If your DLL is an ActiveX DLL you do not need to declare it, you just set a reference to it.<br />

You cannot easily <br />
You have to connect to it using a COM mechanism for example ATL...<br />
<br />
Choose project/add to project/ component and controls and select the TstClass as mentioned in my example<br />

If, as you state in your original question, you use your dll in VB by declaring the function(s), then it is not an ActiveX dll.<br />

Question abou Visual Basic DLL

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.

Microsoft Development

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
