hi,

I am new at this and need some help with error C2440 in VS .net 2003
below:

#include "stdafx.h"
#include "piaLM.h"
#include "piaLicense.h"

#ifdef _DEBUG
#undef THIS_FILE
static char THIS_FILE[]=__FILE__;
#define new DEBUG_NEW
#endif

// create a global object
piaLM piaLM;

using namespace std;
typedef multimap<string, LP_HANDLE *> MapLic;

//////////////////////////////////////////////////////////////////////
// Construction/Destruction
//////////////////////////////////////////////////////////////////////

piaLM::piaLM()
{

}

piaLM::~piaLM()
{

}

bool piaLM::CheckOut(std::string const &fea)
{
    LP_HANDLE * Handle = 0;
    string version;

    version = FEATURE_VERSION; // set to current version

    int status = lp_checkout(LPCODE, // LP code
        LM_RESTRICTIVE, // policy
        const_cast<char *>(fea.c_str()), // feature
        const_cast<char *>(version.c_str()), // version
        1, // number of licenses
        "pia.dat", // (char *) license location
        &Handle);

    if (status != 0){
        string msg = "You need a valid " ;
        msg += fea;
        msg += " license to use this feature. ";

        ::MessageBox(0, msg.c_str(), 0, MB_OK);
        return false;
    }

    m_AllLic.insert(make_pair(fea, Handle));

    return true;
}

bool piaLM::CheckIn(std::string const &fea)
{
    MapLic::iterator itr = m_AllLic.find(fea);

    if(itr == m_AllLic.end())
        return false;

    lp_checkin(const_cast<LP_HANDLE *>(itr->second));
    m_AllLic.erase(itr);

    return true;
}

bool piaLM::IsValid(std::string const &fea)const
{
    MapLic::iterator itr = m_AllLic.find(fea); // This line gives error
c2440

    return (itr == m_AllLic.end()) ? false : true;
}

Thanks!
