Difference between AutoLISP and VisualLISP

Dear readers,

Today I will try to talk about the differences between AutoLISP and VisualLISP. VisualLIPS has made the software a lot easier ever since the R14 edition of AutoCAD. As I gather, VisualLISP is not commonly used here in our country, Turkey. At least, my Google search has proven so.

For you to be able to see the difference more clearly, I present you two kinds of programs. One of them is the C:F1 command and the other is the C:F2 command (Code.3). They both do the same thing: Give your selection the red color property.

The sub-program the C:F1 function uses is clearly the more capable one “Change-Color-F1” (Code.1). when you edit an object with AutoLISP, you need to have its DXF information.

The Visual Lisp/ ActiveX programming requires more experience but it is easier to use its methods once you edit an object. That is, for example, you use the vla-put-color method if you want to edit the color of an object. You don’t need to know a lot of English either, the names of the methods are quite self-explanatory.

We use the ActiveX name provided by Microsoft for its VBA software in VisualLISP language because its foundation is built on VBA.

Code.1 – The “Change-Color-F1” function that operates with the DXF code.

Code.2 – The Active-X Function “Change-Color-F2“

Code.3 - Main Functions; “C:F1” and “C:F2“

Have a nice time,
