C++ :: Error 453 - Can't Find DLL Entry Point

Using VC++ 2010 Express. I am creating a dll to export a simple Multiply function so I can use it in Excel/VBA

These e are the steps I am following :

. Create a Win32 C++ Project and give a name. For example: CallDllFromVBA
. Select the DLL option in the Wizard and click Finish
. In the CPP file (here CallDllFromVBA.cpp), add the following code

#include "stdafx.h"
int _stdcall Multiply(int x, int y) {
return x * y;

[Code] ....

The Build output show everything is ok as follows :

CallDllFromVBA.cpp
CallDllFromVBA.vcxproj -> c:documents and settingsadministrateurmes documentsvisual studio 2010ProjectsCallDllFromVBADebugCallDllFromVBA.dll
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========

In VBA, I insert a module and add the following code:

Declare Function Multiply Lib _
"c:documents and settingsadministrateurmes documentsvisual studio 2010ProjectsCallDllFromVBADebugCallDllFromVBA.dll" _
(ByVal x As Long, ByVal y As Long) As Long
Sub test()
MsgBox Multiply(2, 4)
End Sub

When I run the Test sub I get the error: 453 - Can't find dll entry point

I also opened the CallDllFromVBA dll with Dependency walker and I can't find the Multiply export function - In fact, the dependency walker doesn't show any function exports at all for the CallDllFromVBA dll !
