<0> um, since when?
<1> std::strings have iterators too
<2> I don't know, but it seems so
<1> you can treat them as another sequence
<1> std::string::iterator iter = s.begin(); //first character
<1> iter++; //now *iter is second character
<2> for )int i = 0; i < str.length(); i++)
<1> yes they also have operator[] availab;e
<2> nice
<2> maybe that's all I needed
<1> MAYBE
<1> dum dum dum\
<2> lol
<0> heh
<2> let me try it,
<0> well, there is another way... too
<2> btw [] doesn't work and neither str.at(i)
<2> I don't know why they don't work though
<0> well, there are substrings or you could do str.c_str[i] ?
<0> err
<0> no that aint right
<0> what are you going to use the end result for?
<2> parse a string to format it with one plus sign between each 2 words no matter how many spaces
<0> oh ok.
<2> I'm trying to learn C++ after working with delphi and then pascal
<0> I owuld probably use a stringstream
<0> the stringstream will automagically remove any excess whitespace
<2> yes I used a stringstream with vector as container and it worked
<0> and you can put the peices back together however you want
<2> but I wanted to step through the string
<0> well, you would not even need a vector in theory.
<2> one character at a time
<0> just a std::string for output, and a stringstream
<0> and a temp std::string.
<2> hmmm I found an example that did that but while using a vector
<0> and std::string does support [] iirc
<0> I don't know what you may be doing wrong
<0> as well as substr
<0> but stringstream and a temp std::string works rather well.
<2> let me post the code I used
<2> do you have a minute
<0> ya
<3> in c++ inside a while loop. do i have to use count++ or ++count?
<3> Twister
<3> post or pre
<3> wtf
<4> most of the time it doesnt mater
<3> ta
<0> you have to understand how they work...
<0> ++i; is guaranteed to be as fast or faster than i++;
<0> so ++i; is generally a good habit if the post/pre part is irrelevant
<2> http://www.noidea128.org/sourcefiles/16033.html
<0> http://www.noidea128.org/sourcefiles/16034.html
<0> thats what I came up with
<0> oh geez
<0> your code requires no logic at all...
<0> heh...
<0> use >> operator and all the work is done for you
<1> heehee
<0> its my logic, just with cin instead of ss
<0> So, copy my code, and replace the ss with cin and presto Done.
<2> that's cool and I appreciate it
<0> well, you would want to modify the loop logic slightly with a break parameter of some sort
<2> but stepping through a string should work though, or what am I doing wrong?
<0> I dunno
<0> it don't compile?
<2> I actually typed it in that's why it took some time, because I don't actually have the full code now, because it wasn't working so I erased it
<0> you should use string::size_type
<0> instead of int ...
<2> it doesn't compile because compiler complains about different types
<2> ok I'll try that
<2> thanks, now I have a couple of things to actually work on.
<0> I like my version better than the whole substring search idea though ;)
<2> thanks Twister for your help
<2> lol
<2> it's going to be one line so not much penalty for slowness
<0> you calling my method slow?!
<0> boo hiss ;)
<2> but I thought it important concept to be able to step through a string (although not most elegant or efficient for this particular case)
<0> does the size_type change work?
<2> lol no I'm defintely calling my method slow
<2> haven't tried it yet, hold on and I'll be back in 2 minutes let you know
<0> I think your method may be broken as well
<0> buggy on strings of 3 spaces I think
<2> the logic is based on pascal's method of working with string
<2> so not the best for C++
<2> be back in 2 minutes
<0> well, I am outahere.
<0> Have a happy.
<2> you too Twister
<2> working on it now
<4> Need help, http://www.noidea128.org/sourcefiles/16035.html. This is ATL & Automation stuff, need help desperately
<5> try CoTaskMemAlloc instead of new
<4> should I used sizeof(OBZ) in CoTaskMemAlloc(size_t size) ?
<5> yep
<4> OBZ *obz = (OBZ*) CoTaskMemAlloc(sizeof(OBZ)); //this is my modification
<4> it give the same error
<2> yes tried with string::size_type and I get the same errors as before :) ISO C++ forbids comparison between pointer and integer.
<2> will try now with iterator
<5> still, you should never use new to give back memory to a caller across apartment boundaries; you should always use CoTaskMemAlloc
<4> point taken... I am reading somemore in MSDN regarding this CoTaskMemAlloc
<5> other than that, things look alright to me
<4> thanks ... I'll trouble shoot some more ... maybe this code just doesn't work in C#, I am going to try it from VB
<5> i think i know what's wrong
<4> if I use the DLL from VBit doesnt crash but the OBZ object return from the DLL is basically empty object, all BSTR member are equal tu ""
<5> let me try something, hold on
<4> thanks peterhu... really appreciate your help
<6> khan, once you figure his stuff out, http://planetbattlefield.gamespy.com/
<5> noobs, what happens if you comment out the CoTaskMemAlloc line?
<4> let me try that
<4> OBZ *obz; // = (OBZ *) CoTaskMemAlloc(sizeof(OBZ)); <-- runtime error: Object used without being defined
<5> oh, sorry
<5> i meant comment out the line and allocate directly on the pointer p***ed to you
<5> i forgot you were using a temp
<4> I have been wondering if I can do something like this...
<4> OBZ obz; obz.Type = "P"; ... obzData = &obz; return S_OK;
<5> works fine here: struct Data { BSTR s1; BSTR s2; BSTR s3; ) ... interface IFoo { HRESULT GetData([out, retval] Data* data); } STDMETHODIMP GetData(Data* data) { data->s1 = ::SysAllocString("hello"); ... S_OK; } C#: Foo foo = new Foo(); Data data = foo.GetData(); Console.WriteLine(data.s1); ...
<5> }
<5> L"hello"
<5> was typing that out
<5> you'd obviously want to check data for zero and return E_POINTER
<5> you can't do it that way, noob
<1> lol
<1> oh
<1> his real name is noob :-\
<4> :P ok I'm just asking
<4> I'm still trying to ***imilate the refference things from thiw few weeks input
<5> the COM proxy will p*** you a valid addess of a structure to fill out
<4> Ahhh!
<4> let me try that
<4> thanks a lot
<5> no prob
<5> for you to have allocated the structure yourself, you would have taken a OBZ**
<5> which also works in C# code, but it's uglier, as you have to use the Marshal cl*** to get the structure from the pointer, and then to free the memory that was allocated in the method
<4> this is really educational!!!
<4> It's good that I dont have to do that marshaling thing...
<5> if your method had taken OBZ**, the "[out, retval] struct OBZ**" would have been changed from returning an OBZ interop object to an IntPtr (because you're really returning an address)
<5> yeah, you should be fine now
<5> "would have been changed" = "would have been changed by tlbimp"
<5> that's the first time i've touche COM in almost a year and a half
<5> +d
<1> how does it feel
<5> i feel slightly dirtier
<1> I meant after touching COM, not after touching JB
<6> Boink
<5> jb throw the patch on a server you punk *** bitch
<5> fileplanet = the ****
<6> Blow me, soccer mom
