repotviewer.ReportSource = dp;            
repotviewer.SelectionFormula = "Date({transaksi1.masuk})=Date('" +skr+ "') ";
repotviewer.RefreshReport();
repotviewer.Refresh();

Answer 1

答案是，安装另一个与 XP 兼容的 MySql 连接器，然后在 MyODBC 中创建连接。

更改代码如下：

skr = DateTime.Now.ToString("yyyy/MM/dd");
dp = new DailyParking();
dp.SetDatabaseLogon("user", "passwd", "host", "dbname");
dp.RecordSelectionFormula = "Date({transaksi1.masuk}) = Date('" + skr + "') ";
repotviewer.ReportSource = dp;
repotviewer.Refresh();

使用安装在 XP 和 Rebuil 程序中的新 MySQL 连接器更改 MySQL.Data 引用。
