ID: Q148445
|
The information in this article applies to:
-
Microsoft Access versions 7.0, 97
IMPORTANT: This article contains information about editing the registry.
Before you edit the registry, you should first make a backup copy of the
registry files (System.dat and User.dat). Both are hidden files in the
Windows folder.
SYMPTOMS
Advanced: Requires expert coding, interoperability, and multiuser skills.
When you open a Microsoft Access version 2.0 database for the first time in
Microsoft Access version 7.0 or 97 without converting the database to the later version, you may receive the following error messages:
Out of Memory
I/O Device Error
CAUSE
The Microsoft Jet database engine version 2.x ISAM is out of buffer space.
This can occur when the Microsoft Access version 2.0 database contains many
form modules and/or report modules.
RESOLUTION
Increase the number of buffers available to the Microsoft Jet database
engine version 2.x ISAM by setting the MaxBufferSize parameter in the
Windows Registry.
WARNING: Using Registry Editor incorrectly can cause serious problems that
may require you to reinstall Windows 95. Microsoft cannot guarantee that
problems resulting from the incorrect use of Registry Editor can be solved.
Use Registry Editor at your own risk.
For information about how to edit the registry, view the Changing Keys And
Values Help topic in Registry Editor (Regedit.exe). Note that you
should make a backup copy of the registry files (System.dat and User.dat)
before you edit the registry.
To set the MaxBufferSize parameter in Microsoft Access 7.0, follow these
steps:
- Start the Registry Editor and navigate to the following key:
\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\3.0\Engines\Jet 2.x
- Using the right mouse button (right-click), click the "Jet 2.x"
key, point to New, and then click Key.
- Type the following name for the new key:
ISAM
- Right-click the "ISAM" key, point to New, and then click DWORD.

MaxBufferSize
- Right-click the "MaxBufferSize" DWORD, and then click Modify.
- In the Edit DWORD Value box, click the Decimal base option.
- In the Value Data box, enter 1024, and then click OK.
NOTE: If your Microsoft Access version 2.0 database is very large,
you may want to use a higher value, such as 2048. The maximum value
is 4096 using the Decimal base option (or 1000 Hexadecimal).
- Quit the Registry Editor.
- Start Microsoft Access 7.0 and open the Microsoft Access 2.0 database
(without converting it). The database should open without error.
To set the MaxBufferSize parameter in Microsoft Access 97, follow these

then click Modify.

you may want to use a higher value, such as 2048. The maximum value
is 4096 using the Decimal base option (or 1000 Hexadecimal).
- Quit the Registry Editor.
