Changing a WinForms Control on the 'UI' Thread from another Thread

Added: This article[^] has some interesting stuff about potential bugs with InvokeRequired - worth a read!

This comes up time and again.
Luc[^] has a great article explaining all here[^].

For those just wanting the solution...

public void WithParameterMethod(int parameter)
{
    if (InvokeRequired)
        Invoke(new MethodInvoker(
            delegate
            {
                // Call your method again
                WithParameterMethod(parameter);
            }
            ));
    else
    {
        // Do your thing here!
    }
}

public void NoParameterMethod()
{
    if (InvokeRequired)
        Invoke(new MethodInvoker(
            // Call your method again
            NoParameterMethod
            ));
    else
    {
        // Do your thing here!
    }
}
