Ok I found it: just use -- and argument. Now I have an other problem, an authorization one... The matter is coming from this .pvx, whan I open it I get: [Config] debug=0 ButtonCursor=0 Icon=c:\Vgcs\pvx\Lib\_Bmp\Vg\Optimsvg.ico CommandLine=-mn *ntslave -arg 10.100.102.34 vg [WindowFrame] TypeSizeLoc=2,663,501,137,69 [Font] Points=12 Charset=0 Name=Fixedsys LockFont=1 TipFontName=Tahoma TipFontPoints=10 SystemFontName=Tahoma SystemFontPoints=12 [vg.launch] debugmode=0 Startprogram=axmenu visualenv=d:\vg\Visualdata\Sysf\ [vg.Program] ShowMenuDesc=1 ShowOptId=1 ShowFnKeys=1 I think I have to change one of the Windows network adress like: "d:\vg\Visualdata\Sysf\" to a Linux based one...but it is a Win 2003 server so I don't know how to do that...
