Here is an ATL project for viewing all "classes" from a dll, tlb, or ocx, in fact library files. User can read some of informations, like functions(methods and properties) from a file, only if that file has a resource "TYPELIB"\1 in resource component. I use the LoadTypeLib file to provide a pointer to a ITypeLib interface. From the ITypeLib interface you can find all that library know (functions, variables, names, ...).
Classes and Interfaces uses in project
ILClass (CLClass) - This interface provides informations about one "class". I define "class" to be a : enum, record, module, interface, dispatch, coclass, alias, union or max .(kinds) User can find the name (get_Name ), kind (get_Kind), count of functions, function (get_Function), count of variables, variable (get_Variable) of this "class". get_Function(int nIndex) function returns pointer (ILFucntion*) to the function nIndex from class. get_Variable(int nIndex) function returns pointer (ILVariable*) to the variable nIndex from class. In both cases, functions will return NULL, if nIndex is not found in range (0..GetCount...() - 1).
ILFunction(CLFunction) - This interface provides infromations about one function. User can find name (get_Name), kind (get_Kind - virtual,purevirtual,nonvirtual,static,dispatch), invoke kind (get_InvokeKind - function(1), get(2), put(4),putref(8)), documentation (get_Documentation), ID (get_ID), parameters and return type. If you want one of the function's parameter, wou have to call get_Parameter function. You have to pass the index of parameter, and this parameter will return the pointer to one parameter interface (ILParameter*).
ILVariable(CLVariable) - This interface provides informations, like name, type and kind (persistance, static, const or dispatch) of one variable.
ILParameter(CLParameter) - This interface wil return informations such name (get_Name, and type (get_Type), of one parameter.
DEMO program And Source(Updated)
Now one can even watch interfaces of a particular object. Demo application in VC++ included.
This is how DEMO VB program looks like :-
A new DEMO program has been added in VC++
The demo project VB requires XPropertiesWnd ActiveX control. See A set of two activeX controls article.
