Error handling for ASP based sites and forms

I'm working on a asp based (not .net) site, which spans about 400 odd pages... Now, throughout the site there're ASP and VBScript errors, such as:

Microsoft VBScript runtime e开发者_StackOverflow社区rror '800a000d'

Type mismatch: 'Cdate'

/MySite/page.asp, line 71

(The above happened when I put in characters into a 'date' field. I know its VBScript in this case, but I get plenty all over.)

Now, I know I can avoid this scenario with client side validation (jQuery for example), but when such things do happen, how do I code up a default 'error' page? You hit the error, and instead of showing you the above, you get redirected to a generic 'error' page?

I've looked up some of this, and found the ASP 'On Error Resume Next' thing, but I haven't found any viable examples. Each one is tailored to a specific error (like dividing 5 by 0), and I really don't want to code up like 400+ potential error messages.

You could create custom error pages, via IIS. I'm not sure what version you're running, etc - but this should give you a good jumping off point. http://support.microsoft.com/kb/224070

You add following code in top in your page.

    <% on error resume next%>

.
..
....

(Other code is above instead of point(.))

Then you add

<% if err then
response.redirect("err.page?code="&err.code)
end if%>

And you define error message in your generic error page according to error number.

if you ask same question for client side. You can try and catch code block for possible code clock that will can throw.

For examle

<script language="text/javascript">
try
  {
//Code that will can throw error is here. 
  }
catch(err)
  {
 document.href.location="genericerrorpage.asp?err=" + err.code;


  }
}

</script>
