-
- HOWLONG.DLL - A DLL containing routines that track the last time that

-
- 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.
