lets say that for an example I want a dll, with a sub that generates a beep, which I can call by the following line:

private declare sub beepme lib "mydll.dll"

and then, when clicking on a button:

private sub command1.click()
   beepme
end sub

how would I create such a DLL?????

I have VB5.0 Entreprise Edition

By the way, when i choose 'new project' it says 'active X DLL', not an 'average' DLL. Is That OK???

Active X DLL is not a regular DLL. Regular DLLs you cannot do with VB. You need C/C++, Assembler, Delphi... for that. But then there's PowerBasic/DLL. This is a commercial product, around $180 I think, of which you may find more information at http://www.powerbasic.com. From those who once wrote Borland's TurboBasic, now turned into the advanced PowerBasic for DOS. They have made several other products besides PowerBasic. One is PB/DLL, which comes in 2 fashions: version 2.0 (16 bits) and version 5.0 (32 bits). These may compile any VB program into small-sized true machine code that doesn't require any VB runtimes. They may also compile procedures into DLLs. Besides, they extend VB features by adding inline assembler, unions,... and a set of added functions (of which the ArraySort is most impressive). It's a well worth the money product for any VB professional programmer. Just check the site.

No, you can't do that. You have to do it this way:

Start VB
Select File, New Project, Select ActiveX DLL
Class1 will show. Paste this to Class1:

Option Explicit

Public Sub Beepme()
    Beep
End Sub

Now add new project - Standard EXE type.
Project2 will be added, default Form1 will show.
Set it As Startup Project (Right click in project explorer and select Set As Start Up)
In references (menu Project, References), add (check) "Project1"
Add command button to your form.
Paste this code to your form:
Option Explicit

Private Sub Command1_Click()
Dim oBeeper As New Project1.Class1
    oBeeper.Beepme
End Sub

It should beep!
