TITLE   :BUG: Scale Method Results in a Number of Blank Pages Printed
PRODUCT :Microsoft Visual Basic for Windows
PROD/VER:WINDOWS:5.0
OPER/SYS:WINDOWS
KEYWORDS:VBKBPrinting

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

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

SYMPTOMS
========

The Scale method of the Printer object prints a number of blank pages when
the Scale values are set so that the first Y-coordinate value is greater
than the second Y-coordinate value.

RESOLUTION
==========

To work around this bug, set Y-coordinate values in the Scale method so the
first Y-coordinate is less than the second Y-coordinate.

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
================

This section shows you how to reproduce this bug.

NOTE: Set your default printer to print to a file if you want to reproduce
this bug. Sending the output to a printer may result in many blank pages.

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

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


2. Add two CommandButtons to Form1.

3. Copy the following code to the Code window of Form1:

      Option Explicit

      Dim intCounter As Integer

      Private Sub Form_Load()
         Command1.Caption = "Demonstrate the Problem"
         Command2.Caption = "Demonstrate the Expected Behavior"
      End Sub

      Private Sub Command1_Click()
      'This button demonstrates the problem.

         Printer.Scale (0, 250)-(140, 0)  'Y-Coordinate is descending
         Printer.Print " "

         For intCounter = 1 To 100
            Printer.Print "Item #" & intCounter
         Next intCounter

         MsgBox "# Pages : " & Printer.Page

         Printer.EndDoc

      End Sub

      Private Sub Command2_Click()
      'This button demonstrates the expected behavior

         Printer.Scale (0, 0)-(140, 250)  'Y-Coordinate is ascending
         Printer.Print " "

         For intCounter = 1 To 100
            Printer.Print "Item #" & intCounter
         Next intCounter

         MsgBox "# Pages : " & Printer.Page

         Printer.EndDoc

      End Sub

4. Press the F5 key to run the program. Click Expected Behavior to
   determine how many pages are printed. Click Bug Behavior and note that
   the number of pages printed exceed that of the Expected Behavior button.
