The stand-alone version of 4D 6.5 includes the ability to perform a diagnostic check of the structure file when you open a database. When you start 4D 6.5, you are presented with the "Open Database" dialog:



If you use the option to "Open an Existing Database," you can select a database from the dialog's list of your most recently accessed databases. After highlighting the name of one of the databases in the list, you can click the "Options..." button. This opens a new dialog that displays the path to the structure file and data file to be opened:



You can click the "Other..." button in this dialog to select a different data file to open with the structure, or you can click the "New..." button to create a new data file for this structure.

If you check the "Check the Structure File" checkbox, then click the "Open" button, 4D will perform a diagnostic check of your structure.

Alternately, from the main "Open Database" dialog, you can click the "Other..." button to display a dialog from which you can open a database that isn't in the list of recently used databases. From that dialog, you can activate the structure checking feature by holding down the Ctrl and Alt keys (Windows) or the Control and Command keys (Macintosh) while clicking that dialog's Open button.



When the tests are completed, the results are displayed:



Objects that are tested to see if they are correct or damaged include:

• Resource Map
