Using Eval to set dynamic object names

[webteam]

I've ran into a little trouble with Eval, hoping someone can point it
out to me

This code works :

var_ktml = "textarea2"
Set ktml_textarea2 = new ktml4
Eval("ktml_" & var_ktml).Init var_ktml

This code doesn't :

var_ktml = "textarea2"
Set Eval("ktml_" & var_ktml) = new ktml4
Eval("ktml_" & var_ktml).Init var_ktml
Can anyone point out the error of my ways ?

Cheers,
Mark

Simple, stop using Eval.

Use an array or even Scripting.Dictionary to collect and lookup objects

Sure. You see that line that starts with "Eval ... "? That's the problem
right there*.
Try this instead:

dim var_ktml,ktml_objs, ktml_obj
set ktml_objs = createobject("scripting.dictionary")
var_ktml = "textarea2"
Set ktml_obj = new ktml4
ktml_objs.Item("ktml_" & var_ktml) = ktml_obj
When you want to use the object:

Set ktml_obj = ktml_objs.Item("ktml_" & var_ktml)
ktml_obj.Init var_ktml
ktml_objs.Item("ktml_" & var_ktml) = ktml_obj
