Auto-Save to PDF ASP.NET C#

It is ASP.NET code in C#. Since you need to get the report in binary on
server side (reporting server), hence the ASP.NET.

save a report on the server side, you can call Reporting Services'
web services to generate the report, render it in desired format and save
it.

I just write a peice of code to allow user to request a report to be send to
a given email address as an attachment. Here is the simplified code (note,
you need to add web reference to the reporting services' web services):

private void GetReportByEmail()
{
//Validate txtEmail for inputting
if (txtEmail.Text.ToUpper().StartsWith("XX"))
{
lblPrompt.Text="You must enter a valid email address!";
lblPrompt.Visible=true;
return;
}

if (txtEmail.Text.IndexOf("@")<3) text="You must enter a valid email address!" visible="true;" rs="new" url="http://localhost/ReportServer/ReportService.asmx" credentials="System.Net.CredentialCache.DefaultCredentials;" report="/WDTimeSheets/TimeSheetEmp/PayrollSummary" historyid="null;" deviceinfo="null;" pmts="new" pmt="new" name="EmployeeID" value="lblEmpID.Text;" pmt="new" name="FromDate" value="DateTime.Parse(ddlFrom.SelectedValue).ToString(" pmt="new" name="ToDate" value="DateTime.Parse(txtTo.Text).ToString(" credentials="null;" showhide="null;" encoding="null;" mimetype="null;" pmtused="null;" warnings="null;" streamids="null;" reportdata="rs.Render(report," class="hilite4">PDF",historyID,deviceInfo,pmts,credentials,showHide,
out encoding,out mimetype,out pmtUsed,out warnings,out streamIDs);
}
catch(System.Web.Services.Protocols.SoapException ex)
{
lblPrompt.Text=ex.Message;
lblPrompt.Visible=true;
return;
}

//Save PDF report to a temp location
string
folder=System.Configuration.ConfigurationSettings.AppSettings["TempDataFolder"];
if (Directory.Exists(folder))
{
//Get a random file name
string f="PayRollSummary_" + DateTime.Today.ToString("yyyy-MM-dd") + "_"
+ lblEmpID.Text;

string fileName=folder + "\\" + f + ".pdf";

//Save the report (PDF) in a configured location
try
{
if (File.Exists(fileName)) File.Delete(fileName);
FileStream fs=File.OpenWrite(fileName);
fs.Write(reportData,0,reportData.Length);
fs.Close();
}
catch(System.IO.IOException ex)
{
lblPrompt.Text=ex.Message;
lblPrompt.Visible=true;
return;
}

//Send PDF file with email
EmailReport(fileName); //Method is omitted
}
else
{
lblPrompt.Text="Web server configuration error: emailing operation was
cancelled.";
lblPrompt.Visible=true;
}
}
