Oracle server encoding and file encoding -


i have oracle server dad defined plsqlnlslanguage danish_denmark.we8iso8859p1.

i have javascript file loaded in browser. javascript file contains danish letters æøå. when js file saved utf8 danish letters misencoded. when save js file utf8-bom or ansi letters shown correctly.

i not sure wrong.

try set dad 

plsqlnlslanguage danish_denmark.utf8

or better

plsqlnlslanguage danish_denmark.al32utf8

when save file ansi typically means "windows codepage 1252" on western windows, see column "ansi codepage" @ national language support (nls) api reference. cp1252 similar iso-8859-1, see iso 8859-1 vs. windows-1252 (it german wikipedia, table shows differences better english wikipedia). hence 100% correct setting have set plsqlnlslanguage danish_denmark.we8mswin1252.

now, why correct characters when save file utf8-bom, although there mismatch .we8iso8859p1?

when browser opens file first reads bom 0xef,0xbb,0xbf , assumes file encoded utf-8. however, may fail in circumstances, e.g. when insert text input field database.

with plsqlnlslanguage danish_denmark.al32utf8 tell oracle database: "the web-server uses utf-8." no more, no less (in terms of character set encoding). so, when database uses character set we8iso8859p1 oracle driver knows has convert iso-8859-1 characters coming database utf-8 browser - , vice versa.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
