HOWTO: Use VFP Automation Servers with Active Server Pages
ID: Q168053

The information in this article applies to:
-
Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a, 6.0
SUMMARY
Microsoft Internet Information Server (IIS) 3.0 supports Active Server
Pages (ASP). ASPs allow you to perform server-side processing and scripting
through the use of automation servers, including automation servers that
were created in Visual FoxPro 5.0 or 6.0. This article demonstrates how to
use a Visual FoxPro automation server with Active Server Pages.
MORE INFORMATION
There are primarily two components:
- Visual FoxPro Automation Server.
- Active Server Page that instantiates the server.
The Visual FoxPro Automation Server
For this example, you can create a simple automation server in Visual
FoxPro. This automation server has two methods: one called GetTime(), which
will return the current time and one called GetDate(), which will return
the current date.
Creating the automation server:
- Create a new project named ASPSrv in Visual FoxPro.
- Add a new program to the project with the following code:
DEFINE CLASS WristWatch AS Custom OLEPUBLIC
PROCEDURE GetTime()
RETURN Time()
ENDPROC
PROCEDURE GetDate()
RETURN Date()
ENDPROC
ENDDEFINE
- Build the project into an OLE DLL automation server.
- Install the automation server onto your IIS 3.0 server.
NOTE: It is recommended that you use the Setup Wizard in Visual FoxPro
as a distribution method. Files that will be included for distribution
are the Visual FoxPro runtime, the OLE server .DLL, .TLB, and .VBR
files.
The Active Server Page
The ASP file is the component that instantiates the automation server and
calls the methods of the automation server.
- Create the following file in a text editor, such as Notepad:
<%@ LANGUAGE="VBSCRIPT" %>
<!-- Ensure that there is a space before LANGUAGE and
after "VBSCRIPT" -->
<HTML>
<HEAD>
<TITLE> VFP and ASP </TITLE>
</HEAD>
<BODY>
<H2>Active Server Pages and Visual FoxPro Automation Servers</H2>
<%Set VFPSrv = Server.CreateObject("ASPSrv.WristWatch")%>
Today's Date is <%=VFPSrv.GetDate()%>
<P>
The Current Time is <%=VFPSrv.GetTime()%>
</BODY>
</HTML>
- Save this file to your IIS WWWROOT directory as VFPSrv.ASP, and make
certain that this directory has Execute privileges.
- You should now be able to access this Active Server Page from your Web
browser. The page should show the current date and time from the server.
