windows - Collect changing/dynamic variable from batch, and transfer to C# (Visual Studio 2017) -


so writing simple batch program search specified file:

@echo off del temp1.txt del temp2.txt set curfile=0 set percentage=0 set numfiles=0 /f "tokens=*" %%n in ('dir %searchfor% /b /s') set numfiles=%numfiles%+1 /f "tokens=*" %%n in ('dir %searchfor% /b /s') (     set /a "rand=%random% % 10"     set /a "rand=rand*1000"     ping 1.1.1.1 -n 1 -w %rand%> nul     set curfile=%curfile%+1     set percentage=%curfile%*100     set percentage=%percentage%/%numfiles%     set p=%%n if defined p ( echo %p% >>temp1.txt echo %percentage% >>temp2.txt echo %numfiles% >>temp3.txt ))

so not familiar c# @ all, seems intuitive. goal create c# based ui this, can these tasks:

  • run batch script (let's call batch searchr.bat)

  • as batch file searching through files, , updating variables gives these values:

     filepath of file found (defined %%n , %p%)  percentage complete of search through files  total number of files on computer

  • our c# program collect these variables , have access them, , update variables corresponding files update.

so want have c# program running, , batch @ same time, , c# reading outputs of batch file live, update.

i tried keep batch file intuitive possible, there stuff didn't care polish or optimize.

why not in pure batch?

@echo off setlocal enabledelayedexpansion  rem search mask set "searchfor=*.*"  rem needed show progress set/a curfile=0, percentage=0, numfiles=0 /f "tokens=1,2 delims=#" %%a in ('"prompt #$h#$e & echo on & %%b in (1) rem"') set "del=%%a" /l %%i in (1,1,39) set "del_line=!del_line!!del!!del!"  rem file number /f "tokens=*" %%n in ('dir /a-d-s-h /b "%searchfor%" ^| find /v /c ""') set "numfiles=%%n" & echo/processing folder %%~dpn&echo/  ::now work /f "tokens=*" %%n in ('dir /a-d-s-h /b "%searchfor%"') (   set/a curfile+=1, percentage=curfile*100/%numfiles%   <nul set/p=!del_line!processing !curfile! of %numfiles%, !percentage!%%. %%~nxn   rem ...   rem code here   rem ...   ping 1.1.1.1 -n 1 -w 500> nul ) echo/&echo/done.  endlocal exit/b

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
