Stack overflow in VB, how to prevent/control

I created a VB program which is in the process of development. The stage
I am in now, I simply acess a data base of 8000 stocks and transfer all
available price data which is available for whatever is in the data base
into indexed locations for (open, high, low, close, volume & date). I
transfer this for each stock and when I am still in the A stocks I get a
stack overflow.  I know what a stack is, but have no idea how to control
same (clear it out or change it's size with respect to VB use of same.
What should I do to control the size, prevent overflow.

Each time I go to access the new stock I cycle through various SUBs
which perform task like 'increment the index' and pass control back in a
loop which possibly produces a continuous series of the same stack
entries.  If I work to prevent these loops, will that solve my problem.
Doing so just makes me repeat the same code in many places and violates
my sense of good practice.   Thanks

Some stack error causes:
1. Reentering some procedure,
2. Usage of DoEvents,
3. Too big local variables (big string or array declared at procedure level)

For 1 and 2 check program logic; add flags to control 'states'.
For 3 - move your big array or string declaration to MODULE level.

If this doesn't help, post some code... e.g. procedure which gives stack error.
