Latest revision as of 10:09, 7 April 2006

There are 3 different kinds of hooks now. Which one is better?

• 1.Old one in svn. Use WM_MOUSE.

   Problems:
   1. Does not work with pointer button pressed and when pointer moves outside the same process.
   2. Cursor will be changed outside the same process.

• 2.Wel hook with low level mouse hook (WH_MOUSE_LL) and normal hook (WH_MOUSE).

   Problems:
   1. Cursor will be changed outside the same process.
   2. Low level mouse hook does not work on Windows 98.

• 3.Wel hook with journal record hook (WH_JOURNALRECORD) and normal hook (WH_MOUSE).

   Problems:
   1. Cursor will change between our application's cursor and another processes cursor.
   2. Low level mouse hooks do not work on Windows 98.

• 4.Wel hook (heavy capture) and Windows setCapture (normal capture) working at the same time.

   Problems:
   1. Does not work when pointer button pressed and pointer move outside the same process EXCEPT the first time.
   Advantage:
   1. Actually, in most cases users only care about the first time when pointer button pressed.

• Final words:

   If I can find a way to stop Windows from changing mouse cursor, I think "2" is perfect. (But is still not supported by Windows98)
