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,...

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...

See this: http://stackoverflow.com/questions/4325714/wont-let-me-delete-rows-in-sql-server-2005-management-studio
Looks like your table somehow doesn't have a primary key.
Using SQL Server...

Or, in case the user is allowed, but not required, to press enter, you can additionally handle the LostFocus event.

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,...

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...

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.

Also, is this a service by any chance? If so, take a look at this.

Hi and welcome to the forums.
When posting code, please use the
tags - they will keep existing code formatting and help others read your code.
Now, about your question - um... what exactly...

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...

So far, this peace of code doesn't really do anything:
Private Sub lstNames_SelectedIndexChanged(sender As Object, e As EventArgs) Handles lstNames.SelectedIndexChanged
Dim query = From...

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...

Here's what I've found on this page.
It seems that you can simply pin an arbitrary element of the array outside of your loop, and the entire array will be pinned - so you don't really need...

Oh, I was switching among several tabs, didn't see you've answered already - and you gave it quite a bit more thought than I did.
Right - I forgot that the user input will still update the...

Superbonzo, awesome post/topic! :D
A few points:
They are transition probabilities, but the "conditional" part is most likely not true - the process where one state collapses into some other...

It seems that the NumericUpDownAcceleration objects within the collection returned by the Accelerations property do not change the number of ValueChanged events per second, but rather determine by...

Yeah, me to, and in general it's a good thing to do because it helps the client developer debug his own code, rather than hide the error that might come back with a revenge. But, there are specific...
January 4th, 2014, 05:57 PM
Yes, but note that if you are range-checking client input, then you have to decide what to do if the input is invalid (throw exception, use default value, ignore, etc.) - so if you look at it from...

You are, of course, correct, but I think the OP is not really looking for an existing solution/framework, and rather wants to learn and understand the inner workings of such architectures.
January 4th, 2014, 03:20 PM
But note that, depending on how you construct your code, even using enums can give you the same error. Enums can be type-casted from integers, and so can end up having values you didn't specify in...

If BusyIndicator is an instance variable or a property, then it's because those two methods, GetDriveAndFile() and CRCChecker(), are static.
If you can change the code of those methods, then either...

Well, we normally can't tell if you have mistakes without knowing what the system is supposed to do and how it's supposed to function in more detail - because there's no one specific design that is...

I think you could use the same approach video games use - they basically let the message loop run as fast as possible, getting (and making) status updates on each iteration. So your program is just...

BTW, to make a copy of a list, you must do it explicitly (or in general, for other data structures, use a method that does it, if one is provided - but make sure to read the docs to know how deep the...

To understand interfaces you first need to have at least some idea of the concept of type abstraction (generalisation), type derivation and specialization, and inheritance in object-oriented...
