notepad++ - Regex replace one value between comma separated values -


i'm having bunch of comma separated csv files. replace exact 1 value between third , fourth comma. love notepad++ 'find in files' , replace functionality use regex.

each line in files this:

03/11/2016,07:44:09,327575757,1,5434543,...

the value replace in each line number 1 one.

it can't simple regex e.g. ,1, somewhere else in line, must 1 after third , before fourth comma...

could me regex? in advance!

two more rows example:

01/25/2016,15:22:55,276575950,1,103116561,10.111.0.111,ngd.itemversions,0.401,0.058,w10,0.052,143783065,,... 01/25/2016,15:23:07,276581704,1,126731239,10.111.0.111,ll.browse,7.133,1.589,w272,3.191,113273232,,...

you can use

^(?:[^,\n]*,){2}[^,\n]*\k,1,

replace value need.

the pattern explanation:

  • ^ - start of line
  • (?:[^,\n]*,){2} - 2 sequences of
    • [^,\n]* - 0 or more characters other , , \n (matched negated character class [^,\n]) followed with
    • , - literal comma
  • [^,\n]* - 0 or more characters other , , \n
  • \k - operator forces regex engine discard whole text matched far regex pattern
  • ,1, - in match.

note \n inside negated character classes prevent overflowing next lines in document.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
