Build 174

USE now reports a "file is in use" error when the file is open exclusively somewhere else. VARCHAR and VARBINARY fields are handled correctly.

Build 173

Added read support for all data types supported in Microsoft Visual FoxPro™ 9.0 DBF files. There are some differences, though:

• GENERAL fields are treated as plain memo fields. Support for GENERAL fields has currently low priority as it's a seldom used feature and difficult to implement. On the other hand it has got the advantage that you can use Guineu to extract data from a General field.
  
• VARBINARY and VARCHAR fields currently do not trim content. This will change soon.
  
• Some parts of the code page conversion do not yet work properly. If the table has got the same code page as the user's computer, there shouldn't be any problem.
