    <p>I need to pass information from thread of scanning data to recording information thread(write to xml file). It should looks something like this:</p> <p>Application.Run() - complete</p> <p>Scanning thread - complete</p> <p>Writing to xlm thread - ???</p> <p>UI update thread - I think I did it</p> <p>And what i got now:</p> <pre><code> private void StartButtonClick(object sender, EventArgs e) { if (FolderPathTextBox.Text == String.Empty || !Directory.Exists(FolderPathTextBox.Text)) return; { var nodeDrive = new TreeNode(FolderPathTextBox.Text); FolderCatalogTreeView.Nodes.Add(nodeDrive); nodeDrive.Expand(); var t1 = new Thread(() =&gt; AddDirectories(nodeDrive)); t1.Start(); } } private void AddDirectories(TreeNode node) { string strPath = node.FullPath; var dirInfo = new DirectoryInfo(strPath); DirectoryInfo[] arrayDirInfo; FileInfo[] arrayFileInfo; try { arrayDirInfo = dirInfo.GetDirectories(); arrayFileInfo = dirInfo.GetFiles(); } catch { return; } //Write data to xml file foreach (FileInfo fileInfo in arrayFileInfo) { WriteXmlFolders(null, fileInfo); } foreach (DirectoryInfo directoryInfo in arrayDirInfo) { WriteXmlFolders(directoryInfo, null); } foreach (TreeNode nodeFil in arrayFileInfo.Select(file =&gt; new TreeNode(file.Name))) { FolderCatalogTreeView.Invoke(new ThreadStart(delegate { node.Nodes.Add(nodeFil); })); } foreach (TreeNode nodeDir in arrayDirInfo.Select(dir =&gt; new TreeNode(dir.Name))) { FolderCatalogTreeView.Invoke(new ThreadStart(delegate {node.Nodes.Add(nodeDir); })); StatusLabel.BeginInvoke(new MethodInvoker(delegate { //UI update...some code here })); AddDirectories(nodeDir); } } private void WriteXmlFolders(DirectoryInfo dir, FileInfo file) {//writing information into the file...some code here} </code></pre> <p>How to pass data from AddDirectories(recursive method) thread to WriteXmlFolders thread?</p>

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.
