c# - Relative Paths of File.Open() in a DLL -


i'm working on solidworks plugin (dll). depends on couple of files (sqlite db, sketches etc). install plugin, have open dll solidworks.

in dll routines call file.open() on number of resource files i'll refer relative paths. dir. hierarchy like:

plugin/     plugin.dll     sketches/         various.sldprt     otherfile.db     otherdeps.txt     ...

where root dir. of plugin can anywhere on system. plugin can loaded solidworks open file dialog. problem once load dll, calls file.open() (eg file.open("sketches/various.sldprt")) relative paths won't work because it'll relative dir. sldworks.exe (sw install dir.) resides instead of dir. of dll. mean i'll have put resource files in solidworks install dir., avoid. possible?

what can add addin folder prefix local path before calling file.open(). addin folder can obtained :

string path = system.io.path.getdirectoryname(        system.reflection.assembly.getexecutingassembly().getname().codebase );

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() .
