Opening a .csv file with vbscript that is constantly being updated -

i have .csv file 1 line being overwritten updated data data bus. looks this:

doors closed, open, closed, closed, 

and it's being updated (lets every second) valve changes show in csv file, so:

doors closed, closed, closed, closed, 

if have vbscript reading line of information receive errors trying access said file? here's pretty code have part:

    'create file system object set fso = createobject("scripting.filesystemobject")  'initialize few items strsource = "c:\test.csv"  'open source file read set inputfile = fso.opentextfile(strsource,forreading)  'skip first line since heading strline = inputfile.readline  'read file line line while not inputfile.atendofstream     strline = inputfile.readline      'split line on comma array     strvalues = split(strline, ",") 

the code works .csv files aren't in use wondering if throw errors (even though i'm reading it) if file accessing being updated.

thanks
