' CopyModule
' This function copies a module from one VBProject to
' another. It returns True if successful or False
' if an error occurs.
'
' Parameters:
' --------------------------------
' FromVBProject The VBProject that contains the module
' to be copied.
'
' ToVBProject The VBProject into which the module is
' to be copied.
'
' ModuleName The name of the module to copy.
'
' OverwriteExisting If True, the VBComponent named ModuleName
' in ToVBProject will be removed before
' importing the module. If False and
' a VBComponent named ModuleName exists
' in ToVBProject, the code will return
' False.
