Back to article list Search Articles Add Comment Printer friendly Direct link COM: Constructing Interfaces 2 2002-12-29 -- Andy Ireland Newsgroups: comp.lang.clarion
This is how you would go about converting the Interface....
IItem interface(IDispatch),com
get_Title procedure(*long bstrTitle),HRESULT
put_Title procedure(long rhs),HRESULT
get_ID procedure(*long ID),HRESULT
....
....
end
The property methods are typically called get / set methods.
IDispatch is as follows....
IDispatch interface(IUnknown),com
GetTypeInfoCount procedure(*long pctinfo),HRESULT
GetTypeInfo procedure(long iTInfo, |
long lcid, |
long ppTInfo),HRESULT
GetIDsOfNames procedure(long riid, |
long prgszNames, |
long cNames, |
long lcid, |
long prgDispId),HRESULT
Invoke procedure(long dispIdMember,
long riid, |
long lcid, |
long wFlags, |
long pDispParams, |
long pVarResult, |
long pExcepInfo, |
*long uArgErr),HRESULT
end
and IUnknown is ....
IUnknown interface,com
QueryInterface procedure(long riid, *long pvObject),long
AddRef procedure,long,proc
Release procedure,long,proc
end
But you must determine whether you can get the raw address first. I
think Jim Kane has shown how to do this in the past.
