Try to project your point on this curve (Geom2dAPI_ProjectPointOnCurve),then use function "Parameter" this will give you the parametric value of your vertex. (please read the documentation to get the exact way to do it)
Good Luck

Hello Jack,
try using
Standard_Real t=BRep_Tool::Parameter(vertex,edge);
Good Luck,
Francois.
