I have a Word document, where I have to replace text and save this document in Oracle database, in PDF format. Have someone any idea how to resolve this?

I want to send DataSet data with email excel file attachment in C# but I don't want to create Excel file physically. It can be do with MemoryStream but I couldn't.
Another problem I want to set Excel file's encoding type because data may be Russian or Turkish special character.
Please help me...
Here is my sample code...
<!-- language: c# -->
var response = HttpContext.Response;
response.Clear();
response.Charset = "utf-8";
response.ContentEncoding = System.Text.Encoding.Default;
GridView excelGridView = new GridView();
excelGridView.DataSource = InfoDataSet;
excelGridView.DataBind();
excelStringWriter = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(excelStringWriter);
excelGridView.RenderControl(htw);
byte[] ExcelData = emailEncoding.GetBytes(excelStringWriter.ToString());
MemoryStream ms = new MemoryStream(ExcelData);
mailMessage.Attachments.Add(new Attachment(ms, excelFileName, "application/ms-excel"));
<!-- language: c# -->
here is another one simple and easy with excel attchment
public string SendMail(string LastId)
{
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["con"].ConnectionString);
SqlCommand cmd = new SqlCommand("sp_GetMailData", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("#LastID", LastId);
con.Open();
string result = "0";
string temptext = "";
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt=new DataTable();
da.Fill(dt);
//ExportToSpreadsheet(dt,"My sheet");
GridView gv = new GridView();
gv.DataSource = dt;
gv.DataBind();
AttachandSend(gv);
con.Close();
return result.ToString();
}
public void AttachandSend(GridView gv)
{
StringWriter stw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(stw);
gv.RenderControl(hw);
System.Text.Encoding Enc = System.Text.Encoding.ASCII;
byte[] mBArray = Enc.GetBytes(stw.ToString());
System.IO.MemoryStream mAtt = new System.IO.MemoryStream(mBArray, false);
System.Net.Mail.MailMessage mailMessage = new System.Net.Mail.MailMessage();
MailAddress address = new
MailAddress("xxxxxxxxxxxxx", "Admin");
mailMessage.Attachments.Add(new Attachment(mAtt, "sales.xls"));
mailMessage.Body = "Hi PFA";
mailMessage.From = address;
mailMessage.To.Add("xxxxxxxxxxxx");
mailMessage.Subject = "xxxxxxxxxxxxxx";
mailMessage.IsBodyHtml = true;
var smtp = new SmtpClient();
smtp.Send(mailMessage);
}
Here is your solution
private static Stream DataTableToStream(DataTable table)
{
const string semiColon = ";";
var ms = new MemoryStream();
var sw = new StreamWriter(ms);
foreach (DataColumn column in table.Columns)
{
sw.Write(column.ColumnName);
sw.Write(semiColon);
}
sw.Write(Environment.NewLine);
foreach (DataRow row in table.Rows)
{
for (int i = 0; i < table.Columns.Count; i++)
{
sw.Write(row[i].ToString().Replace(semiColon, string.Empty));
sw.Write(semiColon);
}
sw.Write(Environment.NewLine);
}
return ms;
}
private static MailMessage CreateMail(string from,
string to,
string subject,
string body,
string attname,
Stream tableStream)
{
// using System.Net.Mail
var mailMsg = new MailMessage(from, to, subject, body);
tableStream.Position = 0;
mailMsg.Attachments.Add(
new Attachment(tableStream, attname, CsvContentType));
return mailMsg;
}
private const string CsvContentType = "application/ms-excel";
private static void ExportToSpreadsheetInternal(Stream tableStream, string name)
{
HttpContext context = HttpContext.Current;
context.Response.Clear();
context.Response.ContentType = CsvContentType;
context.Response.AppendHeader(
"Content-Disposition"
, "attachment; filename=" + name + ".xls");
tableStream.Position = 0;
tableStream.CopyTo(context.Response.OutputStream);
context.Response.End();
}
public static void ExportToSpreadsheet(DataTable table, string name)
{
var stream = DataTableToStream(table);
var mailMsg = CreateMail("from#ddd.com",
"to#ddd.com",
"spread",
"the spread",
name,
stream);
//ExportToSpreadsheetInternal(stream, name);
// send the mailMsg with SmtpClient (config in your web.config)
var smtp = new SmtpClient();
smtp.Send(mailMsg);
}
Call this method
ExportToSpreadsheet(DataTable table, string name)

Your question is not very clear, I don't know what you mean when you say "the content is not allowed in prolog", however it looks like you have some extra characters in your code. Was this part a copy-paste error? You have the > symbols in front of each of these lines.

Hii Guys !!!
I made an application in which i need to export data from database into .excel formate in which i have given hard coded path for generated .excel file to save at particular position on the system.Now as per my requirement I need to give download option for openwith and saveAs from the browser.
Below I am postion my code .Plz guys help me ...will be gratefull.Thanx in advance...
String datum1 = request.getParameter("fromdate");
String datum2 = request.getParameter("todate");
SimpleDateFormat sdfSource = new SimpleDateFormat("dd-MM-yyyy");
Date date = sdfSource.parse(datum1);
Date date2 = sdfSource.parse(datum2);
SimpleDateFormat sdfDestination = new SimpleDateFormat("yyyy-MM-dd");
datum1 = sdfDestination.format(date);
System.out.println(datum1);
datum2 = sdfDestination.format(date2);
System.out.println(datum2);
String filename = "d:/".concat(datum1).concat(" ").concat("To").concat(" ").concat(datum2).concat(".xls");

rowhead.createCell((short) 1).setCellValue("src");
rowhead.createCell((short) 2).setCellValue("dst");
String strQuery = "";
ResultSet rs = null;
conexion conexiondb = new conexion();
conexiondb.Conectar();
strQuery = "SELECT * FROM cdrcost where date(calldate) between '" + datum1 + "' and '" + datum2 + "'";

rs = conexiondb.Consulta(strQuery);
int i = 1;
while (rs.next()) {
HSSFRow row = sheet.createRow((short) i);
row.createCell((short) 0).setCellValue(rs.getString("calldate"));
row.createCell((short) 1).setCellValue(rs.getString("src"));
row.createCell((short) 2).setCellValue(rs.getString("dst"));
i++;
}
FileOutputStream fileOut = new FileOutputStream(filename);
hwb.write(fileOut);
fileOut.close();
System.out.println("Your excel file has been generated!");
} catch (Exception ex) {
System.out.println(ex);
}
}
You should use Content-Disposition in the response header
Try using this code
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition",
"attachment;filename=FileName.xls");
OutputStream out = response.getOutputStream();
FileInputStream in = new FileInputStream(my_file);
byte[] buffer = new byte[4096];
int length;
while ((length = in.read(buffer)) > 0){
out.write(buffer, 0, length);
}
in.close();
out.flush();
