问题描述
应用程序运行正常，直到在OpenOffice.org Calc中编辑用户数据库（* .dbf）。现在它给出了关于封闭数据集的上述错误。
The application was working perfectly, until I edited the user database (*.dbf) in OpenOffice.org Calc. Now it gives me the above error about a closed dataset.
推荐答案
根据您自己的评论，您无法打开数据库文件因为它已损坏。因此，您的案例中的错误意味着您不会忘记打开它，但是您的应用程序无法打开损坏的.dbf文件。
As per your own comment, you were unable to open the database file because it was corrupt. Thus, the error in your case meant not that you forgot to open it, but that your app cannot open the corrupt .dbf file.
其他不太明显的原因为什么您可能会收到此错误，而不是您将Active属性设置为true的显而易见的事情，包括系统或BDE配置错误（ODBC或ADO或其他缺少或未配置的BDE运行时文件），以便打开档案
Other not-so-obvious reasons why you might get this error, than the obvious thing that you failed to set the table Active property to true, include system or BDE configuration errors (ODBC or ADO, or other BDE runtime files missing or not configured) that are required to open the file
