Interaction Class

The Interaction module contains procedures used to interact with objects, applications, and systems.

Namespace:  Microsoft.VisualBasic
Assembly:  Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)
public final class Interaction

For more detailed information, see the Visual Basic topic Interaction Module (Visual Basic).

This module supports the Visual Basic language keywords and run-time library members that run other programs, call a method or property, sound a beep from the computer, provide a command-line string, manipulate COM objects, and control dialog boxes.

The following example uses the Shell function to run an application specified by the user. Specifying AppWinStyle.NormalFocus as the second argument opens the application in normal size and gives it the focus.

Dim procID As Integer
' Run calculator.
procID = Shell("C:\Windows\system32\calc.exe", AppWinStyle.NormalFocus)
' The preceding path is for Windows XP.
' The Windows 2000 path is C:\WINNT\system32\calc.exe.
System.Object
  Microsoft.VisualBasic.Interaction
