I don't think reading a book prior to an interview necessarily dictates that he has no knowledge of what he's doing - he didn't say that, it's a fair question. I've yet to have an interview I can't handle technically, but I still read stuff prior to going.
And even if the question is misguided, a whole group of people saying give up, get a career change etc. IMO is unhelpful as well as condescending.
Also, the book recommendation is valid to anyone reading the thread who might not be trying to wing an interview. These are excellent books.

Only one person suggested giving up and getting a career change. Everyone else suggested that experience would be a better choice.

You're doomed ... if you need to ask others for "book recommendations" at this stage of the game.
You should have created your own list of reference materials by now.
The fact you don't indicates a lack of initiative and commitment (IMO). Find another career.

I have already checked other questions here but the answers are not related to my issue. the following code allows textbox1 to only accept numbers if the physical keyboard (laptop) is pressed:
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
char ch = e.KeyChar;
if ( !char.IsDigit(ch))
{
e.Handled = true;
}
}
but this is not what I wanted (I dont use physical laptop keyboard).
I have windows form with buttons and a textbox1. I designed keyboard and it works well but I want textbox1 to only accept numbers and the ".".
There are only two lines of code inside each button (and only code in the project) which is:
private void buttonName_Click(object sender, EventArgs e)
{
// each button only has this code.
textBox1.Focus();
SendKeys.Send(buttonName.Text);
}
I know how to set textbox to accept numbers if the physical (laptop ) keys are pressed but here in this case I have windows form with control buttons ( each button to print its text into textbox1) and I want to set textBox1 to only accept numbers and the ".". Please help in how to achieve this. Thank you

Use the .TextChanged event as another avenue for filtering / altering text box input.
|
|
|
|
|
You can use TextChanged event as Gerry said.
Then you can verify the text using this method.
public static bool IsNumber(string s)
{
var r = new Regex(@"^-?[0-9]\d*(\.\d+)?$");
return r.Match(s).Success;
}
BTW it also accept negative numbers

Assuming this is Windows Forms, and there's no physical keyboard:
private void NumberButtons_Click(object sender, EventArgs e)
{
textBox1.AppendText((sender as Button).Text);
}The assumption here is that you have a set of Buttons whose Text values are from #1~9 and #0, and they all use the same Click EventHandler.
Of course, we don't know here exactly what you mean by "numbers:" are you allowing decimal-point, commas, negative numbers, culture-specific numeric encoding, etc. ?
Will also have a back-space button ? If you wish the user to have some way to move the insertion point around in the TextBox, that'll take a bit more work (using virtual arrow-key buttons ?).

Using the code below, I am trying to find the text
<add key="GetListDefaultResultSize" value="6500" />
but when I view what my program is seeing, it is actually seeing
<add key=\"GetListDefaultResultSize\" value=\"6500\" />
How do I adjust for the escape characters that are added before the quotes when my code does a File.ReadAllText?
string allFileText = File.ReadAllText(networkFilePath);
if (allFileText.Contains(replacementLine))
{
lvwAppendFiles.Items.Add(networkFilePath + " contains " + replacementLine);
}
else
{
lvwAppendFiles.Items.Add(networkFilePath + " does NOT contain " + replacementLine);
}

Since it looks like XML, I would consider using the
System.Xml and System.Xml.Linq classes instead of trying to interpret the input myself.

If you are looking at the string in the debugger, it is the debugger that is adding the escape characters to what it is displaying, they aren't actually in the string.
The easy way to verify this is to check the Length of the string. It should not include the escape characters in the count.

Hello everyone.
I'm currently trying to get into htmls and as a start wanted to create a program which reads the current Artist and song out of a Webradio.
So far i can read out an Artist and song but it's not the current one but the last one in the list on the site...could anyone help me getting the current one? That'd be great. 
Here is my Code so far:
using (WebClient client = new WebClient())
{
string htmlCode = client.DownloadString("http://www.planetradio.de/music/trackfinder.html");
var parser = new HtmlParser();
var document = parser.Parse(htmlCode);
var hitfinderTable = document.All.Where(m => m.Id == "hitfindertable").First() as AngleSharp.Dom.Html.IHtmlTableElement;
foreach (var row in hitfinderTable.Rows)
{
var artistName = row.Cells[2].TextContent;
var songName = row.Cells[3].TextContent;
label.Content = artistName + " " + songName;
}
}
Thanks to everyone in advance.

I don't see anywhere where you are "sorting"; you're just lazy-loading "a list" and asking for the first entry (regardless of order).
You're also not "appending" to "label.Content" ... if that's what's on your mind.

Need Convert character to ascii value. For character "‚" ascii value is 130 but I got 8218.
string is "õí‚è‹".
for (int i = 0; i < rtfSource.Text.Length; i++)
{
rtfSource.Select(i, 1);
strTemp = rtfSource.SelectedText.ToString();
strChar = strTemp.Substring(0, 1);
iCode = (int)strChar[0];
}

What you have is not an ASCII coded character, and it is not a "comma;" it is Unicode, specifically the single low-9 quotation mark: [^].
So, if you must work with Unicode character sets, you should plan to forget about using plain-old ASCII. There are over 100k Unicode characters, and only 128 in ASCII. While you can access an ASCII "mapping" via the Encoding Class:
byte[] unicode = Encoding.Unicode.GetBytes("õí‚è‹");
string Ascii = Encoding.ASCII.GetString(unicode);The result of this would be: "?\0?\0 ?\09" : the "?" indicates result is unknown for a given character.

its not comma, and ttf font not Unicode font. Alt+0130 is it value. How can I get the ascii value 130. third character in the string.

Alt+130 would be é not è (which you wrote in your question). è would be Alt+138.
But those are both not ASCII since ASCII has only 128 Symbols.
So what exactly do you want to do?
Convert the third character (which would be ",") or the è ?

I want to mapping characters by based on ASCII Value.

Then you need to convert the Unicode characters in your data to their ASCII equivalents first. But be aware that you may lose some of them completely if they do not map to an ASCII character.

Unicode isn't a font - it's a character set which can be displayed on a suitable context using a font to "describe" the exact shape to be drawn for each character. ASCII is a different (and much smaller, more limited) character set - which can also be displayed using a font, but the number of different shapes that can be drawn is far fewer.
Fonts are things like Arial, Times New Roman, Verdana, Wingdings - they are ways to display the same character from a character set differently.
And the third character in the string "õí‚è‹" is ','. The character at index 3 is 'è' which exists in the Extended ASCII character set (which has 256 characters) but doesn't exist in the standard 128 character ASCII set.

Which is correct, it's a Unicode character.

I would start by asking the place you got the script from, rather than here.
If it was an article here, then there is a message area at the bottom of the article which allows you to talk direct to the author.
If it was a different site altogether, then I'd start looking there...

I'm wonder if we could write a html helper to render all action method on view as link
i was writing a code something like this but no clues how to complete
public static string UrlBundle(this HtmlHelper helper)
{
Assembly asm = Assembly.GetExecutingAssembly();
IEnumerable<MethodInfo> infos = asm.GetTypes()
.Where(type => typeof(Controller).IsAssignableFrom(type))
.SelectMany(type => type.GetMethods())
.Where(method => method.IsPublic && !method.IsDefined(typeof(NonActionAttribute)));
}
if above method completed should have seen all link as javascript variable
<script type="text/javascript">
var url = {
home: { index: "home/index", anotherAction: "home/anotherAction" },
page: { index: "page/index", anotherPageAction: "page/anotherPageAction" }
}
</script>

Hi guys,
I want to sort in real time (by datetime) information coming from several threads.
There is a thread the constantly polls for latest items. The polling thread appends whatever I return to his existing list of items. I need to returns items in such a way that polling thread's list is sorted at all times.
Here are my requirements:
1. I have several threads, each reading a different event log.
2. Each thread reads all items (events) from this log, and pushes them in a list (specific to that thread)
3. There is a client asking periodically for the "latest" events (sorted by datetime).
Once I put an item into this latest events list, it will disappear from my internal list.
4. The client appends this list to his existing items, and the new resulting list has to be sorted (the client starts with an empty list).
My current algorithm is:
Each time the client asks for "latest" events:
a. Look at all thread's lists
b. If there is one or more threads that doesn't have at least one element, return an empty list
c. Look through all lists, and take the "earliest" element.
d. If the list contains the "earliest" element, contains at least one more element, add this to the "latest" events and go back to step a.
e. Otherwise, return existing list
My take and current tests say that the algorithm is correct.
Can you find a counterexample?
Is my algorithm wrong?
Best,
John
