SYMPTOMS
When you use Accusoft's Image Format Library .OCX with Visual FoxPro and
attempt to register added controls, you receive this error:
The file does not appear to be a valid OLE control
After you clear the first error message, you may receive this additional
error message:
Unable to register the OLE control.
Using this .OCX control in Microsoft Visual C++ or Microsoft Access works
fine.
Accusoft's Image Control Library .OCX is manufactured by Accusoft, a vendor
independent of Microsoft; we make no warranty, implied or otherwise,
regarding this product's performance or reliability.
CAUSE
Accusoft's Image Control Library .OCX is a 16-bit .OCX rather than a 32-bit
OCX. Accusoft has also released a 32-bit version of this library. For more
information about this control, you can contact Accusoft at (508) 898-2770.
RESOLUTION
There are three requirements for an .OCX to work correctly with Visual
FoxPro:
- The OCX control must be 32-bit.
- A control which supports data binding will not be able to bind to a
Visual FoxPro field or table.
- Visual FoxPro does not support the ISimpleFrameSite interface. Controls
which use this interface may have limited functionality within Visual
FoxPro.
STATUS
This behavior is by design.
