. I don't know what parameters these are (so not only String.class). But how is this possible? how can I get the parameter types of a method ? I know of the following method: Class[] parameterTypes = method.getParameterTypes(); But that will return the parameterTypes of the method I just selected! with the following statement: Method method = cl.getMethod(s, String.class); Any help would be appreciated !

• Extension method using Reflection to Sort

  - by Xavier

  I implemented an extension "MyExtensionSortMethod" to sort collections (IEnumerate). This allows me to replace code such as 'entities.OrderBy( ... ).ThenByDescending( ...)' by 'entities.MyExtensionSortMethod()' (no parameter as well). Here is a sample of implementation: //test function function Test(IEnumerable<ClassA> entitiesA,IEnumerable<ClassB> entitiesB ) { //Sort entitiesA , based on ClassA MySort method var aSorted = entitiesA.MyExtensionSortMethod(); //Sort entitiesB , based on ClassB MySort method var bSorted = entitiesB.MyExtensionSortMethod(); } //Class A definition public classA: IMySort<classA> { .... public IEnumerable<classA> MySort(IEnumerable<classA> entities) { return entities.OrderBy( ... ).ThenBy( ...); } } public classB: IMySort<classB> { .... public IEnumerable<classB> MySort(IEnumerable<classB> entities) { return entities.OrderByDescending( ... ).ThenBy( ...).ThenBy( ... ); } } //extension method public static IEnumerable<T> MyExtensionSortMethod<T>(this IEnumerable<T> e) where T : IMySort<T>, new() { //the extension should call MySort of T Type t = typeof(T); var methodInfo = t.GetMethod("MySort"); //invoke MySort var result = methodInfo.Invoke(new T(), new object[] {e}); //Return return (IEnumerable < T >)result; } public interface IMySort<TEntity> where TEntity : class { IEnumerable<TEntity> MySort(IEnumerable<TEntity> entities); } However, it seems a bit complicated compared to what it does so I was wondering if they were another way of doing it?

• How can I add the "--watch" flag to this TextMate snippet?

  - by Jannis

  I love TextMate as my editor for all things web, and so I'd like to use a snippet to use it with style.less files to automatically take advantage of the .less way of compiling .css files on the fly using the native $ lessc {filepath} --watch as suggested in the less documentation (link) My (thanks to someone who wrote the LESS TM Bundle!) current TextMate snippet works well for writing the currently opened .less file to the .css file but I'd like to take advantage of the --watch parameter so that every change to the .less file gets automatically compiled into the .css file. This works well when using the Terminal command line for it, so I am sure it must be possible to use it in an adapted version of the current LESS Command for TextMate since that only invokes the command to compile the file. So how do I add the --watch flag to this command:? #!/usr/bin/env ruby file = STDIN.read[/lessc: ([^*]+\.less)/, 1] || ENV["TM_FILEPATH"] system("lessc \"#{file}\"") I assume it should be something like: #!/usr/bin/env ruby file = STDIN.read[/lessc: ([^*]+\.less)/, 1] || ENV["TM_FILEPATH"] system("lessc \"#{file}\" --watch") But doing so only crashes the TextMate.app. Any ideas would be much appreciated. Thanks for reading. Jannis

• CascadingDropDown taking two parameters...

  - by WeeShian

  I have a page with 3 dropdownlist, 2nd and 3rd dropdownlist are added with CascadingDropDown. 3rd dropdownlist will take parameters from 1st and 2nd dropdownlist. So, in current example for CascadingDropDown i have found from google, they are only passing one parameter to the WebService method. How can pass two parameters to the service method, so that my 3rd dropdownlist will based on the SelectedValue of 1st and 2nd dropdownlist? <WebMethod()> _ Public Function GetTeams(ByVal knownCategoryValues As String, ByVal category As String) As CascadingDropDownNameValue() Dim strConnection As String = ConfigurationManager.ConnectionStrings("nerdlinessConnection").ConnectionString Dim sqlConn As SqlConnection = New SqlConnection(strConnection) Dim strTeamQuery As String = "SELECT * FROM TEAM WHERE conf_id = @confid" Dim cmdFetchTeam As SqlCommand = New SqlCommand(strTeamQuery, sqlConn) Dim dtrTeam As SqlDataReader Dim kvTeam As StringDictionary = CascadingDropDown.ParseKnownCategoryValuesString(knownCategoryValues) Dim intConfId As Integer If Not kvTeam.ContainsKey("Conference") Or Not Int32.TryParse(kvTeam("Conference"), intConfId) Then Return Nothing End If cmdFetchTeam.Parameters.AddWithValue("@confid", intConfId) Dim myTeams As New List(Of CascadingDropDownNameValue) sqlConn.Open() dtrTeam = cmdFetchTeam.ExecuteReader While dtrTeam.Read() Dim strTeamName As String = dtrTeam("team_name").ToString Dim strTeamId As String = dtrTeam("team_id").ToString myTeams.Add(New CascadingDropDownNameValue(strTeamName, strTeamId)) End While Return myTeams.ToArray End Function This is the sample code i found! As you can see in the code, '@confid' will be passed from 2nd dropdownlist! So, hw do i modify this code to get the selected value from 1st dropdownlist as well??

• How I shoud use BIT in MS SQL 2005

  - by adopilot

  Regarding to SQL performance. I have Scalar-Valued function for checking some specific condition in base, It returns BIT value True or False, I now do not know how I should fill @BIT parameter If I write. set @bit = convert(bit,1) or set @bit = 1 or set @bit='true' Function will work anyway but I do not know which method is recommended for daily use. Another Question, I have table in my base with around 4 million records, Daily insert is about 4K records in that table. Now I want to add CONSTRAINT on that table whit scalar valued function that I mentioned already Something like this ALTER TABLE fin_stavke ADD CONSTRAINT fin_stavke_knjizenje CHECK ( dbo.fn_ado_chk_fin(id)=convert(bit,1)) Where is filed "id" primary key of table fin_stavke and dbo.fn_ado_chk_fin looks like create FUNCTION fn_ado_chk_fin ( @stavka_id int ) RETURNS bit AS BEGIN declare @bit bit if exists (select * from fin_stavke where id=@stavka_id and doc_id is null and protocol_id is null) begin set @bit=0 end else begin set @bit=1 end return @bit; END GO Will this type and method of cheeking constraint will affect badly performance on my table and SQL at all ? If there is also better way to add control on this table please let me know.

• Covariance and Contravariance inference in C# 4.0

  - by devoured elysium

  When we define our interfaces in C# 4.0, we are allowed to mark each of the generic parameters as in or out. If we try to set a generic parameter as out and that'd lead to a problem, the compiler raises an error, not allowing us to do that. Question: If the compiler has ways of inferring what are valid uses for both covariance (out) and contravariance(in), why do we have to mark interfaces as such? Wouldn't it be enough to just let us define the interfaces as we always did, and when we tried to use them in our client code, raise an error if we tried to use them in an un-safe way? Example: interface MyInterface<out T> { T abracadabra(); } //works OK interface MyInterface2<in T> { T abracadabra(); } //compiler raises an error. //This makes me think that the compiler is cappable //of understanding what situations might generate //run-time problems and then prohibits them. Also, isn't it what Java does in the same situation? From what I recall, you just do something like IMyInterface<? extends whatever> myInterface; //covariance IMyInterface<? super whatever> myInterface2; //contravariance Or am I mixing things? Thanks

• Duck type testing with C# 4 for dynamic objects.

  - by Tracker1

  I'm wanting to have a simple duck typing example in C# using dynamic objects. It would seem to me, that a dynamic object should have HasValue/HasProperty/HasMethod methods with a single string parameter for the name of the value, property, or method you are looking for before trying to run against it. I'm trying to avoid try/catch blocks, and deeper reflection if possible. It just seems to be a common practice for duck typing in dynamic languages (JS, Ruby, Python etc.) that is to test for a property/method before trying to use it, then falling back to a default, or throwing a controlled exception. The example below is basically what I want to accomplish. If the methods described above don't exist, does anyone have premade extension methods for dynamic that will do this? Example: In JavaScript I can test for a method on an object fairly easily. //JavaScript function quack(duck) { if (duck && typeof duck.quack === "function") { return duck.quack(); } return null; //nothing to return, not a duck } How would I do the same in C#? //C# 4 dynamic Quack(dynamic duck) { //how do I test that the duck is not null, //and has a quack method? //if it doesn't quack, return null }

• What is actually happening to this cancelled HTTP request?

  - by Brian Schroth

  When a user takes a particular action on a page, an AJAX call is made to save their data. Unfortunately, this call is synchronous as they need to wait to see if the data is valid before being allowed to continue. Obviously, this eliminates a lot of the benefit of using Asynchronous Javascript And XML, but that's a subject for another post. That's the design I'm working with. The request is made using the dojo.xhrPost function, with a 60s timeout parameter, and the error handler redirects to an error page. What I am finding in testing is that in Firefox, if I initiate the ajax request and then press ESC, the page hangs waiting for a response, and then eventually after exactly 90s (not 60s, the function's timeout), the error handler will kick in and redirect to the error page. I expected this to happen, but either immediately as soon as the request was cancelled, or after 60s due to the timeout value being 60s. What I don't understand is why is it 90s? What is actually happening under the hood when the user cancels their request in Firefox, and how does it differ from IE, where everything works fine exactly the same as if the request had not been cancelled? Is the 90s related to any user-configurable browser settings?

• HttpServerUtility.UrlTokenDecode fails "sometimes" (Invalid length for a Base-64 char array.)

  - by Josef

  We have an IHttpHandler for stylesheets and add a <link/> tag to the page like this: HtmlGenericControl link = new HtmlGenericControl("link"); link.Attributes.Add("rel", "stylesheet"); link.Attributes.Add("href", "stylesheet.axd?d=" + HttpServerUtility.UrlTokenEncode(token)); head.Controls.Add(link); In the stylesheet.axd handler, we UrlTokenDecode the d query string parameter like this: var token = HttpServerUtility.UrlTokenDecode(Request.QueryString["d"]); This works most of the time but every now and then we find one of the following two exceptions in our log: [FormatException: Invalid character in a Base-64 string.] System.Convert.FromBase64CharArray(Char[] inArray, Int32 offset, Int32 length) System.Web.HttpServerUtility.UrlTokenDecode(String input) ... [FormatException: Invalid length for a Base-64 char array.] System.Convert.FromBase64CharArray(Char[] inArray, Int32 offset, Int32 length) System.Web.HttpServerUtility.UrlTokenDecode(String input) System.Web.HttpServerUtilityWrapper.UrlTokenDecode(String input) ... Any ideas what would cause this phenomenon? Remarks: the resulting URL is < 1500, so below any known URL limits (e.g. IE: 2083) seems to be independent of user agent (we have these exceptions for IE6,7,8, FF & Chrome) our (unconfirmed) suspicions include AntiVirus products, HTTP proxies, browser addons found this remotely related question, but it's about a viewstate issue

• How do I get LongVarchar out param from SPROC in ADO.NET 2.0 with SQLAnywhere 10?

  - by todthomson

  Hi All, I have sproc 'up_selfassessform_view' which has the following parameters: in ai_eqidentkey SYSKEY in ai_acidentkey SYSKEY out as_eqcomments TEXT_STRING out as_acexplanation TEXT_STRING  -  which are domain objects - SYSKEY is 'integer' and TEXT_STRING is 'long varchar'. I can call the sproc fine from iSQL using the following code: create variable @eqcomments TEXT_STRING; create variable @acexamples TEXT_STRING; call up_selfassessform_view (75000146, 3, @eqcomments, @acexamples); select @eqcomments, @acexamples;  - which returns the correct values from the DB (so I know the SPROC is good). I have configured the out param in ADO.NET like so (which has worked up until now for 'integer', 'timestamp', 'varchar(255)', etc): SAParameter as_acexplanation = cmd.CreateParameter(); as_acexplanation.Direction = ParameterDirection.Output; as_acexplanation.ParameterName = "as_acexplanation"; as_acexplanation.SADbType = SADbType.LongVarchar; cmd.Parameters.Add(as_acexplanation); When I run the following code: SADataReader reader = cmd.ExecuteReader(); I receive the following error: Parameter[2]: the Size property has an invalid size of 0. Which (I suppose) makes sense... But the thing is, I don't know the size of the field (it's just "long varchar" it doesn't have a predetermined length - unlike varchar(XXX)). Anyhow, just for fun, I add the following: as_acexplanation.Size = 1000; and the above error goes away, but now when I call: as_acexplanation.Value i get back a string of length = 1000 which is just '\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0...' (\0 repeated 1000 times). So I'm really really stuck... Any help one this one would be much appreciated. Cheers! ;) Tod T.

• C++ -- Is there an implicit cast here from Fred* to auto_ptr<Fred>?

  Hello all, I saw the following code, #include <new> #include <memory> using namespace std; class Fred; // Forward declaration typedef auto_ptr<Fred> FredPtr; class Fred { public: static FredPtr create(int i) { return new Fred(i); // Is there an implicit casting here? If not, how can we return // a Fred* with return value as FredPtr? } private: Fred(int i=10) : i_(i) { } Fred(const Fred& x) : i_(x.i_) { } int i_; }; Please see the question listed in function create. Thank you // Updated based on comments Yes, the code cannot pass the VC8.0 error C2664: 'std::auto_ptr<_Ty::auto_ptr(std::auto_ptr<_Ty &) throw()' : cannot convert parameter 1 from 'Fred *' to 'std::auto_ptr<_Ty &' The code was copied from the C++ FAQ 12.15. However, after making the following changes, replace return new Fred(i); with return auto_ptr<Fred>(new Fred(i)); This code can pass the VC8.0 compiler. But I am not sure whether or not this is a correct fix.

• Getting the first result from a LINQ query - why does ElementAt<T>(0) fails when First<T>() succeeds

  - by Mr Roys

  I have a method AddStudent() which looks for a student with the same name and returns an existing student from the database if there is a student with the same name, otherwise it creates a new student and adds it to the database. I'm curious why se = students.First<StudentEntity>(); succeeds when se = students.ElementAt<StudentEntity>(0); fails when I try to get the first result from the LINQ query. Aren't the two methods the same? The full code for the method is shown below. public Student AddStudent(string name) { using (SchoolEntities db = new SchoolEntities()) { // find student with same name via LINQ var students = from s in db.StudentEntitySet where s.name == name select s; StudentEntity se = default(StudentEntity); // if student with the same name is already present, return // that student if (students.Count<StudentEntity>() > 0) { // if i use ElementAt, if fails with a "LINQ to Entities does not // recognize the method 'StudentEntity ElementAt[StudentEntity] // (System.Linq.IQueryable`1[StudentEntity], Int32)' method, // and this method cannot be translated into a store expression.", // but not when I use First. Why? // se = students.ElementAt<StudentEntity>(0); se = students.First<StudentEntity>(); } else { // passing 0 for first parameter (id) since it's represented by // a BigInt IDENTITY field in the database so any value // doesn't matter. se = StudentEntity.CreateStudentEntity(0, name); db.AddToStudentEntitySet(se); db.SaveChanges(); } // create a Student object from the Entity object return new Student(se); } } Thanks!

• GWT CssResource Customization

  - by Eric Landry

  I'm writing a GWT widget using UIBinder and MVP. The widget's default styles are defined in TheWidgetView.ui.xml: <ui:style type="com.widgetlib.spinner.display.TheWidgetView.MyStyle"> .textbox { border: 1px solid #red; } .important { font-weight: bold; } </ui:style> The widget's CssResource interface is defined in TheWidgetView.java: public class TheWidgetView extends HorizontalPanel implements TheWidgetPresenter.Display { // ... some code @UiField MyStyle style; public interface MyStyle extends CssResource { String textbox(); String important(); } // ... more code } I'd like the consumer of this widget to be able to customize part of the widget's styles and to have this in their MyExample.ui.xml: <ui:style type="com.consumer.MyExample.MyStyle"> .textbox { border: 2px solid #black; } </ui:style> And this be their MyExample.java: public class MyExample extends Composite { // ... some code @UiField MyStyle style; interface MyStyle extends TheWidgetView.MyStyle{ String textbox(); } // ... more code } Is there a way that my widget can have default styles, but that the consumer of the widget can override one of them? When an interface extends TheWidgetView.MyStyle, the of the widget consumer needs to define all the styles listed in that parent interface. I've seen some widget libraries have the widget's constructor take in a ClientBundle as parameter, which I suppose could apply to CssResource. Although, I'm not sure how I'd pass in this style object in a constructor invoked by UIBinder. Thanks much in advance!

• Does NHibernate LINQ support ToLower() in Where() clauses?

  - by Daniel T.

  I have an entity and its mapping: public class Test { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual string Description { get; set; } } public class TestMap : EntityMap<Test> { public TestMap() { Id(x => x.Id); Map(x => x.Name); Map(x => x.Description); } } I'm trying to run a query on it (to grab it out of the database): var keyword = "test" // this is coming in from the user keyword = keyword.ToLower(); // convert it to all lower-case var results = session.Linq<Test> .Where(x => x.Name.ToLower().Contains(keyword)); results.Count(); // execute the query However, whenever I run this query, I get the following exception: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index Am I right when I say that, currently, Linq to NHibernate does not support ToLower()? And if so, is there an alternative that allows me to search for a string in the middle of another string that Linq to NHibernate is compatible with? For example, if the user searches for kap, I need it to match Kapiolani, Makapuu, and Lapkap.

• GWT serialization issue

  - by Eddy

  I am having a heck of a time returning an ArrayList of objects that implement IsSerializable via RPC. The IsSerializable pojo contains one variable, a String, and has a 0 parameter constructor. I have removed the .gwt.rpc file from my war and still I get: com.google.gwt.user.client.rpc.SerializationException: Type 'com.test.myApp.client.model.Test' was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded. For security purposes, this type will not be serialized.: instance = com.test.myApp.client.model.Test@17a9692 at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter.serialize(ServerSerializationStreamWriter.java:610) I am using GWT 2.0.2 with jdk 1.6.0_18. Any ideas on what might be going on or what I am doing wrong? Here is the code for the Test class and the remote method is returning ArrayList. I even modified the code for it to just return one instance of Test with the same result: the exception above. package com.test.myApp.client.model; import com.google.gwt.user.client.rpc.IsSerializable; public class Test implements IsSerializable{ private String s; public Test() {} public Test(String s) { this.s = s; } public String getS() { return s; } public void setS(String s) { this.s = s; } } Greatly appreciate the help!

• When *not* to use prepared statements?

  - by Ben Blank

  I'm re-engineering a PHP-driven web site which uses a minimal database. The original version used "pseudo-prepared-statements" (PHP functions which did quoting and parameter replacement) to prevent injection attacks and to separate database logic from page logic. It seemed natural to replace these ad-hoc functions with an object which uses PDO and real prepared statements, but after doing my reading on them, I'm not so sure. PDO still seems like a great idea, but one of the primary selling points of prepared statements is being able to reuse them… which I never will. Here's my setup: The statements are all trivially simple. Most are in the form SELECT foo,bar FROM baz WHERE quux = ? ORDER BY bar LIMIT 1. The most complex statement in the lot is simply three such selects joined together with UNION ALLs. Each page hit executes at most one statement and executes it only once. I'm in a hosted environment and therefore leery of slamming their servers by doing any "stress tests" personally. Given that using prepared statements will, at minimum, double the number of database round-trips I'm making, am I better off avoiding them? Can I use PDO::MYSQL_ATTR_DIRECT_QUERY to avoid the overhead of multiple database trips while retaining the benefit of parametrization and injection defense? Or do the binary calls used by the prepared statement API perform well enough compared to executing non-prepared queries that I shouldn't worry about it? EDIT: Thanks for all the good advice, folks. This is one where I wish I could mark more than one answer as "accepted" — lots of different perspectives. Ultimately, though, I have to give rick his due… without his answer I would have blissfully gone off and done the completely Wrong Thing even after following everyone's advice. :-) Emulated prepared statements it is!

  - by Nathan Taylor

  This one seems painfully obvious to me, but for some reason I can't get it working the way I want it to. Perhaps it isn't possible the way I am doing it, but that seems unlikely. This question may be somewhat related: http://stackoverflow.com/questions/1274855/asp-net-mvc-model-binding-related-entities-on-same-page. I have an EditorTemplate to edit an entity with multiple related entity references. When the editor is rendered the user is given a drop down list to select related entities from, with the drop down list returning an ID as its value. <%=Html.DropDownListFor(m => m.Entity.ID)%> When the request is sent the form value is named as expected: "Entity.ID", however my strongly typed Model defined as an action parameter doesn't have Entity.ID populated with the value passed in the request. public ActionResult AddEntity(EntityWithChildEntities entityWithChildEntities) { } I tried fiddling around with the Bind() attribute and specified Bind(Include = "Entity.ID") on the entityWithChildEntities, but that doesn't seem to work. I also tried Bind(Include = "Entity"), but that resulted in the ModelBinder attempting to bind a full "Entity" definition (not surprisingly). Is there any way to get the default model binder to fill the child entity ID or will I need to add action parameters for each child entity's ID and then manually copy the values into the model definition?

• Encryption puzzle / How to create a PassStub for a Remote Assistance ticket

  - by Jon Clegg

  I am trying to create a ticket for Remote Assistance. Part of that requires creating a PassStub parameter. As of the documentation: http://msdn.microsoft.com/en-us/library/cc240115(PROT.10).aspx PassStub: The encrypted novice computer's password string. When the Remote Assistance Connection String is sent as a file over e-mail, to provide additional security, a password is used.<16 In part 16 they detail how to create as PassStub. In Windows XP and Windows Server 2003, when a password is used, it is encrypted using PROV_RSA_FULL predefined Cryptographic provider with MD5 hashing and CALG_RC4, the RC4 stream encryption algorithm. As PassStub looks like this in the file: PassStub="LK#6Lh*gCmNDpj" If you want to generate one yourself run msra.exe in Vista or run the Remote Assistance tool in WinXP. The documentation says this stub is the result of the function CryptEncrypt with the key derived from the password and encrypted with the session id (Those are also in the ticket file). The problem is that CryptEncrypt produces a binary output way larger then the 15 byte PassStub. Also the PassStub isn't encoding in any way I've seen before. Some interesting things about the PassStub encoding. After doing statistical analysis the 3rd char is always a one of: !#$&()+-=@^. Only symbols seen everywhere are: *_ . Otherwise the valid characters are 0-9 a-z A-Z. There are a total of 75 valid characters and they are always 15 bytes. Running msra.exe with the same password always generates a different PassStub, indicating that it is not a direct hash but includes the rasessionid as they say. Some other ideas I've had is that it is not the direct result of CryptEncrypt, but a result of the rasessionid in the MD5 hash. In MS-RA (http://msdn.microsoft.com/en-us/library/cc240013(PROT.10).aspx). The "PassStub Novice" is simply hex encoded, and looks to be the right length. The problem is I have no idea how to go from any hash to way the PassStub looks like.

• ArgumentOutOfRangeException when reading bytes from stream

  - by user345194

  I'm trying to read the response stream from an HttpWebResponse object. I know the length of the stream (_response.ContentLength) however I keep getting the following exception: Specified argument was out of the range of valid values. Parameter name: size While debugging, I noticed that at the time of the error, the values were as such: length = 15032 //the length of the stream as defined by _response.ContentLength bytesToRead = 7680 //the number of bytes in the stream that still need to be read bytesRead = 7680 //the number of bytes that have been read (offset) body.length = 15032 //the size of the byte[] the stream is being copied to The peculiar thing is that the bytesToRead and bytesRead variables are ALWAYS 7680, regardless of the size of the stream (contained in the length variable). Any ideas? Code: int length = (int)_response.ContentLength; byte[] body = null; if (length 0) { int bytesToRead = length; int bytesRead = 0; try { body = new byte[length]; using (Stream stream = _response.GetResponseStream()) { while (bytesToRead > 0) { // Read may return anything from 0 to length. int n = stream.Read(body, bytesRead, length); // The end of the file is reached. if (n == 0) break; bytesRead += n; bytesToRead -= n; } stream.Close(); } } catch (Exception exception) { throw; } } else { body = new byte[0]; } _responseBody = body;

• Using Mod-Rewrite in XAMPP

  - by rrrfusco

  I've followed some tutorials on how to use Mod_Rewrite, but it's not working out. I have a php index page that takes a page parameter like so: call: index?page=name1, name2, name3 etc. <?php if (isset($_GET['page'])) { switch($_GET['page']) { case 'front': include "front.php"; break; default: break; } } ? I'd like to run mod-rewrite so that the urls display as site.com/name1. Is this possible with the code i'm using above? Below is what I've been trying in the apache config files to no avail. apache/conf/http.conf line 122: LoadModule rewrite_module modules/mod_rewrite.so line 188: DocumentRoot "G:/xampp/htdocs" line 198: #default <Directory /> Options FollowSymLinks AllowOverride None Order deny,allow Deny from all </Directory> line 215: <Directory "G:/xampp/htdocs"> line 228: Options Indexes FollowSymLinks Includes ExecCGI line 235: AllowOverride All # cgi line 355: <Directory "G:/xampp/cgi-bin"> AllowOverride None Options None Order allow,deny Allow from all </Directory> G:\xampp\apache\conf\extra\http.v-hosts.conf <VirtualHost *:80> DocumentRoot G:/xampp/htdocs/ ServerName localhost ServerAdmin admin@localhost <Directory "G:/xampp/htdocs/localhost/"> Options Indexes FollowSymLinks AllowOverride FileInfo Order allow,deny Allow from all </Directory> </VirtualHost> <VirtualHost *:80> DocumentRoot G:/xampp/htdocs/site2/ ServerName site2.localhost ServerAdmin [email protected] <Directory "G:/xampp/htdocs/site2.localhost/"> Options Indexes FollowSymLinks AllowOverride FileInfo Order allow,deny Allow from all </Directory> </VirtualHost> .htaccess file IndexIgnore * RewriteEngine on RewriteRule ^([^/\.]+)/?$ /index.php?page=$1 [L]
