Scrolling control under mouse cursor
I'm looking for a way to smoothly scroll the control under the mouse cursor

Surprising threading issue
In my app, I need to connect to an external web service. I need to

to find and colour if it is a duplicate...
I have a very large spreadsheet that I need to compare with another and find
the duplicates between both and delete them.
I would prefer to have the duplicates first highlighted [shaded or coloured]
so I can review them before deletion...
what formula would I use to do this? I'm rather new the excel and know a
little bit more then the basics.
Any help would be appreciated!...

Is that related to a line :

event handle into a managed WaitHandle so I can call one of the WaitHandle's
Wait() methods. How do I do this?
The only way I see is to either:

Understanding Installers
Hello,
I wrote a Windows service in C# (.NET 1.1). As usual, it has its own

DataContractJsonSerializer Serializes item, then cannot deserializ

then fails to deserialize properly from that value. We've simplified it,
bypassing the database, encoding, etc and it still fails, however we are
serializing the exact same types in other areas of the application using the
same shared method and they all work just fine.
