[HELP] FormClosed in Checkbox

[expl0!t]

You want to make it where a user can't close the form?

      If CheckBox1.Checked = True Then
            Me.ControlBox = False
        Else
            Me.ControlBox = True
        End If

Would show/hide the control buttons (minimize, maximize, close).
Then just hide the program from taskmanager and use a work around to disable the alt+F4 key.

To block the alt+F4 from closing your program, import this code:

    Private frmval As Boolean = True

    Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown

        If (e.Alt) And (e.KeyValue = Keys.F4) Then
            e.Handled = frmval
        End If

    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        AddHandler Me.KeyDown, AddressOf Me.Form1_KeyDown

    End Sub

Then when you'd like to block the alt+f4 input, call this:

        frmval = True 'disables alt+f4
        AddHandler Me.KeyDown, AddressOf Me.Form1_KeyDown

Use Form_Closing event to do this.

This should be the code for your Form_Closing event:

Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
        e.Cancel = True
End Sub

To enable closing just set it to False:

e.Cancel = false

Hope this helps !!

how I can hide it from task manager ?
sorry for the copy & past questions

taskmanager must be still openable but the process must be hidden

I don't think anyone is going to help you do this. It sounds too much like malware/viruses/keyloggers where you need it to run undetected by anything in order to rape the shit out of a person's keyboard. There is no "legit" reason why you would need to make your program concealed at runtime.

Harder than it sounds.

It has to be a service, instead of a process.

(no code for you)
