Need simple example of creating a thread (during a long process)

I would caution you that some database interfaces do not permit access
from
a secondary thread: see your docs. But this is how to run a bare
essentials worker thread...
// .h
UINT ThreadFunc(LPVOID pParam); // not a class member
// .cpp
// call from within CYourClass
AfxBeginThread(ThreadFunc, this);
UINT ThreadFunc(LPVOID pParam)
{
CYourClass* p = (CYourClass*)pParam;
...do things with p->data_members
return 0;
