Remarks

Note

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 2008. 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.

Methods

GetColumnInfo(Int32, IntPtr, IntPtr)

Returns the column metadata needed by most consumers.
MapColumnIDs(Int32, DBID[], Int32[])

Returns an array of ordinals of the columns in a rowset that are identified by the specified column IDs.
