Keyboard capture with ProcessCmdKey

[flynn]

Is it not possible to capture every CONTROL-x keyboard combination, where "x" is any alphabetic character?

 

Using the following code, I can't seem to capture CTRL-J, but CTRL-F works.

 

Protected Overrides Function ProcessCmdKey(ByRef msg As System.Windows.Forms.Message, ByVal keyData As System.Windows.Forms.Keys) As Boolean

       If (keyData = (Keys.Control Or Keys.J)) Then
           Console.WriteLine("You pressed CTRL+J")
           Return (True)
       End If

       If (keyData = (Keys.Control Or Keys.F)) Then
           Console.WriteLine("You pressed CTRL+F")
           Return (True)
       End If

       Return MyBase.ProcessCmdKey(msg, keyData)

End Function

There should be no difference between catching Crtl+F or a Ctrl+J; both worked on this pc in fact.

 

Is there some other application running that has already installed a hook for the Ctrl+J combination?
