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

- The Resource Editor, included with:
   - Microsoft Visual C++, 32-bit Editions, versions 4.0, 4.1 
   - Microsoft Visual C++, 32-bit Enterprise Edition, version 4.2 
   - Microsoft Visual C++, 32-bit Professional Edition, version 4.2 
-------------------------------------------------------------------------------

SYMPTOMS
========

Edit controls that have previously been given the ES_NUMBER style do not have
the corresponding Number check box selected under the style properties when they
are loaded into the resource editor.

CAUSE
=====

This is a display problem in the resource editor. Although the resouce editor
shows the Number check box as clear, rebuilding the application or opening the
.rc file in text mode will confirm that the ES_NUMBER style is still being
applied to the edit control. However, if the dialog box containing the control
is edited and saved, the ES_NUMBER property will no longer be applied to the
edit control unless you again select the Number check box.

RESOLUTION
==========

Select the Number check box for edit controls that should have the ES_NUMBER
style each time you modify the dialog box containing the edit control.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. This problem was corrected in Microsoft Visual C++,
version 6.0.

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

The ES_NUMBER style first available in Windows 95 restricts input to the edit
control to digits only. If an edit control has this style under Windows NT 3.51,
you can still enter characters other than numbers. However, under Windows 95, an
edit control with this style accepts digits only.
