BHO and keyboard hooks

hello,
I want to add a keyboard hook to my application.Thi s should be detected only
from IE.I searched on this and found the IEAccessible_fi nal_sem_doc in the
following link:
http://slappy.cs.uiuc.edu/fall03/team2/Final/index.html

I understand that i have to install the hooks using the SetWindowsHookE x
from within the IObjectWithSite :SetSite.
But i came across this line in the code...

explorer = (WebBrowserClas s)Marshal.Creat eWrapperOfType(
wba as SHDocVw.IWebBro wser,
typeof(WebBrows erClass));

I dont understand it.Also how is the HookProc getting called?i need to know
this so that i can modify it for my procedure.

please help me.I am lost.
thanks,
Priya

I'm working on an application (OEM) using C# that utilizes input from a keyboard, and USB Barcode Scanner. The scanner is a HID Keyboard device, and input from it is sent to the system as if it were a keyboard. I need to be able to identify input from the scanner and keyboard independently. I've looked at DirectX.DirectInput, and using user32.dll to hook into the keyboard messages, but neither method seems to allow for identification of...

Hi, in my application I want to react to certain keys when a context menu 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 that the hook somehow messes up the context menu's message loop or something like this. I also had this problem with a mouse hook, so i guess its a...

I have a Windows form application running that contains a button and textbox. An easy thing to do is to monitor the last time a keystroke was executed in the textbox. I can then click the button and it will say: "The last keystroke in the textbox was 10 minutes ago." This is not what I want to do. What I would like to see is a message that says: "The last keystroke in any running application on this computer was 23 minutes ago." My...

I have an application that minimizes itself, and I want it to listen for certain key commands, and when they are pressed, my program can react to them. So far I've gotten my application to react as I intend while the program has focus, but when the application loses focus, the listening stops. I am using VS 2008 beta 2, with .net 3.5.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
