Thanks very much, I was able to implement it.
If someone wants the code, I will send it.

D> The Windows API call you will need is called 'GetGUIThreadInfo'. With this,
D> you can get the handle of the foreground (focus) control that has the
D> current caret.
D> Here some details from the Mircosoft SDK...
D> GetGUIThreadInfo
D> The GetGUIThreadInfo function retrieves information about the active window
D> or a specified graphical user interface (GUI) thread.
D> BOOL GetGUIThreadInfo(
D> DWORD idThread, // thread identifier
D> LPGUITHREADINFO lpgui // thread information
D> );
D> Parameters
D> idThread [in] Identifies the thread for which information is to be
D> retrieved. To retrieve this value, use the GetWindowThreadProcessId
D> function. If this parameter is NULL, the function returns information for
D> the foreground thread. lpgui [out] Pointer to a GUITHREADINFO structure
D> that receives information describing the thread. Note that you must set
D> GUITHREADINFO.cbSize to sizeof(GUITHREADINFO) before calling this function.
D> Return Values
D> If the function succeeds, the return value is nonzero.
D> If the function fails, the return value is zero. To get extended error
D> information, call GetLastError.
D> Remarks
D> This function succeeds even if the active window is not owned by the
D> calling process. If the specified thread does not exist or have an input
D> queue, the function will fail.
D> This function is useful for retrieving out-of-context information about a
D> thread. The information retrieved is the same as if an application
D> retrieved the information about itself.
D> Requirements Windows NT/2000/XP: Included in Windows NT 4.0 SP3 and later.
D> Windows 95/98/Me: Included in Windows 98 and later.
D> Header: Declared in Winuser.h; include Windows.h.
D> Library: Use User32.lib.
D> The GUITHREADINFO structure contains information about a GUI thread.
D> typedef struct tagGUITHREADINFO {
D> DWORD cbSize;
D> DWORD flags;
D> HWND hwndActive;
D> HWND hwndFocus;
D> HWND hwndCapture;
D> HWND hwndMenuOwner;
D> HWND hwndMoveSize;
D> HWND hwndCaret;
D> RECT rcCaret;
D> } GUITHREADINFO, *PGUITHREADINFO;
D> Members
D> cbSize Specifies the size of this structure, in bytes. The caller must set
D> this to sizeof(GUITHREADINFO). flags Specifies the thread state. This
D> member can be one or more of the following values. Value Meaning
D> GUI_16BITTASK Windows XP: Represents the thread's application type. This
D> bit is set if the thread corresponds to a 16-bit application.
D> GUI_CARETBLINKING Represents the caret's blink state. This bit is set if
D> the caret is visible. GUI_INMENU Represents the thread's menu state. This
D> bit is set if the thread is in menu mode. GUI_INMOVESIZE Represents the
D> thread's move state. This bit is set if the thread is in a move or size
D> loop. GUI_POPUPMENUMODE Represents the thread's pop-up menu state. This
D> bit is set if the thread has an active pop-up menu. GUI_SYSTEMMENUMODE
D> Represents the thread's system menu state. This bit is set if the thread is
D> in a system menu mode.
D> hwndActive Handle to the active window within the thread. hwndFocus Handle
D> to the window that has the keyboard focus. hwndCapture Handle to the window
D> that has captured the mouse. hwndMenuOwner Handle to the window that owns
D> any active menus. hwndMoveSize Handle to the window in a move or size loop.
D> hwndCaret Handle to the window that is displaying the caret. rcCaret A RECT
D> structure that describes the caret's bounding rectangle, in client
D> coordinates, relative to the window specified by the hwndCaret member.
