TITLE   :PRB: UpDown Control May Not Increment As Expected
PRODUCT :Microsoft Visual Basic for Windows
PROD/VER:WINDOWS:5.0
OPER/SYS:WINDOWS
KEYWORDS:

======================================================================
---------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Visual Basic Learning, Professional, and Enterprise Editions
   for Windows, version 5.0
---------------------------------------------------------------------

SYMPTOMS
========

When you click the up or down button on an UpDown control, you notice that
the value changes by more than the amount specified for the Increment
property. For example, if the Increment property is 2, the value of the
UpDown control may change by 3 instead of 2.

CAUSE
=====

When you click the up or down button to change the value of an UpDown
control, the control will first "normalize" the current value before it is
changed by the amount specified in the Increment property. By normalizing
the value, the UpDown control may change by more than the amount specified
in the Increment property so that the new value is evenly divisible by the
Increment.

STATUS
======

This behavior is by design.

Steps to Reproduce Behavior
---------------------------

1. Start a new Standard EXE project. Form1 is created by default.

2. Choose Components from the Project menu, check "Microsoft Windows
   Common Controls-2" and click OK. The UpDown control should now be
   available on the Toolbox.

3. Add a Textbox control to Form1.

4. Add an UpDown control to Form1.

5. Set the properties of the UpDown1 control as follows:

      BuddyControl = Text1
      BuddyProperty = Text
      Increment = 2
      Max = 13
      Min = 3
      Value = 3

6. Add the following code to the Form1 module:

      Option Explicit

      Private Sub Form_Load()
         Text1.Text = UpDown1.Min
      End Sub

7. Run the project. Form1 appears.

8. Click once on the up arrow of the UpDown control. Although the Increment
   property is 2, the value of the UpDown control changes from 3 to 6
   rather than 3 to 5.
