Hi Jaime

>How can i have move the cursor to the beginning of a field automatically?

You need to control the SELSTART property of the textbox, as Vlad told you.

However, due to the quirks of VFP's sub classing and base class behavior I have found that the only truly reliable (in all situations and all levels of class hierarchy) way of handling this is to include the following code in the GotFocus() of your textbox class:

*** Explicitly call base class behavior
TextBox::GotFocus()
WITH This
  *** Set insertion point
  .SelStart = 0
  IF .SelectOnEntry
    *** Highlight contents
    .SelLength = 999
  ENDIF
ENDWITH
*** Suppress normal base class behavior
NODEFAULT

Notice that this also highlights the contents when the native 'SelectOnEntry' property is set. If you don't want it, remove the code.
