KeyPress Event & Ctrl+Right Arrow?

[diarmaid]

I can't seem to detect when Ctrl+Right Arrow keyboard combination is pressed.

In the following nKeyCode & nShiftAltCtrl are the same whether you press Crtl+RightArrow or Ctrl+F ? Also, in the VFP9 Help I notice that INKEY() has a Ctrl value of "2" for both Ctrl+B key press and Ctrl+RightArrow key press.

Any enlightenment ?

CASE nKeyCode=27 && ESC was pressed
thisform.Release

CASE nKeyCode==1 AND nShiftAltCtrl==2 && Ctrl + Left
thisform.btnPrevious.Click

CASE nKeyCode==2 AND nShiftAltCtrl==2 && Ctrl + Right
thisform.btnNext.Click

CASE nKeyCode==6 AND nShiftAltCtrl==2 && Ctrl + F
thisform.btnSearch.Click

CASE nKeyCode == 107 && Alt + F4
thisform.btnExit.Click

I do similar keytrapping in my forms. To test for keys I have a form called SHOWANSI. It is a blank form with the command ? LASTKEY in the KEYPRESS event. To test for control keys I changed it to:
LPARAMETERS nKeyCode, nShiftAltCtrl
? LASTKEY()
? nKeyCode
? nShiftAltCtrl

It says that :
CTRL LEFT ARROW nKeyCode = 26 and nShiftAltCtrl = 2
CTRL RIGHT ARROW nKeyCode = 2 and nShiftAltCtrl = 2

Also make sure that you have the form's KEYPREVIEW property set to TRUE

I hope this helps

I'm not seeing the same as either of you.

I get 2 for Ctrl+Right and 26 for Ctrl+Left.

Actually, it varies according to whether you are using the numeric keypad or the cursor keypad. And if you're using the numeric keypad, it depends on whether NumLock is on.

First is the forms keypreview set to .t. and is your code in the keypress event?
for Ctrl + f you do not need to read the "nShiftAltCtrl" as the combination of Ctrl + f = 6

CASE nKeyCode = 6 && Ctrl + f
thisform.btnSearch.Click()

Imaginecorp - that is true, however the End key also returns 6 so you would need to test nShiftAltCtrl to see which key/combination the user pressed.

I get the following:

             nKeyCode  LASTKEY()
Ctrl+f     :    6         6
Ctrl+Right :    2         2
Ctrl+b     :    2         2
Ctrl+Left  :   26        26

So LASTKEY() is actually LASTKEYCOMBINATION

Is there then a way to tell between Ctrl+b and Ctrl+Right??

Stewart: You have me stumped. We do not use lastkey() etc

You are right:
Ctrl+b is the same as Ctrl+Right.so how do you tell which key was pressed.I am sure there is a way.

To make matters worse, Ctrl+b opens the Breakpoint pane for me.
I could get the Ctrl+f to work by using just nKeyCode.

This has got me intrigued, will work on it the minute I have some time and will report back.

You have to use Windows API functions for that. See
