I first wrote a COM component with VC. One function in the component has a shape to join a string. The definition is like this: [ID (8), Helpstring ("Method Executea")] HRESULT EXECUTE ([IN, String] char * sqltext); then when I use this method in the ASP, pass the string can't pass. Go in. Can't run correctly. May I, is this function like this? How to deal with? Thank you
