Introduction to a sockets client

Refer to the documentation of your development environment for more information on sockets

programming.

The code sample shown in Figure 36: Sample socket client code on page 69 describes an

introduction for beginner programmers on how to build a very simple Visual Basic program that

contacts the DECT Messenger eKERNEL module and delivers a message request. Note that

the source code is provided for illustration only, and does not include error recovery.

Creating a basic sockets client using Visual Basic

1. Start Visual Basic, and open a new project of Standard .EXE type. In the menu,

choose Project > Components and add the Microsoft Winsock Control component

to the project. This component usually refers to C:\WINNT

\system32\MSWINSCK.OCX.

2. Drag a CommandButton control to the form. You can use the default name

Command1.

3. Drag a Winsock control to the form. You can use the default name Winsock1.

4. Add the code shown in

Figure 36: Sample socket client code on page 69 in the

Private Sub Command1_Click.

5. Specify the correct IP address (the IP address of the system where eKERNEL runs)

and port number (the configured port for eAPI, as defined in

eKERNEL_TCPCLIENT table).
