Assuming you have a variable in your VB6 program that references
the Excel Application, you can use the Run method to execute the
sub. E.g,.

XLApp.Run "workbookname.xls!Sub_1", "Msg"

Hello There,

How do I execute, say the Excel Public Sub Sub_1(msg as
string), subroutine
from a Visual Basic 6.0 Program?

Thanks,
Ivan
