Hiding caret in RichEdit winapi - c++

Question

I would like to hide a caret from a RichEdit(50W) with ES_READONLY style specified.
It's pretty confusing for the user, when the caret is blinking and the user can't type.
I tried to hide the caret using HideCaret() function,
however it doesn't work for me with following code:
LRESULT CALLBACK ChatMessaegsSubclassProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) // Subclassed control
{
LRESULT ret = CallWindowProc(WndProc_ChatMessages, hwnd, msg, wParam, lParam);
switch(msg)
{
//Also tried with EN_SETFOCUS
case WM_SETFOCUS:
{
ret = CallWindowProc(WndProc_ChatMessages, hwnd, msg, wParam, lParam);
HideCaret(ChatMessages); //Returns 5 (Access denied.)
break;
}
//According the documentation:
//If your application calls HideCaret five times in a row,
//it must also call ShowCaret five times before the caret is displayed.
case WM_KILLFOCUS: //The message is called when the RichEdit get focus, however nothing happens.
{
ret = CallWindowProc(WndProc_ChatMessages, hwnd, msg, wParam, lParam);
ShowCaret(ChatMessages);
break;
}
}
return ret;
}

Here is the solution:
LRESULT CALLBACK ChatMessaegsSubclassProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
LRESULT ret = CallWindowProc(WndProc_ChatMessages, hwnd, msg, wParam, lParam);
switch(msg)
{
case WM_LBUTTONDOWN:
{
HideCaret(ChatMessages);
break;
}
case WM_KILLFOCUS:
{
ShowCaret(ChatMessages);
break;
}
}
return ret;
}
NOTE this only works when user induces the focus with mouse. Therefore if anyone knows how to deal with it correctly, feel free to answer, I'll be glad.
