c# - Reporting Services (.RDLC) Two Datasets -

-

i have .rdlc 2 datasources. when using datasource named "dslancamentos", working fine. now, i've add second one, named "dsdespesas", , report viewer throws message:

a data source instance has not been supplied data source 'dsdespesas'.

and here code:

var dsreportlancamentos = new dsreportlancamentostableadapters.pr_report_lancamentostableadapter(); var dsreportdespesas = new dsreportlancamentostableadapters.pr_report_sea_despesastableadapter(); var tabela = (datatable)dsreportlancamentos.getdata(txtnomeproduto.text, funcoes.getdatetimevalueornull(datade), funcoes.getdatetimevalueornull(dataate), funcoes.getbytevalueornull(status)); var despesas = (datatable)dsreportdespesas.getdata(funcoes.getdatetimevalueornull(datade), funcoes.getdatetimevalueornull(dataate));   // configuraÇÕes report ----------------------- reportdatasource rds = new reportdatasource("dslancamentos", tabela); reportdatasource rdsdespesa = new reportdatasource("dsdespesas", despesas); rvreport.reset(); rvreport.processingmode = processingmode.local; rvreport.localreport.reportpath = server.mappath("~/reports/lancamentosreport.rdlc"); rvreport.localreport.datasources.add(rds); rvreport.localreport.datasources.add(rdsdespesa); // -----------------------------------------------

can me this? can't find whats wrong.

tks.

(i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
