VISUAL BASIC_SAVE& OPEN

HI ! ! ! ! ! ! ! ! ! ! ! ! Everyone ! ! ! ! ! ! !
I have inserted a textbox in my userform and two buttons captioned as "SAVE" and "OPEN".
Now, i want to ake the following changes-
1. When a viewer types into this box and clicks on "SAVE", a windows-like box should appear where he can save the text wherever he wants.
2. When the user opens the project and clicks on "OPEN", then a windows-like box should appear, where he can open any saved file.
3.Also, is there a method for method as "NEW"?
Please reply at yur earliest convinence..........................
