Hello Abdelkader Souarit, >hi; i want to try Disqlite pro version but i cant compil it under delphi2009. >i have this error : Your Delphi reports that it can not find TDISQLite3BlobHandle. This identifier is defined in DISQLite3 Pro, but not in DISQLite3 Personal. From this I conclude that your tries to link DISQLite3Database.pas from DISQLite3 Pro with DISQLite3Api.dcu from DISQLite3 Personal. Possible reason: * Your Delphi search path points to DISQLite3Api.dcu from DISQLite3 Personal, possibly because you extracted the two packages into different directories and you did not adjust your search paths accordingly. Suggested solution: * Remove DISQLite3Api.dcu (Personal) from your Delphi search path. There are multiple ways to do this, but the most reliable is to delete all your DISQLite3 files from disk (both Personal and Pro) and then re-extract the DISQLite3 Pro package files.
