Hello,

Nevermind I figured this out, and it is not worth answering on here.

Hello all,

I have a class called Wheel, and I created a boost shared_ptr to this class in the following way:



typedef boost::shared_ptr<Wheel> WheelPtr;


I also have a vector of these...

Hello,

I am tryign to use the Singleton design patterno on Linux, but it is not working:

How would you fix this code? I am stumped!

Hello,

strcpy(buf, "12345678");


When I run this from the IDE in Release mode, it works fine, no crashes. However, when I change "12345678" to...

Hello Paul,

Do you have any sample code with that function? I can't much about it online.

Hello all,

I get the following linking errors when trying to compile my exe:

1>MSVCRT.lib(MSVCR100.dll) : error LNK2005: _tolower already defined in libcmt.lib(tolower.obj)...

figured it out.. typo in my code:

::SetDIBits(dc.m_hDC, bitmap, 0, dyextent, &bits_[0], &bmi_,0);

should be:

::SetDIBits(dc.m_hDC, bitmap, 0, dyextent, &bits1d[0], &bmi_,0);


Thanks...

hmm ok, so my code looks like this now:



in .h file:
vector<vector<int> > bits_;

vector<int> bits1d;
bits1d.reserve(RADARWIDTH*RADARHEIGHT);
for(unsigned int i=0; i<bits_.size(); ++i)

Hey Paul,

I get this compilation error:

error C2440: 'initializing' : cannot convert from 'std::vector<_Ty>' to 'const std::vector<_Ty> &'

on this line:

const vector<int> & v = bits[i];

Thanks for the replies gentlemen :)

Hello all,

I have a 2d vector like this:

vector<vector<DWORD> > bits = vector<vector<DWORD> >(100, vector<DWORD>(100));

I would like to, in code, convert this vector to 1d like this:
...

Would it be sufficient to write code to convert the two vectors to one single vector to be passed in? Anyone have any example code to do that?

Hello all,

Thanks Lindley :)

Hello all,

In code, I need to transform these values:

256 becomes 0
128 becomes 1
64 becomes 2
32 becomes 3
16 becomes 4
8 becomes 5

Thanks everyone! Except S M A :P

I need to use dynamic memory because I am sending the vector to another thread.

How does the allocation work? I tried this code below and it crashes on the reserve() call.



vector<Test*>*...

Thanks so much, I appreciate your time today in helping me! :)

I have a pointer to a vector that contains instances of class Test:



vector<Test*>* testVec;


If I do this:
