Read a variable and extract 3 caracters

[Kyan]

Hi,

Can someone tell me whats the combination of commands to read a variable (downloaded from internet), search for a specific string like "FileSize=" and extract the next 3 caracters in front this string?

I already write this:

$dtxt = BinaryToString ($readtxt)
   $txtsplit = StringSplit($dtxt,"FileSize=",1)
   $ver = StringTrimLeft($txtsplit[1],3)

but gives-me nothing or 25 :s

Thanks for your time

EDIT: the start is "FileSize=" the end of this parameter is a semicolon

I'm digging arround but I cannot get the first 2 digits, and the next 2 forward the dot: StringRegExp($txtsplit[2], '([0-9]{1,2})[.]([0-9]{1,2})', 1)

example: FileSize=34.94MB

please help me out

What are you trying to do with the BinaryToString Function? if you are trying to read a variable to string, theres no need for that because you could read the string strait away without the need of converting.

What do you mean; do you want to download a file from the internet?

Do you want it like this:

$Size = StringRegExp("FileSize=34.94MB", '(?i)FileSize=(.*?)(.)MB', 1)
MsgBox(0,"",$Size[0])

I'm trying to get the size of a file listed in a txt (previously downloaded from internet...) in this example is "34.94" MB

thanks btw

Here's a way using the _StringBetween() UDF.

#include <String.au3>
$string = "FileSize=34.94MB"
$array = _StringBetween($string, "FileSize=", "")
ConsoleWrite($array[0] & @LF)

awesome! thanks a lot

You bet. Good luck with the rest of your project. You should remember though, that $array[0] will contain everything after FileSize=.

and it don't work only with $array?

can I for example get 5 caracters before the searched string?

charsIwant--FileSize=...

[somdcomputerguy]

Do you get this? Ask if you need clarification.

#include <String.au3>

$var1   = "FileName=foo.txt FileSize=34.94MB more text"
$var2   = " FileSize="

$array1 = _StringBetween($var1, $var2, "")
$array2 = StringSplit($var1, $var2, 1)

ConsoleWrite($array1[0] & @LF & StringRight($array2[1], 7) & @LF)

You can't use an Array as $array, it has to have a number at the end with brackets depending on the the number of things that are declared in the Array.

For example if my Array was something like below then if i wanted a value from a specific location such from row 1 column 1, it would be: $array[0][0]

$array[2][4] < this means that my array has 2 rows and 4 columns.

$array[2] < this means that my array has 2 rows and to get the value from this you use: $array[0] which will return the row 1 data.

This will return the two things you want:

$Size = StringRegExp("FileName=Dotx.txt FileSize=34.94MB", '(?i)(?s)FileName=(.*?).FileSize=(.*?).MB', 1)
MsgBox(0,"",$Size[0]); First value
MsgBox(0,"",$Size[1]); Seconde value

1) This is not really the correct forum for this question.

2) DiOgO, I realize you are new at this, or maybe programming/scripting altogether, but these are the kind of threads and questions I hate. You are asking basic language questions, implying you haven't even opened the help file or done any reading on basic concepts such as strings, substrings, or arrays. You need to stop now, cease creating new threads, and do some work on your own. Once you have the basics down you can start to build things. THEN start in on regular expressions. They are confusing and an advanced concept... work up to it.

Once you've laid the ground work for what you want to do, you can come back and ask intelligent questions which may garner help from the more experienced people on this board. Most won't even take the time to write what I have so far until you've done at least that much.

yap, thanks

sorry for that incovenint, I lost 3hours to get that string, I started a 2-3days ago scripting I already have done a program that checks a online file, gets a url from that txt plus other text, display it in the GUI, download the file with progress bar...etc...etc, and does the md5 hash check.

not bad for the first script, but there's somethings I don't know, I really spend many hours in the help file, but when I notice that I can't do it is when I asked. An example of this is the StringRegExp, I don't get it how combine all the parameters etc..

Once again sorry for the dumb questions and for the grammar inssues, my native language is not the english.

I'm not talking about inconvenience or language differences, but basic usage of things like arrays. That is all covered in the help file. FWIW, pretty lofty goal for a first script... so do it right!

For regex's, you should *start* here: http://www.autoitscript.com/autoit3/pcrepattern.html

That link is in the help file page you specified, BTW. Start there, but it is certainly not exhaustive on regex's. Google will find you more info that you could possibly need.

thank you

its more easier with the command and the output related

could you give a look at this topic: ?

just how to get the output percentage to a variable

and this is the way to check a combobox? seems much lines to verify all the checkbox...

Case $CompMenuItem0
   $readmenu = ""
   $readmenu = GUICtrlRead($CompMenuItem0)
   if $readmenu = 68 Then
      GUICtrlSetState($CompMenuItem0, $GUI_CHECKED)
      GUICtrlSetState($CompMenuItem1, $GUI_UNCHECKED)
      GUICtrlSetState($CompMenuItem2, $GUI_UNCHECKED)
      GUICtrlSetState($CompMenuItem3, $GUI_UNCHECKED)
      GUICtrlSetState($CompMenuItem4, $GUI_UNCHECKED)
      GUICtrlSetState($CompMenuItem5, $GUI_UNCHECKED)
   EndIf
