I am porting an application from VC6 to VS2015. when I am building after including all the header files I am getting the following error

Error C2079 'IDBConnection' uses undefined class 'MIDBODBC::__MIDBODBC_EXPORT_MODE__'

I have included the header file.. but still I get this.

The class where IDBConnection is declared is like this:

namespace MIDBODBC
{
class __MIDBODBC_EXPORT_MODE__ IDBConnection : public CObject
{
protected :
CDatabase* m_pDBPtr;
CMIPLOG m_pLog;
int m_nDBConnectionIndex;
int m_nDBPoolWorkerIndex;

.....

}

Can someone pl suggest how to tackle this error
