Hello,
for checking the time of using my tools i use getsystemtime and then cmp ...,offset month
if the time i set in .data is true ,the program should not work.
but i dont understand why it works with :
cmp .... , 01 [01-is january]
and not when i use :
.data
month db '01' ,0
.code
getsystemtime......
cmp ... ,offset month
any ideas how i get it working ?
thx
When you declare month in data, you are declaring a "series" of bytes (as many as are needed to hold the specified data. In your case 3 bytes one for "0", one for "1", and a final one for your null terminator.
You are then comparing your retrieved value (a word presumably) against the address where these 3 bytes are stored!
What you need to do is the following:
invoke GetSystemTime, ADDR SysTime
cmp SysTime.wMonth, 1
;---- Or ----
.data
Month dw 1
.
.
.
invoke GetSystemTime, ADDR SysTime
mov ax, SysTime.wMonth
cmp ax, Month
Yep.. what Mirno said is right... I just felt like sthg was
missing:
Jeronimo:
If you declare
Month db "01",0"01",0 30 31 00Hello,
so there goes my problem,many thanks for the good help !
btw. did you have any good idea how i can make my tool working a small amount of time.
like trial software.
i think on some different ways like:
check systemtime
check time from different files
make a decrypted regkey who count the program start
is it today possible to make trial software who cant cracked ?
thanks
Everything can be cracked!
