Solution 1

First you get the window handle using the current point of the mouse using the method WindowFromPoint.
http://msdn.microsoft.com/en-us/library/ms633558%28v=vs.85%29.aspx[^]

And second you get the text of that window using GetWindowText:
http://msdn.microsoft.com/en-us/library/ms633520%28v=vs.85%29.aspx[^]

The code will become something like:

char[] buffer = new char[256];
GetWindowText(WindowFromPoint(pt.X, pt.Y), buffer, 256);

Good luck!

But when you paint the text on the canvas you aren't able to retrieve it because it is a drawing and not text. You need to handle WM_GETTEXT and store the text as property in your control.
LRESULT CALLBACK GetMesgProc(int nCode, WPARAM wParam, LPARAM lParam) {
PMSG pmsg;
if (nCode < 0)
return CallNextHookEx(hNextHook, nCode, wParam, lParam);
pmsg = (PMSG)lParam;
switch (pmsg->message) {
case WM_GETTEXT: / return the text
break;
};
return CallNextHookEx(hNextHook, nCode,wParam, lParam);
}

Solution 2

Just change the background color
in the intersection of your selection[^] and the text areas :)

MSIL

void GetFormattedData( PVOID pBuf,DWORD dwOffset, CString &szFormatted )
{
    BYTE *SETBUFF = ((BYTE*)(pBuf)) + dwOffset ;
    szFormatted.Format(_T("%08d: %.2X %.2X %),dwOffset,SETBUFF[0], SETBUFF[1],;
}

C#

for(int i = Start; i<= End; i++)
    {
        GetFormattedData(m_lpData, (i + m_nVScrollBarPos )* m_cyChar,szFormatted);
        m_pDC.TextOut((1 - m_nHScrollBarPos) * m_cxChar , i * m_cyChar, szFormatted);
    }

now i want the text to be selected using OnLButtonDblClk
