Description

In some development environments it is not possible to query interface directly on the control to other COM interfaces, beacuse the control is contained within a wrapper object. To get the real control use the Object property.

[C#]

When querying interface to IMapControl2, IMapControl3, IMapControl4 or IMapControlDefault  in Visual Basic .NET or Visual C# .NET the Object property or container specific code must be used. This is because .NET contains the real control inside a wrapper object known as an host.

IMapControl3 mapControl = axMapControl1.Object as IMapControl3;

[Visual Basic .NET]

When querying interface to IMapControl2, IMapControl3, IMapControl4 or IMapControlDefault  in Visual Basic .NET or Visual C# .NET the Object property or container specific code must be used. This is because .NET contains the real control inside a wrapper object known as an host.

Dim mapControl As IMapControl3 = AxMapControl1.Object
