Thank you in advance.

Hi all--

Is there a way to add a checkbox (in addition to text) to a column header in a WPF DataGrid? That is, without using DataGridCheckBoxColumn, which would add checkboxes to all grid cells in...

The main class initializes a List<Paragraph> object. New paragraphs are created in a new Task and added to the list of paragraphs. Upon Task completion the paragraph list is scanned in order to...

Thank you for your suggestion, it works. I created an array of 16 dictionaries (~ 2 letters each) and now the application work memory can go above 1 GB.

All right, I chose Dictionary<string, int>. I need to store a lot of data but it's really fast, so performance is not an issue. The problem is, the application crashes with an OutOfMemory exception...

Console.WriteLine() is in the wrong place in your code. Try:


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{

Hm... you either try to imply that it's obvious (which to me it won't be until I run tests with each of the three options) or you just don't know. Either way your answer is not helping.

Given a list of words, I need to determine whether a string perfectly matches a word in the list.

No offense, but I need to understand how things work. If I create a graph in C# and only the entry node is stored in a variable named P then the GC may free at any time the memory used by the entire...

I know, my mistake, I meant "dispose of" (free memory).



That's possible ;)

I appreciate the answers and the link.

As there is no clear method for deleting objects (pointer variables) in C# I wonder how that can be achieved in an efficient manner when working with graphs....

Graphs are the most complex data structures and are typically implemented using pointers. One on the advantages of graphs is that one can programatically add and delete nodes. Apparently, this is not...

Before the C# pros answer your question, please let me make some comments and make some assuptions to see if I understand your question the way you meant it.

Absolutely! And it would be as difficult for me, if I were to write that application, to debug my code. :)
