i want to create a DLL where i can pass parameters etc. this thing works when i do it through a class module.. i mean something like .. hmm..

Sub DisplayInCombo (vbComboBox as ComboBox)
vbComboBox.AddItem "Hello"
End Sub

when i do the above, through a class it works. but while compiling the DLL, it gives me an error.
Can someone please help?
