  1. Re: No "real" random numbers when using loop

    You've made (possibly) two mistakes. First, move all instantiations of the Random class (the lines that have new Random(0)) outside of the loop. It's enough to create the object once - and you don't...
  2. Re: difficult problem of finding a specific numerical minimum in fuzzy series

    Could you just clarify a few more points:

    Is the assumption that after the highest maximum that marks the transition to meaningful data (132.2 in your case), all the following maxima will be...
  3. Re: difficult problem of finding a specific numerical minimum in fuzzy series

    Are you thinking of the data as if sampled from a curve with a bunch of local maxima and minima? Or is it more along the lines of what tiliavirga said?
    What assumptions are you making about the...

    Re: Abstraction concept problem?

    BTW, the reason this distinction is of certain practical importance, instead of being purely philosophical, is, for example, that you can, legitimately, use pointers (the language feature) to...

    Re: Abstraction concept problem?

    I don't think that's the case, though! It's quite a semantics game we're playing here. :D

    I was under the impression that PredicateNormative and others who were insisting on the distinction...
  6. Re: Recursive function: take a non-negative integer and print each digit of that inte


    I have a feeling that your assignment says that you should print it from "left to right" - check that (that's sort of where the recursion comes in - instead of just doing it in a loop).
  7. Re: Is Template Method design pattern and Hook the same thing by different names?

    In addition to the above: the Template method pattern is more about defining a concrete sequence of steps for an operation/algorithm, but with the details of each step abstracted away, so that...
  8. Re: Understanding the Composite Design Pattern

    Yeah - the whole point of the Composite pattern is to have an object composed out of smaller parts, but have the client code treat it the same way as any individual part (by letting the concrete...

    Re: Abstraction concept problem?

    Seems like you guys are talking about two different things here, while calling it the same name.

    Value vs reference semantics is one thing - a concept that is related to the character, and the...

    Re: SQL Begginer

    Sometimes, you just need to know what to look for ("northwind" in this case). Here, check these out:

    Re: Abstraction concept problem?

    Pointers points aside (heh! :) ), a few more things about the design question (downcasting in client code):
    While type-casting from abstractions to concrete types in client code is not necessarily...
  12. Re: Newbie in C sharp/ Microsoft Visio

    Also, after you add assembly & namespace references as described above, check you code for typos and syntax errors (there are both in the code you posted above):

  13. Re: How to return the integer value of a string?

    May I suggest to consider the text of the exercise once again and think about what it's trying to teach you - because I think that the way you are going about it is overly complicated.
    To me, it...

    Re: Random number/array/histogram

    You seem confused about what your histogram should display. The number of calls to roll() has nothing to do with how many different numbers roll() can return. Those two things are independent. Say,...

    Re: .xml to .txt

    No, what he meant was: if you were to write some code that would insert the line breaks and save the output to a txt file, that code would have to parse the original xml file to achieve this - but...

    Or, in case the user is allowed, but not required, to press enter, you can additionally handle the LostFocus event.
  18. Re: Building a parser using two differnt classes

    P.S. For validation, you would check things like if the split results in the expected number of components, and you would catch any exceptions thrown by int.Parse(), etc. If you detect any problems,...
  19. Re: Building a parser using two differnt classes

    That shouldn't be too hard to make. You would use some of the methods provided by the string class. Note that none of these methods alter the original string (string type is immutable) - they all...
  20. Re: Problem : Unable to connect to specified host From C# application

    Yes, but, what are the details of the exception - stack trace, inner exception and all - there's probably a clue in there as to what is going on.

  23. Re: Obj.Orient. Structure question newbie/intermediate

    In addition to what Arjay said, let me just add a few thoughts. Your "manager" classes can do more than just store a list of things - as long as it conceptually makes sense, and as long as the...

    Re: What should I be doing differently?

    Re: Concatenate images - H E L P

    Well, the main thing is to figure out how you'll arrange those images, both within a row, and the rows themselves. What you would do is collect all the rectangles in some list-like container...
