i able receive first line , have added list box. in mainwindow class have declared 2 list of string store column , rows.

try this....

imports system.data.oledb  public class form1  private sub form1_load(sender object, e eventargs) handles mybase.load     dim folder = "path csv folder (do not include file name here)"     dim cnstr = "provider=microsoft.jet.oledb.4.0;data source=" & folder & ";extended properties=""text;hdr=no;fmt=delimited"";"     dim dt new datatable     ' change test.csv csv file name here     using adp new oledbdataadapter("select * [test.csv]", cnstr)         try             adp.fill(dt)         catch ex exception         end try     end using      datagridview1.datasource = dt end sub  end class

this import csv file display straight datagridview control (list box has problem columns)... hope helps

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
