CreeTar Posted January 14, 2010 Share Posted January 14, 2010 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 ^^ Link to comment Share on other sites More sharing options...
bogQ Posted January 14, 2010 Share Posted January 14, 2010 (edited) 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 :/ Edited January 14, 2010 by bogQ TCP server and client - Learning about TCP servers and clients connectionAu3 oIrrlicht - Irrlicht projectAu3impact - Another 3D DLL game engine for autoit.

jchd Posted January 14, 2010 Share Posted January 14, 2010 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.

CreeTar Posted January 14, 2010 Author Share Posted January 14, 2010 (edited) 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? Edited January 14, 2010 by CreeTar Link to comment Share on other sites More sharing options...
bogQ Posted January 14, 2010 Share Posted January 14, 2010 (edited) 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 Edited January 14, 2010 by bogQ TCP server and client - Learning about TCP servers and clients connectionAu3 oIrrlicht - Irrlicht projectAu3impact - Another 3D DLL game engine for autoit.

bogQ Posted January 14, 2010 Share Posted January 14, 2010 (edited) 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 Edited January 14, 2010 by bogQ TCP server and client - Learning about TCP servers and clients connectionAu3 oIrrlicht - Irrlicht projectAu3impact - Another 3D DLL game engine for autoit.

jchd Posted January 14, 2010 Share Posted January 14, 2010 (edited) 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. 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.
