Hi,

i have query regarding ubound in c++ and vb .


in VB they have done like below:

UBound(muEntData) and some times UBound(muEntData,1) what the difference between two as

muEntData is a Type(VB) or structure


in C++ iam using vector with structure muEntData how to do it in vector as

If m_nPntr(int) = UBound(muEntData) ( this is there in vb) and how to do it vector c++ condition

What I have tried:

i tried i like this:

std::sort(muEntData.begin(), muEntData.end());
std::vector<mtentdata>::iterator up;

up = std::upper_bound(muEntData.begin(), muEntData.end(), 1);
int k = up - muEntData.begin();
if ( m_nPntr == k)


error C2893: Failed to specialize function template 'unknown-type std::less<void>::operator ()(_Ty1 &&,_Ty2 &&) const' c:\program files (x86)\microsoft visual studio 12.0\vc\include\algorithm
