How do I capture mouse and keyboard events?
1. The Win32API Reference Help File says like this:
The system hooks are a shared resource, and installing one affects all
applications. All system hook functions must be in libraries. System hooks
should be restricted to special-purpose applications or to use as a
development aid during application debugging.
2. There is no hWnd param for SetWindowsHookEx... Declare for
SetWindowsHookEx:
Public Declare Function SetWindowsHookEx Lib "user32" Alias
"SetWindowsHookExA" (ByVal idHook As Long, ByVal lpfn As Long, ByVal hmod As
Long, ByVal dwThreadId As Long) As Long
There is no hWnd param...
