Hi Friends

Need your help i was trying to add a feature process protection it work perfect in framework 4 but when i try in framework 2.0 i am getting error on StopProcessProtection in event handler can u correct me what is wrong
error

Code:
Method 'Private Function StopProcessProtection() As Boolean' does not have the same signature as delegate 'Delegate Sub EventHandler(sender As Object, e As System.EventArgs)'.

Process protection

Code:
Imports System.Runtime.InteropServices
Public Class clsProcessProtect

    <DllImport("ntdll")> _
Private Shared Function NtSetInformationProcess(ByVal hProcess As IntPtr, ByVal processInformationClass As Integer, ByRef processInformation As Integer, ByVal processInformationLength As Integer) As Integer
    End Function

    Dim psStop As New EventHandler(AddressOf StopProcessProtection)
    Const iStop = 0
    Const iStart = 1
    Const ProcessPriorityClass = 29

    Public Sub New()
    End Sub

    Public Sub Start()
        StartProcessProtection(iStart)
        AddHandler AppDomain.CurrentDomain.ProcessExit, psStop
        AddHandler AppDomain.CurrentDomain.DomainUnload, psStop
        AddHandler Application.ApplicationExit, psStop
    End Sub

    Private Function StartProcessProtection(ByRef psInfo As Integer) As Boolean
        Try
            NtSetInformationProcess(Process.GetCurrentProcess().Handle, ProcessPriorityClass, psInfo, Marshal.SizeOf(psInfo))
            Return True
        Catch ex As Exception
            MessageBox.Show(ex.Message & vbNewLine & ex.InnerException.ToString())
        End Try

    End Function

    Private Function StopProcessProtection() As Boolean
        Try
            StartProcessProtection(iStop)
        Catch ex As Exception
            MessageBox.Show(ex.Message & vbNewLine & ex.InnerException.ToString())
        End Try
    End Function

End Class

Even Any one know How to bypass the process protection please share with me i will be thankful to you

i assume option strict has been set to 'on'

change the declarations of your constants, option strict on requires variable declarations

Code:
Const iStop As Byte = 0
    Const iStart As Byte = 1
    Const ProcessPriorityClass As Byte = 29

and change your event routine to have the same signature as the evnthandler (as stated by the error):

Code:
Private Function StopProcessProtection(ByVal sender As Object, ByVal e As System.EventArgs) As Boolean
        Try
            StartProcessProtection(iStop)
        Catch ex As Exception
            MessageBox.Show(ex.Message & vbNewLine & ex.InnerException.ToString())
        End Try
    End Function
