Does anyone know where I can find a Stream splitter implementation? I'm looking to take a Stream, and obtain two separate streams that can be independently read and closed without impacting each other. These streams should each return the same binary data that the original stream would. No need to implement Position or Seek and such...
Using C++ and .net I have a stream of data I want to display as a scrolling image. Each time I get some new data I want to add it as a new row (128x1 pixels) and scroll the previous contents to one side. My first stab at the problem involved rendering the entire data set each time I got a new row. This worked, but was far too slow, so I...

For example is the current item the first or last item in the enumeration: string s = ""; foreach (var person in PeopleListEnumerator) { if (PeopleListEnumerator.IsFirstItem) s += "["; s += person.ToString(); if (!PeopleLis...

I've discovered what may be the perfect answer to a question on buffered drawing, but for some reason my version of VS2008 doesn't seem to have a WriteableBitmap? I've tried including the relevent namespaces as per the documentation: using namespace System::Windows::Media; using namespace System::Windows::Media::Imaging; But that just...

I'm writing a calendar control in .Net WinForms that will show a tooltip for each date. What's the best way to determine when to show the tooltip? Showing it immediately in MouseMove would make it get in the way, so I'd like it to show when the mouse hovers over each date cell. The MouseHover event only fires on the first hover after ...
I read through quite a few similar questions here on SO but none were in quite the same situation as I am. Previously, user enters in a ton of info including SSN, Spouse SSN, and CC data. When the user completed the process, the info was pushed on PDFs, zipped up (which then got encrypted), and then FTPed back into our server. We save...
I'm curious if there are any Java abstractions that are similar to .Net's AppDomain. In particular, I'm curious because I've found that with our Coldfusion/J2EE server we need to restart it every few days due to a slow memory leak that we haven't been able to easily track down yet. This can wreck our long-running processes and we'd rea...

Essentially, does anyone know of a good, and simple, .NET compatible library, that is able to take in, say, a bitmap object or image object, and give me back any text on that image? cheers ...
