Question

Which property of the KeyPress procedure’s e parameter is used to determine the key
pressed by the user?

Expert Solution

Step 1

Property used to determine the key pressed by the user:

If a key is pressed within a control (i.e. the control has been focused), then the KeyPress event will occur.
When a user is pressing a key on a control, then the KeyPress event occurs.

Step 2

The pressed key is sent to the KeyPress event’s e parameter.
- So, if the user presses a key, then the pressed key can be determined by using e parameter’s KeyChar property.
The format to determine the pressed key is given below:

e.KeyChar = key_Value

The If statement to determine the pressed “$” key is given below:

If e.KeyChar = “$” Then

In the above statement, the “e.KeyChar” represents the key entered by the keyboard.
The “$” symbol is used to represent the dollar.
