You can see the list of available parameters by "-H" command line switch.
For the sample file, try "-F ..\..\sample.vrp -N 5 -u 522".

Here are the steps you need to follow:
-add the directory of the header files of GLPK (should be
"your_glpk_root\include") to the additional include directories sections of
both "libSymphony" and "symphony" projects(through each project's properties
menu)
-add USE_GLPMPL to the preprocessor definitions sections of both projects
-add the GLPK library to the solution and have the startup project
"symphony" depend on this library (from the project dependencies menu)

Let me know how it goes.
