“HTTP Error 404 – File or Directory not found” error message when you request dynamic content with IIS 6.0

I ran across this problem with an ASP page and found a solution on the Microsoft Support site.

Active Server Pages (ASP) page, ASP.NET page, Internet Services API (ISAPI) application, or Common Gateway Interface (CGI) application on a Windows Server 2003 server running Internet Information Services (IIS) 6.0, give the following error messages:

  1. HTTP Error 404 – File Not Found
  2. HTTP Error 404 – File or Directory not found

IIS 6.0 was set to serve only static HTML pages by default on Windows Server 2003

Using the IIS manager Allow Active Server Pages under the Web service extensions node.

String Functions (Len, Left, Right, Mid)

dim myvar
myvar = "1234567"

response.Write(myvar & " is the variable<br/>")
response.Write(len(myvar) & " characters long<br/>")
response.Write(left(myvar,3) & " are the <b>left</b> three characters<br/>")
response.Write(right(myvar,3) & " are the <b>right</b> three characters<br/>")
response.Write(mid(myvar,3,3) & " : Mid(MyString, StartPos, NumChars)<br/> %>


1234567 is the variable
7 characters long
123 are the left three characters
567 are the right three characters
345 : Mid(MyString, StartPos, NumChars)

ASP: Find the length of a string using len and lenB function

my_string="Welcome to"
Response.Write ( my_string )
Response.Write "Length of this string = " & len(my_string)
Response.Write "Number of bytes Required for this string = " & lenB(my_string)

The output of this will also show the number of bytes required. Here in this case it will print this:

Welcome to
Length of this string = 21
Number of bytes Required for this string = 42
