How an I create a NORMAL (not ActiveX) DLL with VB5.0 EE?

I want: (IF POSSIBLE)

Declare MyFun lib "xxx.dll" (x as xxx) as xxx
in the declaration part of my module

and
xxx = MyFun(x)

to be the only lines of code I need to write to get the function working.

It is not possible to create a "classic" DLL under VB5.

You could create an OLE 2 Server exporting classes, and within those classes, showing your functions.

I will find a sample and post it for you.

NB : I have a sample, you can find it on my web site :
  http://www.geocities.com/ResearchTriangle/6311/ 

Download the Gradient TitleBar. It is a complete VB Source code implementing gradient in the titlebar.

It is in fact an Active DLL exporting a class (class_TitleBar).
In the sample, we add a reference to this Active DLL, and in code, we create a variable of this class :
   Private m_cT As New class_TitleBar

After that, you can call functions inside :
   m_cT.Picture = picLogo
   m_cT.GradientForm Me
   m_cT.RefreshTitleBar

You can call this DLL from every langage supporting OLE2 (Delphi, Office, Powerbuilder...). One restriction is that you need to install the Runtime DLL of VB5

It is not possible with VB (waty's example is an activex dll).
However, there is an application that will allow you to write true dlls using a BASIC syntax.  Check out PB/DLL from power basic (www.powerbasic.com)

EWWW Stay away, FAR AWAY, from Powerbasic.  It's unstable, and produces DLLs that are unstable.

I would except the GFA Basic no longer exists (in the US, at any rate).
