Topic: TIP: converting to a string

[Columbia]

Here's something I just ran across.  It's been around a while, but there are often tricks that are sometimes overlooked.

If you want to convert something (real or integer) to string and format is not a real big concern try using (vl-prin1-string) as in:
(setq x 1 y 1.5)
(vl-prin1-string x) returns "1"
(vl-prin1-string y) returns "1.5"

This could come in handy when dealing with dialog boxes.  I hope you all enjoy.

You should like this

_$ (vl-prin1-string x)
; error: no function definition: VL-PRIN1-STRING

_$ (vl-prin1-to-string x)
"1"
_$

You might want to make sure that COM interface for Visual LISP is loaded by issuing (vl-load-com).

If that doesn't work, call the ghostbusters.

It'd also be nice to know what version of autocad Adesu is using??

The problem is not loading the COM interface or the Acad version.

VL-PRIN1-STRING does not exist as a built in function.

VL-PRIN1-TO-STRING does

Yeah, well, so I can't type worth a hoot.  So what.  You don't have to make fun of me.... :crazy:
