Madness Posted July 14, 2014 Share Posted July 14, 2014 (edited) Can someone show me an example of how the second parameter of this function is used if you specify a start point? I want to replace a character in a string, but only after a certain position. Not sure I can do this with StringReplace.

mikell Posted July 14, 2014 Share Posted July 14, 2014 Local $sString = StringReplace("123_a_456", 5, "b") MsgBox(0, "", $sString) ? Link to comment Share on other sites More sharing options...
Madness Posted July 14, 2014 Author Share Posted July 14, 2014 (edited) Got it. It looks like I will need to find the positions of what I want to replace, after a certain point, then loop back through with this.

water Posted July 14, 2014 Share Posted July 14, 2014 You can't combine Searchstring and start. Use something like this $iStart = 5 $sString = "aaabacadae" $sSearch = "a" $sReplace = "?" $sStringLeft = StringLeft($sString, $iStart - 1) $sStringRight = StringMid($sString, $iStart) ConsoleWrite($sStringLeft & StringReplace($sStringRight, $sSearch, $sReplace) & @LF) My UDFs and Tutorials: Spoiler UDFs:Active Directory (NEW 2022-02-19 - Version 1.6.1.0) - Download - General Help & Support - Example Scripts - WikiExcelChart (2017-07-21 - Version 0.4.0.1) - Download - General Help & Support - Example ScriptsOutlookEX (2021-11-16 - Version 1.7.0.0) - Download - General Help & Support - Example Scripts - WikiOutlookEX_GUI (2021-04-13 - Version 1.4.0.0) - DownloadOutlook Tools (2019-07-22 - Version 0.6.0.0) - Download - General Help & Support - WikiPowerPoint (2021-08-31 - Version 1.5.0.0) - Download - General Help & Support - Example Scripts - WikiTask Scheduler (NEW 2022-07-28 - Version 1.6.0.1) - Download - General Help & Support - Wiki Standard UDFs:Excel - Example Scripts - WikiWord - Wiki Tutorials:ADO - WikiWebDriver - Wiki Link to comment Share on other sites More sharing options...

kylomas Posted July 14, 2014 Share Posted July 14, 2014 (edited) Madness, You might do something like this... local $sTestString = 'ABCDEF_abcdef_ABCDEF_abcdef' Local $iStartpos = 27 local $sReplaceChar = 'X' local $sCharToReplace = 'f' for $1 = $iStartpos to stringlen($sTestString) if stringmid($sTestString,$1,1) = $sCharToReplace then $sTestString = stringreplace($sTestString,$1,$sReplaceChar) Next ConsoleWrite($sTestString & @CRLF) kylomas edit: Please disregard...solutions by water and mikell are much better Edited July 14, 2014 by kylomas Forum Rules Procedure for posting code "I like pigs.

mikell Posted July 14, 2014 Share Posted July 14, 2014 kylomas, local $sTestString = 'ABCDEF_abcdef_ABCDEF_abcdef_ABCDEF_abcdef' Local $iStartpos = 25 local $sReplaceChar = 'X' local $sCharToReplace = 'f' Msgbox(0,"", StringRegExpReplace($sTestString, '(?i)(?<=.{' & $iStartpos & '})(.*?)' & $sCharToReplace, "$1" & $sReplaceChar) ) Link to comment Share on other sites More sharing options...
kylomas Posted July 14, 2014 Share Posted July 14, 2014 (edited) mikell, Thank you for your help on this. @Madness - mikell came up with the above gem which I believe is the best solution to your issue! edit: if this dialog seems disjointed it is because mikell and I have been discussing this offline Edited July 14, 2014 by kylomas Forum Rules Procedure for posting code "I like pigs.

jchd Posted July 14, 2014 Share Posted July 14, 2014 Prompted to look at this I came up with another solution but it's ugly compared to what mikell offered: Local $sString = 'ABCDEF_abcdef_ABCDEF_abcdef_ABCDEF_abcdef_ff' Local $sRes = _ArrayToString(StringRegExp($sString, "(?|^(.{25}[^f]*)|f([^f]*))", 3), "X") ConsoleWrite($sRes & @LF) This wonderful site allows debugging and testing regular expressions (many flavors available).

mikell Posted July 14, 2014 Share Posted July 14, 2014 kylomas, A last detail : in case of $sCharToReplace is a special character, it's better to put the Q...E sequence StringRegExpReplace($sTestString, '(?i)(?<=.{' & $iStartpos & '})(.*?)\Q' & $sCharToReplace & '\E', "$1" & $sReplaceChar) Link to comment Share on other sites More sharing options...
