hi all, I have some problem on a Windows application in .Net Framework,just
as below:
private void button1_Click(object sender, System.EventArgs e)
{

WindowsApplication1.localhost.Service1 ser=new
WindowsApplication1.localhost.Service1();
textBox1.Text=ser.Add(int.Parse(textBox1.Text),1).ToString();
MessageBox.Show("ok");

}
you know, A webservice named ser is called in the above function,and ,when
the main form is loaded for the first time,if I click the button1 on the
form very quickly,the awful thing would happen:a messagebox is showed,when I
close it ,another messagebox is opened,I continue closing, and the same
thing happen:a messagebox is showed.The number of messageboxes is according
to the speed of my mouse clicking.

so, it seems the button1 still accept the click event while a webservice is
being called for the first time.But I expect only one messagebox would be
showed even though I click very quickly.How to control? hope your help!!!
Thank you!

When a button is clicked, it raises a Click event. your button1_Click method
handles that event. Naturally, when you click the button multiple times,
button1_Click is called multiple times.

In order to answer your question, you have to ask yourself, "why would it
_not_ raise the Click event? What would prevent it?"

Why did you expect that would happen? It happened the first time, didn't it?
And you didn't do anything to prevent it, did you?
