Namespace: Microsoft.VisualBasic.Compatibility.VB6
Assembly: Microsoft.VisualBasic.Compatibility.Data (in

public ref class ADODC : public UserControl, DataSource
public class ADODC extends UserControl implements DataSource
public class ADODC extends UserControl implements DataSource
Not applicable.

Use this control in applications upgraded from Visual Basic 6.0 to continue to use an ADO data connection. For new development, you should consider using ADO.NET instead of ADO. For more information, see Comparison of ADO.NET and ADO.


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.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
