Can it be an antivirus problem ? Thanks

Ciao Michele,

COLUMNS is not an object means grid has destroyed its columns, happens when (.recordSource) is closed without being cleared:

o = CreateObject('grid')
? o.ColumnCount && -1
use "someTable" alias someAlias 
o.RecordSource = 'someAlias'
? o.ColumnCount && eg. 15
use
? o.ColumnCount && 0
? o.Columns && error "COLUMNS is not an object"

As this error occurs inside FoxInCloud, when identifying changes in the grid, the only cause I see possible is that:

• (.recordSource) is a cursor
• some external program prevents access to the cursor's source located in the VFP or the FiC temp folders (see http://…/foxincloud-status.tuto?&tab=SERVERSTATUS) ; anti-virus is the most probable.
