In my form’s constructor, I call:
InitializeComponent(); // boilerplate placed by VS, initializing controls
label1.BeginInvoke(new InvokeDelegate(RefreshLabelDelegate));
Yet, I get the dreaded exception with the message:
“Invoke or BeginInvoke cannot be called on a control until the window
handle has been created”
AFAIK, it is all the same thread, so why the exception?
Move
label1.BeginInvokefrom constructor toForm_Loadevent handler.
