关于错误信息的显示 (转)

关于错误信息的显示 (转)[@more@] ASP 程序出错后，错误提示不是很清楚明白，让人摸不着头脑，用下面方法看看有没有帮助（此法目前只适合处ADO错误外的错误）
步骤一，用编辑器打开c:winnthelpiisHelpcommon500-100.asp
将它另存为500-101.asp 备份(以便日后恢复）
步骤二，将下面的代码覆盖500-100.asp原 文件，保存退出
步骤三，创建新文件test.asp，添加如下代码
，存盘退出
步骤四，在 浏览器中输入localhost/test.asp查看结果

500-100.asp的新代码：
vbscript" %>
Option Explicit

Const lngMaxFormBytes = 200

Dim objASPError, blnErrorWritten, strServername, strServerIP, strRemoteIP
Dim strMethod, lngPos, datNow, strQueryString, strURL

If Response.Buffer Then
Response.Clear
Response.Status = "500 Internal Server Error"
Response.ContentType = "text/html"
Response.Expires = 0
End If

Set objASPError = Server.GetLastError
%>
A href="tag-88-1.html">w3c//DTD HTML 3.2 Final//EN">

本页出错

//For testing use DocURL = "res://shdocvw.dll/http_404.htm#https://www.microsoft.com/bar.htm"
DocURL=document.URL;

//this is where the http or https will be, as found by searching for :// but skipping the res://
protocolIndex=DocURL.indexOf("://",4);

//this finds the ending slash for the domain server
serverIndex=DocURL.indexOf("/",protocolIndex + 3);

//for the href, we need a valid URL to the domain. We search for the # symbol to find the begining
//of the true URL, and add 1 to skip it - this is the BeginURL value. We use serverIndex as the end marker.
//urlresult=DocURL.substring(protocolIndex - 4,serverIndex);
BeginURL=DocURL.indexOf("#",1) + 1;
urlresult=DocURL.substring(BeginURL,serverIndex);

//for display, we need to skip after http://, and go to the next slash
displayresult=DocURL.substring(protocolIndex + 3 ,serverIndex);
document.write( '' + displayresult + "");
}
//--&gt
