  • how to have minimum AreaRegistrations with putting duplicated elements in single place

    - by Sadegh
    hi all, i have several AreaRegistration classes which one each registers own routes and each one have some duplicated elements such as bolded text in below: context.MapRoute("Search", "**{culture}/{style}**/search", new { **culture = cultureValue, style = styleValue,** controller = "search", action = "default" }, new { **culture = new CultureRouteConstraint(), style = new StyleRouteConstraint()** }); how i can have minimum AreaRegistrations with putting duplicated elements in single place which handles that? this is possible?

  • Call Generic method using runtime type and cast return object

    - by markpirvine
    I'm using reflection to call a generic method with a type determined at runtime. My code is as follows: Type tType = Type.GetType(pLoadOut.Type); MethodInfo method = typeof(ApiSerialiseHelper).GetMethod("Deserialise", new Type[] { typeof(string) }); MethodInfo generic = method.MakeGenericMethod(tType); generic.Invoke(obj, new object[] { pLoadOut.Data }); This works ok. However the generic.Invoke method returns an object, but what I would like is the type determined at runtime. Is this possible with this approach, or is there a better option? Mark

  • Generic type parameter naming convention for Java (with multiple chars)?

    - by chaper29
    In some interfaces i wrote I'd like to name generic type parameter with more than one character to make the code more readable. Something like.... Map<Key,Value> Instead of this... Map<K,V> But when it comes to methods, the type-parameters look like java-classes which is also confusing. public void put(Key key, Value value) This seems like Key and Value are classes. I found or thought of some notations, but nothing like a convention from sun or a general best-practice. Alternatives i guesed of or found... Map<KEY,VALUE> Map<TKey,TValue>

  • Generic object comparison diff routine

    - by MicMit
    The question stems from database tables comparison. Let's say we put left row in the instance Left and the right one into instance Right of the same type. And we'got many tables and respective types. How to implement more or less generic routine resulting in a collection of diffs e.g. propertyName , leftValue , rightValue for each such a pair of instances of the same type.

  • Need to call Silverlight Handler event and then serverside event on Page submit.

    - by Shivkant
    I have a Silverlight control on page which has a upload control. the silverlight exposes some events such as StartUpload() = To start the file upload, StopUpload() = To stop the file upload if running, CheckFileStatus() = to check the status of the file upload. The page has aspx Submit button with onclientclick event and ocClick event. <asp:Button ID="btn_upload" Text="External Upload" runat="server" OnClientClick="Javascript:StartUpload();" OnClick="btn_upload_Click" /> When I click on the aspx Submit Button, the file selected in Silverlight control should be uploaded and after the completion of upload, the Server side event should get called. I tried for it but was not able to do so. Please help me out!....

  • Get a property value with only the object and the name of the property (but not the type)

    - by Vaccano
    Suppose I have a method that passes in the name of a property (as a string) and the object that the property is on (as object). How could I get the value of the property? Here is some code to make it a bit more concrete: protected override void Paint(Graphics g, Rectangle bounds, CurrencyManager source, int rowNum, Brush backBrush, Brush foreBrush, bool alignToRight) { // The next line is made up code var currentValue = source.Current.CoolMethodToTakePropertyNameAndReturnValue(MappingName); // Paint out the retrieved value g.DrawString(currentValue.ToString() , _gridFont, new SolidBrush(Color.Black), bounds.Left + 1, bounds.Top); } MappingName is the name of the property I want to get the value for. What I need is CoolMethodToTakePropertyNameAndReturnValue. Any ideas? I am running on the Compact Framework. I would also prefer to avoid reflection (but if that is my only recourse then so be it). Thanks for any help.

  • implict type cast in generic method

    - by bitbonk
    why do I get a compiler error in the following code stating: Cannot implicty convert type SpecialNode to T even though T must derive from NodeBase as I defined in the where clause and even though SpecialNode actually derived from NodeBase? public static T GetNode<T>() where T : NodeBase { if (typeof(T) == typeof(SpecialNode)) { return ThisStaticClass.MySpecialNode; // <-- compiler error } if (typeof(T) == typeof(OtherSpecialNode)) { return ThisStaticClass.MyOtherSpecialNode; // <-- compiler error } ... return default(T); }

  • How do I access static variables in an enum class without a class instance?

    - by krick
    I have some code that processes fixed length data records. I've defined the record structures using java enums. I've boiled it down the the simplest example possible to illustrate the hoops that I currently have to jump through to get access to a static variable inside the enum. Is there a better way to get at this variable that I'm overlooking? If you compile and run the code, it just prints out "3". Note: the "code" tag doesn't seem to want to format this properly, but it should compile. class EnumTest { private interface RecordLayout { public int length(); } private enum RecordType1 implements RecordLayout { FIELD1 (2), FIELD2 (1), ; private int length; private RecordType1(int length) { this.length = length; } public int length() { return length; } public static int LEN = 3; } private static <E extends Enum<E> & RecordLayout> String parse(String data, Class<E> record) { // ugly hack to get at LEN... try { int len = record.getField("LEN").getInt(record); System.out.println(len); } catch (Exception e) { System.out.println(e); } String results = ""; for (E field: record.getEnumConstants()) { // do some stuff with the fields } return results; } public static void main(String args[]) { parse("ABC", RecordType1.class); } }

  • C# Improved algorithm

    - by generixs
    I have been asked at interview (C# 3.0) to provide a logic to remove a list of items from a list. I responded int[] items={1,2,3,4}; List<int> newList = new List<int>() { 1, 2, 3, 4, 5, 56, 788, 9 }; newList.RemoveAll((int i) => { return items.Contains(i); }); 1) The interviewer replied that the algorithm i had employed will gradually take time if the items grow and asked me to give even better and faster one.What would be the efficient algorithm ? 2) How can i achieve the same using LINQ? 3) He asked me to provide an example for Two-Way-Closure? (General I am aware of closure, what is Two-Way-Closure?, I replied there is no such term exists,but he did not satisfy).

  • Will [WithEvents = Nothing] RemoveHandlers in the derived class?

    - by serhio
    I use to set WithEvents variables to Nothing in Destuctor, because this will "Remove" all the Handlers associated with Handles keyword. Will this have the same effect for derivated classes? Class A Protected WithEvents _Foo as Button Private Sub _Foo_Click Handles _Foo.Click ' ... some Click action ' End Sub Public Sub Dispose(disposing as Boolean) If disposing then _Foo = Nothing ' remove handler _Foo_Click ' End Sub End Class Class B Inherits A Private Sub _Foo_Move Handles _Foo.Move ' ... some Move action ' End Sub ' ????? will or NOT remove OR handler _Foo_Move the base Dispose??' Public Overrides Sub Dispose(disposing as Boolean) 'If disposing then _Foo = Nothing ' MyBase.Dispose(disposing) End Sub End Class

  • MVC can't find my Areas page

    - by Steven
    I created an Area in my application named Admin. It's pretty basic, looks like this: Areas Admin Controllers CompaniesController.cs Models Views Companies Index.aspx AdminAreaRegistration.cs When I try to view my Index page by going to /Admin/Companies, I get a "The resource cannot be found" message. I find it weird that I don't get any sort of error message. I'm not sure what's going on here, has anyone come across this?

  • Generic list/sublist handling

    - by user628661
    Let's say we have a class class ComplexCls { public int Fld1; public string Fld2; //could be more fields } class Cls { public int SomeField; } and then some code class ComplexClsList: List<ComplexCls>; ComplexClsList myComplexList; // fill myComplexList // same for Cls class ClsList : List<Cls>; ClsList myClsList; We want to populate myClsList from myComplexList, something like (pseudocode): foreach Complexitem in myComplexList { Cls ClsItem = new Cls(); ClsItem.SomeField = ComplexItem.Fld1; } The code to do this is easy and will be put in some method in myClsList. However I'd like to design this as generic as possible, for generic ComplexCls. Note that the exact ComplexCls is known at the moment of using this code, only the algorithm shd be generic. I know it can be done using (direct) reflection but is there other solution? Let me know if the question is not clear enough. (probably isn't). [EDIT] Basically, what I need is this: having myClsList, I need to specify a DataSource (ComplexClsList) and a field from that DataSource (Fld1) that will be used to populate my SomeField
