Running DBWizard

i!-Database Plus and DBWizard

File Tab

The options under the File tab allow you to control the NetLinx code (AXI file) and database server

script (ASP file) that will be generated. The options are:

ASP File

Webserver Host name or IP Address

Webserver IP Port

Webserver Path

Absolute Database Path

NetLinx AXI File

NetLinx Local IP Port

NetLinx Code Prefix

Encapsulate

Once all these values are populated, you can select

Generate Code

from the Tools menu to

generate the code. Four new files will be created:

The automatically generated ASP and AXI files

NetLinxDBInclude.ASP and NetLinxDBInclude.AXI

These files include the helper function that the generated ASP and AXI files rely on.

ASP file

This is the main database server script file and will be transferred to the web server when you are

finished.

If this file exists, you will be prompted to overwrite it.

Webserver host name or IP address

The address of the web server that is running the ASP file.

The NetLinx code will require this value in order to work. If you do not know the name or address

of the web server, you can use a place holder like "localhost" and change the AXI manually in

NetLinx Studio at a later time.

If you have access to the server, you can use the

winipcfg

command under

Windows 95/98 or

ipconfig

under Windows NT/2000 to get the IP address of the server.

If you change any of these parameters, a sample browser URL will be built for you in the

"Example Browser Path" window.

Webserver IP port

The Webserver IP port is a web server port, usually port

. Only unusual web server setups will

use another value. If 80 does not appear to work, contact your web server administrator for the

correct value.

If you change any of these parameters, a sample browser URL will be built for you in the

"Example Browser Path" window.
