[Help] Disable Alt + F4

[___x][GooD.]

Hi, Im doing a program to block my computer with a login system..
But the only way to close it its alt + f4 (You cant close it by taskmanager.)
How can i disable the alt+ f4?

Ummmm You have to edit the event of alt f4 like this

Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
        '  Code to Override the Alt-F4 keys combination
        If e.KeyData = Keys.Alt + Keys.F4 Then
            'nothing
        End If
    End Sub

my guess..but I'm a noob

Edit: You forgot about Window's button

Hey that didn worked like you said..
And i didn forgot the windows button xD the border is none..

If we cant block alt f4..can you block everything without the enter key?

Windows will over ride that easy

add this to a timer (1 milisec)

Me.topmost = true

then it wont minimize at all

I had a waayy better one but I deleted it I'll try to redo it and get back to ya

Edit: Got it Follow this Works very well

Ok, In form load (important!) you need to enable key preview

  Me.KeyPreview = True

Then under the Form Key_Down Event add

 If e.KeyData = Keys.Alt + Keys.F4 Then
            e.Handled = True
        End If

That's it, a lot of ppl forget (including online resources) the Key_Preview has to be enabled.

Thanks alot it worked NextGen... I can do the same with Alt tab or win + l ..That things?
If i can, can you say me how i use the Select Case with that=?

Yes You can, Windows Key is Private Const VK_LWIN As Byte = &H5B

use keys.lwin.
