I'm currently working on an access control program in C# and I've come across the problem of blocking windows. The original idea I've come up with is rendering a plain black form over the position given by the IntPtr window handle of the process. The problem within that is updating the form's position smoothly and z-index of the position...

I feel like I'm missing something obvious here, but I don't see it written anywhere. I sign my executables using an Authenticode certificate, but as I've started to learn a bit more about it, I am questioning the value as-is. A signed exe has a digital certificate that shows as being a "valid" certificate. When you download such a fi...

Is it better to declare a variable used in a loop outside of the loop rather then inside? Sometimes I see examples where a variable is declared inside the loop. Does this effectively cause the program to allocate memory for a new variable each time the loop runs? Or is .NET smart enough to know that it's really the same variable. For ex...

I want to not only use these assemblies, but somehow put a Silverlig...

I've had an idea for some time now to write a trading platform application similar to think or swim in Silverlight. First of all is it something that one person can do in a reasonable time-frame? Ok next question is how would the performance of the Silverlight be running such a memory intensive application? Will it scale? Nearly all t...

Since F# 2.0 has become a part of VS2010 I take an interest in F#. I wondered what's the point of using it. I'd read a bit and I made a benchmark to measure functions calling. I have used Ackermann's function :) C# sealed class Program { public static int ackermann(int m, int n) { if (m == 0) return n + 1; ...
