Q171471: FIX: VB-Created Controls Fail to Print w/UserControl_Paint

Article: Q171471
Product(s): Microsoft Visual Basic for Windows
Version(s): 5.0
Operating System(s): 
Keyword(s): kbVBp500 kbVS97sp2fix kbGrpDSVB kbvbp500sp2fix

-------------------------------------------------------------------------------
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
========

When printing forms, drawings within UserControls will not be printed. The
problem occurs when you print forms from the Visual Basic 5.0 IDE using either
the Print command on the File menu or the PrintForm method at run- time. The
problem does not occur when the project is made into an EXE.

CAUSE
=====

When a UserControl contains drawing methods within its Paint event, this event
is not triggered in the IDE in the same way as it is when the UserControl is
within a compiled application. The IDE disables this event when its Print
functionality is used. This same behavior is apparent in Run Mode when using the
PrintForm method.

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 Studio 97 Service
Pack 2.

For more information on the Visual Studio 97 Service Pack 2, please see the
following article in the Microsoft Knowledge Base:

MORE INFORMATION

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

1. Create a standard EXE project.

2. Add a UserControl to this project.

3. Add the following code to the UserControl code window:

        Private Sub UserControl_Paint()
           Dim r As Single
           Dim smidX As Single
           Dim smidY As Single

           UserControl.DrawWidth = 3
           smidX = ScaleWidth / 2
           smidY = ScaleHeight / 2
           Do While smidX - r > 0
              Circle (smidX, smidY), r
              r = r + 200
           Loop
        End Sub

4. Close the code window and the UserControl designer.

5. Add an instance of the control to Form1.

6. Click Print from the File menu. Select the Form Image option. Note that the
  graphics painted in the UserControl_Paint event do not appear on the printed
  output.
