    <p>Forgive me if this question is a duplicate of others, I probably do not know how to word out my problem correctly that's why I could not find the appropriate answer.</p> <p>I have a winforms C# application with multiple forms. My main form is a login form, prior to it is a splash screen which loads first. My problem is that whenever I click logout, I want it to return to the login screen. However, the splash screen loads and does not open the login form anymore. </p> <p>I suspect that this is because I started a new thread to be able to close the mainform and open the next form? I read it somewhere that I have to do that because an error occurs when merely using main.close() and form1.show(). Help?</p> <p><strong>SPLASH SCREEN CODE</strong></p> <pre><code>public SplashScreen() { InitializeComponent(); } private void timer1_Tick(object sender, EventArgs e) { progressBar1.Increment(1); if (progressBar1.Value == 100) timer1.Stop(); } </code></pre> <p><strong>LOGIN START</strong></p> <pre><code>public LOGIN() { Thread t = new Thread(new ThreadStart(SplashScreen)); t.Start(); Thread.Sleep(5000); InitializeComponent(); t.Abort(); } public void SplashScreen() { Application.Run(new SplashScreen()); } </code></pre> <p><strong>LOGIN EXIT</strong> (Redirected to user's home page)</p> <pre><code>public static void OpenHomeAdmin() // new thread to open home ADMIN { Application.Run(new Home_Admin()); } if (usertype == "UT1") //admin rights { //GET LOGGED USER Home_Admin homeAdmin = new Home_Admin(); homeAdmin.SetUsername(username); this.Close(); System.Threading.Thread t = new System.Threading.Thread(new System.Threading.ThreadStart(OpenHomeAdmin)); t.Start(); } </code></pre>

    1. CO`Application.Run(Form)` is used to run a new application on the current thread. Is that your intention? Are you just trying to display new forms?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
