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

i create kind of timeline (horizontal line: div) data coming database creation date. place kind of marker (vertical line) automatically on timeline date. the issue timeline div fix size (responsive size in %) when there new data on timeline, others has resize. , example, if have 3 dates: 2009 -2010 -2045 of course there more space between 2010 , 2045 2009 , 2010 ... do have advises / algorithm please? thanks advance if want place them scale, can like: totaltime = maxdate - mindate each date ypercentage = (maxdate - date) / totaltime this put first date @ start, last date @ end, , others in between, proportionally.

$filename=$_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.

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.

scenario: suppose if doing echo 1 > sysfs_entry - start doing i/o operation until echo 0 > sysfs_entry . here, wanted implement timer in sysfs_entry should stop i/o operation after t seconds , if not give echo 0 > sysfs_entry . ps: not want use busy wait methods. preferred: deferred/delayed work please me resolve scenario. you can use add_timer() , del_timer() api this. event queue might work (depends on context). more details, please read chapter 7 «time, delays, , deferred work» of linux device drivers (aka ldd) book available free of charge right here . timer api described on page 198.

is possible have code (server , that) in winform , instead of setting image panel/picturebox, can set wpf (which faster?). if so, operation fast, or have invoke or causes delay in it? i have tried doing this, settings image on wpf winform, sadly wasn´t easy expected. i had windows forms project , able : create new wpf pages : add wpf controls existing windows forms first of need change .csproj in order have option of creating new wpf page , control available. not know heart, it's guid add. from read want second. while on windows forms designer can go toolbox , drop wpf control windows forms. doing vs creates things: 1. wpf control 2. elementhost control you can access wpf control usual accessing variable name.

this question has answer here: why python use 'else' after , while loops? 13 answers i can run below python script without errors. for n in range(3): print n else: print "done" but puzzled else without matching if. not make sense. can 1 explain why works ? the else clause of for , while only executes if loop exits normally , i.e. break never run. for in range(20): print if == 3: break else: print 'haha!' and else clause of try executes if no exception happened. try: = 1 / 2 except zerodivisionerror: do_something() else: print '/golfclap'

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 &...

is possible use viewpager without fragments? examples find load several fragments viewpager. i want use listview . create custom adapter inflate layout according position pager in. if it's possible can point me example ? yes totally possible. since viewpager.setadapter() takes instance pageadapter , need create own subclass of pageradapter (its kinda subclassing baseadapter or arrayadapter use in listview ). remember, pageradapter docs say: when implement pageradapter, must override following methods @ minimum: instantiateitem(viewgroup, int) destroyitem(viewgroup, int, object) getcount() isviewfromobject(view, object) hope helps
