"VB.net" text box shortcut key support

We know that the text box in vb.net is a shortcut key that does not support CTRL + A.

What if we let it support it?

1     Private SubTxtsql_keydown (ByValSender as Object,ByValE asSystem.Windows.Forms.KeyEventArgs)HandlesTxtsql.keydown2         IfE.keycode = KEYS.AAndAlso(E.keydata andKeys.control) Then3             'Select All4 Txtsql.selectall ()5         End If6     End Sub

The above code is an example.

E.keycode is the code that you press for the character class key, for example: a,b,c,1,2,3,;, ', [, and so on.

E.keydata means that you press the character-class key code encoded with the function key (such as ctrl,alt,shift, etc.) encoded in combination.

The e used here. KeyData and Keys.control are trying to get from E. Keydata extracts the CTRL key in the code, if the extraction succeeds, it means that the combination key is pressed, otherwise it is not pressed key combination.

In this example, the key combination of CTRL + A is checked, so the effect of caption description is achieved.
