I have a couple of compiled, registered Java classes that I am using as COM objects in VB.

I am able to load and use various methods of my classes to set and retrieve data but am having problems with one in particular.

I want to pass one of the classes to the other as a method argument:

e.g:

Dim objDataClass As DataClass.DataClass
Set objDataClass = CreateObject("DataClass")

Dim objDoCalc As DoCalc.DoCalc
Set objDoCalc = CreateObject("DoCalc")

Dim iNumber1 As Integer
iNumber1 = 5

' ** This method works fine
objDataClass.setNumber (iNumber1)

' ** This doesn't work
objDoCalc.SetData (objDataClass)

At this point I receive a 'Run-time error 424: Object required' error message.

Why can't I pass one class to another? I notice that VB changes the method name from 'setData' to 'SetData' when I attempt to pass in my own object.

Is it possible to do this? Where am I going wrong?

Many thanks,

Maeve
