StringInStr is not finding string containing a number

10 posts in this topic

Hello there, since I am so confused, I wanna ask here if it's a fault on my side...

I check if a string contains "Internet Explorer 8", the string is from an UpdateCollection (IUpdate via ISearchResult via IUpdateSession...)

$test1 = StringInStr($IUpdate.Title, "Internet") ;returns 1
$test2 = StringInStr($IUpdate.Title, "Internet Explorer") ;returns 1
$test3 = StringInStr($IUpdate.Title, "Internet Explorer 8") ;returns 0!!! oO

If I fill $IUpdate.Title manually it works, if I use it filled by WindowsUpdateAgent it doesn't.

Then I made a test messagebox:

msgbox(0,"IE8","#" & $IUpdate.Title & "#" & @CRLF & "#Internet Explorer 8 für Windows XP#")

And it looks like this:

#Internet Explorer 8 für Windows XP#

#Internet Explorer 8 für Windows XP#

so filled manually or from WUA seem to have the same string.

I also tried

$ttest = String($IUpdate.Title)
$test1 = StringInStr($ttest, "Internet Explorer 8") ;returns still 0

I am sitting here now since like 20min. or so trying everything, reading help over and over...

Please help ^^

So what does @Error return?

Remarks

The first character position is 1.

So if its geaving 0 there is probably something wrong (string dont contain a given substring)

Edit:

You can try to compare every char to see if its identical

something like this

#include <Array.au3>
$c = StringSplit("Internet Explorer 7","")
$a = StringSplit("Internet Explorer 8","")
Dim $b[$c[0]+1][2]
For $y = 1 To $c[0]
    $c[$y] = Asc($c[$y])
    $b[$y][1] = $c[$y]
    $a[$y] = Asc($a[$y])
    $b[$y][0] = $a[$y]
Next
For $r = 0 to UBound($b,1) - 1
    If $b[$r][0] <> $b[$r][1] Then MsgBox(0,$b[$r][0]&" diffrent from "&$b[$r][1]&" pos. "&$r,"'"&Chr($b[$r][0])&"' diffrent from "&"'"&Chr($b[$r][1])&"' on position "&$r)
Next

If it dont work than maby someone other can assist and help you better than i did :/

Look at the hex version of your target string. It's possible that a non-conventional whitespace or non-normalized Unicode string is the cause of this. Only hex examination can tell.

hehe, i used your script and it says:

31 different from 160 pos. 18

'' different from '' on position 18

So does it mean its ASCII 31 vs. ASCII 160? But 31 is underscore and i don't see the underscore,

i got a log file and it says:

2010-01-14 20:37:00 >> Checking available updates
2010-01-14 20:37:05 >> 1 updates found: Internet Explorer 8 für Windows XP
2010-01-14 20:37:07 >> Downloading 1 of 1 Internet Explorer 8 für Windows XP
2010-01-14 20:37:10 >> Installing 1 of 1 Internet Explorer 8 für Windows XP IE-Tags 1/2: 0/0
2010-01-14 20:37:24 >> Result for 1 of 1 Internet Explorer 8 für Windows XP: failed (Exception: 80240022)

So how can I avoid this, if I don't even "see" the difference? Is there a way to convert the string?

probably the one way around it is to stringreplace($string,Chr(160),Chr(31)) "or replace($string,Chr(31),Chr(160))" and then test stringinstr

Aww, I wanted to avoid such "hardcoded" solution, then i might try to remove simply all whitespaces including 31 and 160.

that way i should be safe without getting down to chars again.

Well you can try it

In help file you have

ASCII Character (Codes)

under Appendix Reference and to replace anything that look like wihte space with "" nothing

There are probably better solutions like StringRegExp but i still did not learn how to use (one day i will that's for sure) it and i dono can it help you heare

ASCII decimal 31 (0x1F) is US (Unit Separator) aka ^_ (Ctrl underscore, not underscore itself), while decimal 160 (0xA0) is a non-breakable whitespace.

Sounds like there is little consistency in ID strings returned by IE!

Those two non-conventional pseudo-whitespaces aren't even considered as whitespace by the classical tokens of regexp, including Posix.

You'd better then compare filtered versions after a regexp keeps only letters and digits. Not completely failproof, but who knows with special/control caracter IE string will contain in the next version/release/patch?

EDIT: sorry, I didn't notice you were rather new here!

So Welcome and here's what you can use:

$FilteredStr = StringRegExpReplace($Str, '[^a-zA-Z0-9]' '')

Litterally: replace any character of input string not an ASCII letter nor an ASCII digit by nothing.

Output will look a bit compact, but you just compare it, you don't read it after all.

Thanks for the example, I always struggle a bit with RegEx :D

You lucky man. Regexp are cool friends compared with the dragon personified by my mate...

Any taker around?
