I'm not sure I had those exact problems when binding ADO recordset fields directly to VFP textboxes but I had others, such as errors when the recordset wasn't open yet (there's no fields collection then). I use the Refresh and Valid methods/events of the textbox to set and read the recordset data. It's a concept I took from this Jim Booth article:

That article and this other one http://msdn.microsoft.com/library/techart/adojump.htm by John Petersen got me going on ADO, HTH.
