I have a case where a VB.Net winforms app needs to play WMV files from across the network. The user running the app cannot be given direct access to the network share.

Many of the API calls I'll need are housed within the User32 library. I can of course use P/Invoke and create a static class to handle this for me. Ho...

Sometimes it's difficult to describe some of the things that "us programmers" may think are simple to non-programmers and management types. So... How would you describe the difference between Managed Code (or Java Byte Code) and Unmanaged/Native Code to a Non-Programmer? ...
I have a incoming stream of bytes (unsigned char) from either a file or network. I need this data placed in a class, and is looking for a NET-way of doing this. I bet some does this all the time, so I guess there is a better method to do this than using BitConverter. I realize I supplied too litle information. Let me try with an exam...

I have an unmanaged C++ library. I would like to expose the functionality for .NET applications. There's one partucular function I am not sure how to handle: typedef void (free_fn*) (void*); void put (void *data, free_fn deallocation_function); The idea is that you pass dynamically allocated buffer to the function and supply a dealloca...
