    <p>I'm new to C# and threading and i have project where i have a game of Reversi(othello) which i have to make multi-threaded, after experimenting for days I'm no further forward. I have to separate the UI from the code, basically so the processes which take a while to load do not 'freeze' the program, allowing the user to access the buttons and user interface bits.</p> <p>I've looked into background worker, tasks, general threads.</p> <p>Here's a couple of key sections of code, when i click the move button i want the dowork method to run, leaving the UI interactive.</p> <pre><code> private void playerMoveButton_Click(object sender, EventArgs e) { _bw = new BackgroundWorker { WorkerReportsProgress = true, WorkerSupportsCancellation = true }; _bw.DoWork += bw_DoWork; if (_bw.IsBusy) _bw.CancelAsync(); } public void bw_DoWork(object sender, DoWorkEventArgs e) { if (gameOver) { moveLabel.Text = "Game Over"; moveTypeLabel.Text = ""; return; } // Now the computer plays moveLabel.Text = "My Move"; // Does it have any legal moves? int numComputerMoves = theGame.CountLegalMovesMoves(); if (numComputerMoves != 0) { if (computerPlayStyle == PlayStyle.RANDOM) { moveTypeLabel.Text = "Guessing..."; moveTypeLabel.Visible = true; this.Refresh(); // Sleep for a little to give player time to see what's // going on Thread.Sleep(1000); // get a move at random int[] movePos = theGame.FindRandomMove(); // make move theGame.MakeMove(movePos[0], movePos[1]); boardLayoutPanel.Refresh(); } else { moveTypeLabel.Text = "Thinking..."; moveTypeLabel.Visible = true; this.Refresh(); // Get best move int[] movePos = theGame.FindGoodMove(minimaxDepth); // make move theGame.MakeMove(movePos[0], movePos[1]); boardLayoutPanel.Refresh(); } } else { moveTypeLabel.Text = "I've no legal moves."; moveTypeLabel.Visible = true; this.Refresh(); // Sleep for a little to give player time to see what's // going on Thread.Sleep(1000); // Change current player theGame.SwapCurrentPlayer(); } //Reset for the player move moveLabel.Text = "Your Move"; int blackScore = theGame.BlackCellCount(); int whiteScore = theGame.WhiteCellCount(); string bscoreMsg = "Black: " + blackScore; string wscoreMsg = "White: " + whiteScore; blackScoreLabel.Text = bscoreMsg; whiteScoreLabel.Text = wscoreMsg; // Does player have any legal moves int numPlayerMoves = theGame.CountLegalMovesMoves(); if (numPlayerMoves == 0) { moveTypeLabel.Text = "You have no legal moves."; playerMoveOKButton.Visible = true; // If computer player has no legal moves game over! if (numComputerMoves == 0) { gameOver = true; } } else { moveTypeLabel.Text = "Select cell or choose"; randomMoveButton.Visible = true; playerMoving = true; } } </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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
