Lookup function in VB6 -

-

i have table in excel file called " employee_states_file".this table contains 2 columns name , states. both columns filled data. province table contains abbreviation of states such " ne, wa" , so. have excel file called " states_file" contains table has 2 columns: abbreviation , fullstatename. table considered lookup table full state names based on abbreviation. now, want write code in vb6 when user click button, abbreviation names in table of excel file " employee_states" changes full state names based on lookup table of excel sheet " states_file". make sense? please help,

if allowed convert them csv files (comma delimited text files) can use jet database engine , normal sql joins.

i use setup connection.

public function opentextconnection(byval filename string) connection     dim fso filesystemobject     dim dbfolder string     dim ts textstream      set fso = new filesystemobject     dbfolder = fso.getparentfoldername(filename)      if fso.fileexists(fso.buildpath(dbfolder, "schema.ini"))         fso.deletefile (fso.buildpath(dbfolder, "schema.ini"))     end if      set ts = fso.createtextfile(fso.buildpath(dbfolder, "schema.ini"))     ts.writeline "[" & fso.getfilename(filename) & "]"     ts.writeline "format=csvdelimited"     ts.writeline "colnameheader = true"     ts.writeline "maxscanrows = 0"     ts.close      set opentextconnection = new connection       if fso.folderexists(dbfolder)         opentextconnection.open "provider=microsoft.jet.oledb.4.0;data source=" & dbfolder & ";extended properties=""text;hdr=yes;fmt=delimited;"";"     else         msgbox dbfolder & " not exists.", vbexclamation     end if  end function

each file table in connection , can sql joins. note example open table. can use valid sql syntax.

dim db1 connection dim tb recordset dim fso filesystemobject dim timport new dbimportlist set fso = new filesystemobject set timport = new dbimportlist if fso.fileexists(filename)     set db1 = opentextconnection(filename)     set tb = new recordset      tb.open "select * [" & fso.getfile(filename).name & "]", db1, adopenkeyset, adlockoptimistic, adcmdtext  end if
