You have several options to call a method with Jabaco. I'll explain the differents.

The fastest method is calling a known object:

	Jabaco Source
1 2 3 4	'1) Create a "Known Object": Dim mySocket As New VB#Winsock mySocket.Connect "127.0.0.1", 1234 MsgBox mySocket.RemoteHost

Using the Variant-Type to call a method. Internal it will use reflections so it is slightly slow:

	Jabaco Source
1 2 3 4	'2) Assign the Object to Variant: Dim myVariant As Variant = mySocket myVariant.Connect "127.0.0.1", 1234 MsgBox mySocket.RemoteHost

Same like the Variant-Method, but little verbosely:

	Jabaco Source
1 2 3 4 5	'3) Using the CallByName-Method: Dim myArgs(1) As String myArgs(0) = "127.0.0.1" myArgs(1) = 1234 CallByName mySocket, "Connect", VBMethod, ""

This is the background of 'CallByName'. More verbosely, but also more powerfull:

	Jabaco Source
1 2	'4) Java Reflections: 'See: http://java.sun.com/docs/books/tutorial/reflect
