 Posted: Thu Jul 03, 2008 7:36 pm Post subject: Filter unwanted strings |
 |
|
I searched a lot, but it haven't worked out yet....
I want to filter out all the characters wich aren't alphabetic character or numbers.
| Code: |
string := Y#$*&a#^&@y*1
Do something
MsgBox %stringfiltered%
And it shows Yay1

exist sure an easier way but it works (used ASCII codes)
used in Embed TV example
http://www.autohotkey.com/forum/viewtopic.php?t=27264
| Code: | ;---------- remove special characters from string ----------------------
autotrim,off
AAA = Y#$* &a#-^&@y_*1
new2=
Loop,Parse,AAA
{
A:=(Asc(A_LoopField))
B:=chr(a)
if (B="_" OR B=" " OR B="-") ;allow some characters like _- and space when autotrim is off
Goto,SKIP8
if ((a<48 or a>57) AND A<65 OR A>90 AND A<97 OR A>122)
continue
SKIP8:
new2=%new2%%b%
}
msgbox,%new2%
return

Could be done in one line with RegEx*(), though I do not know how 
| Code: | MsgBox, % alnum( "Y#$*&a#^&@y*1" )
alnum( str ) {
loop, parse, str
If a_loopField is alnum
rstr .= a_loopfield
return rstr
} |

| Code: | InputBox, iString, String Check, Type in a string to be filtered.
FilterList := "@#$%^&*()"
fLen := StrLen(FilterList)
loop
{
StringMid, StopThis, FilterList, %A_Index%, 1
StringReplace, iString, iString, %StopThis% ,,All
if A_Index >= %fLen%
break
}
Msgbox %iString% |
That's what I came up with.
