Question

In my program.cs file, the code is as follows:

static void Main()
{
    Application.EnableVisualStyles();
    Application.SetCompatibleTextRenderingDefault(false);
    frmWizard frm = new frmWizard();
    Application.Run(frm);

    Thread th = new Thread(frm.ThreadSetCom);
    th.Start();
}

ThreadSetCom is a method that runs in an endless loop checking for something. I noticed that ThreadSetCom will only execute just before the WinForm appears and after i close the form. It doesn’t execute while the Form is visible. Can anyone clear this up to me please?

Answer 1

Application.Run waits until the passed form in argument is closed. You may need to create and start the thread in the load event of the frmWizard.

private void frmWizard_Load(object sender, System.EventArgs e)
{
    Thread th = new Thread(ThreadSetCom);
    th.Start(); 
}
