question~ SolidWorks 2005 API: using IGetChildren

I have a question about using IGetChildren in SolidWorks 2005 API in
Visual C++ 6.0

Suppose I have an Assembly file containing 3 part files.
I would like to use the IGetChildren function to get the name of each
part (component) one by one, using the code below.
But after IGetChildren is called, in the pChildren array, only the
first element gets the first part. The remaining elements could
retrieve nothing.

Would someone figure out why IGetChildren() cannot get all the children
(parts) in this case?
Many many thanks!





IComponent2** pChildren = NULL;
CComQIPtr<IModelDoc2> pModel;
CComQIPtr<IConfiguration> pConfiguration;
int nChildren, i;
if (pModel->IGetActiveConfiguration(&pConfiguration) == S_OK )
{
if ( pConfiguration->IGetRootComponent2(&pRootComponent) == S_OK )
{

HRESULT hres = pComponent->IGetChildrenCount(&nChildren);
if ( S_OK == hres && nChildren > 0 )
{
pChildren = new IComponent2* [nChildren];
hres = pComponent->IGetChildren(pChildren);
if (S_OK == hres)
{
for ( i=0; i<nChildren; i++ )
{
// code to do tasks like getting name, ...

// but now only OK for the first element!
}
}
}
}
}
