Hi,
I am trying to use the feature that include PowerBuilder to Import .NET DLLs.
So I have created a very basic app with PowerBuilder that include a non visual object imported with the Tool .NET DLL Importer.
This non visual object is a C# .NET DLL made with Visual Studio 2019.

The DLL is very simple, it contains a function that return a string. 'ok'

public string Text()
{
string ret="OK";
return ret;
}

I had guided in this video to do all the steps until I deployed the app.

 

When I deploy the Target it works on my computer because I have all .Net and Framework .NET and Core... due to installation of visual studio 2019.

The big problem for me is when I have to deploy on the other machines.
I know that I have to install .NET (at this time 6.0) and put the DLL in the same directory. Maybe I am missing something in this point.

The app opens, but when I call the dll do not nothing.
I have put a simple comand button in the window. On clicked event call the non visual object function (DLL). But it did not nothing. It is suposed to return OK as a messagebox.

I made the same thing with C++ dll and imported as a extension (Import PB Extension...) and it worked.

On the client computer I have all the dll's of PowerBuilder plus the .NET DLL and C++ DLL.

I read about the PDFUtils post that Bruce Armstong made: https://community.appeon.com/index.php/codeexchange/powerbuilder/286-pdfutils
and more or less is the same way I want to do but with my code. So I downloaded the files, I put on other machine that has .Net Core installed and it worked.

I am sure that I am missing something but I don't know what is it...

Thanks! :) smile
