    using MsgQ in Microsoft

    Hi gurus,
    Almost all my experiance in programming is under linux. I have to devlop a ThreadPool under MS VB2008.....
    Though, i have no clue about msgQ in MS and msdn talks only about MSMQ (What is that???? Something about MsgQs in distributed applications...), and unfortunatly doesent supply the most important thing: API???? What is up with them?

    I begin to think that there isnt any thing like msgQ in MS.....and they wany u to write it yourself (Is that fun or what???!!@#@)

    I would appriciate any help, Thank you all!

    But only shell applications?
    I've never done any windowed application for linux but I guess it's pretty much the same approach as in Windows.

    Yes there is a message queue for every window in a windows application. You don't have to implement it though, MS has already done that for you.

    Debugging is twice as hard as writing the code in the first place.
    Therefore, if you write the code as cleverly as possible, you are, by
    definition, not smart enough to debug it.

    VB ? in that case you are in the wrong place. VB isn't the same as C++ .

    There is one big difference. Windows uses messages and messagequeues to dispatch messages. Linux doesn't know what a message server is, it uses slots and signals to connect callback functions to objects.

    Are we talking about the same stuff here? Is this so even in a GUI application using KDE or similar?

    This is the Visual C++ forum, so you are posting in the wrong forum.

    At any rate, VB2008 is managed code. As such there is already a built-in thread pool class, called ThreadPool.

    If you don't want managed code, then the only alternatives in VB is VB6. If you use VB6, you can call the Win32 thread pool api, QueueUserWorkItem.

    Windows is an event based system and uses messages and queues to communicate with the Windowy applications. Window size, repaint, mouse movements, etc are passed via with windows messages.

    The Windows messaging system is different than MSMQ, which is a Message Queue system used to pass data between computers (or across the internet).

    In terms of coding, both managed code and native code has classes or api's that work with MSMQ.

    There is plenty of documentation on all Windows api's. A good place to start is Msdn.

    If you are talking about something like JMS (Java Messaging System), there certainly is. It's called MSMQ.

    They certainly do not.

    I think so

    The slots and signals was created by QT, and KDE is build on QT.
