I try to declare, in the .data section, a variable pdf, of type DATETIME, initialized with 0.
I receive the error : "index.asm(24) : Error A2233: Syntax error: pdt"
What I'm doing wrong?
This is the code:
.686
.model flat, stdcall
option casemap :none
include \masm32\include\masm32rt.inc
include \masm32\include\windows.inc
include \masm32\include\kernel32.inc

.data
pdt DATETIME 1 dup (0)
.code
start:
main proc
; INVOKE GetLocalDateTime, addr pdt
; INVOKE Day, addr pdt
exit
main endp
end start
.data
DATETIME TYPEDEF QWORD ; A DATETIME is a FILETIME in disguise
pdt DATETIME 1 dup (0)
The code you gave me worked perfectly. Thank you!
I saw that you defined the data type inside the .data section. Is it the same as declaring in an include file? I tried including
include \masm32\datetime\DateTime.incinstead of defining the type, and it worked, but does it have the same effect on the final code?

If I try this:
.data
; DATETIME TYPEDEF QWORD ; A DATETIME is a FILETIME in disguise
pdt FILETIME 1 dup (0)I receive this error message:
index.asm(25) : Error A2253: Structure improperly initialized: FILETIMEWhy?
Sergiu,
You have an include file duplication in your post, the masm32rt.inc already has files that you list below it and you are trying to include them twice. Either use it by itself or only add files after it that it does not contain.
structs must be initialized using angle brackets:
pdt FILETIME 1 dup (<0>)

Where did you find the definition of FILETIME? I searched \masm32, and I only found only 1 file that contains the FILETIME word in it.
\masm32\examples\exampl06\jacts\jacts.asm
I searched by this criteria "find all files, no matter the extension, that contain the word FILETIME".
So, am I to understand that FILETIME is a structure of strings, while DATETIME is made of 4 Words in a row? You're using angle brackets, therefore I assume that 0 is a string and not a number. "A DATETIME is a FILETIME in disguise", as mentioned in the file DateTime.chm is just a figure of speech?

Yes, it's the same. But, you should use
DateTime.inc when using the DateTime library. A DATETIME data type is equivalent to a QWORD. The FILETIME structure is the same size as a QWORD. This is done to avoid having to address the high and low DWORDs of the FILETIME structure.
And like Hutch said try to avoid multiple declarations and definitions,
masm32rt.inc is intended to replace several include files. Take a look at
masm32rt.inc in a text editor. By the way,
DateTime.inc is not included in
masm32rt.inc.

My bad. I cleaned the code after he told me so, but I didn't write here the cleaned version.
Everything is clear now, except for the FILETIME.
1. In what file is FILETIME defined?
2. What did you mean by:

No, a FILETIME is a structure of 2 DWORDS and a DATETIME is actually a QWORD. Look up FILETIME on MSDN. It's defined in
windows.inc in masm32.

In the code, it's a comment. In
DateTime.chm it's an explanation.
Don't use FILETIME in your code, use DATETIME if you are using the library.

Using a QWORD instead of a FILETIME is a way of simplifying Date and Time math.
Look at the code for the DateTime library.

NO, you understand WRONGLY.
Structures MUST be initialized by using angle brackets. This is the syntax for initaializing an STRUCT in MASM.
Inside < > you can place initial values to be placed in the structure's fields or "?" for unknown or non initialized fields. They are to be considered as numbers or strings or STRUCT's or typedefs or whatever other types depending on the STRUCT definition.
