VB.Net. Trying to use EasyModbus events gives a "Ambiguous Name" compile error. #6

Open YvesLev opened 6 years ago

For exemple, For VB, coilsChanged event is ambiguous with CoilsChanged (Case Sensitive).

So I have not been able yet to implement the coilsChanged and holdingRegistersChanged Events in VB.Net. Always gives me compile error: ('' is ambiguous because multiple kinds of members with this name exist in '')

But I'm quite new to this I admit, and I might not use it correctly in vb.net...

I just realized that I duplicated your issue with #7. I forked this project and added "Handler" to all delegates. That removes the ambiguity for VB.NET.

I'll push my latest branch so you can try it out from my repository.

See if this forked commit ed7c8c0 works for you.

I downloaded this "forked" version and built it.

Yes the resultant DLL works in VB.Net now!

Thank you!

However, just noticed that when I issue the StopListening() method, I receive an exception in Visual Studio. It does not seem to stop my application though. I tried this fork in C# and same thing happens. But the previous version, the one I took from sourceforge, is working fine for the StopListening.

Here is the exception text from the Output window during debug of my application:
