I am using Visual Studio 2008, C++

I have this line of code in my program:

IloNum r = cplex.getValue(varX[i][j]);

Which is called after I solve a model. When that line is commented there are no problems (other than I can't read my results). When that line is not commented and I try to run the program, I end up getting this error message pop up: Unhandled exception at 0x7655b9bc in routemodel.exe: Microsoft C++ exception: IloCplex::Exception at memory location 0x0018f2b8..

It opens up tidtable.c and takes to here:

_CRTIMP PFLS_GETVALUE_FUNCTION __cdecl __set_flsgetvalue()
{
#ifdef _M_IX86
PFLS_GETVALUE_FUNCTION flsGetValue = FLS_GETVALUE;
if (!flsGetValue)
{
flsGetValue = _decode_pointer(gpFlsGetValue);
TlsSetValue(__getvalueindex, flsGetValue);
}
return flsGetValue;
#else /* _M_IX86 */
return NULL;
#endif /* _M_IX86 */
}

Specifically it points to the error being on this line: PFLS_GETVALUE_FUNCTION flsGetValue = FLS_GETVALUE;

I don't have the technical understanding to have any idea what's going on. How do I fix this?

Also, I have tried it with bool and int r as well (the variable is a bool).

Two things I would check:

1. Does your model solve to optimality? That is, if a solution is not reached, you generally cannot obtain the variable values.
2. Are the indices on i and j valid? (i.e. within the bounds of the array?)

One more thing to check: is variable

X[i][j]

properly initialized? Is it possible that the variable de-allocated before you query the value? Does the error occur with any values for i and j that are within the range of the array or only with some particular values?
