*Prepare strCn and strShp * ... With this .CommandType = 1 .ConnectionString = strCn .RecordSource = strShp Endwith * Prepare HierarchicalFlexGrid with ThisForm.HFlex .Datasource = ThisForm.ADOData.Object *....And it works ! As I expected it doesn't on other computers. I already done with "working anywhere" version but I wonder why this works. Any insight is appreciated. TIA.
