SNPP Component

The SNPP control is used to send pages through the internet using the SNNP protocol. (NOTE: The following is a very short description. For more information, please consult the help files that come with the respective package.)

It is a client implementation of Simple Network Paging Protocol Version 3 as specified in RFC 1861. Service extensions level 2 are supported intrinsically and the user can access all of level 3 extensions.

SNPP allows, unlike SMTP, for immediate notification of message delivery, gives absolute flexibility over the content sent to the recipient, allows to specifying multiple choice responses, etc.

To send a message the ServerName, recipient's PagerId and Message properties should be filled out (at a minimum) and Action delivers the message.

The server's response is given in PITrail events and by the LastReply property. Customized commands may be sent using the Command property.

Optional properties include: CallerId, ServerPort and LocalHost

This control requires a Winsock 1.1 compliant TCP/IP stack. This means that the Winsock stack installed in the system must have a version of at least 1.1. In particular, Windows 95, 98, and NT machines with Winsock 2.0 are fully supported.

SocketHandle. The handle of the main socket used by the control.

WinsockInfo. Identifying information about the loaded Winsock stack.

WinsockLoaded. Loads and unloads Winsock on demand.

WinsockMaxDatagramSize. Size in bytes of the largest UDP datagram that can be sent or received.

WinsockMaxSockets. Maximum number of sockets available to a single process.

WinsockPath. The path to the Winsock DLL used.

WinsockStatus. The status of the Winsock stack.

EVENTS
