帮我看看动态设置DBGird的FiledName

[cinderellafelix]

for(int i=0;i<DBGrid1->Columns->Count;i++)
{
TColumn *column=DBGrid1->Columns->Items[i];
column->FieldName=ADOQuery1->Fields[i]->FieldName;
ADOQuery1->Fields[i]->DisplayWidth=10;
}

其中
column->FieldName=ADOQuery1->Fields[i]->FieldName;
ADOQuery1->Fields[i]->DisplayWidth=10;
都有错误，这是为什么呀？

DBGrid1->Columns->Items[0]->FieldName = ADODataSet1->Fields->Fields[0]->FieldName;
ADODataSet1->Fields->Fields[0]->DisplayWidth = 10 ;

[controstr]

for( int i = 0 ; i < ADODataSet1->FieldCount ; ++i )
{
DBGrid1->Columns->Add() ;
DBGrid1->Columns->Items[i]->FieldName = ADODataSet1->Fields->Fields[i]->FieldName;
ADODataSet1->Fields->Fields[i]->DisplayWidth = 10 ;
}

ADOQuery1不能进行Fields操作吗？

寫程序要靈活運用
for( int i = 0 ; i < ADOQuery1->FieldCount ; ++i )
{
DBGrid1->Columns->Add() ;
DBGrid1->Columns->Items[i]->FieldName = ADOQuery1->Fields->Fields[i]->FieldName ;
ADOQuery1->Fields->Fields[i]->DisplayWidth = 10 ;
}
