You will need to do some debugging to find out where the error is
occurring; but you are probably looking at an empty dataset, viz. if you
call Open (on a query) or First (on a cursor) and are at EOF, then your
dataset is emptyl

In your report's OnNextRecord (or equivalent) event, you can test the
IsEmpty property on a query object or, on a cursor object, test

if ((object->BOF) and (object->EOF))
{

If you are iterating through a dataset, it should be enough just to test
for EOF, viz.

while (!object->EOF)
{
