perl - Why do I get "Pseudo-hashes are deprecated"? -

-

i have code

if (defined($xml->{account}->{p}) == '2') { ... }

which gives me warning

pseudo-hashes deprecated @ a.pl line 48.

the problem in cases $xml->{account}->{p} doesn't exist, why added defined function.

$xml object, if makes difference?

how can fixed, perl doesn't complain?

either $xml or $xml->{account} array, not hash (you can use ref check this, see perldoc -f ref). perl had now-deprecated feature called "pseudo-hashes" allowed special arrays accessed via hash syntax. if care history, can google around or @ older-edition camel book.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
