A simple solution is to force immediate redraw of the label using the Refresh method.

C#

label1.text="hai";
label1.Refresh();
JukeBox_Timer.Stop();
JukeBox_Timer.Start();

thread.sleep(3000);
clearfstext(pagenation_value);

settheme("\\Page Selection.swf");

Solution 1

lable1.Text = "hai"; doesn't get executed immediately. Like all GUI operations, it gets queued inernally until the next UI redraw. But the UI thread is blocked by thread.Sleep(3000);.

So you need to execute the sleep part in a worker thread. Something like

C#

private void DelayedMethod()
{
    System.Threading.Thread.Sleep(3000);

    SetTheme("Whatever");
}

void YourCurrentMethodOnUiThread()
{
    label1.Text = "hai";

    System.Threading.Thread otherThread = new System.Threading.Thread(DelayedMethod);
    otherThread.Start();
}
