 * }

Q96893

-

The information in this article applies to:


 * Microsoft Access 1.0

-

SYMPTOMS
Microsoft Access will produce a general protection (GP) fault if the OLEDATA property is set to a null value or an invalid object.

CAUSE
OLEDATA is a property of an unbound embedded object used in either a form or report. The property is not available in the Object Properties dialog box; it is set by Microsoft Access and can only be modified using Access Basic code.

If the OLEDATA property is set to an invalid object, Microsoft Access will display the error &quot;Not a valid OLE object.&quot; Microsoft Access will allow you to exit the dialog box and continue to work in design mode. The frame will remain in the form or report; however, since its link is broken, it will be dimmed. Access will produce a GP fault when leaving design mode to display the form in view mode, or the report in print preview mode.

If the OLEDATA property is set to null, Microsoft Access will display the error &quot;The setting you entered isn't valid for this property&quot; and produce a GP fault upon exiting the dialog box.

RESOLUTION
Setting the embedded objects Visible property to False will suppress the display of the object.

STATUS
Microsoft has confirmed this to be a problem in Microsoft Access version 1.0. This problem was corrected in Microsoft Access version 1.1.

MORE INFORMATION
Any unbound embedded object inserted with the Paste, Paste Link*, or Paste Special* command is subject to the GP fault if the OLEDATA property is set to a invalid object.

Steps to Reproduce Problem
 Using Paintbrush, open any .BMP file. Select the object and copy it to the Clipboard. Exit Paintbrush. Open Microsoft Access and create a new database. Create a new form. In the form's Design view, paste in the object. Leave the form open and go to the Database window. Create a new module.</li> Open the Immediate window.

OPTION 1:</li>  Enter the following command:

Forms![Form1]![Embedded0].OLEDATA=NULL

Microsoft Access will display the following error:

The setting you entered isn't valid for this property.

</li> Choose the OK button. Microsoft Access will cause a GP fault.

OPTION 2:</li>  Enter the following command:

Forms![Form1]![Embedded0].OLEDATA=&quot;X&quot;

Microsoft Access will display the following error:

Not a valid OLE object

</li> Choose the OK button.</li> Go back to Form1.</li> Switch to the form's View window. Microsoft Access will cause a GP fault.</li></ol>
