Parameters via a web service

Hy,

I have to build a report. this report has to be call by a web service. My method to call this report is :

---

[WebMethod]

public void Amende()

{

ReportingService rs = new localhost.ReportingService();

rs.Credentials = System.Net.CredentialCache.DefaultCredentials;

byte[] ResultStream; // bytearray for result stream

string[] StreamIdentifiers; // string array for stream idenfiers

string OptionalParam = null; // string out param for optional parameters

ParameterValue[] optionalParams = null; // parametervalue array for optional parameters

Warning[] optionalWarnings = null; // warning array for optional warnings

ResultStream = rs.Render("/SwatFillingDocuments/AMAD AYDIN 1198 2005 MD", "PDF", null,

"<DeviceInfo><StreamRoot>/RSWebServiceXS/</StreamRoot></DeviceInfo>", null, null,

null, out OptionalParam, out OptionalParam, out optionalParams,

out optionalWarnings, out StreamIdentifiers);

// Write the report to Response

HttpContext.Current.Response.BinaryWrite(ResultStream);

}

---

But in my report I have a parameter. And I have to give a value at this parameter via my web service. Is it possible to do that with the method Render?

oki I found how to give a parameter. So my code looks like that now:

[WebMethod]

public void Amende( string dossierId )

{

ReportingService rs = new localhost.ReportingService();

rs.Credentials = System.Net.CredentialCache.DefaultCredentials;

byte[] resultStream; // bytearray for result stream

string[] streamIdentifiers; // string array for stream idenfiers

string optionalParam = null; // string out param for optional parameters

ParameterValue[] optionalParams = null; // parametervalue array for optional parameters

// Prparation de la valeur passe en paramètre

ParameterValue[] parameters = new ParameterValue[1];

parameters[0] = new ParameterValue();

parameters[0].Name = "DossiersId";

parameters[0].Value = dossierId;

DataSourceCredentials[] credentials = null;

string showHideToggle = null;

string historyID = null;

Warning[] optionalWarnings = null; // warning array for optional warnings

resultStream = rs.Render("/SwatFillingDocuments/AMAD AYDIN 1198 2005 MD", "PDF",

historyID, @."False", parameters,credentials,showHideToggle,out optionalParam,

out optionalParam,out optionalParams, out optionalWarnings,out streamIdentifiers);

HttpContext.Current.Response.BinaryWrite(resultStream);

}

But when I put a parameter in my web service I have an error :

System.Net.WebException: The request failed with HTTP status 400: Bad Request.

Can you help me please? If I use this mothed without parameter it works but when i try to give a parameter it fails.Thank you|||

I do this in VB. This writes the report out to a disk after you get the byte array. This code is from inside a class that I wrap the process in so I havent't looked at it in awhile but it has been working without errors.

Public Sub RenderWriter()

Dim parameters() As MyReportService.ParameterValue

parameters = GetParameters()

Dim encoding As String

Dim mimeType As String

Dim parametersUsed() As MyReportService.ParameterValue

Dim warnings() As MyReportService.Warning

Dim streamIds() As String

'render the report

Dim data() As Byte

'data = _rs.Render(Me._ReportItem.Path, _Format.Name, Nothing, Nothing, parameters, Nothing, Nothing, encoding, mimeType, parametersUsed, warnings, streamIds)

data = _rs.Render(ReportItem.Path, Format.Name, Nothing, Nothing, parameters, Nothing, Nothing, encoding, mimeType, parametersUsed, warnings, streamIds)

'//create a file stream to write the output

'Dim fileName As String = _OutputPath & "\" & _ReportItem.Name & _Format.Extension

Write(data)

End Sub

Private Sub Write(ByVal data() As Byte)

Dim fs As New System.IO.FileStream(Me.FileName, System.IO.FileMode.OpenOrCreate)

Dim writer As New System.IO.BinaryWriter(fs)

writer.Write(Data, 0, Data.Length)

writer.Close()

fs.Close()

End Sub

Private Function GetParameters() As MyReportService.ParameterValue()

Dim i As Integer

Dim len As Integer = _ParamValues.Count - 1

Dim returnValues(len) As MyReportService.ParameterValue

For i = 0 To len

returnValues(i) = New MyReportService.ParameterValue

returnValues(i).Name = _ParamValues.Item(i).Name

returnValues(i).Value = _ParamValues.Item(i).Value

Next i

Return returnValues

End Function
