Keypress event in RTF Textbox

[kamweng]

My keypress worked fine in a textbox but I could not make it work in a RTF textbox:

*** ActiveX Control Event ***
LPARAMETERS keyascii

IF keyascii = -8 && F9
MESSAGEBOX(0,0,0) && For example
ENDIF

RETURN

Is there anything else that I should be aware of?

Thank you.

The Keypress for an ActiveX control works differently from that of a native control. In particular, it does not work with the same key values. In the ActiveX control, you can only trap the "printable" ASCII characters, such as A - Z a - z, 0 - 9, etc. - not function keys such as F9.

If you need to trap function keys, use KeyDown instead:

*** ActiveX Control Event ***
LPARAMETERS keycode, shift

IF keycode = 120
	MESSAGEBOX("F9 was pressed")
ENDIF

Keypress return the ASCII code. -8 is not an ASCII code.

Use keydown / keyup instead

*** ActiveX Control Event ***
LPARAMETERS keycode, shift
IF keycode = 120 && F9
	MESSAGEBOX(0,0,"Ole!") && For example
ENDIF

Here is a list with keyboard key codes versus ASCII codes

Thank you for the replies.

I was wondering why RTF Textbox used LPARAMETERS keyascii whereas the normal Textbox used LPARAMETERS nKeyCode, nShiftAltCtrl.

Once again, thank you.

*** ActiveX Control Event ***

This hints for non native events always. ActiveX is always a non VFP thing and has its own rules.

Bye, Olaf.
