转换ASP到ASP+

Converting to ASP+
The conversion process from ASP to ASP+ will depend on the complexity of your existing pages. Databases,
hence ADO, is a great example. ADO is now ADO+ and much different. Therefore if you want your database
pages to be ADO+ ASP+ pages, the learning curve is a little steeper. Your old code will work in most cases
with minimal adjustments (mainly structure).

Structure
The way you write your classic ASP pages will determine the level of technicality in converting your
classic ASP pages to ASP+. VBScript is a subset of VB but not the same as VB therefore minor changes,
mainly formatting, will be required. Structure will be the biggest issue. Get used to the Object Oriented
World. And get used to seeing cleaner code. VB and HTML coding must be separated where as with VBScript
you could intertwine it with HTML.

Mix and match HTML/VBScript
If you do this a lot inside your Functions and Subs,


<%
URL = request.servervariables("URL")
%>
<FONT FACE="arial" SIZE="2">
The URL was <%=URL%>


Then you have work to do. ASP+/VB does not allow ASP code to be mixed with HTML freely inside of functions
and Subroutines. They must be separated. In order for this to run in ASP+, all lines must be converted to
VB response.write statements. Not VBScript response.write statements. Notice the parenthesis. This will be
the most cumbersome part of converting ASP pages to ASP+ pages.

This would be the proper way with ASP+/VB


URL = request.servervariables("URL")
response.write ("<FONT FACE=""arial"" SIZE=""2"">)
response.write ("The URL was "& URL & "</FONT>")



Function Calls

With VBScript/ASP you write your functions like this

<%
Function doIt()
response.write ("Yes")
End Function


Function doIt2()
response.write ("Yes")
End Function%>


The following way is how you will need to write your functions in ASP+/VB. The most important thing here
is the <SCRIPT> tags.


<SCRIPT LANGUAGE="VB" RUNAT="server">

Function doIt()
response.write ("Yes")
End Function


Function doIt2()
response.write ("No")
End Function


</SCRIPT>
