Included:
TESTDLL.EXE - a VB program that uses the HOWLONG.DLL routines to display
the time since last event, and the clock tick on which the
event occured.
TESTDLL.FRM - The VB program source for TESTDLL.EXE
TESTDLL.FRX
TESTDLL.MAK
HOWLONG.DLL - A DLL containing routines that track the last time that
the user moved the mouse or pressed a key.
License Statement:
This VB program, and the DLL that it calls, are property
of Malik Information Services. A license is granted to any and
all users who would like to include any portion of either
the VB program or the DLL into their code, under the condition
that any such user agrees that Nicklas Malik, Malik Information
Services, and any of its employees, affiliates, distributors, or
directors, are not liable for any damages, special, incidental,
consequential or otherwise, arising out of the use of these programs.
Installation:
Copy HOWLONG.DLL into your /WINDOWS/SYSTEM directory.
The following routines are defined in the DLL:
GetIdleTime - returns the tick count at the last mouse or keyboard event.
ResetIdleOnUser - Sets or clears a flag allowing WM_USER messages to be
considered to be a keyboard event for the purposes of GetIdleTime.
Full Descriptions:
GetIdleTime
C: DWORD FAR PASCAL GetIdleTime(void);
VB: Declare Function GetIdleTime Lib "HOWLONG.DLL" () As Long
Parameters: None
Function: When any of the following Windows Messages is sent, to any
task, a Windows Hook routine defined in HOWLONG.DLL will
record the return value of the Windows API call 'GetTickCount'.
WM_KEYDOWN
WM_LBUTTONDOWN
WM_MBUTTONDOWN
WM_RBUTTONDOWN
WM_NCLBUTTONDOWN
WM_NCMBUTTONDOWN
WM_NCRBUTTONDOWN
WM_MOUSEMOVE
WM_NCMOUSEMOVE
WM_USER + any non-negative value
The WM_USER messages are included because the MS-DOS prompt
Window does not use the ButtonDown messages, or, in fact, any
Keypress messages at all. When MS-DOS is displayed in a window,
and the user is typing, without using the mouse, Windows will
appear idle unless WM_USER messages are seen.
To tell the Hook routine to ignore User messages, see
the ResetIdleOnUser() routine, below.
Returns: The Windows Tick Count at last keyboard or mouse event.
-------------------------------------
ResetIdleOnUser
C: int FAR PASCAL ResetIdleOnUser(int bReset);
VB: Declare Function ResetIdleOnUser% Lib "HOWLONG.DLL" (ByVal bFlag%)
Parameters: bReset - Integer
Function: Allows the programmer to set or clear a flag used in the
detection of WM_USER events for GetIdleTime().
If the value of the 'bReset' parameter is Zero, then WM_USER
messages will be ignored by the GetIdleTime() routine. If the
value of 'bReset' is non-zero, then any Windows Message that
is greater than or equal to WM_USER will be sufficient to cause
the GetIdleTime() routine to save the Tick Count.
on Library initialization, WM_USER messages are seen.
Calls to this routine do not cause the GetIdleTime() tick
count to be reset.
Returns: The previous value of the IdleOnUser flag.
