.net - JSON.NET date with space in timezone offset -


i have odd issue vb.net program (vs2012 / .net framework 4) uses json.net (newtonsoft) v4.0.8 serialise objects. there dates amongst properties of class i'm serialising, , date serialised include timezone offset of +0000 or +0100 expect. however, on customer's computer plus being serialised space, , on being deserialised later (having been in database, in same vb.net program using same json.net dll), deserialise method throws exception saying string isn't in correct format (and can see it's when it's trying parse number @ heart of json.net dll).

an example of date see on computer , on customers' computers is:

"/date(1455017231091+0000)/"

whereas 1 customer (and possibly others, judging number of times i've seen resultant exception) comes out this:

"/date(1455017231091 0000)/"

i'm not sure how can reliably deal (probably regex looks appropriate number of digits followed space , 4 digits) first of want find out if normal , whether can stop happening using setting on date serialiser.

note since has been in production know json.net has switched default iso8601 date format, considering using, need convert existing dates stored in database first.

the code using serialise looks this:

stringstoredindatabase = jsonconvert.serializeobject(instanceoft)

and code deserialise looks this:

jsonconvert.deserializeobject(of t)(stringstoredindatabase)

any advice appreciated.

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...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

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() .
