h2incx.exe and h2inc.exe to convert windows sdk headers? netfw.h and others??

[coffeeprog]

Can I and should I convert Windows SDK (Win7 and Win10) to a masm inc format to use for Assembly programming?  I think I can use a utility called h2incx.exe or the microsoft version h2inc.exe to convert C headers to masm32 include files.  Not sure how it works exactly yet.  I want to recode "GetFirewallSettings" project from the Windows 7 SDK to a masm32 version, but masm32 does not have the correct include files.  I feel confident that this is not the only program in the win7 sdk samples that would require headers not included in the default masm32 install.  Suggestions?

P.S. I did find other posts about h2incx.exe on these forums.

GetFirewallSettings isn't an api,a function.It seems usable only with .net (c++)

https://docs.microsoft.com/en-us/previous-versions/windows/desktop/ics/c-getting-firewall-settings
seems more usable with masm but it need interfaces.
the netfw.sdk is usable without corrections and give you the needed declarations to use the interfaces.
You can't use the mlxx with those headers,only(!) uasm,jwasm,asmc,asmc64.

[coffeeprog]

I am not sure what you are telling me?  Are you saying that there is no way to do what I am asking with the Firewall thing?  What about other header files

[TouEnMasm]

For a new coder in masm it could be difficult to do that this way.
If you are enough experimented,no problem.

[fearless]

Looks like a lot of the functions are actually COM based methods for firewall related stuff. Thats probably why its not in the masm sdk. Some of the functionality might be possible in roundabout ways but probably you would need to implement some COM in your masm for that. Best resource for COM in asm is ObjAsm: https://objasm.x10host.com/

roundabout ways of doing this is to check the registry for various firewall related settings to see if they are enabled/disabled, and/or checking status of various known services to determine if windows firewall is running.

You are probably better off just producing any extra header files yourself rather than try and do a complete set, H2INC.EXE was a very old M$ tool that no longer worked on most later (post 1995) files. The later h2incX.exe is not powerful enough to do the conversion and it leaves you with a massive mess. Some of the result may be useful to you but you will have some massive amount of work to do to make it usable.

Some of the guys here have done good work with COM and they may be able to help you.

[coffeeprog]

Well, I am willing to give that a try, but I really am not sure where to start.  I have opened a few of INC that come with masm32 and they really are mostly PROTO and EQU.  I guess the INC would havea Library .LIB file as the other half, right?  I am really not sure how to change what is in netfw.h to an INC file, I don't understand the builtin headers that well.  mostly it is typedefs and defines however.  It also, shows in the header file that there is a difference between it's C++ interface and C interface.  Thank you, I am going to keep trying.  So it will be massive work for just one header or one piece of functionally?  Like netfw.h ? (netfw.h is 4000+ but it is covering both C++ and C i think)

I ran h2incx -i P:\Wind7SDK\v7.1\Include\netfw.h and it generated 86 files with a netfw.inc and others, but there were errors.  I would not know how to test any of these to understand any problems.  Would I need Lib files too?  I also found these pages, but I don't know if they are relevant to this problem:

[hutch--]

I don't know the actual function you are after but there is an alternative if you can hunt up the technical data on the function, Windows has always had 2 functions for individually loading DLLs,

LoadLibrary
GetProcAddress

There are people here who are experienced in setting up COM calls and they may be able to help you.

With LoadLibrary you need to be able to identify which DLL has the function you are after. If you can identify it, you can then test for it with GetProcAddress and if you don't get an error return, you can call it but note that COM is done differently.

Firewall API for C generated from typelib.
It is possible to make similar for asm.

[TouEnMasm]

The Microsoft sample source code had errors (&)
Corrected it and compiled with /FAs,the translation to asm could be useful

[TouEnMasm]

I have find it easy to translate (64),here the result
The translated is named firewall_asm.exe and the c sample firewallref.exe
There is a grammary question thant i let you solve.The two assertions:

NotificationsDisabled are disabled
UnicastResponsesToMulticastBroadcastDisabled is disabled

the upper are of my source

Notifications are enabled
UnicastResponsesToMulticastBroadcast is enabled

Those two are inverted ,The logic is that disabled the disabled  give an enable.
This had been obtain changing the order of the comparison: bIsEnabled ? "enabled" : "disabled" (first two lines) begin bIsEnabled ? "disabled" : "enabled") last two lines
Make the same  in the asm source ,if you want.

[TimoVJL]

I have find it easy to translate (64),here the result
The translated is named firewall_asm.exe and the c sample firewallref.exe

It was C++ example, not C

wow, I am just looking at your github, this is impressive.  Is "Asmc" an assembler package for COM or something?  What does the acronym stand for?  You have alot of inc files.  Can I just use these in masm32?  I think I will play around with this tonight. Thank you good sir, cool.  I see rax register used.  I guess you are using 64bit, I am still using most things 32bit, will all this work with 32bit?
