The most useless UDF ever.

[w0uter]

well yeah the title says it all. :">

Func _Ret($v_return)
    Return $v_return
EndFunc

[Insolence]

LOL.

Well done!

[CyberSlug]

I wonder: In case the user passes a function to _Ret, it might be better to say:

Func _Ret($v_return)
    Local $result = $v_return
    SetError(@error)
    Return $result
EndFunc

[Insolence]

Amazing, that's perfect! Exactly what I needed!

[Insolence]

Or maybe even:

Func Useless()
EndFunc

[layer]

at least it returns an expected result... but, this is useless

Func CurrentTime()
   Return Random()
EndFunc

<{POST_SNAPBACK}>

lol...

I could see it now: "EDIT: added UDF _Ret" in the dev section

[bluebearr]

Hmmm, this function is worse than useless:

Func _Ret($v_return)
    Local $result = $v_return
    SetError(@error)
        For $j = 1 to 10000
            For $i = 1 to 100000
                $A = StringSplit(Random(), "")
            Next
        Next
    Return $result
EndFunc

The inner loop takes ~6 seconds, so maybe the outer loop will take 60000 secs which is over 16 hrs? What fun!

Thats not actually sytactically valid so its not a function.

Neither is this

If that was valid it could accually have a use so it wouldnt be useless.

Its just a fancy way of closing your script

There is no need of thinking about useless scripts, just use the seach button.

I think Bluebearr had the right idea, but what that script really needed was a way to keep the user from killing it. You need to use the progress bar with percent display include with this one, but it displays a progress bar where every percent takes longer than the previous one.

Not useless. Off the top of my head, I can see that calling that function does at least three things:

Clears @Error

Clears @Extended

Verifies that AutoIt is not at it's maximum recursion level

And if you're still using v3.1.1.0, this will clear the return value which is a bug (Fixed in beta). For example, if you returned a large array (Bad idea, always work on arrays ByRef to avoid copying), then there would be two copies of the large array in memory; one in the variable holding the array and one erroneously sitll stored in the internal variable that holds the Return value. Calling an empty function would clear that return value and free the memory.

Again, that only affects v3.1.1.0 and older; its fixed in the beta.

Not exactly useless, just a really inefficient "Pause" function...

[mother9987]

I changed mine a little bit.

$progress[99] = $iterations
    For $i = 98 to 0 Step -1
        $progress[$i] = $progress[$i + 1] / 1.15
    Next

1.15 seems to make me hate life a lot more than 1.3. I'm convinced that a lot of installers are using this kind of exponential for their progress bars already.

Seems to me it's not useless at all, it keep you busy
