Execute specified function every X seconds

Question

I have a Windows Forms application written in C#. The following function checks whenever printer is online or not:

public void isonline()
{
    PrinterSettin         


        

Answer 1

The most beginner-friendly solution is:

Drag a Timer from the Toolbox, give it a Name, set your desired Interval, and set "Enabled" to True. Then double-click the Timer and Visual Studio (or whatever you are using) will write the following code for you:

private void wait_Tick(object sender, EventArgs e)
{
    refreshText(); // Add the method you want to call here.
}

No need to worry about pasting it into the wrong code block or something like that.
