when getstring of database: inf = c.getstring(5); //inf equals "hello how you?\nfine , you\ni fine, thanks."; when print appears in same way , not execute parameters "\ n": tv1.settext(inf); //the text "is hello how you?\nfine , you\ni fine, thanks." but want: "hello how you? fine , fine, thanks." what problem? the solution me: string finalinf = inf.replace("\\n", system.getproperty("line.separator")); tv1.settext(finalinf); thanks : skaard-solo , rest. i think can try string finalinf = inf.replace("\\n", system.getproperty("line.separator")); tv1.settext(finalinf); system.getproperty("line.separator")) is system replacement new line

Php file image upload security -

$filename=$_files['file']['name']; $type=$_files['file']['type']; $extension=strtolower(substr($filename, strpos($filename, '.')+1)); $size=$_files['file']['size']; if(($extension=='jpg' || $extension=='jpeg') && ($type!='image/jpg' || $type!='image/jpeg')){... i have input file, can let user upload jpg/jpeg image only, have check type, extension, size. however i'm not sure how check if user change extension.(ex. abc.php -> abc.jpg) any thing else need check before save user's image server? you can check image exif_imagetype() http://www.php.net/manual/en/function.exif-imagetype.php exif_imagetype() reads first bytes of image , checks signature.

python - tk: do I need to mention the widget master? -

i want rearrange frames in panedwindows @ runtime based upon user request. specified master each frame (here pw1). ex: import tkinter tk root = tk.tk() pw1 = tk.panedwindow(orient=tk.horizontal, sashpad=2, sashwidth=4, sashrelief=tk.raised) pw1.pack(fill=tk.both, expand=1) frame1 = tk.frame(pw1, bg='red',width=100, height=100) frame2 = tk.frame(pw1, bg ='yellow',width=100,height=100) # seems same thing: # frame1 = tk.frame(bg='red',width=100, height=100) # vs. tk.frame() # frame2 = tk.frame(bg ='yellow',width=100,height=100) pw1.add(frame1, sticky=tk.nsew) pw1.add(frame2, sticky=tk.nsew) root.mainloop() what advantage of specifying master? the master paremeter can interpreted parent . passing add new key in parent.children attribute. if print pw1.children when not pass master and not execute pw1.add() see returns empty dictionary. print pw1.children #{} the pw1.add() method includes added widget in pw1.children

in pascal, way dared cleaning array iterate through , clear it, extremely inefficient. can't reinitialize assigning empty array it? program arrays; var working, empty : array [1..10] of integer; begin working[3] := 5; working:= empty; end. is ok this, can backfire? this absolutely fine. semantics of code need. delphi compiler emit code perform simple , efficient memory copy. compiler able because have fixed length array elements simple value types. i'd surprised if fpc did not produce similar code. even if array contained managed types (it doesn't), assignment operator result in code respected managed types. as final comment, array full of zeros should constant.

lisp - Filter a list into two parts by a predicate -

i want do (filter-list-into-two-parts #'evenp '(1 2 3 4 5)) ; => ((2 4) (1 3 5)) where list split 2 sub-lists depending on whether predicate evaluates true. easy define such function: (defun filter-list-into-two-parts (predicate list) (list (remove-if-not predicate list) (remove-if predicate list))) but know if there built-in function in lisp can this, or perhaps better way of writing function? i don't think there built-in , version suboptimal because traverses list twice , calls predicate on each list element twice. (defun filter-list-into-two-parts (predicate list) (loop x in list if (funcall predicate x) collect x yes else collect x no (return (values yes no)))) i return 2 values instead of list thereof; more idiomatic (you using multiple-value-bind extract yes , no multiple values returned, instead of using destructuring-bind parse list, conses less , faster). a more general version be (defun split-list (key list &
