    <p>It looks like you don't really know what to do with the exception in <code>getUserInfo</code> and just want to pass it on to the outer function.</p> <p>Well, here's the great thing about exceptions: <em>They are passed on automatically!</em> There's nothing you need to do, and, in particular, you do not need to use the return value of the function for that. Just don't catch the exception <em>until you know what to do with it</em>.</p> <hr> <p>For example, in your case, just handle the error in the <em>calling</em> function instead:</p> <ul> <li><p>Remove the error handling code from the called function:</p> <pre><code>Public Function getUserInfo(ByValue testUserIdAs String) As DataSet Dim objTestWs As New TestWebService.UserMaintenanceSoapClient Return objTestWs.dsGetUserInfo(TestOU, PAC, paramUserID) End Function </code></pre></li> <li><p>and add it to the calling function, i.e., replace</p> <pre><code>... Dim dsUserInfo As DataSet dsUserInfo = getUserInfo() ... </code></pre> <p>with</p> <pre><code>... Dim dsUserInfo As DataSet Try dsUserInfo = getUserInfo() Catch ex As Exception ' Do whatever you want to do in case of an error here MsgBox("Could not get User Info: " &amp; ex.Message) Return End Try ... </code></pre></li> </ul> <hr> <p>One you are familiar with this technique, you can go on to more advanced topics like throwing your own exception, like @Justin suggested. Just make sure to include information about the <em>original cause of the error</em> in your own exception, for example, by copying parts of <code>ex.Message</code> into your own exception message and setting the <code>innerException</code> property.</p>

    1. COIt can be better to catch/throw a custom if he's potentially catching one of many exceptions in the calling function.

    2. CO@JustinEdwards: Yes, could be useful, but when done improperly this can lead to information about the original exception (and, thus, the original cause of the error) to be lost.

    3. COIn that case, it seems like throwing the message with the initial exception as the inner exception might be the way to go.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
