Winactivate breaks BlockinputEx and MouseTrap

Recommended Posts


The one has almost killed me. I have a program that when I use WinActivate it seems to break both _BlockInputEx and MouseTrap but doesn't really kill them. It is like a slow bleed. The mouse will work and the keyboard will work but very, very, very slowly. This is really stripped down for help purposes . What I am trying to do is (based on a number which changes in this loop) force a notepad document to the forefront even if a window like TaskManager is present with it's SetOnTop attribute set. The BlockInputEx and MouseTrap stay in effect until the notepad document test.txt is opened. It does force test.txt to the foreground but at that pound the Mouse and keyboard "bleed". I am desperate for some help! Here is the code:

#include <blockinputex.au3>

#include <constants.au3>

#include <winapi.au3>

Global $LenSpeedCursor = 18

Global $LastNumber = 0

Global $SpeedCursor = "Current number is "

Global $Debug = False

Global $ShowSpeed = "Yes"

Global $NumberLimit = 25

Global $ClearOnTop = "Yes"

Global $HerbieError = True

Global $CurrentNumber = 0

Global $FixedWindow = "Test.txt - Notepad"

HotKeySet("{ESC}", "Quit")

$CurrentNumber = 99

While 1

If $ShowSpeed = "Yes" Then

ToolTip($SpeedCursor & $CurrentNumber)



Case ($LastNumber <= $NumberLimit) And ($CurrentNumber > $NumberLimit) ; Number went from under limit to over limit

$LocalResult = _BlockInputEx(1, "{ESC}") ; block everything except esc

If $LocalResult = 0 Then

ConsoleWrite("BlockInput failed" & @CR)


$LocalResult = _MouseTrap(@DesktopWidth - 200, 10, @DesktopWidth - 199, 11); Move mouse out of way

If $LocalResult = 0 Then

ConsoleWrite("Error setting MouseTrap" & @CR)


TraySetState(4) ; Flash

Case ($LastNumber > $NumberLimit) and ($CurrentNumber > $NumberLimit) ; Number continues to be above limit



$LastNumber = $CurrentNumber



Func Quit()





Func CheckWindowPriorities()

Local $Result


$Result = WinActivate($FixedWindow, "")

ConsoleWrite("Attempt to activate " & $FixedWindow & " was " & $Result & @CR)


Func TurnOffOnTop()

Local $Index, $Result, $WindowList, $iExStyles = 0, $Candidate

$WindowList = WinList()

For $Index = 1 to $WindowList[0][0]

;ConsoleWrite($WindowList[$Index][0] & @CR)

$iExStyles = _WinAPI_GetWindowLong($WindowList[$Index][1],$GWL_EXSTYLE)

$Candidate = ($WindowList[$Index][0] <> "") And (IsWindowVisible($WindowList[$Index][1]))

$Candidate = $Candidate And (BitAND($iExStyles,$WS_EX_TOPMOST))

$Candidate = $Candidate And (StringLeft($WindowList[$Index][0], $LenSpeedCursor) <> $SpeedCursor)

If $Candidate = 1 Then

$Result = WinSetOnTop($WindowList[$Index][1], "", 0)

if $Debug = True Then

ConsoleWrite($WindowList[$Index][0] & " topmost set was: " & $SFResult[$Result] & @CR)




Func IsWindowVisible($WindowHandle)

If BitAnd( WinGetState($WindowHandle), 2 ) Then

Return 1


Return 0

Code tags would make that so much easier to read.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I was kind of hoping that since this is such a simple script that someone might copy the code and run it...

I agree with BrewManNH, code tags if you're posting AutoIt code please. I also wouldn't call what you posted as 'small', this is small...

I personally don't use that UDF, so my suggestion is start from scratch, creating a small reproducer and working from there. It might not be what you're looking for but it's how you learn to correctly debug your programs.
