javascript - Use Module.HEAP8.set Get messed data -


i use emscripten compile c code asm.js c code this:

 int _call_main(char* p, int number)//p start arrary, number lengh

i want send bytearray data c code, js code this:

var decode_encode_audio = module.cwrap('_call_main', 'number', ['array','number']); ........ var bytearray = new uint8array(message.data);//audio data var offset = module._malloc(70000); module.heap8.set(bytearray, offset); decode_encode_audio(offset , bytearray.length);

in c code, print point p array, got messed data, start part , end part of p correct(i save file), however, in middle part messed.i replace function(module.heap8.set) [module.heapu8.set],also got error. don't know why?

i change js code :

var decode_encode_audio = module.cwrap('_call_main', 'number', ['number','number']);//not array ........ var bytearray = new uint8array(message.data);//audio data //var offset = module._malloc(70000); //module.heap8.set(bytearray, offset); decode_encode_audio(bytearray, bytearray.length);

i got correct data.

can tell me what's wrong "module.heap8.set" method.

you writing unsigned data uint8array signed view heap8. should use heapu8, used unsigned data.

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() .
