A tool to implement Interface

[TouEnMasm]

Hello,
This tool do the hard work to implement an interface,he generate:
* The prototypes
* the table of vectors
* The procs
He give a very few code in comment
can work in 32 or 64 with not too much problem

Run it,and give "NamedInterface,Fullpath.SDK"        ( The Interface must be described in the header)

example:

IClassFactory,h:\sdkrc100\um\unknwn.sdk

output:

.const

Hi TouEnMasm,

is it possible to convert classes in the same way ?!

[TouEnMasm]

Hello,
I think you want to speak of C++ classes who use a very similar writing with Indirect addressing ?.
Goal will be to have a translate of them in asm.
It seems to me possible , manually,with a few work,to do that on not too much complex ones.
But this need further manual samples before to automatise that.
