Hi!

 

If anyone wants I have successfully connected via SOAP to MSRS to render any report.

 

* Connection using SOAP and THttpRio component;

* Using ReportService2010 and ReportExecution2005 webservices;

* Basic authentication;

* Get list of reports of any folder;

* Pass parameters;

* Render the report in any format (PDF, EXCEL, MHTML, HTML4.0, HTML3.2, TIFF and every format MSRS supports);

* Send the stream (file) to the user of UniGUI.

 

The only thing I didn't do yet is get list of parameters, what is not difficult, but in my current frame I pass the parameters I know the report needs.

 

Bye!

Hi!

 

Sorry for the delay. And I don't have time to make a sample and the procedure to Render the report is used for one of my reports only. If you want a generic procedure you should do changes like remove the two hardcoded parameters in the procedure. Test with a simple report first.

 

 

 

 

1) IMPORT CLASSES IN YOUR PROJECT (Delphi -> Menu Component -> Import WSDL)

        ReportExecution2005 (http://YOURSERVER/ReportServer/ReportExecution2005.asmx?wsdl)
        ReportService2010 (http://YOURSERVER/ReportServer/ReportService2010.asmx?wsdl)

 

 

 

 

 

2) DECLARE IN THE FORM YOU WILL CALL THE REPORT:

		procedure TYOURFORM.Rio1HTTPWebNode1BeforePost(
		  const HTTPReqResp: THTTPReqResp; Data: Pointer);
		var
		  user,pass: string;
		begin
		  user := 'srv-test\administrador';
		  pass := 'yourpassword'; // the same account / password you use when using the browser to view the reports

		 if not InternetSetOption(Data,
					   INTERNET_OPTION_USERNAME,
					   PChar(user),
					   Length(user)) then
			 ShowMessage(SysErrorMessage(GetLastError));

		  if not InternetSetOption(Data,
					   INTERNET_OPTION_PASSWORD,
					   PChar(pass),
					   Length (pass)) then
			 ShowMessage(SysErrorMessage(GetLastError));

		end;

		// PARAMETERS DataEnt and CodComprador YOU SHOULD CHANGE FOR YOUR REPORT PARAMETER
		function TYOURFORM.RenderReport1(stm: TStream; const ExtFormat: string;
		  DataEnt: TDateTime; CodComprador: integer):boolean;
		const
		  ServiceURL = 'http://YOURSERVER/reportserver/ReportService2010.asmx'; // change for YOUR SERVER 
		  ExecURL = 'http://YOURSERVER/reportserver/ReportExecution2005.asmx';
		var
		  //rs: ReportService2010.ReportingService2010Soap;
		  rsExec: ReportExecution2005.ReportExecutionServiceSoap;


		  setParams: ReportExecution2005.SetExecutionParameters;
		  setParamValues: ReportExecution2005.ArrayOfParameterValue;
		  LRParams: ReportExecution2005.LoadReport;
		  LoadParamsResponse: ReportExecution2005.LoadReportResponse;

		  renderParams: ReportExecution2005.Render;
		  renderResponse: ReportExecution2005.RenderResponse;
		  setParamsResponse: ReportExecution2005.SetExecutionParametersResponse;

		  execInfo: ReportExecution2005.ExecutionInfo;
		  execHeader, renderHeader: ReportExecution2005.ExecutionHeader;

		  I: integer;

		  //args: array [0..4] of string;
		  Rio1: THttpRio;
		begin
		  result := false;

		  LoadParamsResponse := nil;
		  setParamsResponse := nil;

		  Rio1 := THttpRIo.Create(nil);

		  Rio1.HTTPWebNode.OnBeforePost := Rio1HTTPWebNode1BeforePost;
		  Rio1.HTTPWebNode.UserName := 'extrafruti\administrador';
		  Rio1.HTTPWebNode.Password := 'yourpassword'; // the same account / password you use when using the browser to view the reports

		  {Rio2.HTTPWebNode.UserName := 'srv-teste\administrador';
		  Rio2.HTTPWebNode.Password := '*****';}

		  //rs := ReportService2010.GetReportingService2010Soap(False, ServiceURL, Rio2);
		  rsExec := ReportExecution2005.GetReportExecutionServiceSoap(False, ExecURL, Rio1);

		  execInfo := ReportExecution2005.ExecutionInfo.Create;
		  execHeader := ReportExecution2005.ExecutionHeader.Create;

		  LRParams := ReportExecution2005.LoadReport.Create;
		  setParams := ReportExecution2005.SetExecutionParameters.Create;
		  renderHeader := ReportExecution2005.ExecutionHeader.Create;
		  renderResponse := ReportExecution2005.RenderResponse.Create;
		  renderParams := ReportExecution2005.Render.Create;

		  try
			  try
				  setlength(setParamValues,0);

				  // Load the selected report.
				  LRParams.Report := '/teste2'; // the report name in the root folder in this case
				  LoadParamsResponse := rsExec.LoadReport(LRParams);

				  // Send ExecutionHeader
				  execHeader.ExecutionID := LoadParamsResponse.executionInfo.ExecutionID;
				  Rio1.SOAPHeaders.Send(execHeader);


				  // SET LENGTH EQUAL TO THE NUMBER OF PARAMETERS OF THE REPORT
				  // AND PASS IN THE ARRAY LIKE I DID
				  SetLength(setParamValues, 2);
				  // parâmetro 1 (FIRST PARAMETER)
				  setParamValues[0] := ReportExecution2005.ParameterValue.Create;
				  setParamValues[0].Name_ := 'DATA_ENT';
				  setParamValues[0].Value := FormatDateTime('dd/MM/yyyy',DataEnt);
				  // parâmetro 2 (SECOND PARAMETER)
				  setParamValues[1] := ReportExecution2005.ParameterValue.Create;
				  setParamValues[1].Name_ := 'COD_COMPRADOR';
				  setParamValues[1].Value := IntToStr(CodComprador);


				  // change to your language
				  setParams.ParameterLanguage := 'pt-BR';
				  setParams.parameters := setParamValues;

				  setParamsResponse := rsExec.SetExecutionParameters(setParams);

				  renderParams.Format := ExtFormat;

				  // Send RenderHeader
				  renderHeader.ExecutionID := LoadParamsResponse.executionInfo.ExecutionID;
				  Rio1.SOAPHeaders.Send(renderHeader);
				  renderResponse := rsExec.Render(renderParams);

				  stm.Write(renderResponse.Result[0], Length(renderResponse.Result));

				  result := true;

			  except
				  on E: Exception do
				  begin
					MessageDlg(
					  'Error creating report: ' + E.Message + #13#10 +
					  'Please contact.........',
					  mtError, []);
				  end;
			  end;
		  finally
			  for I := Low(setParamValues) to High(setParamValues) do
				if setParamValues[I]<>nil then setParamValues[I].Free;

			  if Assigned(setParamsResponse) then setParamsResponse.Free;
			  if Assigned(renderResponse) then renderResponse.Free;
			  if Assigned(renderParams) then renderParams.Free;
			  if Assigned(execHeader) then execHeader.Free;
			  if Assigned(execInfo) then execInfo.Free;
			  if Assigned(LRParams) then LRParams.Free;

			  Rio1 := nil;
			  //RS := nil;
			  RSExec := nil;

		//      setParams.Free;


		  end;
		end;

3) CALL LIKE THIS

	fname := 'c:\test.html'; // YOUR FILE NAME must be the same extesion you will pass

		stm := TMemoryStream.Create;
		try
		  if RenderReport1(stm,'HTML4.0',UniDateEnt.DateTime,StrToInt(cp)) then // two parameters of my report
		    UniSession.SendStream(stm,ExtractFileName(fname));
		  
		  // you can mail the report too (SEE MY OTHER EXAMPLE IN UNIGUI FORUM)
		finally
		  stm.Free;
		end;

Please, share if you have success. It's working perfectly here.

Sample to get report parameters if needed:

http://msdn.microsoft.com/en-us/library/reportservice2005.reportingservice2005.getreportparameters.aspx

 

And use FindItems to get a list of reports:

http://msdn.microsoft.com/en-us/library/reportservice2005.reportingservice2005.finditems.aspx

 

I didn't use in this project but works because I have used it in another project.

As said, my project runs only one report in that function I shared and I pass the report name and parameters hard coded.

 

Bye!
