the app work fine when play from VB.NET but when using smart assemply to merge dll files the app works fine but when trying to print any report error displayed:

"

Error occurred during local report processing

"

i think exe file cant see report file >> how can i solve this problem

What I have tried:

string dt = DateTime.Now.ToShortDateString();

                var traAmount = 54533.77;
                var from_acc = "45646456434";
                var from_name = "Wess hjg Marko";
                var to_acc = "8686783234";
                var to_name = "Sarah";
                var user_name = "Sarah";
                //====================================================

                string tafq = "";
                Hoorof.clsHoorofArabic horof = new Hoorof.clsHoorofArabic();
                if (float.Parse(traAmount.ToString()) > 999999999.99)
                {
                    tafq = "";
                }
                else if (float.Parse(traAmount.ToString()) <= 0)
                {
                    tafq = "";
                }
                else
                {
                    tafq = horof.تحويل_الأرقام_الى_حروف(Convert.ToDecimal(traAmount.ToString()), 2, "جنيه مصري", " قرش", true, true);
                }
                //====================================================
                DateTime x = Convert.ToDateTime(dt);
                ReportParameter p1 = new ReportParameter("dt", x.ToString("yyyy/MM/dd"));
                ReportParameter p2 = new ReportParameter("amt", traAmount.ToString());
                ReportParameter p3 = new ReportParameter("from_name", from_name);
                ReportParameter p4 = new ReportParameter("from_num", from_acc);
                ReportParameter p5 = new ReportParameter("to_num", to_acc);
                ReportParameter p6 = new ReportParameter("to_name", to_name);
                ReportParameter p7 = new ReportParameter("user_nm", user_name);
                ReportParameter p8 = new ReportParameter("amt_tafkit", tafq);

                rep_view.ProcessingMode = ProcessingMode.Local;
                rep_view.LocalReport.DataSources.Clear();
                rep_view.LocalReport.ReportEmbeddedResource = "FCUBS_Remapping_Tool.Transfer_App.rdlc";

                rep_view.LocalReport.SetParameters(p1);

Solution 1

You need to exclude the problematic method or class from obfuscation.
If I remember well, SmartAssembly offers several methods for merging dll's, you can also try another method.
If that does not work exclude the misbehaving dll from SmartAssembly.
Alternatives are using ILmerge utility or Fody Costura:
Mike Barnett at Microsoft Research[^]
GitHub - Fody/Fody: Extensible tool for weaving .net assemblies[^]

ILmerge example:

C#

ilmerge /target:winexe /out:SelfContainedProgram.exe Program.exe ClassLibrary1.dll ClassLibrary2.dll

Also see: Merging .NET assemblies using ILMerge[^]

----------------------------------------------------------------------------------
Another example which keeps the name of the .exe the same:

Put ILMerge in a folder ILMerge in your solution.

Define a Post-Build event:
On the Project menu, click Properties.
Select the Build Events tab.
In the Post-build event command line box, type your commands

Example:

"$(SolutionDir)\ILMerge\ILMerge.exe" /target:winexe /out:wessam.exe WindowsFormsApplication1.exe Microsoft.ReportViewer.Common.dll Microsoft.ReportViewer.DataVisualization.dll Microsoft.ReportViewer.ProcessingObjectModel.dll Microsoft.ReportViewer.WinForms.dll
DEL WindowsFormsApplication1.exe 
REN wessam.exe WindowsFormsApplication2.exe

----------------------------------------------------------------------------------

I think this article has a solution for your ILMerge problem: Adding DOC, RTF, and OOXML Export Formats to the Microsoft Report Viewer Control[^]

thank you RickZeeland for replaying
can y help me and tell me how can i use ILmerge to merge report viewer on my exe file

weswes88 3-Jun-17 14:08pm

i am using this code before but the output file cant open
ilmerge /target:winexe /out:SelfContainedProgram.exe Program.exe ClassLibrary1.dll ClassLibrary2.dll

RickZeeland 3-Jun-17 14:13pm

No, you have to use the post-build event if you want to do it from Visual Studio.
You have to replace the file names by the names of your files.

weswes88 3-Jun-17 16:02pm

i used code above in .csproj file like this here
and when save it and reload project this message appear THIS
sorry .. can you tell me how can do this by steps >> i am not do this before .. Mercy
this is my code

<PostBuildEvent>
    if $(ConfigurationName) == Release ("$(SolutionDir)\..\VMS\3rdParty libs\ILMerge\ILMerge.exe" /target:winexe /out:Wessam.exe FCUBS_Remapping_Tool_By_Wessam.exe clsHoorof.dll Microsoft.ReportViewer.Common.dll Microsoft.ReportViewer.WinForms.dll Microsoft.ReportViewer.DataVisualization.dll Microsoft.ReportViewer.ProcessingObjectModel.dll
    DEL FCUBS_Remapping_Tool_By_Wessam.exe
    REN Wessam.exe FCUBS_Remapping_Tool_By_Wessam.exe)
  </PostBuildEvent>

weswes88 3-Jun-17 17:12pm

is this code is right

"$(SolutionDir)\ILMerge\ILMerge.exe" /target:winexe /out:wessam.exe FCUBS_Remapping_Tool_By_Wessam.exe clsHoorof.dll Microsoft.ReportViewer.Common.dll Microsoft.ReportViewer.DataVisualization.dll Microsoft.ReportViewer.ProcessingObjectModel.dll Microsoft.ReportViewer.WinForms.dll
DEL FCUBS_Remapping_Tool_By_Wessam.exe 
REN wessam.exe FCUBS_Remapping_Tool_By_Wessam.exe

i did strps above and build project after save code
but this error apper when compile app
THIS

RickZeeland 4-Jun-17 1:53am

The post-build command looks right to me, but as I don't have your project and dll's I can not check if the names are spelled correctly.
Also ILMerge is not perfect, escpecially large and more complicated programs can give problems ...

RickZeeland 4-Jun-17 2:17am

It could be that you are missing Microsoft.ReportViewer.WebForms.dll, even if it is not used by your application, there might be a reference to it that is causing the error.

weswes88 4-Jun-17 12:16pm

hello mrRickZeeland Download it
this is sample from my project
can you test code on it and send me feedback

RickZeeland 4-Jun-17 15:42pm

Good news, your application builds and runs ! but you have to put the ILMerge folder in the solution folder (where the .sln file is).
Tested with VS2013 Community ed. on Win 10 Home.

RickZeeland 4-Jun-17 16:18pm

Hmmmm, it only would build because the Microsoft.ReportViewer dll's were in your output folder. A Rebuild failed with the error you got.
The only way I could do a rebuild was by including the Microsoft.ReportViewer dll's in the project and set the property "Copy to output directory" to "Copy always".
Not ideal, but it works, I could generate a pdf and view it with logo and text.

RickZeeland 4-Jun-17 16:36pm

Sorry, when trying to run WindowsFormsApplication2.exe standalone it crashes. No sensible information in the Windows Eventlog. I'm afraid Microsoft.ReportViewer is not suitable for merging with ILMerge. I think you can better try another reporting solution or PDF library.

weswes88 4-Jun-17 17:00pm

thank alot for your tring >> can you send me your project after editing ..
and i dont know anther reporting solution can you tell me what is it control and how using it in my project thanks agin

RickZeeland 4-Jun-17 17:09pm

I got the standalone running, just had to add the .exe.config file !
Still gives a "strong naming" warning, but it shows the report viewer.

weswes88 4-Jun-17 17:33pm

the report viewer show empty and 'strong naming" error appear >>
what can i do now

RickZeeland 5-Jun-17 2:04am

You won't like it, but I think the answer is here: https://www.codeproject.com/articles/23966/report-viewer-generate-reports-ms-word-formats?msg=4207320
Quote: "We plan to hack assemblies by modifying their IL code; therefore, we will be forced to remove their strong names and public keys.".
I don't use strong naming myself, exactly because of this sort of problem that can also arise if you use third party unsigned dll's in your signed application. But when I have time I will have another go at it.

Solution 2

Finally got it working, download here: WindowsFormsApplication2[^]
I used Fody Costura, with the normal Microsoft Reportviewer dll's it would not work (wrong reference path probably).
So I installed Microsoft Reportviewer 2010 NuGet packages:
- Microsoft Report Viewer 2010 SP1 Common Libraries
- Microsoft Report Viewer 2010 SP1 Windows Forms

I did not test on a "bare" system where the Reportviewer dll's are not present, but I'm pretty sure it will work.
Let me know if everything works as expected !

thanks alot mr RickZeeland
you are right the program work well when tring to open it from PC have report viewer on it
but when tring to open it from antoer PC same message appear "Error occurred during local report processing"
can you explain to me the difference between the 2 report viewer and from where you are got it .. and how can we solve this problem
-----------
IMPORTANT NOTE ::
you Must Know mr RickZeeland that EXE file work well When Copy
Microsoft.ReportViewer.Common.dll And Microsoft.ReportViewer.ProcessingObjectModel.dll
beside it

RickZeeland 5-Jun-17 13:03pm

I don't know exactly what the difference is between the "normal" Microsoft Reportviewer and the NuGet package, but apparently Fody Costura works better with NuGet packages. Although Fody Costura should have less problems with signed libraries than ILMerge. Maybe you can try adding other Microsoft Reportviewer NuGet packages, like 2012 and 2015 until it works on your other PC.
Of course your resulting .exe size will grow a bit :)

How Can I Get NutGet Packages 2015

RickZeeland 5-Jun-17 13:26pm

To get Reportviewer 2015 packages from NuGet, in Visual Studio goto Tools - NuGet Package Manager and search for "Microsoft Reportviewer 2015".
For questions about Fody Costura maybe you can create an "issue" on https://github.com/Fody/Costura, or contact one of the developers, I don't think they have a forum.

weswes88 5-Jun-17 13:39pm

can i use crystal report instead of report viewer ??

RickZeeland 5-Jun-17 14:37pm

In my early computing days I once used Crystal Reports with VB6, but I'm afraid I'm not up to date with that now. So maybe it's better to post that as a separate question on CodeProject. If you only need to generate a pdf from code you could also use a pdf library like PDFsharp, http://www.pdfsharp.net.

weswes88 5-Jun-17 18:16pm

is that mean there is now hope to do this with report viewer

RickZeeland 6-Jun-17 4:45am

Did you mean "no hope" ? I would not say that, but it will take a lot of time and experimenting with NuGet packages.
Looking back, it would probably have been easier to ditch Microsoft Reportviewer and use an open source solution or something that can be merged more easily.
Nevertheless I found this an interesting experience, and learned a lot from it !

weswes88 6-Jun-17 11:16am

Thanks a lot Mr RickZeeland For You Help and Replays
i am glad to speaking with you >>
I will Search for More NuGet Package and i will tell you the result
thanks again
