Hi Sherm,

To select all text in an Edit Control, you will need to send an EM_SETSEL
message to the control.

Win32Lib provides 'sendMessage( control, command, wParam, lParam )'.

In this case, wParam is the starting position (nStart) and lParam is the
ending position (nEnd). If the nStart parameter is 0 and the nEnd parameter
is =961, all the text in the edit control is selected. If nStart is =961, an=
y
current selection is removed. The caret is placed at the end of the
selection indicated by the greater of the two values nEnd and nStart.

You don't need to define EM_SETSEL because it is already defined in
Win32Lib.

Hope this helps.  (I'm not sure if this is what you are asking but there
are many other Edit control messages that should help you do what you want.)=
