<H5>Remarks</H5>
<BLOCKQUOTE>The <b>Source</b> property specifies a string expression that is usually the <A HREF="vbs0.htm#defClass">class</A> name or programmatic ID of the object that caused the error. Use <b>Source</b> to provide your users with information when your code is unable to handle an error generated in an accessed object. For example, if you access Microsoft Excel and it generates a <i>Division by zero</i> error, Microsoft Excel sets <b>Err.Number</b> to its error code for that error and sets <b>Source</b> to Excel.Application. Note that if the error is generated in another object called by Microsoft Excel, Excel intercepts the error and sets <b>Err.Number</b> to its own code for <I>Division by zero</I>. However, it leaves the other <b>Err </b>object (including <b>Source</b>) as set by the object that generated the error. <P>
<b>Source </b>always contains the name of the object that originally generated the error — your code can try to handle the error according to the error documentation of the object you accessed. If your error handler fails, you can use the <b>Err</b> object information to describe the error to your user, using <b>Source </b>and the other <b>Err</b> to inform the user which object originally caused the error, its description of the error, and so forth.<P>When generating an error from code, <b>Source</b> is your application's programmatic ID. <!--For <A HREF="vbs0.htm#defClassModule">class modules</A>, <b>Source</b> should contain a name having the form <i>project</i><i><b>.</b></i><i>class</i>.--></BLOCKQUOTE>
