Hi friends,

You can add compiled resource scripts to the executables assembled with
Fasm.The method is based on using a free resource linker (6.5Kb.)
from the Sphinx C-- website.

1)First,you add an "empty" resource section to the end of your source
file,this provides enough room for the resource section in the PE
object table:
Code:
section '.rsrc' resource data readable
    


2)Assemble the source file.
3)You delete the resource section body and add the compiled resource
file(.res) to the executable.This trick of "removing the resource section"
is required;otherwise the executable will not run on Win XP:
Code:
rl menu.exe /d
rl menu.exe rsrc.res /a
    


The advantage of this method that you can use directly all your resource
scripts with Fasm,just enough to have the final compiled resource file
(.res)
Another advantage;you don't need of .obj files.

A very usefull and free resource editor available from Hutch's homepage:

Great. And this method can improved to make it easy for using with fasmw:

1. Make one exe using method above
2. Rename exe as 'dummy.exe'
3. Use tdump (for example) to know offset and size of .res section
4. Then write in your source:
Code:
section '.rsrc' resource data readable
file 'dummy.exe': 800h, 200h ; see file syntax and put actual values

I just put the blank resource section to the last and use ResourceEditor and PEditor to edit (easy to expand in the future).

Aquila: that might not work because resource data contains some RVA addresses and these can be changed when you place your resource section in some other place of file.

Aquila,

Have you tried Resource Hacker?

Quote:

Resource Hacker is a freeware utility to view, modify, rename, add, delete and extract resources in 32bit Windows executables and resource files (*.res). It incorporates an internal resource script compiler and decompiler and works on Win95, Win98, WinME, WinNT, Win2000 and WinXP operating systems.

Hi friends,

Another method of embedding resources is to read binary resource data bytes from a .res file. This is equivalent to a dialog box template in memory.
Code:
pDlgbox FILE 'Rsrc.res' : 50h ;Skip the header to read directly binary resource data
    


This trick appears to be O.K for simple dialog box resources.

Without the resource section, the size of the final executable drops down by 512 bytes.
