Private Sub Command1_LostFocus Debug.Print "Command LF" End Sub

Private Sub UserControl_EnterFocus Debug.Print "ENTERFOCUS" End Sub

Private Sub UserControl_ExitFocus Debug.Print "EXITFOCUS" End Sub  Add a PropertyPage to the project. Insert an instance of the UserControl onto the PropertyPage.</li> Insert a CommandButton onto the PropertyPage.</li>  Add the following code to the PropertyPage's code window: Private Sub Command1_GotFocus Debug.Print "Command1 on property page GF" End Sub

Private Sub Command1_LostFocus Debug.Print "Command1 on property page LF" End Sub </li> In the UserControl's property browser, set the PropertyPage to PropertyPage1.</li> Insert an instance of the UserControl on Form1.</li> Right-click on the UserControl. Click Properties.</li> Click on the CommandButton.

RESULT: NO EVENTS fire off, the Usercontrol's CommandButton should have gotten its LostFocus, the Usercontrol should have gotten its ExitFocus and the CommandButton should have gotten its GotFocus event.</li></ol>
