Title: Re: realloc in c++
jak se "ideologicky ciste" v c++ nafoukne pole? v c bych rekl:
pole = (int*)realloc(pole, nova_velikost_pole * sizeof(int) );
dela se to v c++ takto obskudrdne?
assert(stara_velikost <= nova_velikost_pole);
Proc? To snad ani neni treba kontrolovat ...
//nejdriv naalokovat nove
pole_new = new int [nova_velikost_pole];
//pak nejak prekopirovat
for(i=stara_velkost_pole;i--;pole_new[i]=pole[i]);
//a znicit stare
delete pole;
pole = pole_new;
(nekde se tim nekdo zabyval ... me to moc nezajimalo, jsem blbej a na pole
i v c++ pouzivam malloc)
Je to jedina legalni metoda.
v c++ realloc pro new a delete neni hlavne proto, ze funkce realloc
nezajistuje, ze nova adresa bude stejna jako stara. Objekt jako takovy je
nemuze (potichu) fyzicky zkopirovat (musel by se volat destructor, constructor
? ) takze to tam proste neni ...
aspon tak nejat to nejakj chytrej clovek psal ;)
IMHO pokud neco takovyho potrebujes, bylo by lepsi pouzit nejakou sablonu, ty
zmenu velikosti vetsinou umi.
... Nemam rad C++ ... proc zrovna ja musim porat delat neajke low-level veci :(

Title: escape sekvence 033 .. schovaly se ??
Ahojte lidickove,
Potreboval bych prosim poradit v jakem dokumentu muzu najit seznam
konstrukci vsech moznych escape sekvenci pro barvy ... vim ze to jsou
takove ty \033bla;blabla a mam i par prikladu, ale potreboval bych
jejich definici.
Uz sem prohledal veskere soubory v /usr/[share]/doc a tam nevyla
o definici ani zminka (natoz pak zminka o barvach). Kamarad rikal, ze
v jakemsi balicku u Debian 2.1 Slik to bylo napsane vsechno v nejakem
dokumentacnim souboru ... kdyz upgradoval na Potato tak ten soubor
zmizel (a uz si nepamatuje jaky balicek to byl) :((
Nevite kde by se takovy dokument mohl nachazet ????? prosiiim

ze jsem hledal spatne klicove slovo :(((( hmmmm
vsem se tedy omlouvam, ze jsem je s touto trapnou manualovou otazkou otravoval

Treba by to mohl byt tento:
ANSI ESCAPE SEQUENCES
===============================================================================
Wherever you see '#', that should be replaced by the appropriate number.
ESC code sequence Function
------------------- ---------------------------
Cursor Controls:
ESC[#;#H or ESC[#;#f Moves cusor to line #, column #
ESC[#A Moves cursor up # lines
ESC[#B Moves cursor down # lines
ESC[#C Moves cursor forward # spaces
ESC[#D Moves cursor back # spaces
ESC[#;#R Reports current cursor line & column
ESC[s Saves cursor position for recall later
ESC[u Return to saved cursor position
Erase Functions:
ESC[2J Clear screen and home cursor
ESC[K Clear to end of line
Set Graphics Rendition:
ESC[#;#;....;#m Set display attributes where # is
0 for normal display
1 for bold on
4 underline (mono only)
5 blink on
7 reverse video on
8 nondisplayed (invisible)
30 black foreground
31 red foreground
32 green foreground
33 yellow foreground
34 blue foreground
35 magenta foreground
36 cyan foreground
37 white foreground
40 black background
41 red background
42 green background
43 yellow background
44 blue background
45 magenta background
46 cyan background
47 white background
ESC[=#;7h or Put screen in indicated mode where # is
ESC[=h or 0 for 40 x 25 black & white
ESC[=0h or 1 for 40 x 25 color
ESC[?7h 2 for 80 x 25 b&w
3 for 80 x 25 color
4 for 320 x 200 color graphics
5 for 320 x 200 b & w graphics
6 for 640 x 200 b & w graphics
7 to wrap at end of line
ESC[=#;7l or ESC[=l or Resets mode # set with above command
ESC[=0l or ESC[?7l
Keyboard Reassignments:
ESC[#;#;...p Keyboard reassignment. The first ASCII
or ESC["string"p code defines which code is to be
or ESC[#;"string";#; changed. The remaining codes define
#;"string";#p what it is to be changed to.
E.g. Reassign the Q and q keys to the A and a keys (and vice versa).
ESC [65;81p A becomes Q
ESC [97;113p a becomes q
ESC [81;65p Q becomes A
ESC [113;97p q becomes a
E.g. Reassign the F10 key to a DIR command.
ESC [0;68;"dir";13p The 0;68 is the extended ASCII code
for the F10 key and 13 is the ASCII
code for a carriage return.
Other function key codes F1=59,F2=60,F3=61,F4=62,F5=63
F6=64,F7=65,F8=66,F9=67,F10=68
hope it helps, tuttle :)

Title: PostgreSQL + ODBC
Ave
Mam takovy problem. Nainstaloval jsem iODBC knihovnu z baliku, prelozil
PostgreSQL s podborou ODBC a PHP4 s podporou iODBC. A zkousim se pre PHP
nalogovat na ten PostgreSQL. Bohuzel mi to nejde.
Vim, ze se iODBC pokusi nalogovat, PostgreSQL to hlasi. Ale zadva spatne
jmeno uzivatele, jmeno databaze a heslo. PHP potom hlasi: "Warning: SQL
error: Missing server name, port, or database name in call to CC_connect.,
SQL state IM002 in SQLConnect"
Konfigurak odbc.ini vypada nejak takhle:
--
[ODBC Data Sources]
Test = PostgreSQL
[Test]
Driver= <cesta k driveru, je urcite spravne>
Database=mojedb
Port=5432
Servername=localhost
User=test
Password=test
--
Nemate nekdo poneti proc to nefunguje a jak to zprovoznit? Kdyz zmenim v
konfiguraku cokolov, krome "Driver", nema to na komunikaci mezi ODBC a
PostgreSQL zadny vliv, aspon jsem zadny nenasel.
Diky
