i running below powershell command getting error:trying calculate sizes of folder , files in each drive if size lessthan 1kb print size in kb otherwise in mb or gb 

ls -force | add-member -force -passthru -type scriptproperty -name length -value {ls $this -recurse -force | measure -sum length | select -expand sum } | sort-object length -descending | format-table @{label="totalsize (mb)";if ($_.length -lt 1kb)  {expression={[math]::truncate($_.length / 1kb)};width=14}  else {expression={[math]::truncate($_.length / 1gb)};width=14}}, @{label="mode";expression={$_.mode};width=8}, name

error

    missing '=' operator after key in hash literal.     @ line:1 char:230     + ls -force | add-member -force -passthru -type scriptproperty -name      length -value {ls $this -recurse -force | measure     sum length | select -expand sum } | sort-object length -descending |             format-table @{label="totalsize (mb)";if ( <<<< $      _.length -lt 1kb) {expression={[math]::truncate($_.length /      1kb)};width=14} else {expression={[math]::truncate($_.lengt     h / 1gb)};width=14}}, @{label="mode";expression={$_.mode};width=8},      name     + categoryinfo          : parsererror: (:) [],      parentcontainserrorrecordexception     + fullyqualifiederrorid : missingequalsinhashliteral

as error message hints at, can't place value expression directly inside hashtable literal.

move condition inside expression scriptblock:

@{     label="totalsize (mb)"     expression={         if($_.length -lt 1kb){             [math]::truncate($_.length / 1kb)         }         else{             [math]::truncate($_.length / 1gb)         }     }     width=14 }

although think should remove (mb) part of label in case, since you're not showing size in mb.

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
