ctrl ---> 17
alt ---> 18

you can have it on a text box if you write in some other controls KeyDown event something like

textbox1.text = keycode

then just select that control an press the key you want to know ;)

These keys don't have ASCII codes.

ASCII defines values for the character set. These are keyboard keys, not characters.

The difference between KeyDown and KeyPress events is that one reports the actual key pressed, while the other reports the ASCII character which was generated as a result. For example, pressing the "A" key generates the keycode for that key (65). Depending on the current state of the Caps-Lock, Shift, Control and Alt and Shift keys, the ASCII character generated might be...

"A" (code 65), "a" (code 97), "Ctrl-A" (code 1) or whatever.

This is why keys such as Shift, Alt and so on do not trigger a KeyPress event.

You can try Key down and key up event using

KeyCode = vbKeyControl ==>> Control
KeyCode = vbKeyMenu ==>> Alt

there you find two perameter for key pressed and shift pressed

I think this will help you.

Are you sure you can't do it in the KeyDown or KeyUp event?

If you want, you can put code in your KeyPress event procedure to test the current state of these keys. I forget how, but detecting the current state of keys was covered here not too long ago. Maybe a couple of months back. Try some searches.

Hi,

U have to check the Shift in KeyUp event :
Values would be:
A C S
4 2 1

[code=vb]
Private Sub Text1_KeyUp(Key Code As Integer, Shift As Integer)
Select Case Shift
Case 1
MsgBox "Shift Pressed"
Case 2
MsgBox "Control Pressed"
Case 3
MsgBox "Shift + Control Pressed"
Case 4
MsgBox "Alt Pressed"
Case 5
MsgBox "Alt + Shift Pressed"
Case 6
MsgBox "Alt+Contro l Pressed"
Case 7
MsgBox "Alt+Shift+Cont rol Pressed"
End Select
End Sub
[/code]

There's also an API function you can call to check the current key state. I just don't remember what it's called.

It certainly would. If I could remember it. I do remember it had "Asynch" in the name, but that's probably not a lot of help.

Ok, I spent some time searching, and managed to track down the thread I was thinking of. Here it is.

I hope it's some help.

In my first post i wrote what the KeyCode were, and as Killer said, they dont have an ascii code, only a KeyCode. (the keycodes are 17 and 18), and im not sure they'll work in keypress, you should use them in keydown

Thanks to all of you, but after reading through all that I think we will come to an agreement that space bar (32) will be much easier to deal with

thanks to you all again
