c# - Visual Studio development server unexpectedly executes Thread.Abort -


the following code results in our visual studio 2012 development web server, or alternative iisexpress, killing appdomain of our webapp executing thread.abort in of it's constituent threads threadpool. not understand why? cannot find documented states under circumstances web server this. also, there precious little "verbose" output of web server itself.

this took several days worth of effort track down. normal debugging techniques proved worthless. had resort tried , tested method of commenting out method bodies until reached "ah-ha" moment.

one of our developers had inadvertently created temporary file , closed again deep within 1 of our asp.net services.

filestream fs = file.create(strfilepath); | fs.close;

the strfilepath accidentally set same location webapp's assembly location. namely:

var basepathuri = new uri(assembly.getexecutingassembly().codebase); var strfilepath = path.getdirectoryname(uri.unescapedatastring(basepathuri.absolutepath));

it's worth saying, error corrected correctly writing system temporary file space.

so once, again, know bad practice, why visual studio web server behave does?

ps know there deployment difference between development web server , production web server (e.g. apache or nginx) regard copying content temporary asp.net location. in fact, problem not manifest in deployment.

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...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

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() .
