A Gathering of Small Number Systems Conversions and Operations for WP7

* UPDATE: I have found many bugs and issues with this original code of this library. For an expanded (and working version) you can look at WP7NC.

I know its not too much but I gathered about 16 number-conversion operations and few logical operators in a small DLL for Windows Phone devs who might need it. The functions are:

Converts a decimal number into a binary number in the form of string  (ex: 10 becomes “1010”)

Converts a decimal number into a binary number in the form of an array of ones and zeros.

Converts a binary number in the form of a string into a decimal number.

Converts a binary array into a decimal number.

Converts a hexadecimal number int he form of a string into a decimal number.

Converts decimal number into a hexadecimal number in the form of string.

Converts a hexadecimal number in the form of a string into a binary number, also in the form of string.

Converts a binary number in the form of a string into a hexadecimal number, also in the form of string.

Perform bitwise AND operation between two binary numbers in the form of a string.

Perform bitwise and between two hexadecimal numbers in the form of a string.

Perform bitwise OR operation between two binary numbers in the form of a string.

Perform bitwise OR operation between two hexadecimal numbers in the form of a string.

Perform bitwise XOR operation between two binary numbers in the form of a string.

Perform bitwise XOR operation between two hexadecimal numbers in the form of a string.

Perform bitwise NOT operation to a binary number in the form of a string.

Perform bitwise NOT operation to a hexadecimal number in the form of a string.

* UPDATE 02-12-2012: I have found out many minor mistakes in some of the conversion function. Thus, I have removed the file and re-written the library as an open-source project. More details can be found here.

If you have a suggestion to expand this library, please write it down in the comments or tweet it to me, and I’ll try to include it.

App: Hijri

Hijri

 Hijri for Windows Phone and Hijri Converter for Windows 8


* If you like Hijri for Windows phone, you might also like Saudi Calendar app (التقويم السعودي).

Hijri is a simple application that performs conversion between Hijri and Gregorian dates. It provides a simple interface to convert Hijri-to-Gregorian and Gregorian-to-Hijri dates.

Hijri (for Windows Phone):

In v1.1 a nice feature was added to the converter. This feature is a live tile that shows you today’s date in Hijri, and updates automatically.

The v1.0 of this application used the online service provided by IslamicFinder.org because of the high accuracy of the conversion on this site. Anyway, starting from v1.1, I have moved the service to my own private server so that the conversion is much faster now.

Starting from version 2.0, the conversion is being done using the open API conversion service provided by www.HijriCal.org. The conversion methods used by the HijriCal.org API are:

1. Um-Alqura Calendar (the official calendar of Saudi Arabia). This calendar provides conversion for Hijri dates from 1350 to 1500 hijri. The dates before or after that are converted using option 2.

2. The Hijri calculation method used by Center of Oriental Studies in Zurich University.

If you spot any bugs, please send me reports. Also if you have any suggestions for features to include in the next version, please feel free to contact me on   info (at) mohammedalani.com

Important Notes Regarding the live tile:

1. If you want to turn off the periodic automatic updating of the live tile, please do it from inside the applications. Do not turn the task off from the phone “Settings” menu as it would cause a conflict with the application settings.

2. If you turn off the auto-update of live tile, the live tile will be updated when you start the application.

3. In case you don’t see the date on the live tile, just wait for a few seconds, the tile will flip and show you the date on the back.

4. If you do not open the application for 14 days, the live tile will stop being updated. This is WP7 restriction, for all periodic tasks.
