    Detect whether or not a network interface or the network itself is up or down? Please let me know. Thanks.
  3. Re: Calling C# function w/out param doesn't work

    I found the problem... actually my example above wasn't entirely accurate.

    "SomeFunction" takes an interface as a parameter, not an object.

    This code works below:


    IMyObject...

    I have a C# function


    SomeFunction(out MyObject obj)

    When I call this function from Managed C++

    Thanks, I tried that already but that doesn't help either. It's such a strange problem because when these preprocessor definitions are not defined everything works perfectly fine. This app has...
  11. Re: Converting project to UNICODE causes crashes

    Allocating memory for an object on one thread and deleting it on another thread? I thought that was ok and that thread share heap space?

  15. How come there isn't a thread safe way to read an int?

    I was investigating using the ::InterlockedXXX family of functions but how come there isn't a thread safe way to read an int? What should be done if I want to read an int safely? Thank you

    Re: Multiple Inheritance Problem

    Thanks, but I thought a pointer was just a variable that held a 4 byte integer memory address. I don't see how casting this back and forth can cause so much problem.

  24. Something about C# events that I don't understand.

    Why does this occur?
    I have a piece of code that looks like the the following:



    void MyEvent()
