Need help with GetLastInputInfo via System Plugin

Hi. I'm trying to get the GETLASTINFO structure from GetLastInputInfo function from user32.dll

here's my current code:

System::Alloc 32

Pop $1

# call

System::Call "user32::GetLastInputInfo(p r1)"

# get

System::Call "*$1(&l, i.r0)"

MessageBox MB_OK "$0"

# free

System::Free $1

this code crashes... not sure what the problem is.

I'd very much appreciate you guys taking a look @ it and offering some assistance.

Thanks!

I Think the problem may be that I need to set the first member of the struct in $1 to sizeof(struct) (by using &l, correct?) however, I do not know how to set the members of a struct with nsis.

p type does not work in 2.46, use i

thank you.

Now it doesn't crash, but it just has one output for the second member of the struct (milliseconds since last input)...

${While} 1 == 1

System::Alloc 32

Pop $1

System::Call "*$1(&l, i.r0)" ;setting data in struct..

System::Call "user32::GetLastInputInfo(i r1)" ;call function..

# get

System::Call "*$1(&l, i.r0)" ;read struct output

DetailPrint "$0"

System::Free $1

${EndWhile}

note: it's in an inf. while loop so I can see if the time since last input values will change of course

it just constantly stays at zero regardless if my activity

do you see any reason why this will happen?

hmm,

when I replace line 4 in my code with this:

System::Call "*$1(&l, i 5)" ;setting data in struct..

then the "output" will just stay at 5... so it seems like GetLastInputInfo isn't manipulating the struct at all...

System::Call '*(i 8,i)i.r0'
System::Call 'USER32::GetLastInputInfo(ir0)'
System::Call '*$0(i,i.r1)'
System::Free $0
DetailPrint $1

...

Not sure how you are supposed to use &l but this works without it:

System::Call `*(i 8, i 0) i.r0`

System::Call `user32::GetLastInputInfo(i r0)`

System::Call `*$0(i, i.r1)`

System::Free $0

DetailPrint $1

Edit: LOL^ 😁

So awesome. Thanks guys.
