Re: Delphi 2005, Error using ADO

Hi,

sounds like some ADO.NET library got corrupted or deleted. Search in your
BDS\3.0\lib directory for Borland.VCL.ADOConst.dcuil,
Borland.VCL.ADOdb.dcuil, Borland.VCL.ADOInt.dcuil and
Borland.VCL.ADONETDb.dcuil. If one of these is missing then you found your
problem.

On the other hand, ADO components are nothing but wrappers around the ADO
components that come with MDAC, which is provided by Microsoft. You could
try to reinstall it. Actual version is 2.8. You can download it from
http://msdn.microsoft.com/data/default.aspx
