I generally prefer IEnumerable<T> as well. The main thing is to ask yourself what actual (even minimum) functionality is being returned from the method (or passed to it, in the case of a method argument). If all you need to do is enumerate over a result set, then IEnumerable<T> does exactly that. No more, no … Read more
Before calling LogManager.GetLogger(“”) You have to call log4net.Config.XmlConfigurator.Configure(); In an ASP.NET app you probably want to put this call in Application_Start
Others have addressed the “why?”. It is easy however to roll your own Add(ref double, double), using the CompareExchange primitive: public static double Add(ref double location1, double value) { double newCurrentValue = location1; // non-volatile read, so may be stale while (true) { double currentValue = newCurrentValue; double newValue = currentValue + value; newCurrentValue = … Read more
List(Of String) will handle that, mostly – though you need to either use AddRange to add a collection of items, or Add to add one at a time: lstOfString.Add(String1) lstOfString.Add(String2) lstOfString.Add(String3) lstOfString.Add(String4) If you’re adding known values, as you show, a good option is to use something like: Dim inputs() As String = { “some … Read more
In the KeyDown Event: If e.KeyCode = Keys.Enter Then Messagebox.Show(“Enter key pressed”) end if
The | operator has a high precedence and in your original regex will get applied first. You should be combining the two regex’s w/ grouping parentheses to make the precedence clear. As in: “^(([A-Z]\d{8})|(\d{9}))$”

As section 2.2 of The OAuth 2.0 Authorization Framework says: The authorization server issues the registered client a client identifier — a unique string representing the registration information provided by the client. The client identifier is not a secret; it is exposed to the resource owner and MUST NOT be used alone for client authentication. … Read more
It is weird, but it works: string url = @”http://example.com/file.jpg”; string ext = System.IO.Path.GetExtension(url); MessageBox.Show(this, ext); but as crono remarked below, it will not work with parameters: string url = @”http://example.com/file.jpg?par=x”; string ext = System.IO.Path.GetExtension(url); MessageBox.Show(this, ext); result: “.jpg?par=x”
A VB.NET module is a static class. The compiler handles this for you. Every method and property on it is static (Shared). A class with a static (Shared) member on it is exactly that: a class with a static (Shared) member. You don’t have to create an instance of it to access the static (Shared) … Read more
