Diegofeelsthenew,

Welcome to the AutoIt forum.

Your download site says the file is "temporarily unavailable".

Just post it directly - it is not very big according to the site. Put [autoit ] before and [/autoit ] after your code (but omit the trailing space - it is only there so the tags display here).

We cannot help if we cannot see what you have done.

Hello, greetings from chile, well my problem is with a script:

Func _LOCATION (ByRef $ iE, $ page = 1, $ state = "", $ city = "", $ country = "")

Local $ file, $ code, $ innerHTML, $ array [1]

local $ GLOBAL_ARRAY [1]

alert ("Going to the directory page" & $ page & "...")

_FileWriteLog ($ DEBUG_LOG_FILE, @ ScriptLineNumber & "->" & "Entering the http://fotolog.com/a/geo/SA?page url =" & $ page & "& state =" & _ $ STATE

& "& City =" & $ city & "& country =" & $ country)

If Not ie_navigate ($ iE, "http://geo.fotolog.com/SA?page =" & $ page & "& state =" & _ $ STATE

& "& City =" & $ city & "& country =" & $ country) Then

_FileWriteLog ($ DEBUG_LOG_FILE, @ ScriptLineNumber & "->" & "Could not load the http://fotolog.com/a/geo/SA?page url =" & $ page & "& state =" & _ $ STATE

& "& City =" & $ city & "& country =" & $ country)

_LOCATION ($ iE, $ page 1, $ state, $ city, $ country)

Return

EndIf

alert ("Scanning ...", 500)

$ InnerHTML = _IEPropertyGet ($ iE, "innerHTML")

$ InnerHTML = StringLower ($ innerHTML)

$ Array = StringRegExp ($ innerHTML "http://www.fotolog.com/ ([a-zA-Z0-9_] (1 ,})", 3)

; Searches for url matches

_addToGlobalPostArray ($ array, $ GLOBAL_POST_ARRAY)

; ~ Postea from the last remaining

, ~ Y can be edited in real time while running the program;)

For $ i = $ GLOBAL_POSTS_COUNT To UBound ($ GLOBAL_POST_ARRAY) - 1

_POST ($ iE, $ GLOBAL_POST_ARRAY [$ i], "http://www.fotolog.com/" & $ GLOBAL_POST_ARRAY [$ i])

$ GLOBAL_POSTS_COUNT = 1

Next

$ GLOBAL_ARRAY_COUNT = 1

_LOCATION ($ iE, $ page 1, $ state, $ city, $ country)

Return

ENDFUNC)

It works well but after a few minutes get a message that says: level has-been recurcion ecxeeded & $ page & "..."

I need help please: (

Diegofeelsthenew,

Recursion means that you are calling a function from within itself without the first instance ending.

Here you are doing exactly that with your _Location function - you are calling it from within itself. AutoIt allows you to do this a limited number of times before throwing an error.

Most coders avoid recursion like the plague if they can - for the very reasons you are discovering. Recursion can be useful, but you have to take extreme care to unwind all the function calls - and not exceed the total recursion limit set by AutoIt to avoid stack overflow.

I strongly suggest that you recast your code so that you allow the _Location function to return before you call it again with new parameters. One way of doing this is to use arrays to store any additonal parameters and then continue to call the function until the array is empty.

I hope this helps.

Most cowardly coders with no sense of adventure and challenge, anyway...

PsaltyDS,

Hmmmm.....

F**k recursion. I, apparently, am not ahead of the pack because I dislike and do not think recursively and thus would not use recursion to solve a real problem.

You sure about that?
