WinForm implements page button timing hiding function

This article describes the implementation of the page button timing hiding function in WinForm. Share it for your reference, as follows:

Sometimes when making a program, you need to display an item on the page, and then disappear after a period of time. At this time, it can be achieved through timer timing.

private void Form1_Load(object sender, EventArgs e)
{
   t = new (3000);
   += new (OnTimedEvent);
   = true;
   = false;
}

Then inOnTimedEventWrite the corresponding code in the event, columns such as: = false;At this time, we will find that these two are not the same thread, so we need to use a delegatedelegateTo implement cross-threading

Define a delegate

private delegate void SetVisibleCallback();
//Call the following method in the place where the value is assignedprivate void SetVisible()
{
  // InvokeRequired needs to compare the calling thread ID and the creating thread ID  // Return true if they are not the same  if (this.)
  {
    SetVisibleCallback d = new SetVisibleCallback(SetPan);
    (d);
   }
   else
   {
    this. = false;
   }
}

This is called in the event generated by the timerSetVisible()Just

private void OnTimedEvent(object sender,  e)
{
  SetPan();
}

Of course, if you don't need to delegate implementation, you canOnTimedEventWrite in events

CheckForIllegalCrossThreadCalls = false;///// Avoid cross-threading problems = false;
