Whenever possible, you should use managed code from the. Windows API calls were an important part of Visual Basic programming in the past, but are seldom necessary with Visual Basic. You can use PInvoke in Visual Basic by using either the Declare statement or applying the DllImport attribute to an empty procedure. For more information, see Consuming Unmanaged DLL Functions. Platform invoke is a service that enables managed code to call unmanaged functions implemented in DLLs. NET Framework is performed using platform invoke, or PInvoke.

Because of these differences, and because Windows APIs are not COM objects, interoperability with Windows APIs and the. Windows APIs do not use managed code, do not have built-in type libraries, and use data types that are different than those used with Visual Studio. Windows APIs represent a special category of interoperability. The disadvantage is that Windows APIs can be difficult to work with and unforgiving when things go wrong. The advantage of using Windows APIs in your code is that they can save development time because they contain dozens of useful functions that are already written and waiting to be used. For example, Windows provides a function named FlashWindowEx that lets you make the title bar for an application alternate between light and dark shades. You use them to perform tasks when it is difficult to write equivalent procedures of your own. Windows APIs are dynamic-link libraries (DLLs) that are part of the Windows operating system.
