windows - Delete all but one file loop with bat script -


i have loop in batch file delete 1 file in directory (windows 7). hangs because still sends commands screen, though i'd thought i'd suppressed it. here command i'm using:

for %i in (*) if not %i == update.bat del /s %i >nul 2>&1

tested batch script, log shows stops right @ command. tested command @ command line, outputs "del /s file.ext >nul 2>&1" command prompt each file in directory, causes batch file hang.

what need change here?

if directly in open cmd window , not batch,
can suppres output of current command leading @ sign.

@for %i in (*) @if /i not "%i"=="update.bat" @del "%i" >nul 2>&1

in batch toggle output of commands @echo off , double % signs of variable.

@echo off %%i in (*) if /i not "%%i"=="%~nx0" del "%%i" >nul 2>&1

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
