ok. i did that but i am still getting the same error.
i want to use rxdblookupcombo to show two fields at the same time( first and second names).
If i use rxdblookupcombo on a new project i don't get the error and that's why i suspect that there is a conflict with other libraries .
rxnew is fully installed and ( ExtendedNotebook, kgrids, kedits, SpkToolbar,
spkt_Tab, spkt_Pane, spkt_Buttons, DBGrids,
JvDBLookup, RLBarcode, IBLookupComboEditBox,
jdblabeledcurrencyedit,Laz2_DOM ) they are all new as well.
