Как я программно выбираю вкладку на.NET CF TabControl?

Тот же скрипт bash

function sendsms ($m, $to, $n) {
echo "About to sent an sms to $to [$n]\n";

$m = escapeshellarg(addslashes($m)); // use escape for shell
$to = escapeshellarg($to);
// double quotes around command for sub shell
shell_exec('adb shell "am startservice --user 0 -n com.android.shellms/.sendSMS -e contact '.$to.' -e msg '.$m.'"');
}
