hey, i suggest downloading some of the old fasm versions with the link provided in said thread it is http://fasm.sourceforge.net/archive/

from like 1.04+ (i think?) it has alot of hardcoded windows examples, including export, procedures, even some resource stuff, i know it helped me alot!

All right, every thing ok, but I can't "export two procedures" from example dll. I have this code in export section (and the application cannot find the ShowLastError):

Code:

  dd 0,0,0,rva dlldemo_name,1
  dd 1,1,rva addresses_table,rva names_table,rva hints_table

  addresses_table:
    dd rva ShowErrorMessage
    dd rva ShowLastError
  names_table:
    dd rva _ShowErrorMessage
    dd rva _ShowLastError
  hints_table:
    dw 0

  dlldemo_name db 'ERRORMSG.DLL',0

  _ShowErrorMessage db 'ShowErrorMessage', 0
  _ShowLastError db 'ShowLastError', 0

The table called "hints" is in fact the table of ordinal numbers - indexes into the addresses table. Each item in table of ordinals corresponds to the item of the same index in the table of names.
Thus your export should look like:

Code:

  dd 0,0,0,rva dlldemo_name,1 
  dd 1,1,rva addresses_table,rva names_table,rva ordinals_table 

  addresses_table: 
    dd rva ShowErrorMessage ; index 0
    dd rva ShowLastError ; index 1
  names_table: 
    dd rva _ShowErrorMessage 
    dd rva _ShowLastError 
  ordinals_table: 
    dw 0 
    dw 1

  dlldemo_name db 'ERRORMSG.DLL',0 

  _ShowErrorMessage db 'ShowErrorMessage', 0 
  _ShowLastError db 'ShowLastError', 0

(and remember that table of names has to sorted alphabetically)
