If it is COM exposed, you can do it as shown here otherwise you can import it into VBA .. perhaps build a COM interface and import it ... there are options, they may not necessarily be what you are looking for though.

Hi,

if your dll is .NET application using objectaRX 2007 or later, you can embed the function in a "LispFunction"

Look at the ObjectARX Developer's Guide > Using .NET for AutoCAD Development > ObjectARX Managed Wrapper Classes > Getting Started with Managed Wrappers > Defining Methods That Can Be Called From AutoLISP

What I mean is that the dll call WinAPI function, such as the timer in the user32.dll （function settimer）.
