low level keyboard hook in a extra class. But it seems that the
Parameters are not passed correctly to my Hook function. Similar
Examples in VB .NET work correctly.
Heres the Source Code:
using System;
using System.Runtime.InteropServices;

is showing. So I installed a keyboard hook, but now whenever a key is
pressed when the menu is showing, the application crashes and sometimes
throws a NullReferenceException in system.windows.forms.dll. I assume

When I try to hook a non letter key like left arrow (37) all is OK.
If (Hookstruct.vkCode = 37) Or (Hookstruct.vkCode = 83) And
CBool(Hookstruct.flags) Then

In a dialog box procedure is there a way to determine if keyboard input is
from the keypad or the arrow keys?
I need to know if the input is from the main keyboard keys.

Is it possible to do a local keyboard hook to a process running in a
new thread. The process is a command line application and is
instanciated when a button is pressed on the main form. I have had the
hook working Globally, but this means that the hook logs keystokes
from the main app as well as the keystrokes fom the CMD process. The
hook is...
