Q179914: BUG: Terminal Font at 6 Point Size in List Box Grows in Size

Article: Q179914
Product(s): Microsoft FoxPro
Version(s): WINDOWS:2.6,2.6a,3.0,3.0b,5.0,5.0a
Operating System(s):

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

- Microsoft FoxPro for Windows, versions 2.6, 2.6a 
- Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0, 5.0a 
-------------------------------------------------------------------------------

SYMPTOMS
========

When an OEM Terminal font 6 point size is used as the screen font, large amounts
of text displayed in a list box change to a larger font size when a system
window such as Control Panel is opened on top of the FoxPro application window.
The 6 point font size returns when the system is shutdown and restarted but the
font size changes again as soon as a system window is opened.

This behavior occurs when you are running FoxPro for Windows on a computer with
Windows 95. The problem does not occur in FoxPro under the Windows NT operating
system.

RESOLUTION
==========

Do not use the Terminal font or any other screen font for text in a list box.
Either use a TrueType font or upgrade the operating system to Windows NT.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. We are researching this bug and will post new
information here in the Microsoft Knowledge Base as it becomes available.

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

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

FoxPro for Windows versions 2.6, 2.6a
-------------------------------------

1. Start FoxPro for Windows 2.6(a) under the Windows 95 operating system.

2. Use the Customer.dbf table in the FoxPro for Windows TUTORIAL subdirectory.
  The following command opens the table:

        USE HOME()+"Tutorial\Customer"

3. Create a new screen.

4. Add a list box that covers the entire width and height of the new screen. In
  the List dialog box, set the List Items to be From Field. Click the field
  button to open the expression builder. Enter the following expression (or
  similar string to display a large amount of text):

  company+contact+address+city+state+zip+phone+ono+cno

  For the variable for the list, type an x. Click OK to close the List dialog
  box.

5. With the list box selected, click the Font command from the Object menu.
  Select Terminal, regular 6, as the font for the list box.

6. Save the screen and name it Test.spr.

7. In the FoxPro Command window, type the following command:

        DO Test.spr

  The list box should be displaying properly with the Terminal 6 point font.

8. From the Windows 95 Start menu, select Settings and then click Control Panel.

9. Close Control Panel and activate FoxPro.

10. Click an item in the list box. The text changes to a larger, bold font.
  Click an item in the list box and drag the selection up and down the list
  box while the left mouse button is pressed. All the list box items change to
  a larger, bold font.

Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0, 5.0a
--------------------------------------------------------

1. Start Visual FoxPro under the Windows 95 operating system.

2. Type the following code in the FoxPro Command window:

        SET DEFAULT TO HOME()+"SAMPLES\DATA"

3. Create a new program with the following code:

        USE customer SHARED
        DEFINE POPUP getpop ;
           PROMPT FIELD cust_id+company ;
              + contact + address ;
              + city + region ;
              + postalcode + phone ;
              + country + cust_id ;
              SCROLL
        DEFINE WINDOW XXX FROM 1,1 TO 50,100
        ACTIVATE WINDOW XXX

        @ 11,10 GET popit PICTURE "@&N" ;
           POPUP getpop SIZE 30.000,90.667 ;
           DEFAULT " " FONT "Terminal", 6 STYLE ""

        READ CYCLE
        CLEAR ALL
        *** end of program

4. Run the program. The items in the list box display with the correct font
  size.

5. From the Windows 95 Start menu, choose Settings, and then click Control
  Panel.

6. Close Control Panel and activate FoxPro.

7. Click an item in the list box. The text changes to a larger, bold font. Click
  an item in the list box and drag the selection up and down in the list box
  while the left mouse button is pressed. All the list items change to a
  larger, bold font.

NOTE: Duplication of any or all of the behavior described above is unreliable and
random. Since the OEM Terminal screen font does not reside in the Windows 95
operating system but is a font that is subject to Windows 95 font substitution,
the font may be rendered differently on different computer hardware. Testing by
Microsoft has produced three different scenarios on three different computers
without the identification of a factor that would allow control of the
scenario.

The three scenarios are:

- Cannot make the font size change occur under any circumstances.

- The font size change happens before displaying the system window and never
  correctly displays the chosen font.

- The font size change does or does not occur depending upon whether the system
  window is closed or minimized.
