Module - eDMSAPI

The module eDMSAPI consists of two separate programs. One program

is eDMSAPI and is written in Visual Basic. The other program is called

CSTA_Service.exe and is written in C++.

In general, both programs reside in the default directory C:\SOPHO

Messenger@Net\Exe, unless otherwise implemented in your environment.

Overview

eDMSAPI.exe

The eDMSAPI is the Visual Basic component of the eDMSAPI module.

The program communicates with two processes: the eKERNEL and

the CSTA Service. The eKERNEL is the central engine that centralizes

all database access and communication with input and output capable

modules.

The eDMSAPI communicates with both eKERNEL and CSTA_Service.exe

by means of TCP sockets. In both communications, eDMSAPI is a TCP

client software that connects to the two other components, acting as TCP

server software.

For external clients (eWEB), the eDMSAPI acts as a multiple socket

server.

At start up, eDMSAPI contacts the eKERNEL by means of a socket

connection. For the eDMSAPI module to locate the eKERNEL, the

eDMSAPI must start up with parameters that identify the eDMSAPI module

and locate the eKERNEL program. These parameters are provided to

eDMSAPI in the Properties section of the shortcut that initiates eDMSAPI.

This shortcut is usually located in the Windows Startup group (click Start

on the Windows task bar and choose Programs > Startup).
