Exemples

L’exemple de code suivant montre comment gérer l’événement NodeMouseDoubleClick et comment utiliser .TreeNodeMouseClickEventArgs Pour exécuter cet exemple, collez le code dans un Windows Form qui contient un TreeView nommé treeView1. Renseignez treeView1 les noms des fichiers situés dans le c:\ répertoire du système sur lequel l’exemple s’exécute et associez l’événement NodeMouseDoubleClick de treeView1 à la treeView1_NodeMouseDoubleClick méthode de cet exemple.

    // If a node is double-clicked, open the file indicated by the TreeNode.
private:
    void InitialTreeView_NodeMouseDoubleClick(Object^ sender,
        TreeNodeMouseClickEventArgs^ e)
    {
        try
        {
            // Look for a file extension.
            if (e->Node->Text->Contains("."))
            {
                System::Diagnostics::Process::Start("c:\\" + e->Node->Text);
            }
        }
        // If the file is not found, handle the exception and inform the user.
        catch (System::ComponentModel::Win32Exception^)
        {
            MessageBox::Show("File not found.");
        }
    }

// If a node is double-clicked, open the file indicated by the TreeNode.
void treeView1_NodeMouseDoubleClick(object sender, TreeNodeMouseClickEventArgs e)
{
    try
    {
        // Look for a file extension.
        if (e.Node.Text.Contains("."))
            System.Diagnostics.Process.Start(@"c:\" + e.Node.Text);
    }
        // If the file is not found, handle the exception and inform the user.
    catch (System.ComponentModel.Win32Exception)
    {
        MessageBox.Show("File not found.");
    }
}

' If a node is double-clicked, open the file indicated by the TreeNode.
Sub treeView1_NodeMouseDoubleClick(ByVal sender As Object, _
    ByVal e As TreeNodeMouseClickEventArgs) _
    Handles treeView1.NodeMouseDoubleClick

    Try
        ' Look for a file extension, and open the file.
        If e.Node.Text.Contains(".") Then
            System.Diagnostics.Process.Start("c:\" + e.Node.Text)
        End If
        ' If the file is not found, handle the exception and inform the user.
    Catch
        MessageBox.Show("File not found.")
    End Try
