?code

When I develop an application with VS.NET C#, when I click more than
one time on a button, it seems to execute many threads of the same
function.
How to disable it?
thanks
 
when you click the button, the first line of code should disable the button.

MyButton.Enabled = false;

Then call your code. When you are done with your operation, make sure to
re-enable the button.

Why on earth is C# doing this and who decided on something like that!!??
Just kidding, back from reading your blog... ;o)
 
?code,

It doesn't execute more than one thread unless you explicitly tell it
to. If you have code that creates a new thread, then that code is going to
run very fast, because it will spawn the new thread, and then that new
thread will execute new code parallel to the code running in the UI thread
(well, maybe not exactly, depending on number of processors, etc, etc).

What you need to do is set a flag indicating that you already spawned a
thread, and if that flag is set, do not spawn another thread when the button
is pressed.

Hope this helps.
 
I think threads should be subbed for buffered clicks?

I'm guessing that what's happening is a button is being clicked multiple
times, and am assuming there's some buffering mechanism in the windows
message handling. Would this not give the appearance of "multiple threads"?
