Product(s): Microsoft Visual Basic for Windows
Version(s): 
Operating System(s): 
Keyword(s): kbGrpDSVB

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

- Microsoft Visual Basic Learning Edition for Windows, version 5.0 
- Microsoft Visual Basic Professional Edition for Windows, version 5.0 
- Microsoft Visual Basic Enterprise Edition 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. This bug has been fixed in Visual Basic 6.0.

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.
