GetReportFromAssembly did not work

[dikan]

I just upgraded my StimulSoft license to Ultimate and after that I have very strange problem.

I have some simple code which I used all over my applications and it works with no problem

Report = StiReport.GetReportFromAssembly(fileName);

and now it does not work any more.
I recompiled my dll (assembly files) with new designer but nothing changed.

Any clue?

[dikan]

I triad with .MRX files with code like this and it works without problems.

.Load(file)
.Compile
.Render

Maybe this helps.

Hello,

Did you receive any error messages? Can you post full error stack? Usually its a problem of incompatible versions of the reporting tool that loads the assembly and the version of the reporting tool which create report assemblies.

Thank you.

Do you need any additional information about this?

Hello,

Sorry, but I cannot say something by the full error stack, because the error occur before calling the designer. .dll files attached are not loaded, and we cannot reproduce the error.
Could you please send the report (the project) so that we can compile it and try to run.

Thank you.

[dikan]

Problem is with every report in DLL format.
I have no problems with running reports from Designer or running them from .MRX format within application. Only DLL format.
It is slowing down my application and I don't know what to do. I tried to remove every trace of old installation so I believe that previously mentioned possible reason is not an option now.
BTW I already sent you one of those reports few days ago in my other thread which is about PageFooter. This report I also can not run as .DLL

Regards,

Djordje

I also use this method extensively, and I just might be able to throw some light on the subject.

When you change the version of StimulReports you need to regenerate any dll's created by the previous version.

In my programs I usually catch this exception and use the uncompiled report to regenerate (recreate) the dll, this way the user does not know that anything untoward has happened. Of course another way around this would be to eliminate all report dll's after updating StimulReports.

HTH,
Martin.

Hello,

This is not restriction of Stimulsoft. This is feature of .Net Framework. You need use same versions of assemlies which referenced and which loaded. Also you can use following code to generate automatically new version of report assembly:

Code: Select all

private void RenderReport(ReportAction reportAction)
        {
            if (tvReports.SelectedNode != null && tvReports.SelectedNode.Parent != null)
            {
                string file = StiConfig.ApplicationDirectory + "\\" + "Reports\\" + tvReports.SelectedNode.Tag as string;

                if (File.Exists(file))
                {
                    StiReport report = new StiReport();
                    report.Load(file);

                    string folder = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
                    folder = Path.Combine(folder, "Stimulsoft\\CompiledReports");
                    folder = Path.Combine(folder, System.Runtime.InteropServices.RuntimeEnvironment.GetSystemVersion().ToString());
                    string compiledReportFile = Path.Combine(folder, report.GetReportAssemblyCacheName());


                    if (File.Exists(compiledReportFile))
                    {
                        lbStatus.Text = "Loading report from assembly";
                        Application.DoEvents();
                        report = StiReport.GetReportFromAssembly(compiledReportFile, true);

                        RegData(report, (string)tvReports.SelectedNode.Tag);

                        lbStatus.Text = "Rendering report";
                        Application.DoEvents();
                        report.Rendering += new EventHandler(OnRendering);
                        int tick = Environment.TickCount;

                        report.Render(false);

                        btTest.Text = (Environment.TickCount - tick).ToString();
                    }
                    else
                    {
                        lbStatus.Text = "Loading report";
                        Application.DoEvents();

                        RegData(report, (string)tvReports.SelectedNode.Tag);

                        lbStatus.Text = "Compiling report";
                        Application.DoEvents();

                        if (!Directory.Exists(folder)) Directory.CreateDirectory(folder);

                        report.Compile(compiledReportFile);

                        lbStatus.Text = "Rendering report";
                        Application.DoEvents();
                        if (report.CalculationMode == StiCalculationMode.Compilation)
                        {
                            report.CompiledReport.Rendering += new EventHandler(OnRendering);
                        }
                        else
                        {
                            report.Rendering += new EventHandler(OnRendering);
                        }
                        int tick = Environment.TickCount;
                        report.Render(false);
                        btTest.Text = (Environment.TickCount - tick).ToString();
                    }

                    if (!report.IsStopped)
                    {
                        if (reportAction == ReportAction.PreviewInWindow)
                        {
                            report.Show(true);
                        }
                        else if (reportAction == ReportAction.Preview)
                        {
                            stiViewerControl1.Report = report;
                            //stiViewerControl1.FirstPage();
                        }
                        else if (reportAction == ReportAction.Print) report.Print();
                    }

                    lbStatus.Text = "";
                }
                else MessageBox.Show("'" + tvReports.SelectedNode.Tag as string + "' not found");
            }
        }

This is method from Demo application. If report is changed or version of report generator is changed then report engine will generate new report assembly.

Thank you.

I know that new version needs recompiling so I did that long ago before I started this thread.
I believe that this is not my problem. In this very moment I do not know where to look but something will come up.
If I have some question during my investigation I will ask you. :redeye:
