Using the functions

For example

I have created many functions and procedures in the AddIn (MyAddin.dll) for
using in other VB6 applications.
One of this function called

Cosh(Alfa as Double) as double (defined as public)

Normaly will be declared Functions from .dll modules in the form

Private Declare Function GetProfileString Lib "kernel32" Alias _
"GetProfileStringA" (ByVal lpAppName As String, _
ByVal lpKeyName As String, ByVal lpDefault As String, _
ByVal lpReturnedString As String, _
ByVal nSize As Long) As Long

What should be the syntax for the function call Cosh(Alfa) in the module
MyAddin.dll (see function definition above)?

You don't create Declares for ActiveX components. You create references to
them and, at runtime, create instances of their public classes... but, as I
mentioned when you asked this before, your "Add In" is not designed to work
like you might think it is. If you use its functions, you *will need to
package it with any app that uses it*

I think your terminology is confusing people; an addin is something you load
into the VB IDE to help when coding. It is a DLL but it's a special-purpose
one with specific functionality so that VB knows how to call it.

A set of classes can be compiled into a DLL for use by any application that
knows how to call them but that's not generally called an addin, especially
in the VB world.

There are two kinds of DLLs; the API call you showed as an example is a
"standard" DLL and that's how windows exposes it's functions. VB can not
create that kind of DLL (at least not without help). When you create a DLL
in VB you create an ActiveX DLL which is used from other projects by adding
a reference to it and creating an instance using new as in:
Dim x As MyAddin.MyClassname
set x=new MyAddin.MyClassname
Call x.Cosh(whatever)
orby using CreateObject
Dim x As Object
Set x=CreateObject("MyAddin.MyClassname")
