如题:我的代码:
adoxCatalog: _Catalog;
adoxTable: _Table;
adoxColumns: Columns;窗体创建时: adoxcatalog := cocatalog.Create;打开表时 :
con1.GetTableNames(cbbTbl.Items, false);
adoxcatalog.Set_ActiveConnection(con1.ConnectionObject);
adoxtable := adoxcatalog.Tables[cbbTbl.ItemIndex + sysTblCount];
//系统表不显示
adoxcolumns := adoxtable.Columns;然后
with adoxcolumns[colIndex] do
begin
for ipts := Properties.Count - 1 downto 0 do
if properties.item[ipts].Name = 'Default' then
begin
sResult + Properties[ipts].Value;
break;
end;
end;
ShowMessage(sResult);出现错误,提示---------------------------
