Pass an object as a parameter

[secici]

Where can I find online-information(or in the helps) about passing MSForm controls (like Listbox, combobox, etc.) to functions or subs as arguments.

I' ve tried

Sub Trial(ByRef MyCombo As Object)

kind of coding but VBA said to me that I have to declare the class of the object instead of plain "Object". After that I fought with the helps a lot but couldn't find any information about what the classes of these objects are...

Thanks...

Something like this

Sub Trial(ByRef MyCombo As MSForms.Combobox)

should work. I don't know about passing it ByRef, but, that *shouldn't* be a problem.
