Requesting a computation to wait

Requesting a computation to wait

  You can try calling Application.DoEvents(), although if it's all in one spot, in a single thread, I don't see why you'd have to.

  Ah... I thought you had a messagebox, but it's a label, so DoEvents is what you needed. That call forces the app to let paint events etc run before it continues.

  The lightbulb was caused by the stupid emoticons. Oh, how I hate them.

  Your reply solved the problem, and I am very grateful. And since you expressed some doubts as to the necessity of doing it, I am enclosing the section of code concerned.

  private void ReadyToCompute()

  {

  oF = iF + "-out.raw";

  label3.Text = oF;

  oL = fL + iL;

  label6.Text = "Will contain "

  + oL.ToString() + " binary entries";

  progressBar1.ForeColor = Color.Red;

  progressBar1.BackColor = Color.White;

  progressBar1.Value = 0;

  progressBar1.Visible = true;

  Application.DoEvents();

  Compute_();

  return;

  }

  private void Compute_()

  {

  FileStream oFS = new FileStream(oF, FileMode.Create);

  if (Text3.Checked)

  ;

  else

  {

  oBW = new BinaryWriter(oFS);

  double[] oValues = new double[oL];

  MaxOut = 0.0;

  progressBar1.Maximum = oL;

  for (i = 0; i < oL; i++)

  {

  oValues = 0;

  for (j = 0; j < Math.Min(fL, i); j++)

  if (i - j < iL)

  oValues += fValues[j] * iValues[i - j];

  if (i % 1000 == 0) progressBar1.Value = i;

  }

  for (i = 0; i < oL; i++)

  {

  V = oValues;

  if (V < 0) V = -V;

  if (V > MaxOut) MaxOut = V;

  }

  factor = 32000.0 / MaxOut;

  for (i = 0; i < oL; i++)

  {

  oValues *= factor;

  oBW.Write(Convert.ToInt16(oValues));

  }

  }

  return;

  }

  The statement in question is at the end of the first section of code, followed by the call to Compute_(). If I comment out "Application.DoEvents" the whole computation in "Compute_()" is done before the messages in "ReadyToCompute()" appear.

  And by the way, I don't know where the lightbulbs appeared in my code section! They were originally "[some index]".
