Creating a Reference to Another Project
 Close all open Microsoft Excel workbooks, and then create two new workbooks. Save the workbooks as Book1.xls and Book2.xls in the C:\My Documents folder. Start the Visual Basic Editor (press ALT+F11). If the Project window is not visible, click Project Explorer on the View menu. In the Project window, click VBAProject (Book1.xls). On the Insert menu, click Module.

This step adds a module in the Book1.xls project.</li>  In the module, type the following code: Sub Create_Reference

Application.VBE.ActiveVBProject.References.AddFromFile _ "C:\My Documents\Book2.xls"

Use_Book2_Reference

End Sub

Sub Use_Book2_Reference

'Make calls to Book2.xls objects here.

End Sub NOTE: You cannot make reference calls to objects that have been added to the object library programmatically in the same procedure. You must run another procedure to make the calls. </li> In the Project window, click VBAProject (Book2.xls).</li> If the Properties window is not visible, click Properties Window on the View menu.</li> Next to the (Name) property, type Project2.

NOTE: If you want to create a reference to another project, that project cannot use the same value for the (Name) property.For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

213595 XL2000: Err Msg: Name Conflicts with Existing Module, Project, or Object Library

</li> Run the Create_Reference macro you created in step 7.

This step creates a reference in Book1.xls to the project in Book2.xls.</li> To verify the reference, click References on the Tools menu.

In the References - VBAProject dialog box, the Project2 check box should be selected.</li> Click OK.</li></ol>

Removing a Reference to Another Project
The following steps assume you followed all the steps in the "Creating a Reference to Another Project" section. <ol>  In the module in which you typed the Create_Reference macro, type the following code: Sub Remove_Reference

Dim x As Object Set x = Application.VBE.ActiveVBProject _ .References.Item("Project2")

Application.VBE.ActiveVBProject.References.Remove x End Sub </li> Run the Remove_Reference macro.

This step removes the reference to the project in Book2.xls.</li> To verify whether Microsoft Excel removed the reference, click References on the Tools menu.

In the References - VBAProject dialog box, the Project2 check box should be cleared.</li> Click OK.</li></ol>
