Data Security Wizard is an easy to use data security program, which is able to encrypt your personal files and sensitive data quickly, easily and securely. In addition to encryption, Data Security Wizard still is a reliable and ultra-fast shredders that will help you securely wipe any file, folder, partition and hard disk without any chances for its recovery.Data Security Wizard is designed for the Windows platforms; the application seamlessly integrates into Windows Explorer and can be accessed simply by right clicking on any file, folder or partition and selecting the menu option of function.General encrypt software just can encrypt file/folder by adding limit or hiding. All these are not essential meaning for encrypting data, the nonlicet user can access the encrypted data by some simple ways, such as "Modify Registry", "Data recovery software" etc. so your important data have no security under this situation. But, if you use our product - Data Security Wizard, the puzzle will be solved completely. Our software supplies a suite of project for protecting your important data.Key Features:The powerful arithmetic for encryption: Data Security Wizard use powerful encryption arithmetic. Traditional encryption arithmetic is not safe. Data Security Wizard has improved these defects.Safely wipe your data: Data Security Wizard will use particular arithmetic to wipe file/folder, which has different file system. The process will be quicker, safer and never damage other data.Easy for use: You can use right-clicking menu to finish the operation that you want.User-defined password: You can encrypt file/folder with not only account but also user-defined password.

Introduction:

A transparent(on-the-fly) disk/cd encryption system, which combin with AES 256-bit encryption. DiskEncryptor can make a disk partition encrypted on the windows system. After encypted, all the operation for this encrypted disk is the same as a normal disk, when read and write, the decryption and encryption is running at background and transparently.

Architecture:

Using the existing technologies of kernel mode, working as operation system kernel mode, when the encryption disk is accessed, encrypt and decrypt are utomatically.

Functions:

Almost support all kind of Removable, Fixed storage drive, Memory Card and floppy disk.
Support for encrypt cd/dvd image(.iso) for mount to virtual cdrom or burn to cd/dvd.
Using 256 bit AES arithmetic, support high security level.
Encrypt disk partition directly, after encrypted, if someone take it, but he/she have no password or not install this software, the partition can't be accessed by any case.
When insert a encrypted disk, a dialog will show automatically to tell you input your password of the disk, see figure 1.
Even if lots of data in the disk enctypted, this data will exist all the same after enctyption.
Run as a windows service, DiskEncryptor can working on a normal user account.
Support for the newest windows system------VISTA.
Support for AMD64 and intel EM64T computer.
Features:

Easy to use, use the encrypted disk partition as easy as his/her normal disks.
By with the 256 bit AES,support high security level data protection.
Support all Windows File System
Support storage capacity as max as your windows system.
Even if the password you input was incorrect, the data will not be destroyed.

CalculPro will help your elementary school students practice mental arithmetic or to do fractions. Choose addition, subtraction, multiplication, division or fractions; then set the range of numbers and the number of calculations for an exercise. The program shows you two numbers or fractions respectively, and you enter an answer. Right or wrong answers get audio feedback and there's a pie chart to show your percentage of correct responses. For a greater challenge, play against a friend or set a time limit for a correct answer. The performance of the students is stored in a data base. This allows a results table to be produced. It can be printed or exported as a text file. CalculPro is able to run on networks. This allows you for instance do a test with your students, using a local network and a common database. You may then evaluate the performance of your class automatically. Import of exercise data from one CalculPro - database into another is supported. The interface and sounds are available in English or German. More languages are supported.

Abacus Calculated Fields for ACT! 2005 and ACT!2006 by Sage now brings you the ability to calculate fields, copy fields, manipulate data and produce results dependent on data within other fields all within a simple, easy-to-use interface.

Abacus Calculated Fields for ACT! 2005 and ACT!2006 was designed with ease of use as its main aim.

- Writing a formula is simple.
- Assigning the formula to a field is simple.
- Reviewing and changing your formulas is simple.

Make any field "calculated" in 2 steps: just select a field on layout (using the context menu) and write a calculation formula.

"Calculated" fields will always be up-to-date since calculations will be run automatically every time when you change the value of any field that is a part of the formula.

The "Abacus Calculated Fields" add-on really makes light work of what has been the missing link in ACT! for years.

Abacus integrates smoothly into the ACT menu system and the calculations just work. Isn't that what you want from a field calculator?

If you need complex conditional calculations, Abacus can do that too - just use IF...THEN...ELSE and CASE conditional statements to build calculation scenarios. In fact, Abacus can handle extremely complex calculations simply.

There are over 80 functions supported by the Abacus add-on (mathematical, string, date/time, financial functions: mortgage/loan calculation, standard arithmetic operators along with boolean functions and data type conversion functions). Abacus can handle any calculation with ease.

The Abacus add-on can be used on Contact fields, Group fields or Company fields and you can run your calculations either automatically or manually.

When it comes to calculations, Abacus Calculated Fields for ACT! is the first choice.

Easy Date Converter is a program to perform arithmetical operations with Common Era (Gregorian) and Julian dates, Julian day numbers and ordinal dates of the form yyyy-ddd. It is a bilingual English/German program.

Suppose you run an advertisement which expires 45 days from today. What date will that be? How many weekdays are there in 2006? If you have an investment which matures on June 30th, 2007, how many days away is that? When will be (or was) the 10,000th day in your life? How many years, months and days until December 21st, 2012? If you find this sort of calculation a tad difficult then this program will make it easy.

Easy Date Converter provides four calendrical operations:

1. Calculation of the number of days from one date to another.
2. Addition of a number of days to a date and subtraction of a number of days from a date.
3. Interconversion among Gregorian (a.k.a. Common Era) dates, Julian Calendar dates, ordinal dates in the form yyyy-ddd and Julian day numbers.
4. Display of a month in any year according to either the Common Era Calendar or the Julian Calendar.

Weekend days may be included or excluded in date calculations.

The program supports batch computation using predefined operations in an input file.
