Examples

The following example, to be included as part of a larger program, demonstrates how to use InitVariantFromInt32Array.


LONG rgLongs[] = {4, 2};
VARIANT var;

HRESULT hr = InitVariantFromInt32Array(rgLongs, ARRAYSIZE(rgLongs), &var);

if (SUCCEEDED(hr))                            
{
    // var now is valid and has type VT_ARRAY | VT_I4.
    VariantClear(&propvar);
}
