Windows physical disk image writer in C

My recent project is to write a raw image file into CFast card, and I was looking for a physical disk writer on google. Finally I found this http://m0n0.ch/wall/physdiskwrite.php, but it doesn’t work properly.

GUI is not Englisht
When image size is too big, it doesn’t show the correct size.

Then I decide to make my own physical disk image writer in C.

Be extremely careful to use this tool, incorrect disk number can completely corrupt your disk data! I am not responsible for this.

C# UserControl IPTextBox

I am looking for a TextBox control, which can validate and filter out IP Address. After a bit research, I come with this https://social.msdn.microsoft.com/Forums/vstudio/en-US/4c2aefae-ca6a-4e71-8564-fe73da7107f1/maskedtextbox-formatting-for-an-ip-address?forum=csharpgeneral. It’s easy to implement and simple to use. Just like normal TextBox.

iptextbox

using System.Windows.Forms;
class IPTextBox : TextBox
{
    public IPTextBox() : base()
    {
        SetStyle(ControlStyles.ResizeRedraw, true);
    }

    protected override CreateParams CreateParams
    {
        get
        {
            var cp = base.CreateParams;
            cp.ClassName = "SysIPAddress32";
            return cp;
        }
    }
}

Re-config Brother HL-2130 sharing after Lenovo EZ firmware update

Follow last post Share Brother HL-2130 through Lenovo Iomega EZ Media & Backup Center USB port.

Recently I update Lenovo EZ firmware, but unfortunately Brother HL-2130 sharing stops working.

After some research, I found that CUPS web page is not configured for external IP address.

By default you are only able to access CUPS admin web interface from localhost by going to https://localhost:631.
But to access this page from another remote machine, you need to first make some edits to the cups conf file. So do the following:

1. Edit the cups configuration file located in /etc/cups/cupsd.conf and make the section that looks like:

    # Only listen for connections from the local machine.
    Listen localhost:631
    Listen /var/run/cups/cups.sock

look like this:

    # Listen on all interfaces
    Port 631
    Listen /var/run/cups/cups.sock

2. Then you need to modify the Apache specific directives to allow connections from everywhere as well. Replace the followin section:

    <Location />
    # Restrict access to the server...
    Order allow,deny
    </Location>
    <Location /admin>
    # Restrict access to the admin pages...
    Order allow,deny
    < /Location>
    <Location /admin/conf>
    AuthType Default
    Require user @SYSTEM
    # Restrict access to the configuration files...
    Order allow,deny
    </Location>

to:

    <Location />
    # Restrict access to the server...
    Order allow,deny
    Allow all
    </Location>
    <Location /admin>
    # Restrict access to the admin pages...
    Order allow,deny
    Allow all
    </Location>
    <Location /admin/conf>
    AuthType Default
    Require user @SYSTEM
    # Restrict access to the configuration files...
    Order allow,deny
    Allow all
    </Location>

3. Restart your cups daemon:

    # /etc/init.d/cupsd restart

4. You should now be able to log into cups on your server with:

https://yourserverip:631

How to get 1080p in Youtube’s HTML5 player in Firefox

Recently, I updated my Firefox browser, and when I was watching Youtube, I couldn’t get 1080p HD anymore. 🙁

I found this article and it solved my issue. Let me remember these steps just in case in future it happened again.

Enter
```
 about:config
```
in your address bar to get to the advanced configuration page. Click “I’ll be careful, I promise” (and actually be careful because you can break all sorts of things in there if you’re not!) to continue.
Search
```
"mediasource"
```
to see the options you need.
Double-click both “media.mediasource.enabled” and “media.mediasource.webm.enabled” in order to change their value to “true”.
