500-100.asp Returns "Type Mismatch" Error After Request.BinaryRead() Method

ID: Q244758

The information in this article applies to:

Microsoft Internet Information Services version 5.0

SYMPTOMS

When an ASP page that uses the Request.BinaryRead() method generates an error and control is passed to the 500-100.asp error page, the following error is generated:

Microsoft VBScript runtime error '800a000d'
Type mismatch: 'Server.HTMLEncode'
/iisHelp/common/500-100.asp, line ...

CAUSE

This error is generated because the POST information from the Request.BinaryRead method returns an array, whereas the Server.HTMLEncode method in the 500-100.asp page expects a string to be passed.

WORKAROUND

The default 500-100.asp error page can be modified to ignore errors by adding an "On Error" statement:

Open Windows Explorer.

Change folders to your %SystemRoot%\help\iishelp\common folder.

Open 500-100.asp in Notepad.

The top lines of the file should resemble the following:


<%@ language="VBScript" %>
<%
  Option Explicit

  Const lngMaxFormBytes = 200

Change the top few lines to read the following:


<%@ language="VBScript" %>
<%
  Option Explicit
  On Error Resume Next

  Const lngMaxFormBytes = 200

MORE INFORMATION

The following steps reproduce this error on a server that is using the default, unmodified 500-100.asp error page:

Save the following code as ERRTEST1.ASP in the root directory of your Web site:


<html>
<head><title>Page 1</title></head>
<body>
<form action="errtest2.asp" method="POST">
<input type="text" name="test">
<input type="submit">
</form>
</body>
</html>

Next, save the following code as ERRTEST2.ASP in the root directory of your Web site:


<%@LANGUAGE="VBSCRIPT"%>
<html>
<head><title>Page 2</title></head>
<body>
<%
  Dim vntPostedData, lngCount, lngError
  lngCount = Request.TotalBytes
  vntPostedData = Request.BinaryRead(lngCount)
  Response.Write "POST Size: " & lngCount
  lngError = 1/0
%>
</body>
</html>

Browsing page 1 and submitting information to page 2 should return an error message like the following:

Error Type: Microsoft VBScript runtime (0x800A000B) Division by zero /errtest2.asp, line 10

Browser Type: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)

Page: POST 9 bytes to /errtest2.asp

POST Data: Microsoft VBScript runtime error '800a000d' Type mismatch: 'Server.HTMLEncode' /iisHelp/common/500-100.asp, line 184
