Actually I developed not installed an add-in for Ms Word, in that add-in i am using keyboard hook event (lowlevel API) , keyboard hook event is working fine for Ms Word 2007/2010,
but in Ms Word 2013 that keyboard hook event is not working (does not trigger in Ms Word 2013).
The main keyboard hooks routine look like this:
private void SetKeyboardHook()
{
// Create an instance of the HookProc delegate.
keyboardHookProcedure = new HookProc(KeyboardHookProc);
using (Process curProcess = Process.GetCurrentProcess())
using (ProcessModule curModule = curProcess.MainModule)
{
hookHandle = SetWindowsHookEx(WH_KEYBOARD_LL, keyboardHookProcedure, GetModuleHandle(curModule.ModuleName), 0);
}
}
#region DLLImports
// Hook procedure callback type.
// SetWindowsHookEx is used to install a thread-specific hook.
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern int SetWindowsHookEx(int idHook, HookProc lpfn, IntPtr hInstance, int threadId);
// UnhookWindowsHookEx is used to uninstall the hook.
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern bool UnhookWindowsHookEx(int idHook);
// CallNextHookEx is used to pass the hook information to the next hook procedure in the chain.
[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
private static extern int CallNextHookEx(int idHook, int nCode, IntPtr wParam, IntPtr lParam);
// GetModuleHandle is used when calling SetWindowsHookEx for a keyboard hook.
[DllImport("kernel32.dll", CharSet = CharSet.Auto)]
private static extern IntPtr GetModuleHandle(string lpModuleName);
#region Nested type: HookProc
private delegate int HookProc(int nCode, IntPtr wParam, IntPtr lParam);
#endregion
private int KeyboardHookProc(int nCode, IntPtr wParam, IntPtr lParam)
{
// Per docs, if nCode < 0, the hook procedure must pass the
// message to CallNextHookEx function without further processing
// and should return the value returned by CallNextHookEx.
if (nCode < 0)
{
return CallNextHookEx(hookHandle, nCode, wParam, lParam);
}
if ((wParam == (IntPtr) WM.KEYDOWN) || (wParam == (IntPtr) WM.SYSKEYDOWN))
{
// The lparam that Windows passes us is a pointer to a KbDllHookStruct.
var kbDllHookStruct = (KbDllHookStruct) Marshal.PtrToStructure(lParam, typeof (KbDllHookStruct));
// -- Contrl + C Press Key Hook
if ((Control.ModifierKeys & Keys.Control) == Keys.Control && kbDllHookStruct.vkCode == (int) Keys.C)
{
//do something when Ctrl + C key Press
}
// -- Shift + Enter Press Key Hook
else if ((Control.ModifierKeys & Keys.Shift) == Keys.Shift && kbDllHookStruct.vkCode == (int)Keys.Return)
{
}
// -- Control + Enter Press Key Hook
else if ((Control.ModifierKeys & Keys.Control) == Keys.Control && kbDllHookStruct.vkCode == (int)Keys.Return)
{
}
// -- Alt + Enter Press Key Hook
else if ((Control.ModifierKeys & Keys.Alt) == Keys.Alt && kbDllHookStruct.vkCode == (int)Keys.Return)
{
}
else if ((Control.ModifierKeys & Keys.Alt) == Keys.Alt && kbDllHookStruct.vkCode == (int)Keys.Tab)
{
}
// -- Enter Press Key Hook
else if (kbDllHookStruct.vkCode == (int) Keys.Return)
{
try
{
//do something when EnterKey Press
}
catch
{
}
}
// -- Shift + Tab Press Key Hook
else if ((Control.ModifierKeys & Keys.Shift) == Keys.Shift && kbDllHookStruct.vkCode == (int) Keys.Tab)
{
try
{
//do something when Shift + Tab key press
}
catch
{
}
}
// -- Tab Press Key Hook
else if (kbDllHookStruct.vkCode == (int) Keys.Tab)
{
try
{
//do something when tabkey press
}
catch
{
}
}
else if (wParam == (IntPtr) WM.SYSKEYDOWN && kbDllHookStruct.vkCode == (int) Keys.F11)
{
return 1;
}
}
var callNextHookEx = 0;
try
{
// Ensure that we don't break the hook chain.
callNextHookEx = CallNextHookEx(hookHandle, nCode, wParam, lParam);
}
catch{}
return callNextHookEx;
}
The Above code is properly working in Word 2007/2010, but this is not working in Word 2013.
