Select all text when mouse click in an Edit Box

Is there a way in C++ to select all data in a control (TEdit), when the OnEnter event fires?  If the user TAB's into the field all data is automatically selected, but if they click in the field the | cursor is simply inserted where they clicked, I would like to have the OnEnter select all text in the control, so the mouse click works as the TAB does.

I have already tried (to no avail):
FieldName->SelStart =0;
FieldName->SelLength = FieldName->Text.Length();

I also tried the following 2 variations:
SendMessage(FieldName->Handle, EM_SETSEL, 0, -1);                  
SendMessage(FieldName->Handle, EM_SETSEL, 0, FieldName->Text.Length());                  

I use C++Builder v6 if that matters

It seems that even if you call the onenter event when you click into the tedit the internal onclick is fired for last (so the cursor position is changed).
Have you tried writing your code into the OnMouseDown event instead?

I have not attempted to use any OnMouse event, but will explore that avenue and post back.

Thank you Ferruccio68. Your suggestion led to the solution I will employ.

On Enter
//Set a global variable that field has been entered
  bGlobalFeildEntered = true;

On Exit
  bGlobalFeildEntered = false;

On Mouse Down
if (bGlobalFeildEntered)
  bGlobalFeildEntered = false;
  SendMessage(FieldName->Handle, EM_SETSEL, 0, -1);
