I am pulling a version number from an embedded HTML window in an exe. Im trying to remove the last "." from the version number with StringTrimRight, but im having a problem.

#Include <IE.au3>
#Include <string.au3>
 
 
$oIE=_IEAttach("App Setup","Embedded",1)  ;attach to the application, the text is embedded HTML
$var=_IEBodyReadHTML($oIE)
$read=_StringBetween($var,"App ","<p>")
MsgBox(0,"",$read[0])
$trim=StringTrimRight($read,1)
MsgBox(0,"",$trim)

First Msgbox returns: 9.50.4.0. i want to trim the LAST "." from the number

Second Msgbox returns no text...what am i missing??

$read is an array, you can't use a string function on an array, you need an array function such as _ArrayTrim, or use StringTrimRight($read[0], 1) instead.

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.

use _ArrayToString() to turn it into a string then use that variable in the StringTrimRight()

Thought this was going to work...but i get the same results for both variables :graduated:

$oIE=_IEAttach("App Setup","Embedded",1)  ;attach to the application, the text is embedded HTML
$var=_IEBodyReadHTML($oIE)
$read=_StringBetween($var,"App ","<p>")
$read2=_ArrayToString($read)
MsgBox(0,"",$read[0])
$trim=StringTrimRight($read2,1)
MsgBox(0,"",$trim)

it may have been because you didnt have #include <Array.au3> at the top maby ;)

i did this and it worked

#include <Array.au3>
Dim $read[3] = ["10.", "20.", "30."]
$read2=_ArrayToString($read, "")
MsgBox(0,"",$read2)
$trim=StringTrimRight($read2,1)
MsgBox(0,"",$trim)

Edit: Problem Solved :graduated: it was part of the syntax i forgot about

Are you 100% sure that the last character in that string is "."? If there's a space after it, you're deleting the space. Try using StringStripWS($Read[0], 2) just before you use the StringTrimRight line.

chachew,

I would start by testing some return values after the function calls.

_arraydisplay() is also handy for quickly displaying an array

When i use StringTrimRight($read[0],1) i get the same result as MsgBox 1

If i use $trim=_ArrayTrim($read,1,1,0,0) then i get a result of "1"

If i use $trim=_ArrayTrim($read[0],1,1,0,0) then i get a result of "0"

What did you get in the array $read when you ran the first command? $trim is only going to be 1 or 0, the array is passed ByRef to the _ArrayTrim function. Try using a msgbox after the _ArrayTrim function to see what's in $read[0], something like this:

#include <Array.au3>
$read=_StringBetween($var,"App ","<p>")
MsgBox(0,"",$read[0])
_ArrayTrim($read, 1,1)
Msgbox(64, "", "|" & $read[0] & "|") ; I added the 2 "|" to make sure that the last and first characters are where you think they are

MsgBox(0,"",$read[0])
_ArrayTrim($read, 1,1)

With this suggestion i get the image below..

That tells me that there's something after the number that's not displaying in the msgbox,probably a CR or LF or 2. Try putting a StringStripWS($Read[0], 8) in there just before the first MsgBox, and see if it returns the same.

Arrrgggg...still happens

$read=_StringBetween($var,"App ","<p>")
StringStripWS($Read[0], 8)
MsgBox(0,"",$read[0])
_ArrayTrim($read, 1,1)
Msgbox(64, "", "|" & $read[0] & "|")

You need to start reading the help file a lot better, you have to assign the return of StringStripWS to a variable, try it using $read[0] = StringStripWS($Read[0], 8) ; you could substitute the 8 with 2 to just strip trailing WS instead of all of it.

chachew,

At some point we are going to need to see this HTML source!!!

Kylomas

The html is embedded in the exe so here is the actuall HTML itself:

<html>
<font face="Arial, Helvetica, Geneva">Welcome to the installer for App 9.50.4.0.
<p>
<b><font color='red'>Please disconnect any scanners and connect any printers or cameras to your system before continuing.</font></b>
<p>
<font size=-2">
It is strongly recommended that you exit all Windows programs before continuing with this installation.  
<p>
This installation will shut down any internet explorer windows that may be running before installation
<p>
If you have any other programs running, please click Cancel, close the programs, and run this setup again.
<p>
Otherwise, click Next to continue.</font></font>

Sweet, that works, now..i do see now where StringStripWS assigns to a variable :graduated: This is now the working code!

#Include <IE.au3>
#Include <string.au3>
#Include <array.au3>
 
 
$oIE=_IEAttach("App Setup","Embedded",1)  ;attach to the application, the text is embedded HTML
$var=_IEBodyReadHTML($oIE)
$read=_StringBetween($var,"App ","<p>")
$read[0]=StringStripWS($read[0], 8)
MsgBox(0,"",$read[0])
_ArrayTrim($read, 1,1)
Msgbox(0, "",$read[0])
