It contains a group of Error objects that you can examine in order to understand the error. However, this is not the same as detecting an error -- although closely related. The "count"-property of the Errors collection returns the number of Error objects present, thus you use it best to detect errors. <p> <% # Create an instance of a Connection object # $conn = $Server->CreateObject("ADODB.Connection"); # Open it by providing a System DSN as the parameter # $conn->Open( "ADOSamples" ); # Deliberately cause an error by typo'ing the query # $conn->Execute( "ZELKECT * FROM Orders" ); if($conn->Errors->{Count} > 0) { $Response->Write("There's been an error ..."); $Response->Write($conn->Errors(0)); } $conn->Close(); # Close the connection undef($conn); # Destroy the object %> <!-- +++++++++++++++++++++++++++++++++++++ here is the standard showsource link - Note that PerlScript must be the default language --> <hr> <% $url = $Request->ServerVariables('PATH_INFO')->item; $_ = $Request->ServerVariables('PATH_TRANSLATED')->item; s/[\/\\](\w*\.asp\Z)//m; $params = 'filename='."$1".'&URL='."$url"; $params =~ s#([^a-zA-Z0-9&_.:%/-\\]{1})#uc '%' . unpack('H2', $1)#eg; %> <A HREF="index.htm"> Return </A> <A HREF="showsource.asp?<%=$params%>"> <h4><i>view the source</i></h4></A> </BODY> </HTML>
