I'm working on a search program and would like to have a national instruments led control blinking during the search. The led needs to be started on its own thread while the search runs on a separate thread. This is my first attempt at multi-threading in c# and I'm not sure what to try.
Here is my c# code, I'm trying to start the LED blinking then run the search then stop the LED blinking. The LEDON() and LEDOFF() work if run separately.
Code:
private void btnSearch_Click(object sender, EventArgs e)
{
Thread LEDStart = new Thread(LEDON); //Creates a Thread that will call LEDON()
LEDStart.Start();
int i;
string temp = "*" + textBoxFileName.Text + "*";
string[] AllFiles = Directory.GetFiles(this.textBoxFolderpath.Text, temp, SearchOption.AllDirectories);
for (i = 0; i < AllFiles.Length - 1; i++)
{
progressBar1.Maximum = AllFiles.Length - 1;
string[] row = new string[] { Path.GetFileName(AllFiles[i]), AllFiles[i] };
dataGridView1.Rows.Add(row);
progressBar1.Increment(1);
if (progressBar1.Value == progressBar1.Maximum)
{
Thread LEDEND = new Thread(LEDOFF); //Creates a Thread that will call LEDOFF()
LEDEND.Start();
}
}
}
//Turn On LED
private void LEDON()
{
if (this.led1.InvokeRequired)
{
this.led1.Invoke(new MethodInvoker(() => LEDON()));
return;
}
