'Hello world'

someone gave winmm.inc but impossible to use with winax.inc

For example,

include 'x:\fasm\include\win32ax.inc'
include 'x:\fasm\include\api\winmm.inc'

.code
start:
invoke MessageBox,0,'something','something',MB_OK
invoke mciSendString 'open cdaudio',0,0,0
invoke ExitProcess,0
.end start

Fasm told me undenied symbol mciSendString ?

Can you help me ?
Advance thanks

You will need to have the winmm imports put into the .end macro. Just make a new .end macro modified as shown below.

Code:

;...
     library kernel32,'KERNEL32.DLL',\
             user32,'USER32.DLL',\
             gdi32,'GDI32.DLL',\
             advapi32,'ADVAPI32.DLL',\
             comctl32,'COMCTL32.DLL',\
             comdlg32,'COMDLG32.DLL',\
             shell32,'SHELL32.DLL',\
             wsock32,'WSOCK32.DLL'
----> add your winmm DLL link here

     import_kernel32
     import_user32
     import_gdi32
     import_advapi32
     import_comctl32
     import_comdlg32
     import_shell32
     import_wsock32
----> add your minmm imports here

;...

Fasm says now : illegal instruction import_winmm ...

If you haven't defined the macro 'import_winmm' then you can manually place the imports:

Code:

import winmm32,\ ;<--- use the same name you used for the library
       mciSendStringA,'mciSendStringA',\
       mciSendStringW,'mciSendStringW'
;...

Note the A and W versions for most Windows APIs that have text strings. You can also just put "mciSendString,'mciSendStringA'" if you only want to support ASCII.

Still have the same error message...
