Q165768: FIX: Treeview Control ItemTips Fail on Windows NT 4.0

Article: Q165768
Product(s): Microsoft FoxPro
Version(s): 5.0 5.0a
Operating System(s): 
Keyword(s): kbinterop kbvfp500aBUG kbvfp500bugkbbuglist

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

- Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you install the Treeview control with Microsoft applications or development
tools released after January 1, 1997, it does not show ItemTips correctly when
the control is on a form running on Windows NT 4.0.

CAUSE
=====

The ItemTips feature of the version of the Treeview control that comes with the
most recent version of Comctl32.ocx is incompatible with Windows NT version 4.0
Workstation and 4.0 Server.

The other features of the control operate as expected, and the ItemTips feature
works when the Visual FoxPro form resides on Windows 95.

NOTE: This behavior does not occur if you use Comctl32.ocx version 1.0.2908 that
is shipped with Visual FoxPro 5.0.

RESOLUTION
==========

If the Visual FoxPro for Windows application must have ItemTips the developer
can remove the version of the control that is on the system and replace it with
the version that came on the Visual FoxPro version 5.0 CD-ROM.

This probably will be unsatisfactory if you need to distribute the application to
users running on Windows NT 4.0 who also have installed other applications that
accompanied the newer version of the Comctl32.ocx. On those systems the Setup
program will not replace the later version of the control with the one
distributed with the Visual FoxPro application.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. This has been corrected in Visual FoxPro 6.0.

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

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

1. Install Visual FoxPro 5.0 on a system using Windows NT 4.0.

2. Install Visual Basic 5.0, Visual C++ 5.0, Office 97, or any other Microsoft
  product that installs the most recent version of Comctll32.ocx.

3. Create a new form in Visual FoxPro 5.0.

4. Place the OLE Container Control on the form.

5. In the Insert Object dialog box, click Insert Control.

6. Select the Microsoft Treeview Control from the list.

7. Add the following to the Init Event method of the form or the Treeview
  control:

        Thisform.OLEControl1.Nodes.add(,,,"This is a long string of text")

8. Run the form and put the mouse cursor over the item in the Treeview.

When you perform steps 2 through 7 in a Windows 95 system, the text of the string
appears as an ItemTip. If the string is longer than the space in the Treeview,
the entire string shows even though it is wider than the control.
