cant find dll entry point for a function

[thewhip]

the dll was created in VB.  The public function name is very simple(one letter "A&quot.  It is just a test for bigger and better things.  It takes one string parameter and returns a string.  It displays a msgbox with that parameter.  I make the Dll(there is only one anywhere on the system).in a new standard project I declare the function and correct Lib and parameters in and out.  When I call it the project finds the dll OK, but it can't find the functions.  What am I missing?1. I am calling it by name with proper case (its only A)2. I can't be the version because it does it even the first time i make the dll?3. I am not using an alias.4.  If I have methods etc in the class, I can instantiate it and use them, but I am testing for another language where I will not have access to the methods, I need to access a function directly.

Assuming that you have made the dll available to the project,<br>under project -&gt; references, you can test whether or not vb<br>is finding the code by typing in projectname (or dll name) <br>period.&nbsp;&nbsp;If vb doesn't then list what (method(s)) is/are available<br>in the dll, it's not going to work. <p>Jim<br><a href=mailto:nx56@inetarena.com>nx56@inetarena.com</a><br><a href= > </a><br>oracle, vb, some javascript

That is the problem. I CAN access methods properties etc if I create a reference.&nbsp;&nbsp;I have to access a function because of the limits of the environment that I will eventually will be using it in.&nbsp;&nbsp;So in the end I will be wrapping the methods and properties up into functions with parameters.&nbsp;&nbsp;As a test I tried to create this simple function in a module, but I can't access it.

The Whip -<br><br>Two things you said make me think you're trying to access a VB dll as if it were a C/C++ dll.&nbsp;&nbsp;You said &quot;the dll was created in VB.&quot; and then &quot;in a new standard project I declare the function and correct Lib and parameters in and out.&quot;<br><br>VB only can create Active-X dlls.&nbsp;&nbsp;To use them you would use either a reference to them (early binding) or do a CreateObject on them (late binding).&nbsp;&nbsp;You wouldn't use a Define statement on them.&nbsp;&nbsp;The Define is used with system APIs and dll's created by a C development tool.<br><br>Chip H.<br>
