问题 Hi and thanks for taking the time to asnwer my question. I have the following problem. I have a form and a button which says "add new activities".

Cannot convert system.Collections.ObjectModel.ReadOnlyCollection to System.Collections.Generic.List Then I have tried

问题 Is it possible to have class A with an empty method say render() .. then you create 3 instances of the class, so you have objects b, c, d , so can I THEN assign bodies for the render method for each object? Here's an example, in JavaScript you can have an object say a and then anywhere you can say a.method = function() { /* do something */ } After that line, you will have a method with the name method for the object a and whenever called it will /* do something */ . Is this possible in Java

This is the code from the System.Linq.Dynamic class im using. public static IQueryable OrderBy(this IQueryable source, string ordering, params object[] values) { if

问题 I'm developing a look-and-feel with two themes. The problem is: I want to be able to switch dynamically between the two themes (it means changing the themes after startup). But the themes have two different sets of icons (in fact the same icons with different colors). I don't know how to change dynamically the icons in the entire application. One solution would be to register each component with an icon and the icon ID on an icon manager to switch between the two kinds of icons, but it seems

问题 I guess this is sort of a philosophical question, but I have some code that dynamically adds templated columns to a GridView by generating the XAML at runtime from Model data and loading it using XamlReader. My question is, In an MVVM world, where should I put the code that accomplishes this? At the moment, I have it in the codebehind, but I'm contemplating whether I should move it to the ViewModel. 回答1: There is a big movement in WPF/Silverlight developers circles to move to a MVVM

问题 I can't delete the dynamically generated arrays. There is how I create them: template <typename T> T **AllocateDynamic2DArray(int nRows, int nCols){ T **dynamicArray; dynamicArray = new T*[nRows]; for( int i = 0 ; i < nRows ; i++ ){ dynamicArray[i] = new T[nCols]; for ( int j=0; j<nCols;j++){ dynamicArray[i][j]= 0; } } return dynamicArray; } And I initialize a 2D array using: long double** h = AllocateDynamic2DArray<long double>(KrylovDim+1,KrylovDim); I can't delete it. Here are the
