I'm fairly new to WPF and I've come across a problem that seems a bit tricky to solve. Basically I want a 4x4 grid thats scalable but keeps a square (or any other arbitrary) aspect ratio. This actually seems quite tricky to do, which surprises me because I would imagine its a reasonably common requirement.
I start with a Grid definiti...
I have a requirement to extract a distinct subset of rows from a DataTable, and thought LINQ2DataSets may be a useful and clean way to do this, however it appears that it is not possible to simply identify return rows from a LINQ2DS query as follows

r.Field<string>("FACILITY_PROCESS_SUB_...

Similar to this question, but in 2.0, we want to sort by one element, then another. we want to achieve the functional equivalent of SELECT * from Table ORDER BY x, y
We have a class that contains a number of sorting functions, and we have no issues sorting by one element.
For example:
public class MyClass {
public int x;...
Is there a better free TreeView control that exists for Visual Studio 2008 / .NET 3.5?
I believe I need something a little more powerful than the out-of-the box version. I'm not exactly sure for what yet but I thought I'd ask quickly before I get too far in to my project...
Thank you!

Say I have two lists:
var list1 = new int[] {1, 2, 3};
var list2 = new string[] {"a", "b", "c"};

new {i = 1, s = "a"},
new {i = 1, s = "b"},
new {i = 1, s = "c"},
new {i = 2, s = "a"},
new {i = 2, s = "b"},

I use the app.config file to store some values (path to a mapping database, data connection selections). These settings differ on the user machines and I would like the installer to set them right.

Given the following class:
class TestClass {
public void SetValue(int value) { Value = value; }
public int Value { get; set; }

I can do
TestClass tc = new TestClass();
Action<int> setAction = tc.SetValue;
setAction.Invoke(12);
which is all good. Is it possible to do the same thing using the property instead of the method? P...
I distribute my application using a VS2008 install package, which normally works great. When I create new versions of the app, I go in and increment the Version property on the install package and verify the RemovePreviousVersions property is set to True.
This works just fine most of the time - I just run the install package for the ne...

What are the things to consider when choosing between ByRef and ByVal.
I understand the difference between the two but I don't fully understand if ByRef saves resources or if we even need to worry about that in the .Net environment.
How do you decide between the two if the functionality doesn't matter in a situation?
