o launch the API, use the 'Run' API of the VisioAddon component. Two
parameters must be supplied to the 'Run' API:
/CMD=400 - Visio UML Solution recognizes the 400 command as the XMI export
function;
/XMIFILE="yourfilename" - This parameter specifies the file where the XMI output will
be written. The file name must be double-quotes delimited.
(No blanks are allowed between the '=' and the
file name. The file is created if it does not
exist. An existing file will be overwritten.)
