I am using a form with multiple text boxes. I have entered code for a keypress event that accepts the Enter key, which moves focus to the next text box. When the app is running and I press the Enter key to step to the next text box, I hear the selected windows sound for an error. If I press the Tab key, I do not get the sound. I do not want to turn the sound off in the Windows control panel - sounds. How can I disable the sound at the instant I press the Enter key? I do not want to disable the sound entirely, when the app is running.
