我的意思是如何使用on error resume next？如何捕获错误？程序代码运行的顺序是什么？

[hope2002]

<% on error resume next %>
加入上面的那条语句，意思是将一切系统的错误提示屏蔽，这时如果想要处理错误信息的显示只能是利用Error对象！
if err.number >0 then
response.write "发生错误<br>"
response.write "数据代码:"&Err.Number&"<br>"
response.write "代码说明:"&Err.Description
else
response.write "<center>成功，请返回!</center>"
end if

gObjDC.Open pDSNName, "", ""
If Err <> 0 Then
Response.Clear
Response.Write "<H1> JTMR aspMyAdmin Error </H1>"
Response.Write "<P>The DSN <I>" & pDSNName & "</I> is invalid...</P>"
Response.Write "Return to <A HREF='../welcome.html'>JTMR aspMyAdmin :: Home Page</A>"
Response.End

Sub CloseConnection
gObjDC.Close
