[TuT] Trigger a Button With a Key - Black Ghost - 06-29-2011

1. Make a new application.
2. Double click anywhere on your program so you get to the code.
3. Now there should be a drop down menu in the top right corner, select "Key_Down" from that menu.
4. Now place this code there:

Code:
If e.Keys = KeyCode.Enter Then

Button1.Perform_Click

End if

You can change "Button1" to whatever your button is named as.

Enjoy Smile

Yes, that's why you have your account Closed.

It's not:

Code:
Button1.Perform_Click

It is:

Code:
Button1.PerformClick()

Also, you forgot to mention that the value needs to be:

Code:
System.Windows.Forms.KeyEventArgs

And not the usual:

Code:
System.EventArgs

Otherwise it won't work.

And also, it should be KeyData instead of KeyCode Otherwise keys in combination with Enter will also activate the button click event. KeyData ensures that it only happens when enter is pressed alone, so that something like {Shift} + {Enter} will not work to activate the button click, whereas if you had KeyCode it will...

You also got the first part of your code mixed up a bit, instead it should be:

Code:
If e.KeyCode = Keys.Enter Then

Not

Code:
If e.Keys = KeyCode.Enter Then

But the preferred code for one keydown event should be this in my opinion:

Code:
If e.KeyData = Keys.Enter Then

    Button1.PerformClick()

End If

Full thing:

Code:
Private Sub Something_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles SomeControl.KeyDown

        If e.KeyData = Keys.A Then

            Button1.PerformClick()

        End If

    End Sub

Take note that ByVal e is System.Windows.Forms.KeyEventArgs. If e was System.EventArgs, which is the default, then it will not work.

An Example of a Multiple Keydown event would be:

Code:
If e.Control = True AndAlso e.Alt AndAlso e.KeyCode = Keys.T Then

    Button1.PerformClick()

End If

That will work when the Ctrl, Alt and "T" key on the keyboard are pressed in combination.
