Hello swamy Narasimha, For that u have to type cast ur struct pointer to char pointer. But it is quit risky. Becoz as u know that differeint platform use different size for int datatype. And also change possion for date in struct to optimize best space. In both of this case ur data at other end is useless. And that's why some COM component provide fisrt field as sizeofstruct. To conform that both end use same style for data arrangment. regards, Divyang Mithaiwala System Engineer & Software Engineer
