How to raise events defined in the Implements Class

[BhanotAbhilash]

I am defining a common interface for various classes (polymorphism) using Implements clause. I have written a class to declare the interface (IClass). In all the other classes I put in an Implements clause to Implement the interface defined by IClass. I want to raise events defined in IClass, but the RaiseEvent function does not list or accept the events of IClass as parameters.

How can I raise the events defined by IClass.

I could be wrong on this, but I beleive that VB does not consider events as part of an interface. I'm currently doing the same thing and I'm having to redeclare the events in each control that is Implmenting my common Interface. It sux, but I'm pretty sure that's the way COM defines it. Interfaces have properties and methods. Events are part of an interface.

I found this to be true as well, I thought that I could overcome the problem by creating an interface that has functions to replace the events. The program that would normally respond to the events would create a class that implements the interface. I thought that I could create an instance of the class and pass it to the class that was raising the events using a formal parameter or a property. That way the class or process that was raising events would call functions in the passed object to replace the functionality of the events.

My problem is that my activeX exe that was responding to events raised in another activex dll will not allow the external interface to be implelmented. The interface does not show up in the class.

What I mean is that you normally see three items in the left-hand drop down box of a class that implements an interface.


option Explicit
Implements MTInterface.cMTExtIfc

'Some functions




I would normally see the following items in the drop down list.
(General)
Class
cMTExtIfc

VB is not adding item three and I do not understand why. MTInterface is an external activex dll that contains my exposed interfaces

Please provide any insight.

This is the contents of the interface

option Explicit

public Sub ResultsKey(psResultID, psResultFileName, psFullPath)
End Sub
public Sub NoResults()
End Sub
public Sub ResultIDnotFound()
End Sub
public Sub ResultFileEOF()
End Sub
public Sub SetAssayVisible(pVisible as Boolean)
End Sub
public Sub SetWellVisible(pVisible as Boolean)
End Sub
public Sub SetAbsorbVisible(pVisible as Boolean)
End Sub
public Sub SetVesselVisible(pVisible as Boolean)
End Sub
public Sub UpdateResultsProgress(pValue as Integer)
End Sub

End Sub

End Sub

End Sub
