The ClipboardViewer registers itself in the Windows Clipboard Chain and displays the current contents. Text (including Unicode and RichText), Pictures and "FileDrop" (displayed as a String of Paths) are supported.
It optionally reregisters itself regularly (somehow sometimes it doesn't get updates anymore...). Also optional is a bring to front / send to back mechanism, so the window stays hidden behind other windows and only presents itself if the clipboard contents changed. You can also make it not show anything by double clicking the status bar; could come in handy when copying passwords while being watched. Note that this isn't really a security feature.
Programmed in C# using Microsoft Visual Studio 2010. Requires .NET Framework 4 (I think).
Current Version: 126.96.36.199 (random rapid number increase ftw)
Download (includes sources)
(to use it you only need the binary ClipboardViewer/bin/Release/ClipboardViewer.exe)
(Screenshots from before 188.8.131.52)
If there are multiple recognized formats present at the same time, they are all displayed (right picture: UnicodeText in the top half and FileDrop in the lower half).
One major enhancement that is planned (but may take a while as it requires some rewriting) is the usage of a BackgroundWorker as it solves unresponsiveness with huge amounts of data and probably improves compatibility with programs that use the clipboard in a strange way.
