        GET_CONTEXT = (&H8)
        SET_CONTEXT = (&H10)
        SET_INFORMATION = (&H20)
        QUERY_INFORMATION = (&H40)
        SET_THREAD_TOKEN = (&H80)
        IMPERSONATE = (&H100)
        DIRECT_IMPERSONATION = (&H200)
    End Enum

    Public Declare Function OpenThread Lib "kernel32.dll" (ByVal dwDesiredAccess As ThreadAccess, ByVal bInheritHandle As Boolean, ByVal dwThreadId As UInteger) As IntPtr
    Public Declare Function SuspendThread Lib "kernel32.dll" (ByVal hThread As IntPtr) As UInteger
    Public Declare Function ResumeThread Lib "kernel32.dll" (ByVal hThread As IntPtr) As UInteger
    Public Declare Function CloseHandle Lib "kernel32.dll" (ByVal hHandle As IntPtr) As Boolean

Form1.vb

Code:

Public Class Form1

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

    End Sub
    Private Sub SuspendProcess(ByVal process As System.Diagnostics.Process)
        For Each t As ProcessThread In process.Threads
            Dim th As IntPtr
            th = OpenThread(ThreadAccess.SUSPEND_RESUME, False, t.Id)
            If th <> IntPtr.Zero Then
                SuspendThread(th)
                CloseHandle(th)
            End If
        Next
    End Sub

    Private Sub ResumeProcess(ByVal process As System.Diagnostics.Process)
        For Each t As ProcessThread In process.Threads
            Dim th As IntPtr
            th = OpenThread(ThreadAccess.SUSPEND_RESUME, False, t.Id)
            If th <> IntPtr.Zero Then
                ResumeThread(th)
                CloseHandle(th)
            End If
        Next
    End Sub

    Dim ExeName As String = IO.Path.GetFileNameWithoutExtension(Application.ExecutablePath)

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim game As Process() = Process.GetProcessesByName(TextBox1.Text)
            SuspendProcess(game(0))
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim game As Process() = Process.GetProcessesByName(TextBox1.Text)
        ResumeProcess(game(0))
    End Sub
End Class

Ich bedanke mich schon im vorraus f�r eure Hilfe.
