❔ How do I close the authorization window after the user has logged in?

I implemented it this way, but in this case my memory is heavily loaded, so a new window is created every time

IKD IKD = new IKD();
                IKD.Show();
                Hide();

IKD IKD = new IKD();
                IKD.Show();
                Hide();

perhaps show it as a dialog instead? IDK.ShowDialog()

ApathyErrOP•2y ago

It works. And how to hide the authorization window so that it is not visible when the IKD is open?

Pobiega•2y ago

not enough information. You've shown literally 3 lines of code. I dont know what your "authorization window" is I thought that was the IKD

LoginWindow:

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        public void button1_Click(object sender, EventArgs e)
        {
            if (textBox1.Text == "123" && textBox2.Text == "")
            {
                Form1 newForm = new Form1();
                IKD newForm1 = new IKD();
                newForm1.ShowDialog();
                Hide();
            }
        }

        private void pictureBox1_Click(object sender, EventArgs e)
        {

        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void checkBox1_CheckedChanged(object sender, EventArgs e)
        {

        }

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        public void button1_Click(object sender, EventArgs e)
        {
            if (textBox1.Text == "123" && textBox2.Text == "")
            {
                Form1 newForm = new Form1();
                IKD newForm1 = new IKD();
                newForm1.ShowDialog();
                Hide();
            }
        }

        private void pictureBox1_Click(object sender, EventArgs e)
        {

        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void checkBox1_CheckedChanged(object sender, EventArgs e)
        {

        }

IKD:

public IKD()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
           
            Form1 Form1 = new Form1();
            this.Close();
        }

public IKD()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
           
            Form1 Form1 = new Form1();
            this.Close();
        }

Pobiega•2y ago

ok so IKD owns Form1 ah I see, you actually have a weird loop

ApathyErrOP•2y ago

yep

Pobiega•2y ago

IKD creates and owns a form 1, but a Form1 also creates/owns an IKD.. and another form1? do you understand what happens each time you do new Form1();?

ApathyErrOP•2y ago

LoginWindow=Form1 no

Pobiega•2y ago

it creates a NEW form instance unrelated to the previous ones

ApathyErrOP•2y ago

o no how to avoid this? I just don't understand how to do it right without creating unrelated windows.

Pobiega•2y ago

you need to reuse and pass your object references around first, which form is your main form, the one that loads when your program starts?

ApathyErrOP•2y ago

Form1, which is the authorization window .

Pobiega•2y ago

Okay. So, there are a few ways to do this. Are there ever a reason to show the login form again after the user goes through it the first time?

Pobiega•2y ago

Im in the middle of some stuff, I can help in 20ish min

ApathyErrOP•2y ago

no prob

Pobiega•2y ago

Ok so the idea is that you in Form1 create a single IKD instance, probably as a field

public partial class Form1 : Form
{
    private IKD _ikd = new();
    
    public Form1()
    {
        InitializeComponent();
    }
...

public partial class Form1 : Form
{
    private IKD _ikd = new();
    
    public Form1()
    {
        InitializeComponent();
    }
...

in your button click event, you do

this.Hide();
_ikd.Show();

this.Hide();
_ikd.Show();

nothing else. and in IKD, remove this:

  Form1 Form1 = new Form1();
            this.Close();

  Form1 Form1 = new Form1();
            this.Close();

you said there was no point in "going back" from IKD, so lets remove that

ApathyErrOP•2y ago

I probably will, but I would still like to try to do it in order to use it in the future

Pobiega•2y ago

? I don't follow.

ApathyErrOP•2y ago

I'm still trying to implement it as you showed above, but I can't. Before that there was an error "Please use language version 9.0 or greater", but I have already fixed it

Pobiega•2y ago

thats the IKD code it cant use the _ikd variable, thats only in Form1

Please use language version 9.0 or greater

oh no, are you using .NET Framework 4.x instead of .NET 7?

ApathyErrOP•2y ago

yes, this is the latest version that is available when creating a WinForms project

Pobiega•2y ago

it is not you absolutely can make winforms projects on .NET 7 $newproject

MODiX•2y ago

When creating a new project, prefer using .NET over .NET Framework, unless you have a very specific reason to be using .NET Framework. .NET Framework is now legacy code and only get security fix updates, it no longer gets new features and is not recommended. https://cdn.discordapp.com/attachments/569261465463160900/899381236617855016/unknown.png

ApathyErrOP•2y ago

should I have chosen the second when creating the project?

Pobiega•2y ago

yes

ApathyErrOP•2y ago

Okay, thx ❤️
