Article ID: Q176438
The information in this article applies to:
  • Microsoft Visual Basic Learning, Professional, and Enterprise Editions for Windows, version 5.0

SYMPTOMS

Loading a GIF file that does not specifically contain an Image Object into Visual Basic (via the PictureBox control for example), generates the run- time error 50003: 

   "Unexpected Error"

RESOLUTION

There are two main workarounds currently available:

  • Trap for and handle appropriately error 50003 (Unexpected error) in your Visual Basic application.

    -or-

  • Ensure that images contained within a GIF file are included specifically as Image Objects and not contained within Application Blocks.

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

Visual Basic 5.0 does not currently support GIFs that include images which are contained within Application Blocks. The Image Object must be included in the GIF as a separate Image Object. This functionality does currently exist in Microsoft Internet Explorer 4.0.
