    <p>I have cross posted on <a href="http://access-programmers.co.uk/forums/showthread.php?t=144006" rel="nofollow noreferrer">access-programmers.co.uk</a></p> <p>Please post responses on that forum is possible..</p> <p>I have compiled a dll in c# 3.5.. where I set the solution properties to register the build for COM interop.</p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Runtime.InteropServices; namespace SBG_TestWithVBA { [ClassInterface(ClassInterfaceType.AutoDual)] public class TestHello { [ComVisible(true)] public string SayHello(string name) { string message = "Hello " + name; return message; } public string HelloWorld() { string message = "Hello World!"; return message; } } } </code></pre> <p>I have then registered the assembly and tlb file using</p> <blockquote> <p>"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regasm.exe" "\sbgfs01\users\Vincent Pirolli\My Docs\Visual Studio 2008\Projects\TestWithVBA\TestWithVBA\bin\Release\SBG_TestWithVBA.dll" /tlb: "\sbgfs01\users\Vincent Pirolli\My Docs\Visual Studio 2008\Projects\TestWithVBA\TestWithVBA\bin\Release\SBG_TestWithVBA.tlb"</p> </blockquote> <p>I then add the tlb file within vba from the tools>references menu..</p> <p>and my VBA code is as follows:</p> <pre><code>Sub test() Dim f As SBG_TestWithVBA Set f = New SBG_TestWithVBA f.HelloWorld End Sub </code></pre> <p>I get the following error even though Intellisense works within the VBA editor: <strong>"Automation error The system cannot find the file specified."</strong></p> <p>Anyone got any ideas? I have the articles in the previous posts but I cannot find the solution.</p> <hr> <p>ok, this is really annoying me now..</p> <p>i've managed to get this to work.. but i dont understand why..</p> <p>In solution properties within visual studio.. on the Build tab i set 'Register for COM interop' to true, and within 'Application>Assembly Information', i set 'Make assembly COM-Visible' = TRUE..</p> <p>I have the VS project files in a shared drive. Now if i set the build location to the bin folder on the share drive, under my project files, when i call from VBA it doesnt work.. However, if i set the build folder to a folder on my local C Drive, then it works fine when calling from VBA..</p> <p>Any ideas?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
