Environment: VC6 SP4, NT4 SP6, 2000 SP1 Probably everybody who reads this article is familiar with msdev.exe. We know that if we type “msdev /?”, we get usage information on the console. However, if we type “msdev”, the IDE comes up. This dual behavior is achieved through an additional executable, called msdev.com. In this article […]

Bruce Eckel’s Thinking in Java Contents | Prev | Next When writing code with exceptions, it’s particularly important that you always ask, “If an exception occurs, will this be properly cleaned up?” Most of the time you’re fairly safe, but in constructors there’s a problem. The constructor puts the object into a safe starting state, […]

Early networks were satisfied to provide unique names for machines […]

Bruce Eckel’s Thinking in Java Contents | Prev | Next Historically, network programming has been error-prone, difficult, and complex. The programmer had to know many details about the network and sometimes even the hardware. You usually needed to understand the various “layers” of the networking protocol, and there were a lot of different functions in […]

If you take that approach, you can make only one of those threads in your program. This limits your flexibility if you decide […]
