Assembly: Microsoft.VisualBasic.Compatibility (in microsoft.visualbasic.compatibility.dll)
In Visual Basic Code Name "Orcas", the Visual Basic ZOrder method is replaced by the BringToFront and SendToBack functions. These constants enable code that has been upgraded from Visual Basic 6.0 to continue to run without additional 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.
