The application was working perfectly, until I edited the user database (*.dbf) in OpenOffice.org Calc.

BDE administrator net dir

I am learning BDE adminstrator and I was wondering if there was a way to write a script/command(that i can run by double clicking) to add the net dir to a certain directory path ? I looked through the windows registry editor, and tried to find the net dir but it was not there. The NET DIR setting is stored in the BDS configuration file. This file, by default, is named IDAPI.CFG and is stored in %PROGRAMFILES%\Borland\Borland Shared\BDE\IDAPI.CFG . It can be changed to a different name and location by changing the registry at HKEY_LOCAL_MACHINE/Software/Borland/Database Engine/CONFIGFILE01 .

BDE, Windows 7 and UAC

I have a very old application written in delphi 5 running in some customers which uses the BDE. Now some users with Windows Vista and 7, had experimented some problems with the multiuser access. i' think which these problems are related to the location of the net .and .lck files. so the question is which is the proper way to confgure the BDE under Windows Vista and 7 to avoid permissions and UAC conflicts? In addition to the above answer, you'll want to make sure that the .net and .lck files are located in a user-specific directory under Windows 7, specifically: C:\Users\{User Name}\AppData

How does Paradox manage null and empty values?

由 青春壹個敷衍的年華 提交于 2019-12-02 09:56:05
问题 I'm using Paradox tables through Borland Database Engine (BDE). I'm not able to realise the way null and empty string values are handled in string fields (Paradox data type "A"). My specific problem is how to determine if a field value is null or empty string. In Database Desktop tool they all seem to be empty strings. I need this because I'm migrating data (with Database Desktop and also programmatically) to a Firebird DB and the field values which seem to be empty strings are all copied to

BDE initialization failure (error $2501) on Vista

I have a small datasnap server written in Delphi 2007 that accesses the BDE. It works fine on Windows 2000 and XP but from time to time (actually quite regularly) on Vista I get the error message: An error occurred while attempting to initialize the Borland Database Engine (error $2501) Closing everything down that uses the BDE fixes the error (although you sometimes need to "End Process" the datasnap server to close it). This is becoming rather annoying as more and more of our clients are running Vista for their "server". Does anyone have any suggestions? You haven't mentioned if you've tried
