KeyDown event sound problem.

The KeyPreview is set to true, and then the SendKey method is written in the KeyDown event of the form. After pressing Enter, Send is the "TAB" key.
The function is implemented. No problem. My problem is that every time I hit enter, the computer will make a "dang" sound. How can I remove this sound?

That sound doesn't seem to come out through the speaker.
It is said that there is a small sound device on the motherboard, see the Beep, MessageBeep function of Win32 api.

There is always a small speaker on the motherboard. This kind of default sound is to be turned off by default in the control panel of the operating system-> Sound Multimedia.

It is not so exaggerated, I have resolved it myself.
It can be solved with code.
