IMPORTANT:
There is a bug in comctl32.inc file of FASMW.

It must be:

Code:

struc TBBUTTON
 {
   .iBitmap   dd ?
   .idCommand dd ?
   .fsState   db ?
   .fsStyle   db ?
   .resword   dw ? ; reserved for dword alignment
   .dwData    dd ?
   .iString   dd ?
 }

This leads to wrong work with .dwData and .iString fields.

Strange, but Win32 Help said me that version of structure in comctl32.inc is right...

In C compiler, they help you align to dword. Now with assembler you need to do it yourself.

Even in masm it looks like

Code:

TBBUTTON STRUCT
  iBitmap           DWORD      ?
  idCommand         DWORD      ?
  fsState           BYTE       ?
  fsStyle           BYTE       ?
  _wPad1            WORD       ?
  dwData            DWORD      ?
  iString           DWORD      ?
TBBUTTON ENDS
