Make a user control transparent

Refer to
http://www.thescripts.com/forum/thread248836.html
http://www.peterritchie.com/Hamlet/Articles/62.aspx


Step 1:
protected override CreateParams CreateParams
{
get
{
CreateParams cp = base.CreateParams;
cp.ExStyle |= 0x00000020;
return cp;
}
}

Step 2:

Add the following lines in the constructor.

SetStyle(ControlStyles.Opaque, true);
UpdateStyles();

Step 3:

protected override void OnPaint(PaintEventArgs e)
{
// TODO: Add TransparentControl.OnPaint implementation
base.OnPaint (e);
}

Example

namespace Magnifier.NET
{

public class TransparentControl : System.Windows.Forms.UserControl
{
private System.ComponentModel.Container components = null;

public TransparentControl()
{
SetStyle(ControlStyles.Opaque, true);
UpdateStyles();
// This call is required by the Windows.Forms Form Designer.
InitializeComponent();

// TODO: Add any initialization after the InitializeComponent call

}

protected override CreateParams CreateParams
{
get
{
const int WS_EX_TRANSPARENT = 0x20;
CreateParams cp = base.CreateParams;
cp.ExStyle |= WS_EX_TRANSPARENT;
return cp;
}
}

protected override void OnPaint(PaintEventArgs e)
{
// TODO: Add TransparentControl.OnPaint implementation
base.OnPaint (e);
}
}
}

TrueMobile 1300 running on Ubuntu with WPA

Refer to: http://ubuntuforums.org/archive/index.php/t-411299.html

sudo wpa_passphrase (your wireless ssid)
The Terminal will say it is getting it or something like that, and there will be a cursor below that line.
Enter your WPA password

Now Terminal will give you a very long string for your key. I just copied and pasted it into NetworkManager's password prompt, and also in the keychain request that came up right after.

sock = timeout(@open_timeout) { TCPSocket.open(@address, @port) }
@socket = Net::InternetMessageIO.new(sock)
@socket.read_timeout = 60 #@read_timeout
#@socket.debug_output = STDERR #@debug_output

check_response(critical { recv_response() })
do_helo(helodomain)

if starttls
raise 'openssl library not installed' unless defined?(OpenSSL)
ssl = OpenSSL::SSL::SSLSocket.new(sock)
ssl.sync_close = true
ssl.connect
@socket = Net::InternetMessageIO.new(ssl)
@socket.read_timeout = 60 #@read_timeout
#@socket.debug_output = STDERR #@debug_output
do_helo(helodomain)
end

authenticate user, secret, authtype if user
