    <p>here is my code:</p> <pre><code>namespace WindowsFormsApplication1 { public partial class Form1 : Form { Point lastClick; private Dictionary&lt;Keys, bool&gt; keyIsDown = new Dictionary&lt;Keys, bool&gt;(); private Timer timer; private int stream1; public Form1() { InitializeComponent(); keyIsDown.Add(Keys.D1, false); keyIsDown.Add(Keys.D2, false); keyIsDown.Add(Keys.D3, false); keyIsDown.Add(Keys.D4, false); keyIsDown.Add(Keys.A, false); keyIsDown.Add(Keys.S, false); keyIsDown.Add(Keys.D, false); keyIsDown.Add(Keys.F, false); keyIsDown.Add(Keys.Z, false); keyIsDown.Add(Keys.X, false); keyIsDown.Add(Keys.C, false); keyIsDown.Add(Keys.V, false); this.KeyPreview = true; } private void Form1_KeyDown(object sender, KeyEventArgs e) { if (true == keyIsDown.ContainsKey(e.KeyCode)) { keyIsDown[e.KeyCode] = true; } } private void Form1_KeyUp(object sender, KeyEventArgs e) { if (true == keyIsDown.ContainsKey(e.KeyCode)) { keyIsDown[e.KeyCode] = false; } } private void Form1_Load(object sender, EventArgs e) { // This makes the computer constantly call the playKeys method timer = new Timer(); timer.Interval = 10000; timer.Tick += new EventHandler(playKeys); timer.Enabled = true; } private void playKeys(Object source, EventArgs e) { if (true == keyIsDown[Keys.D1]) { Beat1.Image = Beatpadpc.Properties.Resources.white_square_button; } else { Beat1.Image = Beatpadpc.Properties.Resources.black_square_button; } if (true == keyIsDown[Keys.D2]) { Beat2.Image = Beatpadpc.Properties.Resources.white_square_button; } else { Beat2.Image = Beatpadpc.Properties.Resources.black_square_button; } } </code></pre> <p>And what happens is this: </p> <pre><code>Key D1 down = key D1 white. Key D1 up = nothing happens until timer os over. Key D2 down = Key D1 black. Key D2 up = nothing happens until timer is over. Key D1 down = Key D2 black... etc... Key D1 down + Key D2 down = Key D1 white + Key D2 white. Key D1 up + Key D2 up = Key D1 and D2 stays the same until timer is over. It should be: Key D1 down = Key D1 white. Key D1 up = Key D1 black. Key D2 down = Key D2 white. Key D2 up = Key D2 black. </code></pre> <p>(Even if both keys are down or up it shouldn't affect the behavior of the other key).</p> <p>What it should happen when key is up should be immediately after the key is up, it only happens when its down.</p> <p>How do i fix this?</p>

    1. COThe 10 second timer is very mysterious. Just call playKeys() from your KeyUp and KeyDown methods.

    3. CO@HansPassant I think doing so he can't control the auto-repeating time (which should be 10 seconds).

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.
