Exception error using AVICOMPRESSOPTIONS

I am having problems using the AVICOMPRESSOPTIONS structure in my program in Borland C++ Builder.  I declared the structure and used it in the following manner:
AVICOMPRESSOPTIONS *compopts[3];

compopts[0]->dwFlags = AVICOMPRESSF_KEYFRAMES;
<Exception error right here...>

It compiled fine until the "compopts[0].." line gets executed...  The compiler gives me an exception error saying "Access violation at address ... .  Memory read FFFFFFFF"
(Or something to that sort).
Can someone please help?  Thank you.

Sincerely,
Dan

You use pointers array but you didn't allocate memory. Do like this:

AVICOMPRESSOPTIONS *compopts[3];

for( int i=0; i<3; i++ )
 compopts[i] = new AVICOMPRESSOPTIONS;

compopts[0]->dwFlags = AVICOMPRESSF_KEYFRAMES; // must be OK

Be sure to use:

for( int i=0; i<3; i++ )
 delete compopts;

when you will not need "compopts".
