-------------------------------------------------------------------------------

SYMPTOMS
========

When an UpDown control's BuddyControl property is set to an intrinsic control,
the BuddyProperty returns an empty string in a compiled EXE.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.

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

The BuddyProperty sets or returns the property used to synchronize the UpDown
control with its buddy control. When the buddy control is a Visual Basic
intrinsic control, the BuddyPropery returns a blank string in a compiled exe.
The BuddyProperty works correctly in the IDE for intrinsic controls. It also
returns the correct value in an EXE or the IDE if the BuddyControl property is
set to an ActiveX control.

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

1. Create a new standard EXE project. Form1 is created by default.

2. From the Project menu, select Components, check both "Microsoft Windows
  Common Controls" and "Microsoft Windows Common Controls-2," And then click
  OK.

3. Add two UpDown controls, a TextBox, a Slider, and a CommandButton to Form1.

4. Add the following code to the module of Form1:

        Private Sub Command1_Click()
          MsgBox "Updown1 BuddyPropery is " & UpDown1.BuddyProperty
          MsgBox "Updown2 BuddyPropery is " & UpDown2.BuddyProperty
        End Sub

        Private Sub Form_Load()
          UpDown1.BuddyControl = Text1
          UpDown1.BuddyProperty = "text"
          UpDown2.BuddyControl = Slider1
          UpDown2.BuddyProperty = "value"
        End Sub

5. From the File menu, Save the project and Make an EXE.

6. Run the project in the Visual Basic IDE and click on Command1, and note that
  the BuddyProperty returns the correct value for both Text1 and Slider1.

7. Run the compiled EXE from Windows Explorer and click on Command1. Note that
  the BuddyPropery only returns the correct value for Slider1 and not for
  Text1.
