BUG: Resource Manager Error When Printing Lots of Fonts

ID: Q108717

The information in this article applies to:

Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0, 5.0a, 6.0
Microsoft FoxPro for Windows, versions 2.5x, 2.6x

SYMPTOMS

When FoxPro is printing a large number of fonts under Windows 3.x (16-bit Windows), FoxPro displays the following error message:

Resource Manager Internal Consistency Error

Additionally, Visual FoxPro then displays the following error message:

Win32s - Error Unhandled Exception detected. Application will be terminated.

NOTE: Visual FoxPro 3.0b for Windows prints a much greater number of fonts than Visual FoxPro 3.0 for Windows does before displaying the error message.

CAUSE

FoxPro is not properly releasing graphics device interface (GDI) resources under Windows.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
