All in title,And I use ARX2002.The More details ,the better.~thanks!
I think the CUI API to create the screen menu programmatically was introduced in AutoCAD 2006. So the only way that I can think of is to manually create the screen menu using the CUI in AutoCAD and then have it displayed using the "acedMenuCmd" with "S" option.
The recent versions of AutoCAD do not have the screen menu, so unfortunately I do not have a sample to share with you.
