Handle to an object as a parameter

[Pascal_c]

Hello all,

I would like to know if there's a way to pass a handle to an object as a parameter of another function in VB.
Below is an example:

public Function someFunction
Dim objTest as AnObject
set objTest = new AnObject.Something

' ... some code

' Now I will call another function that needs to have
' access to this object, so I pass it as a parameter
AnotherFunction objTest

' ... some more code

End Function

private Function anotherFunction(handleToObject as Variant)
' I can now use that variable as a handle to the
' object instantiated above to call its properties
handleToObject.someProperty

Exit Function
End Function



So, can we do something like that or I'll have to instantiate the object all over again in each function?
Please any help is greatly appreciated.
Thank you all in advance.

The code you gave should work. You just pass along the refference to the object, meaning that you can change properties, call methods, in onther word, the whole stuff.

Cakkie is right... your code should work fine as is, but an improvement would be to type your handleToObject "as AnObject" if it's always going to be the same kind of object (AnObject) or to "as Object" if the object type will vary. This will help the compile find errors as well as allow for early binding, etc.
