Hello,

i imported the sample c# class into a nvo.

When i try to open the nvo, powerbuilder crashes.

Error in the eventlog:

Great, but not so great, I still get the feeling it's risky to have multiple installations of PB on the same machine, though others will claim everything works great.

Hi,

 

i think the crash has nothing to do with the c# sharp importer.

 

I get the crash on every object, that i try to open.

I can not even create any object.

As soon as i try to create something with the painter the powerbuilder crashs.

Ill try to reinst to see if that fixes my problem.

Sounds like reinstall is a good idea. Consider uninstall; then reboot; then install once more. Just to minimize risk of some leftovers mess up the new install.

Hi Ferdinand,

I downloaded your project and attempted to open your .DLL with C# Class Importer. However, I got this error:

Could not load file or assembly 'file …\PBcSharpTest.dll' or one of its dependencies.
Operation is not supported. (Exception from HRESULT 0x80131515)

So, I opened your C# solution in SnapDevelop, recompiled without ANY changes to code, project setup, or solution. Simply recompile. This version I have no issues opening.

I can generate the proxy (CSharpObject descendant). I can open the generated proxy object. All seems fine.

I have NO idea what is different. So I have uploaded your project once more. This time with my compiled version in the DEBUG subfolder. Maybe someone else will have fun comparing files to see where the difference is. I have to focus on my day job rest of today.

/Michael

hmm that reminds me: we haven't tested yet (or at least "I") whether this dll import will work on a 'clean' machine. When we compile the dll's with VS, there might be some stuff on GAC (don't know, I'm a noob). So that will be my next test: test from powerbuilder, once we have imported a dll, on a different machine, where the dll has NOT been compiled ...

:)

Maybe powerbuilder needs another .Net Framework to be installed (even though you can compile in C# with 4.7.1)?

This is all the stuff that's on my pc:

Hi again,

I've downloaded your test sample, downloaded and installed .net framework 4.7.1 and compiled it with VS 2019 Community.

Then imported the DLL from the debug folder with all checked in advanced options.

Double click on the nvo from the library painter, all okay.

Did the same thing for the DLL in the release folder, with prefix "nvo_release_" , but without the "encapsulate a CsharpAssembly object ....." checked.

Same result, all okay.

So ... what's different? I'm on W10.

 

I've attached my result in zip format, see if you can open the nvo's.

Okay, so that indicates it might be something on your system. Can you try on a different PC or VM?

Do you have more than one PB version installed on same PC?

I'm out of options., sorry

Under "About C# Assembly" in the help, .Net Framework 4.7.1 is not listed:


The C# assembly supported by PowerBuilder must be developed on .NET Framework 4.0 or later or .NET Standard 1.0 or later. And the assembly DLL file will require the corresponding version of .NET Framework to run, especially if the DLL file is a .NET Standard class library. Please check the Microsoft website or the following table for the compatible versions between .NET Standard and .NET Framework.

Nevertheless, I'm downloading 4.7.1 to give it a try, please hold on a few mintues:

 

The C# assembly supported by PowerBuilder must be developed on .NET Framework 4.0 or later or .NET Standard 1.0 or later. And the assembly DLL file will require the corresponding version of .NET Framework to run, especially if the DLL file is a .NET Standard class library. Please check the Microsoft website or the following table for the compatible versions between .NET Standard and .NET Framework.

Hi Ferdinand,

Thanks for reporting this problem.

1. I downloaded the VS-Project you provided but can't reproduce it on our side either.

2. Please use another machine to test and see if the same issue exists.

3. If you can also reproduce it on other machine, I also suggest you report it to our support ticketing system : https://www.appeon.com/standardsupport/newbug

When you report this issue, please also provide a sample PB test case (with PBT / PBL) for us to reproduce it. Thanks in advance.

Regards,

Hi Ferdinand,

When you double-click the nvo object / window on the left panel in PB IDE, the window displayed on the right is implemented based on PBUDO190.dll.

Hi Ferdinand,

If you tell me where I can get "the sample C# class", I'll try to do the same thing.

What type of project did you create in C#?

.net standard ?

.net framework ?

.net core ?

Only the first 2 seem to be valid.

Can you post your c# project?

Meanwhile I'll try....
