Re: VS2008 and Iterators

The below statement works in VS60
   m_viSOFMarker = m_viEOFMarker = m_viReadIter = 0;

Now, in VS2008, we get a compilation error


1> c:\program files\microsoft visual studio
9.0\vc\include\vector(405): could be 'std::_Vector_iterator<_Ty,_Alloc>

We get the same for " ! " and "!=" operators
   if( ! m_viSOFMarker ) m_viSOFMarker = m_vBuffer.begin();

ANy reason why this is happening? Do we need to create operator!=,
operator= and operator! functions? I found something in MSDN that said
iterators have changed but I'm not following. I'm sure this is simple,
but I'm missing something. We're upgrading all source to VS2008, but
need it to still work in VS60 if need be. If need be, we'll do
conditional compiles.

Below is the class definition

#include <vector>
class CMsgFrameBuffer
{
typedef std::vector<char> TFrameBuffV;
typedef TFrameBuffV::iterator TFrameBuffVIter;
TFrameBuffV m_vBuffer; // the data buffer
TFrameBuffVIter m_viReadIter, // stores the next element
to read
                m_viSOFMarker, // denotes the start of the frame
                m_viEOFMarker; // denotes the end of the frame
...
...
}
