I have an app where I would like to highlight a section of text in an Edit box, I know how to highlight the whole text (by drawing the text), however am unsure as to how I can highlight a section.

Any Ideas?

Setting the properties SelStart and SelLength is the correct way to highlight text in a TEdit. See Delphi help for a sample.
If you use a Windows edit box then send a EM_SETSEL message to the control. See Windows SDK help.

hi,

try this:

// HighLightText(Edit1, 1, 3);
Procedure HighLightText(Edit : TEdit; nStart, nEnd : Integer);
Begin
 Windows.SetFocus(Edit.Handle);
 Edit.Perform(EM_SetSel, nStart-1, nEnd);
End;

Hello

  Try that by send message  EM_SETSEL

  Edit1.SetFocus;
  SendMessage(Edit1.Handle, EM_SETSEL, 2, 7);

Best regards
