C#: Need text to display on a button for set time.

[Cassius]

So I'm trying to get text to display on one of 5 buttons for an amount of time and then go back to not having anything on it. Seems like it should be simple, but I've spent hours trying to do this and I can't figure it out. I am able to randomly choose a button and put the text on, but I can't figure out how to have that text only stay for an amount of time and then disappear. Any help would be appreciated.

Simple, just create a timer, set it's resolution to 5000ms, and create an event handler for Tick();

In the event handler, just generate a random number, and change the texts of the buttons accordingly.

 

[Cassius]

Is there a way to pass to the event handler which button to change the text on?

Thanks for the feedback I finally figured out how to do it. Here is my code:

private void ClearButton(object sender, EventArgs e)
{
Timer temp = (Timer)sender;
int button = Convert.ToInt16(temp.Tag.ToString());

switch (button)
{
case 1:
game.button1.Text = "";
break;
case 2:
game.button2.Text = "";
break;
case 3:
game.button3.Text = "";
break;
case 4:
game.button4.Text = "";
break;
case 5:
game.button5.Text = "";
break;
}
}

Be careful there, Cassius. I think there is a possible deadlock situation in that code you posted. I think (I don't remember, but you'll have to make sure) that the Timer delegate is invoked on a .NET ThreadPool thread - which means the work is being done on a thread that is different than the UI thread. You can't access the UI controls directly (which is what your code suggests) from a background/worker thread.

Look up MSDN for the details.
