Extended RichTextBox Control

hi. I really needed a Richtext box with Word like functionality.. i mean Bold,Italic etc etc Function. So i decided to write a Custom Control for this Purpose.

Extended RichTextBox Contains Following Controls

1. Rich Text Box [ rtxtBox ]
2. A tool Strip with Basic button including word Formatting Functionality.. [ tsStrip ]
3. A font Dialog [ fntD ], Color Dialog [ clrD ], OpenFileDialog [ ofD ]
here is a pic.

1. First Add a RichText box and a tool strip as show in figure to your Custom Control.
2. Add basic buttons to tool strip according to screen shot (You can add your own image to buttons)
3. And here is the coding..
