Sample Code Information

Universal Web Connect provides example applications using Universal Web Connect and the Universal Web Connect API. The applications and libraries are located in the $INFORMIXDIR/samples directory.

WCSAMPLE--Daemon Example

The WCSAMPLE sample application uses all of the major functions of the Universal Web Connect API contained in the wclib.lib library. This application is similar in functionality to the WCDAEMON application that is shipped with Universal Web Connect, excluding the more sophisticated event handlers and the ability to write and update large objects.

The files include:

• wclib.h--the header file for the externally available Universal Web Connect API library functions
• wclib.lib--the library containing the Universal Web Connect functions
• wcsample.c--the sample application described below, which provides an example of how to use the Universal Web Connect APIs
• wcsample.mak--the makefile for building the WCSAMPLE application

WCSAMPLE provides the following functions:

• SampleEventHandler--a simple, sample event handler that shows how to use event-handlers within Universal Web Connect
• loadAppPage--a function that reads and loads AppPages stored and managed in the database
• loadLargeObject--a function that reads and loads large objects (images, documents, and so on) stored in the Informix database
• requestLoop--a function that handles HTTP requests made directly to the application either from the Universal Web Connect Driver (wcdrvr.exe) or directly from the Web browser (when in direct connect mode)

QWIN--Query Window Example

The QWIN sample application demonstrates a Universal Web Connect custom application with a set of AppPages that uses AppPage tags and user dynamic tags. QWIN also uses INFORMIX-ESQL/C.

To run the QWIN application

1. Build qwin.exe using qwin.mak.
2. Execute the following statement to populate the AppPages and user dynamic tags into the database:

    setupqwin database server username password 

1. Add the application section into the Universal Web Connect configuration file for qwin.exe.
2. Launch qwin.exe through your Web browser. See qwin.ec for a list of functions and comments.

The files include:

• reame.txt - the README file containing information about the QWIN example
• qwin.ec - the source file containing the functions and comments that make up the query window application
• qwin.mak - the makefile for building the QWIN sample application
• setupqwin.bat - the batch file to populate the database with AppPages and user dynamic tags
• app_pages/*.sql - the AppPages that are executed in the query window application
