c# - How to execute SMART Self-Test -


i writing application based on .net checks heath of disk or more disks in system.

i can use wmi interface atapi @ smart data, followed link: http://wutils.com/wmi/root/wmi/msstoragedriver_atapismartdata/

but don't know how execute smart self-test. there ways using c#?

i trying same , found out possible start test via wmi. have @ wmi class msstoragedriver_failurepredictfunction under root\wmi namespace. class has several different methods can use. 1 of them executeselftest method. @ example created wmi code creator(wmicodecreator)

            try             {                 managementobject classinstance =                      new managementobject("root\\wmi",                      "msstoragedriver_failurepredictfunction.instancename='scsi\disk&ven_hitachi&prod_hds721010cla632\4&7d4adf0&0&010000_0'",                     null);                  // obtain in-parameters method                 managementbaseobject inparams =                      classinstance.getmethodparameters("executeselftest");                  // add input parameters.                 inparams["subcommand"] =  1;                  // execute method , obtain return values.                 managementbaseobject outparams =                      classinstance.invokemethod("executeselftest", inparams, null);                  // list outparams                 console.writeline("out parameters:");                 console.writeline("returncode: " + outparams["returncode"]);             }             catch(managementexception err)             {                 messagebox.show("an error occurred while trying execute wmi method: " + err.message);             }

you have change instancename in code above diskname. found out "subcommand" parameter factor determines test start. if value 1 start short self-test. if value 2 start extended self-test.

as output parameter can receive 1 of 3 values ['0', '1', '2'] while 0 stands 'successful completion' , 1 stands 'captive mode required' , 2 stands 'unsuccessful completion'. source(failurepredictfunction)

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() .
