function for converting DMS format to Decimal in Microsoft Excel Visual Basic -


i have problems using visual basic in ms. excel. have sort of coordinates data in dms format (longitude , latitude) it's not in usual format. data seems this:

 e 103 29 12.4562   w 3 9 1.4562   n 16 5 32.4333   s 16 5 2.4333

i want convert standard decimal format. however, i've never used visual basic before. convention e, n , w, s 1 , -1, respectively. expecting output data list 

 103.4867934  -3.1504045  16.09234258  -16.08400925

i hope can make visual basic code convert data because have lots of data , can't convert manually.

thanks.

instead of vba can use formula:

=--(index({"+","+","-","-"},match(left(a1,1),{"e","n","w","s"},0))&mid(a1,3,find(" ",mid(a1,3,len(a1))))+mid(a1,find("}}}",substitute(a1," ","}}}",2))+1,2)/60+mid(a1,find("}}}",substitute(a1," ","}}}",3))+1,99)/3600)

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() .
