Minimize other applications?

[Ultimasnake]

Hi i am working on something new (i hope :P) but i need to get all system processes allong with the ability to hide a certain processes windows (so not the app itself)

can anyone provide me with C# code? i managed this in Vb.net a long time ago (the process part) but cant seem to find it anymore nor remember it and i cant seem to do it in C# :S

here's a quick example i knocked up just for you mate ...

        [StructLayout(LayoutKind.Sequential)]
            private struct WINDOWPLACEMENT
        {
            internal int Length;
            internal int flags;
            internal int showCmd;
            internal Point ptMinPosition;
            internal Point ptMaxPosition;
            internal Rectangle rcNormalPosition;
        }

        [DllImport("user32.dll")]
        private static extern int GetWindowPlacement (int hwnd, ref WINDOWPLACEMENT lpwndpl);
        [DllImport("user32.dll")]
        private static extern int SetWindowPlacement (int hwnd, ref WINDOWPLACEMENT lpwndpl);
        private const int SW_MINIMIZE = 6;

        private WINDOWPLACEMENT oldWinPlace;
        private WINDOWPLACEMENT newWinPlace;

        private void button1_Click(object sender, System.EventArgs e)
        {
            Process[] procs = Process.GetProcesses();
            foreach(Process p in procs)
            {
                ListViewItem lvi = new ListViewItem(p.ProcessName);
                lvi.SubItems.Add(p.MainWindowHandle.ToString());
                listView1.Items.Add(lvi);
            }
        }

        private void listView1_Click(object sender, System.EventArgs e)
        {
            if(listView1.SelectedItems.Count != 0)
            {
                if(Convert.ToInt32(listView1.SelectedItems[0].SubItems[1].Text) != 0)
                {
                    int hHandle = Convert.ToInt32(listView1.SelectedItems[0].SubItems[1].Text);
                    oldWinPlace = new WINDOWPLACEMENT(); // this will hold the window's existing Placement info  ( For restoring the window later ).
                    newWinPlace = new WINDOWPLACEMENT();
                    GetWindowPlacement(hHandle , ref oldWinPlace);
                    newWinPlace.showCmd = SW_MINIMIZE;
                    newWinPlace.Length = Marshal.SizeOf(newWinPlace);
                    SetWindowPlacement(hHandle , ref newWinPlace);
                }
            }
        }

        private void button2_Click(object sender, System.EventArgs e)
        {
// to restore the window to it's original state...
            try
            {
                if(listView1.SelectedItems.Count != 0)
                {
                    if(Convert.ToInt32(listView1.SelectedItems[0].SubItems[1].Text) != 0)
                    {
                        int hHandle = Convert.ToInt32(listView1.SelectedItems[0].SubItems[1].Text);
                        SetWindowPlacement(hHandle , ref oldWinPlace);
                    }
                }
            }
            catch(Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }
