Anytime I invoke a method on a COM object with one or more arguments,
I get the following error:
Could not convert argument 0 for call to Open. (ArgumentError)
What's preplexing is the argument number is always the last argument,
so if there are four arguments, the error will be on argument 3. Here
is an example script that gives the error above:
def new_com_object(prog_id)
System::Activator.CreateInstance(System::Type.GetTypeFromProgID(prog_id))
end
xls = new_com_object('Excel.Application')
xls.Visible = true
xls.Workbooks.Open('c:\\Book1.xls')
