C# initial experience with FastReport report (picture)

It turns out that the program uses Word and Excel to do some operations of exporting data and printing. However, after running for a period of time, it was found that there were always problems with the Office installed on some users' computers, and they needed to be reinstalled and adjusted, causing some additional maintenance work.

Here is a simple attempt to use FastReport instead of Office to generate some data that needs to be exported in the form of a report. If necessary, it can be saved in excel format, which can reduce some unnecessary troubles.

In the program, the connection information is extracted from the report to avoid the insecurity of the report file. In addition, the connection information can be separately included in the configuration file.

                data = new DataSet();
                sda.Fill(data);
                con.Close();
                sda.Dispose();
            }

            {

            }

            try
            {
                FastReport.Report report = new FastReport.Report();
                //string filename = Application.StartupPath + @"\FrxReport\qualityEvent.frx";
                string filename = @"D:\qualityEvent.frx";

                report.Load(filename);
                report.RegisterData(data);
                report.GetDataSource(data.Tables[0].TableName).Enabled = true;
                report.Show();
            }
            catch (Exception err)
            {
                MessageBox.Show(err.Message);

        }
    }
}

After trying several times, I can only use .Net4. 0, FastReport will be recognized, so the developed project also needs to be reset and the .Net4.0 framework package reinstalled.
