public static int Execute(Instance instance, IZennoPosterProjectModel project)

    // clear cookie
    instance.ClearCookie();
    
    // go to zennolab.com
    Tab tab = instance.MainTab;
    if ((tab.IsVoid) || (tab.IsNull)) return -1;
    if (tab.IsBusy) tab.WaitDownloading();
    tab.Navigate("zennolab.com");
    if (tab.IsBusy) tab.WaitDownloading();
    
    // get all documents
    DocumentCollection docCol = tab.AllDocuments;
    
    // go to lessons.zennolab.com
    tab.Navigate("lessons.zennolab.com");
    if (tab.IsBusy) tab.WaitDownloading();
    
    // add range to collection
    docCol.AddRange(tab.AllDocuments);
    
    // if any error
    if (docCol.ErrorDetected) return -1;
    
    return 0;
}

public static function Execute($instance, $project)
{
    // clear cookie
    $instance->ClearCookie();
    
    // go to zennolab.com
    $tab = $instance->MainTab;
    if (($tab->IsVoid) || ($tab->IsNull)) return -1;
    if ($tab->IsBusy) $tab->WaitDownloading();
    $tab->Navigate("zennolab.com");
    if ($tab->IsBusy) $tab->WaitDownloading();
    
    // get all documents
    $docCol = $tab->AllDocuments;
    
    // go to lessons.zennolab.com
    $tab->Navigate("lessons.zennolab.com");
    if ($tab->IsBusy) $tab->WaitDownloading();
    
    // add range to collection
    $docCol->AddRange($tab->AllDocuments);
    
    // if any error
