* harbour/ChangeLog
* removed TOVERIFY note - Viktor checked it.
* harbour/contrib/hbct/ctwin.c
! redraw windows after each WCENTER() call
* harbour/contrib/rddads/ads1.c
+ added support for ADS_VARCHAR_FOX and ADS_VARBINARY_FOX fields
in ADS_VFP tables
* harbour/include/dbinfo.ch
* harbour/include/hbrdddbf.h
* harbour/include/hbrddcdx.h
* harbour/include/hbrddnsx.h
* harbour/include/hbrddntx.h
* harbour/source/rdd/dbf1.c
* harbour/source/rdd/workarea.c
+ added support for VFP tables with VARCHAR and VARBINARY fields
+ added support for VFP tables with NULLABLE fields
+ added new dbFieldInfo() action to check if given field is NULL, f.e.:
? dbFieldInfo( DBS_ISNULL, FieldPos( <cFieldName> ) )
The above modifications were not tested with real VFP files. I do
not have VFP. VFP users should make some real life tests with tables
created by VFP.
