Configuring the Web Server

C-6

Falcon

4400 Series with Windows

Creating and Using an ISAPI Service

Developers can create an ISAPI service written in eVC++ to access the APIs

available on the Terminal. The two sample .dlls below demonstrate setting and

getting a few of the configurable items available in the Falcon 44xx SDK.

Setting Configuration Items

The following example shows how to set the Code 39 minimum label length

to 10 characters:

1. Create a virtual directory under the root called SetSym and set the

Default registry entry to SetSym.dll while making sure the full

path is included.

[HKEY_LOCAL_MACHINE\COMM\HTTPD\VROOTS\/SetSym]

@="\\windows\\SetSym.dll"

2. Restart the Web Server as described on page C-2.

3. Enter the following information into Internet Explorer on the Termi-

nal or host PC:

http://<ip address of Terminal>/SetSym?CD39MIN&10

Getting Configuration Items

The following example demonstrates how to get all the settings for Code 39:

1. Create a virtual directory under the root called GetSym and set the

Default registry entry to GetSym.dll while making sure the full path is

included.

[HKEY_LOCAL_MACHINE\COMM\HTTPD\VROOTS\/GetSym]

@="\\windows\\GetSym.dll"

2. Restart the Web Server as described in the first section. (C-2)

3. Enter the following information into the Internet Explorer on the

Ter m i n a l o r de s k t o p c o mpute r :

http://<ip address of Terminal>/GetSym?C39

These two samples are only the beginning of what can be accomplished with

the Web Server. Please note that ISAPI is currently the only method of server-

side method invocation. Please consult the Help file associated with the SDK

and eVC++ for more information on ISAPI and Web Server features.
