Creating a Reference to Another Project
 Close all open 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, please see the following articles in the Microsoft Knowledge Base:

156882 XL97 Err Msg: "Name Conflicts with Existing Module"

</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>
