Tutorial: How to Change the Charging Battery Icon on a Jailbreak iPhone with Winterboard

noreply@blogger.com (jeff) — Sun, 09 May 2010 05:23:00 +0000

Here's how to make a custom icon to replace the big green battery that displays on the lock screen when your iPhone is charging. This tutorial assumes that you have Jailbreaked your phone and have installed OpenSSH and WinterBoard on your phone (via the Cydia app) and have an SSH client installed on your PC/Mac (such as WinSPC for Windows or Terminal for Mac/Linux).

Step 1 - Create the Theme Directory

Open an SSH connection from your PC to your iPhone and navigate to the root directory

Navigate to Library/Themes. Note that the Themes folder is actually a shortcut, and will take you to the following physical directory: /private/var/stash/Themes.XXXXXX (XXXXXX is a series of letters and numbers that differs on each phone).

Within the /private/var/stash/Themes.XXXXXX folder, create a new folder and name it whatever you want your theme name to be, ending with .theme, for example My Custom Battery.theme

Click into the folder you just created and create a folder named Bundles

Click into the Bundles folder and create a folder named com.apple.springboard

Step 2 - Create Images

The charging battery icon is actually a series of 17 .png files. As the phone charges, the phone displays the proper image.

Find or create a series of 17 images. If they are not already in .png format, save them as such using your favorite image editor such as Photoshop, GIMP (free), or Aviary (free).

The image size of the files should be 264 pixels wide by 129 pixels high. This will ensure that the icon is properly centered and sized on the screen.

The files must be named in series, from BatteryBG_1.png to BatteryBG_17.png

If you do not want a reflection of your icon to show up underneath it on the lock screen, create a fully-black .png file that is 1 pixel wide by 129 pixels high and name it BatteryReflectionMask.png

Step 3 - Move File and Use Your Theme

Using your SSH client, copy all of the .png files into the
/private/var/stash/Themes.XXXXXX/>My Custom Battery.theme/Bundles/com.apple.springboard directory you created in step 1.

Open the WinterBoard app on your iPhone, and go to the Select Themes section. You should see your new theme at the top of the list.

Select the theme and close WinterBoard. This will cause your phone to respring. After it does, your new theme is in use.

Plug your charging cable into your phone and you'll see your new battery indicator.

Client-Side Validation: How to Validate Controls in Each Pane of an AjaxControlToolkit Accordion

noreply@blogger.com (jeff) — Fri, 09 Apr 2010 15:33:00 +0000

I'm using the AjaxControlToolKit Accordion, and I needed to validate the controls in each pane before allowing one to navigate to the other panes. I wanted everything to be client-side, because I don't want any post-backs until the whole form is validated. Since I didn't have any luck finding any good examples, here's one I put together. It uses the RequiredFieldValidator control as well as the ValidatorCalloutExtender. If you don't like the fly-out validation, just remove the ValidatorCalloutExtender controls as well as the Display="Hidden" attribute in the RequiredFieldValidators.

Sorry about the funky formatting. A copy/paste into a new aspx file should work with no modifications. I also have a downloadable self-contained aspx file. Enjoy.

So exactly how much does it cost to hire a Ukrainian hacker to bust into someone's GMail account? Apparently not very much. If you ever feel the need to hire one, make sure you spend enough money to get one who knows how (and has the gumption) to cover his tracks.
