Open Source Password Management Software Project Description (attachment code)

First, introduction

Software Name: Open Source Password Management Software Development Language: JavamIDP Version: 1.0 Development Environment: CodeWarrior J2ME WTK1.03 Test Environment: J2ME WTK1.04 Chinese Supplement Pack

Introduction: With the development and progress of society, there are many password information that everyone needs memory. Such as bank card password, mailbox password, forum password, etc. This software implements all kinds of password information for the user's mobile phone, stores and manages users. Main features: 1, increase your password. The new password is stored. In the new password, the user can store the password ID, that is, password use, password, and note information. 2, check the password. View, modify and delete existing passwords. 3, set the password. You can set your password for the software. That is, when using this software in the phone, the user needs to enter the password to enter. It has been provided to delete the password function.

If you have any good suggestions, please contact me, CQUCYF @ 263.net 2, use J2ME WTK to compile and run the source code 1, create a new project in KToolbar: Project Name: Arbitrary (for example, PM) MIDlet class name: PM.Core.PasswordManagerMIDlet2, copy the source code to the Apps in your J2ME WTK installation directory, the path is: Project Name / SRC // PM / C: / J2ME WTK installed in C: / J2mewtk directory The project name is PM, the full path is: C: / J2MewTK / Apps / PM / SRC / PM / Core3, compile and run the project using KToolbar.

Remarks: If you need to display the Chinese name in the simulator, you can change the NAME to "Open Source Password Management Software" under the SETTING / MIDlets in the KTOOLBAR in the case where the item is turned on.
