Reporting Services Line Graph: How to better control the smoothed curve.
I have a report that I built for a client where i need to plot x 0-100, y 0-100. Lets imagine I have these points: 0,0 2,24 50,70 100,100 I need to represent these as a smoothed line chart, as the application of it is a dot gain graph for printing presses. Heres the problem. The line draws fine from 100,100 (top right) down to 2,24. B...
Multiple Constructors with complex logic
In C#, if you have multiple constructors, you can do something like this: public MyClass(Guid inputId, string inputName){ // do something } public MyClass(Guid inputId): this(inputId, "foo") {} The idea is of course code reuse.

Use of the Exception class in c#
Errors that occur deep down in a data access layer or even higher up, (say within ADO.net operations for example) rarely make much sense to an end user. Simply bubbling these errors up to a UI and displaying them will usually achieve nothing except frustration for an end user. I have recently employed a basic technique for reporting err...

VisualStudio using BootCamp/VMWare on OS X
Just bought a 2.4GHz Intel Core 2 Duo iMac with 2GB of memory and a 320GB hard drive. I plan on doing some .net development on it using a BootCamp/VMWare combo since VMWare grants access to the bootcamp partition. What is a recommended size for a BootCamp partition and how much memory should I give VMWare? Any pitfalls to watch out for?...
Logic and its application to Collections.Generic and inheritance
Everything inherits from object. It's the basis of inheritance. Everything can be implicitly cast up the inheritance tree, ie. object me = new Person(); Therefore, following this through to its logical conclusion, a group of People would also be a group of objects: List<Person> people = new List<Person>(); people.Add(me); people.Add(...
C# - Good Books/Tutorials for the advanced .net developer?
I was just reading through the Hidden Features of C# thread, and there were a lot of really neat tricks that I had never even heard of. But there wasn't really a whole lot of depth to them all.

What is the best way to collect/report unexpected errors in .NET Window Applications?
I am looking for a better solution than what we currently have to deal with unexpected production errors, without reinventing the wheel. A larger number of our products are WinForm and WPF applications that are installed at remote sites. Inevitably unexpected errors occur, from NullReferenceExceptions to 'General network errors'.

Prevent .NET from "lifting" local variables
I have the following code: string prefix = "OLD:"; Func<string, string> prependAction = (x => prefix + x); prefix = "NEW:"; Console.WriteLine(prependAction("brownie")); Because the compiler replaces the prefix variable with a closure "NEW:brownie" is printed to the console. Is there an easy way to prevent the compiler from lifting th...
Anyone familiar with a good "sticky windows" library for Winforms?
I want to recreate the stickiness and snapping of windows, like it is implemented in Winamp. The basic premise is, when you drag a window and it comes close to another one, it will snap to it and will stick. When you move it the two will move together. I need it for a MDI application. ...
