用Server.getLastError()的疑问

hehongyu2000 2001-11-22 08:28:15

为什么我用Server.getLastError()得到的ASPError对象属性值全是空或0.
win2000
IIS5
IE6.0
--------- Sample ---------------------------
<%@ Language=JavaScript %>
<%
try {
if (something == nothing) then //Error statement
}
catch(e) {
Response.write(Server.getLastError().ASPDescription()); //Show error description
}
%>
<HTML>
<HEAD>
<META NAME="GENERATOR" Content="Microsoft Visual Studio 6.0">
</HEAD>
<BODY>

<P> </P>

</BODY>
</HTML>

当然可以就像hehongyu2000说的那样啊，可以直接用Server.GetLastError()来取得

Frankly, the sample that I posted is a sample of "Programming Microsoft Windows 2000 Unleashed". If you have that book, you can review it. The sample in that book used try/catch to get ASPError. On the other hand, if I don't use try/catch to get error, how can I show the error message accoring to ASPError object. Thanks.

I think when you use try/catch, the error will be exposed through the parameter of catch(ex) and the ASPError object is cleared

I have tried, above is the result.You see only your first line has error message, second and third have nothing. Do you have any idea about it.
I think there is some tricks. Because when a ASP existed error, IIS will call 500-100.asp to show detail error message, in 500-100.asp, Server.GetLastError() return a valid ASPError object. why I can't get the object myselect by call Server.GetLastError(). Thanks.

try

Response.write(e.description + "<br>");
Response.write(Server.GetLastError().Description + "<BR>");
Response.write(Server.GetLastError().ASPDescription);
