need a quicker way to select data and paste it in an excel sheet

It took me a while to just find a way to select data from my database and then paste it in an excel spreadsheet. Now that I've found it, it runs dirt slow. Like I said before, I've looked at a lot of different ways to accomplish this but have not been able to correctly implement any of them except for this. I'm not married to this option but it is the only one I could get to work. Could someone help me out by suggesting a quicker way to accomplish this simple task? Please see my code below.
Record850 rec850 = new Record850();
List<Record850> lst850records = new List<Record850>();
//SqlConnection connStr = new SqlConnection("Server = 172.18.211.76; Database = Processstage; User Id = brendon.davies; Password = mypassword;");
SqlConnection conn = new SqlConnection("Server = 172.18.211.76; Database = Processstage; User Id = brendon.davies; Password = mypassword;");
//SqlConnection sqlConnection1 = new SqlConnection(conn);
SqlCommand cmd = new SqlCommand();
SqlDataReader reader;
cmd.CommandText = Select_850;
cmd.CommandType = CommandType.Text;
cmd.Connection = conn;
conn.Open();
Record850 reco850 = new Record850();
string strComplete = "";
reader = cmd.ExecuteReader();
while (reader.Read())
{
try
{
reco850.OrgName = reader.GetString(0);
reco850.WholeSalerAccountDivisionCode = reader.GetString(1);
reco850.File_Process_Name = reader.GetString(2);
reco850.Pur_Ord_Num_BEG03 = reader.GetString(3);
reco850.File_Process_ID = reader.GetInt64(4);
reco850.CECode = reader.GetString(5);
reco850.CEName = reader.GetString(6);
reco850.Modified_Date = reader.GetDateTime(7);
lst850records.Add(reco850);
reco850 = new Record850();
}
catch(Exception e)
{
Console.WriteLine(e.ToString());
}
}
conn.Close();
eWorkSheet = (Excel.Worksheet)oSheets.get_Item("850_Template");
eWorkSheet.Activate();
int int850counter = 0;
int int850RowCounter = 3;
foreach (Record850 r850 in lst850records)
{
strComplete = lst850records[int850counter].OrgName + "\t" +
lst850records[int850counter].WholeSalerAccountDivisionCode + "\t" +
lst850records[int850counter].File_Process_Name + "\t" +
lst850records[int850counter].Pur_Ord_Num_BEG03 + "\t" +
lst850records[int850counter].File_Process_ID + "\t" +
lst850records[int850counter].CECode + "\t" +
lst850records[int850counter].CEName+ "\t" +
lst850records[int850counter].Modified_Date;
CR = (Excel.Range)eWorkSheet.Cells[int850RowCounter,3];
Clipboard.SetText(strComplete);
CR.Select();
eWorkSheet.Paste(CR, false);
Clipboard.Clear();
int850RowCounter++;
int850counter++;
strComplete = ""
}

Here's an answer that also runs quickly, just about the same as the use of EPPlus above. Do not attempt the cell by cell approach (commented out below) as that indeed runs at a snail's pace by comparison.
[STAThread]
static void Main(string[] args)
{
Excel.Application xl = null;
try {
xl = new Excel.Application();
xl.ScreenUpdating = false;
xl.Visible = false;
xl.UserControl = false;
var wb = xl.Workbooks.Open(SOURCE_PATH);
var ws = (Microsoft.Office.Interop.Excel.Worksheet)wb.Sheets.Item["850_Template"];
StringBuilder sb = new StringBuilder();
//int row = 3;
// var a1 = ws.Range["A1", Missing.Value];
using (SqlConnection cn = new SqlConnection(CN_STR)) {
cn.Open();
using (SqlCommand cmd = new SqlCommand(SQL, cn)) {
cmd.CommandType = CommandType.Text;
using (SqlDataReader dr = cmd.ExecuteReader()) {
while (dr.Read())

sb.AppendFormat("{0}\t{1}\t{2}\t{3}\t{4}\t{5}\t{6}\t{7}\r\n",

(string)dr["File_Process_Name"],
(string)dr["Pur_Ord_Num_BEG03"],
(long)dr["File_Process_ID"],

);
//a1.Offset[row, 0].Value = (string)dr["OrgName"];

//a1.Offset[row, 5].Value = (string)dr["CECode"];
//a1.Offset[row, 6].Value = (string)dr["CEName"];
//a1.Offset[row, 7].Value = (DateTime)dr["Modified_Date"];
//row++;
}
}
}
cn.Close();
}
Clipboard.SetText(sb.ToString(),
TextDataFormat.Text);
var rng = ws.Range["A3", Missing.Value];
rng.Select();
ws.Paste(rng, Missing.Value);
Clipboard.Clear();
wb.Save();
wb.Close();

} catch (Exception ex) {
Console.WriteLine(ex.Message);

Here's an alternative that uses the EPPlus approach, much faster.
try {
var app = new ExcelPackage(new FileInfo(SOURCE_PATH));
var ws = app.Workbook.Worksheets["850_Template"];
int row = 3;
using (SqlConnection cn = new SqlConnection(CN_STR)) {
cn.Open();
using (SqlCommand cmd = new SqlCommand(SQL, cn)) {
cmd.CommandType = CommandType.Text;
using (SqlDataReader dr = cmd.ExecuteReader()) {
while (dr.Read())
{
ws.SetValue(row, 1, (string) dr["OrgName"]);
ws.SetValue(row, 2, (string) dr["WholeSalerAccountDivisionCode"]);
ws.SetValue(row, 3, (string) dr["File_Process_Name"]);
ws.SetValue(row, 4, (string) dr["Pur_Ord_Num_BEG03"]);
ws.SetValue(row, 5, (long) dr["File_Process_ID"]);
ws.SetValue(row, 6, (string) dr["CECode"]);
ws.SetValue(row, 7, (string) dr["CEName"]);
ws.SetValue(row, 8, (DateTime) dr["Modified_Date"]);
row++;
}
}
}
cn.Close();
}
app.Save();
} catch (Exception ex) {
Console.WriteLine(ex.Message);

How To insert data into SQL Sever with C# without using the database wizard(visual studio)

I'm having trouble inserting data into my table called "client" in my database called "vet".
I'm trying to do the connection manually as opposed to using the database wizard. I want to do it this way so that i can hide the majority of my code in a separate class.
I have a feeling I have the logic for this all wrong as I'm not making use of a data set, I was hoping someone could point me in the right direction.
This is for a school assignment and not for real world use. I have read a number of similar posts but am still unable to come to a solution.
public void CommitToDatabase()
{
using (var con = new SqlConnection(CLSDatabaseDetails.GlobalConnectionString))
{
DataTable client = new DataTable();
DataSet ds = new DataSet();
string commandString = "SELECT * FROM client";
SqlCommand cmd = new SqlCommand(commandString, con);
con.Open();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(client);
DataRow newClientRow = ds.Tables["client"].NewRow();
newClientRow["ClientID"] = ClientID;
newClientRow["FirstName"] = FirstName;
newClientRow["LastName"] = LastName;
newClientRow["Phone"] = PhoneNumber;
newClientRow["CAddress"] = Address;
newClientRow["Email"] = Email;
newClientRow["CUsername"] = Username;
newClientRow["CPassword"] = Password;
client.Rows.Add(newClientRow);
da.Update(client);
}
}

A DataSet is a collection of DataTables. In your example, you're only referring to one table. The SqlDataAdapter.Fill method will populate either DataSet or DataTable. You're calling da.Fill(client) which is fine - it will fill the DataTable client. You could also call da.Fill(ds, "client") which will fill the DataSet ds. You can then extract your table via ds.Tables["client"]. Using a DataSet in this example is overkill, but you can show your tutor how a DataSet works.
You're filling the DataTable but then adding the new row with reference to the DataSet. But in your example, the DataSet ds has nothing in it, because you filled the DataTable not the DataSet. Try this:
DataSet ds = new DataSet();
string commandString = "SELECT TOP 0 * FROM client";
SqlCommand cmd = new SqlCommand(commandString, con);
con.Open();
SqlDataAdapter da = new SqlDataAdapter(cmd);
SqlCommandBuilder builder = new SqlCommandBuilder(da);
da.Fill(ds, "client");
DataTable client = ds.Tables["client"];
DataRow newClientRow = client.NewRow();
... ... ...
client.Rows.Add(newClientRow);
builder.GetInsertCommand();
da.Update(client);
If you only want to insert a row, you don't need to SELECT all the rows. If you SELECT TOP 0 * from client you'll get the column names (which you need) but without the overhead of returning all the rows.

Try something like this:
public void CommitToDatabase()
{
using (var con = new SqlConnection(CLSDatabaseDetails.GlobalConnectionString))
{
DataTable client = new DataTable();
string commandString = "SELECT * FROM client";
SqlCommand cmd = new SqlCommand(commandString, con);
con.Open();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(client);
DataRow newClientRow = client.NewRow();
newClientRow["ClientID"] = ClientID;
newClientRow["FirstName"] = FirstName;
newClientRow["LastName"] = LastName;
newClientRow["Phone"] = PhoneNumber;
newClientRow["CAddress"] = Address;
newClientRow["Email"] = Email;
newClientRow["CUsername"] = Username;
newClientRow["CPassword"] = Password;
client.Rows.Add(newClientRow);
da.Update(client);
}
}

How to View Crystal report in Visual Studio 2013?

I'm working on ASP.Net with C#, and installed CrystalReport 13 for Visual Studio 2013. I wrote code to fill a Datasource and pass it into my `CrystalReport file, but my website doesn't show anything. How can I execute my report?
Here is my PageLoad:
SqlConnection cnn = new SqlConnection(connectionstring);
cnn.Open();
SqlCommand command = new SqlCommand();
SqlDataAdapter adapter = new SqlDataAdapter();
DataSet ds = new DataSet();
command.Connection = cnn;
command.CommandType = CommandType.StoredProcedure;
command.CommandText = "STP_T00050030";
command.Parameters.Add("#F_CNTRowID", SqlDbType.Int).Value = Convert.ToInt32("20");
command.Parameters.Add("#F_CNTid", SqlDbType.Int).Value = Convert.ToInt32("45");
adapter = new SqlDataAdapter(command);
adapter.Fill(ds);
ReportDocument crystalReport = new ReportDocument();
crystalReport.Load(Server.MapPath("~/Report1.rpt"));
crystalReport.SetDataSource(ds);
CrystalReportViewer1.ReportSource = crystalReport;

In your solution, right mouse click on each report (.rpt file) and go properties --> Build Action=Content, Copy To Output Directory=Copy Always
Here's a complete block of code for setting data source. Notice how data source must also be set for each subreport.
public static CrystalReportSource Crystal_SetDataSource(string reportName, object par1, object par2, object par3)
{
CrystalReportSource CrystalReportSource2 = new CrystalReportSource();
CrystalReportSource2.CacheDuration = 10;
CrystalReportSource2.Report.FileName = #"~\App_Pages\Secure\Reports\" + reportName;
CrystalDecisions.CrystalReports.Engine.Database crDatabase = CrystalReportSource2.ReportDocument.Database;
ConnectionInfo crConnectionInfo = new ConnectionInfo();
crConnectionInfo.ServerName = server;
crConnectionInfo.DatabaseName = db;
crConnectionInfo.UserID = crystalUser;
crConnectionInfo.Password = pwd;
crConnectionInfo.IntegratedSecurity = false;
// First we assign the connection to all tables in the main report
TableLogOnInfo crTableLogOnInfo = new TableLogOnInfo();
foreach (CrystalDecisions.CrystalReports.Engine.Table crTable in crDatabase.Tables)
{
crTableLogOnInfo = crTable.LogOnInfo;
crTableLogOnInfo.ConnectionInfo = crConnectionInfo;
crTable.ApplyLogOnInfo(crTableLogOnInfo);
}
//SET DATASOURCE FOR EACH SUBREPORT IN REPORT
foreach (CrystalDecisions.CrystalReports.Engine.Section section in CrystalReportSource2.ReportDocument.ReportDefinition.Sections)
{
// In each section we need to loop through all the reporting objects
foreach (CrystalDecisions.CrystalReports.Engine.ReportObject reportObject in section.ReportObjects)
{
if (reportObject.Kind == ReportObjectKind.SubreportObject)
{
SubreportObject subReport = (SubreportObject)reportObject;
ReportDocument subDocument = subReport.OpenSubreport(subReport.SubreportName);
foreach (CrystalDecisions.CrystalReports.Engine.Table table in subDocument.Database.Tables)
{
// Cache the logon info block
TableLogOnInfo logOnInfo = table.LogOnInfo;
// Set the connection
logOnInfo.ConnectionInfo = crConnectionInfo;
// Apply the connection to the table!
table.ApplyLogOnInfo(logOnInfo);
}
}
}
}
if (CrystalReportSource2.ReportDocument.DataSourceConnections.Count > 0)
CrystalReportSource2.ReportDocument.DataSourceConnections[0].SetConnection(server, db, crystalUser, pwd);
CrystalReportSource2.ReportDocument.SetDatabaseLogon(crystalUser, pwd, server, db);
if (par1 != null)
CrystalReportSource2.ReportDocument.SetParameterValue(0, par1);
if (par2 != null)
CrystalReportSource2.ReportDocument.SetParameterValue(1, par2);
if (par3 != null)
CrystalReportSource2.ReportDocument.SetParameterValue(2, par3);
return CrystalReportSource2;
}

Slow data Selection from MDB file to C# Desktop application

Although everything is correct, but data selection process is very slow in my Application, while retriving data from access .mdb file. Is there any idea that data can be accessed fast. Is there any mechanism??
This below code Runs when Button Clicked .
