could someone try replacing "\\" with "\\\\" using vl-string-translate or vl-string-subst? (vl-string-subst "\\" "\\\\" "g:\\test1\\test2\\") returns = "g:\\test1\\test2\\" (vl-string-translate "\\" "\\\\" "g:\\test1\\test2\\") returns = "g:\\test1\\test2\\" (dos_strreplace "g:\\test1\\test2\\" "\\" "\\\\") returns = "g:\\\\test1\\\\test2\\\\" <<<---this is what i'm looking for thanks, daron
Daron, the vl-string-subst substitute only the first one the function finds. something like this: (defun string-to-list (str pat / i j n lst) (cond ((/= (type str) (type pat) 'STR)) ((= str pat) '("")) (T (setq i 0 n (strlen pat)) (while (setq j (vl-string-search pat str i)) (setq lst (cons (substr str (1+ i) (- j i)) lst) i (+ j n))) (mapcar '(lambda (x) (vl-string-trim " " x)) (reverse (cons (substr str (1+ i)) lst)))))) (apply 'strcat (mapcar '(lambda (str) (strcat str "\\\\")) (vl-remove-if-not '(lambda (str) (/= str "")) (string-to-list "g:\\test1\\test2\\" "\\")))) "g:\\\\test1\\\\test2\\\\" hth. -- Get your free DRAFTTEAM version 1.4 cop(ies)!, How? download it from here: http://www.draftteam.com/draftteam/draftteam.zip Or sent your request to: [A comprehensive set of drafting routines to enhance and supplement the use of AutoCAD.] Offer ends on Friday, January 23 of 2004
thanks Luis. i wish you hadn't gone to all the trouble, i was just looking for confirmation. ) but again, thank you. daron
Daron, Confirmed(but you were doing it backwards) and it will only find the first instance from left. It couldn't find an instance of "\\\\" (vl-string-subst "\\\\" "\\" "g:\\test1\\test2\\")

This might not be the most efficient, but it's relatively bomb proof ( or that's the illusion I'm enjoying ) - it won't be tripped up into endless loops by identical or similar old and new strings ( improvements anyone might have to offer are welcomed ). Of course, you'd never want to send it a old, new or original string of "-=+#|\001*\377*\001|#+=-", though I consider the odds of that coming up *PRETTY* low. Code: (defun Replace ( OldStr NewStr Str / &Replace TempStr ) ; local defun (defun &Replace ( OldStr NewStr Str / i ) (while (setq i (vl-string-search OldStr Str)) (setq Str (vl-string-subst NewStr OldStr Str i) ) ) Str ) ; "main" (cond ( (or (eq OldStr NewStr) (eq "" OldStr)) Str) ( (eq NewStr "") (&Replace OldStr NewStr Str)) ( (vl-string-search OldStr NewStr) (&Replace (setq TempStr "-=+#|\001*\377*\001|#+=-") NewStr (&Replace OldStr TempStr Str) ) ) ( (&Replace OldStr NewStr Str) ) ) ) (Replace "\\" "\\\\" "g:\\test1\\test2\\") Returns "g:\\\\test1\\\\test2\\\\" Cheers, Michael. ~ ~ ~ "Daron Denton" <ask, and i'll give it to you> wrote in message could someone try replacing "\\" with "\\\\" using vl-string-translate or vl-string-subst?
