Home » Forums » MAIN » windows.inc struct question

the currect windows.inc struct im having problems with looks like this.

NMRBAUTOSIZE STRUCT
  hdr       NMHDR      <>
  fChanged  DWORD      ?
  rcTarget  RECT       <>
  rcActual  RECT       <>
NMRBAUTOSIZE ENDS

i convert it to this but i get redefinition errors.

NMRBAUTOSIZE STRUCT
STRUCT
  hwndFrom  DWORD       ?
  idFrom    DWORD       ?
  code      DWORD       ?
ENDS
  fChanged  DWORD       ?
STRUCT
  left      dd          ?
  top       dd          ?
  right     dd          ?
  bottom    dd          ?
ENDS
STRUCT
  left      dd          ?
  top       dd          ?
  right     dd          ?
  bottom    dd          ?
ENDS
NMRBAUTOSIZE ENDS

the problem is i have 2 structures that are exactly the same. i need to know how i can name them or change them somehow so i dont get the errors. of course it needs to work properly after the modifications. i tried using changing it to:

NMRBAUTOSIZE STRUCT
STRUCT
  hwndFrom  DWORD       ?
  idFrom    DWORD       ?
  code      DWORD       ?
ENDS
  fChanged  DWORD       ?
@tag_1 STRUCT
  left      dd          ?
  top       dd          ?
  right     dd          ?
  bottom    dd          ?
@tag_1 ENDS
@tag_2 STRUCT
  left      dd          ?
  top       dd          ?
  right     dd          ?
  bottom    dd          ?
@tag2 ENDS
NMRBAUTOSIZE ENDS

but i still get errors. thanks smurf This message was edited by smurf, on 5/4/2001 1:20:05 AM This message was edited by smurf, on 5/4/2001 2:10:19 AM

windows.inc struct question

It doesn't work like that, but you already noticed :rolleyes: Inside a structure, you can't place another STRUCT. This isn't needed because you can do any data declartion in the first struct. Anyway, this how the structure is accessed as in windows.inc: (say you declared

mystruct   NMBRAUTOSIZE

)


mystruct.hdr.hwndFrom
mystruct.hdr.idFrom
mystruct.hdr.code
mystruct.fChanged
mystruct.rcTarget.left
mystruct.rcTarget.top
mystruct.rcTarget.right
mystruct.rcTarget.bottom
mystruct.rcActual.left
mystruct.rcActual.top
mystruct.rcActual.right
mystruct.rcActual.bottom

Study that, and you'll understand how to make what you're trying to do work.

windows.inc struct question

Smurf, The main structure below looks OK, the trick is how to expand it in your code.


    NMRBAUTOSIZE STRUCT
      hdr       NMHDR      <>
      fChanged  DWORD      ?
      rcTarget  RECT       <>
      rcActual  RECT       <>
    NMRBAUTOSIZE ENDS

In a proc,


    LOCAL nas:NMRBAUTOSIZE

    mov nas.hdr.hwndFrom,    0
    mov nas.hdr.idFrom,      0
    mov nas.hdr.code,        0
    mov nas.fChanged,        0
    mov nas.rcTarget.left,   0
    mov nas.rcTarget.top,    0
    mov nas.rcTarget.right,  0
    mov nas.rcTarget.bottom, 0
    mov nas.rcActual.left,   0
    mov nas.rcActual.top,    0
    mov nas.rcActual.right,  0
    mov nas.rcActual.bottom, 0

This is the fully expanded form of the structure initialised to zero, if you need to put memory operands into the members, you will have to either use a register for each one or use push/pop. Regards, hutch@pbq.com.au
