how can set macro strip letters #####xx in column , put them in column l same row? thanks! assuming you're working first sheet , you're stripping off last 2 characters while leaving first 5 characters, following code work: public sub stripoff() dim irow integer irow = 2 'assuming row 1 headers, else make 1 while sheets(1).range("i" + cstr(irow)).value <> "" sheets(1).range("l" + cstr(irow)).value = right(sheets(1).range("i" + cstr(irow)).value, 2) sheets(1).range("i" + cstr(irow)).value = left(sheets(1).range("i" + cstr(irow)).value, 5) irow = irow + 1 wend end sub

what best practice simulate clause? realize considered related (though don't think it's duplicate) of this question . however, in case want handle exceptions, want use (or whatever php equivalent or practice) defined python: a clause executed before leaving try statement, whether exception has occurred or not. just loosely writing code after try-catch block seems ugly practice me. in rfc adding php , suggest workaround: <?php $db = mysqli_connect(); try { call_some_function($db); } catch (exception $e) { mysqli_close($db); throw $e; } mysql_close($db); so unless upgrade php 5.5 (which contain finally construct), best option.

this question has answer here: is java “pass-by-reference” or “pass-by-value”? 74 answers i understand passed reference in java. why doesn't work in case? had thought should print out "hate" instead of "love". class test { static class str { public string str; public void set(string str) { this.str = str; } } public static void main(string[] args) { str s = new str(); string str = "love"; s.set(str); str = "hate"; system.out.println(s.str); } } in main function, str stores reference string. when doing str = "hate" , reference changes original object "love" has been stored in s.str , remains there. see this more clarification.
