    <p>Whenever I call the method Draw in Sprite, it won't draw it because X, Y, Width and Height are 0. :(</p> <p>code:</p> <pre><code>class Sprite { protected int Y;// { get; set; } protected int X;// { get; set; } { get; set; } protected int Width;// { get; set; } { get; set; } public int Height;// { get; set; } { get; set; } protected Image image;// { get; set; } { get; set; } public Sprite() { } public void Draw(Graphics drawArea) { Image sImage = Image.FromFile("alien.jpg"); drawArea.Clear(Color.White); drawArea.DrawImage(sImage, X, Y, Width, Height); } } class User:Sprite { public User() { } public User(int width, int height, int userWidth, int userHeight) { Sprite sprite = new Sprite(); Image UserImage = Image.FromFile("alien.jpg"); X = width; Y = height; Width = userWidth; Height = userHeight; image = UserImage; } } </code></pre> <p>ps: sprite.Draw is declared in another method in another class, but that all should work just fine. Thanks for helping and probably saving me hours of time :) </p> <p>Nick</p> <p><strong>EDIT</strong></p> <p>here is the subclass which gives the parameter and other stuff.</p> <pre><code> Alien mAlien; User mUser; protected int mLevel; public gameLogic() { } public gameLogic(int width, int height, int level) { mUser = new User(width / 2, height - 30, 30, 30); mAlien = new Alien(width / 2, 5, 30, 30, "alien.jpg", 10 * level); mLevel = level; } public void drawAll(Graphics drawArea) { Sprite sprite = new Sprite(); sprite.Draw(drawArea); } </code></pre> <p>Im sorry for all these errors that'll probably occur, Im a new student :)</p>

    1. COIt is not clear what you are asking for and where the problem is - try improving your question. However the line `Sprite sprite = new Sprite();` in the constructor of `User` derived from `Sprite` looks suspicious.

    2. COThe `user` is a dervied class, it does not need its own Sprite property as it is a sprite. so you can removethe `Sprite sprite = new Sprite();` line. As for the UserImage, it is being assign to your `image` property, although `image` never gets used by your spirte base class. Can you please add in the code you use to declare a user

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.
