sorry here it is

Pobiega•10mo ago

Okay, there is a whole pile of wrong here First: don't open new forms in another forms constructor. Especially not your main form. two:

Login loginWindow = new Login();
loginWindow.Show();
loginWindow.Close();

Login loginWindow = new Login();
loginWindow.Show();
loginWindow.Close();

This will open a new form to then immediately close it again

MementoMoriOP•10mo ago

yeah i tried doing .Close() but it dont work for the loginWindow i can only close it from Main um why

Pobiega•10mo ago

Because the main form isnt fully constructed at that point

MementoMoriOP•10mo ago

but it will construct right after Login is closed right

Pobiega•10mo ago

yes, in theory - but with winforms (and probably also WPF) the main form is treated differently it sounds like you should just hide the main form, create and show a login form once the main form has loaded (with the load event), then when the login form is done you can show the main form again HOWEVER this code:

Login loginWindow = new Login();
loginWindow.Show();
loginWindow.Close();

Login loginWindow = new Login();
loginWindow.Show();
loginWindow.Close();

will never work as you want after show, it will not "stop" to wait for you to finish logging in. it will instead move to .Close and close If you want the main forms code to "wait" for the login, you need to use ShowDialog() and then you also dont need to close it yourself

MementoMoriOP•10mo ago

yes i used this ShowDialog() but the thing is the login window wont close unless i press the close button for it i wanted for it to close when the user presses the button for which AttemptLogin runs

Pobiega•10mo ago

And that can be done. if you give your button a DialogResult value

MementoMoriOP•10mo ago

um how do i do that

Pobiega•10mo ago

step 1: add a Loaded event handler to your main form

Pobiega•10mo ago

Pobiega•10mo ago

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    var form = new LoginWindow();
    var result = form.ShowDialog();

    // do something with result here
    if (result == true)
    {
    }
}

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    var form = new LoginWindow();
    var result = form.ShowDialog();

    // do something with result here
    if (result == true)
    {
    }
}

Pobiega•10mo ago

in LoginWindows.xaml

Pobiega•10mo ago

private void Button_Click(object sender, RoutedEventArgs e)
{
    DialogResult = true;
}

private void Button_Click(object sender, RoutedEventArgs e)
{
    DialogResult = true;
}

MementoMoriOP•10mo ago

Pobiega•10mo ago

your program is already running close it before starting a new one

MementoMoriOP•10mo ago

yoo its fixed noww thank youu

leowest•10mo ago

@MementoMori tip, wpf does not work like winform u should learn MVVM and how to navigate instead of opening new window https://www.youtube.com/watch?v=N26C_Cq-gAY&list=PLZnwzjShc0PS1DDfPTW3oLSTsn878a6_P&index=22 might be a bit overwhelming at first for u, since ur new to it.
