BUG: DateTimePicker Overrides ALT+F4 Key Combination

MORE INFORMATION

Steps to Reproduce Behavior

1. Create a new Standard EXE project. Form1 is created by default.
2. Choose Components from the Project menu and add a reference to "Microsoft Windows Common Controls-2".
3. Add a DTPicker control to Form1.
4. Add a TextBox Control to Form1.
5. Run the sample application.
6. Put focus on the DTPicker control if it doesn't have focus already.
7. Press the ALT+F4 keys. Note that the form does not close.
8. Move focus to the TextBox.
9. Press the ALT+F4 keys. The form closes as expected.
10. To workaround this behavior, paste the following code into Form1's code window:

           Private Sub DTPicker1_KeyDown(KeyCode As Integer, Shift As Integer)
              ' Check for Alt and F4 keystrokes
              If (Shift And vbAltMask) And (KeyCode = vbKeyF4) Then
                 ' Unload the application
                 Unload Me
              End If
           End Sub
    						

11. Repeat steps 5 - 7 and note that the form closes as expected.
