Subjects at integrity level C can only invoke a subject at the same or lower integrity level. The model was developed to thwart untrusted code from changing data or other code. This is achieved by making the levels of trust explicit with a “credibility rating” based on estimate of the cod...
The following code example demonstrates a use of the BeginInvoke method. C# Kopieren public delegate void InvokeDelegate(); private void Invoke_Click(object sender, EventArgs e) { myTextBox.BeginInvoke(new InvokeDelegate(InvokeMethod)); } public void InvokeMethod() { myTextBox.Text = "Executed ...
