these are contents of my text file .. start and end of it .. as you can see it has date in begining followed by time ( just before first comma ) and then few fields (values as numbers ) separated by comma .Now what i want to do is that since .. this file is for specific day and fields are taken after every minute (as you can see the time ) .. i want accumulated values of each hour for one specfic day ( jus like you sumup sixty values for every hour to give one value ) ... like .. VB analyzes contents of each line and based on time it adds corresponding comma separated values ( 0000 to 0059 ) for first hour ... and then for second hour ( 0100 to 0159 ) and so on ... i hope i m making myself clear enuff .. if not lemme know

Regards and thanks in advance
