I want to know the number of visitors online on my site. I did my research and found two solutions. Source: Code Project Online active users counter in ASP.NET It is easy to setup and easy to use but it increases the user count for every Ajax request/response too. My home page alone has 12 Ajax requests(8 requests to one page and 4 requests to another page). This dramatically increases the user count.

I'm developing a console application that is supposed to run under WinCE 6.0 and WinCE 7.0 . I'm using C# , Compact Framework 2.0 for different compatibility reasons. My application is started by an external runtime called TwinCAT (from Beckhoff). Within this application, my teammate used a function block called nt_startProcess (documentation here ) that is in charge of starting my application on demand. My problem - Two different behaviors depending on the OS : When started manually (without TwinCAT) from a cmd line : My application behaves properly on both systems. It means that, the

I have a class with 2 strings and 1 double (amount). class Donator string name string comment double amount Now I have a Array of Donators filled. How I can sort by Amount? If you implement IComparable<Donator> You can do it like this: public class Donator :IComparable<Donator> { public string name { get; set; } public string comment { get; set; } public double amount { get; set; } public int CompareTo(Donator other) { return amount.CompareTo(other.amount); } } You can then call sort on whatever you want, say: var donors = new List<Donator>(); //add donors donors.Sort(); The .Sort() calls the
