SYMPTOMS

A Visual Basic project crashes with an Invalid Page Fault (IPF) when you try to call the PrintForm method in a form containing a UserControl. This behavior occurs when trying to print to a postscript printer from Microsoft Windows 95 or Microsoft Windows 98. The error message is similar to the following:

This program has performed an illegal operation and will be shutdown.

Clicking on Details may reveal text similar to the following:

VB6 caused a general protection fault in module PSCRIPT.DRV at 0004:00000020.

This problem does not occur on non-postscript printers.

Steps to Reproduce Behavior

Create a new Visual Basic Standard EXE project. Form1 is created by default.
Add a CommandButton control to Form1.
From the File menu, select Add Project to add a new ActiveX Control project to the project group.
Add a PictureBox control to UserControl1 and make sure that the AutoRedraw property of PictureBox1 is set to True.

Paste the following code into the code window of Usercontrol1:

Private Sub UserControl_Initialize()
    Picture1.Line (0, 0)-(2000, 2000)
End Sub

Close the design window of the UserControl and add a UserControl1 to Form1 in Project1.

Paste the following code into Form1's code window:

Private Sub Command1_Click()
    Me.PrintForm
End Sub

Run the project and click the CommandButton. Note that the Invalid Page Fault occurs.
