I have a syntax error in an operation! Give me a tiny help, please!

10 posts in this topic

Hello! I have a "syntax error" but I can't understand where is it. Can you help me with this?

There is two text files. I want to write three lines of the first file in each line of the second file. Then, if the first file has 600 lines, the second file should have 200 lines.

I hope I have explained well what I want.

#include <File.au3>
Local $sFile1
$sFile1 = "File1.txt"
Local $sFile2
$sFile2 = "File2.txt"
Local $sThreeLinesIntoOne
FileOpen($sFile1,0)
FileOpen($sFile2,2)
For $i In ( _FileCountLines($sFile1) / 3 )
   For $a = ( ( $i - 1 ) * 3 ) + 1 ) To ( $i * 3 )
   $sThreeLinesIntoOne = $sThreeLinesIntoOne & FileReadLine($sFile1, $a)
   Next
FileWriteLine($sFile2, $sThreeLinesIntoOne)
Next
FileClose($sFile2)
FileClose($sFile1)

AutoIt returns:

error: syntax error
For $a = ( ( $i - 1 ) * 3 ) + 1 )

You missed an opening parentheses

For $a = ((( $i - 1 ) * 3 ) + 1 ) To ( $i * 3 )

 


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.

hahaha I was thinking that the error should be a tiny mistake... but my brain is out for today haha Thanks!

But now I have another error:

Variable must be of type "Object".:
For $i In ( ( _FileCountLines($sFile1) )  / 3 )

I didn't found the solution... and today I'm going to get crazy... sorry for my questions >.<

Variable must be of type "Object".:
For $i In ( (_FileCountLines($sFile1))  / 3 )
For $i In ( (_FileCountLines($sFile1))  / 3 )^ ERROR

Did you read HelpFIle TWICE , or more times ?
Why you are using   "For .. in ... next"    for   normal loop ?

 

btw.
your expression:

( (_FileCountLines($sFile1))  / 3 )

again missed one opening bracket.

( ((_FileCountLines($sFile1))  / 3 )

No, I didn't forget a parenthesis. You placed in your code four opening parentheses and three closing parentheses.

And yes, I have read the help file but I'm newbie on AutoIT, and I'm here to learn and improve my programing skill.

I haven't understood why it's wrong to use a "for" loop in my code, sorry!

Rhazz,

As explained in the Help file, you should only use the "For...In...Next" type of loop when dealing with a collection (an Object or an Array). In this case you are using an integer - and so you get an error, again explained in the Help file. Do it like this:

For $i = 1 To (_FileCountLines($sFile1) / 3 )

as the "For...To...Next" loop expects number bounds.

Yes, I had misunderstood that part :s

With "For...To..Next" it works, thanks!

I'm reading the Help File for all of the things that I want to do haha and sometimes I make stupid mistakes xD

      Hi all,
      I have a bit of code that works on my old Win10 PC, that fails on my new Win10 PC, and I think the only significant difference is the version of Autoit - old PC has 3.3.12, new has 3.3.14.
      I couldn't find anything mentioned in the change logs though, so perhaps I'm wrong.
      Anyway, the code to replicate my issue is:
      Test('username', 'DOMAIN') ; THIS ERRORS: ;Test('localun', 'DOMAIN') ; THIS ERRORS: ;Test(' ', ' ') ; THIS ERRORS: ;Test('', '') ; THIS ERRORS: ;Test('localun', '') ; THIS ERRORS: ;Test('', 'DOMAIN') Func Test($un, $dom) $compName = 'PCNAME' $FullName = '.' $Description = '.' ; get the WIM object $objWMIService = ObjGet("winmgmts:\\" & $compName & "\root\cimv2") ; get default user full name and description $objAccount = $objWMIService.Get("Win32_UserAccount.Name='" & $un & "',Domain='" & $dom & "'") If IsObj($objAccount) Then $FullName = $objAccount.FullName $Description = $objAccount.Description EndIf ConsoleWrite($FullName & @CRLF) ConsoleWrite($Description & @CRLF) Return EndFunc  
      On my old PC this code will output just . and . for each of those line currently commented out. Which is fine.
      On my new PC any of those commented out lines of code cause an error, and the script won't even compile.
      $objAccount = $objWMIService.Get("Win32_UserAccount.Name='" & $un & "',Domain='" & $dom & "'") $objAccount = $objWMIService^ ERROR I'm very much a newb with the WMI stuff and objects, but it looks like the .Get property is failing when either $un or $dom aren't valid in v3.3.14, whereas in 3.3.12 the .Get would fail to return an object, which is then caught by the If statement.
      Am I on track with this? Is there some new/better way to code the example so that 3.3.14 will compile it?

      Hey everyone,
      I've been messing around with some new things and adlibs look extremely useful/interesting, however, I can't seem to get it to work.. Here's what I have
      HotKeySet("{F1}", "_Exit") $qCount = 1 Global $_Timer AdlibRegister($_Timer, 1000) AdlibUnRegister($_Timer) While 1 SoundPlay(@WindowsDir & "\media\tada.wav", 1) $qCount += 1 ToolTip('"Tada" has been played ' & $qCount & " times",200,200) WEnd Func _Timer() Local Static $iCount += 1 ConsoleWrite($iCount) If $iCount = 20 Then ConsoleWrite("iCount is at " & $iCount) EndFunc Func _Exit() Exit EndFunc Basically I want it to call the _Timer function but it doesn't seem to work :/ any ideas?

      Try to find a solution for help files to my autoit executable.
      Its installed from simple XP-POS cash computers to desktop with windows 7, 8, 10.
      The compiled AutoIt program itself work everywhere, but the help file??
      I need a help file called from from the program and I don't really know what working best in all OS platforms.
      1. A wordfile is helpful enough, but word is not installed everywhere.
      2. RTF is very big files with pictures.
      3. I could save it as pdf, but not all have it either.
      4. Tried  .MHT file, but downside is browser could cover hole screen if browser closed this way. I have not found any way to resize it to specific size when open up.
      5. Use of IE.au3 lib. Well it could open mht files ,but always got question about use it as default browser or not. Think this also make IE browser lose control so I could not resize.
      6. Look at making a  .CHM file, but I don't think its the future do use that format. (.hlp is no no and old)

      Any tips of do it in autoit or make a call to open up in some nice format working everywhere.

      Hellow everybody,
      I tryed to manipulate a game called "Assault Cube" which is a easy beginning in coding. I run the code but the wished value doesn't change, i don't understand why.
      The Pointers are fine, I checked that the pointers don't change every time while restart the game.
