Error 13 error C2871: 'CheckIn' : a namespace with this name does not exist

[sushilkaushik]

In my VC++ project (using Visual Studio 2005) I have two DLLs : CommonClasses.dll and CheckIn.dll

I added both of them in exactly the same way. First, CommonClesses and then CheckIn, using Project->References

Added the header files from both the DLLs into my project. Set the Include_Dir and Reference_Dir to the header file and DLL location respectively.

I have this in one of my project file:

#include "Helpers.h" // from CommonClasses.dll
#include "FrmCheckIn.h" // from CheckIn.dll


using namespace System;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Windows::Forms;
using namespace System::Data;
using namespace System::Drawing;
using namespace CommonClasses;
using namespace CheckIn;

Now when I build the project, I get the following error:

Error 13 error C2871: 'CheckIn' : a namespace with this name does not exist

Any suggestion?

ThanX.
