Enter Key and a Listbox

Enter Key and a Listbox

• MarkBosley

  You may want to trap for the return key also ...they have two different key codes...so this should work no matter if you press enter or return:

  Private Sub ListBox1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles ListBox1.KeyUp

  If e.KeyCode = Keys.Enter Or e.KeyCode = Keys.Return Then

  Button1.PerformClick()

  End If

  End Sub

  have you implemented the listboxs' keydown event, and used the code you supplied there

  What happens when "it doesnt work"

  the problem seems to be the "Handles" part of the code.

  it should not be "Me.KeyDown" but "EmployeeList.KeyDown", without the quotes.

  Yes I have put it in both ,key up and key down,both are present

  Private Sub EmployeeList_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown

  If e.KeyCode = Keys.Enter Then

  MsgBox("HA")

  Button2.PerformClick()

  End If

  End Sub

  Private Sub EmployeeList_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyUp

  If e.KeyCode = Keys.Enter Then

  MsgBox("HA HA")

  Button2.PerformClick()

  End If

  End Sub

  Nothing happens - I put a msgbox in both of them and no msgbox

  When I changed it to

  Private Sub EmployeeList_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles EmployeeList.KeyDown

  If e.KeyCode = Keys.Enter Then

  MsgBox("HA")

  Button2.PerformClick()

  End If

  End Sub

  I got an error with the Key.Down at the end of the statement being

  Handles clause requires a WithEvent variable defined in the containing type or one of its base types

  How do I correct this

  the best thing to do David, is to go into the form designer, click on the control and in the properties window, select the events icon (lightning symbol) and double click the KeyDown event to create the proper event handler, if you have not done so already.

  thats what I did the first time when it gave the Me.KeyDown.
