oledbdataadapterC#oledbdataAdapter.怎么用把ACCESS中的数据绑定到combobox选项中？？

OleDbDataAdapter只能执行select类型的查询语句吗？？

用法错误 OleDbDataAdapter da = new OleDbDataAdapter(sql, conn); // Create the Insert, Update and mands. da.InsertCommand = new OleDbCommand( "INSERT INTO Customers (CustomerID, CompanyName) " + "VALUES (?, ?)"); da.UpdateCommand = new OleDbCommand( "UPDATE Customers SET CustomerID = ?, CompanyName = ? " + "WHERE CustomerID = ?"); da.DeleteCommand = new OleDbCommand( "DELETE FROM Customers WHERE CustomerID = ?");

vs08用什么控件代替oledbdataadapter控件

是这个步骤。

在TOOLBOX中点右键—ADD framework-oledbdataadapter即可添加这个控件

OleDbConnection和DataSet和OleDbDataAdapter和Olecommand 有什么关系

oledbconnection建立连接 mand执行insert和update命令 OleDbDataAdapter.fill(dataset)执行select命令并把结果放到dataset中

获取数据 OledbConnection myconn = new OledbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & server.mappath("tushu.mdb") & ";Persist Security Info=False");//改成具体的数据库 myconn.Open(); string strsql = "select * from table"; //改成具体的表格 OledbDataAdapter dpt = new OledbDataAdapter(strsql,myconn); DataTable dt = new DataTable(); dpt.Fill(dt); myconn.Close(); 填boBox for(int i = 0;i < dt.Rows.Count;i++) { boBox1.Items.Add(dt.Rows[i][0].ToString());//默认取第一列的数据 }
