SYMPTOMS
========

The Click event of a Sheridan command button fires when it attempts to retrieve
the WhatsThisHelp property on the button. The Click event should not be raised
when WhatsThisMode is active.

RESOLUTION
==========

The MouseDown event of the Sheridan command button does not fire when a Form is
in WhatThisMode. To work around the problem, set a flag when the MouseDown event
of the command button does fire. Check the flag in the Click event of the button
to determine if code needs to be run.

MORE INFORMATION
================

This problem has been reproduced with version 1.0.41.0 of the Sheridan 3D
Controls library (Threed32.ocx).

Steps to Reproduce and Work Around the Behavior
-----------------------------------------------

1. Create a new Standard EXE project in Visual Basic. Form1 is created by
  default.

2. In the Properties window, set the MaxButton and MinButton properties of Form1
  to False.

3. In the Properties Window, set the WhatsThisButton property of Form1 to True.

4. On the Project menu, click to select Components, select Sheridan 3D Controls,
  and then click OK.

5. Add an SSCommand control to Form1.

6. Paste the following code into the code window of Form1:

  Dim blnFireEvent As Boolean

  Private Sub Form_Load()
      blnFireEvent = False
  End Sub

  Private Sub SSCommand1_Click()
      If blnFireEvent Then
          MsgBox "Execute the click event code"
          blnFireEvent = False
      Else
          MsgBox "WhatsThisMode is active"
      End If
  End Sub

  Private Sub SSCommand1_KeyDown(KeyCode As Integer, Shift As Integer)
      ' The keyboard was used on the button.
      ' Set the flag to execute the code.
      blnFireEvent = True
  End Sub

  Private Sub SSCommand1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
      ' Because the MouseDown event was raised, WhatsThisHelp is not active.
      ' Set the flag to execute the code.
      blnFireEvent = True
  End Sub

7. Run the project. Click SSCommand1, and note that a message box is displayed
  indicating that you should execute the click event code.

8. Dismiss the message box.

9. Enter WhatsThisMode by clicking on the WhatsThisHelp button at the top right
  of Form1.

10. Click SSCommand1, and note that a message box is displayed indicating that
  you are in WhatsThisMode.
