Killing Keys When Pressed

I was told that this would work to kill the processing of a tab key when it is pressed:

private sub text1_KeyDown (shift as integer, keycode as integer)
if keycode = 9 then 'tab key
keycode = 0
end if
end sub

It does not work however. Is there any way to kill it without sending a backspace or anything like that? I'm trying to make my tabs in a multiline text box 4 spaces instead of 8, but the tab is still sent after I send the four spaces. Any help will be rewarded with profuse thanks.

Code:

---

'You can set the Tabstop property to false for all the controls:
'disable the tab form

Private Sub Form_Load()
        Dim i As Integer
        On Error Resume Next
        For i = 0 To Controls.Count - 1  ' Use the Controls collection
                  Controls(i).TabStop = False
        Next
End Sub

---

I don't want to kill the tabstop, just the processing of a tab in the textbox. Tab doesn't change controls as it is, but it does insert 8 spaces. OnKeyDown, I would like to kill the tab and insert 4 spaces instead but I don't know how to kill the tab after I have captured it or any key for that matter. A similar example would be inserting "b" when the "a" key is pressed without sending a backspace to delete the a. I don't want the "a" to appear at all.

try returning the focus to the textbox with textboxname.setfocus

Apparently more background is needed. My main form is one huge textbox used for text editing. When the person hits tab at this point, 8 spaces are entered into the textbox. I would like to have a code that detects the tab and puts four spaces instead of 8. This is the code I used:

private sub text1_KeyDown(KeyCode as integer, Shift as Integer)

if keycode = vbKeyTab then
Text1.seltext = " "
KeyCode = 0
End if

Unfortunately, when the user pressed tab, it inserted my four spaces but then also inserted a tab (in the text box). I thought that the "keycode = 0" would cancel the tab so that only four spaces would appear, but I was wrong. Is there a way to do this?

I think you could use...

...the Text1_KeyPress Event

Code:

---

If KeyAscii = vbKeyTab Then
KeyAscii = 0
'MsgBox "TAB"
'Code for 4 spaces
End If

---

Did that help for ya?

I tried this just to test:

Private Sub form_KeyAscii(KeyAscii As Integer, Shift As Integer)
If KeyAscii = vbKeyS Then
KeyAscii = 0
Text1.SelText = "a"
End If
End Sub

And the output is "as" every time I hit the s key. How come it's not cancelling the "s"?

I meant:

Private Sub Form_KeyDown(...
...

What?

Did you copy & paste it? or did you just typed it?

Maybe that's the prob :) hehe

The error was in the retype, not the original. They need an embarrassed face in the icon selection.

In my application I typed "text1_KeyDown"

ok, KeyAscii means you have to enter the ASCII number for the number, so: S = 115
So use:

Code:

---

If KeyAscii = 115 Then
KeyAscii = 0
Text1.SelText = "a"
End If

---

That'll work

Please let me know if it works

It turns out the Ascii value for s is 83 so I tried that instead as you suggested. I still get "as" returned. I really appreciate the time you are taking to try to help me out. This is incredibly frustrating.

hmm the UCase(s) = 83 yes :)

but what isn't working then?
Please give me the code you're using... Wait I'll test it for ya one more time...

ok when I do:

Code:

---

Private Sub Text1_KeyPress(KeyAscii As Integer)
If KeyAscii = 83 Then
KeyAscii = 0
Text1.SelText = "a"
End If
End Sub

---

It just adds a to the text that's already in the box!
Damn I don't get it :(

It works for me when I press <Shift> + s

Damn I don't get it why it won't work for you... please test it with this code. :(

It's the difference between KeyDown and KeyPress apparently. When I copied and pasted your code it worked for me also. Thank you, Thank you, Thank you. Your name will go into the credits. :)

I would love it (you to put my name in the credits) but it's not neccesary, but again, no problem if you do :)

BTW, what does the prog?
