How can i get properties of com object dynamically

[Inam]

Actually i am developing a class in which it will take any com object and will be able to set and get the properties. Now i have taken the clsid of the component. Now how can i get its properties as GetIdsofNames function of IDispatch takes names. Please Guide me briefly with a little example or tell me some article Thanx in advance Regards minamkhan Inam

GetIDsOfNames accepts property names too, but I think you want to know the names of supported properties instead. You need to read the object's type information. You can ask an object if it can provide type information by calling the GetTypeInfo method of IDispatch. You can then find out how many properties it has by calling ITypeInfo::GetTypeAttr. You can get information on the properties with ITypeInfo::GetVarDesc.
