while loop times out?

[huskies 0]

Sometimes if this while loop have to run for more than 2 minutes,the programs gets stuck. As in my next step never gets ran. but for regular situation (around 10 seconds, it runs perfectly), so do while loops in Autoit time out after a while?

$file = fileopen($PuttyLogpath,0)

Local $str = FileReadLine($file, -1)

while $str <> $Message

sleep(200)

$str = FileReadLine($file, -1)

WEnd

You need to test the success of filereadline and act on it in case of EOF.

huskies,

do while loops in Autoit time out after a while?

No.

By the way, I am none too sure that you will ever get out of your loop as you might be locking the file when you open it and so it can never be re-read.

I found that this worked better:

$Message = "End"

$file = "test.txt"

Local $str = FileReadLine($file, -1)

While $str <> $Message
    Sleep(200)
    $str = FileReadLine($file, -1)
    ConsoleWrite($str & @CRLF)
WEnd

Any help?

while $str <> $Message
    sleep(200)
    $str = FileReadLine($file, -1)
    if @error<> 0 then ExitLoop; tests for EOF
WEnd
ConsoleWrite(@CRLF&"program exited loop")

Guys,

Why does he need to test for EOF? With the "line" parameter set to -1, the code is always reading the last line so there will never be an EOF return.

I did not know that, thanks M23.

thanks guys, im actually on the train right now so i will give it a shot when i get home. just a little context, what I am trying to do is run a query in a database with unix, and it will take between 5 seconds to 2 minutes, when the next command line is ready that means the query is done, then I will enter my next command

here are some of my custom functions, I have Putty output the results in a txt file on my desktop so I can interact with it

StartPutty($Puttypath, "db5")

ReadLog($PuttyLogpath, "[company@db5.prod ~]$ ")

sending("./generate_mtu_data.sh apps") //this is the query that will take 2 minutes to run

ReadLog($PuttyLogpath, "[company@db5.prod ~]$ ")

blah

blah

I presume the file will be written to at some point, otherwise the last line may never equal $Message, and you will still be stuck in an infinite loop. You may want to add a time out option anyway to prevent that from happening.
