Clipboard API calls??

Ok...I'm currently using Clipboard.SetText/GetText to write a clipboard monitor program. My problem is that it doesn't work 100% of the time, mainly when I copy something out of a Microsoft program (go figure!), then try to restore a previous clipboard entry. Other than that it works. Example:

-Copy "whatever" from some program, it gets stored in the list of
clipboard entries in my prog
-Copy "ASDF" while in MS Word, gets put in the list
-Click on "whatever" in my program and hit the "Copy" button, it does Clipboard.settext "whatever"
-Hit CTRL-V in form on some webpage and "ASDF" gets pasted

What's the deal?? Are there Clipboard API functions that I can use that will fix this? If so, I would only need something similar to Clipboard.GetText and Clipboard.SetText. Thanks for any replies.

there are api functions, but you need to allocate global memory, and pass a pointer to it. it's messy to do with VB.

For standard Cut, Copy and Paste, send the WM_CUT, WM_COPY and WM_PASTE messages
