  Hi
  
  I have a webforms app using C1Report which all works fine on my dev machine. Just deployed it to Azure App Service and all the reports generate a runtime error which appears to be something to do with fonts. Here is the stack trace:

  [ArgumentException: Parameter is not valid.]

  Any help fixing this would be much appreciated.
  
  Thanks

  Hi Jonathan,
  
  For information, the C1Report is obsolete and please use the FlexReport instead of C1Report as much as possible.

  Could you please the C1 version you are using?
  
  Please make sure that the C1 is installed on the server.
  
  The server is licensed for C1.
  
  It would be great if you may share a small demo sample depicting your issue.

  Regards,
  
  Manish Gupta

  Hi
  
  C1Report version is 4.6.20142.54737.
  
  I have a webforms page with this markup:

  Report Viewer - VIMS

  The report is configured and filled with data in business layer and placed in a session variable.
  
  The following code executes in Page_Load event:

  
          protected void Page_Load(object sender, EventArgs e)
          {
              if (Session["CurrentReport"] != null)
              {
                  C1.C1Report.C1Report report;
                  report = (C1.C1Report.C1Report)Session["CurrentReport"];
                  System.IO.MemoryStream stream = new System.IO.MemoryStream();
                  HttpResponse rsp = this.Page.Response;
                  rsp.Buffer = true;
  
                  report.Render();
                  report.C1Document.Export(stream, 	  C1.C1Preview.Export.ExportProviders.PdfExportProvider);
  
                  rsp.Clear();
                  rsp.ContentType = "application/pdf";
                  int length = Convert.ToInt32(stream.Length);
                  rsp.OutputStream.Write(stream.GetBuffer(), 0, length);
                  rsp.Flush();
                  rsp.SuppressContent = true;
                  Session.Remove("CurrentReport");
              }
          }
  
  

  Any help much appreciated.

  Hello Jonathan,
  
  Thank you for your code and sorry for the inconvenience. C1Report uses the System.Drawing (GDI) for export process in various format which is not supported by the Azure App service. Please refer to the following link for reference:
  
  https://feedback.azure.com/forums/169385-web-apps/suggestions/12864567-support-for-gdi

  That is why you are getting the Runtime error for deployed application on Azure.
