Hi Pankaj,

You were trying to modify a UI component (a label) from a thread other than the UI thread. To fix the problem, you can use if (Label1.InvokeRequired) in the code snippet earlier in the post to marshall the call back to the UI thread. I hope this helps.

Hi Kerry,
I am stuck with the same problem as you mentioned in your post and that is i am calling a function form a buttons click.

private void TimerCallBackHandler(object state) {

Label l = new Label();

l.Left = 10;

l.Top = 10;

l.Text = “Test “;

this.Controls.Add(l);

}

and i am getting the same error

InvalidOperationexception was unhandled

Cross-thread operation not valid: Control ‘Label1’ accessed from a thread other than the tread it was created on.

Plese help me how can i solve this problem.
Thanks in advance…..[:)]
