...but if I want to find a sum of variables or access a variable of the parent window then Can I do it ?

int *pValue = new int;
GetParent->SendMessage(MY_MESSAGE, 0, (LPARAM) pValue);
delete pValue;

LRESULT MyParent::OnMyMessage( WPARAM wParam, LPARAM lParam )
{
    *(int *) lParam = 123;
    return 0;
