    <p>How do i add an entry in a listbox in a window that is in another thread. My Problem is, that i have to threads. One working thread, that does all the actual work and one thread for a window where i want to display status information. I tried to pass the form window as paramater in the constructor, but when i call it i get an exception.</p> <p>Here is some of my code to illustrate the problem:</p> <pre><code>public partial class Mainform : Form { private string db = String.Empty; private string password = String.Empty; private string sqlinifile = String.Empty; DatabaseListener dbListener; StatusWindow statusWindow; public Mainform() { // // The InitializeComponent() call is required for Windows Forms designer support. // InitializeComponent(); // // TODO: Add constructor code after the InitializeComponent() call. // db = "EWAG"; password = "secret"; sqlinifile = "C:\\Programme\\Unify\\Team Developer 5.2\\sql.ini"; textBoxDB.Text = db; textBoxPwd.Text = password; textBoxSqlIni.Text = sqlinifile; statusWindow = new StatusWindow(); dbListener = new DatabaseListener(statusWindow); } public void threadStarter() { this.dbListener.startSynchronizing(5); } void Button1Click(object sender, EventArgs e) { this.db = textBoxDB.Text; this.password = textBoxPwd.Text; this.sqlinifile = textBoxSqlIni.Text; if (dbListener.connectToDatabase(db,"sysadm", password, sqlinifile)) { this.Hide(); statusWindow.Show(); Thread synchronizer = new Thread(new ThreadStart(threadStarter)); synchronizer.Start(); } } } </code></pre>

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.
