Hi,
this might work!

Win32, invoke stdcall routine:

Code: [Select]

%macro invoke 1-*

%assign max %0 - 1

%if max > 0

%rotate max

%rep max

%warning %1

push %1

%rotate -1
%endrep

%endif

call %1
%endmacro

I suggest using NASMX,
because in win32 there is an 'N' various calling conventions,
which NASMX has worked out.

What part is too complex?  As the current NASMX lead designer I'm very interested in where you get stuck.  NASMX should be very familiar to Masm users.

As encryptor256 points out NASMX has already worked through all the issues you're likely to encounter when writing code.  At your level I don't recommend attempting to read through the macro definitions themselves as they are rather complex but rather simply use them until you become more comfortable.

Check out nasmx/demos/win32/ and start with DEMO1.  Each directory has a small example which shows you how to achieve what you're attempting.
