    <p>I'm trying to build a game 'blocks' which sees the matches cubes and delete them. This code makes two cubes and moves them along the y-axis. Then, it supposed to disappear and 100 cube in different places to appear. My problem is I don't know how to make the cubes look disappearing nor how to write the function 'cube generation' , I'm writing in 3d. Any help of what should I do.</p> <pre><code>using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using Tao.OpenGl; using System.Threading; using Tao.FreeGlut; namespace TAOSample { class VertexDania{ double vx, vy , vz; public double X{ get{return vx;} set{ vx = value;} } public double Y{ get{return vy;} set{ vy = value;} } public double Z{ get{return vz;} set{ vz = value;} } } public partial class Form1 : Form { public Form1() { InitializeComponent(); simpleOpenGlControl1.InitializeContexts(); Gl.glClearColor(1, 1, 0, 0); Gl.glClearDepth(1.0); Gl.glMatrixMode(Gl.GL_PROJECTION); Gl.glLoadIdentity(); Glu.gluPerspective(45, simpleOpenGlControl1.Height /(double)simpleOpenGlControl1.Width, 0.1, 1000); Gl.glViewport(0, 0, simpleOpenGlControl1.Width, simpleOpenGlControl1.Height); Tao.FreeGlut.Glut.glutInit(); } private void simpleOpenGlControl1_Paint(object sender, PaintEventArgs e) { Gl.glEnable(Gl.GL_LIGHTING); Gl.glEnable(Gl.GL_LIGHT0); Gl.glEnable(Gl.GL_COLOR_MATERIAL); Gl.glEnable(Gl.GL_DEPTH_TEST); Gl.glClear(Gl.GL_COLOR_BUFFER_BIT | Gl.GL_DEPTH_BUFFER_BIT); Gl.glLoadIdentity(); VertexDania[] points = new VertexDania[] { new VertexDania{X=0 , Y=0.73 , Z=-0.75}, new VertexDania{X=0.1 , Y=0.85 , Z=-0.75}, new VertexDania{X=-0.01 , Y=0.95 , Z=-0.75}, new VertexDania{X=-0.1 , Y=0.80 , Z=-0.75}, new VertexDania{X=0.1 , Y=0.65 , Z=-1}, new VertexDania{X=0 , Y=0.5 , Z=-0.75}, new VertexDania{X=-0.1 , Y=0.6 , Z=-1} }; VertexDania[] point = new VertexDania[] { new VertexDania{X=0, Y=0.23, Z=-0.75}, new VertexDania{X=0.1 , Y=0.35 , Z=-0.75}, new VertexDania{X=-0.01 , Y=0.45 , Z=-0.75}, new VertexDania{X=-0.1 , Y=0.30 , Z=-0.75}, new VertexDania{X=0.1 , Y=0.1 , Z=-0.75}, new VertexDania{X=0 , Y=0.0 , Z=-0.75}, new VertexDania{X=-0.1, Y=0.1, Z=-0.75} }; double[,] normals = new double[,] { {0,0,1}, {0,0,-1}, {0,0,-1} }; int[,] faces = new int[,] { {0 , 1 ,4 , 5}, {0 , 3 , 6 , 5}, {0, 3 , 2 , 1} }; Gl.glColor3d(1, 0, 0); Gl.glTranslated(0, ymove, 0.1); for (int i = 0; i &lt; faces.GetLength(0); i++) { Gl.glNormal3d(normals[i, 0], normals[i, 1], normals[i, 2]); Gl.glBegin(Gl.GL_QUADS); for (int j = 0; j &lt; 4; j++) { Gl.glVertex3d(points[faces[i, j]].X, points[faces[i, j]].Y, points[faces[i, j]].Z); } Gl.glEnd(); Gl.glNormal3d(normals[i, 0], normals[i, 1], normals[i, 2]); Gl.glBegin(Gl.GL_QUADS); for (int j = 0; j &lt; 4; j++) { Gl.glVertex3d(point[faces[i, j]].X, point[faces[i, j]].Y, point[faces[i, j]].Z); } Gl.glEnd(); } if (ymove &gt;= -3) ymove -= 0.03; } void redrawThread() { while (true) { Thread.Sleep(50); simpleOpenGlControl1.Invoke(new Action(delegate() { simpleOpenGlControl1.Draw(); })); } } private void Form1_Load(object sender, EventArgs e) { Thread t = new Thread(redrawThread); t.IsBackground = true; t.Start(); } private void simpleOpenGlControl1_Resize(object sender, EventArgs e) { Gl.glMatrixMode(Gl.GL_PROJECTION); Gl.glLoadIdentity(); Glu.gluPerspective(45, simpleOpenGlControl1.Width / (double)simpleOpenGlControl1.Height, 0.1, 100); Gl.glViewport(0, 0, simpleOpenGlControl1.Width, simpleOpenGlControl1.Height); // Gl.glMatrixMode(Gl.GL_MODELVIEW); } } } </code></pre>

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.
