Proper way for count empty variables
Date : March 29 2020, 07:55 AM
hop of those help? I use kohana and when you try to fetch data from database it returns class variables(like $user->firstname) as a database data. User table have a 12 columns and i fetch 8 columns but at this point some of columuns maybe empty(like $user->phone). How can i found empty column number ?(Proper way..) , Generically, you could try something like: /**
* Count number of empty data members in a row object.
*/
function countEmpty($row){
$fields = array_keys($row->as_array());
$cnt = 0;
foreach($fields as $f){
if (empty($row->$f)) $cnt++;
}
return $cnt;
}

UIScrollView - setting proper contentOffset for new contentSize yields undesirable empty space

will help you The origin is always (0,0). If you want to insert something above the current offset you'll want to move the current views down by 480 points, add the new view at (0,0) and set the contentOffset to (0,480) (and the contentSize to (320,960).

Linq query: where condition yields an empty sequence even if there should be one match
Date : March 29 2020, 07:55 AM
this one helps. It's not clear from your question but I'm assuming your where-condition is correct but you don't get any result although the source collection does contain an element where the condition should match.
I say should because Control.Tag is an object, and using i.Tag == "DescrOp" will do a comparison by reference instead of by value.

it should still fix some issue Ok so the pb was that due to the collation type instead of SCOTT, the file was encoded with spaces S C O T T. I had to reformat the file in utf8 to fix this!
