John | I have an existing table in version 3.0 format that contains a blob field which contains a compressed pdf file. How do I extract that pdf from the blob field into a readable pdf file?
Thanks |

Something like TMemoField(FilAttMgr.FieldByName('_Item')).SaveToFile(PutTo); will save it to disk and ShellExecute(Application.Handle, nil, Pchar(#34 + PutTo + #34), nil, nil, SW_SHOWNORMAL); will display it. Roy Lambert |
