This article was previously published under Q171547 SYMPTOMS
When a Visual Basic 5.0 application using the DBGrid32.ocx is installed on
a machine that previously had a Visual Basic 4.0 application installed and
was also using its version of the DbGrid32.ocx, an untrappable run-time
error (-1)(ffffffff) may result when editing a cell within the Visual Basic
4.0 application. This behavior should not occur because the new DBGrid
should be backwards-compatible.
You receive the following error messages:
Runtime Error -1, (ffffffff)
when you expect no error.
CAUSE
This problem is caused by a bug in the Visual Basic 5.0 Data Bound Grid
Controls (DBGrid32.ocx) in the version that ships with the product
(5.00.3714) and in the version that ships with Visual Studio 97 Service
Pack 1 (5.00.3817). Visual Studio 97 Service Pack 2 did not include an
updated version of the control.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article. This bug has been fixed in Visual Studio
97 Service Pack 3.

MORE INFORMATION
This problem does not occur if the application that uses the DBGrid control
has been built with Visual Basic 5.0.
This problem does not occur if the application built by Visual Basic 4.0 is
a 16-bit application. That application would use the 16-bit DBGrid control
and would be unaffected by this problem in the 32-bit version of the
control.
