send "1" or "0" to user32.DLL

[Darkxceed]

Hello all,

I have a simple question I think because Im new to autoit.

Still I have not found any clue on the internet how to do this.

My code is:

$dll = DllOpen("user32.dll")

$result = DllCall($dll, "int", "BlockInput") = 1

$result = DllCall($dll, "int", "BlockInput") = 0

DllClose($dll)

This gives an error when executed.

Please tell me why?

Btw i know autoit has the function(Blockinput(x)), but I want to know how to do this.

gr,

Bart

The correct format would be:

$dll = DllOpen("user32.dll")
$result = DllCall($dll, "BOOL", "BlockInput", "BOOL", 1)
If @error Then ConsoleWrite('error' & @error & @LF)
ConsoleWrite($result[0] & ' ' & _WinAPI_GetLastError() & @LF)

The call completes ok on my pc, but I get "ERROR_ACCESS_DENIED 5 (0x5)" Returned from _WinAPI_GetLastError(). Might still work for you if your using xp. I'm puzzled here.

Figured it out. I needed to have admin rights.

#Include <WinAPI.au3>
#requireadmin
$dll = DllOpen("user32.dll")
$result = DllCall($dll, "BOOL", "BlockInput", "BOOL", 1)
If @error Then ConsoleWrite('error' & @error & @LF)
ConsoleWrite($result[0] & ' ' & _WinAPI_GetLastError() & @LF)

Hi Beege,

thnx for the reply.

The example you gave did not work.

Getting "1 0" when executing.

So no error but my mouse did not freeze.

I tried:

$dll = DllOpen("user32.dll")

DllCall($dll, "BOOL", "BlockInput", "BOOL", 1)

But that gave errors.

on xp its working correctly

and its syntax is correct according to

did you add #requireadmin ?

Did you add a sleep() to the end of the script to verify your mouse didnt freeze? If you ran only what I posted it would blockinput, then exit immediately.

#Include <WinAPI.au3>
#requireadmin
$dll = DllOpen("user32.dll")
$result = DllCall($dll, "BOOL", "BlockInput", "BOOL", 1)
If @error Then ConsoleWrite('error' & @error & @LF)
ConsoleWrite($result[0] & ' ' & _WinAPI_GetLastError() & @LF)
sleep(10000)

Ah sorry, didnt know that after the script has executed it returns back to '0', thanks for the help and time!
