_IsPressed Problem

[shmuelw1 1]

I'm trying to create a small script to press a few keys after two mouse clicks. Below is the script that I wrote. For some reason it does the Send command after only one click, then it waits until I click again.

#Include <Misc.au3> ; required for _IsPressed
$dll = DllOpen("user32.dll")
Dim $x = 0
 
While 1
  While $x < 2
    If _IsPressed("01", $dll) Or _IsPressed("02", $dll) Then
     $x = $x + 1
    EndIf
  WEnd
  Send("{UP 4}{ENTER}{ENTER}")
  $x = 0
WEnd

This version works after one click, and gives me 1 1/2 seconds to make the second click before calling the Send command. But I'd prefer to get AutoIt to wait for the second click without using the Sleep function. Any ideas?

While 1
    While 1
        If _IsPressed("01", $dll) Or _IsPressed("02", $dll) Then ExitLoop
    WEnd
    Sleep(1500)
    Send("{UP 4}{ENTER}{ENTER}")
WEnd

I expect it's because you only test to see if the button is pressed and it will loop round fast and get to a count of 2 before the button is released. You need to wait fo rth ebutton to be released before you check to see if it's pressed again.

Something like this maybe but I haven't tested it.

#include <Misc.au3> ; required for _IsPressed
$dll = DllOpen("user32.dll")
Dim $x = 0

While 1
    While $x < 2
        If _IsPressed("01", $dll) Then
             waittilnotpressed("01", $x)
        ElseIf _IsPressed("02", $dll) Then
            waittilnotpressed("02", $x)
        EndIf
    WEnd
    Send("{UP 4}{ENTER}{ENTER}")
    $x = 0
WEnd

Func waittilnotpressed($skey, ByRef $y)
    $y = $y + 1
    While _IsPressed($skey, $dll)
        Sleep(20)
    WEnd
EndFunc   ;==>waittilnotpressed

shmuelw1,

Sorry for the idiot response earlier. Testing and investigation indicate that this is, as Martin says, related to typematic rate and key bounce. One possible solution: low level keyboard handler and increment your counter at mouse up instead of mouse down. For example of LL keyboard handler see the help file or this thread
