How do I get a Help Button to automatically retrieve the help context
identifier from the last active control on a Delphi form ?

eg If I'm in an edit field and I press F1, then Delphi resolves the help
context identifier for me. How do I achieve the same thing using a
dedicated help button ?

ta

this will give you the current active child,

Then browse in VCL sources to retrieve the HELP identifier and call the
function:
     WinHelp (handle, HelpFile, Help_Context, IdH); { see WinAPI Help
file }

Hope this help,
        Philippe.

Don't think there's an automatic way to do this.

Seems like the following would work but I've never tried it. Say I have a
TEdit called Edit1 and a TButton called HelpButton,

Edit1.Exit
begin
 HelpButton.HelpContext := Edit1.HelpContext;
end;

Then, when your user presses the Help button, the correct HelpContext is
called.

Hope this helps.

Scott,
  The following should work (I only tried it under Delphi 1.0).  Use a
SpeedButton for your help button so that the focus does not change when you
click on it (I named it HelpButton).

procedure TForm1.HelpButtonClick(Sender: TObject);
begin
  Application.HelpContext(ActiveControl.HelpContext);
end;

Hope this helps!
