• Regex matching into multiple groups per line?

  - by dmose

  I'm trying to come up with a regex to be able to parse the following type of strings into groups. <link rel="alternate" type="application/rss+xml" title="[!PageTitle!]" href="[!SiteRoot!]/feed.xml" /> My regular expression is: \[\!(.+)\!\] The problem with this expression is that it seems to pull it all into 1 group: Found 1 match: "[!PageTitle!]" href="[!SiteRoot!]" has 1 group: 1. "PageTitle!]" href="[!SiteRoot" I want dont want the regex to continue...am I missing a boundary? Ideally I want it to find 2 groups, [!PageTitle!] and [!SiteRoot!]

• Is it possible to implement X-HTTP-Method-Override in ASP.NET MVC?

  - by Greg Beech

  I'm implementing a prototype of a RESTful API using ASP.NET MVC and apart from the odd bug here and there I've achieve all the requirements I set out at the start, apart from callers being able to use the X-HTTP-Method-Override custom header to override the HTTP method. What I'd like is that the following request... GET /someresource/123 HTTP/1.1 X-HTTP-Method-Override: DELETE ...would be dispatched to my controller method that implements the DELETE functionality rather than the GET functionality for that action (assuming that there are multiple methods implementing the action, and that they are marked with different [AcceptVerbs] attributes). So, given the following two methods, I would like the above request to be dispatched to the second one: [ActionName("someresource")] [AcceptVerbs(HttpVerbs.Get)] public ActionResult GetSomeResource(int id) { /* ... */ } [ActionName("someresource")] [AcceptVerbs(HttpVerbs.Delete)] public ActionResult DeleteSomeResource(int id) { /* ... */ } Does anybody know if this is possible? And how much work would it be to do so...?

• ListView control rendering issue with Groups, CheckBoxes and View mode SmallIcon

  - by volody

  Microsoft MSDN site has next remark: "Any groups assigned to a ListView control appear whenever the ListView.View property is set to a value other than View.List." My problem is that i like to have View set to SmallIcon. In this mode ListView control is shifted left, and CheckBoxes are covered by left edge How to solve this issue, or at least how is possible to shift rendering of control to the right. My OS is Windows XP Service Pack 3. It looks like that ListView items with Groups and CheckBoxes shows correctly only when View set to Details.

• Creating items in groups in Rails

  - by LearnRails

  My product table is id type price location 1 chips $3 aisle3 I have a question with adding the products in groups. There is a quantity field(nonmodel) where the user can enter the quantity While adding a new product if the user enters: type: soda quantity: 3 Then there 3 records should be created in product model with type= soda like the following. id type 2 soda 3 soda 4 soda If user enters location: aisle4 quantity: 2 Then id location 5 ailse4 6 ailse4 Can you tell me how to pass the nonmodel field 'quantity' to the rails(model or controller) and how use it to add the products in groups as mentioned above? or should I create a column called quantity in my product table? Will the history be updated too for all these new records with after_create filter which I already have ? Is there any good tutorial or book which shows how to pass such nonmodel html/javascript fields from view to rails and then back to the view? Any help will be greatly appreciated. Thanks

• Javascript static method intheritance

  - by Matteo Pagliazzi

  I want to create a javascript class/object that allow me to have various method: Model class Model.all() » static method Model.find() » static method Model delete() » instance method Model save() » instance method Model.create() » static that returns a new Model instance For static method I can define them using: Model.staticMethod(){ method } while for instance method is better to use: function Model(){ this.instanceMethod = function(){} } and then create a new instance or using prototype? var m = function Model(){ } m.prototype.method() = function(){ } Now let's say that I want to create a new class based on Model, how to inherit not only its prototypes but also its static methods?

• Is any simple way to create method and set its body dynamically in C#?

  - by greatromul

  I hold body of method in string. I want to create method dynamically. But I don't know, how to set its body. I saw very tedious way using CodeDom. And I saw using Emit with OpCodes. Is any way to use ready code from string variable? string method_body = "return \"Hello, world!\";"; //there is method body DynamicMethod dm = new System.Reflection.Emit.DynamicMethod("My_method", typeof(string), new Type[] { }); //any way to create method dynamically //any way to set body string result = (string)dm.Invoke(...); //I need write result in variable

• Algorithm to split an array into N groups based on item index (should be something simple)

  - by serg

  I feel that it should be something very simple and obvious but just stuck on this for the last half an hour and can't move on. All I need is to split an array of elements into N groups based on element index. For example we have an array of 30 elements [e1,e2,...e30], that has to be divided into N=3 groups like this: group1: [e1, ..., e10] group2: [e11, ..., e20] group3: [e21, ..., e30] I came up with nasty mess like this for N=3 (pseudo language, I left multiplication on 0 and 1 just for clarification): for(i=0;i<array_size;i++) { if(i>=0*(array_size/3) && i<1*(array_size/3) { print "group1"; } else if(i>=1*(array_size/3) && i<2*(array_size/3) { print "group2"; } else if(i>=2*(array_size/3) && i<3*(array_size/3) print "group3"; } } But what would be the proper general solution? Thanks.

• Set NTFS Permissions with DirectorySecurity after created Active Dirctory Groups c#

  - by maverick

  Hi I am a little confused about setting NTFS Permissions to a directory after I created Active Directory Groups (both programmatically). When I created the Active Directory Objects then I have to wait a few seconds to set the NTFS Permissions. If I have not this timeout then I get sometimes an error message that the identify (active directory groupname) could not found. Is it possible that the DirectorySecurity-Class from DirectoryInfo-Class has an different algorithm to get the idenfity from active directory objects? Because when I checking the existing of the groups in active directory with System.DirectoryServices all the objects exist suddenly after creation. Kind regards

• How is it possible to list all folders that a particular user/group has permissions on?

  - by Lord Torgamus

  Is it possible to list all folders/files that a given group has explicit permissions on, for a machine running Windows Server 2003? If so, how? It would be nice to see inherited permissions as well, but I could do with just explicit permissions. A little background: I'm trying to update groups/permissions on a test server. One of the groups, Devs, wasn't implemented correctly when it was created, and my goal is to remove it from the system. It has been replaced by LeadDevelopers, which has permissions on many — but naturally not all — of the same folders. I want to make sure that I don't accidentally orphan any folders or cause any other issues when I remove Devs. It did have some admin-level permissions. EDIT: The answers so far — at least *cacls and AccessEnum — provide a way to find out which groups/users have permissions on known directories/files. I actually want the reverse of this behavior: I know the group, and I'm looking for the directories/files for which the group has permissions. Also, as I noted in a comment, the Devs group is not itself a member of any other group.

• In Ruby, why is a method invocation not able to be treated as a unit when "do" and "end" is used?

  - by Jian Lin

  The following question is related to the question "Ruby Print Inject Do Syntax". My question is, can we insist on using do and end and make it work with puts or p? This works: a = [1,2,3,4] b = a.inject do |sum, x| sum + x end puts b # prints out 10 so, is it correct to say, inject is an instance method of the Array object, and this instance method takes a block of code, and then returns a number. If so, then it should be no different from calling a function or method and getting back a return value: b = foo(3) puts b or b = circle.getRadius() puts b In the above two cases, we can directly say puts foo(3) puts circle.getRadius() so, there is no way to make it work directly by using the following 2 ways: a = [1,2,3,4] puts a.inject do |sum, x| sum + x end but it gives ch01q2.rb:7:in `inject': no block given (LocalJumpError) from ch01q2.rb:4:in `each' from ch01q2.rb:4:in `inject' from ch01q2.rb:4 grouping the method call using ( ) doesn't work either: a = [1,2,3,4] puts (a.inject do |sum, x| sum + x end) and this gives: ch01q3.rb:4: syntax error, unexpected kDO_BLOCK, expecting ')' puts (a.inject do |sum, x| ^ ch01q3.rb:4: syntax error, unexpected '|', expecting '=' puts (a.inject do |sum, x| ^ ch01q3.rb:6: syntax error, unexpected kEND, expecting $end end) ^ finally, the following version works: a = [1,2,3,4] puts a.inject { |sum, x| sum + x } but why doesn't the grouping of the method invocation using ( ) work in the earlier example? What if a programmer insist that he uses do and end, can it be made to work?

• Call instance method with objc_msgSend

  - by user772349

  I'm trying to use the objc_msgSend method to call some method dynamically. Say I want call some method in Class B from Class A and there are two methods in class B like: - (void) instanceTestWithStr1:(NSString *)str1 str2:(NSString *)str1; + (void) methodTestWithStr1:(NSString *)str1 str2:(NSString *)str1; And I can call the class method like this in Class A successfully: objc_msgSend(objc_getClass("ClassB"), sel_registerName("methodTestWithStr1:str2:"), @"111", @"222"); And I can call the instance method like this in Class A successfully as well: objc_msgSend([[objc_getClass("ClassB") alloc] init], sel_registerName("instanceTestWithStr1:str2:"), @"111", @"222"); But the thing is to get a instance of Class B I have to call "initWithXXXXX:XXXXXX:XXXXXX" instead of "init" so that to pass some necessary parameters to class B to do the init stuff. So I stored a instance of ClassB in class A as variable: self.classBInstance = [[ClassB alloc] initWithXXXXX:XXXXXX:XXXXXX]; And then I call the method like this (successfully): The problem is, I want to call a method by simply applying the classname and the method sel like "ClassName" and "SEL" and then call it dynamically: If it's a class method. then call it like: objc_msgSend(objc_getClass("ClassName"), sel_registerName("SEL")); If it's a instance method, find the existing class instance variable in the calling class then: objc_msgSend([self.classInstance, sel_registerName("SEL")); So I want to know if there is any way to: Check if a class has a given method (I found "responseToSelector" will be the one) Check if a given method in class method or instance method (maybe can use responseToSelector as well) Check if a class has a instance variable of a given class So I can call a instance method like: objc_msgSend(objc_getClassInstance(self, "ClassB"), sel_registerName("SEL"));

• login with users, groups and permissions

  - by Dan Bemowski

  OK, I have a set of tables that I want to use for my user logins. I am guessing that I need a separate model for each table in the database. My tables are as follows: Users - user information such as first and last name, groups_id, status, etc... groups - defines the user groups with id, name, description permissions - defines a list of permissions that a group can have permission_assignments - groups_id and permissions_id. many to many relationship table I am not sure how to go about populating an array that would contain the list of permissions that a user would have based on the group they are in after a successful login. Basically, a user belongs to a group, and the group gets assigned permissions. I want to then be able to validate functions/methods based on weather the logged in user has certain permissions. Any help is appreciated

• No input method choice appear on iBus

  - by phanect

  I've installed iBus and ibus-mozc, and an input method engine of Japanese from the repository, and attempted to enable mozc from Preference > "Input Method" tab > "Select Input Method" combo box. However, there is no choice to select, so I couldn't enable mozc. I also tried ibus-anthy, another legacy Japanese input method, but the situation was the same and I couldn't use anthy. Same problem is also occuring in openSUSE 12.1, so I don't think this is distribution-specific problem. In addition, this trouble also happened when I installed ibus-pynin, so this is not Japanese-specific. Any idea to find the cause of this trouble?

• Default Parameters vs Method Overloading

  - by João Angelo

  With default parameters introduced in C# 4.0 one might be tempted to abandon the old approach of providing method overloads to simulate default parameters. However, you must take in consideration that both techniques are not interchangeable since they show different behaviors in certain scenarios. For me the most relevant difference is that default parameters are a compile time feature while method overloading is a runtime feature. To illustrate these concepts let’s take a look at a complete, although a bit long, example. What you need to retain from the example is that static method Foo uses method overloading while static method Bar uses C# 4.0 default parameters. static void CreateCallerAssembly(string name) { // Caller class - Invokes Example.Foo() and Example.Bar() string callerCode = String.Concat( "using System;", "public class Caller", "{", " public void Print()", " {", " Console.WriteLine(Example.Foo());", " Console.WriteLine(Example.Bar());", " }", "}"); var parameters = new CompilerParameters(new[] { "system.dll", "Common.dll" }, name); new CSharpCodeProvider().CompileAssemblyFromSource(parameters, callerCode); } static void Main() { // Example class - Foo uses overloading while Bar uses C# 4.0 default parameters string exampleCode = String.Concat( "using System;", "public class Example", "{{", " public static string Foo() {{ return Foo(\"{0}\"); }}", " public static string Foo(string key) {{ return \"FOO-\" + key; }}", " public static string Bar(string key = \"{0}\") {{ return \"BAR-\" + key; }}", "}}"); var compiler = new CSharpCodeProvider(); var parameters = new CompilerParameters(new[] { "system.dll" }, "Common.dll"); // Build Common.dll with default value of "V1" compiler.CompileAssemblyFromSource(parameters, String.Format(exampleCode, "V1")); // Caller1 built against Common.dll that uses a default of "V1" CreateCallerAssembly("Caller1.dll"); // Rebuild Common.dll with default value of "V2" compiler.CompileAssemblyFromSource(parameters, String.Format(exampleCode, "V2")); // Caller2 built against Common.dll that uses a default of "V2" CreateCallerAssembly("Caller2.dll"); dynamic caller1 = Assembly.LoadFrom("Caller1.dll").CreateInstance("Caller"); dynamic caller2 = Assembly.LoadFrom("Caller2.dll").CreateInstance("Caller"); Console.WriteLine("Caller1.dll:"); caller1.Print(); Console.WriteLine("Caller2.dll:"); caller2.Print(); } And if you run this code you will get the following output: // Caller1.dll: // FOO-V2 // BAR-V1 // Caller2.dll: // FOO-V2 // BAR-V2 You see that even though Caller1.dll runs against the current Common.dll assembly where method Bar defines a default value of “V2″ the output show us the default value defined at the time Caller1.dll compiled against the first version of Common.dll. This happens because the compiler will copy the current default value to each method call, much in the same way a constant value (const keyword) is copied to a calling assembly and changes to it’s value will only be reflected if you rebuild the calling assembly again. The use of default parameters is also discouraged by Microsoft in public API’s as stated in (CA1026: Default parameters should not be used) code analysis rule.

• Method flags as arguments or as member variables?

  - by Martin

  I think the title "Method flags as arguments or as member variables?" may be suboptimal, but as I'm missing any better terminology atm., here goes: I'm currently trying to get my head around the problem of whether flags for a given class (private) method should be passed as function arguments or via member variable and/or whether there is some pattern or name that covers this aspect and/or whether this hints at some other design problems. By example (language could be C++, Java, C#, doesn't really matter IMHO): class Thingamajig { private ResultType DoInternalStuff(FlagType calcSelect) { ResultType res; for (... some loop condition ...) { ... if (calcSelect == typeA) { ... } else if (calcSelect == typeX) { ... } else if ... } ... return res; } private void InteralStuffInvoker(FlagType calcSelect) { ... DoInternalStuff(calcSelect); ... } public void DoThisStuff() { ... some code ... InternalStuffInvoker(typeA); ... some more code ... } public ResultType DoThatStuff() { ... some code ... ResultType x = DoInternalStuff(typeX); ... some more code ... further process x ... return x; } } What we see above is that the method InternalStuffInvoker takes an argument that is not used inside this function at all but is only forwarded to the other private method DoInternalStuff. (Where DoInternalStuffwill be used privately at other places in this class, e.g. in the DoThatStuff (public) method.) An alternative solution would be to add a member variable that carries this information: class Thingamajig { private ResultType DoInternalStuff() { ResultType res; for (... some loop condition ...) { ... if (m_calcSelect == typeA) { ... } ... } ... return res; } private void InteralStuffInvoker() { ... DoInternalStuff(); ... } public void DoThisStuff() { ... some code ... m_calcSelect = typeA; InternalStuffInvoker(); ... some more code ... } public ResultType DoThatStuff() { ... some code ... m_calcSelect = typeX; ResultType x = DoInternalStuff(); ... some more code ... further process x ... return x; } } Especially for deep call chains where the selector-flag for the inner method is selected outside, using a member variable can make the intermediate functions cleaner, as they don't need to carry a pass-through parameter. On the other hand, this member variable isn't really representing any object state (as it's neither set nor available outside), but is really a hidden additional argument for the "inner" private method. What are the pros and cons of each approach?

• Why the R# Method Group Refactoring is Evil

  - by Liam McLennan

  The refactoring I’m talking about is recommended by resharper when it sees a lambda that consists entirely of a method call that is passed the object that is the parameter to the lambda. Here is an example: public class IWishIWasAScriptingLanguage { public void SoIWouldntNeedAllThisJunk() { (new List<int> {1, 2, 3, 4}).Select(n => IsEven(n)); } private bool IsEven(int number) { return number%2 == 0; } } When resharper gets to n => IsEven(n) it underlines the lambda with a green squiggly telling me that the code can be replaced with a method group. If I apply the refactoring the code becomes: public class IWishIWasAScriptingLanguage { public void SoIWouldntNeedAllThisJunk() { (new List<int> {1, 2, 3, 4}).Select(IsEven); } private bool IsEven(int number) { return number%2 == 0; } } The method group syntax implies that the lambda’s parameter is the same as the IsEven method’s parameter. So a readable, explicit syntax has been replaced with an obfuscated, implicit syntax. That is why the method group refactoring is evil.
