c++ - Why not have access to the element? -

here code:

#import "c:\...\.....\....tlb"  using namespace std;  int main() {        hresult hr = coinitialize(null);     _applicationptr myapp("indesign.application");     documentptr mydoc = myapp->activedocument;     swatchesptr myswatches = mydoc->swatches;      cout << "number of swatch: " << myswatches->count << endl; // count = 10      swatchptr first_swatch = myswatches->item[1l];     swatchptr second_swatch = myswatches->item[2l];       cout << first_swatch->name; // correctly     cout << second_swatch->name; // crash      cin.get();     return 0; } 

why can not access elements? count 10. ideas?

the line swatchptr second_swatch = myswatches->item[2l]; compiles, empty.

error when accessing second_swatch->name:
