Question

I seem to have a problem executing commands in the correct order, I have a method in my Program:

private void  GenerateButton_Click(object sender, EventArgs e)
{
    Statuslabel.Text = "Working...";

    LongMethod();
    //Call to another Method of another class which takes 15-20 seconds to execute

    Statuslabel.Text = "Done";
}

the problem seems to be that instead of assigning “Working” to the status label and THEN calling the LongMethod, the Program seems to execute LongMethod() first, and then it changes Status Label’s text to “Working” for a split second and then immediately changes it to “Done”.
Oh, and the UI is locked up during the LongMethod() execution, because the Program is SingleThreaded.

I tried threads earlier, but for the life of me I couldn’t get the syntax right, I tried:

Thread MyThread = new Thread(LongClass.LongFunction);

Thread MyThread = new Thread(new ThreadStart(LongClass.LongFunction));

Where LongClass is the class which contains LongFunction as a static method.
I will check out the background worker now.

Answer 1

You should execute LongMethod on another thread so that the UI thread doesn’t block while it’s running.
