query interface in VB??.....

[kunja_chan]

Guyz, I remember working with C++ COM, I could use QueryInterface to find whether an interface is supported in a component. Is there a similar mechanism in VB too? If not what would be a best way to do. :eek:Thnx!

You could use the "IF TYPEOF objectname IS objecttype" statement in VB.NET to determine if a component supports a given interface.

A better method (object orientated etc.) would be to use IsInstanceOf e.g. to find out if MyObject implements the interface IMyInterface use the following code.

GetType(IMyInterface).IsInstanceOfType(MyObject)
