It is not possible to copy only BDE files, but also to write the registry:
The required registry entries include:
1.BDE Dynamic Connection library file location settings
Key: "Hkey_local_machine\software\borland\database Engine"
Item: "DllPath"
Value:bde the location of the dynamic connection library file, such as "C:\Program Files\borland\common Files\bde"
(open "C:\Program files\borland\common files\bde\bde32.hlp",
Find "Core files" to understand the role of BDE Dynamic Connection library files
2.BDE Language driver file path settings
Key: "Hkey_local_machine\software\borland\blw32"
Item: "Blapipath"
The path where the Value:bde language driver file is located, such as "C:\Program Files\borland\common Files\bde"
(BDE language drivers are those *. BLL file)
3. Specify the available BDE language driver files
Key: "Hkey_local_machine\software\borland\blw32"
Item: "locale_lib#" (#表示数字, such as "LOCALE_LIB1", "locale_lib3", etc.)
Value: Specifies each BDE language driver file, such as "C:\Program Files\borland\common Files\bde\usa." BLL "
(Generally required language driver files are "USA.") BLL "," EUROPE. BLL "and" FAREAST. BLL ", for the sake of insurance, it is recommended that all language drivers be set up. On the machine with the DELPHI3 installed, open the registry with Regedit, and you will see how it is set up.
