setwindowshookex

I've been working on this one quite a bit and haven't gotten any closer to a solution. I juut dug up my old copy of the WindowsHookLib again - It's available with source at http://www.codeproject.com/KB/DLL/WindowsHookLib.aspx . This library allows Global Windows Mouse/Keyboard/Clipboard Hooks, which is very useful. I'm trying to use the Mouse Hook in here to Capture Mouse-Motion (I could use a Timer that always polls Cursor.Position, but I plan on using more features of WindowsHookLib later). Code as follows: MouseHook mh = new MouseHook(); mh.InstallHook(); mh.MouseMove += new EventHandler

Im trying to hook up to other windows from csharp. Im using SetWindowsHookEx , but no luck with converting it fom c++ t c#. I found this thread here but it wasnt solved. The problem is that SetWindowsHookEx returns 0. It includes best code samle i found: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace WindowDrawer { public partial class Form1 : Form { private delegate int HookProc(int code, IntPtr wParam, IntPtr lParam); static IntPtr hHook; IntPtr

I'm trying to set a low level windows keyboard hook to grab three keys pressed even if the application is not in focus. To do this I'm calling SetWindowsHookEx as // Create an instance of HookProc. KeyboardHookProcedure = new HookProc(KeyboardHookProc); //install hook hKeyboardHook = SetWindowsHookEx( WH_KEYBOARD_LL, KeyboardHookProcedure, Marshal.GetHINSTANCE( Assembly.GetExecutingAssembly().GetModules()[0]), 0); //If SetWindowsHookEx fails. if (hKeyboardHook == 0) { //Returns the error code returned by the last unmanaged function called using platform invoke that has the DllImportAttribute

I've created a GLOBAL keyboard hook DLL, using source code found on the internet. For the best part it works brilliant, except when it comes to browsers. It picks up every key in the browser except, it seems, when the browser gets focus, it looses the first key that is pressed. Tested this in IE and Firefox and it seems to be the same for both. For instance, if I open IE and start typing www. , I only get back ww. If the browser window stays in focus no further keys are lost. As soon as the browser looses focus and regains focus, the first key is again missing. Could it be because of using

I'm trying to use the Gma.UserActivityMonitor library in a project and I've faced an error I can not overcome on my own. In the HookManager.Callbacks.cs file there's a static method called EnsureSubscribedToGlobalMouseEvents with the following code (more or less): var asm = Assembly.GetExecutingAssembly().GetModules()[0]; var mar = Marshal.GetHINSTANCE(asm); s_MouseHookHandle = SetWindowsHookEx( WH_MOUSE_LL, s_MouseDelegate, mar, 0); //If SetWindowsHookEx fails. if (s_MouseHookHandle == 0) { //Returns the error code returned by the last unmanaged function called using platform invoke that has

We have some global keyboard hooks installed via SetWindowsHookEx with WH_KEYBOARD_LL that appear to randomly get unhooked by Windows. We verified that they hook was no longer attached because calling UnhookWindowsHookEx on the handle returns false . (Also verified that it returns true when it was working properly) There doesn't seem to be a consistent repro, I've heard that they can get unhooked due to timeouts or exceptions getting thrown, but I've tried both just letting it sit on a breakpoint in the handling method for over a minute, as well as just throwing a random exception (C#) and it
