MessageBox.Show not raising HelpRequested event

- by Trevortni

I have a form that is showing a MessageBox using MessageBox.Show, and trying to receive events from the Help button on the MessageBox so I can execute my own code. The Microsoft documentation shows how to do this; however, using what is suggested does not work. Here's a shortened version of my code: Private Function MethodName() As Boolean AddHandler Me.HelpRequested, AddressOf Me.MsgBoxHelpRequested Select Case MessageBox.Show("Text", "Title", MessageButtons.YesNoCancel, MessageBoxIcon.Question, MessageBoxDefaultButton.Button2, 0, True) Case MsgBoxResult.Yes ' Do stuff Case MsgBoxResult.No ' Do stuff Case MsgBoxResult.Cancel RemoveHandler Me.HelpRequested, AddressOf Me.MsgBoxHelpRequested Return False End Select RemoveHandler Me.HelpRequested, AddressOf Me.MsgBoxHelpRequested End Function Private Sub MsgBoxHelpRequested(ByVal sender As Object, ByVal hlpevent As System.Windows.Forms.HelpEventArgs) ' Breakpoint that never gets hit ' More code End Sub I've been searching for a solution to this problem, but the best I've found is this question: http://stackoverflow.com/questions/2407880/how-to-detect-help-button-press-in-windows-forms-messagebox that refers me back to the same Microsoft code that doesn't seem to be working. Can anybody help me with this? Thank you.
