Assembly: Microsoft.VisualBasic.Compatibility (in microsoft.visualbasic.compatibility.dll)
In Visual Basic 6.0, mouse button parameter mask constants were used to represent the state of mouse buttons in the Button parameter of various mouse event handlers. In Visual Basic Code Name "Orcas", the parameters for mouse events have changed and these constants are no longer necessary. These constants enable code that has been upgraded from Visual Basic 6.0 to continue to run without further modification.
Functions and objects in the Microsoft.VisualBasic.Compatibility.VB6 namespace are provided for use by the tools for upgrading from Visual Basic 6.0 to Visual Basic Code Name "Orcas". In most cases, these functions and objects duplicate functionality that you can find in other namespaces in the .NET Framework. They are necessary only when the Visual Basic 6.0 code model differs significantly from the .NET Framework implementation.
