Which bit don't you know how to code? Have you got code to read the file in? What format is it in? Are the dates in the file in a meaningful format? Are you reading the data into a meaningful structure in some way?

Perhaps an example would help?

Your perception is incorrect. The described behaviour is default in Windows, and Windows apps should adhere to the standard.

If you tab into it, you are at the beginning.

It is not a problem, it is how it is supposed to work. When activating a control with the mouse, the cursor does not go to the start but where you select. All controls work like that. Making it work differently means unexpected behaviour.

Also, someone doing data-entry does not move to the next control using the mouse, it would make for very inefficient data-entry.

I think you are asking how to move the textbox caret to position 0 when the empty textbox is clicked.

The first part is to get the empty state of the maskedtextbox before any data has been entered. At that point the Text property value is not String.Empty but a representation of the mask. This 'empty' text can be obtained by capturing the Text when the MaskChanged event fires. For your example it is

"(   )        "

The second part is picking a suitable place to move the caret. When an unfocussed textbox is clicked the sequence of Enter, GotFocus and Click events occur. You'll find that attempting to set the caret position in either the Enter or GotFocus events will fail and changes must be made in the Click event handler.

Combining that information gives some prototype code

private String emptyText;

private void MaskedTextBox_MaskChanged(object sender, EventArgs e) {
  // Capture the empty text
  MaskedTextBox mtbx = (MaskedTextBox)sender;
  emptyText = mtbx.Text;
}

private void MaskedTextBox_Click(object sender, EventArgs e) {
  MaskedTextBox mtbx = (MaskedTextBox)sender;
  String currentText = mtbx.Text;
  if (currentText == emptyText) {
    // Move the caret to the start of the line
    mtbx.Select(0, 0);
  }
}

EDIT : Correct operation of this code requires that the MaskChanged event handler is attached before the Mask is set.
Alan.

Hello everyone and specially Jose Menendez Póo, author of the

Quote:
A Professional Calendar/Agenda View That You Will Use

article.

I must say that I'm overwhelmed by its complexity and beauty.
I wonder if any of you, who are familiar with this project, have any kind of written stuff or any kind of notes explaining the project in some details.
Also, the project uses a utility class of the name

Quote:
System.Windows.Forms.Calendar.dll

and I wonder again if the class is ever published, or if any of you have access to it in the non compiled version, So I can study it.

I hope to get an answer here.
Thank you all,
Mark

To add to what Griff said; you can easily decompile any .NET assembly. I'm using ILSpy, but there are more alternatives.

Your calculations are wrong res *= 10 + 3; is the same as res *= 13; But you do not need that switch statement, just replace it with:

res *= 10;
res += element_of_arr - '0';

Re: It must parse string numbers to integer but it's out is zero

OriginalGriff1-Jul-18 21:39

res is integer, which is a value type - so it's default value is zero.
When you do this:

res *= 10 + 1;

You are effectively saying this:

res = res * (10 + 1);

Not

res = (res * 10) + 1;

So if you start with zero, you will always get zero as a result.

But is there a good reason why you don't just use int.TryParse:

Console.WriteLine("Try parse it...");
int result;
if (int.TryParse(input, out result))
    {
    Console.WriteLine(result);
    }
else
    {
    Console.WriteLine(string.Format("\"{0}\" is not a valid integer", input));
    }

from time to time, I see some sample code that is handed to me that has a code snippet that looks like this:
<code>public string Name { get; set; }</code>

Does this actually do anything? Does it really make it so that one can set and get the "Name" string variable?

I have always thought that what is required is something like this:
<code>private string name;

public string Name
{
get
{
return this.name;
}
set
{
this.name = value;
}
}</code>

Am I correct?

Please advise.

Yes, they are Auto-Implemented Properties (C# Programming Guide) | Microsoft Docs. They basically do the same thing as you're used to writing by hand, but with a field that has some compiler-generated name which is not a legal identifier in C# so you cannot accidentally (nor on purpose) refer to the backing field directly.
