I have made a programm using the mysql++ API for the visual studio 7. The=
=20
code is:

try
{
Query query =3D con->query();
ostringstream strbuf;

query<<"select * from vsr";

log << "query=3D " << query.preview() << endl;=20


Result res =3D query.store();

Row row;
Result::iterator i;
for (i =3D res.begin(); i !=3D res.end(); ++i) {
row =3D *i;
cout << row.lookup_by_name("vsr_regtime");
}

}
it creates the following error when it reaches the command row.lookup(..):
Unhandled exception at 0x100119a1 in simple1.exe: 0xC0000005: Access=20
violation reading location 0x8054a938

Have you any idea where is the problem causing this error?

7.0 or 7.1? And which version of MySQL++?

Does this happen with the stock examples? simple1, custom2, and custom3
all use Row::lookup_by_name().
