<0> i don't need that precision
<1> you expected a 'z' value of '0'... what are you getting?
<0> a wrong value from a wrong calulation
<1> I don't think I can help you
<0> the precision i actually use cannot create a difference of 0.08 using a r of 0.5
<1> wow, so tired
<0> if i get the concept right... giving a value of 90 to the x angle (theta) the Z should be 0 whatever the Phi angle (z angle)
<2> StaZ[home]: the angle should be in radians, not degrees...
<0> yeah i do r * cos(90.0f * (360.f / PI)); thats right?
<0> huh no...
<0> that's not what i do...
<0> omg my head aches
<3> 180/PI
<3> since 2PI = 360 degrees
<4> PI/180
<3> that too
<3> 90/(2pi)
<3> erm.. no :P
<3> gah its early
<4> ;)
<3> 90/(180*pi)
<3> :P
<3> meaningless~~~~
<0> okay you're mixing me up... it's pi/180 or 180/pi ?
<4> PI/180
<3> well 360 degrees the same as 2PI radians
<4> angle in radians = angle in degrees * PI/180
<4> and what's with the float literals?
<0> so there's something wrong... z = 0.5f * cos(90.0f * (3.14159265f / 180.0f)); <- this should return 0 no ? it returns me -2.1855694e-008
<4> that *is* 0
<4> stop using floats
<4> and you might get closer ;)
<0> O_o
<4> you know it all gets promoted anyway
<0> ... how can you write this line without using floats?
<4> in most places there is no advantage to using float
<4> z = .5 * cos(90 * M_PI / 180);
<0> cn28h well opengl takes floats and this Z will be used in a gltranslate
<4> well then at least use cosf
<4> cosf()
<4> rather than cos()
<4> mind you cosf() is from C99
<4> but the answer is really, you *are* getting 0
<0> i don't get it... i did a lot of sin/cos in 2d planes... and saw a bunch of snippets of code using floats in there and i did.. and never got a single problem why now i get errors?
<4> what is the error?
<0> you say i am getting 0... why don't i see my variable witha value of 0 ?
<4> that the answer is one 200 thousandths of a radian off?
<4> that's pretty damn good for a float
<0> omg... okay i get it now...
<0> stupid me
<0> someone kill me plz
<4> haha, it happens
<2> or, use Mathematica or something ;)
<0> i was reading -2.1855694e-008 as being 0.021855694
<4> heheh
<4> yeah, that'd do iut
<0> ok so that value will do finally
<0> lol
<4> could be worse, iirc allegro liked to define circles with 256 degrees :)
<0> lol
<0> thanks for reconforting me :P
<5> OpenGL takes doubles too
<6> 8 (... why does my program no output a cout<< till after processing has finished?
<4> |P|H|P|, it's probably not getting flushed
<4> add << endl;
<4> bedtime
<4> 'night
<7> wth... why is the compiler not finding the inherited pure virtual functions from this abstract cl*** in its derived cl***...
<7> oh! silly me
<8> forgot to actually derive from it?
<9> sal lume
<8> english.
<9> :))
<8> yeah you do that double-chin you fat bastard
<7> EwIck: no, forgot to define the functions in the derived cl***' declaration
<8> meh.
<10> I am making a win32 project in visual c++. i want to know if i can change the state of a menu item. For example i have a menu item with the id IDM_019, that is checked, how do i uncheck it?(when it is clicked)
<8> CheckMenuItem
<10> thanks
<11> is there a place where I can read about all the commands/functions available in c++, kinda like php.net when you search through all the functions?
<12> Hi
<12> how to make gcc compile with large file support
<13> ref = Some C++ Reference Sources: (1) Your compiler documentation (2) http://www.dinkumware.com/manuals/reader.aspx?lib=cpp (3) http://msdn.microsoft.com/library/en-us/vcstdlib/html/vcoriStandardCLibraryReference.asp?frame=true (4) http://www.sgi.com/tech/stl/ (5) http://www.cppreference.com (*) http://www.google.com
<13> d***rull: for the most part, read the docs for the libraries you're using, for the standard libraries the standard is a good reference, but there are plenty of other sources
<10> can anyone look over the code i posted at noideea.org?(it's a win32 program). unchecking ID_019, ID_013, ID_016 works but uncheking ID_012 does not work
<10> thank you
<13> what's the url?
<10> www.noidea128.org, my name is BUFU
<10> it's tha last one posted i think
<10> I started the project in visual c++ 6, then continued it in vsc++ 2005. The first time i compiled it, after adding the check/uncheck code, i got an error that ID_012 does not exist
<10> i modified the resource, added the id to the coresponding menu item
<10> but now the code does not work
<10> for ID_012
<11> Kniht :: Thank you!
<10> http://img207.imageshack.us/my.php?image=id0126wi.jpg as you can see in this link the id is put correctly
<10> i've put on the site even the resource.h file.
<10> could it be from the fact that the last menu id was made in vs2005, and all the other ones in vc6?
<14> hi
<14> nick /melissa18
<14> aaahhhhh!!!
<10> =))))))))
<10> :))
<11> I'm modifying the searchapp htdig. It's String.cc file does not have find, rfind, find_first_of and so on. How can I implement i.e: strrstr, find, rfind into this stringcl***?
<11> I am very new to c++ btw...
<15> Why would you want to add that to the cl***?
<15> And why does htdig imlement its own string cl*** at all?
<11> because I need it to find and output text after the last occurence of a word I am searching for, but it only has strstr, so I can only output text from the first occurence of text I am searching for
<11> and I do not know why they have their own minimal string cl***...
<15> Does htdig's string cl*** offer iterators?
<11> Not 100% sure what iterators are, but I think so yes. It can iterate over a string and output the text, I'm not quite sure what it does..
<15> If you have iterators then you can use std::find and std::search on them.
<16> how is FlatStyle implemented in .NET ? ie I want to inherit from (User)Control and added a Borderstyle (using CreateParams) and it draws a sunken 3D border, not an XP border like a TextBox/ListView has when FlatStyle is set to Standard
<16> anyone ?
<11> will try..
<15> frankly, htdig's string cl*** is a good example for a bad string implementation.
<11> 'cl*** String' has no member named 'find' .. So, is there any way I can take find from someone else's String cl*** and implement it into this one.
<15> It not only does not integrate well with the standard library, it also contains a large number of mechanical errors.
<11> mkay
<11> but still, its a great searchengine... until I had to start messing with the source
<15> really, that string cl*** is remarkably bad written. I'd fire a person who would suggest such code.
<15> And, no, it doesn't offer iterators.
<11> hehe, thats why its a LGPL app
<15> figures.
<15> more than 90% of all *GPLed code is crap.
<17> hello
<11> Which is understandable. If you don't get payed for making it, just make it so it just barely works.
<15> you could add .begin() and .end() member functions that return char * instances. Those character pointers are iterators. I.e. you can use the standard algorithm, esp. std::find and std::search on them.
<17> whats the difference between " x01\x00\ " and " 0x01, 0x00, " ?
<15> d***rull: I disagree. If you volunteer for an open source prohect then you don't have any reason to write crappy code.
<10> why does CreateWindow("NAme1", "text2",...) generates an error because of the first 2 parameters?
<11> Personally, I would put effort into it, but I can understand those who don't aswell
<11> thanks for the tip, I will try it out
<10> it works in vs6 like that, but in vs2005? it says that the parameter is wrong type
<15> You can also add functions .rbegin() and .rend() that return instances of std::reverse_iterator<char*>. Using those together with std::find and std::search will enable you to perform backward searches.
<15> (you'll need to check out the iterators section of your C++ book and the algorithms section, too, I guess)
<11> thank you, feel free to keep throwing tips at me..
<18> any of you guys running sql server 2005, can you tell me what accounts are needed to run it? i installed the domain controller software on the same machine and thing it deleted the sql accounts...
<15> How is that related to C++?
<10> how do i convert an integer to string? for TextOut?
<19> std::stringstream is your best bet
<15> calc convert
<13> 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!;
<20> why are arrays p***ed to functions by reference? is it because at those times when C was invented, people thought "oh arrays are so huge, nobody will ever want to p*** them by value"?
<21> holy ****
<22> no, melissa18
<21> a question from a nick of <girl><number>
<21> that's a record!
<22> heh
