What is the proper way to pass string parameters between my host application, which is Access 2003, and my library, which is Visual Basic 6?

I am using the technique outlined in this article or here to create a standard DLL (not ActiveX/COM) using Visual Basic 6.  

My console output from the code below is:

If I hard code the string parameter as "\\server" inside the DLL it returns true.
'DLL Library
Public Function IsUNCPath(strPath As String) As Boolean
    On Error GoTo Error_Handle
    If Left(strPath, 2) = "\\" Then
        IsUNCPath = True
        IsUNCPath = False
    End If
    Exit Function
    Resume Exit_Procedure
End Function
'Calling Application
Private Declare Function IsUNC Lib "core" Alias _
    "IsUNCPath" (strPath As String) As Boolean
Sub TestCoreLibrary()
    Call LoadDLL("core.dll")   'load custom dll
    Debug.Print IsUNC("c:\") 'should return false
    Debug.Print IsUNC("\\server1") 'should return true
    Call UnloadDLL("core.dll") 'unload custom dll
End Sub
