I am so close to getting my last report up and running. I have not had this problem with any other reports. I am trying to create a report based off a database record. When I go to create the report by LocalReport and creating the parameters for the report I get the error message ‘Managed Debugging Assistant 'PInvokeStackImbalance' : 'A call to PInvoke function 'Microsoft.ReportViewer.Common!Microsoft.ReportingServices.Rendering.ImageRenderer.FontPackage::CreateFontPackage' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.' This is a .rdlc report for my MVC project. The record is correct and the values get inserted but when I go to display it /create it the report errors out. On the line ‘renderedBytes = localReport.Render(
/* TRACKER_TEST Database Connection ~ Debugging & Testing */
TRACKER_TESTDataSet dataSet = new TRACKER_TESTDataSet();
TRACKER_TESTDataSetTableAdapters.Service_Report_FieldsTableAdapter adapter = new TRACKER_TESTDataSetTableAdapters.Service_Report_FieldsTableAdapter();
LocalReport localReport = new LocalReport();
localReport.ReportPath = Server.MapPath("~/ReportForms/VirtualService2.rdlc");
List<TRACKER_TESTDataSet.Service_Report_FieldsRow> report = new List<TRACKER_TESTDataSet.Service_Report_FieldsRow>();
foreach(var row in list)
{
report.Add(adapter.GetDataBy(row.SN1, row.SN2).First());
}
ReportDataSource rds = new ReportDataSource("Service_Data", report);
localReport.DataSources.Add(rds);
