Hello everybody,

I'm desperate, I'm trying to do my first AutoIt script to uninstall Symantec products from my consumer's computer stations. I take sample from this forum, that seems nice and easy. Well go on.

But I've ever got compilation errors, I don't understand where is the mistake. Aut2exe only returns compilation error code 65535, nice the size of a short integer, but this doesn't help me.

Could you please help me ?

Func RegUninstallStringFind($szFind)
    Local $index, $subkey, $sRet, $sBuff
    Local Const $HKLM_UNINSTALL = "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall"
    $sRet = ""
    $index = 1
    While 1
        $subkey = RegEnumKey($HKLM_UNINSTALL, $index)
        If @error Then ExitLoop
        $sBuff = RegRead($HKLM_UNINSTALL & "\" & $subkey, "DisplayName")
        If StringInStr($sBuff, $szFind) Then
            $sRet = RegRead($HKLM_UNINSTALL & "\" & $subkey, "UninstallString")
            ExitLoop
        EndIf
        $index = $index + 1
    WEnd
    Return $sRet
EndFunc  ;==>RegUninstallStringFind

$a = ""
; change the search string accordingly
$a = RegUninstallStringFind("Symantec AntiVirus") 
If $a <> "" Then
    Local $cmd
    $cmd = StringReplace( $a, "/I", "/norestart /qn /x" )
    $cmd &= " REMOVE=ALL"
    ; this is just a test line to make sure it works
    MsgBox(0, "", "This is your uninstall command:" & $a)   
EndIf

Is there a way to get more informations about compilation mistake ?

and another... StringInStr returns a position (integer), not a boolean

That's not a syntax error in AutoIt: 
If StringInStr($sBuff, $szFind) Then

AutoIt does not use strong typing of variables. It will make some attempt to convert types. If the test string is not present StringInStr() returns 0, else it returns an integer position. Since on Boolean compare 0=False and all other numbers=True, this is a valid test if string $szFind is present in $sBuff.

Many thanks ctyankeeinok, it seems to work fine :)

wolf9228, I'm using ScieTE Script Editor but it doesn't return any usefull informations. I'm used to work with many programming languages and this is the first I see a so silent compiler :)

The code in the OP compiles and runs correctly for me on both the current production and beta versions. What are you running it on, and with what version of AutoIt?

Yes, correct information

But the logic operation is also correct

Failure: Returns 0 / False

Success: Returns the position of the substring

position Starts from one to infinity / True

Compiler doesn't return version in the about, but I've download it 3 days ago, so this is the last stable version 3, and it's running on Vista. But don't mind, it works well, I understand troubles, I've got this last days.

I still don't see how it would work properly with the missing EndIf.

The EndIf is not missing in the actual code. I only quoted the line with the Boolean compare in it.

It can also be correct to have If without EndIf, but only if it's a complete one-line statement with the conditional action on the same line. For example: 

If $n = 1 Then
     $s = "One"
EndIf

; Can be replaced with:
If $n = 1 Then $s = "One"

Edit: Looks like PsaltyDS beat me to it :)

PSaltyDS - Thanks for the correction/clarification on the boolean - I learned a new thing. I still don't see how it would work properly with the missing EndIf.

If your statement moves on to only a single line of code, you can place "Then ..." all on the same line and exclude the EndIf. I believe this is only for shortening your code. I'm not sure if it changes the performance of the script. For example, these two mean the same thing and both compile fine in AutoIt

If $var = 1 Then Return True

If $var = 1 Then
    Return True
EndIf

If the statement moves on to more than one line of code, then you cannot place it all on the same line and you must use EndIf.

If $var = 1 Then
    $var = 0
    Return True
EndIf

The following will give you a syntax error:

If $var = 1 Then Return True
EndIf

Well, it doesn't want to compile again, I've only done little changes :)

Func RegUninstallStringFind($szFind)
    Local $index, $subkey, $sRet, $sBuff
    Local Const $HKLM_UNINSTALL = "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall"
    $sRet = ""
    $index = 1
    While 1
        $subkey = RegEnumKey($HKLM_UNINSTALL, $index)
        If @error Then 
            ExitLoop 
        EndIf
        $sBuff = RegRead($HKLM_UNINSTALL & "\" & $subkey, "DisplayName")
        If StringInStr($sBuff, $szFind) Then
            $sRet = RegRead($HKLM_UNINSTALL & "\" & $subkey, "UninstallString")
            ExitLoop
        EndIf
        $index = $index + 1
    WEnd
    Return $sRet
EndFunc  ;==>RegUninstallStringFind

$a = ""
; change the search string accordingly
$a = RegUninstallStringFind("Symantec AntiVirus") 
If $a <> "" Then
    Local $cmd
    $cmd = StringReplace( $a, "/I", "/norestart /qn /x" )
    $cmd &= " REMOVE=ALL"
    ; this is just a test line to make sure it works
    MsgBox(0, "", "This is your uninstall command:" & $cmd)   
EndIf

I can't play longer with AutoIt, it seems there are a real problem and I can't work without error messages.

In my mind, there is no professionnal issue with AutoIt Don't mind about me, I'm rewriting script in Perl, I can't spend more time, my consumer waiting for application deploy.

Thanks for all your replies. AutoIt is on a good way, but no enough improve like Perl, OCaml, Lisp or VB, which are used from long time.

No one has yet reproduced your symptoms with the code you have posted. It's not AutoIt, just your broken AutoIt install or Windows environment. I doubt Perl works any better with a broken install...
