INSERT, UPDATE and DELETE Records Are Lost On Reset (308250)

SYMPTOMS

When you are using ADOCE to manage a database, INSERT, UPDATE, and DELETE records may be lost. This symptom may occur if the Windows CE device is reset before the database connection object is closed.

CAUSE

ADOCE opens a database as a mounted object, and caches all writes to the database object until the object is closed. Resetting the device does not give the operating system the opportunity to write the cached data to real storage, so all of the changes to the database are lost.

RESOLUTION

A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next release of ADOCE for your platform that contains this hotfix.

WORKAROUND

Close the recordset and connection object after INSERT, UPDATE, or DELETE operations have been performed. This forces a write of the cached database to real storage.
