MORE INFORMATION
IMPORTANT: This article contains information about modifying the registry.

Steps to Reproduce Behavior
- Make a copy of the Order Details table in the sample database Northwind.mdb. Be sure to copy structure and data. Name the new table Order Details Copy. Remove the primary key from the table to allow the append query to run successfully. There are 2,155 records in the Order Details table in the original Northwind.mdb file.
- Create an append query and run it two times to append a total of 4,310 records to Order Details Copy table. At this point there should be a total of 6,465 records in the new table.
- WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
NOTE: Before you complete the next step, make a note of the current value in the MaxLocksPerFile key before you change the value so that you can restore the initial value at the end of these steps.
Set the value in the following registry keyHKEY_LOCAL_MACHINE\Software\Microsoft\Jet\4.0\Engines\Jet 4.0\MaxLocksPerFile
to a decimal value of 5,000.
IMPORTANT: You must restart Microsoft Access after making this change.
- Open the Order Details Copy table in Datasheet view, hold down the CTRL key and press the A key to select all the records, and then click Delete.
The behavior described in this article occurs only when you see the "You won't be able to undo this delete operation" warning. When prompted with this warning, click Yes. - You are prompted with the following message:
Do you want to suppress further error messages.
Click either Yes or No; it won't change the results.
With these actions, you would expect all records to be deleted from the table. When the delete operation is completed, however, the table still has one or more records remaining. As you lower the value for MaxLocksPerFile, the number of records remaining in the table is increased.
- Set the value in the following registry key
back to the value that you noted in step 3.
HKEY_LOCAL_MACHINE\Software\Microsoft\Jet\4.0\Engines\Jet 4.0\MaxLocksPerFile
Additional query words: pra remain remains CTRL+A not all removed gone still isn t you won be able to undo this delete operation remove left
