Access 97/BDE 4.51 and 5.01/NT SP4 and 5 EEFFACE error solution


This is for anyone who gets an EEFFACE exception under NT 4 SP 4 or 5 when
accessing an MS Access memo or long binary field with the BDE 4.51 or 5.01.

The solution is to modify the registry.

1 go to the key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\Currentversion\Image file
execution options

2 Add a key for your application, f.i: myapp.exe

3 Add a value to the newly created key:

Value name: DisableHeapLookAside
Data type:     REG_SZ
String:           "1" (without quotes)

Start myapp.exe again and the problems dissapear.
