<0> nope
<1> whats is for?
<1> sorry for my eng
<2> char **p; <-- pointer to pointer to char
<0> well I don't actually know, but that looks like bad c++ language
<0> oh ok, my badd
<2> double pointers are actually very useful
<1> cn28h thanks
<2> np
<1> so thats mean that
<1> if i have char *t;
<1> i can use p to point to t?
<2> yes
<2> p = &t;
<1> nice
<1> and thanks again
<2> np
<0> can you help me now?
<2> help you what?
<0> masterbate, I need a hand here
<0> c++ code
<0> MFC crap
<2> MFC isn't part of C++, and really I know nothing of it, sorry
<0> ok, so b it
<2> I'm mainly a *nix programmer
<0> cool
<0> I want to get into linux
<0> debian
<2> I run Slackware, here
<0> that's supposed to be the best
<0> I'll work my way up to it though
<2> what's supposed to be the best?
<3> emacs
<2> (I actually did try MFC once about, oh, 5-6 years go, but I found it harder to use than straight Win API)
<2> emacs is nice
<4> cn28h "when?" are double pointers useful?
<0> cool, yeah I did a little of that Win API
<0> should I start nix with debian?
<2> when you need to modify a pointer in a function? perhaps you are interfacing with C code -- or if you need to build a dynamic 2d array (I know this can be done with STL)
<4> I meant in C++
<2> sure, it works fine in C++
<4> change a pointer in a function? reference to pointer
<2> either way, reference is just syntactic sugar for a pointer anyway
<2> pfloyd345, never used Deb, but it's supposed to be good
<4> cn28h somebody has taught you wrong
<2> how so?
<3> When you have a crappy UML generator that models one-to-many aggregates as pointers to pointers
<3> (in C++)
<4> try overloading say operator + withOUT using your "syntactic sugar"
<2> I didn't think you could overload operators on primitive types
<2> wouldn't really make sense
<4> cn28h what's that have to do with what I asked?
<0> well, just wondering, my program is moving certain things with the movement of the scrollbar, but it's not removing the old ones, ne1 know why?
<2> pointers are primitive types, no?
<0> brb somking
<4> cn28h yeah, what about it?
<2> so you can't overload an operator for them
<2> you just overload it for the type it points to
<4> I said try overloading operator + (for ANY type) without using references
<2> and dereference
<2> oh
<4> oh
<4> try writing a copy constructor or and ***ignment operator without them
<2> but this is a different context
<2> from modifying in a function
<4> I was just challanging your statement that ** is useful and suggested that *& is "more useful" and you decided to ***ert that reference is "just synctactic sugar"
<2> well I'm not trying to say they're useless, but I don't see why you would say that ** isn't a valid way to go in C++
<2> some functinos use them even, like std::strtol
<4> lol, yeah, picked up from the C library
<2> ;)
<0> well, just wondering, my program is moving certain things with the movement of the scrollbar, but it's not removing the old ones, ne1 know why? <- mfc
<4> and YOU don't need to use them to use strtol, strtol does
<2> well, what if you want to use one of the execv*() functions? not C++, but a POSIX function
<4> and strtol is written in C
<2> no c-bot :/
<2> it lets you run another process
<2> and it takes a vector of arguments
<2> for argv
<5> I'd wrap the function in whatever it would take for me not to have to worry about a pointer.
<5> And the optimizer would reduce it to whatever I'd have had if I'd created appropriate C code with necessary error checking.
<2> well, you'd have to worry about them in the wrapper :)
<5> Once.
<5> Anytime I have to interface with C code, that's usually what I do.
<5> And that's what you're describing: A C interface.
<5> As in, not C++, so no references or std::vector or whatnot.
<2> well, it is a C interface, but C++ was built to be able to interface with C, and most C even is valid C++
<5> Yes. And C++ provides better ways to abstract away the inherent nastiness of C.
<5> Which I use every chance I get.
<2> heheh, well I won't disagree -- C++ does make things a lot easier
<6> CrazyBandit CrEw OwnEz mE!
<7> ...
<2> haven't seen that in a while
<4> that's the 2nd one I've seen in a week
<2> I actually have to write some secure C string handling functions right now for one of my cl***es, it's going to be a challenge
<4> cn28h point out to your prof it would just be simpler to use C++ (it's a better language anyway)
<2> well, he said it's a good example why we should investigate using other languages when possible
<4> or just grab the src directory for MS's new "secure" C library
<2> I like C, simple and powerful, but it's true that it's hard to cover all the boundary conditions
<2> well, I develop on Solaris mostly :)
<2> but I am trying to get back into Windows dev a little
<4> they _had_ a C++ compiler
<2> they do
<2> CC
<4> it had a few gotchas when I was using it 5 years ago
<4> I think we were using Forte
<2> do you play with .NET at all?
<4> which had a very nice featur in it's debugger... yuou could load a "core" file and it would put you right at the place in the program where it blew up
<4> not yet
<2> ah, like gdb?
<2> ok, I'd like to use .NET if I can make portable GUIs with it, but I'm not sure i tha'ts possible or not
<4> dunno, the last gdb I used was "console only"
<2> I know there is gtk# and Qt# but I don't know if those only work on Mono or if they work on MS .NET Framework too
<4> mono works on *nix, I'm told
<2> yeah, gdb is console only
<4> Qt certainly had some very nice controls... I liked the "radio dial" with inertia..you pushed it and it coasted to a stop
<5> I haven't played with Mono's implementation of Windows Forms in a while, but when I did it was already binary portable.
<5> As is anything else, really.
<2> hm, cool
<5> So a GTK# program will run anywhere that has GTK# ***emblies for the platform, just like Swing.
<2> so I can use Windows forms on *nix Mono?
<5> Except better, of course.
<2> ah
<2> yeah, I never cared for Swing
<2> AWT isn't a treat, either :)
<2> they're not bad, but they don't look like natie GUI programs
<2> native
<0> u guys can't talk MFC in here?
<8> What do you need, pfloyd?
<0> I need to get these extra text's off my screen
<0> I have a program that will draw text with the scrolling of the mouse
<0> it does move with the mouse but when I scroll to the left again it still shows all the things,
<0> all the other ones...
<8> That's a bit tricky
<0> yeah, I'm using the OnScroll member function
<8> Nope, I don't remember how it's done offhand
<8> If you check out some of the edit controls at codeguru.com, you should see stuff like that
<0> it's ok, I'll find out sooner or later
<0> ok, ty
<8> I imagine the principle would be the same in any library
<0> well, I actually moved the elements, but I guess I need to call an onupdate for when I scroll
<0> do people from other countries have a harder time learning computer related subjects than people here in the US?
<8> Indians don't seem to
<8> Honestly, I don't know
<8> I'd imagine there are fewer translated books available
<0> I've seen some elite looking indian people who are programmers but it could all be appearance
<9> pfloyd345: There is books and intelligent people outside US ;)
<8> Haha
<0> I know foo, but how is the translation and the ability to write code?
<0> lol
