Windows Runtime IntegrationAnders shows that the new Windows Runtime has been deeply integrated. NET and C #, for example, using C # as the "Compute engine" and then outputting the HTML/JavaScript Metro App (just like C ++ ). So you can create a C # project, compile it into a WinMD

order to achieve functional expansion. This means that you have the ability to invoke dynamic connection libraries. Visual C #, like other development tools, can also invoke the API functions of a dynamic-link library. NET Framework itself provides a service that allows the governed code to invoke the unmanaged functions implemented in the dynamic-link library, including the Windows API functions provided by the operating system. It is able to locate

Beginner vb.net, sum up ByVal and ByRef 1 pass through the ByVal variables, VB. NET duplicates a new variable that is equal to the source value. And ByRef is the equivalent of a reference. For example, when we learn C, we get the swap () function Imports System ' Test that Can ' t Swap A and B Class MyApp Public Shared Sub Main () Dim A as Integer = 0 Dim B as Integer = 1 Console.WriteLine ("Source:a" A

There are bugs in the original, because this is the code I converted from C #, where the original conversion was not fully compatible because of the different nature of the two languages. Of course, now I am fully capable of compatible with the characteristics of both languages, so rewrite this code, the original code in the event detection, as well as the original code in the KeyPress time can not detect input character casing bug elimination (thanks to Comrade Verywzm).
