I got the following message in Visual Foxpro

"General field cannot be used in the where condition of an update statement.
Change the wheretype property of the view"
whenever i use append general to insert a picture
then when I use skip or go top or go bottom I got the above message.
I look at the property and did not understand to much.

Part of the Code

DBSetProp(ThisView,"View","WhereType",1)


DBSetProp(ThisView+".photos","Field","DataType","G")
DBSetProp(ThisView+".photos","Field","UpdateName","dbo.studentinfo.photos")
DBSetProp(ThisView+".photos","Field","KeyField",.F.)
DBSetProp(ThisView+".photos","Field","Updatable",.T.)


thanks a lot
