When you open VB select AcitveX DLL project type ...
You may add some ot all of the objects (forms, classes, modules, etc) from your original and save as new copy each and every one of them.
This would give a start ...

The same way you can do in Standard project: right click on project explorer and select Add -> Add File ... But I recommend you to copy all files (frm, frx, cls, mod, ...) into a new folder and use that new folder as your work folder.

You must have at least one class which is multiuse and public so you can access your dll's methods, properties ...

excel_getdata
logion

You should learn a bit about ActiveX components so you understand how they work and especially how to design them. Then you need to design how your component needs to work. I doubt that it is possible to convert a exe project to a ActiveX component simply by copying the form.

VB programmers should avoid saying DLL since it can be confusing out of the context of VB. For VB, DLLs are never regular DLLs; for VB, a DLL is an ActiveX component or something like that. So it is more clear to say "ActiveX component" or something such as that, depending on what is relevant.

Also, I think it is possible to expose an ActiveX component from an exe project, but I don't know VB well enough to be sure. In other words, I think you can use your exe instead of converting to a DLL.
