Selecting specific text

[Dorian Gray]

Does anyone know how I can select specific text, such as text that beings with bw and change to a layer.....

I was having a look at the object selection filter and qselect but can't seem to get anywhere.

SSX doesn't have anything either....

Cheers

this worked the few times I tried it, not a whole lot of error control...

(defun c:test (/ pre prelen ln  ss idx cnt obj)
 (vl-load-com)
 (setq pre (getstring "\nEnter prefix (case sensitive):")
   prelen (strlen pre)
   ln (getstring "\nEnter Layer name: ")
   )
 (if (not (tblsearch "layer" ln))
   (princ "\nLayer does not exist")
   (progn
   (setq ss (ssget "X" '((0 . "*TEXT")))
     idx 0
     cnt 0)
 (repeat (sslength ss)
   (setq obj (vlax-ename->vla-object (ssname ss idx))
     )
   (if
     (= pre (substr (vlax-get obj 'Textstring) 1 prelen))
     (progn
     (vlax-put obj 'Layer ln)
     (setq cnt (1+ cnt))
     )
     )
   (setq idx (1+ idx))
   )
   (princ (strcat "\n" (itoa cnt) " text entities moved to layer " ln))
   )
 )
 (princ)
 )

 

======================

Why use lisp when Acad has the ability built in...

use Geobuilder's suggestion below

[BearDyugin]

quick select -> Properties [Contents] -> The operator [* search with global symbols] -> Value [bw*] -> Ok )Translation can be not exact, look on sense)

How does that lsp routine work am i required to alter anything....I tried entering but it didn't work, can you explain a little better???

And the quick select doesn't work either, I'm using 2010 - this is what I selected

Apply to: entire drawing

Object type: Mtext

Properties: Contents

Operator: *

Value: BW*

Command line:

Command: _.QSELECT

0 item(s) selected.

Q1. Look here http://www.cadtutor.net/faq/questions/28/How+do+I+use+an+AutoLISP+routine%3F

 

Qselect works... it's case sensitive

if the text in the drawing starts with bw and you enter BW* as the Value, nothing will be selected.

 

or... maybe it's not Mtext, try Text as the Object type
