Title: Conditional assembly problem

Hi Jeremy,

I am having trouble with the exact syntax to get this structure working under the new headers OS ID scheme...

Code Select

// just to have a value we'll set GUID to a DWORD
#DEFINE HANDLE DD
#DEFINE GUID DD

#define NTDDI_WIN9X                         0x03000000
#define NTDDI_WINNT4                        0x04000000
#define NTDDI_WIN2K                         0x05000000
#define NTDDI_WINXP                         0x05010000
#define NTDDI_VISTA                         0x06000000
WINVER = NTDDI_VISTA

XNOTIFYICONDATAA STRUCT
	cbSize DD
	hWnd HANDLE
	uID DD
	uFlags DD
	uCallbackMessage DD
	hIcon HANDLE
	#IF WINVER < NTDDI_WIN2K
		szTip DB 64 DUP
	#ENDIF

	#IF WINVER >= NTDDI_WINN2K
		szTip DB 128 DUP
		dwState DD
		dwStateMask DD
		szInfo DB 256 DUP
		UNION
			uTimeout DD
			uVersion DD
		ENDUNION
		szInfoTitle DB 64 DUP
		dwInfoFlags DD
	#ENDIF

	#IF WINVER >= NTDDI_WINNXP
		guidItem GUID
	#ENDIF

	#IF WINVER >= NTDDI_VISTA
		hBalloonIcon HANDLE
	#ENDIF
ENDS

When (as above) NTDDI_VISTA is defined the member hBalloonIcon should be available however everything past the first #IF is ignored or at least seems to be. Changing the WINVER to WIN2K or above will not display szTip.

Using WINVER = NTDDI_WIN2K

Code Select

Inappropriate or missing operand to the mnemonic
mov eax,XNOTIFYICONDATAA.szTip

EDIT:

It appears to be the >= operator that is causing the problem, using simple > seems to work...

Code Select

#define NTDDI_WS03MAX			0x0502FFFF
#define NTDDI_WIN2KMAX                      0x0500FFFF

XNOTIFYICONDATAA STRUCT
	cbSize DD
	hWnd HANDLE
	uID DD
	uFlags DD
	uCallbackMessage DD
	hIcon HANDLE
	#IF WINVER < NTDDI_WIN2K
		szTip DB 64 DUP
	#ENDIF

	#IF WINVER > NTDDI_WINNT4
		szTip DB 128 DUP
		dwState DD
		dwStateMask DD
		szInfo DB 256 DUP
		UNION
			uTimeout DD
			uVersion DD
		ENDUNION
		szInfoTitle DB 64 DUP
		dwInfoFlags DD
	#ENDIF

	#IF WINVER > NTDDI_WIN2KMAX
		guidItem GUID
	#ENDIF

	#IF WINVER > NTDDI_WS03MAX
		hBalloonIcon HANDLE
	#ENDIF
ENDS

Edgar

When declaring this structure I got the message:-

QuoteCould not evaluate expression in conditional directive:-
NTDDI_WINN2K

The expression has two N's instead of one, which may be your problem.

I see that you get a much less informative error message.
This seems to be because you are not actually declaring the structure but merely using it to establish an offset from one place to another.
I'll look into whether I can improve on this error message and come back to you.

Thanks Jeremy,

Don't know how many times I looked at that and didn't see the 2 double N's. All is good !

I've improved the error messages when conditional assembly goes wrong inside structs when not declaring the struct, but merely using it to find the distance from one place to another, in GoAsm Version 0.56.5e (attached).
