Question

I’m working on a project that shows a menu in a game. But to open up the menu you have to press the Insert key. I found 2 ways to do that but they both give me errors. Here’s the code:

      Dim insert As Boolean = GetAsyncKeyState(Keys.Insert)

or

     GetAsyncKeyState(118)

The error I’m getting is PInvoke restriction: cannot return variants

I’m not very familiar with this stuff so please help, How do I make it so I can press the insert key?

If this is WinForms, set the form’s KeyPreview to true and override the OnKeyDown method:

Public Class Form1

  Public Sub New()
    InitializeComponent()
    Me.KeyPreview = True
  End Sub

  Protected Overrides Sub OnKeyDown(ByVal e As System.Windows.Forms.KeyEventArgs)
    If e.KeyCode = Keys.Insert Then
      MessageBox.Show("I'm inserting!")
    End If
  End Sub

End Class
