Hi,
I am doing wpf project in which i have do multiple activities at same time so i use background worker process for each activity. i use class library. and also uses code

C#

ActivityManager.MouseMove  += HookManager_MouseMove;
          ActivityManager.MouseClick += HookManager_MouseClick;
          ActivityManager.MouseUp += HookManager_MouseUp;
          ActivityManager.MouseDown += HookManager_MouseDown;

which gives me Error code 126:The specified module could not be found.

ActivityManager is a class as follows:

C#

public static class ActivityManager
    {
        public static event KeyEventHandler KeyDown;
        public static event KeyPressEventHandler KeyPress;
        public static event KeyEventHandler KeyUp;
        public static event MouseEventHandler MouseClick;
        public static event EventHandler<MouseEventExtArgs> MouseClickExt;
        public static event MouseEventHandler MouseDoubleClick;
        public static event MouseEventHandler MouseDown;
        public static event MouseEventHandler MouseMove;
        public static event EventHandler<MouseEventExtArgs> MouseMoveExt;
        public static event MouseEventHandler MouseUp;
        public static event MouseEventHandler MouseWheel;
}

Although, i have added all the references and intellisense working i still get "Error :126" i.e The specified module could not be found.

HookManager_MouseMove is a event which i specify at runetime for handling MouseMove event.

Please show the code that produces that error.

sachin Bhosale @ code 6-Jun-14 4:50am

private static void EnsureSubscribedToGlobalKeyboardEvents()
{
// install Keyboard hook only if it is not installed and must be installed
if (s_KeyboardHookHandle == 0)
{
//See comment of this field. To avoid GC to clean it up.
s_KeyboardDelegate = KeyboardHookProc;
//install hook
s_KeyboardHookHandle = SetWindowsHookEx(
WH_KEYBOARD_LL,
s_KeyboardDelegate,
Marshal.GetHINSTANCE(
Assembly.GetExecutingAssembly().GetModules()[0]),
0);
//If SetWindowsHookEx fails.
if (s_KeyboardHookHandle == 0)
{
//Returns the error code returned by the last unmanaged function called using platform invoke that has the DllImportAttribute.SetLastError flag set.
int errorCode = Marshal.GetLastWin32Error();
//do cleanup

//Initializes and throws a new instance of the Win32Exception class with the specified error.
throw new Win32Exception(errorCode);
}
}
}

Please be more specific. What you wrote is not enough.

I am using class library specified in at:

http://www.codeproject.com/Articles/7294/Processing-Global-Mouse-and-Keyboard-Hooks-in-C

and
code
if (s_KeyboardHookHandle == 0)
{
//See comment of this field. To avoid GC to clean it up.
s_KeyboardDelegate = KeyboardHookProc;
//install hook
s_KeyboardHookHandle = SetWindowsHookEx(
WH_KEYBOARD_LL,
s_KeyboardDelegate,
Marshal.GetHINSTANCE(
Assembly.GetExecutingAssembly().GetModules()[0]),
0);

gives me error 126

Replace it with

VB

s_KeyboardHookHandle = SetWindowsHookEx(
                    WH_KEYBOARD_LL,
                    s_KeyboardDelegate,
                        IntPtr.Zero,
                            0);

or try this
