SSRS ReportExecution2005.asmx call with code/ C# / https

As stated in my prior post I have been working on InfoPath Forms Services. During the development of a form I wanted to attach a pdf version of the form in an email during submission. I have researched several ways to accomplish this task and the solution I used was to call reporting services. This call would allow me to return a memorystream and attach it to my email in code. In my case the difficult part was to make sure the call worked from both https and http calls. One key note to take into consideration is to make the web service url call directly from the Forms Collection your are currently in. This will ensure the proper creds are passed and "DefaultCreds" will work. Below I have provided a code sample on how to make the call and return a pdf in a memory stream.

Report Server Web Service Endpoints

Sample of Code:
private MemoryStream FormSubmitGetReportAttachment()

// Render arguments
byte[] result = null;
string reportPath = "http://moss/Reports/Sales/Review.rdl";
string format = "PDF";
string historyID = null;
string devInfo = @"False";
// Prepare report parameter.
ParameterValue[] parameters = new ParameterValue[1];
parameters[0] = new ParameterValue();
parameters[0].Name = "ApptKey";
parameters[0].Value = ApptKey.ToString();

//DataSourceCredentials[] credentials = null;
//string showHideToggle = null;
string encoding;
string mimeType;
string extension;
Warning[] warnings = null;
//ParameterValue[] reportHistoryParameters = null;
string[] streamIDs = null;

ReportExecutionService rs = new ReportExecutionService();
rs.Credentials = System.Net.CredentialCache.DefaultCredentials;
//rs.Credentials = new NetworkCredential(user, pass, domain);
rs.Url = "https://moss/Forms/_vti_bin/ReportServer/ReportExecution2005.asmx";
rs.ExecutionHeaderValue = new ExecutionHeader();

ExecutionInfo execInfo = rs.LoadReport(reportPath, historyID);
String SessionId = rs.ExecutionHeaderValue.ExecutionID;
rs.SetExecutionParameters(parameters, "en-us");

result = rs.Render(format, devInfo, out extension, out encoding, out mimeType, out warnings, out streamIDs);

MemoryStream ms = new MemoryStream();
ms.Write(result, 0, result.Length);
ms.Position = 0;
return ms;
catch (SoapException e)
ErrorMessage(e, true, e.Detail.OuterXml);
return null;
catch (Exception ex)
return null;
