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.
at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)
at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)

at Service.Amende(String dossierId) in c:\projects\ListReports\App_Code\Service.cs:line 36
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
