Winform suddenly does not respond to KeyEvent_PHP tutorial

Winform suddenly stopped responding to KeyEvent

In the beginning, WINFORM's KeyEvent was valid.

After using some controls to set their MouseEvent, Winform suddenly stopped responding to KeyEvent! !

You can solve it by following the steps below:

1. Try setting Form.KeyPreview to True first.

The function of KeyPreview is to determine whether the keyboard events of the controls on the form have been registered with the form. After I pressed the above settings, the Form's KeyEvent became alive again.

If it still doesn’t work, press 2.

2. This function needs to be overloaded

protected override bool ProcessDialogKey(Keys keyData)
