GROUP BY p.Personal_Name, p.Personal_Family, p.Personal_FingerId, w.Work_Date
ORDER BY w.Work_Date

Answer 1

I haven't handle crystal report in a while but I'm pretty sure you have to click on the Crystal Report Viewer object in your WinForm and change the property to no login required. In addition, when referring to a file path use this convention: @"C:\\directory\\word.txt" for your cryRpt.Load(@"D:\\c#\\AttendanceApp\\AttendanceApp\\CrystalReport_Work.rpt").

Try the below example, be sure to set your DataSource.

private void Form1_Load(object sender, EventArgs e)
{
CustomerReport crystalReport = new CustomerReport();
Customers dsCustomers = GetData();
crystalReport.SetDataSource(dsCustomers);
this.crystalReportViewer1.ReportSource = crystalReport;
this.crystalReportViewer1.RefreshReport();
}

private Customers GetData()
{
string constr = @"Data Source=.\Sql2005;Initial Catalog=Northwind;Integrated Security = true";
using (SqlConnection con = new SqlConnection(constr))
{
    using (SqlCommand cmd = new SqlCommand("SELECT TOP 20 * FROM Customers"))
    {
        using (SqlDataAdapter sda = new SqlDataAdapter())
        {
            cmd.Connection = con;
            sda.SelectCommand = cmd;
            using (Customers dsCustomers = new Customers())
            {
                sda.Fill(dsCustomers, "DataTable1");
                return dsCustomers;
            }
        }
    }
}

}
