C # Infinite column grading program code sharing good Things 1th/3 page _c# Tutorial

The structure of a database table must have the following fields:
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7 this.alt= ' Click here to open new Window\nctrl+mouse Wheel to zoom in/out ';} ' Border=0>
Description of each field:
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7 this.alt= ' Click here to open new Window\nctrl+mouse Wheel to zoom in/out ';} ' Border=0>

C # Unlimited column classification program code sharing [2] core class description

This program is written in C # for scripting, while supporting the Access/sql server database.
This procedure function: column infinite classification, column move, add, sort, delete (column tree), easy to operate, deployment, use simpler, provide a unified interface program.
This procedure only then develops, inevitably has the mistake or the bug, welcome to propose, is not very grateful.
