in this example you have to specify each funcion that you import. See the last lines of this file:

Code:

  import user,\
         RegisterClass,'RegisterClassA',\
         CreateWindowEx,'CreateWindowExA',\
(and so on...)

If you want to use CloseWindow API, you have to add this function there:

Code:

  import user,\
         RegisterClass,'RegisterClassA',\
         CreateWindowEx,'CreateWindowExA',\
         CloseWindow,'CloseWindow',\                ;  <----
         DefWindowProc,'DefWindowProcA',\
         GetMessage,'GetMessageA',\
         TranslateMessage,'TranslateMessage',\
         DispatchMessage,'DispatchMessageA',\
         LoadCursor,'LoadCursorA',\
         LoadIcon,'LoadIconA',\
         PostQuitMessage,'PostQuitMessage'

Remember that FASM is case-sensitive so you when you declare import like above, instead of

Code:

invoke closewindow,eax

you have to use

Code:

invoke CloseWindow,eax

Also, you don't have to add your imports manually. The import section can look like this:

Code:

section '.idata' import data readable writeable
  library kernel,'KERNEL32.DLL',\
          user,'USER32.DLL'

  include '%fasminc%/apia/kenrel32.inc'
  include '%fasminc%/apia/user32.inc'

... and you will have all functions from kernel.dll and user.dll available.
