SAMPLE: Windows Journal Hooks Sample Source Code

• Microsoft Windows Software Development Kit (SDK) for Windows versions 3.0 and 3.1

SUMMARY

JOURNAL is a file in the Software Library that contains sample code to demonstrate the use of the journal hooks WH_JOURNALRECORD and WH_JOURNALPLAYBACK. The JOURNAL archive file contains the source to APP.EXE; WNDPROC.C is one of the source files.

The APP.EXE application serves only one purpose; it illustrates how to call the dynamic-link library (DLL) that performs all of the journaling work. The WNDPROC.C application module contains calls to the DLL to record and play back messages. One of the source modules for the DLL, JOURNAL.C, contains all the code required to create DIARY.BIN, a file of messages. The messages in DIARY.BIN can be played back at a later time. The DIARY.BIN file is overwritten each time the user chooses Record On from the menu.

The JOURNAL code can serve as the basis of a "hands off" application demonstration. The application demonstrating itself can call the high- level functions in the DLL to play each event.

The DIARY.BIN file is also included in the JOURNAL archive to demonstrate using journal hooks. To demonstrate playing the contents of a DIARY.BIN file, select Play from the menu.
