 WM_QUEUESYNC

The WM_QUEUESYNC message is sent by a computer-based training (CBT) application to separate user-input messages from other messages sent through the WH_JOURNALPLAYBACK Hook procedure.

Return Value

A CBT application should return zero if it processes this message.

Remarks

Whenever a CBT application uses the WH_JOURNALPLAYBACK Hook procedure, the first and last messages are WM_QUEUESYNC. This allows the CBT application to intercept and examine user-initiated messages without doing so for events that it sends.

If an application specifies a NULL window handle, the message is posted to the message queue of the active window.

Notification Requirements

• Minimum DLL Version None
• Header Declared in Winuser.h, include Windows.h
• Minimum operating systems Windows 95, Windows NT 3.1
