Permissions on DBISAM Files |

Gordon Turner | I'm using Delphi 7 and DBISAM 3.30. All of a sudden (without any
updates to the application) I have several users receiving messages that they are opening data files as Read-Only. User have full access rights to the folder and to the files in the folder. Here is the code I'm using (which has been running fine for years)... with TDBISAMTable(Components[i]) do begin sStopWords := TextIndexStopWords; CheckDBIndexes(DBPath, TableName); Exclusive:=False; ReadOnly:=False; Open; if ReadOnly = True then begin MessageDlgCtr('You do not have the proper access to the TimeOff' + ' data files located in ' + ExcludeTrailingBackslash(DBPath) + '. You need a' + ' minimum of Modify, Read, and Write access to this' + ' folder. Please check with your IT department to make' + ' sure you have the proper privileges.' + MsgCrLf + 'TimeOff will now close.', mtWarning, [mbOK], 0); ... end; ... end; I am at a loss to explain why the users suddenly can no longer open data files. I've tried having them create a brand new data folder manually and then letting the app re-create the files in the new folder, but it fails after trying to create the first .DAT file. I've tried creating a folder locally (C:\Data) and on a file share with the same result. I've tried letting the app create the data folder with the same result. I had one user send me a copy of the data files and I had no problem opening them on my workstation. As best I know, users are running XP - SP3. Any help would be greatly appreciated. |

Gordon Turner | Just to add on, the problem is spreading rapidly - from 3 customers
yesterday to 5 more today. |

With that spread it sounds like an AV update. Do they all run the same anti virus software? Roy Lambert [Team Elevate] |

However (interestingly enough) I have been using Armadillo (currently called Software Passport I believe) as a part of my copy protection scheme (this version of the program was released in October of 2009) and removing the Armadillo wrapper seems to have resolved the problem. |

Preventing them updating the data is pretty good protection Roy Lambert [Team Elevate] |
