<0> haha
<1> Oh
<2> YUY0x7: It wasn't aware that it was local sensitive. doesn string hold only ASCII chars?
<0> yeah
<1> Hmm ...
<1> Then \n should most definitly work, it does over here!
<1> Tho both of them appear to do the same thing, I don't think \n clears the buffer, while endl does
<3> likoo, no, std::string is a char container, it's not bound to any encoding
<0> wow
<0> thats really really odd.
<0> NOW \n works
<0> :/
<1> lol
<0> Just.. all the sudden
<1> Hajuu : Dude, stop doing drugs! ;)
<0> actually the problem is that ive run out of weed.. I cant concentrait for crap
<0> :P
<0> -i+e
<1> Ahh there you go! :)
<1> Knew there was a problem ... :)
<2> likoo: OK. I still think they could have done a toLower and toUpper for type specific strings
<1> Then go buy some ... or stop trying to program while you don't have any at your disposal! lol
<0> lol probably sound advice.
<3> likoo, i agree there should be std::tolower that takes a string and a locale
<0> Anyway.. I gotta head off. Will no doubt be back regularly as my c++ adventure continues :P
<1> And don't get a job as a C++ programmer, you'd get fired as soon as they realize you can't work without being stoned! lol
<0> LOL
<1> Hajuu : If you don't have this already : www.cppreference.com
<1> Good reference ...
<3> likoo, but you can write that, it's trivial
<0> ooh
<0> awsome
<0> thanks alot man
<1> No problem!
<1> Good night!
<0> Peace out
<2> YUY0x7:Yes. it is. But then I would have to extend string and use my own strings. right?
<1> TradeMark : Hmm... \n doesn't work, then it does ... lol
<4> heh, odd
<3> likoo no, i mean a namespace scoped function, not a member function
<2> I see
<3> std::string tolower(std::string const&, std::locale const&)
<2> or i could use _strcmpi() :)
<2> to do lower case comparisons
<3> yes, a case-insensitive compare should be better than converting to a common case
<2> is it frowned upon using some C runtimes funtions?
<3> c-bot strcmpi
<5> YUY0x7, unsure on that one ..
<3> c-bot _strcmpi
<5> YUY0x7, you tell me!
<3> likoo, not really.. if there's a better C++ alternative, yes, but otherwise not really
<2> ok
<3> e.g using memset instead of std::fill
<2> true
<2> i wonder if STL and Boost will get wide adoption once they are in the standard
<2> Boost, sorry, STL is already in the standard?
<3> calc stl
<6> stl = Standard Template Library, a group of typesafe collections and algorithms, now mostly part of standard C++. See http://www.sgi.com/tech/stl/ for a reference guide.
<3> ugh
<7> Can someone tell me why myvar is still 123? http://rafb.net/paste/results/Idy8CO43.html
<2> "mostly part"
<4> stl is part of ansi right?
<1> Valmer : Where is the main() function?
<3> it's not correct to call it stl now, imho.. it's just the standard c++ library, or stdlib for short
<3> <cylon> STL is a misnomer acronym first created and documented by HP. It was mostly equivalent to the container and algorithm templates that are part of today's `the C++ standard library'. If `standard library' is too much to type, use `stdlib'.
<7> PM2: it starts with Start()
<3> Valmer, use extern instead of static
<3> static tells the compiler to make 2 copies for each cpp file
<3> calc extern
<6> extern = How to declare a variable in one file and use it in another: <http://www.gnomesane.net/code/extern/>;
<7> Really?
<2> what is the best and fastest way to check for a NULL ptr on the beginning on like a group of 100 methods belonging to the same cl***, and that use that pointer? I made an "inline" method that checks for null and throws an exception, and I call it at the beginning of each method. It feels 'lousy' though
<7> I thought static was always included ONCE globably.
<1> Within the file it is declared in ...
<1> But it's not visible from outside
<3> likoo, hmm, example?
<2> A::method1{checkPtr();...} A::method2{checkPtr();...} A::checkPtr(){if (!m_ptr) throw...}
<2> the ptr is set at constructor
<2> but i am afraid that the calling cl*** destoys it and still calls one of my methods
<3> hmmm
<3> if you really need to check it every time, i don't know any other way right now
<2> the whole code in that "utilitarian" cl*** depends on that pointer being valid
<2> would one usually check for the PTR? or just leave it to caller to make sure that it is valid at all time?
<3> it depends..
<2> ok
<3> for example, a smart pointer cl***'s operator*() usually does not check the validity of the pointer it's dereferencing
<3> (operator*() is dereference btw)
<2> ok
<2> if it poins to a null pointer then the application fail
<3> yes.. you'd check before dereferencing like you do a normal pointer... if (pointer) *pointer = 10;
<3> checking every time it's dereferenced or operator-> is used can be inefficient
<2> the fact of the matter is that this "utilatarian cl***" was part of the cl*** that is now calling it. and the cl*** that called it is the one managing the pointer. I decoupled the cl*** into two cl***es to make the first cl*** not so big and easier to maintain
<7> I've never seen the extentions .hpp. Is that common for a header?
<3> likoo, hmmm ok
<3> Valmer, yes they're common in C++
<3> boost's headers are all .hpp
<3> it's not that it matters though, you can use any extension, or none at all
<2> I am rethinking my decision now :-/ ... i like modularity. And I don't want to have an "important cl***" with 100 setter cl***es, although logically they do all work on the same data
<2> so now I p*** through pointers to my decouple cl*** the data it needs to modify
<7> YUY0x7: You said use extern... but how do I initilize the global extern variable? What I want is an global variable initilized to 123.
<3> <6> extern = How to declare a variable in one file and use it in another: <http://www.gnomesane.net/code/extern/>;
<3> ah, they don't say where you can initialize
<3> initialize in the cpp
<7> cpp....Hmmm I shall give that a try :)
<7> YUY0x7: Ok I made a quick example. I don't know where to put 'int myvar'.
<7> YUY0x7:http://rafb.net/paste/results/KWSjtv91.html
<3> http://rafb.net/paste/results/KWSjtv91.html
<3> you didn't make it extern?
<7> Well.... If I change static to extern....where would I place 'int myvar'.
<8> looks complicated i better sit this one out :p
<3> extern int myvar; // in the .h
<3> int myvar = 123; // in one .cpp, any
<7> Hmmmmmmmmm I tried that and it didn't work.....hmmm let me give that a try again :)
<7> YUY0x7: I initilize myvar2 in OnInitDialog()... http://rafb.net/paste/results/zJWcGC43.html
<7> It's not working how I wish for it.
<3> um... not inside any function
<3> this is a definition... int myvar = 123; // notice the type in there too
<7> Yeah...where do I place.... int myvar = 123 ? Where should I initilize it? Ok so not in OnInitDialog()...but then where?
<3> in line 61 for example
<7> Hmmmmmmmmmmmm Let me try that. :)
<7> YUY0x7: Very useful.... Ok.... I like that.
<7> YUY0x7: I really appreciate your input and help.
<3> np
<9> can i convert int to string?
<3> calc convert
<6> convert = Using the 'translators' built into the C++ stream libraries (which are extendable), a simple conversion technique is: #include <sstream> std::stringstream tempstream; tempstream << whatever; if ( tempstream >> whateverelse ) // conversion worked!;
<9> omg
<9> so c++ has no toString() function?
<3> No
<3> you can write a function if you find it too verbose
<3> (or just use boost::lexical_cast
<3> )
<3> calc convert2
<6> convert2 = A nice way to convert between data types is to use a templated function to wrap around stringstreams. For Example: template<cl*** TO, cl*** FROM> TO lexical_cast(FROM blah) { TO t; std::stringstream ss; ss<<blah; ss>>t; return t; } . USE: TYPE d = lexical_cast<TYPE>(someString); *Note* this exists in boost as boost::lexical_cast in a better form (with error checking).
<9> tnx

<8> !g kniht
<10> How can I code a program to take a screenshot of a specific part of the screen and "read" that screenshot ?
<10> ... It sounds like a trojan function, but it's really not.
<1> Hey guys
<1> Quick question for you!
<1> How do i clear the console window? Erase everything in it?
<3> not standard
<1> Not possible?
<1> So I have to use system("cls") ?
<3> that only works in windows
<1> I know, and that's my problem
<1> I need something that'll work in Unix and Windows
<10> Another try : How can I code a program to take a screenshot of a specific part of the screen and "read" that screenshot ?
<11> try doing some research - start at google
