Answer 1

Edit: I should mention I would not consider this to be a Best Practice

If you are using 3.5 you can make an extension method to the effect of:

public static void SafeInvoke(this Control control, Action handler) {
    if (control.InvokeRequired) {
        control.Invoke(handler);
    }
    else {
        handler();
    }
}

this is basically taken from: Here

Then use it like:

textBox1.SafeInvoke(() => .... );

Of course modify the extension etc for your usages.
