Accessing variables in other Windows Form class C#

it should still fix some issue You can do one of two things. Either add a date to the constructor of frmEvent, or add a property to frmEvent and set it before calling .Show().
Constructor way:
code :
public partial class frmEvent : Form
{
  private int SelectedDate;
  public frmEvent(int selectedDate)
  {
    InitializeComponent();
    SelectedDate = selectedDate;
  }
}

public partial class frmMain : Form
{
    private void monthCalendar1_SelectedDate(object sender, DateRangeEventArgs e)
    {
        var selectedDate = (DateTime.Parse(e.Start.ToShortDateString())).Day;
        frmEvent frmE = new frmEvent(selectedDate);
        frmE.Show();
    }
}
public partial class frmEvent : Form
{
    public int SelectedDate { get; set; }
    public frmEvent()
    {
        InitializeComponent();
    }
}

public partial class frmMain : Form
{
    private void monthCalendar1_SelectedDate(object sender, DateRangeEventArgs e)
    {
        var selectedDate = (DateTime.Parse(e.Start.ToShortDateString())).Day;
        frmEvent frmE = new frmEvent();
        frmE.SelectedDate = selectedDate;
        frmE.Show();
    }
}

Accessing instance variables of a super class, proper form

around this issue Example 1 is fine.
[super init] should be called from the init method of the sub class.
code :
- (id) init {
    self = [super init];
    if (self) {
        // Init
    }
    return self;
}

Accessing variables in other Windows Form class

I wish this help you So you have information in the parent form (form2) that you want to access in a method of the child form (form3).
Create properties in form3 for the information that it will need. When form2 creates an instance of form3 it should set those properties.
code :
//TODO: give real name; adjust type as needed
public string SomePropertyName { get; set; }
f3.SomePropertyName = "hello from form2";
f3.SomePropertyName = someVariableInForm2;

accessing form variables from class in dll

To fix this issue You didnot provide enough info for a personal answer. But here is how I'd access a form from a dll. Let's say we have a class withing a dll file that looks as follows:
code :
namespace smth
{
    public partial class mytest : Form
    {
        public TextBox txt;

        public mytest()
        {
            InitializeComponent();
        }
    }
}
Assembly assembly = Assembly.LoadFile("C:\\mydllfile.dll");
Type type = assembly.GetType("smth.mytest");
Form form = (Form)Activator.CreateInstance(type);

C++: Why accessing class data members is so slow compared to accessing global variables?

Hope that helps The difference between the two version is that in one case, the compiler has to load p and perform some computation with it, while in the other, you're using a global constant, which the compiler can probably just substitute directly. So in one case, the resulting code probably does this:
Load p. Call abs(a - b), name the result c Call pow(c, p), name the result d Call d.sum() (whatever that means), name the result e Calculate 1.0 / p, name the result i Call pow(e, i).

Accessing class variables from form validator method in angular 2

may help you . I finally found a solution.. It's not the most aesthetic one, but it works... I add a wrap function around the 'passwordAnswerRequirements' method and from there I was able to grab the service instance in put it in a local variable.
code :
  passwordAnswerRequirements() {
    let passwordRegexExp = this.regexService.getRegex('password');
    return (input: any) => {
      if (!input.root || !input.root.controls)
        return null;
      if (passwordRegexExp.test(input.value))
        return null;
      else
        return { notAcceptablePassword: true }
    };
  }
