Q129636: PRB: "Ambiguous name detected" Compile-Time Error in VB 4.0

Article: Q129636
Product(s): Microsoft Visual Basic for Windows
Version(s): 4.0
Operating System(s):

The information in this article applies to:

- Microsoft Visual Basic Professional Edition, 16-bit, for Windows, version 4.0 
- Microsoft Visual Basic Professional Edition, 32-bit, for Windows, version 4.0 
- Microsoft Visual Basic Enterprise Edition, 16-bit, for Windows, version 4.0 
- Microsoft Visual Basic Enterprise Edition, 32-bit, for Windows, version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Better type checking in Microsoft Visual Basic version 4.0 causes it to return a
compile-time error message when you declare two functions (or subroutines) with
the same name in the same module or form. This is a change in behavior from
Microsoft Visual Basic version 3.0.

The error message returned is:

  Ambiguous name detected: <function or sub name>

STATUS
======

This behavior is by design.

Steps to Reproduce Behavior
---------------------------

1. Start a new project in Visual Basic. Form1 is created by default.

2. Add the following code to the general declarations section of Form1:

     Private Declare Function GetSystemDirectory Lib "Kernel" _
        (ByVal strBuffer As String, ByVal intSize As Integer) As Integer
     Private Declare Function GetSystemDirectory% Lib "Kernel" _
        (ByVal lpBuffer$, ByVal nSize%)

3. Attempt to run the application by pressing the F5 key. Visual Basic will not
  run the application. Instead you will get this error message:

  Ambiguous name detected: GetSystemDirectory
