I want to Make a Custom Toolbar Control

[lgcq]

Hi, Greetings from mexico (I apologize for my bad English)

Can anybody tell me if can i develop a "Custom Toolbar Control" to Display or Set Entity's Elevation,

and place it in the Properties toolbar.

I have the ability to program in AutoLISP language, Diesel and customization with MNL and DCL files.

So, do I need more knowledge?...Or is it simply impossible?.

I thank you in advance for the attention to my post.

With those languages, it doesn't seem possible.  With .NET maybe.  Changing an object's elevation is already possible with the properties palette though.

Do you mean creating one of these?

Nope. Not in your listed language.
