  • What is the best way to get support from microsoft developers [closed]

    - by Malcolm Frexner
    I have a problem at my production web, that I am not able to solve. I am not able to reproduce the problem in stage or development. It only appears when the website is under heavy load. I think it is solvable if somebody who has a very good understanding of the internals of FormsAuthentication would have a look at it by logging into our system. It should be at least Scottgu! Somebody told me that Microsoft Premier Support is a good choice for this kind of problems. We have no MSDN subscription or other connection to microsoft that enables us to use MPS. Is there a way to get support on a incident base? Are there other ways to get this kind of support? EDIT Here is the problem itself: http://stackoverflow.com/questions/2448720/different-users-get-the-same-cookie-value-in-aspxanonymous

  • Dynamically compose ASP MVC view based on context

    - by robertFall
    I have several views that are composed of several partial views based on context. For example, we have a Project view that shows all the details of a project, which includes the scalar values, name etc, and also all the assigned employees, tasks and/or clients. The problem I have is that certain types of project have all of the above sections while others have only two or even on section, ie. details only. What is the best way to compose the Projects master view? I don't want to have logic to check the project in the view. Is there a way to compose a view in code by programatically rendering the relevant partials and ignoring the rest? Otherwise are there any other ideas how to do this in a maintainable way? I could of course just render the partials using if statements to check if they apply, but that way the view contains VERY important logic. In another situation we want to use this method to display content based on the type of subscription a user has. Thanks!

  • Streaming content from (sharepoint) web part

    - by Mikko Rantanen
    How does one stream files, html or custom AJAX responses from web parts? Our current quick-and-very-dirty solution is to make the web part call the current page with certain query parameters, which the web part checks and instead of performing normal load it writes the required things to output and calls response end. This sounds bad since SharePoint might load other web parts and execute their code before reaching our web part. The web part is configured with data source settings which means the streaming context must be specific to the web part so it can acquire the correct data source settings.

  • T4 Controller Template to trigger View Generation

    - by DrydenMaker
    I have been using some customized MVC templates that really improve my productivity. However, I would like to take it to the next level. I generate a controller template for each table in my app. The controller has Edit, List, Details, and Delete actions. What I would like to do, is at the same time trigger the generation of the views for those actions. Does anyone have a reference or have suggestions on how this can be done?

  • HtmlHelper does not contain definition for "Action"

  • Replace relative urls to absolute

    - by Rocky Singh
    I have the html source of a page in a form of string with me: <html> <head> <link rel="stylesheet" type="text/css" href="/css/all.css" /> </head> <body> <a href="/test.aspx">Test</a> <a href="http://mysite.com">Test</a> <img src="/images/test.jpg"/> <img src="http://mysite.com/images/test.jpg"/> </body> </html> I want to convert all the relative paths to absolute. I want the output be: <html> <head> <link rel="stylesheet" type="text/css" href="http://mysite.com/css/all.css" /> </head> <body> <a href="http://mysite.com/test.aspx">Test</a> <a href="http://mysite.com">Test</a> <img src="http://mysite.com/images/test.jpg"/> <img src="http://mysite.com/images/test.jpg"/> </body> </html> Note: I want only the relative paths to be converted to absolute ones in that string. The absolute ones which are already in that string should not be touched, they are fine to me as they are already absolute. Can this be done by regex or other means?

  • Error when passing quotes to webservice by AJAX

    - by Radu
    I'm passing data using .ajax and here are my data and contentType attributes: data: '{ "UserInput" : "' + $('#txtInput').val() + '","Options" : { "Foo1":' + bar1 + ', "Foo2":' + Bar2 + ', "Flags":"' + flags + '", "Immunity":' + immunity + '}}', contentType: 'application/json; charset=utf-8', Server side my code looks like this: <WebMethod()> _ Public Shared Function ParseData(ByVal UserInput As String, ByVal Options As Options) As String The userinput is obvious but the Options structure is like the following: Public Structure Options Dim Foo1 As Boolean Dim Foo2 As Boolean Dim Flags As String Dim Immunity As Integer End Structure Everything works fine when $('#txtInput') contains no double-quotes but if they are present I get an error (for an input of asd"): {"Message":"Invalid object passed in, \u0027:\u0027 or \u0027}\u0027 expected. (22): { \"UserInput\" : \"asd\"\",\"Options\" : { \"Foo1\":false, \"Foo2\":false, \"Flags\":\"\", \"Immunity\":0}}","StackTrace":" at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeDictionary(Int32 depth)\r\n at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth)\r\n at System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(String input, Int32 depthLimit, JavaScriptSerializer serializer)\r\n at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T](String input)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.ArgumentException"} Any idea how I can avoid this error? Also, when I pass the same input with quotes directly it works fine.

  • How to declare a generic constraint that is a generic type

    - by HackedByChinese
    I have a two generic abstract types: Entity and Association. Let's say Entity looks like this: public class Entity<TId> { //... } and Association looks like this: public class Association<TEntity, TEntity2> { //... } How do I constrain Association so they can be of any Entity? I can accomplish it by the following: public class Association<TEntity, TId, TEntity2, TId2> where TEntity : Entity<TId> where TEntity2: Entity<TId2> { //... } This gets very tedious as more types derive from Association, because I have to keep passing down TId and TId2. Is there a simpler way to do this, besides just removing the constraint?

    - by kumar
    Hi all, (LocalVariable)ABC.string(Name)= (Idatareader)datareader.GetString(0); this name value is coming from database.. what happening here is if this name value is null while reading it's throwing an exception? I am manually doing some if condition here. I don't want to write a manual condition to check all my variables.. I am doing something like this now.. string abc = (Idatareader)datareader.GetValue(0); if(abc = null) //assiging null else assiging abc value is there something like can we write extension method for this? thanks

  • Authenticating to multiple OUs in Active Directory

    - by Jaxidian
    I'm using the Active Directory Membership Provider with the following configuration: <connectionStrings> <add name="MyConnString" connectionString="LDAP://domaincontroller/OU=Product Users,DC=my,DC=domain,DC=com" /> </connectionStrings> <membership defaultProvider="MyProvider"> <providers> <clear /> <add name="MyProvider" connectionStringName="MyConnString" connectionUsername="my.domain.com\service_account" connectionPassword="biguglypassword" type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> </providers> </membership> This works perfectly except it requires ALL of my users to be in the "Product Users" OU when I would actually like to have all of my users organized into various child OUs under our "Product Users" OU. Is this possible? (Note that this is a partial repost of this question but the question I'm asking here was never answered there.)

  • Comparison operators not supported for type IList when Paging data in Linq to Sql

    - by Dan
    I can understand what the error is saying - it can't compare a list. Not a problem, other than the fact that I don't know how to not have it compare a list when I want to page through a model with a list as a property. My Model: Event : IEvent int Id string Title // Other stuff.. LazyList<EventDate> Dates // The "problem" property Method which pages the data (truncated): public JsonResult JsonEventList(int skip, int take) { var query = _eventService.GetEvents(); // Do some filtering, then page data.. query = query.Skip(skip).Take(take); return Json(query.ToArray()); } As I said, the above is truncated quite a bit, leaving only the main point of the function: filter, page and return JSON'd data. The exception occurs when I enumerate (.ToArray()). The Event object is really only used to list the common objects of all the event types (Meetings, Birthdays, etc - for example). It still implements IEvent like the other types, so I can't just remove the LazyList<EventDate> Dates' property unless I no longer implementIEvent` Anyway, is there a way to avoid this? I don't really want to compare a LazyList when I page, but I do not know how to resolve this issue. Thank you in advance! :)

  • Why is Delphi unable to infer the type for a parameter TEnumerable<T>?

    - by deepc
    Consider the following declaration of a generic utility class in Delphi 2010: TEnumerableUtils = class public class function InferenceTest<T>(Param: T): T; class function Count<T>(Enumerable: TEnumerable<T>): Integer; overload; class function Count<T>(Enumerable: TEnumerable<T>; Filter: TPredicate<T>): Integer; overload; end; Somehow the compiler type inference seems to have problems here: var I: Integer; L: TList<Integer>; begin TEnumerableUtils.InferenceTest(I); // no problem here TEnumerableUtils.Count(L); // does not compile: E2250 There is no overloaded version of 'Count' that can be called with these arguments TEnumerableUtils.Count<Integer>(L); // compiles fine end; The first call works as expected and T is correctly inferred as Integer. The second call does not work, unless I also add <Integer -- then it works, as can be seen in the third call. Am I doing something wrong or is the type inference in Delphi just not supporting this (I don't think it is a problem in Java which is why expected it to work in Delphi, too).

  • Differentiate generic methods by type parameters only using reflection?

    - by Brian Vallelunga
    I'm trying to use reflection to get a specific MethodInfo of a class, but am unsure how to differentiate between the two following methods: public class Test { public IBar<T1> Foo<T1>(); public IBar<T1, T2> Foo<T1, T2>(); } How can I get a reference to the different Foo methods, assuming I know the number of type parameters? Just calling typeof(Test).GetMethod("Foo") will throw an exception that the method name is ambiguous and there aren't a differing number of parameters to check.

  • Generic InBetween Function.

    - by Luiscencio
    I am tired of writing x > min && x < max so i wawnt to write a simple function but I am not sure if I am doing it right... actually I am not cuz I get an error: bool inBetween<T>(T x, T min, T max) where T:IComparable { return (x > min && x < max); } errors: Operator '>' cannot be applied to operands of type 'T' and 'T' Operator '<' cannot be applied to operands of type 'T' and 'T' may I have a bad understanding of the where part in the function declaring note: for those who are going to tell me that I will be writing more code than before... think on readability =) any help will be appreciated EDIT deleted cuz it was resolved =) ANOTHER EDIT so after some headache I came out with this (ummm) thing following @Jay Idea of extreme readability: public static class test { public static comparision Between<T>(this T a,T b) where T : IComparable { var ttt = new comparision(); ttt.init(a); ttt.result = a.CompareTo(b) > 0; return ttt; } public static bool And<T>(this comparision state, T c) where T : IComparable { return state.a.CompareTo(c) < 0 && state.result; } public class comparision { public IComparable a; public bool result; public void init<T>(T ia) where T : IComparable { a = ia; } } } now you can compare anything with extreme readability =) what do you think.. I am no performance guru so any tweaks are welcome

  • 'Lexical' scoping of type parameters in C#

    - by leppie
    I have 2 scenarios. This fails: class F<X> { public X X { get; set; } } error CS0102: The type 'F' already contains a definition for 'X' This works: class F<X> { class G { public X X { get; set; } } } The only logical explanation is that in the second snippet the type parameter X is out of scope, which is not true... Why should a type parameter affect my definitions in a type? IMO, for consistency, either both should work or neither should work. Any other ideas? PS: I call it 'lexical', but it probably is not not the correct term.

  • How to extend this design for a generic converter in java?

    - by Jay
    Here is a small currency converter piece of code: public enum CurrencyType { DOLLAR(1), POUND(1.2), RUPEE(.25); private CurrencyType(double factor) { this.factor = factor; } private double factor; public double getFactor() { return factor; } } public class Currency { public Currency(double value, CurrencyType type) { this.value = value; this.type = type; } private CurrencyType type; private double value; public CurrencyType getCurrencyType() { return type; } public double getCurrencyValue() { return value; } public void setCurrenctyValue(double value){ this.value = value; } } public class CurrencyConversion { public static Currency convert(Currency c1, Currency c2) throws Exception { if (c1 != null && c2 != null) { c2.setCurrenctyValue(c1.getCurrencyValue() * c1.getCurrencyType().getFactor() * c2.getCurrencyType().getFactor()); return c2; } else throw new Exception(); } } I would like to improve this code to make it work for different units of conversion, for example: kgs to pounds, miles to kms, etc etc. Something that looks like this: public class ConversionManager<T extends Convertible> { public T convert(T c1, T c2) { //return null; } } Appreciate your ideas and suggestions.
