Hello !

I like to make a dll for the my first time so I have put this function in a classmodule in a ActiveXdll project to test if it works:

 Public Function Convdbl2(var As Variant) As Double
'Convert Null to 0.
    If IsNumeric(var) Then
        Convdbl2 = CDbl(var)
    Else
        Convdbl2 = 0
    End If
End Function

And in my standard exe i have declare the function:

Declare Function Convdbl2 Lib "AUStyr32.dll" (ByVal var As Variant) As Double

But when i try to use it in my standard exe like: d# = Convdbl2(Null)
I get the error message:

Can´t find DLL entery point Convdbl2 in AUStyr32.dll.

Why, and how so solve it ?

1. Remove the Declare Statement in the standard exe.

2. Select Project -> Reference menu item in VB IDE.

3. Find the entry for your ActiveX DLL in Available References and check that ON and click on OK.

3a. In the above step you can make out your DLL name in the bottom Location Field in OLE Automation frame. If you don't find it use Browse button and add it.

4.Save the project.

5. Now run the App and see.
