Reset value if value is static?

[WiiDSmoker]

I hope I can explain this right.

Basically want I'd like to do, is, if a value I am reading doesn't change within one second then reset that value..

so for instance if the $value = 100, then after 1 second, if $value=100 STILL, then change $value to equal 0

 

can't seem to figure it out, seems like it would be easy though =/

Look at If statements in the help.

There's probably a couple of dozen ways of going about doing this, but without seeing how the value might be changed or where the variable is in the code it would be extremely difficult to give a good method of doing it that would work in the script you're working on. 

 

IOW, post what you have, even if it doesn't work the way you want it to, and show us what you need.

Basically I am reading in a value

$BoxTimer = _MemoryRead, etc

sometimes this time appears to get stuck

so if $BoxTimer does not change after one second, then reset $BoxTimer...

 

if $BoxTimer = 100, then one second later, if it equals 100 still, change $BoxTimer to zero

 

i dont know how else to explain 

[0xdefea7]

$BoxTimer = 100
AdlibRegister("_Changed", 1000)

Func _Changed()
    If $BoxTimer = 100 Then
        ;Report or do something
        $BoxTimer = 0
    EndIf
EndFunc

LOL. I just woke up.....        I suppose my script would NOT have worked...          Don't mind me, I'm getting coffee now.

 

0xdefea7,

You might want to look at the Not Var = Something line.

Thanks so much guys

0xdefea7,

I meant If Not (Var = Something) Then. You were missing the parenthesis around the expression.

I have never used parenthesis when using "Not" in my scripts. Is that just a good practice thing? The script as I posted it will run and compile in my version of SciTE without parenthesis.

[guinness]

You haven't!!! I can't think of a reproducer for the error, but there is one of using Not without parenthesis.

#include <Constants.au3>

Local $vVar = 'SomeTest'
; This expression before Then is Not True, as $vVar = 'SomeTest' evaluates to True, hence Not True.
If Not ($vVar = 'SomeTest') Then MsgBox($MB_SYSTEMMODAL, '1', 'This MsgBox won''t display, as $vVar = SomeTest.')
; AutoIt looks at this as (Not $vVar) = 'SomeTest'.
If Not $vVar = 'SomeTest' Then MsgBox($MB_SYSTEMMODAL, '2', 'This MsgBox won''t display, as $vVar = SomeTest.')

It has no sense to use the Not keyword for strings, better only use equal or different. You won't have to think about parenthesis unless you are using And/Or keywords in the same expression.

Edit: As far as I'm concerned, the Not keyword is the replacement of "= False" and nothing else.

Local $blTest = False

If Not $blTest Then
;or
If $blTest = False Then

Here is a video of your same example script in action on my PC:

This would be better :

#include <Constants.au3>

Local $vVar = 'SomeTest'
; This expression before Then is Not True, as $vVar = 'SomeTest' evaluates to True, hence Not True.
If Not ($vVar = 'SomeTest1') Then MsgBox($MB_SYSTEMMODAL, '1', 'This MsgBox won''t display, as $vVar = SomeTest.')
; AutoIt looks at this as (Not $vVar) = 'SomeTest'.
If Not $vVar = 'SomeTest1' Then MsgBox($MB_SYSTEMMODAL, '2', 'This MsgBox won''t display, as $vVar = SomeTest.')

[guinness]

Thanks for the video. I expected that, as I said I couldn't think of an example where it wouldn't work right. But others will tell you that best practice is to wrap the expression in parenthesis.

Thanks. That's it.

Indeed. Good example FireFox. It does work as expected now. TIL about Not. Thanks both of you
