All Clipboard Formats


It gives you possibility using all existing clipboard formats in VB. It is designed as ActiveX Control so you can use it in ASPs as well.
Standard implementation of:
- plain text
- rich text format
But also:
- Biff5
- OEM text
- DIF
- UNICODETEXT
- SYLK (The most powerfull)
- CSV

Original Author: Josip Bugarcic

Inputs

any text as the first pameter and clipboard format as the second

Returns

puts text in clipboard in different formats. You can put any text (even two different) in two different formats and decide which one you want to take and where

Side Effects

Probably this will not work for large amount of text altough I didn't find any problems
