Question

I’m trying a ProgressBar with the Marquee style. I set MarqueeAnimationSpeed to 0 initially and then I have a button than when pressed it looks for the instances of Sql Server. However, when I click start the progress bar does not show anything. I’m on Windows 7 I don’t know if this might be the problem

public Form1 ()
{
    InitializeComponent ();             
}

private void Form1_Load (object sender, EventArgs e)
{
    this.progressBar1.MarqueeAnimationSpeed = 0;
}

private void button1_Click (object sender, EventArgs e)
{
     this.progressBar1.MarqueeAnimationSpeed = 50;

     SqlDataSourceEnumerator sqlEnumerator = SqlDataSourceEnumerator.Instance;
     DataTable dataTable = sqlEnumerator.GetDataSources ();

     this.Close ();
}

Answer 1

More than likely your sqlEnumerator.GetDataSources (); is blocking the main thread and that’s why you’re not seeing it animate. Thread that call and you’ll see the marquee scrolling as it should.
