Public OpenProjectPath As String
Public OpenByArgs As String

Public Sub Main()

  Dim sArgsString As String
  Args.Begin(Application.Name & " <options>")
  Args.End()
  For Each sArgsString In Args.End()
    If Not IsNull(sArgsString) Then
      OpenProjectPath = sArgsString
      OpenByArgs = True
    Endif
  Next
  FMain.Show

End

That is how I did it thanks to the hint of Fabien.
