Question

Ok so I am trying to pass a boolean from my Login form to my Home form, normally this would be fine for me and I would just use a property. However I thought I could use a similar method this time but I am implementing the singleton factory on the forms.

Here is the Login code relevant to this:
The AdminAccess property gets set fine and I have checked the value is correct.

private bool adminAccess;

public bool  AdminAccess
    {
        get { return adminAccess; }
        private set { adminAccess = value; }
    }

private void btnLogin_Click(object sender, EventArgs e)
    {
        //Some Code Does Stuff

         OpenHome();
    }

private void OpenHome()
    {
        HomeForm CreateHomeForm = HomeForm.HomeUI;
        CreateHomeForm.StartupHome = this;

        //Trying to set the property.
        CreateHomeForm.AdminPermissions= this.AdminAccess;

        CreateHomeForm.Show();
        this.Hide();
    }

Here is the relevant code from the Home form:

public HomeForm()
    {
        InitializeComponent();
        //just to check what is in the property quickly
        textBox1.Text = AdminPermissions.ToString();
    }

private bool adminPermissions;
public bool AdminPermissions
    {
        private get { return adminPermissions; }
        set { adminPermissions = value; }
    }

public Form StartupHome
    {
        set;
        get;
    }

private static HomeForm homeUI;
public static HomeForm HomeUI
    {
        get
        {
            if (homeUI == null || homeUI.IsDisposed)
            {
                homeUI = new HomeForm();
            }
            return homeUI;
        }
    }

The value gets reset when the HomeUI if loop runs as a new instance of the form is created. I can’t seem to think how to modify this to get a working solution. As you can tell I am fairly amateur so I’m just looking for a quick and clean solution to this 🙂
Thank you very much for your time in advance!

You assign the value in the constructor, BEFORE the AdminPermissions property is actually set. Change your code like this

public class HomeForm
{
    public HomeForm()
    {
        InitializeComponent();
    }

    private bool adminPermissions;  
    public bool AdminPermissions
    {
        get { return adminPermissions; }
        set { 
            adminPermissions = value;
            textBox1.Text = value.ToString();
        }
    }

    ...
}
