In many countries in the world, a video game must be submitted to a ratings body to determine how violent, scary, or sexually explicit it is before it may be sold This is done after the game reaches beta, when all the content is present The rating institution takes a few days or weeks to examine the game and return a rating, which the publisher is required to print on the game s box and possibly in any future advertising as well In America, rating is done by the Entertainment Software Rating Board This is not required by law (that would be a violation of the First Amendment), but some retailers refuse to carry games that have not been ESRB-rated Some also refuse to carry games with an AO (Adults Only) or M (Mature) rating Although many developers object to having their games labeled in this way, the system does help the consumers know what it is they re getting It is actually superior to the American movie-rating system, because in addition to a letter grade it also supplies content descriptors short phrases that indicate what sorts of things the player will see in the game Obtaining the ratings for every country in which the game will be sold is a major job, and most publishers have a special department set up just to handle the paperwork and keep track of the process for each game

// Search for a matching node foreach (TreeNode n in node.Nodes) { string nodePath = n.Tag as string; if (nodePath == fileName) { // Found it! return n; }

} return null;

With these changes in place, we can revamp our ItemActivate handler to select the corresponding tree node.

Quality assurance sounds like a fancy term for testing, but in fact it refers to a particular aspect of the process Normally, a game goes to QA when all the bugs in the bug database are fixed and the producer is convinced the game is ready to ship The QA department tests it for a number of hours, and gives it a simple pass/fail grade QA doesn t try to determine whether a game is enjoyable or well-balanced; it is concerned only with whether it works as a piece of software If a game ever crashes, responds inappropriately to a command, or displays something it isn t supposed to display, it fails QA and cannot be shipped QA also checks to make sure that all the details in the manual are correct:

that the images on the screen match the pictures in the manual, and that the commands are documented correctly and work as described The QA department at a publisher is normally separate from, and independent of, the production department that is responsible for the game That way they can t be pressured into passing the game even if it has problems

if (listViewMain.SelectedItems.Count > 0) { // Find the file path for selected item string fileName = null; ListViewItem item = listViewMain.SelectedItems[0]; if (_albumsShown) { // Get the file for this album fileName = item.Tag as string; } else if (item.Tag is int) { // Use the index of the photograph int index = (int)item.Tag; fileName = _album[index].FileName; } if (fileName == null) { MessageBox.Show("This item cannot " + "be opened."); return; } // Find tree node with identical path TreeNode node = FindNode(fileName, true); if (node != null) { // Select the node to activate it. node.EnsureVisible(); treeViewMain.SelectedNode = node; } } }

a. If albums are displayed, the Tag property contains the album path. b. If photographs are displayed, the Tag property contains the index of this photo in the album.

If a file name is found, locate the TreeNode corresponding to this item. If the node is found, a. Make sure the node is visible. b. Select the node.
